All tasks complete. Summary:

Modified file: src/metacognition/proposal-engine.ts (+103 lines)

Changes:

1. Added import { loadDailyMetrics, type DailyMetricsSummary } from metrics-collector
2. Added 'work-patterns' to ProposalSource union type
3. New analyzeWorkPatterns() function (~80 lines) that:
   • Loads 7 days of metrics via loadDailyMetrics() (SQLite API, not file reads)
   • Computes ELU P50 linear regression slope — alerts if >2%/day upward trend
   • Detects consecutive high-load days (P95 > 50% for 3+ days)
   • Tracks active/resting ratio imbalance (>85% active with >10% increase)
   • Returns 0-3 proposals with appropriate severity and scoring
4. Wired into generateProposals() as step 5

Compilation: tsc --noEmit passes cleanly
