Use when running tests/truth-cases/runner.test.ts, computing module-level pass rates, updating docs/phase0-validation-report.md and docs/failure-triage.md, or deciding between Phase 1A/1B/1C.'

Phoenix Truth-Case Orchestrator

You coordinate all truth-case work for the Phoenix VC fund model. The Phoenix Execution Plan defines 6 calculation modules and 119 truth-case scenarios; treat those JSON files plus the production code as the joint spec.

When to Use

Invoke this skill when:

• Running or modifying tests/truth-cases/runner.test.ts
• Updating module-level pass rates or Phase 0 / Phase 1A reports
• Classifying failures as CODE BUG / TRUTH CASE ERROR / MISSING FEATURE
• Making path decisions (Phase 1A vs 1B vs 1C) based on gate thresholds

Do not use this skill for:

• Fixing calculation precision (use phoenix-precision-guard)
• Changing core waterfall semantics (use phoenix-waterfall-ledger-semantics)

Files You Own

• Truth-case JSONs:
  • docs/xirr.truth-cases.json
  • docs/waterfall-tier.truth-cases.json
  • docs/waterfall-ledger.truth-cases.json
  • docs/fees.truth-cases.json
  • docs/capital-allocation.truth-cases.json
  • docs/exit-recycling.truth-cases.json
• Runner + helpers:
  • tests/truth-cases/runner.test.ts (build via /dev if missing)
  • tests/truth-cases/validation-helpers.ts (build via /dev if missing)
• Reports:
  • docs/phase0-validation-report.md
  • docs/failure-triage.md (create if missing)

Core Workflow

1. Run the Truth-Case Suite

Preferred:

Copy/test-smart truth-cases

Fallback:

Copynpm test -- tests/truth-cases/runner.test.ts --run --reporter=verbose

Capture:

• Per-module pass/fail counts
• Overall pass rate
• List of failing scenarios and error messages

2. Compute Module-Level Pass Rates

For each module:

• Count scenarios from the corresponding docs/*.truth-cases.json
• Count passing vs failing tests from the runner output
• Update the Module-Level Pass Rates table in docs/phase0-validation-report.md with:
  • X / Total (Y%)
  • PASS/FAIL relative to 1A/1B/1C thresholds
  • Recommended path per module

3. Classify Failures

For every failing scenario:

1. Read the error message
2. Inspect the production code implementing that module
3. Inspect the truth-case JSON

Classify each as:

• CODE BUG
• TRUTH CASE ERROR
• MISSING FEATURE

Record each scenario under the appropriate heading in docs/failure-triage.md.

4. Fix Truth-Case Errors First

If you determine a TRUTH CASE ERROR:

• Fix the JSON

• Re-run only that scenario:

  Copynpm test -- tests/truth-cases/runner.test.ts -t "<scenario-name>"
  

• Confirm it passes and doesn't break other scenarios

Only after JSON is correct should you propose code changes.

5. Apply Gate Logic for Phase Routing

Using the thresholds defined in the Phoenix Execution Plan, decide:

• Phase 1A (cleanup), 1B (bug fix), or 1C (rebuild)

Update docs/phase0-validation-report.md with:

• Module-level pass rates
• Overall test pass rate
• Chosen path (1A/1B/1C) and rationale

Numeric & Structural Semantics

When working in validation-helpers.ts or the runner:

• Use toBeCloseTo(expected, 6) for all numeric comparisons
• Ignore notes fields in expected JSON
• Treat null in expected gpClawback as "expect undefined in code"
• For min/max ranges (e.g., recycled_min/max), assert:
  • actual >= min
  • actual <= max
• Support both:
  • Aggregate totals
  • Row-level assertions (e.g., ledger rows)

Invariants

• Never reduce the overall truth-case pass rate without explanation
• Never change truth-case semantics silently: update both JSON and docs
• Always re-run the truth-case suite after modifying code or JSON
