The mental model calls the itd-60 doc-fidelity loop planned and not yet exercised; the docs chapter describes the itd-60 doc-fidelity gate as a working gate in the present tense.

A premise contradiction (severity minor) found by the cross-document consistency pass.

• End A: .abcd/development/brief/01-product/03-mental-model.md:79 — "This work is governed by the planned itd-60/itd-61 doc-fidelity + derivation loop — itd-62 would be that loop's first real exercise."
• End B: .abcd/development/brief/04-surfaces/10-docs.md:66 — "The doc-fidelity gate (itd-60) judges whether the brief describes every surface that ships."

03-mental-model says the framework-provided discipline is governed by 'the planned itd-60/itd-61 doc-fidelity + derivation loop', and that itd-62 'would be that loop's first real exercise'. 10-docs describes the itd-60 doc-fidelity gate in the present tense: it judges whether the brief describes every surface that ships, and it refuses spec closes and release cuts. The doc-fidelity half cannot be both planned and never exercised and also a gate that runs today.
