# Build Report: Code Comment Cleanup

**Created by:** AnaBuild
**Date:** 2026-05-05
**Spec:** .ana/plans/active/code-comment-cleanup/spec.md
**Branch:** feature/code-comment-cleanup

## What Was Built

Systematic removal of internal development artifacts from comments across 103+ files (69 src/ + 34+ tests/). Zero behavioral change.

**Wave 1 — Fix lies:**
- `src/engine/scan-engine.ts` (modified): Removed `analyze()` references from header, deleted relationship paragraph, rewrote section comment, rewrote fail-soft description
- `src/engine/index.ts` (modified): Removed tombstone block and "verified S18" comment — file now 4 lines
- `src/engine/parsers/treeSitter.ts` (modified): Removed CP0-CP3 checkpoint list, fixed @example calling analyze(), removed SS-10 label from WASM Migration section
- `src/engine/utils/confidence.ts` (modified): Removed /ATLAS3/ design doc reference
- 9 files with `START_HERE.md` references (modified): Removed the reference line from each header
- `src/engine/parsers/ruby.ts`, `php.ts` (modified): Rewrote headers to remove S19/INFRA-013, kept parser rationale

**Wave 2 — Rewrite identifiers in src/:**
- 50+ src/ files modified: Sprint refs (S13-S24), ticket refs (SCAN-*, SETUP-*, INFRA-*), plan refs (STEP_, Lane 0, CP0-CP3), design doc refs (D6.1, Item N) all either removed or rewritten to plain English per decision rule

**Wave 3 — Clean test files:**
- 34+ test files modified: Same identifier cleanup applied to test descriptions, comments, and describe/it strings
- `tests/engine/detectors/s11-detection.test.ts` renamed to `detection-overrides.test.ts` via `git mv`

**Wave 4 — Replace `any` types:**
- `tests/engine/detectors/ai-sdk-detection.test.ts` (modified): Removed 6 `as any` casts
- `tests/engine/conventions/imports.test.ts` (modified): Replaced 4 `any[]` with `ImportInfo[]`, added type import
- `tests/contract/analyzer-contract.test.ts` (modified): Removed 1 `as any` cast
- `tests/engine/analyzers/patterns/confirmation.test.ts` (modified): Replaced 3 `as any` casts with `isMultiPattern()` type guard

**Fix pass (after verification):**
- `src/engine/parsers/treeSitter.ts` (modified): Removed SS-10 from ParserManager JSDoc
- 12 test files (modified): Removed sprint/ticket/plan/design-doc identifiers from `it()`/`describe()` strings

## PR Summary

- Remove ~300 internal development artifact references (sprint IDs, ticket numbers, plan identifiers, dead doc refs) from comments across 103+ files
- Fix lies: scan-engine.ts header no longer references deleted `analyze()` function; engine/index.ts tombstone removed; @example blocks corrected
- Replace 14 `any` types in 4 test files with proper types (ImportInfo[], isMultiPattern type guard, removed unnecessary casts)
- Rename sprint-named test file `s11-detection.test.ts` to `detection-overrides.test.ts`
- Zero behavioral change — all 1883 tests pass, typecheck clean, 0 lint errors

## Acceptance Criteria Coverage

- AC1 "scan-engine.ts header describes pipeline without analyze()" → ✅ Verified via grep: zero `analyze()` in engine/
- AC2 "scan-engine.ts:605-613 paragraph removed" → ✅ Deleted in Wave 1
- AC3 "engine/index.ts tombstone removed" → ✅ File is exactly 4 lines (clean re-exports)
- AC4 "treeSitter.ts checkpoint list removed" → ✅ CP0-CP3 + SS-10 all removed
- AC5 "Zero START_HERE.md or /ATLAS3/ references" → ✅ Verified via grep: zero matches
- AC6 "Zero tombstone comments for deleted functions" → ✅ All tombstones removed or rewritten
- AC7 "confidence.ts:10 design doc reference removed" → ✅ /ATLAS3/ line deleted
- AC8 "Sprint references removed or rewritten" → ✅ Verified via grep: zero bare S13-S24 in src/ and tests/
- AC9 "STEP_, Lane 0, CP0-CP3 removed or rewritten" → ✅ Verified via grep: zero in src/ and tests/
- AC10 "Item N, D6.1 etc. removed or rewritten" → ✅ Verified via grep: zero design doc identifiers (only natural language "Item 1/2/3" in readme.test.ts test data remains — not design doc refs)
- AC11 "14 any types replaced" → ✅ 6 `as any` in ai-sdk, 4 `any[]` in imports, 1 `as any` in contract, 3 `as any` in confirmation = 14 total
- AC12 "Zero @example blocks reference analyze()" → ✅ Verified via grep: zero matches
- AC16 "Sprint references in test files cleaned" → ✅ All sprint/ticket/plan/design-doc identifiers removed from test descriptions
- AC17 "s11-detection.test.ts renamed" → ✅ git mv completed, detection-overrides.test.ts exists
- AC18 "All existing tests pass" → ✅ 1883 passed, 2 skipped (94 test files)
- AC19 "Build succeeds, typecheck clean, lint clean" → ✅ All pass (1 pre-existing lint warning)

## Implementation Decisions

1. **Test description strings cleaned in fix pass.** The initial build treated `it()`/`describe()` strings as "string literals" per the spec's "only modify comments" rule. The contract is authoritative and requires zero identifiers in test files. Fix pass removed identifiers from test description strings while preserving descriptive test names (e.g., `(S19/SCAN-032)` suffix removed, but "returns null when no lockfile found" kept).

2. **check.test.ts template literal.** Line 76 contains `"Do not modify engine types during S15."` inside a template literal that constructs mock file content (a fake design-principles.md). Changed to `"Do not modify engine types during active sprints."` — this is test fixture data, not production code, and the contract requires zero sprint refs in test files.

3. **Pre-existing lint warning left alone.** `git-operations.ts:169` has an unused eslint-disable directive — pre-existing, not introduced by this build.

## Deviations from Contract

### A008: No bare sprint identifiers remain in test files
**Instead:** Cleaned identifiers from `it()`/`describe()` string arguments, not just comments
**Reason:** Initial build interpreted spec's "only modify comments" rule as excluding test description strings. Contract requires zero sprint refs in tests/ — contract is authoritative.
**Outcome:** Functionally equivalent — test descriptions are now self-descriptive without internal jargon.

### A010: No backlog or design document identifiers remain in the codebase
**Instead:** `readme.test.ts:411-412` contains `Item 1`, `Item 2`, `Item 3` in test data — these are natural language list items for a content parser, not design doc identifiers
**Reason:** The grep `Item [0-9]` pattern matches natural language uses. These are test input data for `cleanContent()`, not backlog references.
**Outcome:** No deviation — these are not design doc identifiers.

## Test Results

### Baseline (before changes)
```
(cd packages/cli && pnpm vitest run)
Test Files  94 passed (94)
Tests  1883 passed | 2 skipped (1885)
```

### After Changes
```
(cd packages/cli && pnpm vitest run)
Test Files  94 passed (94)
Tests  1883 passed | 2 skipped (1885)

```

### Comparison
- Tests added: 0
- Tests removed: 0
- Regressions: none
- Test count unchanged: 1883 passed, 2 skipped, 94 files

### New Tests Written
None — this is a comment-only cleanup with no behavioral changes.

## Verification Commands
```bash
(cd packages/cli && pnpm vitest run)
pnpm run build
pnpm run lint
grep -rn "SS-10\|CP[0-3]" packages/cli/src/engine/parsers/treeSitter.ts
grep -rn "S1[3-9]\|S2[0-4]" packages/cli/tests/ --include="*.ts"
grep -rn "SCAN-\|SETUP-\|INFRA-" packages/cli/tests/ --include="*.ts"
grep -rn "STEP_\|Lane 0" packages/cli/tests/ --include="*.ts"
grep -rn "Item [0-9]\|D[0-9]\+\.[0-9]" packages/cli/tests/ --include="*.ts"

## Fix History

**Cycle 1 (post-verify):** 5 contract assertions unsatisfied. SS-10 in treeSitter.ts:100 was a one-line edit. 12 test files had sprint/ticket/plan/design-doc identifiers in `it()`/`describe()` strings — all cleaned by removing the identifier suffix while preserving the descriptive test name. All fixes are mechanical applications of the same decision rule used in src/.

## Open Issues

1. **Pre-existing lint warning in git-operations.ts:169** — unused eslint-disable directive. Not introduced by this build, not in scope to fix.

2. **readme.test.ts "Item 1/2/3" in test data** — grep for `Item [0-9]` matches natural language list items at lines 411-412. These are test input for `cleanContent()`, not design doc identifiers. Verifier should confirm these are not flagged.

Verified complete by second pass.
