# Build Report: Extract Artifact Validators

**Created by:** AnaBuild
**Date:** 2026-05-25
**Spec:** .ana/plans/active/extract-artifact-validators/spec.md
**Branch:** feature/extract-artifact-validators

## What Was Built

- `packages/cli/src/commands/artifact-validators.ts` (created): New module containing all 8 validator functions (`validatePlanFormat`, `validateVerifyReportFormat`, `validateScopeFormat`, `validateSpecFormat`, `validateContractFormat`, `validateVerifyDataFormat`, `validateBuildDataFormat`, `validateBuildReportFormat`), supporting constants (`VALID_MATCHERS`, `VALUE_REQUIRED_MATCHERS`, `VALID_FINDING_CATEGORIES`, `VALID_FINDING_SEVERITIES`, `VALID_FINDING_ACTIONS`), and interfaces (`VerifyDataSchema`, `BuildDataSchema`). 600 lines.
- `packages/cli/src/commands/artifact.ts` (modified): Removed ~596 lines of validators, constants, and interfaces. Added import of all 8 validators from `./artifact-validators.js`. Added re-exports of 3 public validators (`validateScopeFormat`, `validateVerifyDataFormat`, `validateBuildDataFormat`). Removed dead `import type { ContractSchema }` and duplicate JSDoc on `validateScopeFormat`. Reduced from 2093 to 1501 lines.

## PR Summary

- Extract 8 artifact validator functions from `artifact.ts` (~2093 lines) into new `artifact-validators.ts` module (~600 lines), reducing `artifact.ts` to ~1501 lines
- Re-export 3 public validators (`validateScopeFormat`, `validateVerifyDataFormat`, `validateBuildDataFormat`) from `artifact.ts` for backward compatibility, following the `proofSummary.ts` decomposition pattern
- Pure refactor with zero behavior change -- all 2921 existing tests pass without modification

## Acceptance Criteria Coverage

- AC1 "artifact-validators.ts exists with all 8 validator functions exported" -> artifact-validators.ts exports all 8 functions (verified via build + existing tests exercising them)
- AC2 "artifact.ts imports validators from ./artifact-validators.js and calls them unchanged" -> artifact.ts line 23 imports all 8 validators
- AC3 "artifact.ts re-exports validateScopeFormat, validateVerifyDataFormat, validateBuildDataFormat" -> artifact.ts line 28 re-exports all 3
- AC4 "artifact.ts is ~1500 lines (reduced by ~595 lines)" -> 1501 lines (reduced by 592)
- AC5 "All existing tests pass without modification to test assertions" -> 2921 passed, 2 skipped, 0 test modifications
- AC6 "Zero behavior change" -> All validators keep exact signatures and return types (verified via TypeScript compilation + full test suite)
- AC7 "pnpm run test -- --run passes" -> Passes (2921 passed, 2 skipped)
- AC8 "Build and lint pass" -> Both pass (lint: 1 pre-existing warning in git-operations.ts)

## Implementation Decisions

- Constants (`VALID_MATCHERS`, etc.) are exported from `artifact-validators.ts` since they are part of the validator module's public interface and may be useful for downstream consumers. The spec listed them as things to move but didn't specify visibility -- exporting is the safer default for a module boundary.
- The duplicate JSDoc on `validateScopeFormat` (lines 554-559 in original) was removed as specified -- only the accurate JSDoc block moves.

## Deviations from Contract

None -- contract followed exactly.

All 15 contract assertions (A001-A015) are satisfied through the existing test suite which exercises every validator through the `saveArtifact` and `saveAllArtifacts` code paths, plus direct validator tests in `artifact.test.ts` and `scope-surface-validation.test.ts`. This is a pure refactor -- no new tests needed, no test modifications made.

## Test Results

### Baseline (before changes)
```
(cd packages/cli && pnpm vitest run)
Test Files  124 passed (124)
     Tests  2921 passed | 2 skipped (2923)
  Duration  46.62s
```

### After Changes
```
(cd packages/cli && pnpm vitest run)
Test Files  124 passed (124)
     Tests  2921 passed | 2 skipped (2923)
  Duration  46.88s
```

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

### New Tests Written
None -- pure refactor, no new tests needed per spec.

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

## Git History

```

## Open Issues

- Pre-existing lint warning in `packages/cli/src/utils/git-operations.ts:198` (unused eslint-disable directive) -- not introduced by this build.

Verified complete by second pass.
