 ## Harness portability
 The **atoms** above are multi-model by construction. The **harness** — the orchestration layer that executes backlog issues (builder sessions), verifies them (cold readers, locate-tests) and files PRs — ran its first full loop on Claude (erp#38 → PR erp#62, 2026-07-15). **Operator direction (2026-07-15): that layer must not have Anthropic as a hard dependency either — the same loop should run on Mistral, or on hermes + Ornith / MLX-served local models.**
 The protocol was built for this: everything an executing agent needs lives in **files and issues** — AGENTS.md orientation, per-issue Execution footers (first command, done-means), acceptance tests defined in the issue itself, deterministic validators around every output. Nothing load-bearing lives in a vendor's context window. Any runtime that can read the forge and run a shell can attempt an issue; the acceptance gates don't care who built the thing.
 Migration ladder (evidence-gated like everything else — erp#63):
 1. **Verifier roles first** — locate-tests, cold-reader audits, refutation passes: bounded, read-only, cheap. Re-run the already-passed erp#38 locate-test on **Ornith** (hermes, `127.0.0.1:18080`) and on an **MLX-served candidate** (Qwen3 14B/30B-A3B, Mistral Small 3.x class); require verdict parity with the Claude run. Once parity holds, **prefer cross-family verification**: a different model family refuting the builder is stronger evidence than the builder's family agreeing with itself.
 2. **Scoped builders benched** — one small, tightly-footered issue (a #56-class fix) attempted end-to-end by a Mistral-driven runtime against the unchanged acceptance gates; measure completion rate and intervention count.
 3. **Claude stays the default** for multi-file builders, ambiguity and fiscal reasoning **until the bench says otherwise** — a routing-policy fact (complexity ceiling above), not an allegiance.
