I'll start by reading the mandatory context files before doing anything else.

This is DGR-001. The recent commits ("compare safetensors and gguf", "deterministic CPU/GPU benchmark runner", "live benchmark") suggest work may already be substantially done. Let me check progress, prd.json, and existing evidence.

Substantial work exists. Let me examine the existing evidence and benchmark code to verify against acceptance criteria.

Let me examine the implementation module and tests.

I now understand the state well. Let me check the working-tree diffs I must preserve, run the current tests, and check the full suite baseline.

Targeted tests pass and DGR-002's working-tree changes are isolated. Now I'll assess against the acceptance criteria. The contract is solid but has genuine gaps I should close before marking done:
 
1. **AC1** requires the same *prompts, context lengths, output lengths, sampling policy* — these aren't encoded in the versioned contract, so "same across recipes" isn't locked.
2. **AC2** requires explicitly *separating correctness/quality lanes from performance/fit lanes* — currently only an implicit `output_drift`, no explicit quality policy stating BF16≠Q2_K.
3. **AC5** — the gate thresholds (`1.10` speedup, `0.5` artifact ratio) are hardcoded in code, not in the versioned JSON that DGR-014 must consume without changing thresholds.
 
I'll close these three. Let me strengthen the contract module.
