Name the accepted v0.7 text in force and converge the A12 detector (GH-DEC-2026-021).

ValidatedAgainst named the proposed v0.8, which is held under GH-DEC-2026-019,
so every run claimed a check against text that does not govern. It now names
security-layer-model_v0.7.md (net-kingdom@66dc491) as amended by
GH-DEC-2026-017, -020 and -021 (gate-house@39d9287), per 021 §2.

The pin detector converges on ops-warden's reference (021 §3): keys naming a
standard or companion version, versions in path or file-name tokens, and the
021 addition of any version token in a standard:/companion: value. A revision
cited in prose is provenance and is no longer reached (021 §1), including
under standard_*-prefixed keys that name no version. One kept difference: an
empty version key carries no version and is not flagged.

Survey receipt refreshed; no declaration in the estate carries a pin.
