itd-16 makes /abcd:audit an open umbrella a schema or prompt-quality audit can join; 16-lint reserves it for hash-chain fidelity and calls a check of form a lint.

itd-16 makes /abcd:audit an open umbrella a schema or prompt-quality audit can join; 16-lint reserves it for hash-chain fidelity and calls a check of form a lint.

A terminology drift (severity nitpick) found by the cross-document consistency pass.

• End A: .abcd/development/intents/drafts/itd-16-hash-chain-merkle-audit.md:65 — "schema audit, prompt-quality audit, third-party-vendor audit"
• End B: .abcd/development/brief/04-surfaces/16-lint.md:20 — "/abcd:audit stays reserved for itd-16's hash-chain fidelity surface."

itd-16 names schema audit, prompt-quality audit and third-party-vendor audit as applications that may register as their own intents under the /abcd:audit umbrella. 16-lint says a verb applying rules about form is, in adr-40's vocabulary, a lint, and that /abcd:audit stays reserved for itd-16's hash-chain fidelity surface. A schema check is an audit sub-verb in one document and a lint in the other.
