Do NOT ask the user questions.\nRead the actual codebase, evaluate debt management algorithms, interest calculations,\npayment scheduling, credit score modeling, hardship workflows, and progress visualization,\nthen produce a comprehensive analysis.</p>\n<p>TARGET:\n$ARGUMENTS</p>\n<p>If arguments are provided, use them to focus the analysis (e.g., \"avalanche strategy\"\nor \"interest calculations\"). If no arguments, run the full analysis.</p>\n<h1>============================================================\nPHASE 1: SYSTEM DISCOVERY</h1>\n<p>Step 1.1 -- Technology Stack</p>\n<p>Scan package manifests and config files to identify: platform type (web app, mobile,\nAPI service, hybrid), backend framework, database engine, financial calculation libraries,\ncharting/visualization libraries, notification services, payment processing integrations,\ncredit bureau API connections, data export formats.</p>\n<p>Step 1.2 -- Debt Data Model</p>\n<p>Read core data structures and schemas for:</p>\n<ul>\n<li>Debts: principal balance, interest rate, minimum payment, payment due date, creditor\nname, account type (credit card, student loan, mortgage, auto loan, medical, personal loan)</li>\n<li>Payment records: date, amount, principal applied, interest applied, extra payment allocation</li>\n<li>User profiles: income, expenses, monthly budget surplus, credit score, financial goals</li>\n<li>Debt snapshots: point-in-time balances for historical tracking</li>\n</ul>\n<p>Step 1.3 -- External Integrations</p>\n<p>Map external data sources: bank account aggregation (Plaid, Yodlee, MX), credit bureau\nAPIs (Experian, TransUnion, Equifax), payment processors, loan servicer APIs, credit\nscore simulators, financial literacy content providers, budgeting tool integrations.</p>\n<h1>============================================================\nPHASE 2: PAYOFF STRATEGY ENGINE</h1>\n<p>Step 2.1 -- Avalanche Method</p>\n<p>Verify: correct ordering by interest rate (highest first), minimum payment allocation\nto all debts before extra payments, extra payment targeting to highest-rate debt,\nrollover of freed payments when a debt is eliminated, handling of variable-rate debts\n(rate recalculation triggers), proper treatment of promotional 0% APR periods (switch\ntargeting before promo expires), total interest saved calculation accuracy.</p>\n<p>Step 2.2 -- Snowball Method</p>\n<p>Verify: correct ordering by balance (smallest first), psychological milestone tracking\n(debt elimination celebrations), minimum payment allocation accuracy, rollover mechanics,\nhandling of debts with equal balances (tiebreaker logic), total interest cost comparison\nvs. avalanche, estimated payoff timeline calculation.</p>\n<p>Step 2.3 -- Hybrid and Custom Strategies</p>\n<p>Verify: hybrid options (e.g., snowball first two debts then avalanche), user-defined\npriority ordering, consolidation scenario modeling (new single loan replacing multiple\ndebts), balance transfer optimization (fee vs. interest savings), refinancing scenario\ncomparison, lump-sum windfall allocation, bi-weekly payment strategies, round-up\npayment integration.</p>\n<p>Step 2.4 -- Strategy Comparison Engine</p>\n<p>Verify: side-by-side comparison of all strategies for the same debt portfolio, metrics\ncompared (total interest paid, time to debt-free, number of debts eliminated per year,\nmonthly cash flow impact), sensitivity analysis (what if extra payment changes by\n+/- $100), break-even analysis for consolidation and balance transfers.</p>\n<h1>============================================================\nPHASE 3: INTEREST CALCULATION ACCURACY</h1>\n<p>Step 3.1 -- Interest Computation Methods</p>\n<p>Verify: daily vs. monthly accrual handling, average daily balance calculation, compound\ninterest frequency (daily, monthly, continuous), grace period handling (credit cards --\nno interest if paid in full), minimum interest charges, interest rate type handling\n(fixed, variable, introductory/promotional), APR to daily rate conversion accuracy\n(APR / 365 vs. APR / 360), amortization schedule generation.</p>\n<p>Step 3.2 -- Edge Cases</p>\n<p>Verify: leap year handling in daily interest (365 vs. 366 days), partial month interest\non new debts, interest on late fees and penalties, capitalized interest (unpaid interest\nadded to principal -- student loans), negative amortization detection, interest rate\nchange mid-billing-cycle, retroactive interest on expired promotional rates,\ncompound-on-compound accuracy over long horizons.</p>\n<p>Step 3.3 -- Amortization Accuracy</p>\n<p>Verify: amortization table generation for each debt type, remaining balance accuracy\nafter each payment, final payment adjustment (last payment often differs), extra payment\nimpact on amortization recalculation, total interest over life of loan, comparison with\nofficial servicer amortization tables when available.</p>\n<h1>============================================================\nPHASE 4: PAYMENT SCHEDULING AND AUTOMATION</h1>\n<p>Step 4.1 -- Payment Calendar</p>\n<p>Evaluate: due date tracking per debt, payment frequency options (monthly, bi-weekly,\nweekly), multi-debt payment coordination (stagger or batch), income-aligned scheduling\n(pay debts after payday), holiday and weekend adjustment logic, payment processing\nlead time accounting.</p>\n<p>Step 4.2 -- Automation Features</p>\n<p>Evaluate: automatic minimum payment scheduling, extra payment auto-allocation based\non selected strategy, payment amount adjustment when a debt is eliminated, notifications\nbefore payment processing, failed payment retry logic, insufficient funds handling,\npayment confirmation tracking.</p>\n<p>Step 4.3 -- Payment Flexibility</p>\n<p>Evaluate: skip-a-payment handling (recalculates timeline and interest cost), temporary\npayment reduction workflows, extra payment one-time vs. recurring, payment reallocation\nwhen priorities change, mid-cycle strategy switching (avalanche to snowball), pause\nand resume functionality.</p>\n<h1>============================================================\nPHASE 5: CREDIT SCORE IMPACT MODELING</h1>\n<p>Step 5.1 -- Credit Utilization Tracking</p>\n<p>Evaluate: credit utilization ratio calculation per card and aggregate, utilization\nprojection as balances decrease, optimal utilization targets (below 30%, below 10%),\nimpact of closing accounts after payoff on utilization, authorized user considerations.</p>\n<p>Step 5.2 -- Score Impact Projections</p>\n<p>Evaluate: credit score change estimates as debts are paid down, factors modeled\n(utilization, payment history, account age, credit mix, new inquiries), score\nprojection methodology (FICO simulation, VantageScore, or proprietary), projection\naccuracy validation, timeline to target score milestones, impact of debt-free status.</p>\n<p>Step 5.3 -- Score Model Transparency</p>\n<p>Evaluate: whether the model explains which factors drive score changes, confidence\nintervals on projections, disclaimers about model limitations, comparison with\nactual score (if credit monitoring integrated), handling of derogatory marks\n(collections, charge-offs, bankruptcies).</p>\n<h1>============================================================\nPHASE 6: HARDSHIP AND SPECIAL CIRCUMSTANCES</h1>\n<p>Step 6.1 -- Income Change Handling</p>\n<p>Evaluate: income reduction scenario modeling, job loss planning mode (minimum payments\nonly, prioritize essentials), income increase reallocation (automatically increase\nextra payments), irregular income handling (freelancers, seasonal workers), household\nincome vs. individual income support.</p>\n<p>Step 6.2 -- Hardship Accommodation Workflows</p>\n<p>Evaluate: deferment and forbearance modeling (paused payments, accruing interest),\nincome-driven repayment plan integration (student loans -- IBR, PAYE, REPAYE, SAVE),\nhardship program eligibility detection, creditor negotiation guidance (lower rate,\nwaive fees, settlement), debt management plan (DMP) comparison, bankruptcy impact\nmodeling (Chapter 7 vs. 13), statute of limitations awareness for old debts.</p>\n<p>Step 6.3 -- Emergency Fund Integration</p>\n<p>Evaluate: whether the system balances debt payoff vs. emergency savings, recommended\nemergency fund targets before aggressive debt payoff, unexpected expense impact on\ndebt timeline, emergency fund depletion recovery planning.</p>\n<h1>============================================================\nPHASE 7: PROGRESS VISUALIZATION AND MOTIVATION</h1>\n<p>Step 7.1 -- Dashboard and Charts</p>\n<p>Evaluate: total debt balance over time chart, individual debt payoff progress bars,\ninterest paid vs. principal paid breakdown, debt-free date countdown, milestone\nmarkers (each debt eliminated, percentage milestones), comparison to original\ntimeline (ahead or behind), monthly payment waterfall visualization.</p>\n<p>Step 7.2 -- Motivational Features</p>\n<p>Evaluate: debt elimination celebrations, streak tracking (consecutive on-time\npayments), total interest saved vs. minimum-payment-only scenario, net worth\nimpact tracking, community or social features (anonymized progress sharing),\ngamification elements (badges, levels, challenges).</p>\n<p>Step 7.3 -- Reporting and Export</p>\n<p>Evaluate: monthly progress reports, year-end tax-relevant summaries (mortgage\ninterest, student loan interest deduction), data export for financial advisors,\nprintable debt payoff plan, scenario comparison reports.</p>\n<p>Write analysis to <code>docs/debt-payoff-analysis.md</code> (create <code>docs/</code> if needed).</p>\n<h1>============================================================\nSELF-HEALING VALIDATION (max 2 iterations)</h1>\n<p>After producing output, validate data quality and completeness:</p>\n<ol>\n<li>Verify all output sections have substantive content (not just headers).</li>\n<li>Verify every
