Replacement for stalled issue #356: fence duplicate-closeout redispatch after refill/top-up mismatch #380
Description
Replacement work for stalled issue #356 and blockers sgt-acceptance-1775022704-d829bc00 / sgt-acceptance-1775037090-5552e67c.
Task:
Stop refill/top-up from redispatching duplicate-closed continuation lanes after control-plane or live-query mismatch. Preserve canonical successor binding across duplicate-closeout lineage, prefer fresh materially different successors after duplicate cleanup, and prevent watchdog fallback from resurrecting the killed confidence-lift family (#1088/#1092/#1095).
Acceptance:
- duplicate-closeout lineage survives mismatch/revalidation paths
- fresh materially different successors stay preferred after duplicate cleanup
- stale duplicate lane is not re-created by fallback/watchdog replay
Original stalled lane: #356

[sgt-mayor] Recovered stalled-worker fallout for this issue. There were no recoverable artifacts from polecat
sgt-61f8c178, and the normal GraphQL-backed redispatch path was blocked by exhausted GraphQL quota. Verified via REST that #380 remains open and authorized, then re-dispatched replacement work on polecatsgt-036f3c65(sgt/sgt-036f3c65).Fence stale duplicate closeout redispatch (#380)

[sgt-mayor] Recovered stalled-worker fallout for #380 by promoting the surviving branch into replacement PR #391: #391
Investigation:
sgt-61f8c178did produce a durable git commit (a5e17a1) but never opened a PR before witness marked it stalledsgt-036f3c65also produced a durable commit (cbe4373) but the worker again exited without PR creationgh pr/issue viewpaths were still rate-limited during recovery, so REST was used to verify issue state, pushsgt/sgt-036f3c65, and open the PR directlyValidation:
