7<objective>
8Investigate 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.
9
10Purpose: Diagnose failed or stuck workflows so the user can understand root cause and take corrective action.
11Output: Forensic report saved to `.planning/forensics/`, presented inline, with optional issue creation.

35<success_criteria>
36- Evidence gathered from all available data sources
37- At least 4 anomaly types checked (stuck loop, missing artifacts, abandoned work, crash/interruption)
38- Structured forensic report written to `.planning/forensics/report-{timestamp}.md`
39- Report presented inline with findings, anomalies, and recommendations
40- Interactive investigation offered for deeper analysis
41- GitHub issue creation offered if actionable findings exist
42</success_criteria>
43
44<critical_rules>
45- **Read-only investigation:** Do not modify project source files during forensics. Only write the forensic report and update STATE.md session tracking.
46- **Redact sensitive data:** Strip absolute paths, API keys, tokens from reports and issues.
47- **Ground findings in evidence:** Every anomaly must cite specific commits, files, or state data.
48- **No speculation without evidence:** If data is insufficient, say so — do not fabricate root causes.
