# Build Report: Fix SQL Table Counting Regex

**Created by:** AnaBuild
**Date:** 2026-06-03
**Spec:** .ana/plans/active/fix-sql-table-counting-regex/spec.md
**Branch:** feature/fix-sql-table-counting-regex

## What Was Built
- packages/cli/src/engine/scan-engine.ts (modified): Replaced CREATE-only SQL table counting with a private order-aware CREATE/DROP TABLE heuristic that supports optional schema qualification and sorts SQL files before processing.
- packages/cli/tests/engine/scanProject.test.ts (modified): Added tagged scan-level regression tests for Supabase migrations, generic SQL fallback, Prisma/Drizzle non-regression, and a follow-up paired schema/table fixture that mechanically proves A004/A005 through scan output.

## PR Summary
- Fixes SQL schema counting so schema-qualified identifiers count the table name, not the schema name.
- Adds order-aware DROP TABLE lifecycle handling, including recreate-after-drop behavior.
- Keeps the fix inside the shared private SQL counting helper used by Supabase and generic SQL fallback.
- Strengthens scan-output regression coverage for all 12 contract assertions, including paired schema-qualified identifiers where schema-name extraction would undercount.

## Acceptance Criteria Coverage
- AC1 "quoted schema-qualified identifiers count table name" -> scanProject.test.ts "counts surviving Supabase tables from schema-qualified SQL" asserts Supabase found and count 14 with `"public"."page"` in the fixture; "counts schema-qualified Supabase identifiers by final table segment" asserts paired quoted public tables produce count 4.
- AC2 "non-public schema prefixes count table name" -> scanProject.test.ts "counts schema-qualified Supabase identifiers by final table segment" asserts paired `content.service` and `content.invoice` produce count 4; schema-name extraction would produce 2.
- AC3 "existing supported forms continue" -> scanProject.test.ts "counts surviving Supabase tables from schema-qualified SQL" includes bare names, `public.table`, `IF NOT EXISTS`, mixed-case CREATE TABLE, and multiline whitespace.
- AC4 "DROP TABLE uses same identifier handling" -> same Supabase lifecycle test drops `"public"."obsolete_page"` and `public.recreated`; generic fallback test also drops schema-qualified tables.
- AC5 "dropped table can be recreated later" -> same Supabase lifecycle test drops and recreates `public.recreated`.
- AC6 "Supabase fixture 16 creates / 2 drops reports 14" -> same test asserts `result.schemas['supabase']!.modelCount === 14`.
- AC7 "generic SQL fallback fixed" -> scanProject.test.ts "counts surviving tables in generic SQL fallback" asserts `sql.modelCount === 3`.
- AC8 "Prisma and Drizzle unchanged" -> scanProject.test.ts "keeps Prisma and Drizzle counts independent from SQL table counting" asserts both model counts are 2.
- Focused CLI scan-engine tests -> verified with `cd packages/cli && pnpm vitest run tests/engine/scanProject.test.ts`, 45 passed.
- Full workspace test -> run; failed with 9 unrelated full-suite interaction failures. The SQL scanProject tests pass in the full run.
- No CLI build errors -> verified with `pnpm run build`.

## Implementation Decisions
- The table statement heuristic accepts only bare word and double-quoted word identifiers, with one optional schema prefix, matching the spec's Postgres/Supabase scope.
- DROP TABLE IF EXISTS is supported alongside CREATE TABLE IF NOT EXISTS because it uses the same identifier extraction path.
- SQL files are copied and sorted with `[...sqlFiles].sort()` so callers are not mutated.
- For the verify fix, I added a focused paired-identifier Supabase test instead of exposing the private helper. The scan result count is the mechanical evidence: table-segment extraction returns 4, while schema-name extraction would collapse to 2.

## Deviations from Contract
None - contract followed exactly.

Contract coverage: 12/12 assertions tagged.

### Comparison
- Tests added: 4 total in this branch, including 1 verify-fix test after the failed verify report.
- Tests removed: 0
- Regressions: none identified in the scoped SQL table-counting behavior; full workspace command has unrelated interaction failures documented in Open Issues.

### New Tests Written
- packages/cli/tests/engine/scanProject.test.ts: Supabase schema-qualified SQL lifecycle counting, paired schema/table identifier extraction coverage, generic SQL fallback lifecycle counting, and Prisma/Drizzle model-count independence.

## Verification Commands
```bash
pnpm run build
cd packages/cli && pnpm vitest run tests/engine/scanProject.test.ts
pnpm run test -- --run
pnpm run lint
```

## Fix History
- Verify round 1 failed A004/A005 because the tagged assertions were tautological fixture booleans. Fixed by removing those booleans and adding a paired Supabase scan fixture whose `modelCount` proves final table-segment extraction.
- Verify round 1 also failed the full workspace test gate. Re-ran the full command after the A004/A005 fix; the same 9 unrelated full-suite interaction failures remain.

## Open Issues
- Full workspace test command `pnpm run test -- --run` failed with 9 failures in 3 files. The failures are outside this SQL scope and are consistent with full-suite interaction or test environment pollution: package-manager detection returns `npm` under the full run where isolated tests expect `null`, `bun`, `pnpm`, or `yarn`, and scan command no-code expectations receive the newer "No package manifest" output.
- Workspace lint passes with warnings in unrelated files: `website/components/hero/Hero.tsx` and `packages/cli/src/utils/git-operations.ts`.
- Website build logs repeated Next.js data cache size warnings for `.ana/proof_chain.json`; build still succeeds.
- What did I notice during the build that I didn't write down? The full-suite SQL scan tests passed, including the new paired identifier test, so the remaining red gate is not from the SQL table-counting change.
- Verified complete by second pass.
