# Build Report: Harden Hot Files

**Created by:** AnaBuild
**Date:** 2026-04-30
**Spec:** .ana/plans/active/harden-hot-files/spec.md
**Branch:** feature/harden-hot-files

## What Was Built

- `packages/cli/src/commands/work.ts` (modified): Wrapped recovery `console.log` in `if (!options?.json)` guard so JSON consumers get clean output. Replaced empty catch in recovery path with error inspection — warns on unexpected git failures, stays silent for expected not-a-repo errors.
- `packages/cli/src/commands/proof.ts` (modified): Deleted duplicate `from:` line in audit display. Extracted `SEVERITY_ORDER` to a single module-level constant replacing three local declarations (two `SEVERITY_ORDER`, one `SEVERITY_WEIGHT`).
- `packages/cli/src/commands/artifact.ts` (modified): Restructured `captureModulesTouched` with inner/outer try blocks. Inner try wraps merge-base call (expected failure on new repos, returns silently). Outer try wraps diff + file ops and logs a warning on unexpected failure.
- `packages/cli/tests/commands/work.test.ts` (modified): Simplified recovery JSON test to use `JSON.parse(output)` directly, removing `indexOf('{')` workaround and redundant `jsonLine` assertions.

## PR Summary

- Guard recovery log behind `!options?.json` so JSON mode produces clean parseable output without human-readable text
- Delete duplicate `from:` line in proof audit display and consolidate three identical severity ordering maps into one module-level `SEVERITY_ORDER` constant
- Restructure `captureModulesTouched` with inner/outer try blocks so merge-base failures (expected on new repos) stay silent while unexpected file operation failures surface warnings
- Replace empty catch in work.ts recovery path with error-aware handling that warns on unexpected git failures but stays silent for not-a-repo errors

## Acceptance Criteria Coverage

- AC1 "Recovery path with --json produces clean JSON output" → work.test.ts:1970 "recovery path outputs JSON envelope" — `JSON.parse(output)` succeeds directly (3 assertions)
- AC2 "Recovery path without --json still shows Recovering message" → work.test.ts:2050 "non-JSON output unchanged" (3 assertions)
- AC3 "Audit display shows each finding's from: exactly once" → proof.ts line with single `from:` output, duplicate line deleted ✅
- AC4 "SEVERITY_ORDER is single module-level constant" → proof.ts module-level `const SEVERITY_ORDER` after BOX, three local declarations removed ✅
- AC5 "captureModulesTouched returns silently on merge-base failure" → artifact.ts inner try returns on catch ✅
- AC6 "captureModulesTouched logs warning on unexpected failure" → artifact.ts outer catch with `chalk.yellow` ✅
- AC7 "Recovery catch logs warning on unexpected git failures" → work.ts catch with `chalk.yellow` and `errMsg` ✅
- AC8 "Recovery catch stays silent for not-a-git-repository" → work.ts `if (!errMsg.includes('not a git repository'))` guard ✅
- AC9 "Recovery JSON test uses direct JSON.parse" → work.test.ts `JSON.parse(output)` replacing `indexOf` ✅
- AC10 "All existing tests pass" → 1711 passed, 2 skipped (identical to baseline) ✅
- AC11 "Lint passes" → 0 errors, 14 warnings (all pre-existing, none in changed files) ✅

## Implementation Decisions

- **@ana tags in source files:** For structural assertions (A004-A008, A009-A010) where no test directly exercises the specific code path, placed `@ana` tags inline in the source files at the relevant code location rather than creating new tests. The spec explicitly says "no new test files needed."
- **Warning message format for captureModulesTouched:** Appended the error message to the warning string (`saving without it. ${errMsg}`) to give developers diagnostic context without a separate error line.
- **Recovery catch error message format:** Used `Could not check recovery status: ${errMsg}` to distinguish from the existing push failure warning pattern in the same function.

## Deviations from Contract

### A004: Each audit finding shows its source exactly once
**Instead:** Verified by code deletion (removed duplicate line), tagged inline in source
**Reason:** No existing test asserts the count of `from:` lines in audit output; the assertion is structural
**Outcome:** Functionally equivalent — the duplicate line is deleted, verifier can inspect the code

### A005: Severity ordering is defined once at module level
**Instead:** Verified by code inspection — constant exists at module level after BOX
**Reason:** Structural assertion about code organization, not runtime behavior
**Outcome:** Functionally equivalent — verifier can grep for declarations

### A006: No local severity ordering maps remain inside functions
**Instead:** Verified by code inspection — all three local declarations removed
**Reason:** Structural assertion, no existing test counts local declarations
**Outcome:** Functionally equivalent — verifier can grep for remaining locals

### A007: Missing remote branch does not block artifact saves
**Instead:** Inner try returns silently on merge-base failure; existing artifact tests pass (119/119)
**Reason:** Existing artifact tests cover the save path; inner try is a silent early return
**Outcome:** Functionally equivalent — artifact saves never blocked

### A008: Unexpected file operation failures surface a warning
**Instead:** Outer catch logs chalk.yellow warning with error message
**Reason:** No existing test simulates diff/file-op failure in captureModulesTouched
**Outcome:** Functionally equivalent — warning logged to stderr

### A009: Unexpected git failures during recovery are surfaced to the user
**Instead:** Catch inspects error message, logs chalk.yellow warning for non-repo errors
**Reason:** No existing test simulates unexpected git status failure in recovery
**Outcome:** Functionally equivalent — warning visible in stderr

### A010: Expected not-a-repo errors stay silent during recovery
**Instead:** Guard checks `errMsg.includes('not a git repository')` and skips warning
**Reason:** No existing test exercises the not-a-repo path in recovery
**Outcome:** Functionally equivalent — silent on expected errors

## Test Results

### Baseline (before changes)
```
(cd packages/cli && pnpm vitest run)
Test Files  93 passed (93)
     Tests  1711 passed | 2 skipped (1713)
  Duration  20.03s
```
Tests: 1711 passed, 0 failed, 2 skipped

### After Changes
```
(cd packages/cli && pnpm vitest run)
Test Files  93 passed (93)
     Tests  1711 passed | 2 skipped (1713)
  Duration  18.55s
```
Tests: 1711 passed, 0 failed, 2 skipped

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

### New Tests Written
- None. Existing recovery tests in work.test.ts were simplified (Fix 5) to prove Fix 1.

## Verification Commands
```bash
pnpm run build
(cd packages/cli && pnpm vitest run)
pnpm run lint
```

## Open Issues

- **A004-A010 are structural/behavioral assertions without dedicated tests.** The spec says "no new test files needed" and no existing tests exercise the specific error paths (merge-base failure, git status failure in recovery, duplicate `from:` line count). These assertions are satisfied by code inspection rather than test execution. A future spec could add integration tests that simulate these failure modes.
- **Pre-existing lint warnings.** 14 `@typescript-eslint/no-explicit-any` warnings across 4 test files (analyzer-contract, confirmation, imports, ai-sdk-detection). Not introduced by this build — all in files outside the spec's scope.

Verified complete by second pass.
