P2 Badge Guard the first disk-read average against zero blocks

On the first ConnectTip invocation after process start, num_blocks_total is still zero because it is incremented only by the subsequent ConnectBlock call. This average is calculated before that call, so enabling benchmark logging emits inf or nan for the first disk-read per-block value and corrupts collected timing output; omit the average until the counter is nonzero or account for the current sample. The pre-change code explicitly avoided an aggregate here for this reason.

Review Change Stack

Walkthrough

The change centralizes block assembler options and adds a mempool package-assembly benchmark. PSBT analysis and signing now verify finalized inputs. Validation and operational timing use steady-clock durations. Wallet fee accounting uses transaction output totals, and wallet resend scheduling uses NodeClock. Wallet migration returns the reloaded wallet. Functional tests add PSBT coverage and update test framework behavior.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟠 High · up to bb610

This backport still contains unresolved PSBT memory-safety and resource-usage risks, along with wallet migration error-handling and test failures that can affect node reliability or hide incorrect behavior. These issues should be fixed before merge.

P2 Badge Return false for invalid finalized PSBT inputs

When a PSBT contains a nonempty but invalid final_script_sig and a matching non_witness_utxo, this check fails and execution falls through to FillSignatureData(), which marks the signature data complete; ProduceSignature() then immediately returns true without re-verifying it. Consequently FinalizePSBT/finalizepsbt can report completion and extract a transaction whose input script fails verification, while AnalyzePSBT labels the input ready for the finalizer. Keep the outer PSBTInputSigned(input) check and return the verification result for already-final inputs instead of falling through.

Preliminary review — Codex only

The partial PSBT backport still accepts invalid finalized scripts because failed verification falls through into signing code that trusts the existing final script; this defeats the backport's primary safety goal and blocks merge. Two lower-severity Dash integration issues also remain: the timing conversion resurrects a disk-read aggregate previously removed by bitcoin#27673, and the miner helper documents an option Dash does not expose.
Source: reviewer evidence from codex-general, codex-backport-reviewer, codex-dash-core-commit-history, Claude (empty finding set), and CodeRabbit; final verifier backend: Anthropic Claude Agent SDK (the supplied evidence does not expose exact backend model IDs). openclaw-agent/cliproxy/gpt-5.6-sol is orchestration-only and is not reviewer evidence.

Validated blockers were found in the Codex precheck. Opus is deferred until a fresh Codex revalidation clears the blocker gate.

In `src/psbt.cpp`:
- [BLOCKING] src/psbt.cpp:269-271: Reject invalid finalized PSBT inputs instead of trusting them during signing
  When `PSBTInputSignedAndVerified()` rejects a nonempty invalid `final_script_sig`, `SignPSBTInput()` falls through to `PSBTInput::FillSignatureData()`. That function copies the finalized script and marks `sigdata.complete`, so `ProduceSignature()` immediately returns true without executing the script. `FinalizePSBT()` and `FinalizeAndExtractPSBT()` can therefore report completion and extract an invalid transaction, while `AnalyzePSBT()` can classify the input as ready for finalization. Preserve the ability to construct valid empty scripts, such as the new OP_TRUE case, by falling through only when no finalized field exists; an already-finalized input must return the verification result.

In `src/validation.cpp`:
- [SUGGESTION] src/validation.cpp:3122-3127: Retain bitcoin#27673's single-duration disk-read log
  The merge base already contains bitcoin#27673, which removed the aggregate disk-read metric because `num_blocks_total` can still be zero before the following `ConnectBlock()` call. This backport resurrects `time_read_from_disk_total` from the older bitcoin#26118 context and divides it by that zero counter, producing `inf` or `nan` on the first applicable call. Remove the accumulator declared near line 3043 and retain the base's single-duration log, converting only the current interval with `Ticks<MillisecondsDouble>(time_2 - time_1)`.

In `src/node/miner.h`:
- [NITPICK] src/node/miner.h:231: Document Dash's block-size option in the miner helper
  `ApplyArgsManOptions()` reads `-blockmaxsize`, and that is the option registered by Dash. The copied upstream comment instead names `-blockmaxweight`, which is not configured in this tree. Adapt the comment to the Dash option name.

Final validation — Codex/Sol only (Phase 2 disabled)

At exact head 1c95a5d, the disk-read timing regression and incorrect miner-option documentation from the prior review are fixed. No in-scope blocker or suggestion remains; the finalized-PSBT fallthrough and tracepoint unit mismatch are real inherited upstream behaviors that should be handled separately rather than by diverging this backport.
Source: reviewer backend gpt-5.6-sol (Codex); the Claude reviewer backend's exact model ID was not supplied; final verifier backend Anthropic Claude Agent SDK (exact model ID not exposed). openclaw-agent/cliproxy/gpt-5.6-sol is orchestration-only and not reviewer evidence.

Validated zero-blocker Codex/Sol precheck evidence was promoted to final because Phase 2 (Sonnet/Opus) is temporarily disabled. This is Codex/Sol-only final validation, not Codex + Sonnet/Opus coverage.

Review provenance

  • Codex reviewers: gpt-5.6-sol — general (completed), gpt-5.6-sol — dash-core-commit-history (completed), gpt-5.6-sol — backport-reviewer (completed)
  • Verifier: gpt-5.6-sol — verifier
  • Sonnet/Opus: not run (Phase 2 disabled — temporary Codex/Sol-only final)

798430d wallet: Sanity check fee paid cannot be negative (Andrew Chow)
c1a84f1 wallet: Move fee underpayment check to after fee setting (Andrew Chow)
e5daf97 wallet: Rename nFeeRet in CreateTransactionInternal to current_fee (Andrew Chow)

Pull request description:

  Currently the fee underpayment check occurs right after we calculate what the transaction's fee should be. However the fee paid by the transaction at that time does not always match. Notably, when doing SFFO, the fee paid at that time will almost always be less than the fee required, which then required having a bypass of the underpayment check that results in SFFO payments going through when they should not.

  This PR moves the underpayment check to after fees have been finalized so that we always check whether the fee is being underpaid. This removes the exception for SFFO and unifies this behavior for both SFFO and non-SFFO txs.

Pull request description:

  Performance of block template building matters as miners likely want to be able to start mining on a block with transactions asap after a block is found. We would want to know if a mempool PR accidentally caused, for example, a 100x slowdown. An `AssembleBlock()` bench exists, but it operates on a mempool with 101 transactions, each with 0 ancestors or descendants and with the same fee. Adding a bench with a more complex mempool is useful because (1) it's more realistic (2) updating packages can potentially cause the algorithm to take a long time.

The second input of the extractor vector is a P2SH-P2WSH spend: its
UTXO and signatures are carried in witness_utxo and final_scriptwitness
fields, which Dash's PSBT implementation stores as unknown key-value
pairs, so the input can never be script-verified. The vector extracts
today only because PSBT finality is judged by final_script_sig being
non-empty, and it contradicts the finalizer vector, which was already
dashified to expect this input to stay unfinalized. Once finality is
checked by actual script execution (bitcoin#25595), extraction of this
vector must fail, so drop it. The extractor loop in rpc_psbt.py is kept
to preserve the upstream file structure.
… fields being empty

BACKPORT NOTE:
witness-scenario is omitted for backport; the new test provides the OP_TRUE prevout as non_witness_utxo, since Dash's PSBT has no witness_utxo field, and the expected hex is computed because the input spends a real prev-tx.
The segwit-based extractor vector was removed from rpc_psbt.json in a preceding commit, since its final scriptSig can no longer be script-verified.

e133264 Add test for PSBT input verification (Greg Sanders)
d256992 Verify PSBT inputs rather than check for fields being empty (Greg Sanders)

Pull request description:

  In a few keys spots, PSBT finality is checked by looking for non-empty witness data.

  This complicates a couple things:
  1) Empty data can be valid in certain cases
  2) User may be passed bogus final data by a counterparty during PSBT work happening, and end up with incorrect signatures that they may not be able to check in other contexts if the UTXO doesn't exist yet in chain/mempool, timelocks, etc.

  On the whole I think these heavier checks are worth it in case someone is actually assuming the signatures are correct if our API is saying so.

…26695

6a5e88e miner: don't re-apply default Options value if argument is unset (stickies-v)
ea72c3d refactor: avoid duplicating BlockAssembler::Options members (stickies-v)
cba749a refactor: rename local gArgs to args (stickies-v)

Pull request description:

  Two follow-ups for bitcoin#26695, both refactoring and no observed (*) behaviour change:
  - Rename `gArgs` to `args` because it's not actually a global
  - Add `BlockAssembler::Options` as a (private) member to `BlockAssembler` to avoid having to assign all the options individually, essentially duplicating them

  Reduces LoC and makes the code more readable, in my opinion.

  ---

  (*) as [pointed out by ajtowns](bitcoin#26883 (comment)), this PR changes the interface of `ApplyArgsManOptions()`, making this not a pure refactoring PR. In practice, `ApplyArgsManOptions()` is never called in such a way that this leads to observed behaviour change. Regardless, I've carved out the potential behaviour change into a separate commit and would be okay with dropping it, should it turn out to be controversial.

1114-1115: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Create a fresh options dictionary for walletcreatefundedpsbt.

options still contains "add_to_wallet": True from the preceding send case at Lines 1092-1093. The walletcreatefundedpsbt options contract in src/wallet/rpc/spend.cpp does not define add_to_wallet, so this call is rejected before Case (3) runs. Use options = {"add_inputs": True} here.

Proposed fix
-        options["add_inputs"] = True
+        options = {"add_inputs": True}
         assert "psbt" in wallet.walletcreatefundedpsbt(outputs=[{addr1: 8}], inputs=inputs, options=options)

Propagate post-migration reload failures.

LoadWallet returns nullptr when the migrated wallet cannot be reloaded. This branch still returns res as a successful MigrationResult, with a null MigrationResult::wallet and the reload error discarded. Check res.wallet after Line 4995 and return util::Error{error} or perform the documented recovery.
