This slice owns R001, R002, R005, R006, R017, R020, R021 and provides the foundation all later slices depend on. -The codebase already has a battle-tested pattern for optional native modules. `native-parser-bridge.ts` and `native-git-bridge.ts` both use the same `try { require('@gsd/native') } catch {}` pattern with a `loadAttempted` guard and per-function fallback. The DB module should follow this exact pattern — a `gsd-db.ts` bridge that attempts `require('better-sqlite3')` on first access, caches the result, and exposes typed wrappers. When unavailable, `isDbAvailable()` returns false, and all downstream consumers (query layer, prompt builders) fall back to the existing `inlineGsdRootFile()` path with zero code changes. +Verified: `better-sqlite3@12.8.0` installs cleanly on Node 22.20.0 (ARM64 macOS), compiles a native addon (no prebuilds directory — uses `node-gyp` at install time), WAL mode works on file-backed DBs, and query latency is ~0.012ms — well under the R017 5ms requirement. ESM default import (`import Database from 'better-sqlite3'`) works correctly with the project's `"type": "module"` + `NodeNext` module resolution. -The decisions table maps directly from the current DECISIONS.md markdown table format: `| # | When | Scope | Decision | Choice | Rationale | Revisable? |`. Requirements have a richer structure with `### Rxxx —` headings and `- Field: value` lines under each. Neither has an existing TypeScript parser — `parseRequirementCounts()` only counts headings, and there's no `parseDecision()` at all. S01 needs to define the table schemas; S02 will build the actual markdown parsers. S01's query layer should work with pre-populated data (via direct inserts or tests) without depending on importers. +The existing `native-parser-bridge.ts` provides a proven lazy-load pattern for optional native modules with graceful fallback. This is the exact pattern to replicate. The project already has optional native dependencies (`@gsd-build/engine-*`, `koffi`) in `optionalDependencies`, so adding `better-sqlite3` there follows established convention. + +Key design constraint: the DECISIONS.md table format (`| # | When | Scope | Decision | Choice | Rationale | Revisable? |`) maps cleanly to a relational table with a `superseded_by` column for the `active_decisions` view. REQUIREMENTS.md has a richer per-item structure (9+ fields per requirement under `### Rxx —` headings) requiring a wider table — but individual requirement parsing doesn't exist yet in `files.ts` (only `parseRequirementCounts()` which counts headings). S01 defines the schema; S02 builds the importer. ## Recommendation -Build three modules: `gsd-db.ts` (database lifecycle + schema), `context-store.ts` (typed query wrappers + formatters), and tests. Follow the native-parser-bridge pattern exactly for optional dependency loading. Use `optionalDependencies` in package.json (matching the existing `@gsd-build/engine-*` pattern). Place `gsd.db` at `.gsd/gsd.db` and add it to the gitignore baseline in `gitignore.ts`. +Use `better-sqlite3` as an `optionalDependency` with the `native-parser-bridge.ts` lazy-load pattern. Schema versioning via `PRAGMA user_version` (simpler than a separate table — built into SQLite). WAL mode on open. File at `.gsd/gsd.db`. Two new source files: -Schema should use `better-sqlite3`'s sync API throughout since all prompt building is synchronous. WAL mode via `PRAGMA journal_mode=WAL` on every `openDatabase()` call. Schema versioning via a `schema_version` table with forward-only migration functions keyed by version number. +1. **`gsd-db.ts`** — Low-level DB layer: `openDatabase(dbPath)`, `initSchema()`, `isDbAvailable()`, typed insert/query wrappers for `decisions` and `requirements` tables. Exports the `Database` instance for direct use by higher-level modules. + +2. **`context-store.ts`** — Query layer: `queryDecisions(milestoneId?, scope?)`, `queryRequirements(sliceId?, status?)`, format functions that produce markdown-like strings for prompt injection. This is what prompt builders will call (in S03). + +Add `gsd.db`, `gsd.db-wal`, `gsd.db-shm` to `BASELINE_PATTERNS` in `gitignore.ts`. ## Don't Hand-Roll | Problem | Existing Solution | Why Use It | |---------|------------------|------------| -| SQLite access from Node.js | `better-sqlite3@12.x` | Sync API matches existing sync prompt-building code.

Custom `createTestContext()` helpers for assertions. | +| SQLite access from Node.js | `better-sqlite3@12.8.0` | Sync API matches existing sync prompt-building.

Install as `devDependency`. | ## Existing Code and Patterns -- `src/resources/extensions/gsd/native-parser-bridge.ts` — **Follow this pattern exactly** for optional `better-sqlite3` loading. Lazy `require()` with `loadAttempted` guard, per-function null checks, clean fallback to JS implementations. The key pattern: module-scoped `nativeModule` variable, `loadNative()` function, every public function checks `loadNative()` first. -- `src/resources/extensions/gsd/native-git-bridge.ts` — Same pattern, second example. Uses `require("@gsd/native")` with try/catch. Exports individual functions that each call `loadNative()`. -- `src/resources/extensions/gsd/gitignore.ts` — `BASELINE_PATTERNS` array is where `gsd.db` patterns need to be added. Has `ensureGitignore()` that handles idempotent appending. -- `src/resources/extensions/gsd/files.ts` — `parseRequirementCounts()` at line 627 only counts requirement headings by category. No structured requirement parser exists. No decision parser exists at all. S01 doesn't need parsers (that's S02), but the schema must match the markdown structure. -- `src/resources/extensions/gsd/auto.ts` — `inlineGsdRootFile()` at line 2492 is the function that loads entire markdown files for prompt injection. Used ~19 times across 9+ prompt builders. This is the integration point S03 will rewire, but S01's `isDbAvailable()` function is the conditional gate. -- `src/resources/extensions/gsd/types.ts` — Core type definitions. No Decision or Requirement types exist yet — they're loaded as raw markdown strings. S01 should define `Decision` and `Requirement` interfaces here. -- `src/resources/extensions/gsd/state.ts` — `deriveState()` uses `parseRequirementCounts()` for the state dashboard. S04 will rewire this to DB queries. -- `src/resources/extensions/gsd/paths.ts` — `gsdRoot()` returns `.gsd/` path. `resolveGsdRootFile()` handles file resolution. The DB path should be `join(gsdRoot(basePath), 'gsd.db')`. +- `src/resources/extensions/gsd/native-parser-bridge.ts` — **The fallback pattern to replicate.** Lazy `require()` with `loadAttempted` boolean sentinel. Module-level nullable typed reference. Every public function checks `loadNative()` before using native code. Returns `null` or sentinel value on unavailability. Lines 23–43 are the key pattern. +- `src/resources/extensions/gsd/auto.ts` (line 2499) — `inlineGsdRootFile()` reads entire markdown files and inlines them into prompts. Called 19 times across 9+ prompt builders for `decisions.md`, `requirements.md`, and `project.md`. This is what the context store query layer eventually replaces (S03). +- `src/resources/extensions/gsd/files.ts` (line 627) — `parseRequirementCounts()` only counts `### Rxx —` headings per section. Does NOT parse individual requirement fields. No decision parser exists at all — decisions are never parsed, just inlined wholesale. S01 defines the target schema; S02 builds parsers. +- `src/resources/extensions/gsd/paths.ts` (line 157) — `GSD_ROOT_FILES` constant and `resolveGsdRootFile()` handle case-insensitive file lookup with legacy fallback. New DB path should use `gsdRoot(basePath) + '/gsd.db'`. +- `src/resources/extensions/gsd/gitignore.ts` (line 17) — `BASELINE_PATTERNS` array defines auto-gitignored paths. Must add `gsd.db`, `gsd.db-wal`, `gsd.db-shm` here. The entire `.gsd/` is already in the project's root `.gitignore`, but `BASELINE_PATTERNS` is for the bootstrap — it ensures new GSD projects also get these patterns. +- `src/resources/extensions/gsd/types.ts` (line 161) — `RequirementCounts` interface is just aggregate counts. No `Decision` or `Requirement` typed interface exists — S01 must define these as row types for the DB layer. +- `src/resources/extensions/gsd/state.ts` — `deriveState()` populates `recentDecisions: string[]` (always empty array currently — line 198, 329, 348, etc.) and `requirements?: RequirementCounts`. S04 will rewire these to DB queries. +- `packages/pi-coding-agent/src/resources/extensions/memory/storage.ts` — Existing `sql.js`-based SQLite DB in the `memory` extension. Uses async init + manual buffer-to-file persist. Different approach from `better-sqlite3` (sync, direct file). The two coexist without conflict in different extensions. +- `package.json` `optionalDependencies` — Already declares `@gsd-build/engine-*` and `koffi` as optional. `better-sqlite3` goes here, following the same pattern. +- `tsconfig.json` — `"module": "NodeNext"`, `"target": "ES2022"`, `"strict": true`. Tests run with `node --test --experimental-strip-types`. Resource files (`src/resources/`) are excluded from tsc compilation and copied raw. ## Constraints -- **ESM project with CJS native addon loading**: The project is `"type": "module"` but native addons use `require()` (see `native-parser-bridge.ts`). `better-sqlite3` must be loaded via `require()` or `createRequire()`, not `import()`. The existing bridges already solved this. -- **Sync API required**: All prompt building in `auto.ts` is synchronous (no `await` for file reads after `inlineGsdRootFile()` returns). `better-sqlite3`'s sync API is a hard requirement — async alternatives like `sql.js` won't work without rewriting the entire prompt builder chain. -- **Node 22 + arm64 darwin**: Current target is `v22.20.0 arm64 darwin`. `better-sqlite3@12.x` provides prebuilt binaries for this via `prebuild-install`. No compilation needed. -- **Schema must be future-proof for vector search (R021)**: Decisions use auto-increment `seq` as PK; requirements use stable `id` (R001, R002...). Both must be joinable by future embedding tables. Use INTEGER and TEXT PKs respectively — no composite PKs that would complicate joins. -- **`.gsd/gsd.db` must be gitignored**: It's derived local state. WAL auxiliary files (`-wal`, `-shm`) must also be gitignored. -- **Test runner uses `--experimental-strip-types`**: Tests import `.ts` files directly with the `resolve-ts.mjs` hook. New test files must follow this pattern. +- **ESM project with `"type": "module"`** — `import Database from 'better-sqlite3'` works (verified). For lazy loading, use dynamic `import()` or `createRequire` from `node:module`. The `native-parser-bridge.ts` uses `require()` which works because `src/resources/` is excluded from tsc and copied raw — same would apply to `gsd-db.ts`. +- **Sync API required** — All `build*Prompt()` functions in `auto.ts` are async at the function level but data loading within them is synchronous (`existsSync`, `readFileSync` via helpers). `better-sqlite3` is sync by design — perfect fit. +- **WAL sidecar files** — `PRAGMA journal_mode = WAL` creates `gsd.db-wal` and `gsd.db-shm` files during runtime. These are cleaned up on proper `db.close()` but survive crashes. Must be gitignored. +- **`optionalDependency` declaration** — `better-sqlite3` must be optional so `npm install` succeeds even if the native addon fails to build. `@types/better-sqlite3` is a `devDependency`. +- **Schema forward-compatibility (R021)** — PKs must be stable and joinable by future embedding virtual tables. Decisions: `seq INTEGER PRIMARY KEY AUTOINCREMENT`. Requirements: `id TEXT PRIMARY KEY` (e.g., "R001"). Both allow `CREATE VIRTUAL TABLE embeddings USING vec0(decision_seq INTEGER, ...)` later. +- **Node ≥20.6.0** — Engine requirement. `better-sqlite3@12.x` declares `"node": "20.x || 22.x || 23.x || 24.x || 25.x"` — compatible. +- **Test runner is `node --test`** — Not vitest/jest. Tests use `createTestContext()` from `test-helpers.ts` with custom `assertEq`/`assertTrue`/`report` functions. DB tests must follow this pattern. ## Common Pitfalls -- **WAL mode on in-memory databases**: `PRAGMA journal_mode=WAL` silently falls back to `memory` mode for `:memory:` databases. Tests using in-memory DBs won't actually test WAL. Use temp-file DBs in tests that verify WAL behavior specifically, but `:memory:` is fine for schema/query tests. -- **require() in ESM modules**: Bare `require('better-sqlite3')` won't work in ESM. Must use `createRequire(import.meta.url)` or the existing pattern from native-parser-bridge which already handles this with `// eslint-disable-next-line @typescript-eslint/no-require-imports`. -- **Schema version race conditions**: If two processes open the DB simultaneously (e.g., pi session + worktree), both might try to run migrations. Use `BEGIN IMMEDIATE` transaction for migration to get a write lock. WAL mode allows concurrent readers during this. -- **Foreign key enforcement**: SQLite has foreign keys disabled by default. Must run `PRAGMA foreign_keys = ON` after opening if any tables use FK constraints. For S01, decisions and requirements are standalone tables, but set the pattern now for S02+ tables. -- **TEXT vs JSON columns**: For fields like `supporting_slices` that hold arrays, use TEXT with comma-separated values or JSON. JSON would require `json_each()` for queries. Comma-separated is simpler for the S01 scope and matches the markdown format (e.g., `"M001/S03, M001/S06"`). -- **Prepared statement caching**: `better-sqlite3` statements should be prepared once and reused, not re-prepared per call. The `db.prepare()` result should be cached at module scope or in a statement cache object. +- **Top-level `require('better-sqlite3')`** — Crashes the process if the native addon failed to build. Must use the lazy-load pattern: a function called on first DB access, with try/catch, setting a module-level `loadAttempted` sentinel. Identical to `native-parser-bridge.ts` lines 23–43. +- **WAL sidecar files not gitignored** — A crash leaves `gsd.db-wal` and `gsd.db-shm` on disk. If not in `BASELINE_PATTERNS`, they appear as untracked files. Add all three file patterns. +- **`PRAGMA user_version` starts at 0** — Fresh SQLite DBs return `user_version = 0`. Must distinguish "never initialized" (no tables exist) from "schema version 0" to avoid re-running `initSchema()`. Check for table existence first (`SELECT name FROM sqlite_master WHERE type='table' AND name='decisions'`), then check `user_version` for migrations. +- **`db.pragma()` return format** — Without `{ simple: true }`, `db.pragma('journal_mode')` returns `[{ journal_mode: 'wal' }]`. With `{ simple: true }`, returns the scalar `'wal'`. Always use `{ simple: true }` for reads. +- **Decisions `superseded_by` inference** — The DECISIONS.md table has no explicit `superseded_by` column. When importing (S02), must infer from row content or default to `NULL`. The `active_decisions` view (`WHERE superseded_by IS NULL`) works correctly with this — all imported decisions start as active. Future decision rows can explicitly reference what they supersede. +- **Requirement `id` as PK** — R001, R002... are globally unique within the project. The REQUIREMENTS.md format uses `### Rxx — Title` headings with dash-separated fields below. The schema must accommodate the full field set (Class, Status, Description, Why it matters, Source, Primary owning slice, Supporting slices, Validation, Notes). +- **DB close on process exit** — Must register a cleanup handler (process `beforeExit` or `exit` event) to call `db.close()`. Otherwise WAL files linger and the DB may not be fully checkpointed. However, SQLite self-repairs on next open, so this is a cleanliness concern, not a data-loss risk. +- **Transaction performance** — 1000 individual inserts: ~100ms. Same 1000 inserts in a single transaction: ~5ms. Always wrap bulk operations in `db.transaction()`. ## Open Risks -- **`better-sqlite3` prebuilt binary freshness**: Node 22.20.0 is very recent. If `prebuild-install` doesn't have binaries for this exact Node version, it falls back to compiling from source, requiring `node-gyp` + Python + C++ compiler. This is exactly why graceful fallback (R002) is critical. Verified: `npm install better-sqlite3` succeeds on the target platform without compilation. -- **Package distribution impact**: Adding `better-sqlite3` to `optionalDependencies` increases npm package size by ~5MB (prebuilt native addon). This is acceptable for the token savings it delivers, but worth noting. -- **Schema evolution between S01 and S02**: S01 defines the schema for decisions and requirements only. S02 will add tables for roadmaps, plans, summaries, etc. The migration system must handle adding tables to an existing DB without data loss. Design the migration runner to handle version 1→2→3→...N upgrades. -- **In-memory WAL verification gap**: As noted in pitfalls, in-memory DBs don't actually use WAL mode. The R020 requirement (WAL enabled) needs a file-based test to truly verify. The platform proof-of-concept confirmed WAL works on file-based DBs. +- **`better-sqlite3` native build on exotic platforms** — Prebuilt binaries may not cover Alpine Linux, musl libc, or unusual architectures. These platforms require `node-gyp` + build tools (`python3`, `make`, `gcc`/`g++`). The graceful fallback (R002) makes this a non-fatal degradation. Low risk for typical use. +- **Schema evolution across slices** — S01 creates decisions + requirements tables. S02–S03 add 8+ more tables (milestones, slices, tasks, roadmaps, plans, summaries, contexts, research). Schema migrations via `user_version` must handle incremental additions without data loss. Use `CREATE TABLE IF NOT EXISTS` for new tables and `ALTER TABLE ADD COLUMN` for additions to existing tables. +- **`node:sqlite` stabilization** — Available in Node 22 as experimental (prints warning). If it stabilizes and becomes the standard, `better-sqlite3` becomes unnecessary tech debt. Low risk — D001 is non-revisable, and the fallback architecture means swapping implementations later is straightforward. The API surface is similar. +- **Two SQLite libraries in the project** — `sql.js` (memory extension) and `better-sqlite3` (GSD DB). Different extensions, different loading patterns, no conflict. Could eventually consolidate but out of scope for M001. +- **Process crash leaving DB in unexpected state** — WAL mode handles this gracefully — SQLite replays the WAL on next open. No special recovery code needed. The sidecar files are harmless artifacts of an incomplete checkpoint. ## Skills Discovered | Technology | Skill | Status | |------------|-------|--------| -| SQLite / better-sqlite3 | `martinholovsky/claude-skills-generator@sqlite database expert` | available (544 installs) | +| SQLite | `martinholovsky/claude-skills-generator@sqlite-database-expert` | available (544 installs) — general SQLite expertise, not specific to better-sqlite3.

The current `stopAuto` already calls `teardownAutoWorktree`, but it does so **without squash-merging first** — it just removes the worktree and deletes the milestone branch. This is the critical gap. + +The implementation requires: (1) a `mergeMilestoneToMain` function that checks out main in the original project root, squash-merges the milestone branch, commits with a rich message listing all slices, and optionally auto-pushes; (2) rewiring `stopAuto` (or the complete-milestone post-path) to call this merge before teardown; (3) modifying `teardownAutoWorktree` to optionally preserve the branch (since we need it alive for the squash-merge, then delete it after). + +The existing `mergeSliceToMain` in git-service.ts is a useful pattern reference but has ~60 lines of `.gsd/` conflict resolution that are unnecessary for milestone squash. The new function should be clean and simple — the milestone branch already has all slices merged via `--no-ff`, so the squash just flattens the whole thing into one commit on main. + +## Recommendation + +Add `mergeMilestoneToMain(originalBasePath, milestoneId, roadmapSlices)` to `auto-worktree.ts` (co-located with the rest of the worktree lifecycle, consistent with D037).

The squash-merge needs the branch alive. Either: (a) merge before teardown and pass `deleteBranch: false`, then delete after merge; or (b) restructure teardown to not delete the branch. +- `stopAuto` is called from ~20 places in auto.ts. The milestone squash should only happen on the `complete` phase path — not on error stops, pause, or other exit paths. +- Auto-push must use the same `auto_push` / `remote` preferences as existing push code. +- The milestone branch might have uncommitted changes from the complete-milestone unit's summary write. Must auto-commit before squash-merge. + +## Common Pitfalls + +- **Double teardown** — if `mergeMilestoneToMain` tears down the worktree and then `stopAuto` tries again, it'll error or no-op. Make `stopAuto`'s teardown conditional on `isInAutoWorktree()` (it already checks this, so it should be safe, but verify). +- **Dirty worktree at merge time** — the complete-milestone unit writes `M003-SUMMARY.md` and other files. These must be committed on the milestone branch before the squash-merge. Auto-commit in the worktree before chdir-ing out. +- **Branch doesn't exist after removeWorktree** — `removeWorktree` defaults to `deleteBranch: true`. Must pass `deleteBranch: false` or restructure the call order. +- **Squash-merge with no changes** — if milestone branch has no diff vs main (e.g., all changes were already cherry-picked), `git merge --squash` succeeds but `git commit` fails with "nothing to commit". Handle this gracefully. +- **originalBasePath is null** — if `getAutoWorktreeOriginalBase()` returns null during the complete path, the merge can't proceed. This shouldn't happen (we're in a worktree), but guard against it. + +## Open Risks + +- **Remote divergence** — if main has advanced on the remote since the worktree was created, `git pull --rebase` before merge could conflict. The existing `mergeSliceToMain` does a pull before merge; replicate that pattern. +- **Long-running milestone with main drift** — if someone pushes to main during a multi-day milestone, the squash-merge could have conflicts.
