Report Verification — Reverse Engineering Phase 4 Critic

Verify the consolidated As-Is specification produced by re-generate-report against the Phase 1-3 source artifacts. Runs as an independent Critic in a separate agent context.

Three Principles (Critic Perspective)

1. Code is Truth

• Phase 1-3 artifacts are the sole authority. If the report states something not present in the artifacts, the report is wrong.

2. Traceability to Line

• Every requirement in the traceability matrix must trace back to a Phase 3 document and ultimately to source code. Broken chains are failures.

3. Behavior over Intent

• Verify what the report claims against what the artifacts show. Do not interpret or justify discrepancies.

Execution

Step 1: Load Artifacts

Read docs/reverse/{analysis}/manifest.json.

Verify phase4.status is "completed" — if not, report error and stop.

Load:

• Report: docs/reverse/{analysis}/04-report.md
• Structure map: docs/reverse/{analysis}/01-structure-map.md
• All logic diagrams: docs/reverse/{analysis}/02-logic-*.md
• All requirements: docs/reverse/{analysis}/03-requirements-*.md

Step 2: Completeness Verification

Check that the report includes all artifacts:

Module coverage:

• Count components in structure map
• Count components in report's module catalog
• Flag missing components

Requirements coverage:

• Count requirements across all Phase 3 documents
• Count requirements in report's requirements catalog
• Flag missing or extra requirements

Logic diagram coverage:

• Count logic diagrams in Phase 2
• Count diagrams referenced in report's appendix
• Flag missing diagrams

Step 3: Traceability Matrix Verification

For each entry in the traceability matrix:

1. Verify the REQ-ID exists in the corresponding Phase 3 document
2. Verify the source file:line matches between report and Phase 3 document
3. Verify the EARS type classification matches
4. Flag discrepancies

Step 4: Cross-Reference Consistency

Check internal consistency of the report:

• Components in executive summary match module catalog
• Requirement counts in summary match actual count in catalog
• EARS type distribution table is arithmetically correct
• Question list items trace to Phase 1-3 question lists

Step 5: Factual Accuracy Spot Check

Select 5 requirements at random from the report. For each:

1. Trace back to the Phase 3 document
2. Trace back to the source code
3. Verify the chain is unbroken and accurate

Step 6: Generate Verification Report

Write to docs/reverse/{analysis}/verification/v4-report.md:

# Report Verification: {analysis}

**Verification Date**: {YYYY-MM-DD}
**Target Document**: 04-report.md
**Verdict**: {PASS / WARN / FAIL}

## Summary

| Check | Result | Details |
|:------|:-------|:--------|
| Module Completeness | {✅/⚠️/❌} | {in_report}/{in_source} components ({%}) |
| Requirements Completeness | {✅/⚠️/❌} | {in_report}/{in_phase3} requirements ({%}) |
| Logic Diagram Coverage | {✅/⚠️/❌} | {in_report}/{in_phase2} diagrams ({%}) |
| Traceability Matrix | {✅/⚠️/❌} | {valid}/{total} entries ({%}) |
| Internal Consistency | {✅/⚠️/❌} | {issues} inconsistencies |
| Spot Check Accuracy | {✅/⚠️/❌} | {accurate}/{checked} samples |

## Verdict

{PASS/WARN/FAIL}: {explanation}

## Details

### Missing Modules
| Component | Present In | Missing From |
|:----------|:-----------|:-------------|

### Missing Requirements
| REQ-ID | Phase 3 Document | Issue |
|:-------|:-----------------|:------|

### Traceability Issues
| REQ-ID | Issue | Report Says | Source Says |
|:-------|:------|:------------|:------------|

### Internal Consistency Issues
- {description}

### Spot Check Results
| # | REQ-ID | Report → Phase 3 | Phase 3 → Source | Verdict |
|:--|:-------|:------------------|:-----------------|:--------|

## Recommendations

1. **[{severity}]** {fix description}

Step 7: Update Manifest

• Set phase4.verification to "verification/v4-report.md"
• If verdict is PASS or WARN: set phase4.status to "verified"
• If verdict is FAIL: leave phase4.status as "completed"
• Update updated timestamp

Verdict Criteria

Any single FAIL criterion results in overall FAIL.

Prohibited Actions

• Do NOT modify the report document
• Do NOT modify Phase 1-3 artifacts
• Do NOT approve documents with FAIL status
• Do NOT access the Doer's conversation context
