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superseded acquisition's delayed advance is refused, mints nothing,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.
