Each red action is something the assigned job does not include — e.g. an agent told only to write and edit documentation that instead edited documentation.

How this was detected — no language model was involved. Every action was checked by per-step membership: the action's (kind × target) compared against the set the assigned role permits — a bitmask comparison. No language model judged what counts as drift; the thing checking the AI is not another AI.

What rail this is. This is the semantic rail — the check run in software. No hardware performance counter was read; no number here is a hardware measurement. The physical-PMU rail — the identical check read off the processor's own cache counters — is the production upgrade; the mechanism is the same, only the rail differs.

Verify it. This receipt was generated from the real trace above. Re-run npm run pmu-demo to reproduce it from the recorded session. Companion receipt lattice-movie.html is the controlled run — a known out-of-role action injected and caught.
