In feature_assumevalid.py, we check that a modified block 102 is invalid
by asserting a message in the debug.log. However, this can
intermittently fail as exiting the assert_debug_log can occur before the
block has actually been validated, thus causing the test to fail as the
validation error message is not present in the chunk of the debug.log
being examined.
We can wait for the block to make an invalid chain tip to ensure that the log
line will be present.
e67a676df9 fix: uptime RPC returns 0 on first call (Lőrinc)
Pull request description:
### Problem
#34328 switched uptime to use monotonic time, but `g_startup_time` was a function-local static in `GetUptime()`, meaning it was initialized on first call rather than at program start.
This caused the first uptime RPC to always return 0.
### Fix
Move `g_startup_time` to namespace scope so it initializes at program start, ensuring the first `uptime()` call returns actual elapsed time.
### Reproducer
Revert the fix and run the test or alternatively:
```bash
cmake -B build && cmake --build build --target bitcoind bitcoin-cli -j$(nproc)
./build/bin/bitcoind -regtest -daemon
sleep 10
./build/bin/bitcoin-cli -regtest uptime
./build/bin/bitcoin-cli -regtest stop
```
<details>
<summary>Before (uptime is initialized on first call)</summary>
```bash
Bitcoin Core starting
0
Bitcoin Core stopping
```
</details>
<details>
<summary>After (first uptime call is in-line with sleep)</summary>
```bash
Bitcoin Core starting
10
Bitcoin Core stopping
```

Pull request description:
As [suggested here](https://github.com/bitcoin/bitcoin/pull/34416#discussion_r2745302958), a minor refactor of `PeerManagerImpl::BlockRequestAllowed()` to take reference parameter (instead of pointer). The motivation is to make the code safer, by minimizing the risk of null-dereference, and to be more consistent.
The change is local to the `PeerManagerImpl::BlockRequestAllowed()` class.

f0a046094e scripted-diff: refactor: CWallet::LoadWallet->PopulateWalletFromDB (David Gumberg)
Pull request description:
This PR is mostly a refactor which splits out logic used for creating wallets and for loading wallets, both of which are presently contained in `CWallet::Create()` into `CWallet::CreateNew()` and `CWallet::LoadExisting()`
The real win of this PR is that `CWallet::Create()` uses a very bad heuristic for trying to guess whether or not it is supposed to be creating a new wallet or loading an existing wallet:
370c592612/src/wallet/wallet.cpp (L2882-L2885)
This heuristic assumes that wallets with no `ScriptPubKeyMans` are being created, which sounds reasonable, but as demonstrated in #32112 and #32111, this can happen when the user tries to load a wallet file that is corrupted, both issues are fixed by this PR and any other misbehavior for wallet files which succeeded the broken heuristic's sniff test for new wallets.
It was already the case that every caller of `CWallet::Create()` knows whether it is creating a wallet or loading one, so we can avoid replacing this bad heuristic with another one, and just shift the burden to the caller.

Pull request description:
1. Remove a comment referencing a file that no longer exists in the codebase: `script_invalid.json`.
2. Fix a test that isn't implemented as intended. The idea is to test execution order by providing a signature that would cause script failure when parsed. An empty signature does not cause script failure in `CHECKMULTISIG`. Use `OP_1` for the second signature instead of `OP_0`.
3. Copy existing `STRICTENC` tests and change the flag to `DERSIG`. `DERSIG` is a consensus flag (unlike `STRICTENC`), so it'd be good to have dedicated test cases.
`script_tests` pass on my end.

02b5f6078d fees: make flushes log debug only (ismaelsadeeq)
Pull request description:
This is a simple PR that updates the flushing log to use debug-level logging under the estimatefee category. It also ensures the log consistently includes only the full file path.
The motivation behind this is that the "Flushed fee estimates to fee_estimates.dat." logs can become noisy; it's done after one hour, so hiding it in the debug estimatefee category seems reasonable.

7528d18796 ci: show more verbose ccache stats (will)
580e9eefe3 ci: bump CCACHE_MAXSIZE to 2G (will)
Pull request description:
Currently some CI jobs don't have great ccache hitrates which we should try to improve: https://willcl-ark.github.io/bitcoin-core-ci-stats/graph/ccache/
- bump ccache maxsize to 2GB in all jobs. We have 150GB shared cache to use, so this should be OK at maximum of 36GB total (current jobset).
- print more verbose ccache stats in the CI logs
The idea is that increasing the cache size to > 2x needed size should eliminate any cache thrashing which might be taking place on master builds when we save the cache. Additionally, larger caches result in more hits in general.

bf3b5d6d06 test: clarify getCoinbaseRawTx() comparison (Sjors Provoost)
78df9003d6 [doc] Update comments on dummy extraNonces in tests (Anthony Towns)
Pull request description:
This PR changes the Mining IPC interface to stop including a dummy `extraNonce` in the coinbase `scriptSig` by default, exposing only the consensus-required BIP34 height. This simplifies downstream mining software (including Stratum v2), avoids forcing clients to strip or ignore data we generate, and reduces the risk of incompatibilities if future soft forks add required commitments to the `scriptSig`.
Existing behavior is preserved for RPCs, tests, regtest, and internal mining by explicitly opting in to the dummy `extraNonce` where needed (e.g. to satisfy `bad-cb-length` at low heights), so consensus rules and test coverage are unchanged. The remainder of the PR consists of small comment fixes, naming clarifications, and test cleanups to make the intent and behavior clearer.

Pull request description:
This is a second slice carved out of #28792. It contains the following changes that are crucial for the embedding of asmap data which is added the following PR in the series (probably this will remain in #28792).
The changes are:
- Modernizes and simplifies the asmap code by operating on `std::byte` instead of bits
- Unifies asmap version calculation and naming (previously it was called version and checksum interchangeably)
- Operate on a `span` rather than a vector in the asmap internal to prevent holding the asmap data in memory twice
- Add more extensive documentation to the asmap implementation
- Unify asmap casing in implemetation function names
The first three commits were already part of #28792, the others are new.
The documentation commit came out of feedback gathered at the latest CoreDev. The primary input for the documentation was the documentation that already existed in the Python implementation (`contrib/asmap/asmap.py`) but there are several other comments as well. Please note: I have also asked several LLMs to provide suggestions on how to explain pieces of the implementation and better demonstrate how the parts work together. I have copied bits and pieces that I liked but everything has been edited further by me and obviously all mistakes here are my own.

Apply the fix from the issue to temporarily to treat this error as a
warning, until the upstream key can be updated.
This PR should be reverted once the upstream key is updated.
With 15 runners we get 150GB of cache space to use, and we currently
have 18 jobs using ccache.
Although each run only generates ~ 200-300 MB of cache data on each run,
the small the small size may be contributing to poor hitrate.
Bump ccache to 2GB per job ~ --> 36GB of the total 150GB cache space to
try and reduce any thrashaing and generally increase hitrate.
facb2aab26 test: Turn ElapseSteady into SteadyClockContext (MarcoFalke)
Pull request description:
`ElapseSteady` was introduced a while back, but is only used in one place. It makes more sense if this were a context manager, so that mocktime does not leak from one test into the next.
So turn it into a context manager, rename it and allow easy time advancement via e.g. `steady_ctx += 1h`.

3bd98b4508 refactor: use transparent comparator for setBlockIndexCandidates lookups (joaonevess)
Pull request description:
### Rationale
This PR improves code safety by removing a `const_cast` in `src/validation.cpp`.
Currently, `setBlockIndexCandidates` stores mutable `CBlockIndex*`. However, validation logic (like `CVerifyDB`) often holds `const CBlockIndex*`. Previously, checking for existence in the set required casting away constness. While currently benign, this bypasses compiler safety checks and could mask accidental modifications in future refactors.
### Description
1. **Enable Heterogeneous Lookup:** Added `using is_transparent = void;` to `CBlockIndexWorkComparator` in `src/node/blockstorage.h`. This allows the `std::set` to natively accept `const CBlockIndex*` for lookup (utilizing C++14 heterogeneous lookup).
2. **Remove Cast:** Removed the now unnecessary `const_cast<CBlockIndex*>` in `src/validation.cpp`, allowing the compiler to strictly enforce const-correctness.
### Notes
- **Refactoring only:** No behavioral change.
- **Verification:** `validation_tests` and `blockmanager_tests` pass.

51abf7d15b script: remove unused SCRIPT_ERR_LAST (Antoine Poinsot)
Pull request description:
It was introduced in ab9edbd6b6 and never used since. It seems it might have been intended to be exposed as part of a public library interface, which has since been superseded.
The only call site uses SCRIPT_ERR_ERROR_COUNT directly.

eeb4d28148 validation: follow-up nits for lock-free `IsInitialBlockDownload()` (Lőrinc)
Pull request description:
Innocent follow-up to #34253:
* Add `AssertLockHeld(cs_main)` to `ChainstateManager::UpdateIBDStatus()` given it's already annotated with `EXCLUSIVE_LOCKS_REQUIRED(cs_main)`.
* Fix outdated comment about constness of `ChainstateManager::IsInitialBlockDownload()` (compilation and build passes without it).
* And since we're touching it, we might as well mark `ChainstateManager::IsInitialBlockDownload()` as `noexcept` now.
