The security layer model moved v0.1 -> v0.4 (accepted) after ops-warden's
assent. Both §5 asks from ADR-0010 were adopted: §5.2 now sanctions the conduit
shape on the supplied-authority property, and §5.3 is the declared engine gap
amendment, carrying the four fields verbatim and crediting ops-warden's
delegation machinery as prior art.
Which creates an obligation. §5.3 requires those fields MACHINE-READABLY, and
§11 makes "every direct Tooling client maps to a declared §5.1/§5.2/§5.3 entry"
a mechanical check. ops-warden's declaration was prose in INTENT.md — the repo
that proposed the shape was not implementing it.
layer.yaml is the map: 5 contacts (2 declared gaps, 1 read-only observation,
2 conduits) plus the non-Tooling clients recorded explicitly so the check is
total rather than silently selective.
scripts/check_layer_conformance.py enforces it and found three undeclared
modules on its first run — all false positives (help text, a docstring, and the
doubles library that SIMULATES bao rather than calling it), which is why the
scan now matches invocation shapes instead of the word: an httpx call built
against the configured OpenBao address, or an argv whose first element is the
bao binary.
tests/test_layer_conformance.py adds the §5.2 test the standard says SHOULD
exist: _caller_env() returns the caller's environment unchanged, and proxy.py
is asserted not to reference X-Vault-Token, approle login, or token create — a
conduit that presents its own token is not a conduit.
No assertion on review dates, deliberately: a date-triggered failure breaks the
build on a calendar day with no code change, the same reasoning WP-0033-T05
recorded for blocker staleness.
398 tests pass, ruff clean.
