On-chip drift receipt

blog(insurability): the receipt is the fiduciary duty — undecidability → uninsurable → zero-latency

2026-07-06 · a30cb6cff

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/a30cb6cff/ shortly after the commit lands.

✅ DECIDABLE: WHERE this work landed is provable and re-runnable — recompute it yourself. WHETHER it is bug-free is UNDECIDABLE (Rice); we do not claim that.LANE: IN

Silicon-Attested Provenance

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.

Drift Telemetry (experimental — under calibration)

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.
