delegate round 34: fix zig rowid slab cache invalidation (TASK-051, 052)

subtleGradient · subtleGradient · commit 3fc49dbef3eb · 2025-12-15T10:44:36.000-05:00
- TASK-051: Fixed schema cache invalidation in changes_vtab.zig
  Root cause: getSchemaVersion() returned stale cached value
  Fix: Call checkSchemaVersion() before cache validity check
  Result: 52/52 parity tests passing

- TASK-052: Browser test failures were port conflict (not code bug)
  Result: 18/18 browser tests passing

New backlog tasks created (blocked on Tom):
- TASK-053/054: Browser runtime specs (Phase 1/2)
- TASK-055/056: Tom decision tasks for scope/naming

+**Known gaps / unverified claims**
+- Zig parity tests have 4 failures (rowid slab for multi-table changes vtab)
+- Browser tests have 18 failures (not investigated this round)
+- `@effect-native/crsql` package tests fail due to `better-sqlite3` native binding missing — infrastructure issue, not code bug
+- No new task cards created — waiting for Tom direction on:
+  1. Whether to create tasks for Zig test failures
+  2. Whether to create Phase 2 browser runtime spec tasks
+  3. Scope for upstream feedback task
+
+**Next actions (require Tom input)**
+1. **Create Zig fix tasks** — rowid slab + browser test failures are non-TypeScript work
+2. **Create Phase 2 browser spec tasks** — would unblock TASK-031/032
+3. **Scope TASK-037** — define upstream feedback scope

+```
+</details>
+
+**Root cause analyses**
+
+1. **TASK-051 (Zig rowid slab)**: The `crsql_changes` virtual table's schema-version keyed cache was not being properly invalidated when new CRR tables were created. In `changesFilter()`, `getSchemaVersion()` returned the **cached** schema version without checking if SQLite's `PRAGMA schema_version` had changed. Fix: Added call to `cache.checkSchemaVersion()` before checking cache validity.
+
+2. **TASK-052 (Browser tests)**: All 18 failures were caused by **port conflict** (Python process on port 3456), not code bugs. The `serve` package silently picked a different port, while Playwright expected 3456. After freeing the port, all tests pass.
+
+**Reproduction steps (clean checkout)**
+1. `git clone <repo> && cd cr-sqlite`
+2. `make -C zig test-parity`
+3. Ensure port 3456 is free: `lsof -i :3456`
+4. `make -C zig test-browser`

+
+## Description
+Create Phase 1 spec instructions for the browser multi-tab runtime so that Phase 2 requirements can be written and TS implementation can become unblocked.
+
+This task produces only `instructions.md` (Phase 1) in a new spec directory under `effect-native/.specs/`.
+
+## Files to Modify
+- `effect-native/.specs/<new-browser-runtime-spec>/instructions.md`
+- `effect-native/.specs/README.md` (add cross-link, if applicable)
+- `research/zig-cr/92-gap-backlog.md` (link to spec)
+
+## Acceptance Criteria
+- [ ] New Phase 1 spec exists with:
+  - Context
+  - User Story
+  - High-Level Goals
+  - Out of Scope
+- [ ] The spec explicitly references the constraints from `research/zig-cr/96-proposal-multitab-wasm-sqlite-crsqlite.md`:
+  - SharedWorker preferred, Service Worker fallback
+  - No COOP/COEP requirement
+  - Provider-tab dedicated worker owns OPFS
+- [ ] The spec calls out the minimal “notification/subscription” goal (db_version advanced events) needed by `.tasks/backlog/TASK-032-web-reactive-subscriptions.md`.
+
+## Progress Log
