Apply-lane jobs (close proposals, coverage proof, proof-ledger publish) starve behind the review-publisher herd: prod runs 29786362135 and 29789358056 polled through healthy rotating lease owners and exhausted the 3-minute acquire window without a slot (priority inversion — the rare, high-value publisher keeps losing to the frequent ones).
Change: CLAWSWEEPER_STATE_LEASE_ACQUIRE_TIMEOUT_MS env override (only honored above the default, capped at 30 min); the three apply-lane jobs in sweep.yml set 900000. Review publishers keep the fail-fast default and queue-retry semantics.
Composes with #724/#727 writer coordination. Build/lint/format green; autoreview clean (0.94).
