+"""
+Normalize gate artifact JSON schema — minimal `agent` field fix.
+
+History: F-123..F-135 (13 features x 3 gate files = 39 files) were closed
+with the wrong field name (`reviewer` instead of `agent`). `verify.sh`
+rejects those files because it checks `obj.get('agent') == '<role>'`.
+
+This script is idempotent: it adds `agent` from the legacy `reviewer`
+field (when present and matching) without touching any other field.
+Re-running it on an already-normalized file is a no-op. `stage` is not
+required by `verify.sh`, so we leave it alone.
+
+Usage:
+  python3 scripts/fix_gate_schema.py                 # all artifacts
+  python3 scripts/fix_gate_schema.py F-123 F-124     # specific features
+  python3 scripts/fix_gate_schema.py --dry-run       # preview only
