post(blog): a-named-lever-is-a-handhold round 6 — the readability pass in the operator's speaking voice and the declaration of terms: no apology, the foundation is done and the ticket is bought, the three rooms named (the actuary, the allocator, the compliance officer), the clean-hands ego burned as a bypass, one metric (a signature from the other class), objects without opinions, the reflexive tics gone, the close as the two futures and "I do not need you to believe me"
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/b381f8c0e/ 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.
