Per the decision on the blocker: the pinned branch is re-cut without #866's `rescan_committed_range`. Two reasons, and the second is the one that decides it. The Codex finding stands — the sweep accumulates every match from the birth height into one `BTreeMap` and queues them together, so an eclipsing compact-filter peer can turn a full-history rescan into a chain-length allocation followed by millions of block requests, and nothing upstream bounds it yet. More decisive is the honest case. On a real long-history CoinJoined restore the #846 backward sweep ran 191 times, reached a 2.9 GB footprint, and was killed by jetsam before finishing; the coalescing fix for that is dashpay/rust-dashcore#974, which is not merged. Shipping #866 without #974 would trade a mid-sync stall for a restore that kills the app — and long-history migrated wallets are exactly this release's audience. What the pin still carries is the point of this PR: #964, #960, #955, #947 and #946, the six sync-stall fixes, plus #945, #928, #963, #965, #967, #970 and #980. Dropping #866 restores the status quo of the previous pin rather than introducing a regression — #846's mid-sync invisibility was never fixed in what shipped — and the migrated-wallet heal (#4377) does a full rescan, so it does not lean on this sweep. #866 and #974 come back together next cycle, with a bounded drain for the accumulation finding. Branch: dashpay/rust-dashcore@chore/sync-fixes-without-swept, re-cut at 33030acf (base #945 plus eight cherry-picks, #866 omitted).
