The fence-advance is itself fenced against an older acquisition: a per-locator acquisition token minted by the lock authority at every lock grant, carried unchanged across the acquisition's brain operations and swap-loop retries, compared and recorded by the brain store atomically with every brain mutation (advance included). A superseded acquisition's delayed advance is refused, mints nothing, and yields no usable fence (mandatory abort-release-surface, expected on deadline supersession). The 'refused unconditionally' claim is precisified to the exact linearization boundary; the pre-step-1 interruption predicates are restated over exact content/database state, expressly permitting the advance's epoch/token change (F18). New §7.10 stale-advance refusal and pre-advance linearization controls; token invariants added to the fence static controls (§7.10, §7.16); §8 item 16 and preamble extended.
