Phase Ledger
The phase ledger tracks what was built, what was validated, what failed, what must carry forward, and what should be rechecked.
Summary
Section titled “Summary”Phase records should be updated at major transitions, not after every small commit.
Why This Matters
Section titled “Why This Matters”Phase transitions are where history is most often lost. This ledger keeps the current phase grounded in prior evidence.
Evidence Sources
Section titled “Evidence Sources”docs/STATE_SYNC.md- Generated task and timeline docs
- Review history
- Harness carryover docs
What Happened
Section titled “What Happened”Phase 1 produced the initial product foundation, analysis and lyric pipeline, music provider layer, orchestration layer, synchronous music route proof, board automation, and history architecture.
Decision / Lesson / Pattern
Section titled “Decision / Lesson / Pattern”Each phase should leave a concise retrospective before the next phase becomes active.
What To Preserve
Section titled “What To Preserve”| Phase | Built | Validated | Failed or Risky | Carry Forward | Recheck |
|---|---|---|---|---|---|
| Phase 1 | MVP foundation, music route proof, board sync | Tests, reviews, build, source clean checks | Timeout risk, PII boundary, context loss, source safety risk | Provider isolation, queue planning, board memory | Async architecture, launch gates |
| Phase 2 | Planned production hardening | To be validated | Queue and recovery unknowns | History-first workflow | Payment readiness |
| Phase 3 | Future launch/scale layer | To be validated | Unknown | Accepted harness rules | Product and policy fit |
| Future SaaS | Reusable board pattern | To be validated per project | Copying without adaptation | Repo separation and history templates | Domain-specific risks |
What To Recheck
Section titled “What To Recheck”- Phase 2 should recheck queue, retry, polling, and recovery behavior.
- Phase 3 should recheck launch risk, payment boundaries, and operational support.
- Future SaaS projects should recheck whether ForYouTune assumptions still apply.
Carry Forward
Section titled “Carry Forward”Promote phase records into next-generation carryover when they are broadly reusable.
