# Edge Payload Schema Audit

Use this skill when the next graph question is no longer "can richer edge
semantics exist?" but "what exact sidecar schema can the current low-control
graph honestly support right now?"

## Purpose

- read the bounded low-control owner graph plus the current TopoNetX and
  Clifford audits
- derive one minimal read-only sidecar schema for admitted edge relations
- separate:
  - required carrier fields
  - optional scalar carriers
  - deferred GA fields
  - forbidden scope
- keep the schema proposal repo-held and nonoperative

## Execute Now

1. Load:
   - `system_v4/a2_state/graphs/a2_low_control_graph_v1.json`
   - `system_v4/a2_state/audit_logs/TOPONETX_PROJECTION_ADAPTER_AUDIT__CURRENT__v1.json`
   - `system_v4/a2_state/audit_logs/CLIFFORD_EDGE_SEMANTICS_AUDIT__CURRENT__v1.json`
2. Keep the canonical graph store unchanged.
3. Emit one JSON report, one markdown note, and one compact packet under `system_v4/a2_state/audit_logs/`.

## Quality Gates

- Do not change canonical graph edges or attributes from this slice.
- Do not include `OVERLAPS` in the admitted schema scope.
- Do not include `SKILL` edges in the admitted schema scope.
- Keep the result audit-only, proposal-only, and repo-held.
