Source Fix Remediation Workflow

• Delete synthetic artifact generation used to pass gates.
• Replace free-text inference with structured decision requirements.
• Convert unknown/ambiguous paths to explicit failures.

6. Preserve observability

• Add explicit error logs and validation messages with actionable detail.
• Persist reasons in status metadata for postmortem/debug.

7. Validate end-to-end

• Run targeted integration tests first, then marker suite.
• Re-run affected eval slice.
• Confirm invalid paths now fail; valid paths still pass.

8. Clean bad generated data

• Remove previously persisted invalid eval rows/artifacts derived from fallback paths.
• Keep only rows generated from valid upstream outputs.

Editing checklist

• No fabricated benchmark_plan.md / engineering_plan.md / todo.md / YAML for recovery.
• No "contains APPROVED" style routing.
• No unknown-agent remap fallbacks.
• No silent default session context for runtime flows.
• Status transitions only happen after explicit validation success.
