/**
 * timmy-report — Generate Timmy's rubric report + reviewer context package.
 *
 * Collects git history data and key source file excerpts, then calls Claude
 * (via the Replit AI Integrations proxy) with the rubric dimensions as a
 * structured prompt. Writes two outputs:
 *
 *   reports/timmy-report.md   — Timmy's first-person evaluative perspective
 *   reports/context.md        — Self-contained package for Perplexity / Kimi Code
 *
 * Usage:
 *   pnpm --filter @workspace/scripts timmy-report
 *
 * Env vars (auto-provisioned by Replit):
 *   AI_INTEGRATIONS_ANTHROPIC_BASE_URL
 *   AI_INTEGRATIONS_ANTHROPIC_API_KEY

Commit Discipline: 5=atomic clear messages, 3=too large or vague, 1=giant mixed commits.
Reliability: 5=works, no regressions, 3=happy-path only, 1=introduces bugs.
Scope Adherence: 5=exactly what was asked, 3=mostly on target with drift, 1=wanders far.
Integration Awareness: 5=respects existing patterns, 3=clashes with conventions, 1=ignores codebase.

Composite = average. Grades: A=4.5–5.0, B=3.5–4.4, C=2.5–3.4, D=1.5–2.4, F=1.0–1.4.

Part 2: Orchestrator Grade (5 dimensions)
Task Clarity, Agent Selection, Review Cadence, Architecture Stewardship, Progress vs. Churn — each 1–5.

Part 3: Deliverables
1. Contributor summary (who touched what, commits, lines)
2. Per-contributor scorecards with composite grade and one-sentence verdict
3. Orchestrator scorecard
4. Top 3 improvements

## Key architectural facts for context

- Every external dependency has a **stub mode**: LNbits (in-memory invoices),
  Anthropic AI (canned responses), Digital Ocean (fake credentials + real SSH keypair).
- Env-var tunable constants follow a consistent pattern: \`envInt("VAR_NAME", defaultValue)\`.
- Service classes have a singleton export at the bottom of the file.
- All routes use \`makeLogger\` structured logger and \`@workspace/db\` Drizzle ORM.
- The \`eventBus\` pub/sub decouples state transitions from WebSocket broadcast.
- Job state machine: awaiting_eval_payment → evaluating → awaiting_work_payment → executing → complete/rejected/failed.
- Trust tiers: new → established (10pts) → trusted (50pts) → elite (200pts). Soft decay after 30 days absent.
- Pre-funded session mode (Mode 2): pay once, debit at actual cost, no per-job invoices.
- Testkit: 36 automated tests at GET /api/testkit (returns a self-contained bash script).
