Walkthrough
The changes add mempool tracepoints, a BCC dashboard, and functional tests for added, removed, and rejected transactions. Prune settings move into BlockManager options passed through ChainstateManager. Node interfaces and initialization use context-provided arguments. Several timing measurements use clock durations, and exception reporting moves to a dedicated utility. The changes also update transaction relay locking, wallet coin-selection errors, and wallet rescan tests.

Full details: Description check
Explanation
The description is a brief backport note: it says the PR contains regular backports from Bitcoin Core v25, that unit and functional tests were run, and that there are no breaking changes. The changeset matches this. The summaries show many Bitcoin Core v25 backport changes, including the tracing and mempool monitor work, the ChainstateManager and BlockManager option refactor, pruning changes, time utility changes, and new functional tests. The description is short and generic, but it still identifies the nature of the changes, so it is related to the changeset and is not off-topic.

Increase the removal buffer to 64 pages.
struct removed_event occupies 72 bytes after alignment. The payload for 2,000 removals is therefore 144,000 bytes, which already exceeds the 128 KiB provided by 32 4 KiB pages. Perf-record overhead increases the required space.
BCC creates a per-CPU buffer, and its default wakeup_events=1 can wake the poller as soon as data arrives. The loss is therefore conditional on the reader being delayed or unable to drain the buffer during the removal burst, not guaranteed for every block. Sixty-four pages cover the stated approximate 2,000-event workload on 4 KiB pages, but not arbitrary bursts.
BCC's default lost_cb=None already reports lost events to stderr, so no custom callback is required solely for loss reporting.

The event-rate window starts at column 40 and has width 42. It therefore requires columns 40–81, which exceeds an 80-column terminal. Dashboard(screen) runs before the polling loop, so window creation can abort dashboard initialization.
Size or position the windows from screen.getmaxyx(). If the terminal is too small, report the required dimensions before creating the windows.

Apply the fixture’s prune argument before constructing ChainstateManager.
If ChainTestingSetup receives -prune in extra_args, this constructor still gives BlockManager a zero target. ChainstateLoadOptionsForTest() then reports prune = false, so a test configured for pruning runs with unpruned block-manager state. Apply node::ApplyArgsManOptions(*m_node.args, blockman_opts) before construction and check its result. The restart constructor in src/test/validation_chainstatemanager_tests.cpp:450 needs the same treatment if it must retain that configuration. (raw.githubusercontent.com)

Emit mempool:rejected only for invalid results.
When test_accept succeeds, the condition at Line 1749 still enters this branch. The new probe then reports a valid transaction as rejected, with an empty reason.

Count each rejected output once.
When m_avoid_partial_spends is enabled, both grouped passes can reject the same positive-value outputs. Line 521 then adds those outputs to ret_discarded_groups twice. AutomaticCoinSelection subtracts both copies. If other eligible outputs cover the target, the wallet can still reject a valid spend. Deduplicate rejected outputs across the two passes before calculating the discarded total. (raw.githubusercontent.com)

Keep the remaining balance as a CAmount.
The comparison initializes total_amount with 0 or 1, not with the balance left after filtering. For example, if eligible groups provide 25 units, a rejected long-chain group provides 10, and the target is 30, Line 731 compares 1 + 10 with 30. The wallet reports general insufficient funds instead of the long-chain error. Calculate the remaining amount first, then compare it with the target.

Compare amounts in the same units.
total_discarded sums GetSelectionAmount(), which is usually the fee-adjusted effective value. GetTotalAmount() returns the raw output value. If fees make raw value exceed effective value, subtracting the effective discarded value overstates the balance eligible for selection. The check can skip the long-chain diagnosis and return general insufficient funds instead. Use the effective available total when m_subtract_fee_outputs is false, as SelectCoins does.

GetTimeMicros() reads the system clock, which can jump, and hides the unit
in a plain int64_t. bitcoin#27233 removes it; the remaining Dash callers in
cbtx.cpp, simplifiedmns.cpp, specialtxman.cpp, httprpc.cpp and
DisconnectTip() all measure elapsed time, so switch them to SteadyClock
durations and Ticks<>() the way ConnectBlock() already does.
faf3f12 refactor: Replace GetTimeMicros by SystemClock (MarcoFalke)
Pull request description:
It is unclear from the name that `GetTimeMicros` returns the system time. Also, it is not using the type-safe `std::chrono` types.
Fix both issues by replacing it with `SystemClock` in the only place it is used.
This refactor should not change behavior.

Pull request description:
Currently `node/interfaces.cpp` uses a mix of `gArgs` vs `m_context->args`. This is fine, because outside of tests those should be identical. However, it makes the code inconsistent and harder to use in tests.
Fix that by using `args` from the context consistently. Do the same in `init.cpp`, where `gArgs` and `args` are inconsistently used in the same scope or even line.

aaced56 refactor: Move error() from util/system.h to logging.h (Ben Woosley)
e7333b4 refactor: Extract util/exception from util/system (Ben Woosley)
Pull request description:
This pull request is part of the `libbitcoinkernel` project bitcoin#24303https://github.com/bitcoin/bitcoin/projects/18 and more specifically its "Step 2: Decouple most non-consensus code from libbitcoinkernel". These commits were originally authored by empact and are taken from their parent PR bitcoin#25152.
#### Context
There is an ongoing effort to decouple the `ArgsManager` used for command line parsing user-provided arguments from the libbitcoinkernel library (bitcoin#25290, bitcoin#25487, bitcoin#25527, bitcoin#25862, bitcoin#26177, and bitcoin#27125). The `ArgsManager` is defined in `system.h`.
#### Changes
Next to providing better code organization, this PR removes some reliance of the tree of libbitcoinkernel header includes on `system.h` (and thus the `ArgsManager` definition) by moving some logging functions out of the `system.*` files.
Further commits splitting more functionality out of `system.h` are still in bitcoin#25152 and will be submitted in separate PRs once this PR has been processed.

Dash: fImporting stays a node-level global instead of moving into
BlockManager::m_importing. CInstantSendManager::IsInstantSendEnabled()
reads it, and that manager is constructed before ChainstateManager (the
mempool and chainman hold pointers to it), so it cannot take a
BlockManager reference without reordering init. The ImportingNow helper
is still switched to the upstream shape and takes the flag by reference.
4b7aec2 Add mempool tracepoints (virtu)
Pull request description:
This PR adds multiple mempool tracepoints.
| tracepoint | description |
| ------------- | ------------- |
| `mempool:added` | Is called when a transaction enters the mempool |
| `mempool:removed` | ... when a transaction is removed from the mempool |
| `mempool:replaced` | ... when a transaction is replaced in the mempool |
| `mempool:rejected` | ... when a transaction is rejected from entering the mempool |
The tracepoints are further documented in `docs/tracing.md`. Usage is demonstrated in the example script `contrib/tracing/mempool_monitor.py`. Interface tests are provided in `test/functional/interface_usdt_mempool.py`.
The rationale for passing the removal reason as a string instead of numerically is that the benefits of not having to maintain a redundant enum-string mapping seem to outweigh the small cost of string generation. The reject reason is passed as string as well, although in this instance the string does not have to be generated but is readily available.

49d01f3 kernel: add missing include (Cory Fields)
Pull request description:
This syncs the cs_main definition/declaration.
Noticed when experimenting with the external visibility of `cs_main`.
Specifically, this is needed for the following to work as intended:
```c++
__attribute__ ((visibility ("default"))) extern RecursiveMutex cs_main;
```

fa0696e test: Replace threading with concurrent.futures (MarcoFalke)
Pull request description:
`threading` has no easy way to get the return value or exception once the target function stops. Not checking the return value or exception can make tests more fragile and failures harder to debug.
Fix this by checking the return value (or exception) by wrapping the function execution into a future and calling `result()` on it.
Can be reviewed with `--ignore-all-space`.
(There are still some uses of `threading` around, because some tests do expect an exception to be thrown and caught in the target function)

Final validation — Phase 1 + Phase 2
Static verification at head 02adc29 found no actionable in-scope issues: the reported asset-unlock null dereference is prevented by the command mapping, and the omitted replacement tracing coverage follows Dash’s explicitly documented RBF exclusion. Current CI reports no failures; standard Linux tests now pass, while ASan/TSan tests and the multiprocess build remain pending. The supplied base-drift evidence identifies a conflict in test/functional/wallet_create_tx.py with #7990’s independent CompactSize fee tests; merge resolution should preserve both test additions.
Triage: normal by gpt-6.1-sol (effort low) — The backports span many files but mostly add tracing, refactor infrastructure, and adjust tests, while the localized coin-selection error-handling change in src/wallet/spend.cpp is not large or intricate enough to meet the critical tier.

Re-review — Final validation — Phase 1 + Phase 2
The complete diff at d292758 has no confirmed actionable findings; the omitted replacement tracepoint and test follow Dash’s explicitly documented exclusion of RBF. Current CI reports successful standard Linux, no-wallet and SQLite tests, linting, and completed platform builds; ASan and TSan tests and the multiprocess build remain pending. Verification was static-only, the worktree is unchanged, and the supplied base-drift evidence reports no conflicting files.
Triage: normal by gpt-6.1-sol (effort low) — The cross-cutting backports refactor block-storage configuration and add mempool tracing, utilities, and tests, but do not clearly change consensus rules, funds handling, cryptography, peer-facing deserialization, or storage migrations.

## Issue being fixed or feature implemented
Split from #7999 as it requires extra backports and 7999 is already over-size.
## What was done?
Regular backports from Bitcoin Core v25 + 2 extra backports from the latest versions with relevant fixes.
## How Has This Been Tested?
Run unit & functional tests.

## Final validation — Phase 1 + Phase 2
Verified the combined reviewer evidence against head ad9bef6 and the upstream patches. No blocking merge-resolution or Dash-specific correctness issue was confirmed; one non-blocking suggestion remains for omitted upstream unit coverage and its supporting declaration. Static diff checks passed without modifying files; current CI builds, lint, and completed tests pass, with linux64_multiprocess-test / Test source still pending.

**🟡 Suggestion: Declared partial backport omits bitcoin#36284 unit regression coverage**
`src/wallet/test/group_outputs_tests.cpp:201-205`
Upstream bitcoin#36284 adds a direct regression assertion immediately after this check: call the five-argument GroupOutputs overload with avoid_partial_spends enabled and verify discarded_groups.size() == 2U. Dash already has both depth-ineligible fixture UTXOs and the required selection-parameter helper, but this backport omits that assertion and the supporting declaration in spend.h. Include both upstream hunks while retaining Dash's LEGACY fixture adaptation. The missing header declaration is not independently a production interface defect: current external callers use the preserved four-argument overload, and the five-argument implementation is visible to its production callers in spend.cpp. The BACKPORT NOTE explicitly documents the omission, and the functional regression is retained, so this is non-blocking test completeness rather than a missing production prerequisite. If the unit coverage is deferred, link a tracking issue for the omitted hunks.
