post(blog): the math as the pipeline runs it, and the two-way optimisation that shows the side — the commit as the cost unit with tokens/minutes/calls that refuse to add (KR40 U-1), medians 40,079 tokens / 5.33 min / 12 calls over 621 commits, the price table pinned 2026-09-17 to BLS May 2025 wages and the vendors' published rates (the no-arbitrage step), yield = passes ÷ decidable commits currently 0 on every lane so every per-pass floor prints UNMEASURED with its reason, σ = the top cell's margin over the board in SDs with the shuffled-label null as the zero, and the two-way part: the deployer lowers a swing-priced premium by lowering the measured swing, the carrier lowers its loss ratio on the same swing, the licence is fixed at $20 in either direction — nothing on the seller's side is paid for the drift or for hiding it (both posts)
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/125fee700/ 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.
