…ashcore-dev-961 Two conflicts, both about the rust-dashcore pin, plus one semantic break the textual merge hid. `v4.2-dev` pinned `a97b32c6` in #4455, which turns out to be a side branch off the old `173ffac0` carrying cherry-picks of the seed refresh and the BIP-39 fix. This branch pinned `5877d15f`, on `dev`'s mainline. Neither contains the other. Resolved onto `dev`'s head `b66db390`, which is a superset of both: it carries the seed refresh (#970) and the BIP-39 fix (#980) that `v4.2-dev` wanted, plus #966 and #969 that this branch needs, plus the QRInfo masternode-sync recovery (#947). The hidden break: `v4.2-dev` added `get_wallet_blocking`, which calls `blocking_read()` on the wallets map — a method this branch removed when the map became an `ArcSwap`. Git merged the file cleanly and the build failed. The accessor now loads wait-free; its name is kept so the FFI callers that predate the change still compile.

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).
