Commit 7fde4d782
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/7fde4d782/ 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.
Δ weighted bleed · Δ-spread max king-move leak · Γ traction slope · 𝒱 reef volatility · Θ efficiency decay (null → pending; no per-commit token meter). Definitions are carried in the signed signal's notes.
Sufficient for: where it landed, re-runnable from the commit: same bytes, same hash. NOT sufficient for: whether the work was good, which is undecidable (Rice, 1953); nothing here claims it.
