Overview

Predicate: a proposal may only target a ‘canon` zone (ADR 0035). Runs on the `accept` floor, where Evaluation#target is the proposal’s resolved target_key. Refuses promotion into workspace/derived/ quarantine/queue — the queue→canon path is the only coherent one. No bespoke #error; failures accumulate into GuardFailed (ADR 0031).
