The mental model says the brief's surface chapters carry an `## Acceptance` block in Given-When-Then format; the identity chapter has no such block and names an issue as its acceptance corpus instead.

A premise contradiction (severity minor) found by the cross-document consistency pass.
- End A:
.abcd/development/brief/01-product/03-mental-model.md:85— "The brief's press release and surface chapters carry an## Acceptanceblock in the same format." - End B:
.abcd/development/brief/04-surfaces/19-identity.md:124— "Its acceptance corpus is"
03-mental-model says the brief's press release and surface chapters carry an ## Acceptance block in the same Given-When-Then format, as part of the uniform acceptance discipline the intent-auditor compares reality against. 19-identity has no ## Acceptance section. Its sections run from Sub-verbs to References, and its only statement of acceptance is a sentence naming iss-143 as its acceptance corpus. None of the twelve surface chapters in this set carries the block either, so the mental model's claim does not hold for them.
Evidence: .abcd/work/reviews/2026-10-26-consistency/00-summary.md, finding 63.

- iss-143tagline three-variant drift: the repo runs three different self-descriptions — README strapline (an opinionated, intent-driven development framework for product thinkers), plugin.json description (host-agnostic configuration layer for development ... usable as a plugin in compatible agent harnesses), and AGENTS.md (a host-agnostic configuration layer for development). The drift is itself the finding: one-canonical-primitive wants a single recorded tagline (a DECISIONS.md line, or the brief's product chapter as the home) with per-surface renderings derived from it. Adopting any new wording without that consolidation just mints a fourth variant. Surfaced by the 2026-07-27 tagline assessment. Detector: a positioning-currency check that the three surfaces render from one recorded home.
