Add detectCheckpoint(), resumeFromCheckpoint(), and clearCheckpoint() to lib/state.cjs for pipeline resume detection at mgw:run startup. - detectCheckpoint(issueNumber): checks if active state file has a checkpoint with pipeline_step beyond "triage", returns checkpoint data if resumable - resumeFromCheckpoint(issueNumber): returns checkpoint data plus computed resumeStage based on resume.action mapping - clearCheckpoint(issueNumber): resets checkpoint to null for fresh-start scenarios Closes #237 (partial) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add checkpoint detection logic to the validate_and_load step in commands/run/triage.md. When a prior pipeline run left a checkpoint with progress beyond triage, the pipeline now: 1. Detects the checkpoint via detectCheckpoint() 2. Displays checkpoint state (step, completed work, artifacts) 3. Offers Resume/Fresh/Skip options via AskUserQuestion 4. Resume: loads checkpoint context and jumps to appropriate stage 5. Fresh: clears checkpoint via clearCheckpoint() and starts over 6. Skip: exits pipeline for this issue This enables recovery from interrupted sessions, context switches, and multi-session pipeline execution without losing prior work. Closes #237 (partial) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add comprehensive documentation for the checkpoint resume system: - Resume detection functions (detectCheckpoint, resumeFromCheckpoint, clearCheckpoint) with signatures and return types - Resume action to pipeline stage mapping table - Resume detection flow diagram - Pipeline step order constant documentation - Resume context shapes per action type - Updated consumers table with checkpoint resume entry Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
