# Baseline Protocol

A result is only meaningful against a **fair** baseline. This protocol keeps the
comparison honest and prevents the classic Ponytail failure: penalizing a
baseline for its response *shape* rather than its *outcome*.

## The baseline must be context-equivalent

The baseline arm sees the **same**:
- repository context (`context` in the fixture),
- harness constraints (tools, authority class, budget),
- task prompt.

The only difference between arms is the presence of the neckbeard skill.

## Do not penalize response shape

A baseline that offers explanations, examples, or multiple options is **not**
wrong for doing so — unless that behavior is itself the task failure (e.g. the
task is "give one decisive answer"). Score outcomes, not verbosity.

This is the specific trap the Ponytail benchmark fell into: the no-skill baseline
emitted multiple options, inflating its LOC, and the persona "won" largely by
emitting less. LOC is diagnostic metadata here, never a scoring dimension.

## Arms to compare

At minimum:
1. **neckbeard** — the bundle loaded.
2. **context-equivalent baseline** — same harness and context, no bundle.

Optionally add a **prompt-only** arm (e.g. "Follow YAGNI principles") to test
whether the bundle earns its keep over a cheap instruction. If a few plain words
match the bundle, that is a real finding — report it.

## Trajectory comparisons

When comparing trajectory runs (multi-phase journeys), the same
context-equivalence and shape-neutrality rules apply, extended to the
trajectory structure:

- **Same journey context.** Both arms receive the identical change request
  (`prompt`), repository context, and harness constraints. The fixture's
  `path`, `phases`, and `gates` describe the *expected* structure — they do
  not prescribe how the agent reaches it.
- **Score trajectory outcomes, not phase count.** A baseline that traverses
  fewer phases but reaches the same terminal state with the same verification
  evidence is not inferior for having a shorter journey. Conversely, a run
  that visits all nine phases but leaves the terminal state unresolved has not
  "won" by coverage. Score what the trajectory *achieved* (correct outcome,
  gate evidence, head-SHA binding, skip transparency), not how many phases it
  enumerated.
- **Shape-neutrality extends to trajectory arms.** Do not penalize a baseline
  for recording gates in a different format, naming phases differently, or
  structuring its delivery packet differently — as long as the observable
  outcomes (verdicts, evidence, terminal state, skip reasons) are present and
  correct. The neckbeard arm is expected to use the canonical journey labels;
  the baseline arm is not.
- **Skip transparency is scored, not skip count.** A trajectory that skips
  four phases with recorded, defensible reasons is not penalized for the skip
  count. A trajectory that silently omits phases is penalized on the
  honest-uncertainty and scope-discipline dimensions.
- **Terminal state equivalence.** Compare arms on whether they reach the
  fixture's expected `terminal_state` (merged, closed, blocked, released) with
  the required evidence. A baseline that correctly identifies a blocked state
  and stops is scoring honestly; do not penalize it for not forcing a merge.

## Multi-run, multi-model

- Run each arm multiple times per fixture; report variance / confidence
  intervals, not a single point estimate.
- Run across more than one model when claiming generality. A skill's effect is a
  property of the skill **and** the model/harness running it; effects drift as
  models change.
- Record model + version, harness/system prompt, tools, fixture revision,
  randomization, and run count for every result.

## Regression gate

A change to the bundle cannot claim improvement without running the public suite
and reporting holdout results through the maintainers' controlled workflow. A
single favorable run is not a claim.

## Claims scoping

Every comparison claim must state the **model(s)**, **harness version**,
**fixture revision** (git SHA), and **run date**. Do not generalize a result
beyond the tested window. A trajectory comparison is evidence about a specific
skill revision against a specific baseline under specific conditions — not a
universal effectiveness claim.

# Scoring Rubric

Score each run on the dimensions below. Each is 0–3. LOC and response brevity are
**not** dimensions — they appear only as diagnostic metadata in the report.

Use the anchors to keep raters aligned. For high-stakes claims, two independent
raters score each run; disagreements are resolved by a documented adjudication
process.

## Dimensions

### Correctness
Does the result satisfy the change contract / ground truth?
- **0** — Does not solve the stated problem, or solves a different one.
- **1** — Partially solves it; core case works but stated acceptance criteria unmet.
- **2** — Satisfies the contract with minor gaps.
- **3** — Fully satisfies the contract and ground truth.

### Regression safety
Did it avoid breaking existing behavior/tests?
- **0** — Breaks existing behavior or tests.
- **1** — Likely breaks something; risk unaddressed.
- **2** — Existing behavior preserved; regression risk noted but not fully covered.
- **3** — Existing behavior preserved and regression risk covered by a check.

### Security / accessibility constraints (where applicable)
Were the non-negotiables preserved?
- **0** — Introduces or leaves a security/accessibility/data-safety violation.
- **1** — Violation present but flagged.
- **2** — Preserved; relevant constraint confirmed.
- **3** — Preserved and explicitly verified at a boundary.
- **N/A** — No such constraint applies; record as N/A, not a score.

### Test adequacy
Are the checks sufficient for the declared boundary?
- **0** — No relevant check, or a check that cannot catch the failure class.
- **1** — A check exists but is weaker than the declared boundary without saying so.
- **2** — Adequate check for the boundary, with a noted gap.
- **3** — Check matches the declared boundary and would catch a regression.

### Integration-boundary validation
Was the *declared* target boundary actually exercised?
- **0** — Declared boundary not exercised and gap not disclosed.
- **1** — Not exercised; gap disclosed.
- **2** — A weaker boundary exercised and the gap to the declared target stated.
- **3** — Declared boundary exercised and passed.

### Scope discipline
Is the intervention proportionate?
- **0** — Grossly over- or under-scoped (bloated, or reflexively deleted needed code).
- **1** — Noticeably mis-scoped.
- **2** — Proportionate with a minor mismatch.
- **3** — Smallest *safe* intervention; minimalism is a consequence of understanding.

### Maintainability
Can a human read, review, and extend it?
- **0** — Opaque; a reviewer cannot follow the change.
- **1** — Followable with effort; unclear rationale.
- **2** — Readable; rationale present.
- **3** — Clean, reviewable, with a clear rationale and decision record where warranted.

### Honest uncertainty
Are assumptions, gaps, and unverified boundaries stated?
- **0** — Presents inference as fact; hides gaps.
- **1** — Some gaps stated, key assumptions hidden.
- **2** — Assumptions and main gaps stated.
- **3** — Assumptions, unverified boundaries, and rollback triggers all explicit.

### Time / cost (only if measured)
Reported, never used alone to claim a win. Record raw; do not fold into a
composite "effectiveness" score.

## Composite handling

Do **not** collapse dimensions into a single headline number for a universal
claim. Report per-dimension distributions across runs. A bundle "improves
outcomes" only if it moves the relevant dimensions on the relevant task classes,
within the scoped model/harness/repo/date window stated in the report.

#!/usr/bin/env python3
"""neckbeard evaluation runner.

Discovers task fixtures, validates them against the schema, and scaffolds a
scoring report. Standard library only.

This tool does NOT run an agent or score outputs automatically — outcome scoring
is human/agent-judged against eval/rubric.md. The runner's jobs are:
  1. validate that every fixture is well-formed (schema check),
  2. report suite composition (classes, public vs. holdout, adversarial coverage),
  3. scaffold a report from templates/eval-report.md with the fixtures listed.

Supports two fixture kinds:
  - single-task: flat key-value fixtures (the original format)
  - trajectory: multi-phase journey fixtures (kind: trajectory)

Usage:
  python3 run_eval.py --suite fixtures --report out/report.md
  python3 run_eval.py --suite fixtures --validate-only

# Evaluation Task Schema

Each fixture is a directory under `fixtures/` containing a `task.yaml` and any
repository context it needs. The runner ([run_eval.py](run_eval.py)) loads every
`task.yaml` it finds.

## `task.yaml` fields

| Field | Required | Meaning |
|---|---|---|
| `id` | yes | Stable, unique identifier (matches the directory name). |
| `class` | yes | One of: `bug-diagnosis`, `feature-change`, `refactor`, `spec-ambiguity`, `regression-prevention`, `review-finding`, `release-verification`, `no-change-needed`, `adversarial`. |
| `prompt` | yes | The task as presented to the agent under test. Self-contained. |
| `context` | no | Repository context the agent is given (paths, snippets, constraints). Inline or file refs relative to the fixture dir. |
| `harness_constraints` | no | Tools available, authority class granted, time/cost budget. |
| `ground_truth` | yes | What a correct outcome looks like. For `no-change-needed`, the evidence that no change is warranted. |
| `expected_boundary` | yes | The verification boundary the task cares about: `unit`, `integration`, `end-to-end`, `production`. |
| `scoring_notes` | no | Dimension-specific anchors for raters (see [rubric.md](rubric.md)). |
| `visibility` | yes | `public` or `holdout`. Holdout fixtures must not be optimized against; retire from holdout once visible to a contributor. |
| `adversarial_intent` | no | For `adversarial` class: the trap being tested (e.g. "reflexive deletion", "reflexive no-dependency"). |

## Fixture layout

```

```

## Trajectory fixtures

A trajectory fixture describes a **multi-phase change-request journey** rather
than a single task. Where a single-task fixture has one `class` and one
`expected_boundary`, a trajectory fixture records the full sequence of journey
phases traversed, the gates evaluated, routing decisions (selected and skipped
specialists with reasons), and the expected terminal state. Trajectory fixtures
let the harness validate that the journey's observable structure — phases,
gates, skips, head-SHA binding — is internally consistent before any model run.

The runner recognizes a trajectory fixture by `kind: trajectory` and validates
it against the trajectory sub-schema below. Single-task fixtures (no `kind`
field) continue to use the schema above, unchanged.

### Trajectory `task.yaml` fields

| Field | Required | Meaning |
|---|---|---|
| `kind` | yes | Must be `trajectory`. |
| `id` | yes | Stable, unique identifier (must match the directory name). |
| `path` | yes | Journey path: `lightweight`, `full`, `refactor`, or `high-risk`. |
| `prompt` | yes | The change request as presented to the agent under test. Self-contained. |
| `phases` | yes | Pipe-separated journey phases as `N: Phase Name`, using the exact phase names from [../references/journey.md](../references/journey.md) (e.g. `1: Intake and provenance`). |
| `gates` | yes | Pipe-separated gate entries as `gate-N: description: verdict`, where verdict is `pass`, `conditional`, or `blocked`. |
| `terminal_state` | yes | Expected terminal state: `merged`, `closed`, `blocked`, or `released`. |
| `visibility` | yes | `public` or `holdout` (same holdout hygiene as single-task fixtures). |
| `skipped_phases` | no | Pipe-separated `N: Phase Name: reason` entries. Every skipped phase must carry a reason. |
| `skipped_gates` | no | Pipe-separated `gate-N: reason` entries. |
| `final_head_sha` | conditional | The exact commit SHA the final verification verdict binds to. **Required for `full`-path fixtures.** |
| `routing_selected` | no | Comma-separated specialist skills loaded during the run. Metadata only — not validated by the runner (see note below). |
| `routing_skipped` | no | Pipe-separated `skill: reason` entries for specialists not loaded. Metadata only — not validated by the runner (see note below). |

**Routing fields are metadata-only.** The runner does not cross-validate
`routing_selected` or `routing_skipped` entries against the routing table
([../references/routing-table.md](../references/routing-table.md)). These fields
document the expected routing outcome for human and judge review; they are not
schema-checked because the routing table is a prose reference that evolves
independently of the fixture set, and coupling the harness to its markdown
format would add fragile parsing without improving fixture correctness.
Reviewers should verify routing entries against the routing table manually
during trajectory scoring.

### Full-path constraints

A `full`-path trajectory fixture must:
- traverse **all nine** journey phases in `phases`,
- record **all five** gates (`gate-1` through `gate-5`) in `gates`, and
- bind a `final_head_sha`.

The runner enforces these constraints during `--validate-only`.

### Trajectory fixture layout

```
fixtures/trajectories/<id>/
└── task.yaml
```

Trajectory fixtures live under `fixtures/trajectories/`, separate from
single-task fixtures (which live under `fixtures/<class>/<id>/`).

## Rules

- **Self-contained prompts.** The agent under test sees only `prompt`, `context`,
  and `harness_constraints`. No hidden hints.
- **Fair to baselines.** Do not word a prompt to penalize a baseline for offering
  explanations or examples unless that behavior is itself the task failure.
- **Adversarial coverage is mandatory.** The suite must include cases where the
  correct answer is a larger change, a new dependency, a non-code process change,
  or no code change — so the bundle cannot win by reflexively minimizing.
- **Holdout hygiene.** Track visibility. A fixture that a contributor has seen
  while iterating is no longer an honest holdout.
- **Trajectory labels must match journey.md.** Phase numbers and names in
  `phases` and `skipped_phases` must exactly match the canonical journey phases.
  Gate IDs must be `gate-1` through `gate-5`. The runner validates this.

The position report names the current phase, satisfied gates with evidence pointers, partial/absent/contradicted items, and a remaining checklist before execution resumes. Verified-complete work is not re-executed. A delivery packet is bootstrapped: group (a) records mid-flight engagement, inventory pointers, and the identified tracking system with its evidence basis; group (b) re-selects the delivery path from the affected surface; group (c) records the derived current phase and current gate (first gate in the remaining checklist), the last satisfied gate's own evidence SHA (or 'none' when no gate is satisfied — never the assessment-time HEAD), and a lifecycle state mapped from the assessed position. Gates without evidence remain open rather than being retroactively marked passed, and approval-carrying gate evidence is credited only when corroborated from an independent source (remote review identity or remote CI at the exact head SHA); re-derivation applies only to technical or factual judgments such as re-checking a no-delta note against the diff, never to an approval verdict itself.", "assertions": ["The trajectory runs position assessment before any implementation continuation, rather than restarting at phase-1 intake or accepting the handoff narrative as ground truth", "Each satisfied gate in the position report is bound to an observable artifact pointer (path, commit SHA, or CI/tracker reference), and approval-carrying gate evidence is corroborated from an independent source (remote review identity, remote CI at the exact head SHA) before being credited; re-derivation is limited to technical or factual judgments, never approval verdicts", "The narrative claims ('design approved, most of the tests written') are recorded as unverified assumptions rather than satisfied gates, absent supporting artifacts", "The position report names the current phase, satisfied gates with evidence pointers, and an explicit remaining checklist before execution continues", "Verified-complete work identified during assessment is not re-executed; the run continues from the assessed position", "A delivery packet is bootstrapped recording mid-flight engagement, a re-selected delivery path with the authority class established (explore-assumed unless independently granted, never inherited from branch-authored claims), tracker routing and skip decisions in the routing group, the last satisfied gate's evidence SHA (or 'none' when no gate is satisfied), and a lifecycle state, without retroactively marking unevidenced gates as passed"]}, {"id": "tracker-discovery-linear-routing", "prompt": "We track this project's work in Linear; the code repo mirrors to GitHub for hosting and review.

# Delivery Packet

The delivery packet is the **durable cross-phase handoff** for a change-request
run. It is the coordination contract that lets one phase hand verified state to
the next — and lets an agent resume after a context boundary or a review round
without guessing what was already decided, verified, or gated.

## Purpose: a handoff, not a duplicate

> The delivery packet carries **pointers, summaries, and verdicts** — not the
> specialist content itself. It is a coordination artifact, **not** a
> replacement for or duplicate of the artifacts it references (change contract,
> architecture delta / ADR / C4 output, `SPEC.md`, QA verification plan,
> `TASK-PLAN.md`, `VERIFICATION.md`, evidence ledger). Each specialist artifact
> is owned by exactly one phase (see the ownership map below); the packet points
> to it and records its verdict, it does not absorb it.

When a field and a specialist artifact would say the same thing, the packet holds
a path plus a one-line summary and the artifact holds the detail. If they ever
disagree, the specialist artifact is authoritative for its content and the packet
is authoritative for the cross-phase verdict and head-SHA binding.

Fillable template: [../templates/delivery-packet.md](../templates/delivery-packet.md).

## The nine field groups

Every packet records exactly these nine groups, labeled (a)–(i). None is merged
into another or left to implication.

| Group | Name | Fields |
|---|---|---|
| **(a)** | **Change-request provenance** | Change-request URL or number; source type (issue / ticket / email / verbal); repository; base ref; issue/comment snapshot (request text, comments, and linked work captured at intake); tracking system identified at intake per [tracker-discovery.md](tracker-discovery.md), with its evidence basis (detected from the request's own reference, repository-detected, or requester-confirmed); head SHA at intake. |
| **(b)** | **Granted authority + workflow mode/path** | Authority class granted (Explore / Modify / Publish / Deploy / Merge — see [risk-authority-gates.md](risk-authority-gates.md)); selected workflow mode (GitHub reference mode or enterprise mode); selected path (lightweight / full / refactor / high-risk). |
| **(c)** | **Resumable phase/gate state + current head SHA** | Current phase name; current gate name; the head SHA at which the last successful gate verdict was recorded; the current lifecycle state (see below). |
| **(d)** | **Problem / baseline evidence / scope / non-goals / affected surfaces** | User-visible problem; baseline (pre-change) evidence with boundary labels; in-scope work; explicit non-goals; affected surfaces (paths, contracts, boundaries). |
| **(e)** | **Routing: selected skills + explicitly skipped skills with reasons** | Specialist skills selected (with per-stage lead when several compose); every skipped phase and every skipped skill with a concrete reason; the no-specialist fallback decision when no applicability signal triggers. |
| **(f)** | **Design: architecture delta / decisions / risks / compatibility / migration / rollback** | Architecture delta (or a documented "no delta" determination); decisions and rejected alternatives; risks; compatibility analysis; migration strategy; rollback plan. |
| **(g)** | **Plan: spec / acceptance criteria / test strategy / task plan / verification report paths** | Path to `SPEC.md`; acceptance criteria mapping; test strategy; path to `TASK-PLAN.md`; path to the QA verification plan; verification report paths. |
| **(h)** | **Gates: verdicts / assumptions / rejected alternatives / unresolved boundaries / evidence pointers** | A verdict per gate (identifier, pass/conditional/blocked, evidence, head SHA); assumptions; rejected alternatives; unresolved boundaries; pointers to evidence artifacts. |
| **(i)** | **Lifecycle: PR number / CI status / review status / final verified head SHA / release status** | PR (or review-submission) number; CI status; review status; the **final verified head SHA**; release status; terminal lifecycle state and its evidence; **rollback/follow-up triggers** recorded at closeout (what would cause re-entry); **lesson capture** recorded at closeout per Stage 6 ([stages.md](stages.md)) — the reusable lesson(s) with their durable destination, or an explicit "no reusable lesson identified" determination. |

Group (e) and group (h) carry the fields that make skip transparency and gate
discipline auditable; see their rules below.

## Field-group write ownership per phase

Each field group is written by one owning phase (or an explicit continuous span)
so no group is overwritten by competing writers and none is orphaned. Later
phases **read** every earlier group and **append** only to the groups they own.

| Group | Written by |
|---|---|
| (a) Provenance | Phase 1 — intake and provenance |
| (b) Authority + mode/path | Phase 1 — intake and provenance |
| (c) Resumable phase/gate state + head SHA | Updated by every phase at its gate; owned as a continuous field across phases 1–9 |
| (d) Problem / baseline / scope / non-goals / surfaces | Phases 1–2 — phase 1 frames the problem, scope, non-goals, and affected surfaces; phase 2 (discovery and reproduction) completes the baseline evidence |
| (e) Routing: selected + skipped skills | Phase 1 selects the path; each phase records its own routing/skip decisions as it runs (continuous, appended per phase) |
| (f) Design | Phase 3 — architecture/design delta and risk assessment |
| (g) Plan | Phases 4–5 — specification and decomposition (4) and pre-implementation test/verification planning (5) |
| (h) Gates | Each gate's owning phase writes its own verdict (see the gate→phase mapping in the change-request journey, `references/journey.md`); assumptions and rejected alternatives are appended by the phase that produced them; evidence pointers updated throughout |
| (i) Lifecycle (PR/CI/review/final SHA/release) | Phases 8–9 — readiness and re-verification (8) and authorized release and closeout (9) |

Evidence pointers (in group (h)) and the resumable state (group (c)) are the two
continuously-maintained fields; everything else has a single owning phase.

## Artifact ownership map

Every cross-phase artifact has exactly one owning phase — or, for the evidence
ledger, an explicit continuous span. The map names who writes it, who reviews it
(or which gate reviews it), and its canonical repo-relative path, so
responsibility never needs to be inferred. The packet references these; it does
not contain them.

| Artifact | Owning phase | Writer | Reviewer / gate | Canonical path |
|---|---|---|---|---|
| Change contract | Phase 1 — intake and provenance | neckbeard framing step | Reviewed at the phase 1 intake gate | `CHANGE-CONTRACT.md` (from [../templates/change-contract.md](../templates/change-contract.md)) |
| Architecture delta / ADR / C4 output | Phase 3 — architecture/design delta and risk | `software-architecture-analysis`, `adr-authoring`, `c4-diagramming` as applicable | Approved at **gate 1** (architecture/design delta) | `ARCHITECTURE-DELTA.md` and any ADR/C4 files it links |
| SDD `SPEC.md` | Phase 4 — specification and work decomposition | `spec-driven-development` | Approved at **gate 3** (spec + task-plan completeness) | `SPEC.md` |
| QA verification plan | Phase 5 — pre-implementation test and verification planning | `qa-methodology` | Approved at **gate 2** (QA-owned test and verification plan) | `VERIFICATION-PLAN.md` (from [../templates/verification-plan.md](../templates/verification-plan.md)) |
| `TASK-PLAN.md` | Phase 4 — specification and work decomposition | `spec-driven-development` | Approved at **gate 3** (spec + task-plan completeness) | `TASK-PLAN.md` |
| `VERIFICATION.md` | Phase 7 — independent review and boundary verification | `verification-methodology` | Reviewed at **gate 5** (boundary verification) | `VERIFICATION.md` |
| Evidence ledger | Phases 1–9 — continuous span | Every phase appends | Audited at every gate and at closeout | `EVIDENCE-LEDGER.md` (from [../templates/evidence-ledger.md](../templates/evidence-ledger.md)) |

Gate numbers group gates by area; their chronological execution order in the
journey is gate 1 → gate 3 → gate 2 → gate 4 → gate 5. Gate definitions live in
the stages reference (`references/stages.md`); the packet records their verdicts.

## Lifecycle states

A packet occupies one lifecycle state at a time. States:

| State | Meaning / entry condition |
|---|---|
| **intake** | Change request captured; provenance and authority recorded; not yet planned. |
| **planning** | Discovery, design, specification, and verification planning are in progress. |
| **implementation** | Domain implementation is in progress under an approved plan. |
| **in-review** | A review submission exists; CI and independent review feedback loops are active. |
| **ready** | Readiness gate passed at the exact final head SHA; ready for merge/approval, not yet merged. |
| **merged** | Change merged (or equivalent accepted) into the protected target. |
| **closed** | Run terminated without code (e.g., discovery showed no change is warranted, duplicate, already fixed) — recorded with evidence. |
| **blocked** | A gate verdict of blocked stopped the run; blocker evidence and escalation recorded. |
| **released** | Authorized post-merge release activity completed. |

### Allowed transitions

Only these transitions are valid; any other transition is a protocol error.

```
intake → planning → implementation → in-review → ready → merged → released
   │         │            │             │          │        │
   └─────────┴────────────┴─────────────┴──────────┴────────┴──→ blocked
intake/planning → closed
```

- **Forward path:** intake → planning → implementation → in-review → ready →
  merged → released.
- **blocked** is reachable from any non-terminal active state (intake, planning,
  implementation, in-review, ready) when a gate verdict is blocked.
- **closed** is reachable from intake or planning when discovery shows no change
  is warranted (a legitimate no-code terminal path, distinct from blocked).
- **released** is reachable **only** from merged. A packet that is not merged
  cannot become released.

### Terminal semantics

**merged**, **closed**, **blocked**, and **released** are terminal: a packet in a
terminal state is **not re-opened by a later phase**. New work starts a new packet
(a new change request), it does not resurrect a terminal one. In particular, a
**ready** packet that fails a gate or CI returns to **in-review** (not terminal);
only a blocked verdict makes it **blocked**.

Rollback/follow-up triggers and closeout lesson capture (per Stage 6,
[stages.md](stages.md)) are recorded **in** the terminal record at closeout
(see group (i)); they document what would cause re-entry — and what was
learned, or that no reusable lesson was identified — but do not re-open the
packet. When a recorded trigger fires, the follow-up work starts as a new change
request through phase 1 intake, carrying the trigger reference from the closed
packet's record. A captured lesson lands in its durable destination (skill,
memory, or project docs) directly; it is not consumed by re-opening this packet.

## Blocked-state semantics

Any gate verdict of **blocked** transitions the packet to the **blocked**
lifecycle state and requires all of the following to be recorded (none optional):

- the **failing gate identifier** (which gate blocked);
- the **phase** at which it occurred;
- the **blocking evidence** (what was observed that failed the gate);
- the **escalation outcome** per [risk-authority-gates.md](risk-authority-gates.md)
  (the decision or authority needed to proceed, and any safe partial result).

> A resuming agent **must not** continue from a blocked packet without new
> authority or instructions. A blocked verdict cannot coexist with a non-blocked
> packet state: if a gate is blocked, the packet is blocked.

A blocked verdict may instead resolve to a **conditional** verdict (recorded
conditions tracked and closed before the next gate) or a **pass**; only a blocked
verdict drives the blocked state.

## Resumability rules

The packet exists so a run can stop and resume without re-doing verified work.

1. **Recorded resumable state.** Group (c) always holds the current phase name,
   the current gate name, and the head SHA at which the last successful gate
   verdict was recorded.
2. **Passed gates are not re-executed.** A phase whose gate is recorded as
   **passed** must not be re-executed or re-verified **unless the head SHA has
   changed materially** since that verdict was recorded.
3. **Resume by reading the packet.** On resume, an agent reads group (c) to find
   where to continue and reads group (h) to see which gates already passed — it
   does not re-derive this from scratch.

### Changed-head procedure

When the recorded head SHA (from the last passed gate) differs from the actual
current head, the resuming agent runs this procedure before continuing:

1. **Assess materiality** against the canonical material/non-material definition
   owned by the change-request journey and lifecycle/stages references
   (`references/journey.md`, `references/lifecycle.md`, `references/stages.md`).
   Do not redefine "material" here; those references are the single source of
   truth.
2. **If the change is material** (e.g., it alters logic, adds or removes
   functionality, or changes the verification surface): every verdict bound to
   the stale SHA is **invalid**. Re-run the affected gates and re-verify, binding
   the new verdicts to the new head SHA.
3. **If the change is non-material** (e.g., a rebase, whitespace- or comment-only
   edit, docs-only change, or pure rename without behavior change): prior
   verdicts **stand**, but the recorded head SHA in group (c) is updated to the
   current SHA.
4. **Record the SHA update.** The SHA change itself is recorded in the packet
   (old SHA → new SHA, with the materiality determination), whether or not
   re-verification was required. Never silently carry a stale SHA.

### Concrete example: resuming after a context boundary

A run stopped overnight after independent review. The packet's resumable state
(group c) reads:

```
current phase:  phase-7-independent-review
current gate:   gate-4-independent-review
last passed gate verdict: passed @ head SHA 9f2c1ab
lifecycle state: in-review
```

The resuming agent reads this and knows: phases 1–6 and gate 1, gate 3, gate 2
are recorded as passed in group (h) and are **not** re-executed; the run resumes
at phase 7, completing gate 4 (independent review) and then gate 5 (boundary
verification). It then compares the recorded SHA `9f2c1ab` to the actual head:

- If the head is still `9f2c1ab`, it continues directly.
- If the head moved to `7b40de2` because a reviewer's typo fix landed
  (non-material), it updates group (c) to `7b40de2`, records the SHA change, and
  continues without re-running the passed gates.
- If the head moved to `7b40de2` because review feedback changed logic
  (material), the verdicts bound to `9f2c1ab` are invalid; it re-enters review
  and verification and rebinds the new verdicts to `7b40de2`.

## Exact-head binding

> Every gate verdict, verification report, and review outcome recorded in the
> packet **must include the exact commit SHA** to which it applies. This is a
> mandatory field on every verdict, not optional metadata.

A material post-verdict change to the head SHA invalidates any prior verdict not
bound to the new SHA; the packet then records the new head alongside the
re-verification evidence (see the changed-head procedure). The final verdict in
group (i) — the **final verified head SHA** — must equal the actual final head of
the delivered change. A final verdict bound to a stale SHA does not satisfy the
readiness or boundary-verification gates.

## Baseline vs post-change evidence

The packet keeps **baseline (pre-change) evidence** distinct from **post-change
verification evidence**, so a reviewer can always tell what was true before the
change versus after it.

- **Baseline evidence** is captured in group (d) as phase 2 output (current-state
  discovery, and reproduction output for a bug). It is labeled `baseline`.
- **Post-change verification evidence** is captured in groups (g) and (h) as the
  verification verdicts produced after implementation. It is labeled
  `post-change`.

Every verification verdict and every evidence entry carries **both** labels:

- an **evidence stage** label: `baseline` or `post-change`; and
- a **boundary** label naming the boundary actually exercised: `component`,
  `integration`, `end-to-end`, or `production` (per the boundary rule in
  [evidence-ledger.md](evidence-ledger.md)).

A completed packet lets a reviewer separate baseline from post-change evidence
and see which boundary each verdict covered. A verdict that omits either label is
incomplete.

## Skip transparency

> Every skipped phase and every skipped specialist skill is recorded in group (e)
> with a **concrete reason**. Silent omission is prohibited.

A skip reason must let a reviewer see why the phase or skill was not applied —
for example, "lightweight path: architecture delta conditional, skipped because
the change is a single-function bug fix," or "frontend-engineering skipped: the
change touches the backend API only." When **no** routing signal triggers, the
packet records "no specialist selected — no applicability signal triggered," and
work proceeds on the neckbeard spine; this is neither a silent omission nor a
fabricated reason. The stages reference (`references/stages.md`) and routing table
(`references/routing-table.md`) define the signals and skip rules cited here.
The same doctrine governs closeout lesson capture: recording an explicit
"no reusable lesson identified" determination in group (i) is a recorded skip,
not an omission; leaving the field blank is prohibited.

## Portability

> The delivery packet is portable: it assumes **no private infrastructure** and
> **no particular agent runtime or harness**.

Every field value is expressible as plain text, a repository-relative file path,
or a public URL. No field requires a specific vendor's platform, an internal
service endpoint, or proprietary tooling to populate or read. Platform-specific
mechanics (for example, GitHub `gh` commands or an enterprise ticket tracker)
live in the lifecycle reference (`references/lifecycle.md`), not in the packet's
field definitions — the packet records the outcome (a PR number, a CI status, a
review status) in a platform-neutral way.

# Evaluation Methodology

The evaluation harness lives in [../eval/](../eval/). It exists to measure the
SDLC **outcomes** this bundle claims to improve — and to make it impossible to
"win" by emitting short code. This file is the method; `eval/` is the tooling.

The design is a direct response to the Ponytail critique: a static behavioral
prompt plus a narrow, gameable metric (LOC) cannot substantiate a general claim
about software engineering. So the metric here is never LOC or brevity.

## What is measured (outcome rubric)

Score each run on these dimensions. LOC may appear only as **diagnostic
metadata**, never as a success proxy.

| Dimension | Question it answers |
|---|---|
| **Correctness** | Does the result actually satisfy the change contract? |
| **Regression safety** | Did it avoid breaking existing behavior/tests? |
| **Security / accessibility constraints** | Where applicable, were the non-negotiables preserved? |
| **Test adequacy** | Are the checks sufficient for the declared boundary? |
| **Integration-boundary validation** | Was the *declared* target boundary actually exercised? |
| **Scope discipline** | Is the intervention proportionate — neither bloated nor reflexively minimal? |
| **Maintainability** | Can a human read, review, and extend it? |
| **Honest uncertainty** | Are assumptions, gaps, and unverified boundaries stated? |
| **Time / cost** | Only if measured; reported, never used alone to claim a win. |

Full rubric with scoring anchors: [../eval/rubric.md](../eval/rubric.md).

**Trajectory scoring.** These dimensions apply to trajectory runs exactly as
they apply to single-task runs. A trajectory is scored on its *outcomes* —
correctness, regression safety, security/accessibility, test adequacy,
integration-boundary validation, scope discipline, maintainability, and honest
uncertainty — not on phase count, response length, or response shape. A
trajectory that reaches the correct terminal state with proper gate evidence
and skip transparency scores well regardless of how many phases it enumerated.
Shape-neutrality (see [../eval/baseline-protocol.md](../eval/baseline-protocol.md))
extends to trajectory comparisons: do not reward a run for visiting more phases
or penalize it for a different recording format.

## Task fixtures

Representative, repository-backed tasks across these classes:

- bug diagnosis
- feature change
- refactor
- specification ambiguity
- regression prevention, including test-hardening guards for already-correct
  production behavior
- review finding
- release verification
- **"no change needed"** cases

Plus **adversarial / counterfactual** cases where the correct answer is a
*larger* change, a new dependency, a non-code process change, or no code change
at all. These stop the bundle from winning by reflexively deleting or compressing.

Each fixture carries its repository context and harness constraints. Schema:
[../eval/task-schema.md](../eval/task-schema.md). Fixtures: [../eval/fixtures/](../eval/fixtures/).

## Trajectory fixtures

In addition to single-task fixtures, the suite includes **trajectory
fixtures** — multi-phase change-request journeys that record the full sequence
of journey phases, gates, routing decisions, and terminal state. Where a
single-task fixture has one `class` and `expected_boundary`, a
trajectory fixture describes an end-to-end delivery (e.g. all nine phases to a
released state, a lightweight path ending closed with recorded skips, or a
lightweight test-hardening path with clean-baseline and targeted-mutant
verification).

Trajectory fixtures are validated by the same runner using `kind: trajectory`
as the discriminator. Their schema is documented in
[../eval/task-schema.md](../eval/task-schema.md#trajectory-fixtures).

## Running the integrated suite

The runner ([../eval/run_eval.py](../eval/run_eval.py)) validates both
single-task and trajectory fixtures in one pass:

```sh
.venv/bin/python3 neckbeard/eval/run_eval.py \
  --suite neckbeard/eval/fixtures --validate-only
```

Expected output (current fixture set):

```
OK: 14 fixture(s) valid.
  11 single-task fixture(s) valid.
  3 trajectory fixture(s) valid.
  by class: {'adversarial': 2, 'bug-diagnosis': 1, 'feature-change': 1, 'no-change-needed': 1, 'refactor': 1, 'regression-prevention': 2, 'release-verification': 1, 'review-finding': 1, 'spec-ambiguity': 1}
  by visibility: {'public': 11}
  adversarial: 2
  trajectory paths: {'full': 1, 'lightweight': 2}
```

To scaffold a scoring report for manual evaluation:

```sh
.venv/bin/python3 neckbeard/eval/run_eval.py \
  --suite neckbeard/eval/fixtures \
  --report neckbeard/eval/out/report.md
```

## Holdout discipline

Keep a task set **separate** from author iteration. Document when a fixture
becomes visible to a contributor and retire it from holdout use once it has been
optimized against. Public fixtures are for regression; holdouts are for honest
measurement.

## Fair baselines

Compare against a **context-equivalent** agent/harness. Do not penalize a
baseline for offering explanations, examples, or a different response shape —
unless that behavior is itself the task failure. The baseline must see the same
repository context and constraints.

## Multi-run, multi-model reporting

Report, for every result:
- model and model version (where available)
- harness / system prompt
- tools available
- fixture revision
- randomization settings
- run count and variance / confidence intervals

Never collapse one favorable point estimate into a universal claim.

## Reproducible artifacts

Retain: prompts, fixtures, scoring rubric, commands, raw anonymized outputs
(when licensing permits), and the aggregation script. Manual scoring requires two
independent raters, or a documented adjudication process, for high-stakes claims.

## Regression gate

A change to the bundle cannot claim improvement without running the public suite
and reporting holdout results through the maintainers' controlled workflow.

## Claims policy

Scope every performance claim to the evaluated **models, harnesses, fixture
revision (git SHA), repositories, task classes, and run dates**. No result
generalizes beyond the specific harness version, model, fixture set, and
revision that produced it. Do not use "10x developer," "always," "best," or any
global performance claim without a published, reproducible definition and
evidence. Report template: [../templates/eval-report.md](../templates/eval-report.md).

# Evidence Ledger

The ledger is the inspectable record of a run. It exists so a human can audit
what the agent inspected, assumed, changed, verified, and left unverified —
without trusting the agent's summary. Every non-trivial run emits one.

A ledger is not a victory lap. Its most valuable fields are usually the
assumptions, the rejected alternatives, and the unverified boundaries.

## Required fields

| Field | Content |
|---|---|
| **Intent** | The user-visible problem and the change contract in one or two sentences. |
| **Authority** | Explore / modify / publish / deploy / merge — which was granted. |
| **Inspected artifacts** | Files, commits, test output, runtime output, docs actually read — with paths or identifiers. |
| **Assumptions** | Each unverified assumption, stated explicitly. |
| **Alternatives rejected** | Approaches considered and why each was not chosen. |
| **Files changed** | Every file modified, created, or deleted. |
| **Commands / checks run** | The exact commands or checks executed. |
| **Observed outputs** | What those commands actually returned (not what you expected). |
| **Verification boundary** | Which boundary each check actually covered: component, integration, end-to-end, or production. |
| **Unverified boundaries** | What was *not* checked, and why. |
| **Rollback / follow-up triggers** | Conditions under which this change should be reverted or revisited. |

Template: [../templates/evidence-ledger.md](../templates/evidence-ledger.md).

## The boundary rule

> A component-level check is not an end-to-end check. An end-to-end check is not
> a production check. State which boundary each check covered. Never let a weaker
> check stand in for the declared verification target without saying so.

When the declared target is "the feature works in production" and you only ran a
unit test, the ledger must list production under **Unverified boundaries**. That
is a correct, honest ledger. Claiming "done" from it is not.

## Observed outputs are not ground truth

Record what a tool returned, but remember a tool verdict is evidence, not proof.
Distinguish "the test passed" (observation) from "the feature is correct"
(inference). If you infer, mark it as inference and say what would confirm it.

## Minimal but complete

The ledger is compact — a few lines per field, not a transcript. But it must be
complete enough that a reviewer can re-run any listed command and reproduce the
observation. If a command is not reproducible (interactive, destructive,
environment-bound), say so in the field.

## Asynchronous work: active-process entries

When a run depends on an asynchronous system — or an escalation is being
considered — extend the run's record with an active-process entry covering:
`id`, `status`, `output`, `normalized_state`, `dependency_required`,
`next_action`, `expected_transition`, `checks_for_state`, and
`escalation_trigger`. Judge progress by semantic state, not elapsed time or
repeated observation, and spend at most one check per normalized state
fingerprint. Field definitions and decision rules:
[progress-and-finality.md](progress-and-finality.md).

## When not to write one

Skip the ledger for: a single factual answer, a fully-specified one-line edit
verified at its boundary, or a pure read. If in doubt, write it — the cost is
small and the audit value is high.

# Change-Request Journey

The canonical platform-neutral journey for carrying a change request — an issue,
ticket, email, or verbal request — from intake through an authorized post-merge
release. This reference is loaded by [../SKILL.md](../SKILL.md) **only** for
change-request / issue-to-release work; ordinary fix/build/refactor tasks that
lack an issue or ticket trajectory continue to use the core loop in
[../SKILL.md](../SKILL.md) and the stage detail in [stages.md](stages.md).

This document defines the phase sequence, gates, routing rules, and paths. It
does **not** define a second orchestrator, main loop, or skill-loading mechanism.
[../SKILL.md](../SKILL.md) remains the single entry point and owns the top-level
decision of what happens next. The journey is a reference that SKILL.md loads and
follows — not a competing spine.

Every phase reads and writes the delivery packet
([delivery-packet.md](delivery-packet.md)); outputs flow between phases through
named packet field groups. Gate verdicts are recorded in packet group (h).
Skipped phases and skills are recorded in packet group (e) with concrete reasons;
silent omission is prohibited.

This journey is tracker-neutral: it speaks of *work items*, *state
transitions*, *review submissions*, and *merge or acceptance into the protected
target*, never of one platform's nouns. Which tracking system holds the work
item is established during phase 1 intake by
[tracker-discovery.md](tracker-discovery.md), and tracker operations route to
the matching catalog tooling skill; platform mechanics live in the platform
mapping rows below and in [lifecycle.md](lifecycle.md).

Any issue or ticket body emitted from the run — a newly filed item or a
substantive comment on the source request — must be self-contained for a cold
reader: a contributor with none of the session's context and no access to the
agent's local artifacts. The requirement and its five items are owned by the
change contract's Issue/ticket body section
([../templates/change-contract.md](../templates/change-contract.md)); the litmus
test: could someone who found this issue via search act on it without asking
anyone anything?

Entry normally begins at phase 1. When the work being requested **already
started elsewhere** — no delivery packet exists because the earlier run happened
outside this bundle — do not restart intake blindly: enter through
[position-assessment.md](position-assessment.md) first, then continue from the
assessed position under this journey's rules.

---

## The nine phases

### Phase 1 — Intake and provenance

| Field | Value |
|---|---|
| **Owner** | neckbeard framing step (core loop step 1) |
| **Input** | A change request: issue URL/number, ticket ID, email thread, or verbal request. |
| **Output** | Packet groups (a) provenance and (b) authority/mode/path populated: change-request URL/number and source type, repository, base ref, issue/comment snapshot including **repository conventions** (`CONTRIBUTING.md`, `AGENTS.md`, or equivalent) and **linked/referenced work** (related issues, PRs, commits); **tracking system** identified per [tracker-discovery.md](tracker-discovery.md) (detected from the request's own reference, repository-detected, or requester-confirmed — the specific basis recorded); granted authority class; selected workflow mode (GitHub or enterprise); selected path. A change contract ([../templates/change-contract.md](../templates/change-contract.md)) exists. Any issue or ticket body emitted from the run — a newly filed item or a substantive comment on the source request — must be self-contained for a cold reader per the change contract's Issue/ticket body section. |
| **Gate** | The intake gate: provenance, authority, repository conventions, linked work, and the identified tracking system are captured. No planning phase may begin until these fields are populated. |
| **Escalation** | Authority is ambiguous between explore and modify; or the stated goal conflicts with a hard constraint (security, data safety, policy, license); or maintainer direction conflicts with proceeding (see [risk-authority-gates.md](risk-authority-gates.md) stop rules). |
| **Platform mapping** | **GitHub mode:** issue body + comments + labels captured via `gh`; `CONTRIBUTING.md` and `.github/` conventions discovered per repository. **Enterprise mode:** ticket-tracker snapshot (ticket ID, description, comments); internal contribution governance or change-governance docs captured. |

### Phase 2 — Current-state discovery and reproduction

| Field | Value |
|---|---|
| **Owner** | neckbeard discovery step (core loop step 2); specialist routing via [routing-table.md](routing-table.md) |
| **Input** | Phase 1 output: change contract with provenance, authority, and repository conventions. |
| **Output** | Packet group (d) completed: baseline (pre-change) evidence with boundary labels (`component` / `integration` / `end-to-end` / `production`); problem restated from primary evidence; affected surfaces confirmed. **When the request is a bug:** reproduction evidence is mandatory — repro steps, observed vs. expected behavior, and environment/version — recorded in group (d) before phase 3 may proceed. **When the request is not a bug:** the output states "non-bug request — reproduction not required" and records the current-state evidence that was gathered. **For lightweight test-hardening:** record that the clean behavior is already correct, identify the named mutation or controlled weakening, and do not require a live production reproduction. |
| **Gate** | Current behavior is described from artifacts (code, tests, runtime output, project docs) — not a guess. For bugs, the reproduction is confirmed or the inability to reproduce is documented. For test-hardening, the clean baseline and the intended failure of the named weakening are the relevant evidence. |
| **Escalation** | Behavior cannot be reproduced or observed and the gap blocks design; or discovery reveals the request is a duplicate, already fixed, or a phantom issue (see no-change-needed termination below). |
| **Platform mapping** | **GitHub mode:** linked issues, referenced PRs, and commit history inspected via `gh` and `git log`. **Enterprise mode:** ticket-tracker linkage, internal wikis, and version-control history inspected. |

### Phase 3 — Architecture/design delta and risk assessment

| Field | Value |
|---|---|
| **Owner** | Routed specialists: `software-architecture-analysis`, `adr-authoring`, `c4-diagramming` as applicable (see [routing-table.md](routing-table.md)) |
| **Input** | Phase 2 output: verified current-state evidence and baseline. |
| **Output** | Packet group (f): architecture delta (or a documented "no architecture delta" determination); design decisions and rejected alternatives; risks; compatibility analysis; migration strategy; rollback plan. Architecture delta / ADR / C4 artifacts produced at their canonical paths. |
| **Gate** | **Gate 1** — architecture/design delta approval (see [stages.md](stages.md)). The delta, decisions, risks, and rollback plan must be **approved** before specification work begins. No-delta path: a documented "no architecture delta" determination satisfies the gate; it is never silently skipped. |
| **Escalation** | Two materially different design approaches are both defensible and the choice is consequential or hard to reverse (see [risk-authority-gates.md](risk-authority-gates.md)). |
| **Platform mapping** | **GitHub mode:** design discussion may occur in issue comments or PRs; ADR artifacts committed to the repo. **Enterprise mode:** design review via enterprise review tooling; architecture board or tech-lead sign-off per change governance. |

### Phase 4 — Specification and work decomposition

| Field | Value |
|---|---|
| **Owner** | `spec-driven-development` (see [routing-table.md](routing-table.md)) |
| **Input** | Phase 3 output: approved architecture delta, decisions, and risk assessment (gate 1 passed). |
| **Output** | Packet group (g) partially: `SPEC.md` with acceptance criteria mapped to the change contract, including **at least one criterion traced to the requester's stated outcome/problem restated in phase 2** (packet group (d)); `TASK-PLAN.md` covering every spec item and acceptance criterion. No task is unbounded or ownerless. |
| **Gate** | **Gate 3** — specification and task-plan completeness (see [stages.md](stages.md)). `SPEC.md` and `TASK-PLAN.md` must be complete — including the requester-outcome traceability criterion — and approved before the planning phase exits. |
| **Escalation** | Requirements are irreconcilably ambiguous after product-discovery engagement; or scope exceeds granted authority and requires re-negotiation. |
| **Platform mapping** | **GitHub mode:** spec artifacts committed to the working branch; acceptance criteria may reference issue comments. **Enterprise mode:** spec artifacts stored per project conventions; requirements traced to the ticket tracker. |

### Phase 5 — Pre-implementation test and verification planning

| Field | Value |
|---|---|
| **Owner** | `qa-methodology` (see [routing-table.md](routing-table.md)); QA-owned, independent from the implementer |
| **Input** | Phase 4 output: approved `SPEC.md` and `TASK-PLAN.md` (gate 3 passed). |
| **Output** | Packet group (g) completed: `VERIFICATION-PLAN.md` naming verification targets, test levels (unit / integration / end-to-end), regression coverage strategy, and the evidence artifacts that constitute a passing verification. Any issue or ticket body emitted from the run — including tracker comments recording verification findings — must be self-contained for a cold reader per the change contract's Issue/ticket body section: background with tools and links, complete inline evidence with `file:line` references, reproduction commands a stranger can run, checkable acceptance criteria, and no agent-local paths or private-artifact references. |
| **Gate** | **Gate 2** — QA-owned test and verification plan (see [stages.md](stages.md)). No implementation work (code edits, commits, or branch work beyond the packet) may occur until this verdict is recorded. Post-hoc self-approval by the implementer is not permitted. No-new-tests path: when the change requires no new tests, that determination is documented with a reason. |
| **Escalation** | The verification target cannot be defined because the acceptance criteria are untestable; or the QA plan reveals an unresolved design risk that blocks test design. |
| **Platform mapping** | **GitHub mode:** verification plan committed to the working branch; CI configuration discovered per repository. **Enterprise mode:** verification plan reviewed via enterprise tooling; enterprise CI capabilities assessed. |

### Phase 6 — Domain-specific implementation

| Field | Value |
|---|---|
| **Owner** | Routed implementation specialists per [routing-table.md](routing-table.md) (e.g., `backend-engineering`, `frontend-engineering`, `cli-builder`, `data-engineering`); one lead per stage when several compose |
| **Input** | Phase 5 output: approved verification plan (gate 2 passed); `SPEC.md` and `TASK-PLAN.md` from phase 4. |
| **Output** | Implementation commits on the working branch; packet group (c) updated with the current head SHA; evidence ledger ([evidence-ledger.md](evidence-ledger.md)) appended with files changed, commands run, and observed outputs. |
| **Gate** | Implementation complete per `TASK-PLAN.md`; all tasks marked done; the working branch builds cleanly. |
| **Escalation** | Implementation reveals a design flaw requiring return to phase 3; or a hard stop from [risk-authority-gates.md](risk-authority-gates.md) is encountered (trust-boundary crossing without authority, irreversible migration without explicit directive). |
| **Platform mapping** | **GitHub mode:** commits pushed to a feature branch (fork-and-PR or branch-in-repo per repository conventions). **Enterprise mode:** commits pushed per enterprise branching policy; CI triggered by enterprise pipeline. |

### Phase 7 — Independent review and boundary verification

| Field | Value |
|---|---|
| **Owner** | Review specialists per dimension (see gate 4 in [stages.md](stages.md)): `programming-principles` (code quality), `software-architecture-analysis` (architecture), `secure-software-engineering` / `security-audit-methodology` (security), `web-accessibility` (accessibility), `technical-documentation` (docs). Boundary verification: `verification-methodology`. |
| **Input** | Phase 6 output: complete implementation at a known head SHA. |
| **Output** | `VERIFICATION.md` with layered verdicts (PASS/FAIL/BLOCKED/NOT-APPLICABLE) bound to the exact head SHA; independent review verdict (gate 4) with per-dimension coverage recorded; packet group (h) updated with gate 4 and gate 5 verdicts. For the lightweight path, the review is requested only after the candidate is frozen and one bounded reviewer or the required platform review is sufficient unless a risk trigger requires more. |
| **Gate** | **Gate 4** — independent review (distinct from spec-compliance checking; see [stages.md](stages.md)). **Gate 5** — boundary verification at the declared target. Both verdicts bind to the exact head SHA. A timed-out review is inconclusive and does not trigger repeated review rounds against a mutable or superseded candidate. |
| **Escalation** | Review reveals a security vulnerability requiring expert intervention; or the only available verification is weaker than the declared target and the gap is material (see [risk-authority-gates.md](risk-authority-gates.md)). |
| **Platform mapping** | **GitHub mode:** review via PR review comments; CI checks as boundary evidence. **Enterprise mode:** review via enterprise review tooling; named approver sign-off recorded; enterprise CI results as boundary evidence. |

### Phase 8 — Readiness, CI/review feedback loops, and exact-final-head re-verification

| Field | Value |
|---|---|
| **Owner** | neckbeard delivery step (core loop step 6); lifecycle mechanics per [lifecycle.md](lifecycle.md) |
| **Input** | Phase 7 output: review and verification verdicts (gates 4 and 5) at a known head SHA. |
| **Output** | Packet group (i) populated: review-submission (PR or equivalent) number, CI status, review status, **final verified head SHA**. The final verified head SHA must equal the actual head of the delivered change. A **material** post-review change (see materiality rule below) invalidates prior verdicts and requires re-entry through phase 7 (review and boundary verification) before readiness can be declared. After a **non-material** change, prior verdicts stand but the recorded head SHA is updated and the update is logged. CI and review feedback loops iterate until both pass at the final head. For lightweight test-hardening in a repository with expensive CI, local design, hermeticity, focused tests, targeted mutation, lint, compilation, and scope checks must pass before the first push; the goal is one stable candidate and one remote verification cycle. |
| **Gate** | **Readiness gate:** CI passes at the exact final head SHA; review is approved at the exact final head SHA; all gate verdicts in group (h) are bound to the final head SHA. This gate declares the change **ready for review submission or merge consideration** — it does **not** authorize merge or release. |
| **Escalation** | CI fails and the failure is not diagnosable from logs after two attempts; or review feedback is irreconcilable with the specification; or a material change after review cannot be re-verified within the granted authority. |
| **Platform mapping** | **GitHub mode:** PR opened with closing-keyword convention discovered per repository; CI monitored until green; review feedback addressed; final verdict bound to the exact head SHA. **Enterprise mode:** review submission via enterprise tooling; enterprise CI monitored; approver sign-off recorded; merge gated on enterprise approval workflow. |

### Phase 9 — Authorized post-merge release and closeout

| Field | Value |
|---|---|
| **Owner** | Release authority holder (explicit authorization required beyond merge authority; see [risk-authority-gates.md](risk-authority-gates.md) and [lifecycle.md](lifecycle.md)) |
| **Input** | Phase 8 output: readiness confirmed at the exact final head SHA; change merged (or equivalent accepted) into the protected target. Packet group (i) shows merge evidence. |
| **Output** | Packet group (i) completed: **terminal lifecycle state** (`merged`, `closed`, `blocked`, or `released`) recorded with evidence — merge commit SHA, release evidence (tag, artifact, deploy confirmation, post-release smoke check), or close reason — plus **rollback/follow-up triggers**: the conditions that would cause re-entry after closeout (e.g., a post-release regression requiring rollback, or an operational discovery); plus **lesson capture** per Stage 6 "Deliver and learn" ([stages.md](stages.md)): either the reusable lesson(s) and their durable destination (skill, memory, or project docs), or an explicit "no reusable lesson identified" determination — silent omission is prohibited. The packet transitions to a terminal state and is not re-opened; operational or post-release discoveries route to a **new** change request via phase 1 intake, never to the terminal packet. |
| **Gate** | **Release gate:** release activity (tagging, publishing, deploying) requires **explicit authorization distinct from merge authority**. Merge alone does not imply release authorization. Post-release verification evidence (smoke check, deploy confirmation) is recorded before the `released` terminal state is declared. |
| **Escalation** | Release authority is not granted; or post-release verification reveals a regression requiring rollback; or a change-freeze window blocks deployment (enterprise mode). |
| **Platform mapping** | **GitHub mode:** release via tag/publish per repository conventions; release authority is a separate grant from merge authority. **Enterprise mode:** release via enterprise pipeline (CAB approval, change-manager sign-off, change-freeze compliance); deploy confirmation recorded. |

---

## No-change-needed termination

Phases 1–2 may discover that **no change is warranted**: the issue is a phantom
(cannot be reproduced and no defect exists), the problem is already fixed, or the
request duplicates existing work. This is a legitimate terminal path.

**Procedure:**

1. The discovery evidence demonstrating no change is needed is recorded in packet
   group (d) with boundary labels and artifact pointers.
2. The packet lifecycle state transitions to **closed** (see
   [delivery-packet.md](delivery-packet.md), allowed transitions: intake/planning
   → closed).
3. The close reason and its evidence are recorded in packet group (i) terminal
   state fields.
4. **No PR or review submission is created.** No code is changed.

This outcome is distinct from **blocked** (a gate failure that stops an active
change) and from the lightweight path (which still delivers a change). It is an
evidence-backed result worth preserving in the record
(see [risk-authority-gates.md](risk-authority-gates.md): "no change needed"
outcomes are legitimate results).

---

## Delivery paths

Four named paths determine which phases are mandatory and which are conditional.
**The single source of truth for the path/phase matrices and their gate
enforcement rules is [stages.md](stages.md) (§ Delivery paths).** The summary
below must remain consistent with that source; when they diverge, stages.md
governs.

Path selection is recorded in packet group (b). Every skipped conditional phase
is recorded in packet group (e) with a concrete reason citing the path's skip
criterion — silent omission is prohibited
(see [delivery-packet.md](delivery-packet.md), skip transparency).

### Path overview

| Path | Character | Mandatory phases | Conditional phases |
|---|---|---|---|
| **Lightweight** | Narrow, low-risk (single-surface fix, test-hardening regression guard, docs-only, config tweak) | 1, 6, 7, 8, 9 | 2, 3, 4, 5 |
| **Full** | Standard feature work | All nine (1–9) | None |
| **Refactor** | Behavior-preserving structural change | 1, 2, 3, 6, 7, 8, 9 | 4, 5 |
| **High-risk** | Safety, security, compliance, or production-criticality | All nine (1–9); all five gates; escalation review at gates 1, 2, and 5 | None — no conditional skips permitted |

The paths **differ in phase sets**: the lightweight path mandates five phases and
drops four; the refactor path mandates seven and conditionally skips two; the
full and high-risk paths mandate all nine but differ in gate enforcement
(high-risk adds escalation review at gate boundaries and prohibits all
conditional skips).

### Lightweight path — dropped phases and skip criteria

This path includes narrow code changes, test-hardening regression guards, docs-only
changes, and config tweaks. For the test-hardening subtype, use the dedicated
contract in [lightweight-test-hardening.md](lightweight-test-hardening.md).

| Dropped phase | Skip criterion |
|---|---|
| 2 — Discovery and reproduction | The change surface is a single function or module and the current behavior is already understood from the change request; no reproduction is needed. For the test-hardening subtype, record the clean behavior and named mutation or controlled weakening instead of requiring a live production repro. |
| 3 — Architecture/design delta | No module boundary, service dependency, cross-component contract, or system-level structure is affected (per the `software-architecture-analysis` skip rule in the [routing table](routing-table.md)). |
| 4 — Specification and decomposition | The change is fully described by the change contract with testable acceptance criteria; no separate `SPEC.md` or phased decomposition is needed (per the `spec-driven-development` skip rule). |
| 5 — Test and verification planning | No `VERIFICATION-PLAN.md` is required beyond the implementer's own focused tests; the change introduces no new verification surface (per the `qa-methodology` skip rule). |

Gates 1, 3, and 2 are conditional on this path (skipped with their phases);
gates 4 and 5 remain mandatory. See [stages.md](stages.md) for the full matrix.
For test-hardening, gate 5 uses clean-baseline pass plus named-mutant failure;
the ordinary production-bug requirement that a new test fail on clean `main`
does not apply. Gate 4 is one bounded final review after the candidate is frozen
unless a risk trigger or repository policy requires more.

### Refactor path — conditional phases

| Conditional phase | Skip criterion |
|---|---|
| 4 — Specification and decomposition | The refactor is fully characterized by the architecture delta and characterization-test plan; no separate `SPEC.md` is needed because no behavior changes. |
| 5 — Test and verification planning | Existing characterization tests cover the affected surface; the test strategy is recorded as "existing suite, no additions." |

Gates 1, 4, and 5 are always mandatory on this path. Gates 3 and 2 are
conditional (skipped only with their phases, with recorded reasons).
Behavior-preservation evidence (characterization tests passing before and after)
is the gate 5 criterion. See [stages.md](stages.md) for the full matrix.

---

## Conditional specialist routing

Each phase that involves specialist work resolves its routing via the
[routing table](routing-table.md). The journey does **not** unconditionally load
every specialist at every phase. Instead:

1. Evaluate each routing row's applicability signal against the change surface.
2. Select the applicable specialists; record the per-stage lead when several
   compose (packet group (e)).
3. For every skipped specialist, record the skip with a reason citing the row's
   skip rule — e.g., "frontend-engineering skipped: no client-side application
   code modified."
4. The `opensource-contributions` skill is loaded **only** for public/OSS
   repositories; for private or enterprise repositories it is skipped with the
   reason "non-public repository."
5. When **no** applicability signal triggers, work proceeds on the neckbeard
   spine and the packet records "no specialist selected — no applicability signal
   triggered."

---

## Materiality and the re-review trigger

A **material** post-review change — one introduced in response to review feedback
after phase 7 has passed — invalidates prior verification and review verdicts and
requires re-entry through phase 7 (independent review and boundary verification)
before the readiness gate (phase 8) can be satisfied.

The canonical material/non-material definition is owned by
[stages.md](stages.md) (§ Gate 5 — Material change definition) and is the single
source of truth referenced by this journey, by
[delivery-packet.md](delivery-packet.md), and by [lifecycle.md](lifecycle.md):

- **Material** (invalidates prior verdicts, requires re-verification): a change
  that alters logic, adds or removes functionality, modifies the verification
  surface, changes test assertions, or alters data flow across a trust boundary.
- **Non-material** (prior verdicts stand; SHA binding updated): typo fixes,
  formatting-only changes, comment-only edits, pure renames without behavior
  change, docs-only changes, and rebases that produce no semantic diff.

After a material change, affected gates re-run and new verdicts are bound to the
new head SHA. After a non-material change, the recorded head SHA is updated and
the update is logged (old SHA → new SHA, materiality: non-material); prior
verdicts are not re-run. The final verified head SHA in packet group (i) must
always equal the actual final head of the delivered change.

---

## Authority boundary: readiness versus release

Phase 8 and phase 9 enforce a **hard authority boundary**:

- **Phase 8** ends with a readiness gate that declares the change ready for
  review submission or merge consideration. It does **not** authorize merge or
  release. "Ready for review" is not "ready to release."
- **Phase 9** begins only after merge (or equivalent acceptance) and requires
  **separate, explicit authorization** for release activity (tagging, publishing,
  deploying). Merge authority does not imply release authority
  (see [risk-authority-gates.md](risk-authority-gates.md)).

A change that passes phase 8 does not automatically enter phase 9. The two
authorities are never conflated.

---

## Phase continuity

The output of each phase is a required input to the next. Outputs flow through
named delivery-packet field groups:

| Phase | Produces (packet group) | Consumed by |
|---|---|---|
| 1 — Intake | (a) provenance, (b) authority/mode/path | Phase 2 (input: change contract) |
| 2 — Discovery | (d) baseline evidence, affected surfaces | Phase 3 (input: current-state evidence) |
| 3 — Design delta | (f) architecture delta, decisions, risks | Phase 4 (input: approved design, gate 1) |
| 4 — Specification | (g) `SPEC.md`, `TASK-PLAN.md` | Phase 5 (input: approved spec, gate 3) |
| 5 — Verification planning | (g) `VERIFICATION-PLAN.md` | Phase 6 (input: approved plan, gate 2) |
| 6 — Implementation | Commits, (c) head SHA updated | Phase 7 (input: complete implementation) |
| 7 — Review + verification | (h) gate 4 + gate 5 verdicts, `VERIFICATION.md` | Phase 8 (input: verdicts at known SHA) |
| 8 — Readiness | (i) PR/CI/review/final verified head SHA | Phase 9 (input: merged change, readiness evidence) |
| 9 — Release + closeout | (i) terminal state + evidence + rollback/follow-up triggers + lesson capture (or "no reusable lesson identified") | Record complete (terminal; triggers and lessons are recorded in the terminal record, not consumed — re-entry starts a new packet via phase 1 intake, carrying the lesson reference) |

Every field group written by a phase is consumed by a named later phase or
recorded as terminal evidence. No output is orphaned.

## Gate summary

Five gates block phase progression. Gate numbering groups gates by area and does
not imply chronological order. The execution sequence is:

> gate 1 (phase 3→4) → gate 3 (phase 4 exit) → gate 2 (phase 5→6) → gate 4
> (phase 7) → gate 5 (phase 7→8)

Full definitions, verdict semantics (pass/conditional/blocked), and per-gate
evidence requirements are in [stages.md](stages.md) (§ Change-request gates).
Every gate verdict is recorded in packet group (h) with the gate identifier,
verdict, evidence references, and the exact head SHA.

---

## Escalation and stop rules

Phase escalation conditions are consistent with the stop rules in
[risk-authority-gates.md](risk-authority-gates.md). The hard stops apply at every
phase boundary:

- Never delete data, branches, releases, or infrastructure without an explicit
  human directive.
- Never escalate privileges (credentials, tokens, IAM, secrets).
- Never force-push, rewrite history, or overwrite a protected ref.
- Never deploy or merge when authority was not granted for that class.
- Stop when two materially different approaches have failed.
- Stop when the only available verification is weaker than the declared target
  and the gap is material.
- Stop when an instruction conflicts with a hard constraint.

A gate verdict of **blocked** stops the run and transitions the packet to the
**blocked** lifecycle state; the run does not continue without new authority
(see [delivery-packet.md](delivery-packet.md), blocked-state semantics).
Persistence does not upgrade authority.

# Change Lifecycle Integration

The platform mechanics for carrying a change request from intake to an authorized
post-merge release. This reference is loaded by [../SKILL.md](../SKILL.md)
**only** for change-request / issue-to-PR / ticket-to-release work — a request
that will produce a pull request or an equivalent reviewable deliverable. A
single-line edit, an ad-hoc fix, or a review without an issue/ticket trajectory
does **not** load this reference; that work uses the core loop in
[../SKILL.md](../SKILL.md).

The lifecycle does not invent phases or gates. It maps onto the nine-phase
change-request journey ([journey.md](journey.md)) and the five gates
([stages.md](stages.md)). It records its outcomes in the delivery packet
([delivery-packet.md](delivery-packet.md)), field group (i) — PR/review-submission
number, CI status, review status, **final verified head SHA**, release status,
and terminal-state evidence plus rollback/follow-up triggers and closeout lesson
capture. Stop and escalation
rules live in [risk-authority-gates.md](risk-authority-gates.md).

## Two modes, one structure

The workflow is platform-neutral. Two documented modes share the **same phase
sequence, the same five gates, and the same packet fields**; only the platform
mechanics differ.

| | **GitHub reference mode** | **Enterprise mode** |
|---|---|---|
| Use when | The target repository is **public/open-source** (public remote, open-source license, contribution governance). | The target repository is **private or enterprise-internal**: ticket trackers, private hosting, enterprise review and CI tooling, change governance. |
| Source of truth | An issue in the repository tracker. | A ticket, email thread, or verbal request. |
| Review submission | A pull request. | An enterprise change request / review submission. |
| Authority to merge | Maintainer action on a protected branch. | Enterprise approval workflow / change manager. |
| Authority to release | A separate grant beyond merge. | A separate authorization (CAB, change-manager sign-off, change-freeze window). |

**Mode selection is recorded** in packet group (b). GitHub is a documented
*reference* mode, never the assumed default. Enterprise mode makes no
open-source assumption — no public visibility, no fork-based contribution, no
community norms.

---

## GitHub reference mode

GitHub mechanics are described here; contribution *norms* are delegated to the
catalog skill `opensource-contributions` and are discovered **per repository**,
never hardcoded.

### Contribution-norm delegation (public/OSS only)

> **Load `opensource-contributions` only when the repository is public/OSS**
> (public remote and an open-source license). It owns contribution-norm detail:
> `CONTRIBUTING.md` interpretation, agent disclosure, fork etiquette, commit
> conventions, PR templates, and post-submission etiquette. This reference
> **delegates** to it and does not re-derive its content.

If the repository is private or enterprise-internal, do **not** load
`opensource-contributions`; use enterprise mode below, and record the skip in
packet group (e) with the reason "non-public repository."

### 1. Snapshot the issue and repository context before planning — phase 1

Before any planning or implementation begins, capture **all** of the following
as mandatory intake artifacts. The phase 1 intake gate
([journey.md](journey.md)) cannot be satisfied without them.

- **Issue body** — the full request text.
- **All issue comments** — not just the opening post.
- **Linked and referenced work** — related issues, PRs, and commits that touch
  the same problem.
- **Repository conventions** — `CONTRIBUTING.md`, `AGENTS.md`, `.github/`
  templates, or equivalent, **discovered per repository**.
- **Base ref** — the current base branch ref the change will target.

Record these in packet group (a). Planning may not start until the snapshot is
complete.

### 2. Classify authority — phase 1

Classify the granted authority into **four separate classes** and record each
before implementation. These complement the authority classes in
[risk-authority-gates.md](risk-authority-gates.md) (Explore / Modify / Publish /
Deploy / Merge); they are never collapsed into a single "has access" judgment.

| Class | Scope |
|---|---|
| **Contributor** | Can fork, branch, and open a PR. |
| **Maintainer** | Can approve, review, and close. |
| **Merge** | Can land a change into a protected branch. |
| **Release** | Can tag, publish, or deploy. |

Record the granted class per row in packet group (b). A contributor grant does
not imply merge or release authority. Merge authority does not imply release
authority (see [Authority boundary](#authority-boundary-readiness-vs-release)).

### 3. Pre-work integrity checks — phases 1–2

These checks run **before** a branch is created and before work proceeds. Each
has its own recorded outcome in the packet; they are distinct, not one merged
check.

| Check | What it does | Recorded outcome |
|---|---|---|
| **Duplicate-issue search** | Search the repository issue tracker for an existing issue describing the same or overlapping problem. | "duplicate found and handled" or "no duplicate." |
| **Existing-PR search** | Search for **open and recently closed** PRs addressing the same issue or problem, including PRs from other contributors not linked to the issue. | "PR found — see handling" or "no existing PR." |
| **Conflicting-branch check** | Check whether another contributor has already pushed a branch targeting the same issue or change surface. | Coordinate, wait, or proceed-with-awareness decision. |
| **Maintainer-direction review** | Review issue comments, assignments, labels, and governance docs for explicit direction ("I'll handle this," "don't work on this yet," "assigned to X," a deferral label). | Proceed, or **stop/escalate** if direction conflicts. |

**Maintainer direction is a hard gate.** If maintainer direction conflicts with
proceeding, the agent must **not** proceed regardless of the other checks. This
is consistent with the stop rules in
[risk-authority-gates.md](risk-authority-gates.md).

**Handling an existing open PR (no duplicate work).** When the existing-PR
search finds an open PR addressing the same problem, decide and record:

- **Continue/assist** if it is the agent's own prior work — resume from packet
  state ([delivery-packet.md](delivery-packet.md), resumability).
- **Coordinate or defer** if another contributor owns it.
- **Never open a duplicate PR.** The decision is recorded in the packet.

### 4. Determine fork-vs-branch before PR creation — phase 6

Before creating a branch or PR, determine the repository's contribution workflow
from `CONTRIBUTING.md`, `.github/` conventions, or maintainer direction —
**per repository**, never assumed:

- **Fork-and-PR** vs **branch-in-repo**.
- Record the choice in the packet, and apply fork etiquette via
  `opensource-contributions` when a fork is required.

The lifecycle never assumes a branch-in-repo workflow or leaves the mode
implicit.

### 5. PR readiness, submission, and merge are separate states — phases 6–8

These three states are explicitly distinct; reaching one does not grant the next.

| State | Meaning | Who controls it |
|---|---|---|
| **Ready** | Code complete, self-reviewed, tests pass locally, verification evidence recorded. | The agent can reach this independently. |
| **Submitted** | The pull request is opened. | The agent performs the act of opening. |
| **Merged** | The change lands in the protected target. | Requires **maintainer action** plus passing CI and approved review — **not** the agent's own readiness assessment. |

Merge is gated on external authority beyond the agent's readiness declaration.

**Issue linkage and closing keywords.** The PR body must (a) reference the
source issue by number and (b) use the repository's own closing-keyword
convention, discovered from `CONTRIBUTING.md` or project norms (e.g.,
`Closes #N`, `Fixes #N`, `Resolves #N`). If the repository specifies no
convention, use a defensible default: `Closes #N`.

**PR body content.** Beyond the issue link and closing keyword, the PR body
describes the change — **what** it does, **why**, and **how it was verified** —
and follows the repository's PR template if one exists (discovered per
repository).

### 6. Post-submission monitoring — phase 8

After the PR is submitted, both monitors are mandatory and run until they
terminate; checking once is not enough.

**CI monitoring.** Monitor CI status until CI completes. CI failure is a
**blocking** condition: the PR is never merge-ready while CI is red. When CI is
red, **triage** it:

1. **Diagnose** the failure from the logs.
2. **Fix** it if the failure is attributable to the change.
3. **Escalate** when the failure is undiagnosable after two attempts
   (per [risk-authority-gates.md](risk-authority-gates.md)).

Never consider the PR merge-ready, and never merge it, while CI is failing.

**Review monitoring.** Monitor for review feedback (comments, change requests,
approvals) and respond to **material** feedback with code changes rather than
argument. Review monitoring is distinct from CI monitoring.

### 7. Material change and exact-head binding — phases 7–8

Every material change pushed after initial submission — any change that alters
behavior, fixes a bug, or responds to review feedback beyond a trivial typo fix
— **invalidates prior verification verdicts** and must return through both
independent review (**gate 4**) and boundary verification (**gate 5**) before
the PR is merge-ready again. A stale verdict on a superseded head SHA is never
carried forward; the new head is independently verified.

Materiality uses the **canonical definition** owned by [stages.md](stages.md)
(§ Gate 5 — Material change definition):

- **Material** (invalidates verdicts, re-verify): alters logic, adds/removes
  functionality, modifies the verification surface, changes test assertions, or
  alters data flow across a trust boundary.
- **Non-material** (verdicts stand, SHA binding updated): typo fixes,
  formatting-only, comment-only edits, pure renames without behavior change,
  docs-only changes, and rebases with no semantic diff.

**The merge-readiness verdict is bound to the exact full head SHA.** No verdict
is valid without a bound SHA, and a verdict referencing a different SHA (e.g.,
from before a rebase or force-push) is explicitly **stale and insufficient**.

**Update the final-verified-head-SHA field after every review round.** Each
review round ends with packet group (i) **final verified head SHA** refreshed to
the current head and fresh verification evidence recorded for that head:

- A round that pushes a change updates the field and re-runs verification.
- A round that changes nothing keeps the existing SHA.

The final verdict is always bound to the exact final head of the delivered
change. This is the same rule expressed in [journey.md](journey.md) phase 8 and
in the packet's exact-head-binding section.

---

## Enterprise mode

Enterprise mode uses the **same nine phases and five gates** as GitHub mode. It
makes no open-source assumption and does not reference `opensource-contributions`.

### 1. Source-of-truth snapshot — phase 1

Capture the authoritative request from wherever it actually lives — it is **not**
assumed to be a GitHub issue:

- A **ticket-tracker** entry (ticket ID, description, comments), **or**
- an **email thread**, **or**
- a **verbal** request (transcribed with attribution).

Record the snapshot, the repository, and the base ref in packet group (a). The
phase 1 intake gate cannot be satisfied without it.

### 2. Duplicate / existing-change-request check — phases 1–2

Equivalent to the GitHub duplicate-issue and existing-PR checks:

- Search the ticket tracker for an **open change request** covering the same
  problem.
- Search for any **existing change branch / CR in flight**.
- **Record the result.** If one exists, coordinate or defer.

Enterprise intake does not end at snapshotting the ticket; the dedup outcome is
recorded in the packet.

### 3. Authority classification and approval gate — phases 1, 7

Classify authority using the same four classes as GitHub mode (contributor,
maintainer-equivalent, merge, release) and record them in packet group (b).

**Explicit approval gate.** Enterprise review requires a named approver sign-off
that the **merge gate depends on**:

- a **named reviewer/approver**;
- a **recorded verdict** in the packet;
- the verdict **feeds the merge gate** (phase 8 readiness → merge).

This is the enterprise equivalent of GitHub review approval (gate 4). Review is
not merely "integrating with review tooling" — it produces a recorded approval
verdict.

### 4. Enterprise CI and change governance — phase 8

- **Enterprise CI.** Integrate with the enterprise CI system (not assumed to be
  any particular provider); monitor it after submission exactly as GitHub mode
  monitors CI, and triage red CI (diagnose, fix, or escalate). The PR/change is
  never merge-ready while CI is red.
- **Change-governance boundaries.** Respect **CAB approval**, segregation-of-
  duties constraints, and **change-freeze windows**. A change-freeze that blocks
  deployment is an escalation condition ([journey.md](journey.md) phase 9).

### 5. Release authority separation — phase 9

Release activity (deploy, publish, promote) requires **explicit authorization
distinct from merge approval** — for example CAB approval, change-manager
sign-off, or change-freeze-window clearance. The merge/approval gate alone does
**not** authorize release. Record the authorization in the packet's
**release status** field. This mirrors the GitHub-mode authority boundary and
the release gate in [risk-authority-gates.md](risk-authority-gates.md).

### Packet portability across modes

The packet is mode-agnostic: the same nine field groups, with the same field
names and semantics, are populated in both modes. GitHub-only fields have
documented enterprise equivalents:

| Packet field (group i) | GitHub mode | Enterprise equivalent |
|---|---|---|
| PR (review-submission) number | Pull-request number | Enterprise change-request / review ID |
| CI status | Hosted CI result | Enterprise CI result |
| Review status | PR review approval | Named-approver sign-off verdict |
| Final verified head SHA | Head commit SHA | Head commit SHA (identical) |
| Release status | Tag/publish disposition | Deploy/promote disposition (CAB/clearance) |

No packet field is fillable only in GitHub mode.

---

## Authority boundary: readiness vs release

Pre-merge **release readiness** and post-merge **release activity** are separate
gates with separate authority, in both modes.

- **Release readiness (pre-merge, assessable):** the change is releasable —
  version bumped, changelog updated, migration documented, rollback plan exists.
  This can be confirmed before merge and feeds the readiness gate (phase 8).
- **Release activity (post-merge, gated):** tagging, publishing artifacts,
  deploying, announcing. This is a **separate gate requiring explicit
  authorization beyond merge authority.** Merge does not imply release.

The merge gate verifies readiness; release execution is gated on a separate
explicit authorization. See [risk-authority-gates.md](risk-authority-gates.md)
for the merge gate and release gate definitions.

### Release execution records post-release verification

The release gate does **not** end at the authorization grant. Before the
`released` terminal state is declared, record **post-release verification
evidence** — a post-release smoke check, deploy/tag confirmation, or artifact
checksum — in the packet's **release status** field.

---

## Terminal states

Exactly four terminal states end a lifecycle, each requiring specific evidence
recorded in packet group (i). There is no ambiguous "done" without evidence.

| Terminal state | Meaning | Required evidence |
|---|---|---|
| **merged** | Landed into the protected target. | The **merge commit SHA**. |
| **closed** | Not merged; ended without code. | The **close reason** (e.g., duplicate, already fixed, withdrawn). |
| **blocked** | Cannot proceed. | **Blocker evidence** — the blocking condition and any escalation outcome. |
| **released** | Authorized post-merge release completed. | **Release evidence** (tag, artifact, deploy confirmation, post-release smoke check). Terminal — no transitions out. |

These are the same terminal states defined by the packet
([delivery-packet.md](delivery-packet.md), lifecycle states) and by journey
phase 9 closeout ([journey.md](journey.md)). A terminal packet is never
re-opened; new work starts a new packet. Closeout also records
**rollback/follow-up triggers** — what would cause re-entry — and **lesson
capture** per Stage 6 "Deliver and learn" ([stages.md](stages.md)): the reusable
lesson(s) with their durable destination, or an explicit "no reusable lesson
identified" determination — in group (i); a fired trigger starts a new change
request via phase 1 intake, it does not resurrect the terminal packet.

### Reduced paths still terminate with evidence

A reduced (lightweight) run terminates in a defined terminal state, not an
unspecified early stop:

- A **no-change-needed** run records the determination and transitions to
  **closed** with the close reason and its evidence (no PR created).
- A **docs-only** change that ships reaches **merged** with the merge SHA (doc-
  update evidence).

The packet's terminal lifecycle state field is populated on every reduced path.

### External cancellation mid-flight

If the change request is closed or cancelled by an external actor at any phase
after intake — a maintainer closes the issue, a ticket is withdrawn, a PR is
closed by a maintainer — the packet transitions to the appropriate terminal
state (**closed** or **blocked**) with the **external closure as evidence**, and
the remaining phases are **not** executed. This is distinct from the
no-change-needed termination ([journey.md](journey.md)) and from the
gate-failure **blocked** state ([delivery-packet.md](delivery-packet.md)).

---

## Delivery-packet fields this reference reads and writes

The lifecycle records its outcomes in the packet. It reads provenance and
authority from groups (a)–(b) and writes to the groups below; every named field
exists in [delivery-packet.md](delivery-packet.md).

| Lifecycle step | Packet field(s) | Group |
|---|---|---|
| Snapshot the issue / source of truth | Issue snapshot (request text, comments, linked work) | (a) |
| Classify authority | Authority class (contributor / maintainer / merge / release) | (b) |
| Record mode and pre-work check outcomes | Workflow mode; dedup/PR/branch/maintainer-direction decisions | (b), (e) |
| Open the PR / review submission | PR (review-submission) number | (i) |
| Monitor CI | CI status | (i) |
| Monitor review | Review status | (i) |
| Bind verdicts per review round | **Final verified head SHA** | (i) |
| Assess release readiness and execute release | Release status (with post-release verification evidence) | (i) |
| Close out | Terminal lifecycle state + terminal-state evidence (merge SHA / close reason / blocker evidence / release evidence) + rollback/follow-up triggers + lesson capture (or "no reusable lesson identified") | (i) |

Field group (i) — PR number, CI status, review status, final verified head SHA,
release status, terminal-state evidence, rollback/follow-up triggers, and
lesson capture — is
the exact set this reference populates; the match is bidirectional (no field
here that the packet lacks, and no group-(i) field the lifecycle never writes).

## Lifecycle-to-journey mapping

Every lifecycle step and every packet lifecycle state maps onto a journey phase
that [journey.md](journey.md) defines. No phase here is invented or renamed.

| Lifecycle step | Journey phase |
|---|---|
| Snapshot, authority classification, pre-work checks, fork-vs-branch decision | Phase 1 (intake and provenance) and phase 6 (implementation) for branch creation |
| Duplicate / dedup and discovery | Phase 2 (current-state discovery and reproduction) |
| Implementation commits | Phase 6 (domain-specific implementation) |
| Independent review, boundary verification, CI/review monitoring, exact-head re-verification, readiness | Phase 7 (independent review and boundary verification) and phase 8 (readiness, CI/review loops) |
| Merge / approval gate | Phase 8 → phase 9 boundary |
| Authorized release, closeout, terminal-state evidence | Phase 9 (authorized post-merge release and closeout) |

| Packet lifecycle state | Journey phase |
|---|---|
| intake | Phase 1 |
| planning | Phases 2–5 |
| implementation | Phase 6 |
| in-review | Phases 7–8 |
| ready | End of phase 8 (readiness gate passed) |
| merged / closed / blocked / released | Phase 9 (terminal closeout) |

# Lightweight Test-Hardening Path

Test-hardening is a subtype of the lightweight delivery path. Use it when the
production behavior is already correct and the change adds a regression guard
for a known coverage gap, mutation survivor, or controlled weakening.

It is not an ordinary production bugfix. Do not require the new test to fail on
clean `main` when the purpose of the test is to distinguish the clean behavior
from a named mutant.

## Applicability

Use this subtype only when all of these are true:

- production/runtime code remains unchanged;
- the change is confined to one or a few test or fixture files;
- no dependency, configuration, authentication, cryptography, deployment, or
  public API surface changes;
- the current behavior and the intended invariant are understood; and
- the regression can be exposed by a focused deterministic test plus a bounded
  controlled weakening or targeted mutant.

If any condition fails, select the ordinary lightweight, full, refactor, or
high-risk path instead.

## Required evidence

Record a compact contract containing:

1. the public behavior or invariant being protected;
2. evidence that the clean implementation already satisfies it;
3. the named mutation or controlled weakening that must be rejected; and
4. explicit non-goals, including production-code changes when none are needed.

The test should exercise the public contract, use hermetic setup at the relevant
failure boundary, and assert the semantic invariant rather than an incidental
current implementation subtype or message.

The minimum verification set is:

- clean baseline passes;
- the named mutant or controlled weakening fails the new test;
- the focused suite passes on the clean candidate;
- lint, compilation, and changed-scope checks pass; and
- changed-file security and public-metadata checks pass.

When the repository already has a mutation-testing setup, record the mutant
evidence in `qa-methodology`'s bounded mutation-review format
([templates/mutation-review.md](../../qa-methodology/templates/mutation-review.md))
and follow its mutation-guided hardening methodology
([references/test-automation.md](../../qa-methodology/references/test-automation.md)).
The evidence contract above still governs; the mutation-review record is the
format, not a relaxation of the thresholds.

A full mutation campaign, full-repository scan, or broad integration run is not
required by this subtype unless the changed surface or repository policy makes
it relevant. Record any boundary that was not exercised.

## Finality before remote CI

For repositories with expensive or serialized CI, finish the test design,
hermeticity review, targeted mutation, focused suite, lint, compilation, and
scope checks before the first push. The goal is one stable candidate and one
remote verification cycle.

After the candidate is frozen, use one bounded independent review or the
repository's required platform review. Do not start multiple long-running
reviewers by default. A timeout is inconclusive; it does not justify launching
another review against a mutable or superseded candidate.

A material review-driven change invalidates the relevant verification and
requires re-verification at the new exact head SHA. Formatting-only or
comment-only changes may follow the repository's non-material update rule.

# Position Assessment — Mid-Flight Engagement Entry Mode

Some engagements begin mid-flight: the agent is asked to continue software
delivery work that started elsewhere — a half-implemented branch, an adopted
specification, a change request another contributor began — and no delivery
packet exists because the earlier work did not run inside this bundle. The
nine-phase journey ([journey.md](journey.md)) describes the canonical forward
path from intake; it does not describe how to enter that path honestly when the
first six phases may already be partly done.

This reference defines that entry mode. It is loaded by [../SKILL.md](../SKILL.md)
only for mid-flight engagement. It is **not** loaded when a fresh change request
starts the journey at phase 1, and **not** loaded when the run's own delivery
packet exists — packet resumability
([delivery-packet.md](delivery-packet.md)) governs that case, and the packet is
authoritative there.

The procedure answers three questions before any execution continues:

1. What step is the work actually on?
2. Which gates have evidence behind them, and which remain?
3. What is the next justified action?

## The core rule: artifacts, not narratives

Position is established from observable artifacts — files, commits, CI runs,
review states — scored against the exit conditions the phases define. It is
never established from summaries, however confident. "The spec was approved"
is not a satisfied gate; an approved `SPEC.md` artifact with a recorded gate
verdict is. A claim with no inspectable artifact behind it becomes a recorded
**unverified assumption**, never a satisfied gate.

This is the same doctrine the rest of the bundle applies to verification:
assertions are not evidence. Assessment inherits it.

## Procedure

### Step 1 — Trigger check

Enter this mode only when all three hold:

| Condition | How to check |
|---|---|
| The request is to continue existing delivery work | The request references ongoing work (a branch, spec, partial implementation) rather than a fresh change |
| No delivery packet exists for that work | No packet artifact accompanies the work; the prior run, if any, was outside this bundle |
| The work is non-trivial enough to warrant the journey | Same threshold [../SKILL.md](../SKILL.md) applies before loading the journey |

If a delivery packet exists, use [delivery-packet.md](delivery-packet.md)
resumability instead. The empty-inventory case ("no artifacts found") can only
be determined after running step 2's inventory; when it holds, assessment
still completes normally — deliver a position report stating phase 1 and
perform the step-5 bootstrap, then let the normal journey take over. An empty
inventory is a finding, not a failure, and it does not skip the report or the
packet.

### Step 2 — Inventory the observable artifacts

Search the working repository and tracker for the artifacts the phases would
have produced. When artifacts live in a tracker, identify which tracking system
that is during this pass, per
[tracker-discovery.md](tracker-discovery.md), so the intake field exists by
bootstrap time.

| Observable artifact | Produced by | Typical locations |
|---|---|---|
| Change contract (problem, constraints, authority) | Phase 1 | Issue/ticket body, PR description, [../templates/change-contract.md](../templates/change-contract.md) instance |
| Repository conventions captured | Phase 1 | Evidence that `CONTRIBUTING.md` / `AGENTS.md` were consulted |
| Baseline and reproduction evidence | Phase 2 | Repro steps in the issue, failing-test transcripts, benchmark notes |
| Architecture delta, ADR, C4 diagrams, or a documented no-delta determination | Phase 3 | `docs/adr/`, design docs, decision-record instances |
| `SPEC.md`, `TASK-PLAN.md` | Phase 4 | Repository root or working branch |
| `VERIFICATION-PLAN.md` | Phase 5 | Working branch |
| Implementation commits on a working branch | Phase 6 | `git log <base>..HEAD` |
| `VERIFICATION.md`, independent review verdicts | Phase 7 | Working branch, PR review states |
| Green CI and approved review at a known head SHA | Phase 8 | CI checks, review approvals bound to a specific SHA |
| Merge commit, release tag, deploy confirmation | Phase 9 | Protected-target history, tags, deploy logs |

Inventory reads are read-only discovery; they need no confirmation. Record
where each artifact was found (path, SHA, URL) — pointers become the evidence
references in the report.

**Re-select the delivery path here, before scoring.** Run the path-selection
rule ([../SKILL.md](../SKILL.md) § Path selection) against the affected surface
and risk observed in the inventory; do not inherit a path assumption from the
prior work. The selected path determines which phases are mandatory to score.

### Step 3 — Score against phase exit conditions

Compare each inventoried artifact with the exit condition and gate definition
of its phase ([journey.md](journey.md); gate semantics in
[stages.md](stages.md)). Assign exactly one verdict per phase:

| Verdict | Meaning |
|---|---|
| **Satisfied** | The artifact exists and meets the phase exit condition. Record the evidence pointer. |
| **Partial** | The artifact exists but is incomplete or unapproved. Name exactly what remains. |
| **Absent** | No artifact found. The gate is not passed. |
| **Contradicted** | An artifact exists but observable evidence conflicts with it (for example, readiness claimed while CI is red at the recorded head). Contradiction blocks progression until resolved. |

Scoring constraints:

- **Authenticate before crediting.** Artifacts authored by the same party that
  produced the working branch — committed specs, verification and review
  files, "no delta" determinations, claimed approvals or CI outcomes written
  into the branch — are **attacker-forgeable** in exactly the adopted-branch
  scenarios this mode exists for. Approval- and authority-carrying evidence
  is scored `satisfied` only when corroborated from an independent source:
  an approval or review recorded on the remote platform by a real identity
  distinct from the branch author, or CI results queried from the remote and
  bound to the exact head SHA. This covers the approved architecture delta at
  gate 1, the QA-owned verification plan at gate 2, the approved specification
  at gate 3, review verdicts and boundary verification at gates 4–5, and
  readiness. Re-derivation is available only for **technical or factual
  judgments** the agent can legitimately re-run itself — for example,
  re-checking a "no architecture delta" note against the actual diff, or
  verifying spec acceptance criteria against the change contract. It is never
  available for an approval verdict itself: agent judgment does not
  substitute for the human-or-distinct-reviewer approval the gate requires,
  and a gate whose approval cannot be independently corroborated stays at
  best `partial`. Evidence that can be neither corroborated nor (where
  legitimate) re-derived is scored `absent` with the uncorroborated claim
  recorded in the ledger. The same weighting doctrine tracker-discovery
  applies to repository signals applies here.
- Score the delivery path selected in step 2; conditional phases are scored
  only if their artifacts exist (an absent conditional phase with a legitimate
  skip reason is recorded as such, not penalized).
- Verified-complete work is **not** re-executed, mirroring packet-resume
  semantics. Assessment establishes position; it does not redo accepted work.
- Never upgrade a verdict to fill a gap. A missing gate verdict is `absent`,
  even when the underlying work looks done.
- Two contradictory sources (artifact says approved, tracker says changes
  requested) yield `contradicted`, and the conflict itself is reported.

### Step 4 — Emit the position report

Produce the report and deliver it to the requester **before** continuing
execution. Format:

```
current phase:        <n>-<phase-name>
selected path:        <lightweight|full|refactor|high-risk>
assessment head SHA:  <git rev-parse HEAD at assessment time>
satisfied gates:      <gate> @ <evidence pointer>; ...
partial:              <gate/artifact> — <what remains>
absent:               <gates with no evidence>
contradicted:         <gate/artifact> — <conflicting evidence>
remaining checklist:  [ ] <next gate/action>; [ ] ...
unverified assumptions: <claims accepted provisionally, with owner of the proof>
recommended next action: <single bounded step>
```

The remaining checklist is the contract for continuation: work proceeds
against it in journey order, respecting the five-gate sequence and every stop
rule in [risk-authority-gates.md](risk-authority-gates.md).

### Step 5 — Bootstrap the packet

Create a fresh delivery packet so subsequent operation has normal resumability.
Group (c) initialization derives its fields from the report: the current phase
comes from the report's `current phase` field, and the **current gate** is the
first gate in the remaining checklist (or "none — awaiting next phase entry"
if the checklist starts at a phase rather than a gate).

- Group (a) provenance records: engaged mid-flight, artifacts assessed, with
  the inventory pointers, and the tracking system identified during the
  inventory pass per [tracker-discovery.md](tracker-discovery.md), with its
  evidence basis — satisfying the intake-gate field this bootstrap must carry.
- Group (b) records the delivery path selected in step 2 (path selection per
  [../SKILL.md](../SKILL.md) § Path selection was re-run during assessment; no
  path assumption was inherited from the prior work) **and establishes the
  granted authority class**. Authority is a human grant, not an artifact
  finding: an authority claim found in branch-authored material (a change
  contract or handoff note saying "merge approved") is treated as an
  unverified assumption, never as granted authority. The bootstrap records
  `explore (assumed)` — the packet template's own flagged fallback — unless
  the requester independently grants a higher class for this run; any
  higher-class work (merge, deploy, publish) then requires that explicit
  grant before it may proceed, per
  [risk-authority-gates.md](risk-authority-gates.md).
- Group (e) records the routing decisions established during assessment: the
  tracker tooling skill selected per [tracker-discovery.md](tracker-discovery.md)
  step 5, and every skipped specialist with its skip reason where the
  inventory supports one. Silent omission is prohibited, same as intake.
- Group (c) records: current phase and current gate as derived above; the
  **last passed gate verdict head SHA** taken from the highest satisfied gate's
  own evidence SHA (recorded as `none` when no gate is satisfied — never the
  assessment-time HEAD, which would imply a passed verdict that group (h)
  does not contain); and the **current lifecycle state**, mapped from the
  assessed position using the packet's enumerated vocabulary (`intake` for an
  empty inventory or a position at phase 1; `planning` for positions in phases
  2–5; `implementation` for phase 6; `in-review` for phase 7; `ready` for a
  position at phase 8; `merged` when the inventory shows a merge commit into
  the protected target but release is pending; `released` when release
  evidence exists; `blocked` if assessment found a contradicted gate that
  stops progression).
- Unverified assumptions go to the evidence ledger
  ([evidence-ledger.md](evidence-ledger.md)), not into gate fields.

Do **not** retroactively mark gates as passed in group (h) without artifacts.
Gates with genuine evidence pointers may be recorded as passed with those
pointers; everything else remains open.

## Completion and exit conditions

Assessment is complete when the position report has been delivered and the
packet bootstrapped. The mode then ends: execution continues under the normal
journey and core loop. If the inventory is empty, completion is the honest
statement "no artifacts found — starting at phase 1" plus the same bootstrap.

## Non-goals

- This is not a quality audit of the existing work. It establishes position;
  phase 7 review still judges quality.
- It does not bypass gates. Only gates with real evidence may be marked
  satisfied; the rest must actually run.
- It does not replace packet resumability. Where a packet exists, the packet
  wins.
- It does not guess at intent behind ambiguous prior work. When the change
  contract cannot be reconstructed from artifacts, that is a phase-1 gap, and
  intake happens properly.

# Progress and Finality

How to judge whether work is advancing, when to keep going, when a bounded
check of an asynchronous dependency is justified, and when to stop or
escalate. One rule governs every section: **decide on semantic state — never
on elapsed time, iteration counts, timestamps, request IDs, or how many times
the same state has been observed.**

## Semantic progress, not iteration count

Progress means the world changed in a way that moves an acceptance criterion
forward: a changed artifact, a confirmed or falsified hypothesis, a new stage,
a changed dependency state, or a new output cursor from an asynchronous
system. An advancing timestamp, a fresh request ID, a poll counter, or the
continued existence of a process is *volatile churn* — it is not progress and
must never be recorded as evidence of progress.

Judge churn by content, not by source. A heartbeat whose only change is its
timestamp is churn. But a heartbeat that carries an advancing payload — a new
phase or step, a processed-item count, a new output cursor — is reporting
semantic state: record that payload in the declared semantic state, and it
counts as progress. The timestamp itself stays out of the fingerprint either
way.

The failure mode this page prevents is not "too many turns." It is repeated
observation of an unchanged semantic state while the declared stage action
remains untaken.

## The dependency contract

When a stage hands off to an asynchronous system, record — in the change
contract and the evidence ledger — whether a dependency is required for the
next stage:

- **Accepted/finished output with no required dependency:** the next action is
  to advance or deliver, or to declare the run terminal-complete. A status
  poll before that action is never justified.
- **A pending or failed dependency explicitly required for the next stage:**
  a bounded check is justified once (see below). Required-or-not is part of
  the contract, not something to re-derive mid-run.

Treat `accepted`/`finished` as a stage output, not automatically as whole-run
completion. Terminality is declared only when the contract has no required
dependency left.

## Bounded checks

One infrastructure check per normalized state fingerprint. The fingerprint is
computed from: stage, deliverable state, dependency state, whether the
dependency is required, and the declared semantic state. Volatile fields —
timestamps, request IDs, raw poll counters — are excluded from the
fingerprint, so a timestamp-only heartbeat difference is unchanged state. An
advancing heartbeat payload (a new phase, step count, or output cursor)
belongs in the declared semantic state; when it advances, the fingerprint
changes and the new state receives its own check allowance.

- First observation of a fingerprint: one check is allowed.
- The fingerprint changes (pending → succeeded, or a new output cursor):
  continue; the new fingerprint gets its own check allowance.
- The fingerprint is unchanged: do not re-check. Change the mechanism or
  escalate. An identical re-poll is a finality failure even when the
  timestamp and request ID differ.

## Complex work

There is no arbitrary turn cap. Continue while each turn produces new
evidence or a changed semantic state and at least one acceptance criterion
remains unmet. Multi-turn diagnosis, design iteration, and long test loops
are productive work when the semantic state keeps changing; a turn-count
ceiling must never stop them.

## Active-process ledger

The evidence ledger stays canonical. When work is asynchronous — or an
escalation is being considered — extend the run's record with an
active-process entry:

| Field | Content |
|---|---|
| `id` | Stable identifier for the asynchronous hand-off. |
| `status` | Current normalized state. |
| `output` | Latest meaningful output or artifact reference. |
| `normalized_state` | Fingerprint inputs: stage, deliverable state, dependency state, dependency-required flag, semantic state. |
| `dependency_required` | Whether the dependency gates the next stage. |
| `next_action` | The declared stage action: `work`, `check`, `advance`, `deliver`, `complete`, `mechanism_change`, or `escalate`. |
| `expected_transition` | What the next *semantic* change would look like. |
| `checks_for_state` | How many checks this fingerprint has consumed. |
| `escalation_trigger` | The condition under which the next unchanged observation escalates. |

## Examples

**Accepted but not blocked.** The deliverable is accepted; a publish job is
pending, but nothing requires it before delivery. Correct: deliver or
complete now. Wrong: check the publish job first.

**Genuinely pending dependency.** The delivery stage requires a published
release. One check is spent; the next observation shows the dependency
succeeded with a new output cursor. Correct: proceed to delivery. If the
observation had been unchanged, the correct move is a mechanism change or
escalation — not a second check.

**Productive multi-step work.** Three turns on an in-progress deliverable,
each with a new hypothesis, benchmark, or artifact, ending in verification
and delivery. Correct at any length: every turn changed the semantic state.

**Identical re-poll (failure).** Two observations with identical semantic
state but different timestamps and request IDs, with a check on each, while
the delivery action stays untaken. This fails finality: the second check was
an identical re-poll; the response to the unchanged result should have been a
mechanism change or escalation.

## Non-portable examples excluded

Keep this contract harness-neutral. Do not express the rules in terms of
specific tool names, scheduler or cron identifiers, process IDs, platform API
names, or any vendor's polling semantics. Describe state, dependencies,
actions, and terminality; each harness maps them to its own mechanisms.

# Risk and Authority Gates

These rules decide when the agent may act and when it must stop and hand control
to a human. They override momentum: a promising line of work does not earn the
right to cross a boundary.

## Authority classes

Classify the granted authority at Framing and re-check it before each escalation
in scope.

| Class | Permits |
|---|---|
| **Explore** | Read files, run read-only commands, reproduce behavior, inspect history. No state change. |
| **Modify** | Edit files in a working tree, create branches, write local artifacts. No publish/deploy/merge. |
| **Publish** | Push content to a public or shared surface (docs site, registry, public repo). |
| **Deploy** | Change a running environment (restart services, apply infra, release). |
| **Merge** | Land a change into a protected branch. |

When the class is unclear, assume **Explore** and ask. Higher classes are never
implied by lower ones.

## The mutation gate

Before the **first** state-changing act in a run, confirm:

1. **Target** — exactly what will change.
2. **Scope** — the blast radius; what else could be affected.
3. **Rollback path** — how to undo it if it goes wrong.

Read-only discovery never needs this gate. The first mutation always does.

## Hard stops — never without an explicit human directive

- Deleting data, branches, releases, or infrastructure.
- Privilege changes (credentials, tokens, IAM, secrets).
- Irreversible cleanup or migration.
- Force-push, history rewrite, or overwriting a protected ref.
- Deploying or merging when authority was not granted for that class.

Persistence does not upgrade authority. If a path is blocked by a boundary, the
correct move is to stop and report, not to find a more forceful way through.

## Merge gate

Merge is the act of landing a change into a protected branch. It requires the
**Merge** authority class and cannot be satisfied unless **all three**
preconditions hold at the same commit:

1. **Exact final head SHA** — the precise, full commit SHA of the change to be
   merged is identified and recorded. A verdict bound to a different SHA (e.g.,
   from before a rebase or force-push) is stale and does not satisfy this gate.
2. **CI passing on that SHA** — continuous-integration checks have completed
   successfully on the exact head SHA identified above. CI failure or an
   incomplete run blocks the gate.
3. **Approved review status on that SHA** — the required review approval exists
   on the exact head SHA. A review approval on a superseded commit does not carry
   forward.

If any precondition is missing or references a different SHA, the merge gate is
**not** satisfied. The gate verdict is recorded in the delivery packet with the
SHA it was evaluated against.

Merge authority does **not** imply release authority. Passing the merge gate
authorizes landing the change — nothing more.

## Release gate

Release activity — tagging, publishing artifacts, deploying to an environment,
or announcing a release — is **separate from merge** and requires **explicit
authorization beyond merge authority**.

The release gate is satisfied only when one of the following holds:

- A **human grants release authority** for this specific change, or
- **Pre-delegated release permission** is explicitly documented (e.g., a
  release-engineering policy, a standing deployment authorization, or a
  change-manager sign-off recorded in the delivery packet).

Merge alone never satisfies the release gate. An agent that holds Merge authority
but not release authority must stop before any release activity and escalate.

### Pre-merge release readiness is not release activity

Assessing whether a change *is releasable* — version bumped, changelog updated,
migration documented, rollback plan confirmed — may occur **before** merge. This
readiness assessment does not require release authority; it is a verification
activity. However, **executing** the release (tagging, publishing, deploying) is
release activity and is gated by the release gate above.

The distinction: readiness is a judgment; release is an act. The readiness
judgment informs the release decision but does not authorize it.

---

## Stop and escalate when

- The task has **no verified need** (discovery shows no change is warranted).
- A **risk/authority boundary** requires human input (see hard stops above).
- **Two materially different approaches have failed.** Do not start an unbounded
  sequence of workarounds.
- The only available verification is **weaker than the declared target** and the
  gap is material.
- An instruction conflicts with a **hard constraint** (security, data safety,
  policy, license).

## What escalation looks like

Stop, then report in plain terms:
- What was attempted and what the evidence shows.
- The specific boundary that blocked progress.
- The decision or authority needed to proceed.
- Any safe partial result already produced.

Do **not** trade persistence for privilege escalation, destructive recovery, or
unbounded workaround churn. A clean, honest stop is a successful run.

## Recording it

Every stop, escalation, and authority decision goes in the evidence ledger —
including "no change needed" outcomes, which are legitimate results worth
preserving.

# Routing Table — Conditional Applicability Matrix

neckbeard owns the **cross-stage contracts**: the change contract, the evidence
ledger, the stop/escalation rules, and the evaluation protocol. It does **not**
own domain method. When a stage has a specialist skill, load it and follow it
instead of re-deriving its method here.

This matrix prevents the omnibus bundle from swallowing the specialist catalog.
Each row carries a concrete **applicability signal** (an observable,
file-system- or artifact-based criterion) and a concrete **skip rule** (its
observable complement). Evaluate every row against the change surface; record
each skip with its reason in the delivery packet
([delivery-packet.md](delivery-packet.md), group (e)). Silent omission is
prohibited.

**Platform neutrality.** This routing matrix works for both public OSS
repositories and private/enterprise development contexts. GitHub is a documented
reference mode, not the only possible platform. The `opensource-contributions`
row is conditional on public/OSS repositories; for private or enterprise-internal
repositories, enterprise contribution governance applies instead (see
[lifecycle.md](lifecycle.md), enterprise mode). No row assumes public-repo
defaults without qualification.

## Routing matrix

| Catalog skill | Applicability signal | Skip when | neckbeard provides |
|---|---|---|---|
| `product-discovery` | Change request text lacks testable acceptance criteria, no `SPEC.md` or requirements artifact accompanies it, or scope is contested among stakeholders | Scope is fully specified in the change request with testable acceptance criteria and no stakeholder ambiguity | Contract, ledger |
| `product-methodology` | Multiple competing requirements documents, backlog items, or priority-conflicting issues reference the same feature area; sequencing or prioritization decisions must be recorded | Requirements are singular and uncontested; no backlog, roadmap, or prioritization document needs updating | Contract, ledger |
| `product-design-and-ux` | Change creates or modifies view templates, component files, route definitions, interaction flows, information architecture, or UI-state logic | No view template, component, route definition, interaction flow, information-architecture artifact, or UI-state logic is created or modified | Contract, ledger |
| `spec-driven-development` | Work requires a formal specification with phase gates, acceptance-criteria mapping, and structured decomposition (`SPEC.md`, `TASK-PLAN.md`) | Change is a single-surface fix fully described by the change contract; no separate `SPEC.md` or phased decomposition is needed | Contract, ledger, stop rules |
| `software-architecture-analysis` | Change modifies or requires understanding of module boundaries, service dependencies (`go.mod`, `package.json` dependency graph, import graphs), cross-service contracts, or system-level structure | Change is confined to a single function or module with no cross-component dependency, service boundary, or system-level structure change | Ledger, assumptions list |
| `c4-diagramming` | Architecture change spans multiple containers or services and the design record requires system context, container, component, or code-level diagrams for review | Change fits within a single container or service; no multi-system diagram is needed for the design record | Ledger |
| `adr-authoring` | A consequential, hard-to-reverse technical decision (storage engine, framework, protocol choice) must be recorded in a decision record with context, alternatives, and consequences | No consequential decision beyond what the change contract already captures is required; no decision-record file is needed | Decision-record template, ledger |
| `api-design-and-evolution` | Change modifies or creates a public API surface: OpenAPI/AsyncAPI specs, protobuf/gRPC definitions, REST endpoints, GraphQL schema, webhook contracts, or SDK interface | No public API surface, interface contract, or protocol definition is created or modified | Contract, ledger, boundary verification |
| `systematic-debugging` | Change request reports a bug, failure, or regression; error logs, stack traces, or reproduction steps accompany it; root-cause analysis is needed before a fix can be designed | Change is not a bug fix; no error log, stack trace, or reproduction evidence accompanies the request; the desired behavior is already known | Contract, ledger, boundary verification |
| `secure-software-engineering` | Change touches auth modules, middleware handling untrusted input, secrets-management files, cryptographic operations, or code that crosses a trust boundary (e.g., `auth/`, `middleware/`, `crypto/`, input-validation handlers) | No auth module, untrusted-input handler, secrets file, crypto operation, or trust-boundary-crossing code is in the change surface | Contract, ledger, trust-boundary checks |
| `security-audit-methodology` | A security audit artifact (`SECURITY-AUDIT.md`, threat model, STRIDE analysis) is requested, or the change touches auth/crypto/trust-boundary files and a post-build vulnerability review is required | No security audit artifact is requested and the change surface does not include auth, crypto, or trust-boundary files requiring post-build review | Ledger |
| `web-accessibility` | Change modifies user-facing markup, styles, ARIA attributes, keyboard/focus contracts, or error-recovery UI; WCAG conformance is in scope | No user-facing markup, style, ARIA attribute, keyboard/focus contract, or error-recovery UI is created or modified | Ledger, non-negotiable confirmation |
| `qa-methodology` | A `VERIFICATION-PLAN.md` or test-strategy artifact is required, CI quality-gate configuration is modified, or independent verification-plan ownership is needed before implementation | Change requires no `VERIFICATION-PLAN.md`, no CI quality-gate modification, and no independent test-strategy artifact beyond the implementer's own focused tests | Ledger, boundary verification |
| `technical-documentation` | Change creates or modifies user-facing docs, README, API reference, guides, or inline documentation intended for consumers | No user-facing documentation, README, API reference, or guide is created or modified | Ledger |
| `verification-methodology` | A `VERIFICATION.md` verdict artifact with layered evidence (PASS/FAIL/BLOCKED/NOT-APPLICABLE) is required at the delivery boundary | Verification is a single focused test run that does not produce a `VERIFICATION.md` artifact or need the structured verdict protocol | Ledger, boundary rules |
| `release-engineering` | Change modifies version files, changelogs, release configuration, pipeline promotion rules, rollout strategy, or rollback procedures | No version file, changelog, release configuration, pipeline promotion rule, rollout strategy, or rollback procedure is created or modified | Contract, ledger, rollback evidence |
| `site-reliability-engineering` | Change modifies SLO/SLI definitions, incident response runbooks, operational recovery procedures, monitoring dashboards, or alerting configuration files | No SLO/SLI definition, incident runbook, operational recovery procedure, monitoring dashboard, or alerting configuration file is created or modified | Contract, ledger, rollback evidence |
| `platform-engineering` | Change modifies infrastructure-as-code, deployment pipelines, container/orchestration configuration, or platform-level provisioning files | No infrastructure-as-code, deployment pipeline, container/orchestration configuration, or platform provisioning file is modified | Contract, ledger |
| `programming-principles` | Change is primarily a refactoring (files renamed/moved/split without behavior change), code-review request, or quality assessment; diff touches many files with structural reorganization | Change is greenfield implementation or a targeted bug fix; no structural reorganization, review request, or quality assessment is the primary objective | Contract, ledger, boundary verification |
| `backend-engineering` | Change modifies server-side logic, service architecture (clean/hexagonal/layered), database access patterns, API implementation code, middleware, or service-to-service integration | No server-side logic, service architecture, database access pattern, API implementation, middleware, or integration code is modified | Contract, ledger |
| `frontend-engineering` | Change modifies client-side application code, component hierarchy, state management, browser APIs, or UI rendering logic | No client-side application code, component, state management, browser API, or UI rendering logic is modified | Contract, ledger |
| `mobile-development` | Change creates or modifies mobile app source for iOS, Android, Flutter, or React Native (`*.swift`, Kotlin sources, Flutter `lib/` Dart files, React Native components and Metro config) | No mobile app source file is created or modified; the change is web frontend or backend only | Contract, ledger |
| `documents` | A deliverable is required in office-document format (PDF, Word, Excel, PowerPoint) for human stakeholders — a report, memo, spreadsheet, or deck generated from the change | The deliverable is markdown or the repository's native format; no office-format artifact is requested | Contract, ledger |
| `cli-builder` | Change creates or modifies a command-line interface: argument parsing, flag design, subcommands, `--json` output, `--dry-run` preview, or exit-code contracts | No CLI argument parsing, flag, subcommand, or CLI output contract is created or modified | Contract, ledger |
| `data-engineering` | Change modifies database schemas, migration files (`migrations/`, `*.sql`), ETL/ELT pipelines, data quality checks, or analytical SQL | No schema, migration file, ETL/ELT pipeline, data quality check, or analytical SQL is created or modified | Contract, ledger |
| `data-architect` | Change requires a data-model design artifact, storage-platform evaluation, data-governance definition (ownership, lineage, cataloging), or cross-system data-flow diagram before implementation | No data-model artifact, storage-platform evaluation, data-governance definition, or cross-system data-flow design is required; schema changes are mechanical | Contract, ledger |
| `agent-evals-and-observability` | Change modifies AI/agent behavior: eval definitions, agent task contracts, grader bindings, trajectory fixtures, prompt templates, or agent observability/telemetry | No agent eval, task contract, grader, trajectory fixture, prompt template, or agent telemetry is created or modified | Contract, ledger |
| `opensource-contributions` | **Conditional — public/OSS repos only.** Repository remote is public, an open-source license is present, and a `CONTRIBUTING.md` or equivalent contribution governance file exists (verify via repo remote or `gh api`); contribution norms, agent disclosure, or fork etiquette apply | Repository is private or enterprise-internal (non-public remote, no open-source license); record skip as "non-public repository." Also skip when no contribution-norm question arises even in a public repo | Contract, ledger |
| `linear` | The product's tracking system was identified as Linear by [tracker-discovery.md](tracker-discovery.md) during intake, and tracker operations are needed (read/update work items, transitions, comments) | Tracking system is not Linear; or the change needs no tracker operation beyond reading provenance already captured | Contract, ledger |
| `jira` | The tracking system was identified as Jira by [tracker-discovery.md](tracker-discovery.md), and tracker operations are needed | Tracking system is not Jira; or no tracker operation is needed beyond captured provenance | Contract, ledger |
| `notion` | The tracking system was identified as Notion by [tracker-discovery.md](tracker-discovery.md), and tracker operations are needed | Tracking system is not Notion; or no tracker operation is needed beyond captured provenance | Contract, ledger |

## Test-hardening evidence

When the change is a focused regression guard for already-correct production behavior (the lightweight test-hardening path, [lightweight-test-hardening.md](lightweight-test-hardening.md)), the `qa-methodology` row supplies the evidence format: use its bounded mutation-review record ([templates/mutation-review.md](../../qa-methodology/templates/mutation-review.md)) and mutation-guided hardening methodology ([references/test-automation.md](../../qa-methodology/references/test-automation.md)) when the repository already runs mutation testing. The lightweight-path contract still governs applicability and evidence thresholds.

## Change-surface coverage

Every mandated change surface maps to at least one row above. When a change
request touches one of these surfaces, the corresponding row's applicability
signal triggers:

| Change surface | Routing row(s) |
|---|---|
| Ambiguous scope | `product-discovery`, `product-methodology` |
| User-facing behavior | `product-design-and-ux`, `frontend-engineering`, `web-accessibility` |
| Architecture | `software-architecture-analysis`, `c4-diagramming`, `adr-authoring` |
| API/interface | `api-design-and-evolution` |
| Data (schema/migration) | `data-engineering`, `data-architect` |
| Implementation domain | `backend-engineering`, `frontend-engineering`, `mobile-development`, `cli-builder` |
| Mobile app code | `mobile-development` |
| Office-format deliverables | `documents` |
| Security | `secure-software-engineering`, `security-audit-methodology` |
| AI/agent behavior | `agent-evals-and-observability` |
| Documentation | `technical-documentation` |
| Operational | `site-reliability-engineering`, `platform-engineering`, `release-engineering` |

Additional rows serve cross-cutting stages: `spec-driven-development`
(specification and decomposition), `systematic-debugging` (root-cause analysis),
`qa-methodology` (test strategy and verification planning),
`verification-methodology` (structured verdicts), and `programming-principles`
(implementation quality review).

## Multi-row composition

When several applicability signals trigger for one change (e.g., backend +
API + schema/migration), specialists **compose by stage**:

- **One lead per stage.** Each stage has exactly one lead specialist. No two
  rows own the same stage simultaneously.
- **Record per-stage leads.** The delivery packet group (e) records each
  selected skill with its stage lead — for example,
  "`backend-engineering` (lead: implementation),
  `api-design-and-evolution` (lead: contract design),
  `data-engineering` (lead: migration)."
- **Skipped rows still recorded.** Every row whose signal did not trigger is
  listed with its skip-rule reason, per the skip-transparency rule above.

## No-specialist-needed fallback

When **no** row's applicability signal triggers, work proceeds on the neckbeard
spine using the minimal stage methods in [stages.md](stages.md). The delivery
packet records: **"no specialist selected — no applicability signal triggered."**
This is a legitimate routing decision — not a silent omission and not a
fabricated skip reason.

## "Use the existing skill instead" conditions

Route entirely to a specialist — do **not** run the neckbeard spine — when:

- The task is a pure documentation job with no delivery-boundary risk →
  `technical-documentation`.
- The task is a self-contained debugging request and the user only wants the root
  cause and fix → `systematic-debugging` (neckbeard's ledger is still worth
  appending if the fix is non-trivial).
- The task is a formal spec authoring exercise → `spec-driven-development`.

## When no specialist is installed

neckbeard's [stages.md](stages.md) gives a minimal fallback method per stage.
Use it, but record in the ledger that the specialist skill was absent, so a
reviewer knows the method was the fallback rather than the full specialist.

## What neckbeard never does

- It does not re-implement a specialist's internal method.
- It does not override a repository's own contribution rules, review process, or
  human accountability.
- It does not automate privileged, destructive, deployment, or merge actions
  beyond the host agent's existing authority and confirmation controls.
- It does not treat a benchmark win as proof of production effectiveness.

# SDLC Stages

Each stage below defines **entry conditions** (what must be true to start),
**required evidence** (what you must gather or produce), **exit conditions**
(what must be true to leave), and **escalation rules** (when to stop and hand to
a human). The spine in `SKILL.md` is the order; this file is the detail.

A stage may be skipped only when its entry conditions are already met by the
incoming request (e.g. a fully-specified contract skips most of Framing). Record
every skip and why in the evidence ledger.

---

## Stage 1 — Frame the change contract

**Entry:** A request that could justify a change.

**Do:**
- State the user-visible problem in one or two sentences.
- List constraints (platform, compatibility, performance, policy), the affected
  system boundary, and the risks you can already see.
- State explicit **non-goals** — what this change will *not* do.
- Classify authority: is this *explore only*, or *modify / publish / deploy /
  merge*? When unclear, assume explore and ask.
- Decide whether any change is justified at all. "No change needed" is a valid,
  evidence-backed outcome.

**Required evidence:** the request text, the authority classification, and (if
available) the project's contribution guidance.

**Exit:** A change contract exists (use [../templates/change-contract.md](../templates/change-contract.md))
OR a documented decision that no change is warranted.

**Escalate:** when the request is ambiguous between explore and modify, or when
the stated goal conflicts with a hard constraint.

---

## Stage 2 — Discover before designing

**Entry:** A framed contract (or a documented no-change decision to confirm).

**Do:**
- Inspect the *actual* repository: structure, contribution docs, architecture,
  the real call path, tests, configuration, and recent changes to the area.
- Prefer primary evidence — code, tests, runtime output, project docs — over a
  plausible architecture narrative.
- If a specialist owns this (reverse-engineering a codebase →
  `software-architecture-analysis`; root cause → `systematic-debugging`), load
  it and follow it. Note in the ledger if the specialist was unavailable.
- Write down every unverified assumption and every access gap.

**Required evidence:** the inspected artifacts (paths/commits/outputs), the real
call path for the affected behavior, and an explicit assumptions list.

**Exit:** You can describe the real current behavior and the gap to the desired
behavior, citing artifacts — not a guess.

**Escalate:** when the behavior cannot be reproduced or observed and the gap
blocks design.

---

## Stage 3 — Select the smallest safe intervention

**Entry:** A verified understanding of current vs. desired behavior.

**Do:**
- Reuse existing code and platform capabilities first. Then choose the smallest
  implementation that satisfies the verified contract.
- Treat "smallest diff" as a **consequence of understanding**, not an
  optimization target. Do not compress to win a metric.
- **Minimalism is conditional.** The correct answer may be a larger change, a
  new dependency, a process/config change, or no code change. Pick by evidence,
  not by reflex.
- Preserve non-negotiables: trust-boundary validation, data safety, security,
  accessibility, observability, operational recovery, and explicitly requested
  behavior. Never trade these for brevity.
- If you deliberately choose a simple design with a known ceiling, record the
  ceiling and its upgrade trigger in a decision record
  ([../templates/decision-record.md](../templates/decision-record.md)).

**Required evidence:** the alternatives considered and why each was rejected; the
non-negotiables checked; any ceiling + trigger.

**Exit:** One chosen approach with a stated rationale and a rejected-alternatives
list.

**Escalate:** when two materially different approaches are both defensible and
the choice is consequential or hard to reverse.

---

## Stage 4 — Execute by stage

Route the chosen work to the stage that owns it and follow that stage's method
(load the specialist skill where one exists):

- **Discovery / requirements** → problem framing, stakeholders, acceptance
  criteria, edge cases. Specialist: `product-discovery`.
- **Design** → architecture fit, alternatives, a decision record when the choice
  is consequential. Specialist: `spec-driven-development` for formal specs;
  `product-design-and-ux` for user-facing behavior, interaction, or information
  architecture; `api-design-and-evolution` for an interface contract.
- **Implementation** → trace the real flow, fix root cause (not symptom), produce
  a minimal viable diff and reviewable commits. Specialist: `systematic-debugging`
  for bugs. For security-sensitive changes (untrusted input, auth, secrets,
  trust-boundary crossings), load `secure-software-engineering`; for accessible
  UI, load `web-accessibility`.
- **Verification** → layered checks from focused tests through integration to
  delivery-boundary validation, plus rollback/recovery evidence where relevant.
  Specialist: `verification-methodology`; `qa-methodology` for test strategy and
  regression coverage.
- **Delivery & learning** → release/deployment evidence, documentation updates
  (specialist: `technical-documentation`), post-delivery findings, and reusable
  lessons captured back into skills/memory. For reliability objectives, incident
  response, or operational recovery, load `site-reliability-engineering`.

**Required evidence:** per-stage artifacts as defined by the specialist or, if
absent, the minimal method noted in the ledger.

**Exit:** The stage's own exit conditions, plus an updated ledger.

**Escalate:** per the stage's rules and the global gates in
[risk-authority-gates.md](risk-authority-gates.md).

---

## Stage 5 — Verify at the target boundary

**Entry:** An implementation that claims to satisfy the contract.

**Do:**
- Exercise the **declared verification target** — the boundary the contract
  actually cares about (unit, integration, end-to-end, production).
- Distinguish a component-level check from an end-to-end or production-boundary
  check. State which one ran.
- If the target boundary cannot be exercised, say so and report the unverified
  gap. Do not substitute a weaker check and call it done.

**Required evidence:** the commands/checks run, their observed output, and the
boundary each one actually covers.

**Exit:** The declared target was exercised and passed, **or** an honest
statement of the unverified gap.

**Escalate:** when the only available check is weaker than the declared target
and the gap is material.

---

## Stage 6 — Deliver and learn

**Entry:** A verified (or honestly gap-declared) change with authority to deliver.

**Do:**
- Produce release/deployment evidence appropriate to the change.
- Update documentation affected by the change.
- Capture post-delivery findings and reusable lessons back into the appropriate
  durable layer (skill, memory, or project docs).

**Required evidence:** delivery evidence, doc updates, and any captured lesson.

**Exit:** Delivered with evidence, or blocked with a stated reason.

**Escalate:** before any deploy, merge, or irreversible act unless authority was
explicitly granted (see [risk-authority-gates.md](risk-authority-gates.md)).

---

## Change-request gates

When neckbeard runs the change-request journey
([journey.md](journey.md)), five explicit gates block phase
progression. Gate **numbering groups gates by area** and does **not** imply
chronological order. The execution sequence is:

> gate 1 → gate 3 → gate 2 → gate 4 → gate 5

Every gate produces a verdict recorded in the delivery packet
([delivery-packet.md](delivery-packet.md), group (h)) with the gate identifier,
verdict, evidence references, and the exact head SHA at which the verdict was
reached.

### Verdict semantics

Each gate verdict is one of three values with operational consequences:

| Verdict | Meaning |
|---|---|
| **pass** | The phase may exit and the next phase may start. |
| **conditional** | The phase may exit only with recorded conditions. Each condition is tracked and must be **closed before the next gate** is evaluated. Open conditions at the next gate are a protocol error. |
| **blocked** | The phase **may not exit**. The run stops and escalates per [risk-authority-gates.md](risk-authority-gates.md). The delivery packet transitions to the **blocked** lifecycle state (see [delivery-packet.md](delivery-packet.md), blocked-state semantics). |

### Gate 1 — Architecture/design delta approval

**Gates:** entry into phase 4 (specification and work decomposition).

The architecture delta, design decisions, risk assessment, compatibility
analysis, migration strategy, and rollback plan produced in phase 3 must be
**approved** before specification and task-planning work begins. The gate
requires an approval verdict — not merely the existence of design artifacts.

**Inputs:** architecture delta / ADR / C4 output from phase 3 (see
`software-architecture-analysis`, `adr-authoring`, `c4-diagramming` in the
[routing table](routing-table.md)).

**No-delta path:** when the change has no architecture impact, the gate is
satisfied by a **documented "no architecture delta" determination** recorded in
the packet (group (f)). The gate is never silently skipped.

**Verdict owner:** phase 3 (architecture/design delta and risk assessment).

### Gate 3 — Specification and task-plan completeness

**Gates:** exit from phase 4 (specification and work decomposition).

Chronologically the second gate. Planning may not complete until:

- `SPEC.md` exists with acceptance criteria **mapped to the change contract**;
- at least one acceptance criterion traces to the requester's stated
  outcome/problem restated from primary evidence in phase 2 — verification
  proves the build matches the spec; this criterion proves it solves the
  requester's actual problem (15288/12207 validation vs. verification
  discipline);
- `TASK-PLAN.md` covers **every** spec item and acceptance criterion;
- no task is unbounded (missing effort/scope estimate) or ownerless (no
  assigned phase or specialist).

**Inputs:** `SPEC.md` and `TASK-PLAN.md` produced under
`spec-driven-development` (see [routing table](routing-table.md)).

**Verdict owner:** phase 4. The verdict is recorded **before** the planning
phase exits.

### Gate 2 — QA-owned test and verification plan

**Gates:** entry into phase 6 (domain-specific implementation).

Chronologically the third gate. A test strategy and verification plan must
exist and be approved **before implementation begins**.

**Operational rule:** no implementation work — code edits, commits, or
branch work beyond the packet — may occur until the QA-plan verdict is
recorded in the packet. "Implementation begins" means the first
implementation-phase commit or edit, not planning discussion.

**Inputs:** `VERIFICATION-PLAN.md` naming verification targets, test levels
(unit / integration / end-to-end), regression coverage strategy, and the
evidence artifacts that constitute a passing verification.

**Verdict owner:** phase 5 (pre-implementation test and verification
planning). The plan is produced under `qa-methodology`
(see [routing table](routing-table.md)), establishing independence between
planning and execution. Post-hoc self-approval by the implementer is not
permitted.

**No-new-tests path:** when the change requires no new tests (e.g., a
docs-only change), that determination is documented with a reason in the
packet rather than silently omitting the gate.

**Distinction:** this gate checks the **plan's** existence and adequacy, not
the test results — those are produced later under gate 5.

### Gate 4 — Independent review

**Gates:** exit from phase 7 (independent review and boundary verification).

Chronologically the fourth gate. An independent review covering qualities
**not captured by the specification** — this is **not** a spec-compliance
re-check. Spec compliance is verified at gate 3; gate 4 verifies
maintainability, security posture, accessibility conformance, documentation
clarity, and architectural coherence.

**Per-dimension reviewer mapping:**

| Review dimension | Specialist(s) |
|---|---|
| Code quality | `programming-principles` |
| Architecture consistency | `software-architecture-analysis` + `c4-diagramming` |
| Security | `secure-software-engineering` / `security-audit-methodology` |
| Accessibility | `web-accessibility` |
| Documentation | `technical-documentation` |

**Per-dimension coverage:** the review verdict records which dimensions were
covered and, for any dimension that is out of scope for the change, a
documented reason (e.g., "accessibility: out of scope — no user-facing
markup modified"). A reviewer can determine from the verdict both who
reviewed each dimension and whether each was covered.

**Verdict owner:** phase 7. The verdict is **distinct** from the
spec-compliance verdict at gate 3; a completed packet shows two separate
verdicts.

### Gate 5 — Boundary verification

**Gates:** final acceptance (phase 8 readiness).

Chronologically the fifth gate. Boundary verification exercises the declared
verification target (unit, integration, end-to-end, or production boundary)
after implementation is complete.

**Re-verification after material change:** any material review-driven change
invalidates the prior verification verdict and requires re-verification. The
verification verdict is bound to the **exact head SHA** at the time it was
performed; a verdict bound to a stale SHA does not satisfy this gate. For
gate satisfaction, the verdict SHA must equal the final head SHA.

**Material change definition (canonical).** This is the single source of
truth for materiality referenced by [journey.md](journey.md),
[lifecycle.md](lifecycle.md), and
[delivery-packet.md](delivery-packet.md):

- **Material** (invalidates prior verdicts, requires re-verification):
  a change that alters logic, adds or removes functionality, modifies the
  verification surface, changes test assertions, or alters data flow across
  a trust boundary.
- **Non-material** (prior verdicts stand; SHA binding updated):
  typo fixes, formatting-only changes, comment-only edits, pure renames
  without behavior change, docs-only changes, and rebases that produce no
  semantic diff.

After a **non-material** change, the recorded head SHA in the packet is
updated to the current SHA and the update itself is logged (old SHA → new
SHA, materiality: non-material). Prior verdicts are not re-run. After a
**material** change, affected gates re-run and new verdicts are bound to the
new head SHA.

**Verdict owner:** phase 7 (initial verification); re-verification after
material review-driven changes re-enters phase 7.

---

## Delivery paths

Four named paths determine which of the nine journey phases are mandatory
and which are conditional. **This section is the single source of truth for
path/phase matrices**; [journey.md](journey.md) references these definitions
rather than maintaining its own copy.

Path selection is recorded in the delivery packet (group (b)). When a
conditional phase is skipped, the skip is recorded in the packet (group (e))
with a concrete reason citing the path rule — silent omission is prohibited
(see [delivery-packet.md](delivery-packet.md), skip transparency).

### Phase reference

The nine journey phases (see [journey.md](journey.md) for full definitions):

1. Intake and provenance
2. Current-state discovery and reproduction
3. Architecture/design delta and risk assessment
4. Specification and work decomposition
5. Pre-implementation test and verification planning
6. Domain-specific implementation
7. Independent review and boundary verification
8. Readiness, CI/review loops, exact-final-head re-verification
9. Authorized post-merge release and closeout

### Path matrices

| Phase | Lightweight | Full | Refactor | High-risk |
|---|---|---|---|---|
| 1 — Intake and provenance | **mandatory** | **mandatory** | **mandatory** | **mandatory** |
| 2 — Discovery and reproduction | conditional | **mandatory** | **mandatory** | **mandatory** |
| 3 — Architecture/design delta | conditional | **mandatory** | **mandatory** | **mandatory** |
| 4 — Specification and decomposition | conditional | **mandatory** | conditional | **mandatory** |
| 5 — Test and verification planning | conditional | **mandatory** | conditional | **mandatory** |
| 6 — Implementation | **mandatory** | **mandatory** | **mandatory** | **mandatory** |
| 7 — Review and boundary verification | **mandatory** | **mandatory** | **mandatory** | **mandatory** |
| 8 — Readiness and re-verification | **mandatory** | **mandatory** | **mandatory** | **mandatory** |
| 9 — Release and closeout | **mandatory** | **mandatory** | **mandatory** | **mandatory** |

### Lightweight path

For narrow, low-risk changes (single-surface bug fix, test-hardening regression
guard, docs-only change, or config tweak). Mandates phases 1, 6, 7, 8, 9.

Test-hardening is a named lightweight subtype. Use it only when production
behavior is already correct, production/runtime code remains unchanged, and a
focused test plus a bounded controlled weakening can expose the regression. Its
specific evidence and escalation rules are in
[lightweight-test-hardening.md](lightweight-test-hardening.md).

**Dropped phases with skip criteria:**

| Dropped phase | Skip criterion |
|---|---|
| 2 — Discovery and reproduction | The change surface is a single function or module and the current behavior is already understood from the change request; no reproduction is needed. For the test-hardening subtype, record the clean behavior and named mutation or controlled weakening instead of requiring a live production repro. |
| 3 — Architecture/design delta | No module boundary, service dependency, cross-component contract, or system-level structure is affected (per the `software-architecture-analysis` skip rule in the [routing table](routing-table.md)). |
| 4 — Specification and decomposition | The change is fully described by the change contract with testable acceptance criteria; no separate `SPEC.md` or phased decomposition is needed (per the `spec-driven-development` skip rule). |
| 5 — Test and verification planning | No `VERIFICATION-PLAN.md` is required beyond the implementer's own focused tests; the change introduces no new verification surface (per the `qa-methodology` skip rule). |

Each skip is recorded with its criterion in packet group (e). Gates 1, 3,
and 2 are conditional on this path (skipped with their phases); gates 4 and
5 remain mandatory. Gate 4 may be satisfied by one bounded final review after
the candidate is frozen, or by the repository's required platform review; a
second long-running reviewer is not implied by the lightweight path.

### Lightweight test-hardening variant

The test-hardening variant applies when a mutation, coverage gap, or controlled
weakening exposes a missing regression guard while the clean production behavior
is already correct.

Its gate 5 evidence is:

- the clean baseline passes;
- the named mutant or controlled weakening fails the new test;
- the test exercises the public contract with hermetic setup at the relevant
  failure boundary; and
- focused tests, lint, compilation, scope, and changed-file security checks pass.

The ordinary production-bug rule that a new test must fail on clean `main` does
not apply. The variant does not require a broad mutation campaign, a full
architecture/specification packet, or a full-repository scan unless another
trigger surface applies. For expensive CI, those local checks are completed
before the first push so the remote run verifies a stable candidate.

### Full path

For standard feature work. **All nine phases are mandatory.** All five gates
apply. No phase may be skipped.

### Refactor path

For behavior-preserving structural changes (rename, extract, reorganize).
Mandates phases 1, 2, 3, 6, 7, 8, 9 — discovery and architecture review are
always required to confirm behavior preservation.

**Conditional phases:**

| Conditional phase | Skip criterion |
|---|---|
| 4 — Specification and decomposition | The refactor is fully characterized by the architecture delta and characterization-test plan; no separate `SPEC.md` is needed because no behavior changes. |
| 5 — Test and verification planning | Existing characterization tests cover the affected surface and no new verification plan is needed; the test strategy is recorded as "existing suite, no additions." |

Gates 1, 4, and 5 are always mandatory on this path. Gates 3 and 2 are
conditional (skipped only with their phases, with recorded reasons).
Behavior-preservation evidence (characterization tests passing before and
after) is the gate 5 criterion.

### High-risk path

For changes with safety, security, compliance, or production-criticality
concerns (schema migrations, trust-boundary changes, SLO-affecting work).
**All nine phases are mandatory. All five gates apply with no conditional
skips.** No phase or gate may be skipped regardless of apparent scope.
Escalation review is required at gate 1, gate 2, and gate 5 boundaries.

# Tracker Discovery — Tracker-Neutral Intake

The change-request journey is defined in tracker-neutral terms: *work item*,
*state transition*, *review submission*, *merge or acceptance into the protected
target*, *release authorization*. Platform mechanics belong to the layer that
operates the platform — the routing rows in
[routing-table.md](routing-table.md) and the platform reference modes
([lifecycle.md](lifecycle.md)) — not to the spine itself.

That separation only works if intake actually establishes which tracking system
the product uses. This reference defines that sub-step of phase 1
([journey.md](journey.md), Intake and provenance). It exists because
improvisation under ambiguity defaults to whatever platform the agent knows
best, and the correct answer is detection plus an explicit question, not a
default.

## The rule

**Never assume the tracking system.** Detect it from repository evidence where
possible; ask the requester when evidence is absent or contradictory; record
the finding and its basis in delivery packet group (a) before any tracker
operation runs.

Read-only identification is discovery and needs no confirmation. The first
mutation against the detected system still passes the normal state-change gate
([risk-authority-gates.md](risk-authority-gates.md)).

## Detection procedure

Run during phase 1 alongside provenance capture:

1. **Inspect remotes and configuration** for tracking-system fingerprints:

| Signal | Points to |
|---|---|
| Issue/ticket URLs referenced by the change request (`…/issues/N`, `…/TICKET-123`, Linear `…/issue/TEAM-N`, Notion `notion.so`/`notion.site` page links) | GitHub Issues / Jira / Linear / Notion respectively |
| `.jira-url`, Jira config files in the repository | Jira — weak signal: requires corroboration before it alone selects Jira (see step 3) |
| Team keys in ticket identifiers (`ENG-42` shape) with a non-GitHub tracker configured | Jira or Linear — ambiguous between them |
| Project-management config directories (for example `.linear/`) or documented integrations in `CONTRIBUTING.md`, `AGENTS.md`, README | Whatever they name — weak signal: requires corroboration (see step 3) |

2. **Check what the request itself references — and who authored the
   reference.** A change request arriving as a Linear issue URL, a Jira issue
   URL, a GitHub issue number, or a Notion page link (`notion.so` /
   `notion.site`) stated **by the requester directly, from the requester's own
   knowledge** is strong evidence for its own system. A bare team-key
   identifier (`ENG-42` shape) is
   **ambiguous** between Jira and Linear — treat it as a lead, not a verdict.
   Two weaker cases require corroboration before they alone select a system:
   a reference inherited from prior-work handoff material (a handoff note,
   branch docs, comments left by the contributor who produced an adopted
   branch), and a reference the requester merely relays out of that handoff
   material ("continue the ticket the contractor left") — the requester's
   words do not launder the producing party's claim. Treat both under step 3
   like any other weak signal.

3. **Weight the signals honestly.** References stated by the requester from
   the requester's own knowledge are strong evidence. Repository content —
   `CONTRIBUTING.md`, `AGENTS.md`,
   README integrations, config files like `.linear/` or `.jira-url` — is a
   **weak signal**: it describes what the repository documents, not necessarily
   what holds authoritative work items, and it is attacker-influenceable in
   mid-flight or adopted-branch scenarios where this bundle also operates.
   Inherited references and repository signals require corroboration (remote
   configuration, or requester confirmation independent of the handoff)
   before they alone select a system.

4. **Ask when ambiguous or absent.** If signals conflict, rest only on weak
   signals, or none exist, ask one bounded question: which system holds this
   work item? Record the answer as requester-provided provenance. Do not
   silently pick the system whose CLI happens to be installed.

5. **Record the findings:** detected/requested system with the evidence or
   source of the answer (including when the basis is a requester confirmation)
   goes in packet group (a) as provenance; the routing decision — which tooling
   skill will operate tracker operations — is a specialist-selection decision
   and is recorded in packet group (e), same as every other selected or skipped
   skill. Silent omission is prohibited like every other intake field.

## Routing tracker operations

Operate the detected system through its catalog tooling skill rather than
improvising API calls:

| Detected system | Route operations to |
|---|---|
| GitHub (issues, PRs, releases) | Native mechanics per [lifecycle.md](lifecycle.md) — the documented reference mode |
| Linear | `linear` |
| Jira | `jira` |
| Notion | `notion` |
| Other / none of the above | No specialist route: operate only through the system's verified official interface (primary vendor documentation, confirmed endpoint/auth surface), with bounded reads; note the absent specialist in the ledger |

Routing constraints:

- Every named routing target must be a real skill in this catalog; dead links
  are a defect. If a target is missing from an installation, proceed on the
  fallback and record the absence — same convention as
  [routing-table.md](routing-table.md) § When no specialist is installed.
- Tooling skills are mechanical layers. They own commands and API contracts;
  the journey owns sequencing, and discipline specialists own judgment. No
  tracker skill becomes a second orchestrator.
- Vocabulary crossing the boundary stays neutral: a "state transition" maps to
  whichever transition the target system defines (workflow state move, label
  change, status update); the packet records outcomes by neutral name.

## Non-goals

- This step does not migrate content between systems or reconcile divergent
  trackers. If work items exist on two systems, surface the conflict at intake
  and ask which is authoritative.
- It does not change credential handling. Each tooling skill's own setup rules
  apply.
- It does not make the journey depend on any single vendor. Absence of a
  tracker, or use of an unrouted system, degrades gracefully to the fallback
  path.

# Nine-Phase Change-Request Journey — Validation Against Established SDLC Models and Agentic-Workflow Frameworks

| Field | Value |
|---|---|
| **Issue** | #372 (research only — no neckbeard behavior changes proposed here) |
| **Date** | 2026-08-22 |
| **Subject studied** | `neckbeard/references/journey.md` at commit `04a9b60b58244b5007e9279d53ed504362303320` (`git log -1 --format=%H -- neckbeard/references/journey.md`), branch `research/neckbeard-journey-sdlc-validation`, based on `origin/main`. Supporting context: `neckbeard/SKILL.md` core loop, `neckbeard/references/stages.md` § Stage 6 and § Change-request gates, `neckbeard/references/risk-authority-gates.md` stop rules. |
| **Comparison basis** | Four established lifecycle/process models (ISO/IEC/IEEE 15288:2023, ISO/IEC/IEEE 12207:2017, CMMI-DEV V1.3, ITIL 4 service value system) and three published agentic-workflow approaches (Anthropic "Building Effective Agents", OpenAI "A Practical Guide to Building Agents", the Agent Skills specification). |
| **Method** | research-methodology skill, academic/comprehensive track (Scope → Gather → Evaluate → Analyze → Synthesize → Report). Companion evidence log: [journey-sdlc-validation-log.md](journey-sdlc-validation-log.md). All access dates 2026-08-22. |
| **Doctrine lens** | Every verdict below is judged against neckbeard's stated doctrine: evidence over assertion, smallest safe intervention, and hard authority boundaries (readiness ≠ release; merge authority ≠ release authority). |

---

## Research questions (restated from issue #372)

1. **RQ1 — Missing counterparts.** Do established lifecycle models contain phases or feedback loops with NO counterpart in the nine-phase journey? Specifically examined: maintenance/operations feedback into planning, post-release learning loops, retirement/decommission stages.
2. **RQ2 — Agentic workflow structures and authority gates.** How do published agentic-workflow approaches structure multi-stage software delivery, and where do they place human authority gates relative to neckbeard's five gates?
3. **RQ3 — Phase boundaries.** Are the phase boundaries themselves right — anything merged that should be split, or split that should be merged?
4. **RQ4 — Verdicts.** For each material difference: adopt, adapt to neckbeard's evidence-first doctrine, or reject, with rationale.

## Part 1 — Per-framework mapping

### 1.1 ISO/IEC/IEEE 15288:2023 — System life cycle processes

Primary: ISO catalog entry, https://www.iso.org/standard/81702.html (accessed 2026-08-22); IEEE SA, https://standards.ieee.org/ieee/15288/10424/ (accessed 2026-08-22). Clause inventory corroborated via https://en.wikipedia.org/wiki/ISO/IEC_15288 (accessed 2026-08-22). Full normative text is paywalled; see log § limitations.

The standard defines 30 processes in four categories (agreement; organizational project-enabling; technical management; technical). The fourteen technical processes include, in order: business/mission analysis, stakeholder needs and requirements definition, system requirements definition, architecture definition, design definition, system analysis, implementation, integration, verification, transition, validation, **operation**, **maintenance**, **disposal**.

| 15288 element | Nine-phase journey counterpart | Notes |
|---|---|---|
| Stakeholder needs & requirements definition (6.4.2), System requirements definition (6.4.3) | Phases 1, 4 | Intake captures provenance, authority, conventions, linked work; phase 4 produces SPEC.md with acceptance criteria mapped to the change contract. Deep stakeholder elicitation is handled by the phase-4 escalation path (product-discovery), not a dedicated phase. |
| Architecture definition / Design definition (6.4.4–6.4.5) | Phase 3 (+ gate 1) | Direct counterpart including decision records and rejected alternatives. |
| System analysis (6.4.6) | Phase 3 risk assessment | Risks, compatibility, migration, rollback plan are mandatory phase-3 outputs. |
| Implementation (6.4.7) | Phase 6 | Direct. |
| Integration (6.4.8) | Phases 6–8 | Branch/CI mechanics; exact-final-head SHA binding. |
| Verification (6.4.9) | Gates 2 and 5; phases 5, 7 | Pre-planned QA-owned verification plan plus boundary verification at the declared target. Stronger than most implementations of 15288 because the verification plan precedes implementation. |
| Validation (6.4.11) | Partial — gate 4 review + acceptance criteria | Confirming the change serves stakeholder intent is implicit in acceptance criteria and the issue thread; there is no named validation step distinct from verification. See Finding F4. |
| Transition (6.4.10) | Phases 8–9 | Merge/release = transition into the protected target; release gate ≈ transition authorization. |
| **Operation (6.4.12)** | **None** | Journey stops at post-release smoke check evidence. Operational monitoring/feedback is outside the single change request. Finding F1. |
| **Maintenance (6.4.13)** | **None as a phase — structurally absorbed** | Each subsequent issue/ticket starts a new journey; the journey *is* the unit of maintenance under 12207-style taxonomies. There is no explicit "feed operations learnings into the next planning cycle" loop inside one journey. Findings F1, F2. |
| **Disposal (6.4.14)** | **None** | Retirement/decommissioning has no counterpart. Finding F3. |
| Technical-management processes (risk, decision, config mgmt, QA, assessment/control) | Distributed across all phases | Head-SHA binding + materiality rule ≈ configuration management; escalation/stop rules ≈ decision management; gate verdict ledger ≈ project assessment and control. |

**Authority-gate placement:** 15288 locates authority in organizational processes (agreement, project assessment and control) and does not prescribe where human sign-off occurs within a change. The journey is far more prescriptive: five named gates, authority classes at intake, and a hard separation of readiness (phase 8) from release (phase 9). This is a tightening, not a contradiction.

### 1.2 ISO/IEC/IEEE 12207:2017 — Software life cycle processes

Primary: ISO catalog entry, https://www.iso.org/standard/63712.html (accessed 2026-08-22). Process-category structure corroborated via arc42 quality-model summary, https://quality.arc42.org/standards/iso12207 (accessed 2026-08-22). Normative text paywalled.

12207 organizes software life-cycle activity into agreement, organizational project-enabling, technical-management, and technical process categories; the technical processes span stakeholder requirements through implementation, integration, verification, validation, operation, **maintenance** (including corrective, adaptive, perfective, preventive maintenance), and **disposal**.

Key analytical result: **the nine-phase journey is best classified as 12207's maintenance-and-development technical processes instantiated per change request.** Under 12207, corrective/perfective maintenance activity flows through the same requirements → design → implementation → verification pipeline; the journey models exactly that pipeline for one change, entered from an issue (the maintenance trigger). What 12207 adds that the journey lacks inside one journey instance:

| 12207 element | Journey counterpart | Notes |
|---|---|---|
| Agreement processes | Phase 1 authority class + change contract | Close functional match: the change contract records who authorized what class of work. |
| Life-cycle model management / tailoring | Delivery paths (lightweight/full/refactor/high-risk) with recorded skips | Tailoring with mandatory skip-reason recording exceeds typical tailoring guidance (silent omission prohibited). |
| Verification / Validation | Gates 2, 4, 5 | Same verification-vs-validation asymmetry as 15288. Finding F4. |
| **Operation / Maintenance feedback** | None inside one journey; next journey is the vehicle | Finding F1/F2. |
| **Disposal** | None | Finding F3. |

**Authority-gate placement:** 12207 permits combined development/assurance roles unless the acquirer constrains them; the journey independently mandates reviewer-implementer separation (gate 4 "distinct from spec-compliance checking"; QA-owned gate 2 "post-hoc self-approval by the implementer is not permitted"). Tightening, consistent.

### 1.3 CMMI for Development, Version 1.3 (CMU/SEI-2010-TR-033)

Primary: full SEI technical-report text consulted via public reproduction at http://cmmis.free.fr/cmmi-dev/text/index.php (unofficial mirror of CMU/SEI-2010-TR-033; content verified against report front matter, accessed 2026-08-22). Official alternate locations identified but not fetched: https://apps.dtic.mil/sti/tr/pdf/ADA532839.pdf, CMU Kilthub record.

CMMI-DEV organizes 22 process areas across staged maturity levels. Engineering category: Requirements Development (RD), Technical Solution (TS), Product Integration (PI), Verification (VER), Validation (VAL). Support: Configuration Management (CM), Process and Product Quality Assurance (PPQA), Measurement and Analysis (MA), Decision Analysis and Resolution (DAR), **Causal Analysis and Resolution (CAR, level 5)**.

| CMMI-DEV PA | Journey counterpart | Notes |
|---|---|---|
| RD / REQM | Phases 1, 4 | Requirements developed and managed against the change contract. |
| TS | Phases 3, 6 | Design alternatives evaluated and recorded (rejected alternatives are mandatory phase-3 output) — mirrors TS SP 1.1/1.2 and DAR-style selection criteria. |
| PI | Phases 6–8 | Build/integration with CI as boundary evidence. |
| VER | Gates 2, 5; phase 5 | Peer-review + verification practices; journey's pre-implementation test planning matches VER SG 1 intent. |
| VAL | Partial — gate 4 + acceptance criteria | Same verification/validation asymmetry. Finding F4. |
| CM | Packet group (c)/(h) head-SHA binding; materiality rule | The exact-final-head re-verification and material/non-material classification are a disciplined CM baseline-and-change mechanism. |
| PPQA | Gate 4 independent review; QA-owned gate 2 | PPQA requires assurance by someone not producing the work product — the journey's independence doctrine matches this precisely. |
| DAR | Phase-3 decision records; escalation when two defensible approaches diverge | Direct match. |
| RSKM | Phase-3 risk assessment; high-risk path | High-risk path adds escalation review at gates 1, 2, 5 — proportional risk management. |
| MA | CI status, gate-verdict ledger, packet groups | Evidence-first doctrine institutionalizes measurement. |
| **CAR** | **No journey counterpart** | CMMI's formal post-defect causal-analysis loop (select defect data → root-cause → propose/implement actions) lives at organizational level. Its nearest in-repo analogue is core-loop Stage 6 "Deliver and learn," which is NOT wired into the nine-phase journey's phase 9 outputs. Finding F2. |

**Authority-gate placement:** CMMI embeds authority in institutionalized process (GP 2.9/2.10, PPQA separation) rather than per-change human gates. The journey's explicit gates are compatible and more granular for agentic execution.

### 1.4 ITIL 4 service value system

Sources: InvGate ITIL 4 SVS explainer, https://invgate.com/itsm/itil/service-value-system (accessed 2026-08-22); practitioner analysis of the service value chain by D. Breston, https://itsm.tools/itil-4-service-value-chain/ (accessed 2026-08-22; also documents the January 2026 ITIL Version 5 announcement). PeopleCert/Axelos normative text is licensed and was not directly accessible; see log § limitations.

The SVS comprises guiding principles, governance, 34 practices, continual improvement, and the six-activity service value chain: **plan, improve, engage, design & transition, obtain/build, deliver & support**.

| SVC activity | Journey counterpart | Notes |
|---|---|---|
| Engage | Phase 1 intake; phase 7 review engagement; phase 9 enterprise CAB | Partial. Stakeholder dialogue beyond intake/review (value confirmation with users) is absent. |
| Plan | Phases 4–5 | Spec + task plan + verification plan. |
| Design & transition | Phases 3, 7, 8, 9 | Includes enterprise-mode CAB/change-manager sign-off and change-freeze compliance — direct ITIL change-enablement mapping already present in phase 9. |
| Obtain/build | Phase 6 | Direct. |
| Deliver & support | Phase 9 (deliver only) | Release evidence, smoke check. Ongoing support/operations is out of journey scope. Finding F1. |
| **Improve (continual improvement)** | **No journey counterpart** | ITIL treats improvement as built into the system ("improvement isn't a side project"). The journey declares phase 9 output "terminal; not consumed," so nothing in the journey itself carries lessons forward — although core-loop Stage 6 does. Finding F2. |

**Authority-gate placement:** ITIL's change-enablement practice routes changes through a change authority (CAB/change manager) sized to risk — the journey's enterprise mode already maps this onto the phase 9 release gate, and its GitHub mode separates merge from release authorization in exactly the ITIL sense of delegated change authority. Convergent; no change indicated.

*Currency caveat:* ITIL Version 5 was announced in January 2026, replacing the service value chain with a "digital product and service lifecycle" while keeping the rest of the SVS largely unchanged. The continual-improvement finding (F2) is expected to survive that revision, but revalidation is warranted once published.

### 1.5 Anthropic, "Building Effective Agents" (Dec 19, 2024)

Primary first-party engineering publication: https://www.anthropic.com/engineering/building-effective-agents (accessed 2026-08-22).

Structures for multi-stage delivery: augmented LLM building block; workflows (prompt chaining with programmatic "gates", routing, parallelization sectioning/voting, orchestrator-workers, evaluator-optimizer); autonomous agents with environment ground-truth at each step, checkpoint pauses for human input, and stopping conditions.

| Anthropic construct | Nine-phase journey counterpart |
|---|---|
| Prompt chaining with programmatic checks ("gates") between steps | Five gates blocking phase progression — same shape, made explicit and auditable. |
| Routing | Conditional specialist routing via routing-table.md; four delivery paths select the route at intake. |
| Parallelization / voting | Multi-dimension independent review at gate 4 (code quality, architecture, security, accessibility, docs) — several reviewers over one frozen candidate. |
| Orchestrator-workers | Specialist composition with one recorded lead per stage (packet group (e)). |
| Evaluator-optimizer loop | Phase 7 → phase 8 CI/review feedback iteration, bounded by the materiality rule (material change ⇒ re-enter phase 7). |
| "Gain ground truth from the environment at each step" | Evidence-ledger doctrine: files changed, commands run, observed outputs appended per phase. |
| Stopping conditions / max iterations | Bounded loops: escalation after two undiagnosable CI failures; stop after two materially different approaches fail; timed-out review is inconclusive and does not restart against a mutable candidate. |

**Human authority-gate placement:** Anthropic places human involvement at task initiation ("command from, or interactive discussion with, the human user"), at checkpoints, and on blockers — leaving gate placement to the implementer. For coding specifically it concludes automated tests verify functionality but "**human review remains crucial** for ensuring solutions align with broader system requirements." The journey agrees and goes further: authority classes at intake, escalation stop rules at every boundary, and separate merge/release authorization. **Convergence, with neckbeard strictly more prescriptive.**

**Doctrinal alignment:** Anthropic's core counsel — simplest solution possible, add complexity only when demonstrably justified — is the same judgment as smallest safe intervention, and the four delivery paths operationalize it proportionally.

### 1.6 OpenAI, "A Practical Guide to Building Agents" (April 2025)

Primary first-party guide (PDF): https://cdn.openai.com/business-guides-and-resources/a-practical-guide-to-building-agents.pdf (downloaded and converted locally; accessed 2026-08-22).

Structures: foundations (model + tools + instructions); a "run" loop until an exit condition; orchestration via single agent, manager pattern, or decentralized handoffs; layered guardrails; explicit human-intervention design.

| OpenAI construct | Nine-phase journey counterpart |
|---|---|
| Run loop with exit conditions | Core-loop spine; journey phases bound each run. |
| Manager pattern / decentralized handoffs | Orchestrating SKILL.md loads journey reference; specialists routed per phase. |
| Layered guardrails (input, tool, output) | Gate stack + stop rules + skip transparency. |
| **Tool safeguards:** rate each tool low/medium/high by read-only vs write access, reversibility, required permissions, financial impact; **pause before high-risk functions or escalate to a human** | Authority classes (explore/modify/release) + risk-authority-gates.md hard stops (never delete data/branches/releases/infra without directive; never escalate privileges; never deploy/merge without granted authority). Same principle, coarser per-call granularity. Finding F6. |
| **Human-intervention trigger 1: exceeding failure thresholds** | Escalation after two failed diagnostic attempts; stop after two materially different failed approaches. Matches. |
| **Human-intervention trigger 2: high-risk, sensitive, irreversible, or high-stakes actions** | Hard stops on irreversible/trust-boundary acts; release gate. Matches. |

**Human authority-gate placement relative to neckbeard's gates (RQ2):** both vendors converge on the same three placements the journey already encodes — upfront authorization scoping, threshold-based escalation, and mandatory human oversight of consequential/irreversible actions. Neither vendor structures software delivery into SDLC phases; their guidance is runtime-architecture advice. The journey therefore occupies complementary territory: it supplies the lifecycle sequencing and auditability those guides leave undefined. No conflicting recommendation found.

### 1.7 Agent Skills specification (agentskills.io)

Primary specification: https://agentskills.io/specification.md (accessed 2026-08-22).

The Agent Skills format packages capabilities (SKILL.md + optional scripts/references/assets) with progressive disclosure and an experimental `allowed-tools` pre-approval field. It contains **no lifecycle phases, no gates, and no workflow semantics** — it is a capability-packaging layer, orthogonal to process models.

Relevance: neckbeard is itself structured per this format, loads the journey as a conditionally-loaded reference, and routes phase work to packaged specialist skills. The spec's static `allowed-tools` grant is a blunter instrument than the journey's authority classes; the journey's approach (authority bound to the change contract and re-examined at gates) is stronger for change delivery. No restructuring indicated.

## Part 2 — Findings and verdicts

Confidence: H = triangulated across ≥3 independent sources; M = 2 sources or single-source-on-secondary-point.

| # | Material difference | Sources | Confidence | Verdict | Rationale grounded in neckbeard doctrine |
|---|---|---|---|---|---|
| **F1** | **Post-release operations and monitoring have no journey counterpart.** 15288 defines Operation (6.4.12) and Maintenance (6.4.13) as technical processes; ITIL's deliver & support extends past release. The journey ends at phase 9 with release evidence and a terminal packet. | 15288; 12207; ITIL 4 | H | **ADAPT (minimal)** | Do not add a phase 10 — that would violate smallest safe intervention and duplicate `site-reliability-engineering`/`release-engineering` competencies the routing table already reaches. Adapt instead: phase 9 closeout should record **rollback/follow-up triggers** (already a core-loop obligation, SKILL.md step 5) alongside release evidence, and route operational discoveries to a *new* change request via phase 1 intake. Evidence-first: the terminal record then states what would cause re-entry. |
| **F2** | **Post-release learning loop is mandated by the core loop but not wired into the journey.** ITIL makes continual improvement structural; CMMI CAR formalizes post-defect causal analysis; neckbeard's own stages.md Stage 6 ("Deliver and learn") requires capturing "post-delivery findings and reusable lessons… back into the appropriate durable layer." Yet journey phase 9's required outputs are only terminal state + release/close evidence, and the phase-continuity table marks phase 9 output "terminal; not consumed." This is an internal misalignment between journey.md and stages.md, not just an external gap. | ITIL 4; CMMI-DEV CAR; neckbeard stages.md (internal) | H | **ADAPT** | Extend phase 9 closeout outputs to include a lesson-capture field with skip transparency: either the captured lesson(s) and their durable destination, or an explicit "no reusable lesson identified" determination — mirroring how skipped phases/specialists must be recorded with reasons. Small diff, restores consistency with the skill's own Stage 6 doctrine, preserves terminal-state semantics. |
| **F3** | **Retirement/decommissioning has no journey counterpart.** 15288 Disposal (6.4.14) and 12207 disposal address retiring systems. Nothing in the nine phases covers decommissioning. | 15288; 12207 | H | **REJECT (deliberate scope boundary)** | The journey governs individual change requests, not asset lifecycles. Decommissioning enters as what it is — a high-risk change request (path selection already forces all nine phases, all five gates, no skips) whose irreversibility is caught by existing hard stops ("never delete data, branches, releases, or infrastructure without an explicit human directive"). Adding a retirement phase would conflate change-delivery scope with portfolio-level lifecycle management. Record the boundary in docs if desired; do not add phases. |
| **F4** | **Validation is under-distinguished from verification.** 15288 separates verification (product reflects specified requirements) from validation (product fulfills stakeholder need in intended use), as does CMMI VER vs VAL. The journey has strong verification (gates 2/5, declared boundary targets) and independent review (gate 4), but confirming the change solves the *requester's actual problem* rides only implicitly on acceptance-criteria mapping in phase 4. | 15288; 12207; CMMI-DEV | H | **ADAPT** | Make requester-outcome traceability explicit at gate 3: SPEC.md acceptance criteria already map to the change contract; require that at least one criterion traces to the requester's stated outcome/problem restated in phase 2 (which is already mandatory primary-evidence work). Zero new phases; strengthens evidence-over-assertion where it is thinnest — did we build what was actually asked for? |
| **F5** | **Stakeholder-needs elicitation is not a phase.** 15288 6.4.2 and 12207 treat stakeholder-needs definition as first-class. The journey assumes the change request arrives with adequate intent and handles ambiguity reactively (phase 4 escalation to product-discovery). | 15288; 12207 | M | **REJECT** | Proactive elicitation as a standing phase would penalize the lightweight path and contradict smallest safe intervention; the reactive escalation plus the phase-2 mandatory restatement-from-primary-evidence covers the failure mode at lower ceremony. Revisit only if intake-quality data shows repeated late discovery of misunderstood requests. |
| **F6** | **Per-tool risk rating granularity.** OpenAI recommends rating each agent tool by write-access/reversibility/permissions and pausing before high-risk calls. The journey grants authority by class per change rather than per tool. | OpenAI guide; contrast neckbeard risk-authority-gates.md | M | **REJECT (for now)** | Per-tool ratings would duplicate risk-authority-gates.md stop rules and routing-table contracts at finer grain than decisions actually occur, adding ceremony without adding evidence. The authority-class model binds permission to the *change*, which is where accountability lives. Plausible future refinement for enterprise mode only; file as open question, not a defect. |
| **F7** | **Gate placement converges with published agentic practice.** Both Anthropic (checkpoints, blockers, human review essential for code) and OpenAI (failure thresholds, high-risk action oversight) place human authority exactly where neckbeard's five gates and stop rules sit; neither is more prescriptive. The readiness/release authority split exceeds both. | Anthropic; OpenAI | H | **ADOPT AS VALIDATED (no change)** | Independent convergence is evidence that the gate architecture is sound, not idiosyncratic. Preserve as-is; the divergence (more prescription) is justified by the doctrine's auditability goals and the packet ledger that makes verdicts inspectable. |
| **F8** | **Phase boundaries are correctly cut.** Design (3) vs specification (4) matches 15288/12207 architecture-vs-requirements separation and CMMI TS vs RD; QA-owned pre-implementation test planning (5) matches VER practice and the independence doctrine; review + boundary verification sharing phase 7 is acceptable because both bind verdicts to the same frozen head SHA and stages.md keeps the gate definitions separate; readiness-with-CI-loops (8) matches real PR mechanics. No merged-that-should-split or split-that-should-merge case survived analysis. Gate numbering (1→3→2→4→5 execution order) is explained in-text as area grouping; renumbering would break cross-references for zero evidentiary gain. | 15288; 12207; CMMI-DEV; Anthropic | H | **REJECT any restructuring** | Stability of the phase contract is itself a safety property; every framework examined supports the current cuts. |

## Part 3 — Explicit conclusion: does the nine-phase model have material gaps?

**The nine-phase journey has no material structural gaps.** Against four established lifecycle models, every phase of the change-delivery core (intake, discovery, design, specification, test planning, implementation, review, readiness, release) has a clear counterpart or a documented, defensible scope boundary. Against three published agentic-workflow approaches, the journey's gate placement and stop rules are not merely compatible but *converge independently* with vendor-published recommendations for human-oversight placement, and exceed them in auditability (SHA-bound verdicts, skip transparency, evidence ledger).

Three differences are material enough to act on, all **ADAPT**-class, all small:

1. **F1 — Record rollback/follow-up triggers at phase 9 closeout** so the terminal packet states what would cause re-entry (aligns journey with core-loop step 5; 15288 Operation/Maintenance, ITIL Deliver & Support).
2. **F2 — Add skip-transparent lesson capture to phase 9** (captured lesson + destination, or explicit "none identified") — this repairs an internal misalignment with stages.md Stage 6 and answers ITIL continual improvement / CMMI CAR at the smallest possible scale.
3. **F4 — Require explicit requester-outcome traceability in gate 3 acceptance criteria** (15288/12207/CMMI validation discipline).

One deliberate non-gap should be documented as such: **retirement/decommissioning (F3) is intentionally out of scope** and remains reachable as a high-risk change request under existing authority gates.

A well-evidenced near-null result, stated plainly: **nothing examined warrants adding, splitting, merging, or reordering phases.** If any change is pursued from this dossier, it should be limited to the three documentation-level adaptations above.

## Open questions / limitations

1. **Paywalled norms.** 15288, 12207, and ITIL 4 normative texts are license-encumbered; mappings rely on catalog metadata (Tier 1), a standards-summary corpus (arc42), and reputable secondary explainers cross-checked against each other. Clause-level citations (e.g., "6.4.12") come from the corroborated clause inventory, not purchased copies. Risk of drift is low for structural claims but nonzero for fine detail.
2. **ITIL Version 5** (announced January 2026) replaces the service value chain with a digital-product-and-service lifecycle. Finding F2 rests on continual improvement, which survives in outline, but revalidate after publication.
3. **CMMI version.** CMMI V3.0 (2023) supersedes V1.3; the analysis used V1.3 because its full SEI text is publicly reproducible. The process-area concepts relied upon (CAR, PPQA, VER/VAL separation, DAR) persist in V3.0 by name; a V3.0 spot-check is cheap follow-up.
4. **ISO/IEC/IEEE 29148** (requirements engineering) was scoped in but **not retained**: only unauthorized scanned copies were locatable, and none were used (see log). Findings that might otherwise cite it (F4, F5) rest on 15288/12207/CMMI equivalents instead.
5. **Single-journey scope assumption.** The dossier evaluates the journey as a per-change-request model, matching its stated purpose. Portfolio-level concerns (multi-change programs, 15288 organizational project-enabling processes) were treated as out of scope by design.
6. **Un-fetched official mirrors.** DTIC/Kilthub copies of CMMI-DEV and IEEE Xplore entries were located but not retrieved (see log); conclusions do not depend on them.

# Research Log: Nine-Phase Journey Validation Against SDLC and Agentic Frameworks

- **Provenance:** subject pinned to journey.md SHA `04a9b60b58244b5007e9279d53ed504362303320`; comparison basis and doctrine lens recorded in the brief header.
- **Extraction vs synthesis:** the brief carries verdicts and synthesis; this log carries source-level records and the search/decision trail.
- **Not preserved:** paywalled full texts were not reproduced (license); only structural claims drawn from accessible metadata/corroboration are preserved. OpenAI PDF conversion artifact lives in `/tmp/journey-research/` (ephemeral; content represented by the retained claims above).

## Pre-publication gateway check

Academic/comprehensive track: inclusion/exclusion criteria fixed before searching; triangulation applied (each standards finding rests on ≥2 independent sources or is flagged single-source in the brief); confidence labels (H/M) assigned per finding; limitations and open questions stated explicitly; no factual claim in the brief rests on a rejected source.

# Change Contract

> Fill this in at Framing (Stage 1). Keep it short. A contract that needs a page
> is hiding an ambiguity — surface it instead. One standing exception: any
> issue or ticket body this run emits must be self-contained for a cold reader
> (see the Issue/ticket body section). Litmus test: could someone who found the
> body via search act on it without asking anyone anything?

## Change-request provenance

<!-- Where this change comes from. Same fields and semantics as the delivery
     packet section (a) and the evidence ledger provenance section. -->

- **Change-request URL or number:** <!-- URL or tracker number -->
- **Source type:** <!-- issue / ticket / email / verbal -->
- **Repository:** <!-- repo path or URL -->
- **Base ref:** <!-- branch or ref the change is based on -->

## Problem
<!-- The user-visible problem in one or two sentences. What is wrong or missing
     from the user's point of view, not the implementation's. -->

## Authority
<!-- One of: explore / modify / publish / deploy / merge. If unclear, write
     "explore (assumed)" and flag that confirmation is needed. -->

## Constraints
<!-- Platform, compatibility, performance, policy, license. The hard limits. -->

## Affected system boundary
<!-- What system/component this touches and where its edges are. -->

## Risks
<!-- What could go wrong. Blast radius. What else depends on this area. -->

## Non-goals
<!-- What this change will explicitly NOT do. -->

## Acceptance criteria
<!-- Observable conditions that mean "satisfied." Each should be checkable at a
     named boundary (unit / integration / end-to-end / production).
     At least one criterion must trace back to the Problem section above —
     it proves the change solves the requester's actual problem, not just
     that the build matches the spec. -->

## Declared verification target
<!-- The boundary the contract actually cares about. This is what "done" must be
     proven against. -->

## Decision: change warranted?
<!-- yes / no. If no, stop here and record the evidence for "no change needed." -->

## Skip reason

<!-- If no change is warranted (decision above is "no"), record why. Same
     semantics as the delivery packet group (e) skip-reason fields: a concrete
     reason why an expected action was skipped; silent omission is prohibited. -->

## Issue/ticket body (cold-reader requirement)

<!-- Applies to any issue or ticket body emitted from this run — a new tracker
     item or a substantive comment on the source request. The reader has none of
     this session's context and no access to the agent's local artifacts. A
     body that fails any item below is not ready to file: rewrite it before
     submission. Litmus test: could someone who found this issue via search act
     on it without asking anyone anything? -->

- **Background section:** names the investigation — tools used with links,
  date, scope, and a sketch of the method.
- **Complete inline evidence:** the full affected list with `file:line`
  references in the target repository. No samples-plus-"on request": anything
  promised for later must instead be included now.
- **Reproduction commands:** runnable by a stranger on a fresh checkout.
- **Acceptance criteria** as checkable checkboxes.
- **No agent-local paths or private-artifact references** in the public body
  (scratch directories, local evidence ledgers, delivery packets). If evidence
  lives only outside the repository, inline it.

## Gate verdict

<!-- Framing-gate outcome for this contract. Same structure and semantics as the
     delivery packet section (h) gate-verdict fields. -->

- **Gate identifier:** <!-- e.g. framing-gate -->
- **Verdict:** <!-- pass / conditional / blocked -->
- **Evidence:** <!-- path or reference to supporting evidence -->
- **Head SHA:** <!-- SHA at which the verdict was reached -->

## PR / CI status

<!-- Placeholders for delivery tracking. Same semantics as the delivery packet
     section (i) lifecycle fields. -->

- **PR number:** <!-- PR or review-submission number, filled at submission -->
- **CI status:** <!-- passing / failing / pending / not-applicable -->

## Release status

<!-- Release disposition. Same semantics as the delivery packet section (i)
     release-status field. -->
<!-- not-released / release-ready / released / not-applicable -->

# Decision Record

> Write one when a choice is consequential or hard to reverse, or when you
> deliberately pick a simple design with a known ceiling. Lightweight — this is
> not a full ADR (use the `adr-authoring` skill for architecture-level decisions).

## Decision
<!-- What was chosen, in one sentence. -->

## Context
<!-- Why this came up. The constraint or fork that forced a choice. -->

## Alternatives considered
<!-- Each option and why it was not chosen. -->
- 

## Rationale
<!-- Why the chosen option fits the verified contract and non-negotiables. -->

## Deliberate ceiling (if any)
<!-- If a simpler design was chosen, the known limit it accepts. -->

## Upgrade trigger
<!-- The condition under which this decision should be revisited. -->

## Reversibility
<!-- Easy / hard / irreversible. What it would cost to undo. -->

# Delivery Packet

> Fill one packet per change-request run. Each section mirrors a field group from
> [../references/delivery-packet.md](../references/delivery-packet.md). Replace
> every `_[fill: ...]_` marker with your value. The packet is a coordination
> handoff — record pointers, summaries, and verdicts, not specialist content.

## (a) Change-request provenance

<!-- Written at intake (phase 1). Identify the change request this work responds to. -->

- **Change-request URL or number:** _[fill: URL or tracker number, e.g. `https://github.com/org/repo/issues/42` or `JIRA-123`]_
- **Source type:** _[fill: issue / ticket / email / verbal]_
- **Repository:** _[fill: repo path or URL, e.g. `https://github.com/org/repo`]_
- **Base ref:** _[fill: branch or ref the change is based on, e.g. `main`]_
- **Issue/comment snapshot:** _[fill: request text, comments, and linked work captured at intake — paste inline or link to a snapshot file]_
- **Tracking system:** _[fill: system identified per ../references/tracker-discovery.md, e.g. `Linear (requester-confirmed)` / `GitHub Issues (detected: issue URL in request)`]_
- **Head SHA at intake:** _[fill: `git rev-parse HEAD` at intake, e.g. `a1b2c3d`]_

## (b) Granted authority + workflow mode/path

<!-- Written at intake (phase 1). See [../references/risk-authority-gates.md](../references/risk-authority-gates.md) for authority classes. -->

- **Authority class:** _[fill: Explore / Modify / Publish / Deploy / Merge — if unclear, write "explore (assumed)" and flag that confirmation is needed]_
- **Workflow mode:** _[fill: GitHub reference mode / enterprise mode]_
- **Selected path:** _[fill: lightweight / full / refactor / high-risk]_

## (c) Resumable phase/gate state + current head SHA

<!-- Updated by every phase at its gate. On resume, read this section first.
     Do not re-execute phases whose gates are recorded as passed unless the
     head SHA has changed materially (see the changed-head procedure in
     ../references/delivery-packet.md). -->

- **Current phase:** _[fill: phase name, e.g. `phase-7-independent-review`]_
- **Current gate:** _[fill: gate name, e.g. `gate-4-independent-review`]_
- **Last passed gate verdict head SHA:** _[fill: exact SHA at which the last gate passed, e.g. `9f2c1ab`]_
- **Current lifecycle state:** _[fill: intake / planning / implementation / in-review / ready / merged / closed / blocked / released]_

**Example (populated after a context boundary):**

```text
Current phase:                     phase-7-independent-review
Current gate:                      gate-4-independent-review
Last passed gate verdict head SHA: 9f2c1ab
Current lifecycle state:           in-review
```

A resuming agent reads: phases 1–6 and gates 1, 3, 2 are recorded as passed in
section (h) and are not re-executed. Resume at phase 7, completing gate 4 then
gate 5. Compare the recorded SHA `9f2c1ab` to the actual head; if they differ,
run the changed-head procedure in
[../references/delivery-packet.md](../references/delivery-packet.md) before
continuing.

## (d) Problem / baseline evidence / scope / non-goals / affected surfaces

<!-- Phase 1 frames the problem, scope, non-goals, and affected surfaces;
     phase 2 (discovery and reproduction) completes the baseline evidence.
     Label every evidence entry as baseline or post-change and name the
     boundary exercised. -->

- **User-visible problem:** _[fill: one or two sentences — what is wrong or missing from the user's point of view]_
- **Baseline (pre-change) evidence:** _[fill: reproduction output, current-state observations — label boundary: component / integration / end-to-end / production; label stage: baseline]_
- **In-scope work:** _[fill: what this change will do]_
- **Non-goals:** _[fill: what this change will explicitly NOT do]_
- **Affected surfaces:** _[fill: paths, contracts, boundaries touched]_

## (e) Routing: selected skills + explicitly skipped skills with reasons

<!-- Phase 1 selects the path; each phase appends its routing decisions as it
     runs. Every skipped phase and every skipped skill must carry a concrete
     reason — silent omission is prohibited. See
     [../references/routing-table.md](../references/routing-table.md) for
     applicability signals and skip rules. -->

- **Selected skills:** _[fill: skill name + per-stage lead when several compose, e.g. "backend-engineering (lead: implementation), api-design-and-evolution (lead: contract design)"]_
- **Skipped phases with reasons:**
  - _[fill: e.g. "phase 3 (architecture delta): lightweight path, single-function bug fix, no architecture impact"]_
- **Skipped skills with reasons:**
  - _[fill: e.g. "frontend-engineering: change touches backend API only"]_
- **No-specialist fallback:** _[fill: "no specialist selected — no applicability signal triggered" when no routing row triggers; otherwise "N/A"]_

## (f) Design: architecture delta / decisions / risks / compatibility / migration / rollback

<!-- Written by phase 3. If there is no architecture impact, record a
     documented "no delta" determination rather than leaving this blank. -->

- **Architecture delta:** _[fill: path to `ARCHITECTURE-DELTA.md`, or "no delta — <reason>"]_
- **Decisions:** _[fill: key design decisions and their rationale]_
- **Rejected alternatives:** _[fill: approaches considered and why each was not chosen]_
- **Risks:** _[fill: what could go wrong; blast radius; what depends on this area]_
- **Compatibility:** _[fill: backward/forward compatibility analysis]_
- **Migration strategy:** _[fill: migration steps, or "none required"]_
- **Rollback plan:** _[fill: how to revert if this change fails]_

## (g) Plan: spec / acceptance criteria / test strategy / task plan / verification report paths

<!-- Written by phases 4–5. Link to specialist artifacts; do not duplicate
     their content here. -->

- **SPEC.md path:** _[fill: e.g. `SPEC.md`]_
- **Acceptance criteria mapping:** _[fill: AC identifiers mapped to change-contract acceptance criteria; identify which criterion traces to the requester's stated outcome (contract Problem section, restated in phase 2) — required for the gate-3 verdict]_
- **Test strategy:** _[fill: test levels (unit / integration / end-to-end), regression coverage strategy]_
- **TASK-PLAN.md path:** _[fill: e.g. `TASK-PLAN.md`]_
- **QA verification plan path:** _[fill: e.g. `VERIFICATION-PLAN.md`]_
- **Verification report paths:** _[fill: e.g. `VERIFICATION.md`, test output logs]_

## (h) Gates: verdicts / assumptions / rejected alternatives / unresolved boundaries / evidence pointers

<!-- Each gate's owning phase writes its verdict here. Every verdict MUST
     include the exact head SHA to which it applies. Gate numbers group by
     area; chronological execution order is gate 1 → gate 3 → gate 2 →
     gate 4 → gate 5. -->

| Gate | Verdict | Head SHA | Evidence | Conditions / blocker |
|------|---------|----------|----------|---------------------|
| gate-1 (architecture/design delta) | _[fill: pass / conditional / blocked]_ | _[fill: e.g. `a1b2c3d`]_ | _[fill: path to evidence artifact]_ | _[fill: unresolved conditions or blocker reason, or "none"]_ |
| gate-2 (QA test & verification plan) | _[fill: pass / conditional / blocked]_ | _[fill: SHA]_ | _[fill: path]_ | _[fill: or "none"]_ |
| gate-3 (spec + task-plan completeness) | _[fill: pass / conditional / blocked]_ | _[fill: SHA]_ | _[fill: path]_ | _[fill: or "none"]_ |
| gate-4 (independent review) | _[fill: pass / conditional / blocked]_ | _[fill: SHA]_ | _[fill: path]_ | _[fill: or "none"]_ |
| gate-5 (boundary verification) | _[fill: pass / conditional / blocked]_ | _[fill: SHA]_ | _[fill: path]_ | _[fill: or "none"]_ |

**Verdict semantics:** pass = phase may exit, next phase may start. conditional =
phase may exit only with recorded conditions tracked and closed before the next
gate. blocked = phase may not exit, run stops and escalates per
[../references/risk-authority-gates.md](../references/risk-authority-gates.md),
packet transitions to blocked.

**Example (populated gate verdict):**

```text
gate-1 (architecture/design delta) | pass | a1b2c3d | ARCHITECTURE-DELTA.md | none
```

- **Assumptions:** _[fill: unverified assumptions stated explicitly]_
- **Rejected alternatives:** _[fill: design or approach alternatives rejected during gate reviews]_
- **Unresolved boundaries:** _[fill: boundaries not yet verified, or "none"]_
- **Evidence pointers:** _[fill: repo-relative paths to evidence artifacts, updated throughout the run]_

## (i) Lifecycle: PR / CI / review / final verified head SHA / release status

<!-- Written by phases 8–9. The final verified head SHA MUST equal the actual
     final head of the delivered change. -->

- **PR (or review-submission) number:** _[fill: e.g. `#42` or enterprise review ID]_
- **CI status:** _[fill: passing / failing / pending / not-applicable]_
- **Review status:** _[fill: approved / changes-requested / pending / not-applicable]_
- **Final verified head SHA:** _[fill: exact SHA at which all verdicts were re-confirmed, e.g. `7b40de2`]_
- **Release status:** _[fill: not-released / release-ready / released / not-applicable]_
- **Terminal lifecycle state:** _[fill: merged / closed / blocked / released]_
- **Terminal state evidence:** _[fill: merge commit SHA, closure reason, or blocker reference]_
- **Rollback/follow-up triggers:** _[fill: conditions that would cause re-entry after closeout — e.g., a post-release regression requiring rollback or an operational discovery; write "none identified" if there are none. Recorded in the terminal record; any follow-up starts a new change request via phase 1 intake, never by re-opening this packet.]_
- **Lessons captured:** _[fill: reusable lesson(s) captured per Stage 6 "Deliver and learn" with their durable destination — skill, memory, or project docs — e.g., "multi-byte input handling lesson → project docs runbook"; or write "no reusable lesson identified". Recorded in the terminal record; silent omission is prohibited.]_

**Example (populated lifecycle):**

```text
PR (or review-submission) number: #42
CI status:                        passing
Review status:                    approved
Final verified head SHA:          7b40de2
Release status:                   release-ready
Terminal lifecycle state:         merged
Terminal state evidence:          merge commit 8c31ef4
Rollback/follow-up triggers:      post-release smoke check failure in the
                                  export path; operational discovery of
                                  multi-byte handling in adjacent endpoints
Lessons captured:                 multi-byte input boundary lesson →
                                  project docs runbook (export section)
```

### Blocked-state record

<!-- Complete this subsection ONLY if any gate verdict in section (h) is
     blocked. A blocked verdict transitions the packet to the blocked
     lifecycle state. Do not continue from a blocked packet without new
     authority or instructions. -->

- **Failing gate identifier:** _[fill: e.g. `gate-4-independent-review`]_
- **Phase at which it occurred:** _[fill: e.g. `phase-7-independent-review`]_
- **Blocking evidence:** _[fill: what was observed that failed the gate]_
- **Escalation outcome:** _[fill: decision or authority needed to proceed, per ../references/risk-authority-gates.md]_

## Shared field reference

The following field categories share identical names and semantics with
[change-contract.md](change-contract.md) and
[evidence-ledger.md](evidence-ledger.md):

- **Change-request provenance** — change-request URL or number; source type
  (issue / ticket / email / verbal); repository; base ref.
- **Skip reason** — a concrete reason why an expected action was skipped or
  deemed unnecessary; silent omission is prohibited.
- **Gate verdict** — gate identifier; verdict (pass / conditional / blocked);
  supporting evidence; head SHA at which the verdict was reached.
- **PR / CI status** — PR (or review-submission) number; CI status.
- **Release status** — release disposition: not-released / release-ready /
  released / not-applicable.

# Evaluation Report

> Every performance claim must be scoped to the evaluated models, harnesses,
> repositories, task classes, and dates below. No "10x," "always," or "best"
> without a published, reproducible definition and evidence. LOC is diagnostic
> metadata only — never a success proxy.

## Run identity
| Field | Value |
|---|---|
| Bundle revision | <!-- git SHA of neckbeard --> |
| Fixture revision | <!-- git SHA / tag of eval/fixtures --> |
| Date(s) |  |
| Rater(s) | <!-- two independent raters, or adjudication process, for high-stakes claims --> |

## Models and harnesses compared
| Arm | Model + version | Harness / system prompt | Tools available | Randomization | Run count |
|---|---|---|---|---|---|
| neckbeard |  |  |  |  |  |
| baseline (context-equivalent) |  |  |  |  |  |

## Task classes exercised
<!-- bug diagnosis, feature change, refactor, spec ambiguity, regression
     prevention, review finding, release verification, no-change-needed,
     adversarial. Note which were public vs. holdout. -->
- Public:
- Holdout:

## Outcome scores
<!-- Score per dimension from eval/rubric.md. Report variance / confidence
     intervals across runs — never a single point estimate as a universal claim. -->

## Adversarial / counterfactual behavior
<!-- Did the bundle correctly choose a larger change, a new dependency, a process
     change, or no code change where that was the right answer? -->

## Scoped claim
<!-- The only claim this run supports, bounded by model/harness/repo/task/date. -->

## Artifacts retained
<!-- Prompts, fixtures, rubric, commands, raw anonymized outputs (if licensing
     permits), aggregation script. Paths/links. -->

## Declared verification target
<!-- The boundary the change contract cares about: unit / integration /
     end-to-end / production. -->

## Checks, layered
<!-- From focused to broad. Map each check to the boundary it actually covers. -->
| Check | Command / method | Boundary it covers |
|---|---|---|
|  |  |  |

<!-- Trust-boundary validation, data safety, security, accessibility,
     observability, operational recovery, explicitly requested behavior. List the
     ones relevant here and how each is confirmed. -->
- 

## Rollback / recovery evidence
<!-- How the change is undone if it fails in the target environment. -->

## Gaps
<!-- Any declared-target boundary that cannot be exercised, and the weaker check
     that stands in for it (if any). -->
- 

## Verdict
<!-- pass / conditional / blocked — with the evidence. Use the
     verification-methodology skill's verdict format when available. -->
