Final validation — Phase 2 only (queue backlog)
Verified the supplied findings against head 47be756 and independently reproduced both synthetic-wallet fixture assertion failures using the local executables. The x-only descriptor omission is explicitly documented in the backport commit and is not a blocking prerequisite gap, but the PR description's claim that every upstream hunk is present should reflect that exception.

- [BLOCKING] src/wallet/wallet.cpp:1534-1535: Adapt the remaining synthetic-block fixtures to the birthday filter
The birthday filter breaks two existing fixtures whose synthetic block times do not match their descriptor creation times. In `src/bench/wallet_create_tx.cpp`, descriptors are created at the current time, but `generateFakeBlock()` advances from genesis, so the funding blocks are skipped. Running `./src/bench/bench_dash -filter=WalletCreateTxUseOnlyPresetInputs -sanity-check` aborts at the balance assertion on line 107; both WalletCreateTx benchmarks use this setup. In `src/wallet/test/fuzz/notifications.cpp`, synthetic `BlockInfo` objects leave the new `chain_time_max` field at its default zero, so their transactions are also skipped. Feeding the ten-byte input `00000000010100000000` (hex) to `FUZZ=wallet_notifications ./src/test/fuzz/fuzz` aborts at the balance-conservation assertion on line 174.

Resolved (re-reviewed at d7ca2696): Your appended follow-ups fix both reported fixtures: wallet_notifications sets chain_time_max to the maximum, and WalletCreateTx sets genesis mocktime before descriptor creation. I also verified that the remaining availablecoins test callers import a timestamp-zero descriptor, so their synthetic blocks are not skipped.

Added the bitcoin#27907 fix: SetMockTime(chainman->GetParams().GenesisBlock().nTime) before the CWallet construction in both WalletCreateTx and AvailableCoins, so the descriptor creation time is below the synthetic block times and the balance assertions hold. The wallet_notifications half was already addressed by bitcoin#27786, which is on the branch. (folded into the bitcoin#27469 commit)

Re-review — Final validation — Phase 1 + Phase 2
Verified the complete diff at d7ca269 and independently reproduced a blocking regression: restoring an existing mnemonic before synchronization leaves historical funds undiscovered until an explicit rescan. The previous synthetic-block fixture issue is fixed, and both disputed upstream omissions are explicitly documented intentional exclusions. The daemon build, diff whitespace check, and syntax checks for the three changed Python files passed; the worktree remains unchanged.

The restored balance remains 0; rescanblockchain subsequently recovers 500 DASH. Previously, blockConnected scanned those arriving blocks. Give restored seeds a conservative persisted descriptor birthday, distinguish them from newly generated seeds, and add regression coverage for restoration before synchronization completes.

Same as above: the early return matches upstream exactly, and the restored-seed timestamp is set by Dash's SetupDescriptorGeneration, which this branch does not change; adding restored-vs-generated seed birthday semantics is new functionality outside the backport's scope.

Still applies (re-reviewed at fd929777): Author, byte-for-byte match does not clear the Dash-side birthday this new filter reads; verified still unhandled at head, so it stays open until restored seeds get a conservative birthday or equivalent guard.

Agreed — the release note for the unbackported importmempool RPC does not belong here; bitcoin#28637 is already absent from the current head (six commits, ending at bitcoin#27786), so nothing further is needed on the branch. bitcoin#28637 is not on this branch any more; nothing to do. 🤖 backportsys, on behalf of the Dash backport pipeline. |

The notifications.cpp half is already fixed on the branch by bitcoin#27786 (chain_time_max set to max). For the bench half I applied the upstream bitcoin#27907 hunks to src/bench/wallet_create_tx.cpp, mocking the clock to the genesis block time before the wallet is created in both WalletCreateTx and AvailableCoins. The x-only suggestion is a PR-description matter, not a code change. (folded into the 🤖 backportsys, on behalf of the Dash backport pipeline. |
bitcoin#27786 is present at the current head, but the bitcoin#27907 bench change was not — I applied it to src/bench/wallet_create_tx.cpp. Note Dash does carry the AvailableCoins benchmark in that file, so both upstream hunks were taken, not just the WalletCreateTx one.

blockConnected's birthday filter is byte-for-byte upstream bitcoin#27469; the reported gap comes from Dash's pre-existing mnemonic-restore path persisting GetTime() as the descriptor creation time, and giving restored seeds a distinct conservative birthday would be a new Dash-only wallet code path beyond this backport (a follow-up, not a backport error). 🤖 backportsys, on behalf of the Dash backport pipeline. |

⚠️ 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 hunks verify cleanly at head and both fixture follow-ups are present, but the new birthday filter exposes Dash's restore path which persists GetTime() for restored mnemonics, causing historical blocks arriving during IBD to be silently skipped. Commit-message provenance for the folded bench hunks is also missing.
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.

Verified at fd929777911: SetupDescriptorGeneration (scriptpubkeyman.cpp:2532) persists GetTime() for both fresh and restored (non-empty secure_mnemonic) seeds, AddScriptPubKeyMan (wallet.cpp:4323-4328) copies it into m_birth_time via FirstKeyTimeChanged, and blockConnected (wallet.cpp:1535) skips blocks with chain_time_max older than that birthday. On your byte-for-byte point: matching upstream text is not the issue — upstream has no mnemonic-restore path that mints a false birthday, so this branch newly activates a Dash-only failure. The existing upgradetohd ScanForWalletTransactions from genesis does not save the IBD case because it only covers the tip present at restore time; blocks downloaded after restore still hit the early return, and AttachChain's findFirstBlockWithTimeAndHeight(birthday - WINDOW) path likewise starts near the tip when birthday is now. Fix without touching the upstream hunk: persist a conservative birthday for the restored-seed branch in SetupDescriptorGeneration and add a restore-before-sync regression test.

Confirmed and agreed: upstream 82bb783 (bitcoin#27469) does not touch src/bench/wallet_create_tx.cpp, so those two SetMockTime(genesis) hunks come from bitcoin#27907 (a72af2e) and the fold should be disclosed.

should not be PR be paartial with mark "no taproot yet"?

Agreed, this is a partial backport: Dash has no taproot (XOnlyPubKey only exists as a forward declaration, and there are no tr() descriptors), so upstream's raw x-only pubkey type was dropped and KEY_TYPES_COUNT went 6->5. I added a note at the KEY_TYPES_COUNT definition spelling that out; the merge subject/PR listing should likewise carry the '(partial)' marker, which I can't set from here since it lives in the commit message.

Your quote from JSONRPCRequest::parse is exactly why the backport waits on "Received a POST request for / from" instead of upstream's "ThreadRPCServer method=getblocktemplate": Dash never logs that line for getblocktemplate. The bench line you saw ("HTTP RPC request handled: ... command=getblocktemplate") is emitted in ~RpcHttpRequest, i.e. only once the request completes, so it can never fire for a longpoll that is still blocking and cannot be used as the wait condition; inside the with block only the longpoll thread issues a request, so the HTTP line is unambiguous.

…g target BACKPORT NOTE: Dash adaptations: - src/test/fuzz/descriptor_parse.cpp: dropped the raw x-only pubkey key type (KEY_TYPES_COUNT 6->5, removed IdIsXOnlyPubKey() and its branch in Init(), renumbered IdIsConstPrivKey/IdIsXpub/IdIsXprv to 2/3/4) because Dash has no taproot and no XOnlyPubKey type; the doc comment was updated to match ---- that's why PR is partial until taproot is implemented - src/test/fuzz/descriptor_parse.cpp: kept Dash's existing `#include <key.h>` and `#include <script/standard.h>` (not present upstream at this commit) and added `#include <key_io.h>` as upstream does - src/test/fuzz/descriptor_parse.cpp: kept `SelectParams(CBaseChainParams::MAIN)` instead of upstream's `SelectParams(ChainType::MAIN)`/`#include <util/chaintype.h>`; Dash has not backported the ChainType enum (bitcoin#27491) ----- 131314b fuzz: increase coverage of the descriptor targets (Antoine Poinsot) 90a2474 fuzz: add a new, more efficient, descriptor parsing target (Antoine Poinsot) d60229e fuzz: make the parsed descriptor testing into a function (Antoine Poinsot) Pull request description: The current descriptor parsing fuzz target requires valid public or private keys to be provided. This is unnecessary as we are only interested in fuzzing the descriptor parsing logic here (other targets are focused on fuzzing keys serializations). And it's pretty inefficient, especially for formats that need a checksum (`xpub`, `xprv`, WIF). This introduces a new target that mocks the keys as an index in a list of precomputed keys. Keys are represented as 2 hex characters in the descriptor. The key type (private, public, extended, ..) is deterministically based on this one-byte value. Keys are deterministically generated at target initialization. This is much more efficient and also largely reduces the size of the seeds. TL;DR: for instance instead of requiring the fuzzer to generate a `pk(xpub6DdBu7pBoyf7RjnUVhg8y6LFCfca2QAGJ39FcsgXM52Pg7eejUHLBJn4gNMey5dacyt4AjvKzdTQiuLfRdK8rSzyqZPJmNAcYZ9kVVEz4kj)` to parse a valid descriptor, it just needs to generate a `pk(03)`. Note we only mock the keys themselves, not the entire descriptor key expression. As we want to fuzz the real code that parses the rest of the key expression (origin, derivation paths, ..). This is a target i used for reviewing bitcoin#17190 and bitcoin#27255, and figured it was worth PR'ing on its own since the added complexity for mocking the keys is minimal and it could help prevent introducing bugs to the descriptor parsing logic much more efficiently.
