Build replay state from synthetic block-index metadata so the test no longer discards committed wallet mints. Assert coin-group counts through removal and apply each block once.

Rechecked all four inline comments against a96bfe43 on 2026-09-28. Retiring the temporary single-input wallet path is reasonable for the post-H2 cleanup. Please clarify in the PR description that private-to-EX sends are being restored.
The EX partial-completion and ignored fee-subtraction findings remain valid. I corrected the fee comment's attribution: the checkbox was already enabled post-H2; removing the EX guard exposes the mismatch. I narrowed the historical-test comment to the specific H1/H2 coverage lost, and withdrew/resolved the regtest-override finding because rejecting H1>H2 is intentional and both overrides can be supplied together.
One additional EX issue remains at sendcoinsdialog.cpp:559-580: for a mixed send containing an EX recipient and a non-EX recipient with fee subtraction, the EX branch skips copying prepared amounts into realRecipients. The non-EX recipient is shown the requested amount even though the prepared payment is smaller and the total uses that smaller amount. Reconcile the prepared amounts before replacing the intermediate recipient.
I withdraw the earlier missing-intermediate-output remark as a separate bug finding. That branch is silent, but successful construction preserves the intermediate script and I have not established a normal path that reaches it. The confirmed stage-2 failure described inline is sufficient to justify explicit partial-completion handling.
The RPC migration note remains valid: spendsparksplit exists in the published v0.14.17.2, v0.14.18.0, and v0.14.18.1 sources. Please document its removal and migration to spendspark, which returns a single txid string instead of an array.
Validation: exact-head source/diff review and caller tracing. No GUI or functional tests were run for this re-review.

Removing this guard re-enables the existing two-stage path. Stage 1 is committed and the form cleared at lines 790-815 before stage 2 is prepared. With -spendzeroconfchange=0, AvailableCoins(..., true, ...) excludes the intermediate output until confirmation or an InstantSend lock, so the EX payment can fail after Spark funds have moved to a wallet-owned transparent address. Please retain the guard or make partial completion explicit, including the first-stage txid and recovery steps.

Clarified after re-review at a96bfe43: the checkbox was already enabled post-H2 in the base. Removing the private-to-EX guard in sendcoinsdialog.cpp makes this mismatch reachable again.
For a private send to an EX address, sendcoinsdialog.cpp:476 silently clears the recipient's fSubtractFeeFromAmount before either transaction is prepared. For an EX-only payment, the requested amount is therefore sent in full and both fees are funded on top despite the checked box. Please disable or reject fee subtraction for private-to-EX recipients, or implement it and show the resulting amount in confirmation.

Narrowed after re-review at a96bfe43: my statement that the remaining H1<H2 coverage was only one cover-set test was too broad. H1<H2 cases remain for cover-set binding, mempool eviction, Spark Names, and wallet behavior. This is a regression-coverage request, not a demonstrated consensus bug in this PR.
The specific coverage lost is the distinction between H1 and H2 for V1 input counts, unknown references, canonical group IDs, and exact reference sets. This replacement test sets H1=H2 and checks below both and at/above both; it cannot catch those rules being assigned to the wrong activation. The deleted historical-batch and reference tests did check relevant H1<=height<H2 behavior. Please preserve a focused block-validation case for that interval, where the H1 restrictions apply but the H2 group-ID/reference rules do not yet apply. Mainnet retains that historical interval (1355970 through 1370999).

src/qt/walletmodel.cpp:1471-1478
🎯 Functional Correctness | 🟠 Major | ⚡ Quick winAccept the pre-activation V1 transaction format.
CreateSparkSpendTransactioncreates a V1 transaction whenexpectedNextBlockHeightis belownSparkChaumV2StartBlock. The GUI then rejects that transaction because it requiresIsSparkSpendV2(). This causes pre-activation Spark sends to fail with “Unable to create a versioned Spark transaction.”Make the postcondition require V1 before activation and V2 at or after activation.
