harness-doctor — Harness Structure Diagnosis + Prescription

"A good harness gets simpler over time. If it's getting more complex, something is wrong."

Diagnoses harness structural health across 5 layers and proposes M/S/R prescriptions:

1. L1 Structural completeness — required file existence (CLAUDE.md · .claudeignore · .claude/)
2. L2 Complexity — current state vs. simplification principle (line count · unused files · duplicate definitions)
3. L3 Drift — rule vs. actual pattern mismatch (broken references · stale files · conflicting rules)
4. L4 Connection diagnosis (FH environment only) — meta hub ↔ field project reference consistency
5. L5 Pattern analysis (FH environment only) — skill activity · call context appropriateness · effect metrics

Execution Steps

Step 1. Confirm Diagnostic Target

Check current cwd harness file structure and determine if FH environment (tracks/ + knowledge/ + plugins/ all present).
