# Progress Status

**Purpose:** Single source of truth for current project status, phase completion, blockers, and next actions.  
**Owner:** Development Team  
**Last Updated:** 2025-12-23  
**Status:** active  
**Baseline Tag:** `v1.0.11-p3-complete` (canonical baseline authority)

---

## 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)

## 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>`.
