Review layer model v0.6; publish the PEP stance map §6.4 requires

All three v0.4 findings were acted on — §9.1 split into pending/declared-gap and
§5's scope rule adopted as recommended and credited, and §9.6 ruled via the
load-bearing/attributive distinction with ops-warden's `# audit must not block
signing` named as the estate's live example.

Checked the favourable ruling rather than accepting it. §9.6's test is "no
control branches on its presence": the only consumer of audit.jsonl is `warden
activity`, which displays. Nothing gates on a signing record, so the lane is
genuinely attributive. AuditTrail.md now records the ruling instead of the open
question, and states that the trade must be revisited if a control ever gates on
the trail.

CONFORMANCE ACTION. §6.4 obligation 3 requires a stance map "published rather
than held in code", and requires every PEP-shaped consumer to publish one so the
maps can be inventoried — naming ADR-0009 as the reference shape. ops-warden was
not doing it: the map lived in PolicyConfig.failure_modes, a dataclass default.
Not a code comment, but not published either.

pep-stance.yaml publishes it, and the test asserts the published map EQUALS the
shipped default. A published map that may drift from the code is worse than no
map, because it invites reliance it cannot support.

Two findings sent to gate-house, in history/2026-08-29-layer-model-v06-review.md:
§6.4 obligation 1 (no side effect without a decision record) contradicts
obligation 3 and §9.3, with ops-warden's blessed fail-open stance as the
instance; and §6.4 mandates a stance-map inventory in §13 that §13 does not
implement — where ops-warden is currently the only PEP to have published one.

402 tests pass, ruff clean.
