That was the original +//! placement and it is falsified: `commits.md` is path-scoped by its frontmatter +//! to `CHANGELOG.md`, `release-plz.toml` and `Cargo.toml`, while the hook fires +//! on every commit in every session, most of which touch none of those three. A +//! record absent at the moment it is needed is indistinguishable from one that +//! was never written.

Presence: the always-loaded file still +//! names `identity_deny` as the authority over a harness identity request, still +//! points the signature half at its own issue rather than absorbing it, and +//! still routes to the detail. That catches deletion and drift — the failure +//! mode for a rule whose whole value is being readable at Stop time. +//! +//! It does not catch a session that reads the line and complies anyway. The +//! runnable half of that is `no-denied-identity-prescribed`, which refuses the +//! prescription in the tree, and `identity_deny` itself, which refuses the +//! commit.
