Do NOT ask the user questions.\nRead the codebase, analyze shelf life models, inventory management, demand forecasting,\nand donation workflows, then produce a comprehensive food waste assessment.</p>\n<p>TARGET:\n$ARGUMENTS</p>\n<p>If arguments are provided, focus on specific areas (e.g., \"shelf life models\",\n\"inventory rotation\", \"donation logistics\"). If no arguments, run the full analysis.</p>\n<h1>============================================================\nPHASE 1: SYSTEM DISCOVERY</h1>\n<p>Step 1.1 -- Read project configuration to identify tech stack: backend, database\n(relational, time-series, IoT-optimized), ML/forecasting libraries, IoT sensor\npipelines, barcode/RFID integration, ERP integration, mobile tools, reporting.</p>\n<p>Step 1.2 -- Scan for supply chain stages covered: farm/producer, processing,\ndistribution/warehousing, retail, consumer, food recovery, composting/waste\nprocessing. Record data models, waste tracking, decision support for each.</p>\n<p>Step 1.3 -- Identify food categories: fresh produce, dairy, meat/poultry, seafood,\nbakery/deli, frozen, shelf-stable, prepared foods, beverages. Record category-specific\nhandling rules, shelf life parameters, storage requirements.</p>\n<h1>============================================================\nPHASE 2: SHELF LIFE PREDICTION</h1>\n<p>Step 2.1 -- Inventory shelf life models: static (fixed days), dynamic (temperature-\ntime integrated), ML-based quality degradation, Arrhenius kinetic, microbial\ngrowth, sensory quality. Record inputs, outputs, calibration data, accuracy.</p>\n<p>Step 2.2 -- Assess date management: label types (use-by, best-by, sell-by, pack\ndate), standardization, dynamic adjustment based on storage conditions, regulatory\ncompliance, lot tracking, recall capability.</p>\n<p>Step 2.3 -- Evaluate quality monitoring: temperature logging, quality inspection\nrecording, photo-based assessment, automated grading, quality trending, deviation\nalerts, regrading workflow.</p>\n<h1>============================================================\nPHASE 3: INVENTORY ROTATION</h1>\n<p>Step 3.1 -- Evaluate rotation strategy: FIFO enforcement, FEFO enforcement, LSFO\nimplementation, strategy by product category, system enforcement vs. recommendation,\npick path optimization, receiving/put-away logic.</p>\n<p>Step 3.2 -- Assess inventory visibility: lot-level tracking, pallet/case/item\ngranularity, real-time accuracy, aging reports, days-of-supply, stock-out vs.\noverstock balancing, multi-location visibility.</p>\n<p>Step 3.3 -- Check approaching-expiry management: days-before-expiry markdown\ntriggers, automated vs. manual markdown, pricing optimization, clearance sections,\nlocation transfers, donation trigger points.</p>\n<p>Step 3.4 -- Evaluate waste tracking: reason codes (expired, damaged, quality,\noverstock), tracking by category/supplier/location, shrink measurement, cost\nquantification, benchmarking, root cause analysis.</p>\n<h1>============================================================\nPHASE 4: DEMAND FORECASTING</h1>\n<p>Step 4.1 -- Assess forecasting models: time-series (ARIMA, Prophet), ML (gradient\nboosting, neural nets), causal (price, promotion, weather), collaborative\nforecasting. Check granularity, horizon, input features, accuracy metrics (MAPE).</p>\n<p>Step 4.2 -- Check forecast-to-order: automatic replenishment, safety stock\nmethodology, minimum order quantities, lead time handling, promotional uplift,\nseasonal adjustment, capacity constraints.</p>\n<p>Step 4.3 -- Evaluate forecast error impact: over-forecast to waste relationship,\nbias detection (systematic over/under-ordering), accuracy by perishability tier,\nby day of week, corrective feedback loop.</p>\n<p>Step 4.4 -- Check event handling: promotional uplift accuracy, holiday patterns,\nweather impact, local events, post-promotion dip modeling, cannibalization effects.</p>\n<h1>============================================================\nPHASE 5: DONATION AND COLD CHAIN</h1>\n<p>Step 5.1 -- Evaluate donation eligibility: product rules (past best-by but safe),\nquality standards, Good Samaritan Act protections, allergen transparency,\ntemperature requirements, packaging integrity.</p>\n<p>Step 5.2 -- Check distribution: food bank network database, recipient matching,\ngeographic routing optimization, scheduling, dietary preference management, fair\ndistribution, standing order support.</p>\n<p>Step 5.3 -- Evaluate donation operations: creation workflow, weight/value\nestimation for tax docs, transportation logistics, chain of custody, tax deduction\ncalculation, liability documentation, receipt generation.</p>\n<p>Step 5.4 -- Assess donation analytics: pounds by category, meals equivalent,\ncarbon avoided, cost of goods donated vs. disposal saved, trends, food safety\nincident tracking.</p>\n<p>Step 5.5 -- Evaluate temperature monitoring: sensor types, monitoring points,\ningestion frequency, alert thresholds, excursion detection, remaining shelf life\nrecalculation after break, transport monitoring.</p>\n<p>Step 5.6 -- Check cold chain compliance: FSMA compliance, HACCP integration,\ntemperature requirements by category, sanitary transport rule, record keeping,\naudit readiness.</p>\n<h1>============================================================\nPHASE 6: SUSTAINABILITY REPORTING</h1>\n<p>Step 6.1 -- Evaluate waste measurement: units (weight, dollars, calories),\nmeasurement points, waste per revenue, composition analysis, avoidable vs.\nunavoidable distinction, food waste hierarchy adherence.</p>\n<p>Step 6.2 -- Assess environmental impact: GHG emissions from waste (CO2e), water\nfootprint, land use impact, packaging waste, methane from landfill, carbon\nreduction from prevention.</p>\n<p>Step 6.3 -- Check reporting frameworks: GHG Protocol Scope 3, CDP, GRI, UN SDG\n12.3 tracking, EPA Food Recovery Hierarchy, SBTi alignment, ESG requirements.</p>\n<p>Step 6.4 -- Evaluate targets: baseline measurement, reduction targets (%, absolute),\nprogress tracking, trend visualization, industry benchmarking, ROI calculation.</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 finding references a specific file, code location, or data point.</li>\n<li>Verify recommendations are actionable and evidence-based.</li>\n<li>If the analysis consumed insufficient data (empty directories, missing configs),\nnote data gaps and attempt alternative discovery methods.</li>\n</ol>\n<p>IF VALIDATION FAILS:</p>\n<ul>\n<li>Identify which sections are incomplete or lack evidence</li>\n<li>Re-analyze the deficient areas with expanded search patterns</li>\n<li>Repeat up to 2 iterations</li>\n</ul>\n<p>IF STILL INCOMPLETE after 2 iterations:</p>\n<ul>\n<li>Flag specific gaps in the output</li>\n<li>Note what data would be needed to
