YellowJacket — Consolidation Milestone State

Project Reference

Core value: The music player works reliably and feels solid — every interaction is correct, responsive, and trustworthy. Current focus: Phase 2 complete — all backend correctness requirements delivered. Milestone: Consolidation (correctness, performance, code quality, UX polish, test coverage)

Current Position

Phase: 02-backend-correctness (complete) Plan: 2/2 (complete) Status: Milestone complete

Phase Progress: [##......] 2/8 phases complete

Accumulated Context

Key Decisions

Decision	Rationale	Phase
Fix races before tests	Can't run -race-clean tests with active data races	Phase 1 → 3
PRAGMAs with test infra	NewTestDB must mirror production DB setup; PRAGMAs change production NewDB	Phase 3
Tests before refactoring	Research unanimously recommends characterization tests as safety net	Phase 4-5 → 6-7
SQL consolidation after DB tests	FTS5 search tests verify VIEW doesn't change ranking	Phase 5 → 6
Frontend last	Backend API should be stable before frontend adapts	Phase 8
Release mutex before Wails runtime calls	Library/Playlist SetContext releases lock before registerEventHandlers/migrateExistingPlaylists to avoid blocking	Phase 1
Player SetContext single-lock	Collapsed double-lock to prevent partially-initialized observable state	Phase 1
MPRIS closures inline, Warn level	Non-fatal OS media control failures logged at Warn, kept as inline closures	Phase 2
Pass metrics through cachedLinkArtist	Consistent void-return pattern; warnings collected via addWarning	Phase 2
Fatal vs warning error classification	tx.Commit failures are fatal; all other scan errors are warnings in ScanMetrics	Phase 2

TODOs

• Plan Phase 1 (complete)
• Execute Phase 1 Plan 01 (complete)
• Plan Phase 2 (complete)
• Execute Phase 2 Plan 01 (complete)
• Execute Phase 2 Plan 02 (complete)
• Validate sqlc + SQLite VIEW + FTS5 compatibility during Phase 6 planning (research flag)
• Design queue test architecture during Phase 4 planning (research flag)
• Determine library scan test fixture strategy during Phase 5 planning (research flag)
• Measure startup time with large library before Phase 7 lazy loading work

Blockers

None currently.

Warnings

• Player lock ordering (p.mu before speaker.Lock(), goroutine dispatch in beep callback) — do NOT refactor lock-sensitive paths; extract pure logic only
• modernc.org/libc version must match exactly when updating modernc.org/sqlite
• @lit-labs/signals is experimental (v0.2.0) — not blocking but noted

Session Continuity

Last Session

Date: 2026-03-03 What happened: Executed Phase 2 Plan 02 — artist credit error checking & scan warning separation Where we stopped: Completed 02-02-PLAN.md (all 2 tasks, verification passed) Next action: /gsd-plan-phase 3 to create execution plan for Test Infrastructure

Context for Next Session

• Phase 2 complete: all 5 correctness requirements (CORR-05 through CORR-09) delivered
• database.IsUniqueViolation helper available for other upsert patterns
• ScanMetrics.Warnings collects non-fatal scan issues; Scan() error return is fatal-only
• Migration 3 added UNIQUE index on artist_credit_artist(artist_id, credit_id)
• codegen-check lefthook pre-commit hook hangs — use LEFTHOOK=0 for commits
• Ready for Phase 3 (Test Infrastructure)
