# Delegation Evidence: 101 Focused Lane Harness Projection

## Providers Used
- Claude: adapter feasibility lane failed on monthly spend limit; accepted only
  as failure-mode evidence.
- Codex: failure/fallback design, implementation seam checks, projection
  critic, and targeted model-contract verifier.
- Grok: thinness/release-risk critics and targeted model-contract sanity check.
- Antigravity: adapter feasibility fallback during shaping.

## Key Receipts
- `2f17cadc-aa7c-42da-adec-78d30e17fa1f` - Claude failure evidence; rejected as
  successful work, accepted as provider-failure proof.
- `db512cc0-9ba8-4158-9cf9-5892c18920ad` - Codex fallback taxonomy lane;
  accepted for `record_and_return` / `lead_explicit` semantics.
- `68900612-ff21-4280-bcfb-6df7e81ce412` - Grok post-implementation thinness
  critic; accepted, no overbuild blocker.
- `4e458e39-d9bc-4544-ac34-060ccc1532c8` - Codex post-implementation
  projection critic; rejected until blockers were fixed.
- `660f4414-f54f-47e1-9bec-78abd2696760` - Codex fresh verifier; found the
  off-roster model override blocker.
- `bce0737e-54c9-4cd2-b715-69319e7abc7d` - Grok fresh verifier; passed but was
  outweighed by the Codex blocker.
- `94d8b1b8-6d8b-4eaa-b848-1a77d19056a2` - Codex targeted model-contract
  verifier; passed after fix.
- `b338c427-bd22-4747-b48d-c67349e8bb82` - Grok targeted model-contract
  verifier; passed after fix.
