# Build Report: Extract Proof Command Handlers

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

## What Was Built

- `packages/cli/src/commands/proof.ts` (modified): Extracted 8 inline `.action()` handlers from `registerProofCommand` into standalone named functions (`handleProofList`, `handleProofContext`, `handleProofClose`, `handleProofPromote`, `handleProofStrengthen`, `handleProofAudit`, `handleProofHealth`, `handleProofStale`). Replaced `proofCommand.opts()['json']` closure dependency with explicit `parentJson: boolean` parameter in 7 subcommand handlers. `registerProofCommand` shrank from ~1687 lines to 95 lines of command declarations with thin arrow-function wrappers. All handler bodies moved verbatim — only the `parentOpts`/`useJson` pattern was replaced.

## PR Summary

- Extract 8 inline action handlers from `registerProofCommand` into standalone named functions in proof.ts
- Replace `proofCommand.opts()['json']` closure dependency with explicit `parentJson: boolean` parameter forwarded through thin arrow-function wrappers
- Shrink `registerProofCommand` from ~1687 lines to 95 lines — it now reads as a table of contents for the proof subcommands
- Zero behavior change: all 284 proof tests pass unchanged, all handler bodies moved verbatim
- JSDoc with full `@param` tags added to each extracted handler function

## Acceptance Criteria Coverage

- AC1 "`registerProofCommand` is under 150 lines" → Lines 2331–2425 = 95 lines. ✅ Verified
- AC2 "8 non-exported handler functions exist" → `handleProofList` (line 647), `handleProofContext` (line 723), `handleProofClose` (line 762), `handleProofPromote` (line 1012), `handleProofStrengthen` (line 1341), `handleProofAudit` (line 1600), `handleProofHealth` (line 2148), `handleProofStale` (line 2216). ✅ Verified
- AC3 "Each subcommand handler receives `parentJson: boolean`; root handler does not" → All 7 subcommand handlers have `parentJson: boolean` as last parameter. `handleProofList` has `(slug, options)` only. ✅ Verified
- AC4 "Zero behavior change — all existing proof tests pass without modification" → 2921 passed, 2 skipped (identical to baseline). ✅ Verified
- AC5 "Two exports unchanged" → `registerProofCommand` and `formatHumanReadable` remain the only exports. ✅ Verified
- AC6 "`pnpm run test -- --run` passes" → All tasks pass. ✅ Verified
- AC7 "Build and lint pass" → Build succeeded, lint has 0 errors (1 pre-existing warning in git-operations.ts). ✅ Verified

## Implementation Decisions

- **JSDoc `@param` tags for options properties.** The spec said "JSDoc on each handler. Brief description + `@param` tags." The project's eslint config enforces `jsdoc/require-param` for destructured options properties. Added `@param options.json`, `@param options.reason`, etc. to satisfy lint. This is consistent with the project's coding standards.
- **Handler placement.** Placed handlers after the module-level helpers (`formatContextResult`, `formatListTable`, etc.) and before `registerProofCommand`, as the spec directed. `formatContextResult` remained at the end of the file (after `registerProofCommand`) since it was already there and the spec didn't call for moving it.

## Deviations from Contract

None — contract followed exactly.

## Test Results

### Baseline (before changes)
```
(cd packages/cli && pnpm vitest run)
 Test Files  124 passed (124)
      Tests  2921 passed | 2 skipped (2923)
   Start at  17:00:12
   Duration  53.05s
```

### After Changes
```
(cd packages/cli && pnpm vitest run)
 Test Files  124 passed (124)
      Tests  2921 passed | 2 skipped (2923)
   Start at  17:04:44
   Duration  46.50s
```

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

### New Tests Written
None — spec explicitly states no new tests for this zero-behavior-change refactor.

## Verification Commands
```
pnpm run build

## Open Issues

- **Pre-existing lint warning in git-operations.ts**: `Unused eslint-disable directive (no problems were reported from 'no-control-regex')` at line 198. Not introduced by this build — pre-existing.
- **`formatContextResult` remains after `registerProofCommand`.** It's the only module-level function placed after the registration function (all other helpers are before). The spec said to place handlers "after the module-level helpers, before `registerProofCommand`" but didn't mention reordering `formatContextResult`. Left as-is to minimize diff and risk.

Verified complete by second pass.
