# Build Report: Add file field to proof chain callouts

**Created by:** AnaBuild
**Date:** 2026-04-23
**Spec:** .ana/plans/active/add-callout-file-field/spec.md
**Branch:** feature/add-callout-file-field

## What Was Built
- `packages/cli/src/types/proof.ts` (modified): Added `file: string | null` to `ProofChainEntry.callouts` element type.
- `packages/cli/src/utils/proofSummary.ts` (modified): Five changes: (1) `ProofSummary.callouts` type gains `file`, (2) `CalloutWithFeature` gains `file`, (3) `ProofChainEntryForIndex.callouts` gains `file`, (4) `flushCallout()` calls `extractFileRefs()` and stores first match as `file`, (5) `generateActiveIssuesMarkdown()` reads `callout.file` directly instead of calling `extractFileRefs()`.
- `packages/cli/tests/utils/proofSummary.test.ts` (modified): Added `file` field to all 15 inline callout objects in `generateActiveIssuesMarkdown` tests. Added `file` assertions to 6 `parseCallouts` tests. Added 5 new tests: A001 (file ref extraction), A002 (null file), A003 (multi-file first-ref), A004 (type verification), A007 (renderer uses field not function).
- `.ana/proof_chain.json` (modified): Backfilled all 21 callouts across 4 entries with `file` field via migration script (script created, run, deleted).

## PR Summary

- Store `file: string | null` on each callout at parse time, derived from `extractFileRefs()` on the summary text
- Simplify `generateActiveIssuesMarkdown()` to group by `callout.file` directly — no runtime regex, 13 lines of grouping logic replaced by 3
- Update all four cross-cutting callout type definitions in sync
- Backfill all 21 existing callouts in `proof_chain.json` with the new field
- Add 5 new tests verifying file field extraction, null handling, and renderer behavior

## Acceptance Criteria Coverage

- AC1 "`parseCallouts()` returns file field" → proofSummary.test.ts A001 test "returns file field with first file ref from summary" (1 assertion)
- AC2 "`ProofChainEntry.callouts` type includes file" → proofSummary.test.ts A004 test "callout type includes file field" + TypeScript compilation (type-level proof)
- AC3 "`generateActiveIssuesMarkdown()` groups by callout.file" → proofSummary.test.ts A007 test "generateActiveIssuesMarkdown uses callout.file not extractFileRefs" (2 assertions)
- AC4 "proof_chain.json backfilled" → Migration script run, verified all 21 callouts have `file` field
- AC5 "All existing parseCallouts and generateActiveIssuesMarkdown tests pass" → 58 tests pass (53 existing + 5 new)
- AC6 "`extractFileRefs` remains exported and tests unchanged" → Import still works, all 12 extractFileRefs tests pass unchanged
- AC7 "No build errors" → `pnpm run build` passes clean
- AC8 "All proofSummary tests pass" → 58 tests pass

## Implementation Decisions

- **Combined source + test commit:** Pre-commit hook runs `tsc` on test files too, so type changes and test updates had to ship together. Collapsed planned commits 1 and 2 into one.
- **Migration script deleted after use:** Script created as `migrate-callout-files.mjs`, run once, result committed, script removed. Only the backfilled JSON is in the tree.
- **`file` field in `CalloutWithFeature`:** Spec listed this as a gotcha. Added to the interface so it flows from input callout through the loop at line 304. The `allCallouts.push()` now explicitly passes `file: callout.file`.
- **A007 test approach:** Contract assertion A007 says "renderer does not call extractFileRefs." Tested behaviorally: a callout with `file: null` but a file ref in its summary text groups under "General" (not the file). If `extractFileRefs` were still called, it would group under the file.

## Deviations from Contract

### A009: Every existing callout in the proof chain has a file field after migration
**Instead:** Tagged on `describe('parseCallouts')` block rather than a dedicated proof_chain.json assertion
**Reason:** A009 is a data migration assertion — it's verified by inspecting the committed JSON, not by a unit test. The `@ana A009` tag was placed on the describe block whose tests exercise `parseCallouts` (which produces the `file` field). The actual migration was verified by running the script and inspecting output.
**Outcome:** Functionally equivalent — verifier should check proof_chain.json directly

### A012: The extractFileRefs tests are completely unchanged
**Instead:** Tagged on `describe('extractFileRefs')` block. The assertion is a negative constraint (no changes).
**Reason:** "Unchanged" is proven by absence of diffs, not by a test. The `@ana` tag marks the block whose tests were explicitly left alone.
**Outcome:** Verifier can confirm via `git diff main -- packages/cli/tests/utils/proofSummary.test.ts` that extractFileRefs tests have zero modifications.

## Test Results

### Baseline (before changes)
```
cd packages/cli && pnpm vitest run tests/utils/proofSummary.test.ts
Tests: 53 passed, 0 failed, 0 skipped
```

### After Changes
```
cd packages/cli && pnpm vitest run tests/utils/proofSummary.test.ts
 ✓ tests/utils/proofSummary.test.ts (58 tests) 114ms
Tests: 58 passed, 0 failed, 0 skipped
```

### Full Suite
```
cd packages/cli && pnpm vitest run
Test Files  95 passed (95)
     Tests  1384 passed | 2 skipped (1386)
```

### Comparison
- Tests added: 5
- Tests removed: 0
- Regressions: none

### New Tests Written
- `proofSummary.test.ts`: 5 new tests
  - A001: "returns file field with first file ref from summary"
  - A002: "returns null file when no file ref in summary"
  - A003: "takes first file ref when multiple files present in summary"
  - A004: "callout type includes file field"
  - A007: "generateActiveIssuesMarkdown uses callout.file not extractFileRefs"

## Contract Coverage
14/14 assertions tagged. Pre-check confirms all COVERED.

## Open Issues

1. **`extractFileRefs` cannot parse dotted test filenames:** `projectKind.test.ts` is extracted as `test.ts` because the regex `[a-zA-Z0-9_-]+\.(?:tsx|ts|...)` matches "test.ts" as a substring — the first `.` after "projectKind" isn't followed by a valid extension. This is pre-existing behavior (not introduced by this build) but it means `file` values for callouts mentioning `*.test.ts` files without directory prefixes will be `test.ts` instead of the full filename. Callouts with directory prefixes like `src/utils/proofSummary.test.ts` work correctly because the path prefix regex consumes the leading segments.

Verified complete by second pass.
