This guard was a bare `if` with no else until 2026-07-24 — when the daemon was down the release build simply ran uncached, and the deficit's frequency was zero by construction, so it never ranked for fixing (shell→dag census §4.I lists it as an absorbing fallback). It is NOT yet a refusal: STEP 2 of the srvN build-cache design flips this to fail-closed, and that flip is operator-sequenced AFTER a live T4 read-back proves P1b provisioning converges on srv1/srv2/srv4 — refusing before then would red the whole fleet, which is why the interim is loudness rather than a wall. The receipt line names the host, so a single misconfigured runner is attributable rather than fleet-wide noise."
