Phase 01 — D1 Setup — Implementation Report

Files Created

src/db/sql-store-interface.js — JSDoc typedefs for SqlStore/SqlRunResult
src/db/cf-sql-store.js — CFSqlStore class wrapping env.DB prepare/run/all/first/batch
src/db/create-sql-store.js — factory; returns null when env.DB absent, SqlStore otherwise; exposes tablePrefix
tests/fakes/fake-d1.js — in-memory D1 fake with seed(), runLog, queryLog; naive table extraction from SQL text
tests/db/create-sql-store.test.js — 13 tests: validation, tablePrefix, run/all/first/batch round-trips
scripts/migrate.js — custom migration runner; walks src/modules//migrations/.sql sorted, tracks applied in _migrations table, supports --dry-run and --local flags

src/modules/registry.js — added createSqlStore import; passes sql: createSqlStore(mod.name, env) into init alongside db
wrangler.toml — added d1_databases block; database_id = REPLACE_ME_D1_UUID (requires manual fill after wrangler d1 create)
package.json — added "db:migrate": "node scripts/migrate.js"; chained into deploy: wrangler deploy && npm run db:migrate && npm run register

dispatcher.js: no change needed — it delegates entirely to buildRegistry which already handles init; spec note resolved.
basename import in migrate.js kept (unused but Biome didn't flag it as unused import — left for future use). Actually removed by format — clean.

npm test: 118/118 pass (12 files)
npm run lint: clean (0 errors)
register:dry: exits with "not found" for .env.deploy — expected in dev, no code regression

wrangler.toml placeholder REPLACE_ME_D1_UUID must be replaced with real UUID from npx wrangler d1 create miti99bot-db before deploying.
fake-d1 is a minimal fake (no SQL parser); tests that need real SQL semantics should use better-sqlite3 or Miniflare.
