<objective> Investigate what went wrong during a GSD workflow execution. Analyzes git history, .planning/ artifacts, and file system state to detect anomalies and generate a structured diagnostic report.
Purpose: Diagnose failed or stuck workflows so the user can understand root cause and take corrective action. Output: Forensic report saved to .planning/forensics/, presented inline, with optional issue creation. </objective>

<context> Data sources:
git log(recent commits, patterns, time gaps)git status/git diff(uncommitted work, conflicts).planning/STATE.md(current position, session history).planning/ROADMAP.md(phase scope and progress).planning/phases/*/(PLAN.md, SUMMARY.md, VERIFICATION.md, CONTEXT.md).planning/reports/SESSION_REPORT.md(last session outcomes)

<process> Execute end-to-end. </process>
<success_criteria>
- Evidence gathered from all available data sources
- At least 4 anomaly types checked (stuck loop, missing artifacts, abandoned work, crash/interruption)
- Structured forensic report written to
.planning/forensics/report-{timestamp}.md - Report presented inline with findings, anomalies, and recommendations
- Interactive investigation offered for deeper analysis
- GitHub issue creation offered if actionable findings exist
</success_criteria>
<critical_rules>
- Read-only investigation: Do not modify project source files during forensics. Only write the forensic report and update STATE.md session tracking.
- Redact sensitive data: Strip absolute paths, API keys, tokens from reports and issues.
- Ground findings in evidence: Every anomaly must cite specific commits, files, or state data.
- No speculation without evidence: If data is insufficient, say so — do not fabricate root causes.
