Reconcile inputs when abandoning a descendant.
If a descendant spent another wallet coin alongside the orphaned reward, AddToSpends removed that coin from setWalletUTXO. Line 1103 abandons the descendant, but MarkInputsDirty does not restore the coin. Call ReconcileWalletUTXOs(desc_tx->tx, batch) after the state change. Notify observers for changed descendants as RecursiveUpdateTxState does; the later notification covers only the coinbase.

Fixed: ReconcileWalletUTXOs() is now called for each abandoned descendant, same as RecursiveUpdateTxState() does. Dash-specific, because setWalletUTXO does not exist upstream.

@knst, thanks for the clarification. The supplied code now calls ReconcileWalletUTXOs(desc_tx->tx, batch) for each abandoned descendant. This addresses the setWalletUTXO concern.
One part remains: the loop does not notify observers when a descendant changes state. The later NotifyTransactionChanged call covers only the coinbase. Add a CT_UPDATED notification for each changed descendant, as RecursiveUpdateTxState() does.

Learning: In Dash's C++ wallet implementation in src/wallet/wallet.cpp, setWalletUTXO is Dash-specific and does not exist upstream in Bitcoin Core. When abandoning transactions, CWallet::ReconcileWalletUTXOs restores eligible wallet inputs to setWalletUTXO; CWallet::MarkInputsDirty alone does not restore them.

Preliminary review — Phase 1 blocker gate
Verified the findings against head d251934. The new pruning test uses a Bitcoin-specific filter collision that does not match Dash's regtest genesis; an independent calculation confirms the mismatch. The CI backport omission is explicitly documented in its commit message and does not require another review comment.
Validated blockers were found by the Phase-1 review and confirmed by a fresh verifier. Phase 2 is deferred until a fresh same-head revalidation clears the blocker gate.

- [BLOCKING] test/functional/feature_pruning.py:513: Use the Dash genesis filter collision in test_scanblocks_pruned
This newly added test retains Bitcoin's precomputed false-positive script, which does not collide with Dash's regtest genesis filter. Using the repository's SipHash implementation and Dash's genesis hash, the genesis output maps to 434268, while this script maps to 426531. Consequently, scanblocks returns no relevant block and the first assertion fails; the accurate-mode call also cannot reach the expected pruned-block error because the filter does not match. Replace this constant with the Dash-specific collision already used and dynamically verified in rpc_scanblocks.py, which maps to 434268. This mismatch was independently reproduced with a Python hash calculation, not a full functional-test run.

Resolved (re-reviewed at 7c026b78): The test now uses 1400000000000000000000000000000000000ad23b at line 513, replacing the incompatible Bitcoin vector. This value collides with the Dash regtest genesis basic-filter element, so the test exercises the intended filter false-positive path.

Withdrawn (re-reviewed at 62bab134): Your test already uses the correct Dash collision, including at the previously reviewed head. I independently calculated the ranged hashes as 434268 for both the supplied script and Dash regtest genesis output, so the earlier finding was mistaken rather than subsequently fixed.

Re-review — Final validation — Phase 1 + Phase 2
The backport introduces three in-scope blocking issues. Abandoning orphaned coinbase descendants does not restore wallet UTXOs or notify observers, accurate scanblocks matching does not apply basic-filter output exclusions, and the pruning test is not prepared for builds without wallet support.

- [BLOCKING] src/wallet/wallet.cpp:1103-1107: Reconcile wallet UTXOs when abandoning orphaned descendants
This traversal marks each descendant abandoned and calls MarkInputsDirty, but it never calls ReconcileWalletUTXOs. AddToSpends removed each descendant's inputs from setWalletUTXO when the transaction was first inserted; after the descendant becomes abandoned, IsSpent no longer considers that abandoned transaction a spend, but the inputs remain absent from the wallet UTXO set until the wallet is reloaded. The traversal also changes descendant states without notifying transaction observers, unlike RecursiveUpdateTxState.
In `src/rpc/blockchain.cpp`:
- [BLOCKING] src/rpc/blockchain.cpp:2844-2846: Exclude OP_RETURN outputs from accurate scan matching
BasicFilterElements excludes empty output scripts and scripts beginning with OP_RETURN, but CheckBlockFilterMatches compares every transaction output against the requested needles. If an OP_RETURN needle collides with an included basic-filter element, MatchAny selects the block and this exact-match pass then incorrectly accepts the excluded output as a real match. That violates filter_false_positives=true, which should return only blocks containing actual basic-filter elements.
In `test/functional/feature_pruning.py`:
- [BLOCKING] test/functional/feature_pruning.py:490-500: Synchronize node 5 when wallet support is disabled
Node 5 is connected and synchronized only inside wallet_test(), which is skipped when wallet support is not compiled. The unconditional test_scanblocks_pruned() call therefore runs against node 5 at genesis height. The Dash-specific collision makes the non-accurate scan find genesis, but accurate matching filters out that collision and returns normally instead of reaching the expected pruned-data error. The test fails in no-wallet builds.

Identical to upstream and still so on master. A needle starting with OP_RETURN that appears in the block is a real match of the block contents, only not an indexed one. No Dash-specific reason to diverge.

Withdrawn (re-reviewed at 62bab134): You're right: the second pass verifies block contents, not basic-filter membership, so an OP_RETURN script actually present in the block is a real content match. My earlier request imposed a restriction that this helper does not require.

08209c0 Correctly limit overview transaction list (John Moffett) Pull request description: Fixes dashpay#703 The way the main overview page limits the number of transactions displayed (currently 5) is not an appropriate use of Qt. Our subclassed transaction sort/filter proxy model returns a maximum of `5` in `rowCount()`. However, the model itself actually may hold significantly more. While this has _worked_, it breaks the contract of `rowCount()`. If `bitcoin-qt` is run with a DEBUG build of Qt, it'll result in an assert-crash in certain relatively common situations (see dashpay#703 for details). Instead of artificially limiting the `rowCount()` in the subclassed filter, we can hide/unhide the rows in the displaying `QListView` upon any changes in the sorted proxy filter. I loaded a wallet with 20,000 transactions and did not notice any performance differences between master and this branch. For reference, this is the list I'm referring to: <img width="934" alt="image" src="https://user-images.githubusercontent.com/116917595/214947304-3f289380-3510-487b-80e8-d19428cf2f0f.png"> ACKs for top commit: Sjors: tACK 08209c0 hebasto: ACK 08209c0, tested on Ubuntu 22.04.

Re-review — Final validation — Phase 1 + Phase 2
No actionable in-scope findings remain at the exact reviewed head: the pruning synchronization and Dash wallet UTXO fixes are present, and the OP_RETURN and genesis-collision findings do not apply. The omitted bitcoin#35070 validation fix is explicitly outside the selected test/documentation backport and is recorded separately as a pre-existing follow-up. Python parsing, shell syntax, diff checks, and an independent genesis-filter collision calculation passed; runtime suites and Qt compilation were not rerun.

Out-of-scope follow-up suggestions (1)
These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.
- Track the remaining unlinked-block ordering fix separately — Dash still has the direct m_blocks_unlinked insertions and sequence-ID update behavior addressed by bitcoin#35070's validation commits. Duplicate entries can cause the same block index to be processed again while its ordering key is used by setBlockIndexCandidates. These paths are unchanged from the review base, and commit 62bab13 explicitly selects only the independent test/documentation commit, so this is not a blocker for the advertised partial backport.
- Follow-up: Track a separate backport of bitcoin#35070's validation safety changes, preserving Dash's ChainLock-conflict handling.

Cherry-picked (`git cherry-pick -m1 -x`) every develop merge since rc.2 that carries `backport-candidate-24.0.x`, plus #7778, which #7807's test needs. They are in develop merge order: - #7778 test: use single-member in functional tests: feature_mnehf, feature_notifications, p2p_instantsend (test-only. Needed because #7807's `feature_evo_shares_activation.py` depends on its `mine_quorum_single_member()` fix and fails without it.) - #7791 fix(net): request object votes from nPeersPerHashMax peers - #7781 fix(rpc): use a consistent tip height in quorum dkgstatus - #7789 fix(qt): report malformed lang/font settings instead of aborting at startup - #7779 fix!: report legacy evonode Platform addresses when listdiff changes its address - #7795 backport: bitcoin#34272, partial bitcoin#31650 (pass PSBT by const reference in PSBTInputSignedAndVerified) - #7783 fix: stop fish completion from re-running the typed dash-cli command - #7794 fix(wallet): floor the denomination gap threshold so rebalancing cannot oscillate - #7785 fix: restore the txindex requirement when governance validation is enabled - #7787 fix: only sign EHF signals inside the deployment's start/timeout window - #7790 fix: guard cached governance object flags with the object lock - #7793 backport: partial bitcoin#28868 (wallet: reload wallet if migration exited early, keep mixed watchonly txs) - #7786 fix(net): keep a dedicated onion listener when -bind is given and correct the bind release note. Includes partial bitcoin#36170 (5f40d56). Upstream's dedicated-onion-bind changes to `feature_torcontrol.py` and `p2p_private_broadcast.py` are not included, because those tests depend on upstream commits (5693833, e74d54e) that Dash does not have. - #7796 backport: bitcoin#26720 (remaining), partial bitcoin#29523: weight-check the knapsack exact-match selection - #7803 fix: return non-zero amount of accounts after sethdseed - #7776 fix: keep a pending ProUpServTx across a registrar update that keeps the operator key - #7807 feat(consensus): hold EvoNode shares and multiple payouts behind a new evo_shares deployment One pick needed conflict resolution, in a test only, described in its commit message: #7793, `test/functional/wallet_migration.py`. `test_conflict_txs()` comes from bitcoin#28542 (#7762), which is not on this branch, so it is left out. The C++ part of #7793 is identical to develop. Merged since rc.2 but intentionally not included: #7775 (24.1 version bump), #7260 and #7804 (new Qt feature and its CI fix), #7584 (refactor), routine upstream backports #7257, #7759, #7762, #7768, #7788, #7801, and test/CI-only changes #7777 and #7797. No version change is needed. `configure.ac` is already 24.0.0 with `CLIENT_VERSION_IS_RELEASE` false, so the build takes its version string from the `v24.0.0-rc.3` tag, as it did for rc.2. ## How Has This Been Tested? Built on macOS arm64 against depends with `--enable-debug --enable-werror` (dashd, dash-qt, tests). - `make check`: all unit test suites pass, including `test_dash-qt`. - Functional tests, all passing: `feature_evo_shares_activation.py`, `feature_masternode_shares.py`, `feature_mnehf.py`, `feature_governance.py --descriptors`, `feature_governance_objects.py`, `feature_governance_txindex_devnet.py`, `feature_proxy.py`, `feature_notifications.py`, `feature_llmq_connections.py`, `feature_llmq_chainlocks_automatic.py`, `feature_llmq_singlenode.py`, `p2p_instantsend.py`, `rpc_blockchain.py` (v1 and v2 transport), `rpc_netinfo.py`, `rpc_quorum.py`, `rpc_verifychainlock.py`, `wallet_hd.py` (legacy and descriptors), `wallet_migration.py`. - `feature_bind_extra.py` (from #7786) only runs on Linux and was skipped locally, so CI covers it. Every touched file was diffed against develop. The remaining differences come only from develop PRs that are not part of this backport. ## Breaking Changes Carried over from the picked PRs: - #7807: consensus change behind the new `evo_shares` deployment (bit 14). Mainnet and testnet are unaffected until it activates. Devnets with `v24` already active and an EvoNode carrying several owner payouts need to check or reset. New RPC `protx shared_register_prepare_evo`. - #7785: outside regtest, a node with `-txindex=0` and without `-disablegovernance` refuses to start again, as before v23.1.0. - #7786: carries a partial bitcoin#36170. A node started with `-bind` but no specific `-bind=<addr:port>=onion` now refuses to start while `-listenonion` is enabled. That is the default when listening, even without Tor configured. A wildcard onion bind is also refused. Such nodes need `-bind=127.0.0.1:<port>=onion` or `-listenonion=0`. Nodes without `-bind`, including those using only `-whitebind`, keep the default `127.0.0.1:9996` (`19996` testnet) onion target. See `doc/release-notes-7300.md`. - #7779: `protx listdiff` now includes `platform_p2p` and `platform_https` for a legacy-address evonode whose core P2P address changes. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone 🤖 Generated with [Claude Code](https://claude.com/claude-code) Top commit has no ACKs.
