Re Generate Report

Integrated Report — Reverse Engineering Phase 4

Aggregate ALL reverse engineering artifacts from Phase 1-3 into a consolidated As-Is specification document. This skill reads the manifest to discover all artifacts and produces a single comprehensive report.

Three Principles

1. Code is Truth

• As-Is spec documents ACTUAL code behavior
• Suspected bugs remain in Question List, not removed from spec
• No editorial improvements or "should" statements

2. Traceability to Line

• Traceability matrix links every requirement to source line
• All findings traceable to Phase 1-3 artifacts
• Orphaned findings (no source) flagged for review

3. Behavior over Intent

• Executive summary focuses on "what" system does, not "why"
• Architectural patterns described from observed structure
• No assumptions about business intent

Execution

Step 1: Load Manifest and Collect Artifacts

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

Verify:

• phase3.status is "verified" — if not, report error and stop

Collect all artifacts:

• Phase 1: phase1.output → structure map
• Phase 2: phase2.completed[].output → logic diagrams
• Phase 3: phase3.completed[].output → requirements documents

Read each artifact and extract key sections.

Set phase4.status to "in_progress".

Step 2: Cross-Reference Verification

Requirements → Logic Diagrams: For each requirement, find corresponding nodes in Phase 2 logic diagrams. Confirm line numbers match.

Logic Diagrams → Structure Map: For each logic diagram, confirm the source file is listed in the Phase 1 structure map.

Log inconsistencies:

Step 3: Build Traceability Matrix

Combine requirements from all Phase 3 documents:

Evidence strength:

• ✅ Strong: Implementation + verified by Critic
• ⚠️ Medium: Implementation + partial verification
• ❌ Weak: Implementation only

Step 4: Consolidate Question Lists

Merge from all phases and prioritize:

• 🔴 Critical: Suspected bugs with high impact (data loss, crashes)
• 🟡 Important: Architecture/design clarity questions
• 🟢 Informational: Optimization opportunities, style concerns

Step 5: Generate Executive Summary

Summarize from collected artifacts:

• System type and technology stack
• Primary functions (from structure map)
• Analysis scope and coverage
• Key findings and technical debt count

Step 6: Generate Report

Write to docs/reverse/{analysis}/04-report.md:

**Document Version**: 1.0
**Analysis Date**: {YYYY-MM-DD}

Step 7: Update Manifest

• Set phase4.status to "completed"
• Set phase4.output to "04-report.md"
• Update updated timestamp

Validation Before Completion

After writing the report, re-read it and verify every number against the source data. Counting errors in the executive summary undermine confidence in the entire report.

• All Phase 1-3 artifacts collected and referenced
• Cross-reference verification completed
• Traceability matrix links all requirements to source
• Question list prioritized (Critical / Important / Informational)
• Count verification: Total requirements in executive summary matches actual count in requirements catalog. EARS type distribution sums to the total. Question list count matches actual items in Appendix C. Re-count by enumerating each item — do not rely on numbers from Phase 3 documents or your own earlier statements
• Executive summary reflects actual findings (no speculation)
• No requirements added that aren't in Phase 3 documents
• manifest.json updated

Prohibited Actions

• Do NOT add requirements not present in Phase 3 artifacts
• Do NOT editorialize or propose improvements in As-Is spec
• Do NOT remove suspected bugs — they belong in the Question List
• Do NOT speculate on business intent
• Do NOT modify Phase 1-3 artifacts
