post(blog): the residual machine idioms out of the shadow post (seven build commits for every outbound message; when the A/B test concludes on 29 October; the ledger only ever gives you two moves; nothing converts to dollars until the price schedule is signed; if your audit log cannot prove you got it wrong it is a hiding place), the filth list in room names, and in both posts the honest rules from the scorecard: the Act's dates, the exclusion as cover removed not a warning, the injection named plainly, observability is a diary and a record the agent did not write is a ledger, fine-tuning moves the average not the tail, what $20 buys from the pricing page, the command contextualised
This is a live, recomputable drift receipt — the on-chip proof of where this commit's work landed (in its authorized domain, out of it, or unplaced), sealed with a signature anyone can verify. It is the same receipt shipped in the on-commit email, hosted here so the claim is checkable on the open web. The full receipt (attestation, density panel, full commit message) publishes at /commit/d51d4cf1f/ shortly after the commit lands.
This is the proven asset: the drift read was produced by a real on-chip walk on sensor: metal, sealed with an ed25519 signature over the canonical body, and bound to the exact lattice by gridHash. Anyone can recompute it and check the signature — no trust in us required.
These are measurements, not a validated risk score. In a pre-registered predictive test the drift metric did not predict real defects (AUC ≈ 0.50, at chance) and the σ is pinned — so nothing here is a probability of loss and nothing here is a price. It is honest telemetry we publish while the instrument is under calibration.
