Pull request description:
I think this job should exist in this repo (not just qa-assets), if the alternative is double-handling changes to the interpreter. #32998 made changes which were then re-changed in #33600, to work around a false positive.
The unchached runtime of this job with `-lg` is `~32m`, with `-md` it's `~43m`.
Timeout is set to 150m, as the slow GHA runners were close to hitting a 120m limit.

Correct runner type selection for the lint job.
This was erroneously left-out during refactor of the runner selection mechanism in #33302 causing the lint job to run on GH hosts (and therefore not be able to acces local cirrus caches).

b4d0288c467f82a94041b51d10d38e66bb5c33ae doc: update Guix INSTALL.md (fanquake)
Pull request description:
It's somewhat annoying that Guix is falling out of being packaged by distros. For some more context, see https://lwn.net/Articles/1035491/.
> However, it is likely that the [Guix](https://guix.gnu.org/en/) package manager will soon be removed from the repositories for Debian 13 and Debian 12 ("bookworm", also called oldstable).
This seems to be happening. You can't `apt install guix` using the current release of Debian. https://packages.debian.org/search?keywords=guix. Guix is not going to be included in next release of Ubuntu (`25.10`): https://packages.ubuntu.com/search?keywords=guix.
Looking at https://aur.archlinux.org/packages/guix, comments over the last few months seem to indicate that the build is broken.
A 1.5.0 release is planned for sometime in January 2026: https://codeberg.org/guix/release-planning/wiki/release-1.5.0-project/. So hopefully the situation is going to improve in future.

The options used were wrong in two ways: firstly they were not enforced
as a "choice" (i.e. invalid input valudes could be provided without
error) and one of the options was listed as `gh` when we passed it as
`gha` from ci.yml.
"Fix" this by removing the choice altogether but sanity-testing the
input value against an expected list using a GHA "warning" to notify of
unknown inputs.

Pull request description:
GitHub Actions does not offer any way to determine the pull request number in a machine readable way from the checks API. See https://github.com/bitcoin/bitcoin/issues/27178#issuecomment-1503475232.
However, the pull request number can be useful for external tools to act on CI results.
Fix that by using a check run annotation for a single task named `debug_pull_request_number_str`.
This should re-enable the 'CI Failed' labelling mechanism via 1f24cc1ab9.

Previously the `bool relay` argument to `BroadcastTransaction()` designated:
```
relay=true: add to the mempool and broadcast to all peers
relay=false: add to the mempool
```
Change this to an `enum`, so it is more readable and easier to extend with a 3rd option. Consider these example call sites:
```cpp
Paint(true);
// Or
Paint(/*is_red=*/true);
```
vs
```cpp
Paint(RED);
```

b6f8c48946cbfceb066de660c485ae1bd2c27cc1 coins: increase default `dbbatchsize` to 32 MiB (Lőrinc)
8bbb7b8bf8e3b2b6465f318ec102cc5275e5bf8c refactor: Extract default batch size into kernel (Lőrinc)
Pull request description:
This change is part of [[IBD] - Tracking PR for speeding up Initial Block Download](https://github.com/bitcoin/bitcoin/pull/32043)
### Summary
When the in-memory UTXO set is flushed to LevelDB (after IBD or AssumeUTXO load), it does so in batches to manage memory usage during the flush.
A hidden `-dbbatchsize` config option exists to modify this value. This PR only changes the default from `16` MiB to `32` MiB.
Using a larger default reduces the overhead of many small writes and improves I/O efficiency (especially on HDDs). It may also help LevelDB optimize writes more effectively (e.g., via internal ordering).
The change is meant to speed up a critical part of IBD: dumping the accumulated work to disk.
### Context
The UTXO set has grown significantly since [2017](https://github.com/bitcoin/bitcoin/pull/10148/files#diff-d102b6032635ce90158c1e6e614f03b50e4449aa46ce23370da5387a658342fdR26-R27), when the original fixed 16 MiB batch size was chosen.
With the current multi-gigabyte UTXO set and the common practice of using larger `-dbcache` values, the fixed 16 MiB batch size leads to several inefficiencies:
* Flushing the entire UTXO set often requires thousands of separate 16 MiB write operations.
* Particularly on HDDs, the cumulative disk seek time and per-operation overhead from numerous small writes significantly slow down the flushing process.
* Each `WriteBatch` call incurs internal LevelDB overhead (e.g., MemTable handling, compaction triggering logic). More frequent, smaller batches amplify this cumulative overhead.
Flush times of 20-30 minutes are not uncommon, even on capable hardware.
### Considerations
As [noted by sipa](https://github.com/bitcoin/bitcoin/pull/31645#issuecomment-2587500105), flushing involves a temporary memory usage increase as the batch is prepared. A larger batch size naturally leads to a larger peak during this phase. Crashing due to OOM during a flush is highly undesirable, but now that [#30611](https://github.com/bitcoin/bitcoin/pull/30611) is merged, the most we'd lose is the first hour of IBD.
Increasing the LevelDB write batch size from 16 to 32 MiB raised the measured peaks by ~70 MiB in my tests during UTXO dump. The option remains hidden, and users can always override it.
The increased peak memory usage (detailed below) is primarily attributed to LevelDB's `leveldb::Arena` (backing MemTables) and the temporary storage of serialized batch data (e.g., `std::string` in `CDBBatch::WriteImpl`).
Performance gains are most pronounced on systems with slower I/O (HDDs), but some SSDs also show measurable improvements.
### Measurements:
AssumeUTXO proxy, multiple runs with error bars (flushing time is faster that the measured loading + flushing):
* Raspberry Pi, dbcache=500: ~30% faster with 32 MiB vs 16 MiB, peak +~75 MiB and still < 1 GiB.
* i7 + HDD: results vary by dbcache, but 32 MiB usually beats 16 MiB and tracks close to 64 MiB without the larger peak.
* i9 + fast NVMe: roughly flat across 16/32/64 MiB. The goal here is to avoid regressions, which holds.
### Reproducer:
```bash
# Set up a clean demo environment
rm -rfd demo && mkdir -p demo
# Build Bitcoin Core
cmake -B build -DCMAKE_BUILD_TYPE=Release && cmake --build build -j$(nproc)
# Start bitcoind with minimal settings without mempool and internet connection
build/bin/bitcoind -datadir=demo -stopatheight=1
build/bin/bitcoind -datadir=demo -blocksonly=1 -connect=0 -dbcache=3000 -daemon
# Load the AssumeUTXO snapshot, making sure the path is correct
# Expected output includes `"coins_loaded": 184821030`
build/bin/bitcoin-cli -datadir=demo -rpcclienttimeout=0 loadtxoutset ~/utxo-880000.dat
# Stop the daemon and verify snapshot flushes in the logs
build/bin/bitcoin-cli -datadir=demo stop
grep "FlushSnapshotToDisk: completed" demo/debug.log
```

This PR originally proposed 64 MiB, then a dynamic size, but both were dropped: 64 MiB increased peaks more than desired on low-RAM systems, and the dynamic variant underperformed across mixed hardware. 32 MiB is a simpler default that captures most of the gains with a modest peak increase.
For more details see: https://github.com/bitcoin/bitcoin/pull/31645#issuecomment-3234329502

While the PR isn't about IBD in general, rather about a critical section of it, I have measured a reindex-chainstate until 900k blocks, showing a 1% overall speedup:

Using std::ranges::copy from the C++ standard library has a few benefits here:
* It has the additional benefit of being a bit more type safe and document the byte cast explicitly.
* The compiler will likely optimize it to the same asm, but performance doesn't really matter here anyway.
* It has defined semantics for empty source ranges.

66667d6512294fd5dd02161b7c68c19af0865865 test: Use same rpc timeout for authproxy and cli (MarcoFalke)
Pull request description:
It seems odd to use different timeouts (and timeout factors) depending on whether the Python RPC proxy is used, or the bitcoin rpc command line interface.
Fix it by using the same timeout.
This can be tested by introducing a timeout error and checking it happens with and without `--usecli` after the exact same time.
Example timeout error:

5fa81e239a39d161a6d5aba7bcc7e1f22a5be777 test: add valid tx test with minimum-sized ECDSA signature (8 bytes DER-encoded) (Sebastian Falbesoner)
Pull request description:
Currently in our tests, all ECDSA signatures passing verification have sizes of 69 bytes and above (that's the DER-encoded size, i.e. counted without the sighash flag byte) [1]. This PR adds test coverage for the minimum-sized valid case of 8 bytes, by taking an interesting testnet transaction that I stumbled upon:
https://mempool.space/testnet/tx/c6c232a36395fa338da458b86ff1327395a9afc28c5d2daa4273e410089fd433
Note that this is a very obscure construction that only works because the public key used isn't contained in the locking script, but calculated and provided later at spending time (see https://bitcointalk.org/index.php?topic=1729534.msg17309060#msg17309060 for an explainer), to match the message (sighash) and picked signature. So this doesn't represent a use-case that really makes sense in practice, but it can still appear in a block (not in mempool though, due to `SCRIPT_VERIFY_CONST_SCRIPTCODE`), and having test-coverage seems useful.
Can be tested with same patch below (tests crash with the condition `>= 9`, but pass with `>= 8`).
[1] this can be verified by applying the following patch and running the tests:

Fixes: 33735
Correct runner type selection for the lint job.
This was erroneously left-out during refactor of the runner selection
mechanism in #33302 causing the lint job to run on GH hosts (and
therefore not be able to acces local cirrus caches).
Using std::ranges::copy from the C++ standard library has a few benefits
here:
* It has the additional benefit of being a bit more type safe and
document the byte cast explicitly.
* The compiler will likely optimize it to the same asm, but performance
doesn't really matter here anyway.
* It works around an UB-Sanitizer bug, when the source range is empty.

faed118fb30fbc303e9d4c70569abfee397f1759 build: Bump clang minimum supported version to 17 (MarcoFalke)
Pull request description:
Most supported operating systems ship with clang-17 (or later), so bump the minimum to that and allow new code to drop workarounds for previous clang bugs.
(Apart from dropping the small workaround, this bump allows the `ci_native_nowallet_libbitcoinkernel` CI to run on riscv64 without running into an ICE with clang-16.)
This patch will only be released in version 31.x, next year (2026).
For reference:
* https://packages.debian.org/bookworm/clang-19
* https://packages.ubuntu.com/noble/clang (clang-18)
* CentOS-like 8/9/10 ship clang-17 (and later) via Stream
* FreeBSD 12/13 ship clang-17 (and later) via packages
* OpenSuse Tumbleweed ships with https://software.opensuse.org/package/clang (clang21); No idea about OpenSuse Leap
On operating systems where the clang version is not shipped by default, the user would have to use GCC, or install clang in a different way. For example:
* https://packages.debian.org/bookworm/g++ (g++-12)
* https://packages.ubuntu.com/jammy/g++ (g++-11)
* https://apt.llvm.org/, or nix, or guix, or compile clang from source, ...
*Ubuntu 22.04 LTS does not ship with clang-16 (the previous minimum required), nor with clang-17, so one of the above workarounds is needed there.*
macOS 14 is unaffected, and the previous minimum requirement of Xcode15.0 remains, see also 919e6d01e9/depends/hosts/darwin.mk (L3-L4). (Modulo compiling the fuzz tests, which requires 919e6d01e9/.github/workflows/ci.yml (L149))

Pull request description:
The main goal is to remove [deprecated](https://github.com/bitcoin/bitcoin/issues/32361) code (removed in C++26).
This PR employs Microsoft's modern [approach](https://learn.microsoft.com/en-us/windows/apps/design/globalizing/use-utf8-code-page) to handling UTF-8:
> Until recently, Windows has emphasized "Unicode" -W variants over -A APIs. However, recent releases have used the ANSI code page and -A APIs as a means to introduce UTF-8 support to apps. If the ANSI code page is configured for UTF-8, then -A APIs typically operate in UTF-8. This model has the benefit of supporting existing code built with -A APIs without any code changes.
TODO:
- [x] Handle application manifests properly when building with MSVC.
- [x] Bump the minimum supported Windows version to 1903 (May 2019 Update).
- [x] Remove all remaining use cases of the deprecated `std:wstring_convert`.
- The instance in `subprocess.h` will be addressed in a follow-up PR, as additional tests are likely needed.
- The usage in `common/system.cpp` is handled in https://github.com/bitcoin/bitcoin/pull/32566.
Resolves partially https://github.com/bitcoin/bitcoin/issues/32361.

53874f7934d50f68ea46df68b2bcd11bad834730 doc: test: update TestShell example instructions/options (Sebastian Falbesoner)
Pull request description:
This PR adds a functional framework test for the `TestShell` class. The primary motivation for this is to avoid that the example instructions for the interactive Python shell in `test-shell.md` get outdated or broken without noticing, a problem we had already several times in the past (see #26520, #27906, #31415). Having a copy is still not perfect, as docs and functional test have to be kept in sync, but I don't expect this to be a problem in practice, assuming the hint in the functional test comment is hopefully noticed if changes are made.
Alternatively, the example instructions in `test-shell.md` could be removed with a hint to the functional test (I tend to prefer to keep the docs as-is though, showing the full REPL interaction).
The first commit contain two small removal fix-ups in `test-shell.md` regarding the result of the `createwallet` RPC call and the mentioning of the `noshutdown` option that was removed earlier (see #31620). Could be backported to v30.

Pull request description:
This PR is a simple refactoring that does four things:
1. Renames `test/policy_fee_tests.cpp` to `test/feerounder_tests.cpp`.
2. Renames `policy/fees.{h,cpp}` to `policy/fees/block_policy_estimator.{h,cpp}`.
3. Renames `policy/fees_args.cpp` to `policy/fees/block_policy_estimator_args.cpp`.
4. Modifies `estimateSmartFee` to return the block height at which the estimate was made by adding a `best_height` unsigned int value to the `FeeCalculation` struct.
**Motivation**
In preparation for adding a new fee estimator, the `fees` directory is created so we can organize code into `block_policy_estimator` and `mempool` because
a) It would be clunky to add more code directly under `fees`.
b) Having `policy/fees.{h,cpp}` and `policy/mempool.{h,cpp}` would also be undesirable.
Therefore, it makes sense to structure the it as `policy/fees/block_policy_estimator`, `policy/fees/mempool`, etc.
Hence test file were also updated accordingly.
The current block height is also returned because later in #30157 we log the height at which each estimate is made (at the debug log category of fee estimation :) ). This feature is particularly useful for empirical data analysis.

<!--
Please provide clear motivation for your patch and explain how it improves
Bitcoin Core user experience or Bitcoin Core developer experience
significantly:
* Any test improvements or new tests that improve coverage are always welcome.
* All other changes should have accompanying unit tests (see `src/test/`) or
functional tests (see `test/`). Contributors should note which tests cover
modified code. If no tests exist for a region of modified code, new tests
should accompany the change.
* Bug fixes are most welcome when they come with steps to reproduce or an
explanation of the potential issue as well as reasoning for the way the bug
was fixed.
* Features are welcome, but might be rejected due to design or scope issues.
If a feature is based on a lot of dependencies, contributors should first
consider building the system outside of Bitcoin Core, if possible.
* Refactoring changes are only accepted if they are required for a feature or
bug fix or otherwise improve developer experience significantly. For example,
most "code style" refactoring changes require a thorough explanation why they
are useful, what downsides they have and why they *significantly* improve
developer experience or avoid serious programming bugs. Note that code style
is often a subjective matter. Unless they are explicitly mentioned to be
preferred in the [developer notes](/doc/developer-notes.md), stylistic code
changes are usually rejected.

<!--
Bitcoin Core has a thorough review process and even the most trivial change
needs to pass a lot of eyes and requires non-zero or even substantial time
effort to review. There is a huge lack of active reviewers on the project, so

Once things upstream have stabilized a bit more (the `core-updates` branch was fairly recently merged), we could look at bumping to something newer.
Package updates:
(base) glibc 2.35 -> 2.39
binutils 2.38 -> 2.41
diffutils 3.8 -> 3.10
gawk 5.2.1 -> 5.3.0
git-minimal 2.45.2 -> 2.46.0
grep 3.8 -> 3.11
gzip 1.12 -> 1.13
linux-headers 6.1.106 -> 6.1.119
make 4.3 -> 4.4.1
xz 5.2.8 -> 5.4.5
CMake 3.30 becomes available.
Clang/LLVM 19 becomes available.
Could be used for #32764.

664657ed134365588914c2cf6a3975ce368a4f49 bugfix: disallow label for ranged descriptors & allow external non-ranged descriptors to have label (scgbckbone)
Pull request description:
Motivation:
* ranged descriptors MUST not be able to have label (current impl allows it)
* external non-ranged descriptor MUST be able to have label (current impl disallows it, **if** `internal=false` is provided via importdescriptor user data)
Repro steps:
* create blank wallet and import descriptors
* external has `label=test` (not internal)
```
conn = bitcoind.create_wallet(wallet_name=w_name, disable_private_keys=True, blank=True,
passphrase=None, avoid_reuse=False, descriptors=True)
descriptors = [
{
"timestamp": "now",
"label": "test",
"active": True,
"desc": "wpkh([0f056943/84h/1h/0h]tpubDC7jGaaSE66Pn4dgtbAAstde4bCyhSUs4r3P8WhMVvPByvcRrzrwqSvpF9Ghx83Z1LfVugGRrSBko5UEKELCz9HoMv5qKmGq3fqnnbS5E9r/0/*)#erexmnep",

},
]
r = conn.importdescriptors(descriptors)
print(r)
```
response:
```
[{'error': {'code': -8,
'message': 'Internal addresses should not have a label'},
'success': False,
'warnings': ['Range not given, using default keypool range']},
{'success': True,
'warnings': ['Range not given, using default keypool range']}]
```
But in above, ONLY external has a label.
If you remove `internal: False` from external descriptor import object - it will import no problem:
```
[{'success': True,
'warnings': ['Range not given, using default keypool range']},
{'success': True,
'warnings': ['Range not given, using default keypool range']}]
```
Even tho it should NOT, as the descriptor is ranged. Current implementation relies on checking user provided data to decide whether desc is ranged.

Pull request description:
This PR grabs some interesting bits from https://github.com/bitcoin/bitcoin/pull/29284 and fixes some edge cases in how block tiebreaks are dealt with.
## Regarding #29284
The main functionality from the PR was dropped given it was not an issue anymore, however, reviewers pointed out some comments were outdated https://github.com/bitcoin/bitcoin/pull/29284#discussion_r1522023578 (which to my understanding may have led to thinking that there was still an issue) it also added test coverage for the aforementioned case which was already passing on master and is useful to keep.
## New functionality
While reviewing the superseded PR, it was noticed that blocks that are loaded from disk may face a similar issue (check https://github.com/bitcoin/bitcoin/pull/29284#issuecomment-1994317785 for more context).
The issue comes from how tiebreaks for equal work blocks are handled: if two blocks have the same amount of work, the one that is activatable first wins, that is, the one for which we have all its data (and all of its ancestors'). The variable that keeps track of this, within `CBlockIndex` is `nSequenceId`, which is not persisted over restarts. This means that when a node is restarted, all blocks loaded from disk are defaulted the same `nSequenceId`: 0.
Now, when trying to decide what chain is best on loading blocks from disk, the previous tiebreaker rule is not decisive anymore, so the `CBlockIndexWorkComparator` has to default to its last rule: whatever block is loaded first (has a smaller memory address).
This means that if multiple same work tip candidates were available before restarting the node, it could be the case that the selected chain tip after restarting does not match the one before.
Therefore, the way `nSequenceId` is initialized is changed to:
- 0 for blocks that belong to the previously known best chain
- 1 to all other blocks loaded from disk

19273d0705fcd2fbde686bc3b5b2375f691e303d fuzz: set mempool options in wallet_fees (brunoerg)
Pull request description:
Some functions in `wallet/fees.cpp` (fuzzed by the wallet_fees target) depends on some mempool stuff - e.g. relay current min fee, smart fee and max blocks estimation, relay dust fee and other ones. For better fuzzing of it, it would be great to have these values/interactions. That said, this PR enhances the `wallet_fees` target by:
- Setting mempool options - `min_relay_feerate`, `dust_relay_feerate` and `incremental_relay_feerate` - when creating the `CTxMemPool`.
- Creates a `ConsumeMempoolMinFee` function which is used to have a mempool min fee (similar approach from `MockMempoolMinFee` from unit test).
- Mock `CBlockPolicyEstimator` - estimateSmartFee/HighestTagretTracket functions, especifically. It's better to mock it then trying to interact to CBlockPolicyEstimator in order to have some effective values due to performance.
Note that I created `FeeEstimatorTestingSetup` because we cannot set `m_node.fee_estimator` in `ChainTestingSetup` since fae8c73d9e4eba4603447bb52b6e3e760fbf15f8.

Pull request description:
### Summary
Users can encounter cases where script checks are unexpectedly enabled (e.g. after reindex, or when `assumevalid`/`minimumchainwork` gates fail). Without an explicit line, they must infer state from the absence of a message, which is incomplete and error-prone.
The existing "Assuming ancestors of block …" line does not reliably indicate whether script checks are actually enabled, which makes debugging/benchmarking confusing.
### What this changes
We make the initial **script-verification** state explicit and log **why** checks are enabled to avoid confusion.
* Always log the first script-verification state on startup, **before** the first `UpdateTip`.
* Flatten the nested `assumevalid` conditionals into a linear gating sequence for readability.
* Extend the functional test to assert the old behavior with the new reason strings.
This is a **logging-only** test change it shouldn't change any other behavior.
### Example output
The state (with reason) is logged at startup and whenever the reason changes, e.g.:
* `Disabling script verification at block #904336 (000000000000000000014106b2082b1a18aaf3091e8b337c6fed110db8c56620).`
* `Enabling script verification at block #912527 (000000000000000000010bb6aa3ecabd7d41738463b6c6621776c2e40dbe738a): block too recent relative to best header.`
* `Enabling script verification at block #912684 (00000000000000000001375cf7b90b2b86e559d05ed92ca764d376702ead3858): block height above assumevalid height.`
