Current Phase

P3: Performance, Observability & Developer Experience - Performance optimization, enhanced observability, developer experience improvements, and documentation polish

Status: ✅ Complete — Tagged as baseline: v1.0.11-p3-complete

What This Baseline Includes:

• ✅ P0: Publish safety & CI hardening (packaging, exports, CI debuggability)
• ✅ P1.4: Shared core types module (errors/enums/contracts/events/guards)
• ✅ P1.5: Documentation consolidation (authoritative index, drift guards, archive standardization, contracts as policy)
• ✅ P2.6: Type safety cleanup (zero any except documented TS mixin limitation)
• ✅ P2.7: System invariants documentation (SYSTEM_INVARIANTS.md created)
• ✅ P2.1: Schema versioning strategy (iOS explicit version tracking in CoreData metadata)
• ✅ P2.2: Combined edge case tests (3 resilience scenarios: DST + duplicate + cold start, rollover + duplicate + cold start, schema version + cold start)
• ✅ Core module purity enforcement (platform import blocking, export validation)
• ✅ Consumer migration complete (observability, definitions, web use core types)
• ✅ All invariants enforced in tooling (verify.sh + ci/run.sh)

---

Last Verify Run

Date: 2025-12-22
Result: ✅ Publish-safety checks pass on Linux (TypeScript + build + pack checks); Android/iOS native builds skipped (expected)
Local CI Command: ./ci/run.sh (wraps ./scripts/verify.sh)
Verification:

• ./scripts/verify.sh - All critical checks passed
• npm pack --dry-run | grep -E "xcuserdata|xcuserstate|DerivedData|ios/App/" - Empty (no forbidden files)

---

Blockers

None currently.

Packaging Invariants

Policy: Packaging is controlled primarily by package.json.files (whitelist). .npmignore is secondary.

Required Checks:

• npm pack --dry-run | grep -E "xcuserdata|xcuserstate|DerivedData|ios/App/" must remain empty
• CI must fail if forbidden files appear in package
• exports["./web"] paths must match actual build artifacts (dist/esm/web.{js,d.ts})

Verification: Run ./ci/run.sh (or make ci) before any publish - it includes forbidden files check.

Local CI Policy: ./ci/run.sh is the single source of truth for CI. All publishing/releasing must be gated by ./ci/run.sh. See ci/README.md for details.

Critical Invariant: Any CI or release gate MUST call ./ci/run.sh (not npm run build directly), because verify.sh encodes packaging and core-purity invariants that must be checked before publish.

Git Hook: Pre-push hook available at githooks/pre-push (setup: git config core.hooksPath githooks). Calls ./ci/run.sh.

Baseline Tag: v1.0.11-p3-complete — This tag represents P3 completion (performance optimization, enhanced observability, developer experience improvements, and documentation polish). Use as rollback anchor or reference point for future work.

Previous Baselines:

• v1.0.11-p2.3-p1.5b-complete — P2.x completion + test harness cleanup
• v1.0.11-p2.3-complete — P2.3 milestone (Android parity achieved)
• v1.0.11-p2-complete — P2.x milestone (schema versioning + iOS combined tests)
• v1.0.11-p0-p1.4-p1.5-p2.6-p2.7-complete — Foundation + type safety milestone
• v1.0.11-p0-p1.4-complete — Foundation milestone (P0 publish safety, P1.4 core module, P1.5 docs consolidation)

Type Safety Invariant: Only allowed any in repo: TS mixin constructor pattern (src/utils/PlatformServiceMixin.ts:258), documented inline. All external boundaries use unknown, all data payloads use Record<string, unknown>.
