@knst, the quoted SubmitPackage definition passes results by reference. The supplied current src/validation.cpp content also uses the reference parameter in both the declaration and definition.
The repository verification failed because the sandbox could not clone the repository. I cannot confirm the exact commit relationship for 3701de0baa1878162538c42129ede2c703f56b08. Please retry the verification. The original finding appears stale or based on a different revision.

Final validation — Phase 2 only (queue backlog)
Verified the supplied findings against head 66d8a2d and the local upstream commit history. The reported SubmitPackage compile failure is a false positive: results already references a mutable map. Two test-coverage omissions are confirmed, and the advertised full bitcoin#26646 backport needs explicit exclusion metadata for omitted witness/replacement test sections; no Dash build or functional tests were run.

- [SUGGESTION] test/functional/rpc_packages.py:277-279: Restore the omitted #26646 RPC fee-result assertions
Upstream #26646 tracks presubmitted transactions and checks effective-feerate and effective-includes for each newly accepted transaction in test_submit_child_with_parents. This backport replaces the old whole-result comparison with individual field checks but omits those new assertions, leaving the new RPC fields unchecked in this scenario. Restore the tracking set and assertions using txids. The modified-fees test also checks only individually accepted transactions, whereas upstream checks a shared parent/child effective feerate and a two-transaction effective-includes list. Dash's existing minimum-relay-fee policy justifies changing the zero-fee-parent setup, but retain equivalent aggregate-result coverage using fees above minimum relay and below a raised mempool minimum.
In `src/test/txpackage_tests.cpp`:
- [SUGGESTION] src/test/txpackage_tests.cpp:516-522: Restore two dropped #26646 effective-feerate unit checks
Upstream #26646 checks that both the parent and child of the prioritised package report expected_feerate. The backport checks only the child here, although it retains both transactions' fee-calculation membership checks. It also omits the upstream assertion that the accepted rich parent's effective feerate equals CFeeRate(high_parent_fee, GetVirtualTransactionSize(*tx_parent_rich)) in the case around lines 561–566. Restore both parent assertions; the test cases and required API already exist, and neither omission is needed for Dash's fee-policy adaptations.
In `test/functional/mempool_dust.py`:
- [BLOCKING] test/functional/mempool_dust.py:79-86: Document the complete witness and replacement-test exclusions
The #26631 commit is explicitly partial and mentions both missing Taproot descriptors and a witness/Taproot fixup; its omitted dust cases are P2WPKH, P2WSH, P2TR, and future witness versions 2 and 16. The separate #26646 commit is still advertised as a full backport, but omits upstream additions to package_witness_swap_tests, the effective-fee assertions in rpc_packages.py's test_rbf, and the response-shape updates in p2p_segwit.py. Those sections exist before upstream #26646 but are absent from Dash's base and head. Under the full-backport completeness requirement, absent prerequisite test sections need an explicit exclusion rather than silently disappearing. Mark #26646 as partial and enumerate the intentionally excluded witness/replacement hunks in the backport metadata, or supply the missing coverage. This is a backport-scope blocker, not a demonstrated runtime failure or a request to introduce SegWit or RBF into Dash.

Re-review — Final validation — Phase 2 only (queue backlog)
The backport includes a blocking functional-test initialization regression: DashTestFramework gives MiniWallet a single coinbase output that remains immature, while subsequent mining pays the node wallet instead. The retained package-result test coverage also omits effective-feerate assertions for the parent and the corresponding RPC fee-result assertions. Witness, SegWit, and replacement-related omissions are intentional Dash exclusions and are not findings.

(existing thread: https://github.com/dashpay/dash/pull/7684#discussion_r4021033407)
The prioritized package case verifies `m_effective_feerate` only for the child. Both the parent and child results should carry the package effective feerate, so a regression affecting only the parent's result would pass unnoticed. Add the corresponding parent assertion alongside the existing child assertion.

In `test_submit_child_with_parents`, the loop checks transaction IDs, sizes, and base fees but does not assert the new `fees.effective-feerate` and `fees.effective-includes` fields. The implementation returns these fields, and this package path should verify them for each parent and the child so regressions in the RPC result adaptation are detected.

Maturity is a chain-depth property, not a matter of who later coinbases pay.
getbalance() excludes immature coinbases, so while getbalance() < required_balance: generate(10) can't exit before height ≥ 111 (first wallet coinbase is block 2, mature at 102, checked in 10-block chunks), then etup_network mines 8 more. Block 1's coinbase has >100 confirmations before any run_test starts. Empirically: every functional-test job in that CI run passed, and rpc_net.py — the only DashTestFramework test that uses MiniWallet, and it does send_self_transfer — is among them.

Withdrawn (re-reviewed at ed09b596): You are right that maturity is chain depth rather than who later coinbases pay, and the getbalance loop plus setup blocks mature block 1's coinbase with rpc_net passing in CI, so I withdraw this blocking claim.

⚠️ DEGRADED — Re-review — Final validation — Phase 1 + Phase 2
⚠️ DEGRADED review. The primary review models were unavailable (gpt-6-astraunavailable: All credentials for model gpt-6-astra are cooling down (last error: usage_limit_reached: The usage limit has been reache), so this review ran on stand-in models:gpt-5.6-luna→muse-spark-1.3-contributor,gpt-5.6-sol→muse-spark-1.3-contributor,gpt-5.6-terra→muse-spark-1.3-contributor,gpt-6-astra→muse-spark-1.3-contributor. Both review phases and the independent verifiers still ran, but on weaker models, with Phase 1 capped athigheffort. Treat the verdict as provisional; a full-strength re-review will run on the next push once the primary models are back.
Backport batch is faithfully adapted at this head: the bitcoin#26646 effective-feerate unit and RPC assertions are present and the MiniWallet setup matures its coinbase via chain depth. Two hygiene items remain: the partial bitcoin#26631 merge message still ends with two stray fixup lines, and the PR title claims bitcoin#26905 while its clang-tidy collapse never landed.

🟡 Suggestion: Remove the stray fixup marker from the backport message
<commit:0ae5209d81b>:1
The partial bitcoin#26631 merge (0ae5209) still ends its message with leftover squash-fixup text below the Tree-SHA512 stanza: 'fixup taproot & witness mempool_dust.py' with a Co-authored-by trailer, and 'fixup mempool-dist 26631'. These lines will live forever in git log/blame. Reword the commit to delete those trailing lines while keeping the BACKPORT NOTE that documents the intentional Taproot/witness exclusion.

- [SUGGESTION] <commit:0ae5209d81b>:1: Remove the stray fixup marker from the backport message
The partial #26631 merge (0ae5209d81b) still ends its message with leftover squash-fixup text below the Tree-SHA512 stanza: 'fixup taproot & witness mempool_dust.py' with a Co-authored-by trailer, and 'fixup mempool-dist 26631'. These lines will live forever in git log/blame. Reword the commit to delete those trailing lines while keeping the BACKPORT NOTE that documents the intentional Taproot/witness exclusion.
In `src/.clang-tidy`:
- [SUGGESTION] src/.clang-tidy:18-29: Claimed backport bitcoin#26905 has no landing commit
The PR title advertises bitcoin#26905 but no commit in the base..head range lands it: the range log shows merges for #26186, #26251, #26471, #26631, #26646, #26877, #26884, #26886, #26887 and #26991 plus Dash-only fix/docs commits, with no #26905 subject, and the base..head diff for src/.clang-tidy is empty with the WarningsAsErrors list (lines 18-29) byte-identical to base. Lint-config only with no functional impact, so either land the one-hunk collapse to '*' adapted to Dash's diverged list, or drop #26905 from the title to keep the scope claim accurate.

…mpare to upstream bitcoin core for agent's context 56d231f docs: clear up bips.md list from BIPs that are completely irrelevant to Dash Core (Konstantin Akimov) 9a80b6f chore: add list of features that absent for dash core compare to upstream bitcoin core (Konstantin Akimov) Pull request description: ## Issue being fixed or feature implemented Reviewing agents are often triggered by missing "prerequisites" or "backport is not full but partial" false alarm if the feature is meant to be skipped intentionally. There's example of alerts that I see on GitHub for backports: #7646 (comment) > **:red_circle: Blocking: Missing fee-bumper prerequisite chain for bitcoin#25344 > Upstream merge 73966f7 adds an outputs option to bumpfee_helper, parses it through AddOutputs, forwards replacement outputs through feebumper::CreateRateBumpTransaction, updates feebumper.{cpp,h} and wallet/interfaces.cpp, and adds wallet_bumpfee.py coverage. This backport changes only the generic raw-transaction helpers and documentation because Dash lacks the fee-bumper implementation and bumpfee/psbtbumpfee RPC chain. Commit 0c8c405 and the PR title nevertheless advertise bitcoin#25344 as a full merge. Backport the applicable prerequisites and omitted behavior/tests, or explicitly mark and document bitcoin#25344 as partial. #7684 (comment) > **:red_circle: Blocking: Document the complete witness and replacement-test exclusions** > The bitcoin#26631 commit is explicitly partial and mentions both missing Taproot descriptors and a witness/Taproot fixup; its omitted dust cases are P2WPKH, P2WSH, P2TR, and future witness versions 2 and 16. The separate bitcoin#26646 commit is still advertised as a full backport, but omits upstream additions to package_witness_swap_tests, the effective-fee assertions in rpc_packages.py's test_rbf, and the response-shape updates in p2p_segwit.py. Those sections exist before upstream bitcoin#26646 but are absent from Dash's base and head. Under the full-backport completeness requirement, absent prerequisite test sections need an explicit exclusion rather than silently disappearing. Mark bitcoin#26646 as partial and enumerate the intentionally excluded witness/replacement hunks in the backport metadata, or supply the missing coverage. This is a backport-scope blocker, not a demonstrated runtime failure or a request to introduce SegWit or RBF into Dash. As well, it happens also with automated backports flow [dashcoreautoguix], that had been active in the past: It attempted to do completely irrelevant backports, such as `bitcoin#26107: [test] only run feature_rbf.py once` - see DashCoreAutoGuix#74 ## What was done? Added a list of features that meant to be always omitted for Dash Core and should not be considered as "missing" or "forgotten" or "required" by reviewing agents. ## How Has This Been Tested? Let's see how agents will do review on github. ## Breaking Changes N/A ## Checklist: _Go over all the following points, and put an `x` in all the boxes that apply._ - [x] I have performed a self-review of my own code - [ ] I have commented my code, particularly in hard-to-understand areas - [ ] I have added or updated relevant unit/integration/functional/e2e tests - [ ] I have made corresponding changes to the documentation - [x] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ Top commit has no ACKs.

Bug: In package validation, we first try the transactions individually (see doc/policy/packages.md for more explanation) and, if they all failed for missing inputs and policy-related (i.e. fee) reasons, we'll try package validation. Otherwise, we'll just "quit early" since, for example, if a transaction had an invalid signature, adding a child will not help make it valid. Currently, when we quit early, we're not setting the `package_state` to be invalid, so the caller might think it succeeded. Also, we're returning no results - it makes more sense to return the individual transaction failure. Thanks instagibbs for catching bitcoin#25038 (comment)! Also, make the package results interface generally more useful/predictable: - Always return the feerate at which a transaction was considered for `CheckFeeRate` in `MempoolAcceptResult::m_effective_feerate` when it was successful. This can replace the current `PackageMempoolAcceptResult::m_package_feerate`, which only sometimes exists. - Always provide an entry for every transaction in `PackageMempoolAcceptResult::m_tx_results` when the error is `PCKG_TX`.

Segwit / witness are meant to be skipped ---- d6fc1d6 test: add coverage for dust mempool policy (`-dustrelayfee` setting) (Sebastian Falbesoner) 8a5dbe2 test: add `CScript` method for checking for witness program (Sebastian Falbesoner) Pull request description: This PR adds missing test coverage for the `-dustrelayfee` setting, which specifies the fee-rate used to define dust. Output scripts for all common types that are treated as standard by default (P2PK, P2(W)PKH, P2(W)SH, P2TR, bare multisig, null data, unknown witness versions v2+) are created and then checked for dust-mempool-policy each via the `testmempoolaccept` RPC: a tx with an output's nValue equal to the dust threshold should be accepted, one with an nValue of just one 1 satoshi below that should be rejected with reason `dust`. This is repeatedly done for a fixed (but obviously somewhat arbitrary) list of different `-dustrelayfee` settings on a single node, including the default and zero (i.e. no dust limit) settings. Note that the first commit introduces a necessary `CScript` helper method `IsWitnessProgram` (using PascalCase in Python is likely controversial; in this case the style for the already existing method `GetSigOpCount` was followed, which also refers to a method in the core `CScript` class). Some historical information about dust, contributed by pablomartin4btc: "The concept of dust was first introduced in bitcoin#2577. This [commit](bitcoin@eb30d1a) from bitcoin#9380 introduced the -dustrelayfee option. Previous to that PR, the dust feerate was whatever -minrelaytxfee was set to."

Note that in contrast to the name, the setting does not only apply to change outputs, but in fact to _all_ unconfirmed outputs that we sent to ourselves, i.e. we can trigger the testing path simply with a single recipient address.

In comparison to bitcoin#9569 which either set `maxmempool` size to 0 when `-blocksonly` was set or else errored on startup, this change will permit `maxmempool` options being set. This preserves the current (surprising?) behaviour of having a functional mempool in `-blocksonly` mode, to permit whitelisted peer transaction relay, whilst reducing average runtime memory usage for blocksonly nodes which either use the default settings or have otherwise configured a `maxmempool` size.

Keep package-wide errors result-free.
AcceptMultipleTransactions() returns PCKG_POLICY with an empty m_tx_results map when the dynamic package-fee check fails. If the package includes an already-mempool parent, AcceptPackage() stores that parent in results_final and unconditionally merges it here. The result then violates the PackageMempoolAcceptResult contract. Guard this merge so it runs only for valid or transaction-specific package outcomes.

Breaking Changes
Updated settings
Setting
-blocksonlywill now reduce the maximum mempool memoryto 5MB (users may still use
-maxmempoolto override). Previously,the default 300MB would be used, leading to unexpected memory usage
for users running with
-blocksonlyexpecting it to eliminatemempool memory usage.
As unused mempool memory is shared with dbcache, this also reduces
the dbcache size for users running with
-blocksonly, potentiallyimpacting performance.
JSON-RPC
The
testmempoolacceptRPC now returns 2 additional results within the "fees" result:"effective-feerate" is the feerate including fees and sizes of transactions validated together if
package validation was used, and also includes any modified fees from prioritisetransaction. The
"effective-includes" result lists the txids of transactions whose modified fees and sizes were used
in the effective-feerate (#7684).
