`TransactionConfirmationUnknown` told the user a payment might already be on the network but discarded the one thing that could later settle the question. `send_payment` holds the signed transaction at the failure site, so the id now rides along on the error; the upstream orchestrators that build and broadcast their funding transaction internally surface `None`, which states the boundary in the type instead of a comment. Also routes `create_asset_lock_proof` through the same classifier. It mapped every broadcast failure to the generic wallet-backend envelope, whose "please retry in a moment" is exactly the double-spend advice #961 set out to eliminate — upstream keeps both the UTXO reservation and the resumable Built row when that broadcast is ambiguous, so the retry it invited could not have gone through anyway.

…pshot DET has event-sourced every status upgrade since the platform-wallet migration, but nothing could ask the store about one specific transaction outside a `#[cfg(test)]` seam. `transaction_confirmation` answers "did that payment land?" off the already-published display snapshot, so the answer can never disagree with the history row the user is looking at. The reply pairs the status with the block height that backs it: dash-spv injects a broadcast transaction into its own mempool before any peer verdict, so presence proves nothing and a mined tier without a height is not evidence a caller should spend a funds message on.

…kes it A payment whose broadcast came back unverified left the user holding a "wait a moment, then refresh" banner and no way to learn the answer except by checking by hand. The app already knew: every status upgrade has been event-sourced into the display snapshot since the platform- wallet migration. Nobody was asking the question on the user's behalf. `PendingConfirmation` adopts that banner and watches the snapshot for its transaction to reach an InstantSend lock or a mined block, then replaces it with a plain confirmation. It sits beside the other per-frame reconcilers rather than in `SendScreen`, because the watch has to outlive navigating away from Send. Presence in the snapshot is deliberately not the predicate: dash-spv injects a broadcast transaction into its own mempool before any peer verdict, so an `Unconfirmed` row appears even for one no peer accepted. A mined tier without a block height is refused for the same reason — a funds message deserves evidence, not a tier. No failure verdict is ever synthesised. Modern Dash Core has no rejection signal on the wire, so an invalid transaction and a slow one look identical; a timeout dressed up as "failed" would eventually tell someone their money was safe to send again when it was not. Instead the copy changes once at eleven minutes — a full dash-spv rebroadcast cycle plus several block windows — to point at the transaction-history row, which tracks the same data live. The watch continues, so a late confirmation still has the last word. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Nagatha's architecture plan flagged one genuine open risk (R-1): whether a locally-injected, never-relayed transaction could appear at a Confirmed tier in DET's snapshot without a real network verdict, which would let the new pending-confirmation banner falsely confirm a payment that never landed. No funded testnet wallet was available to close it during implementation. Adds a docs/gui-testing scenario to run before this PR leaves draft, and a TODO pointing at it from the code-side mitigation (network_took_transaction's height.is_some() guard). Also folds in R-4 (does the watch resolve for a purely-outgoing send with no wallet-owned change output?). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

📝 WalkthroughWalkthroughThe change adds transaction confirmation lookup and pending-payment monitoring. Ambiguous payment broadcasts carry a transaction ID to the application.

Preliminary review — Codex only
The transaction-ID propagation and snapshot confirmation predicate are well structured, but the new reconciler has three funds-status blockers: shared banner handles can erase unresolved warnings, late task results can be attached to the wrong network, and the stale message asserts history state that the snapshot does not establish. These issues must be fixed before the automatic confirmation flow can reliably report each payment's outcome.

- [BLOCKING] src/app/reconcilers.rs:909-918: Keep banners independent across watched transactions
`MessageBanner::set_global` deduplicates identical text and returns handles containing the same key, while every ambiguous transaction uses the same message. If two watches share that key and one confirms, this branch clears the only ambiguous banner even though the other watch remains unresolved with a handle to a nonexistent banner. `raise_stale` has the same problem for stale warnings, and eviction clears the shared ambiguous banner for all retained watches; a txid-less ambiguous operation can also lose its warning when a watched payment resolves. Give each transaction independent banner identity, or manage one aggregate banner whose lifecycle and wording account for every unresolved watch, and add a mixed-verdict regression test with simultaneous transactions.
In `src/app.rs`:
- [BLOCKING] src/app.rs:2899-2903: Bind late confirmation watches to their originating network
`handle_backend_task_with_context` runs the task against the `AppContext` captured at dispatch, but `BackendTaskContext::Other` does not retain that context's network. If a payment dispatched on one network returns `TransactionConfirmationUnknown` after the user switches networks, `finalize_network_switch` has already reset the old watches and this arm creates a new watch on the active network. Subsequent polls inspect the wrong wallet snapshot, so the original transaction cannot resolve and the active network eventually shows an unrelated stale warning. Preserve the originating network in the result or watch, then either reconcile through that network's cached context or suppress the completion when it no longer matches `chosen_network`.
- [BLOCKING] src/app.rs:830: Do not claim every stale watch has a Pending history row
`pending_step` becomes stale for every non-accepted observation, including `None` and a `Confirmed` or `ChainLocked` record without a height. The snapshot API defines `None` as no loaded wallet having seen the transaction, so no history row is guaranteed; records in the latter states render as Confirmed or ChainLocked rather than Pending. The banner therefore states both an outcome and a visible history status that the app cannot establish. Keep the wording at the same uncertainty level as the available evidence and direct the user to the sending wallet without promising that a Pending row exists.
Three review findings on the auto-reconcile banner, all living in the same handful of lines. Every ambiguous-outcome banner is literally one banner: `set_global` keys them by exact text, and each watch raised the same `TransactionConfirmationUnknown` copy. The first verdict — confirmed, gone stale, or evicted at the cap — therefore cleared the message out from under every other payment still waiting, and out from under the identity and asset-lock outcomes, which carry no transaction id and share that text. `PendingConfirmation` now owns the two banners instead of each watch holding a handle, and retires one only once nothing still speaks through it. A late "outcome unknown" carried no network. `CoreTask::SendWalletPayment` fell through to `BackendTaskContext::Other`, so an error arriving after a network switch opened a watch against the network now selected, whose snapshot has never heard of the transaction: it could only go stale and then hand the user transaction-history advice for the wrong wallet. The context records the network at dispatch instead — the task cannot name it itself, as a `Wallet` carries no network and its extended public key cannot tell Devnet or Regtest from Testnet — and a mismatch keeps the banner without opening a watch. The DashPay contact send broadcasts inside its own task, so it is stamped there too. The stale copy claimed the transaction "is listed as Pending in this wallet's transaction history". That copy is reached for any observation that is not a confirmation, including one no loaded wallet has seen at all — no history row to be listed in — and a mined tier with no block height, which the wallet would render under another word entirely. It now says only what the app can check. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Preliminary review — Codex only
The network-attribution and stale-wording changes fix two prior blockers, and the aggregate ownership model prevents direct clearing of a banner still needed by another transaction. One blocking lifecycle bug remains: capacity eviction can remove a required ambiguous or stale warning while the reconciler retains a dead handle and therefore never recreates the warning.

- [BLOCKING] src/app/reconcilers.rs:975-990: Keep banners independent across watched transactions
(existing thread: https://github.com/dashpay/dash-evo-tool/pull/964#discussion_r3871394613)
`sync_banners` treats `self.ambiguous.is_some()` and `self.stale.is_some()` as proof that the corresponding banner still exists, but a `BannerHandle` remains stored after `MessageBanner::set_global` evicts its banner at the five-banner capacity. For example, if the shared ambiguous warning is followed by four persistent banners, confirming one of two watched payments adds the success banner at line 976 and evicts the still-needed ambiguous warning. The sibling watch remains unresolved, but later polls retain the dead `ambiguous` handle and cannot recreate its warning. An evicted stale warning has the same permanent-loss path. Track actual banner presence or prevent these funds-status banners from being capacity-evicted, and cover the mixed-verdict case with a capacity-bound regression test.
…e-broadcast-status
…screen The global banner list shows five messages at once and evicts the oldest to make room. PendingConfirmation held a BannerHandle for the ambiguous-outcome and stale-advice banners and treated `is_some()` as proof they were still on screen — but a handle outlives its banner. Four unrelated notifications during a wait (connection, migration, a per-task success) silently pushed the "your payment was sent but could not be verified" warning out, `sync_banners` kept believing it was showing, and the user lost the one message telling them not to send again until a network switch or restart. `is_some()` cannot answer this, and neither can mere absence: a banner the user dismissed is also absent, and resurrecting that one would turn a warning they have already read into a nag they cannot close. MessageBanner now records the keys it drops at capacity, so BannerHandle::was_evicted() separates "the cap took it" from "someone closed it". sync_banners re-raises only on the former. Restoring the ambiguous banner needs its copy, which originates in the error arm; PendingConfirmation captures it from the handle at adopt time via BannerHandle::text() rather than being told it separately, so the restored message is byte-identical to the one displayed. A restored banner loses only its collapsible technical details, which are diagnostic and already logged. The poll loop also returned early whenever no watch was open, so a claim with no transaction id to watch — identity registration, top-up, Platform-address funding, asset locks — had nothing ticking to notice its banner had gone. That claim is the one no verdict can ever answer, which made the loss permanent. It now ticks for its banner alone. Regression tests cover eviction and restoration of each banner, both together on a mixed verdict, the watchless claim, and dismissal staying dismissed.

Preliminary review — Codex only
The aggregate reconciler, network attribution, and intentional handling of transaction-ID-less outcomes are correct at the exact head. One blocking lifecycle defect remains: bounded eviction history can forget a required payment warning before reconciliation, leaving the unresolved warning permanently absent in violation of SND-018.

In `src/ui/components/message_banner.rs`:
- [BLOCKING] src/ui/components/message_banner.rs:18-21: Keep banners independent across watched transactions
Eviction attribution expires after `EVICTED_KEY_MEMORY` entries even though a `BannerHandle` can remain owned by `PendingConfirmation` indefinitely. Starting with an unresolved payment banner, 25 distinct notifications are enough to evict that banner and then perform 20 further evictions, removing its key from the history. `AppState::update` drains all queued task results before calling `pending_confirmation.update`, so this entire sequence can occur before `sync_banners` inspects the retained handle; it can also occur while the two-second poll throttle suppresses synchronization. The handle is then not live, but `was_evicted()` permanently returns false, so the ambiguous or stale warning is never recreated despite the unresolved claim. Preserve the lifecycle cause for as long as the handle exists—for example, through state shared by `BannerState` and `BannerHandle` that records eviction versus dismissal—or otherwise make eviction attribution durable, and add a regression test that exceeds `EVICTED_KEY_MEMORY` before reconciliation.
Eviction attribution lived in a bounded log of recently-dropped banner keys held in egui context data. A handle whose banner was evicted, and then outlived twenty further evictions, aged out of that log: was_evicted turned permanently false even though the handle was still held and the banner still gone. PendingConfirmation gates its re-raise on exactly that answer, so an unresolved payment warning could be lost for good. The window is real — AppState::update drains every queued task result before the reconciler ticks, and the two-second poll throttle can suppress a tick for longer still, so a burst of unrelated notifications fits between the eviction and the question. Move the cause onto the banner itself: a flag shared by BannerState and every BannerHandle naming it, set when the cap drops the banner. It lives exactly as long as someone can still ask, so no amount of later churn can forget it, and the bounded log goes away. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The reconciler raised the confirmation with a bare `set_global` on `MessageType::Success`, which carries the default five-second auto-dismiss, and dropped the handle. `sync_banners` retires the persistent ambiguous warning on the very same tick, and the frame loop schedules an unconditional repaint every second, so the timer ran with nobody watching: roughly six seconds after the network took the payment the screen was blank again. That inverts the point of the feature. The watch exists precisely because the user walked away — SND-018 has it surviving the Send screen, and the manual scenario tells the tester to navigate away before the verdict lands. Someone who stepped out came back to no warning and no confirmation, worse off than before the watch existed, when the warning at least had auto-dismiss disabled and stayed put. Hold the confirmation in the reconciler alongside the two banners it already owns and raise it through `raise_persistent`, so the answer to a funds question is exactly as durable as the question was, and drop it on a network switch for the same reason the watches are dropped. The existing confirmation test never advances the clock, so it could not see this. The new test asserts on the countdown annotation a banner renders only while a dismiss timer is pending, which pins the timer's absence without waiting five seconds; a control case on an ordinary Success banner keeps that assertion honest if the annotation changes. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Three defects around the same warning, all found reviewing the watch that raises it. `update()` returned before `sync_banners` whenever the wallet backend was not wired yet, so no evicted warning was restored during boot or a network switch — and `last_poll` had already been stamped, putting the next attempt a full interval away. Those are precisely the windows that flood the banner list with startup, migration and connection messages, so the restore was missing exactly when it was needed most. Restoring a banner needs no snapshot, and the `watches.is_empty()` branch three lines above already proved the two are separable. `apply()` reconciled the banners and only then raised the confirmation. Raising evicts the oldest entry once the list is full, so the confirmation could knock out the warning that `sync_banners` had restored one statement earlier, leaving it to blink back two seconds later. Raise first and reconcile last, so a full list costs the message that reassures rather than the one that guards the user's money. `transaction_confirmation_any` ranked candidates on status alone. The reader's evidence test demands a height at the mined tiers, and iteration order over the snapshot map is arbitrary, so two copies at the same status could hand back the height-less one and read as "not confirmed yet" while the evidence sat in the other wallet's history. Unreachable today, since status and height are set together, but the guard exists precisely because a mis-tiered record is anticipated. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`a_dismissed_banner_is_not_reported_as_evicted` put its question to an `Option` it had just emptied. `Option::was_evicted` is `is_some_and(..)`, so a `None` answers `false` whatever the eviction machinery does — the test passed with the ledger intact, and would pass just as happily with it deleted outright. That guard is not incidental. It is the one asserting that restoring an evicted message does not also resurrect one the user deliberately closed, which is the difference between a banner that comes back and a banner nobody can get rid of. It has been inert since it was written. Keep a cloned handle as a live witness across the dismissal and ask that instead, plus assert the dismissal really did take the banner off the list so the second question is not answered by an absent premise. Confirmed the test now fails as intended by reducing `was_evicted` to `!is_live()` — the naive reading it exists to rule out. Uses only `Clone`, `is_live` and `was_evicted`, which are unchanged in both the key-log and the shared-flag shape of this module, so the body stands whichever lands. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`PENDING_CONFIRMED_MESSAGE` was the fixed singular "Your transaction is confirmed." `apply()` collapsed every confirmation in a tick into one bool and raised one banner from it, and `set_global` dedupes by exact text, so any number of confirmed payments produced a single message that named none of them. The feature is built for concurrency — `MAX_PENDING_WATCHES` is 8, and SND-018 promises that answering one payment leaves the others' warnings standing. It delivers that for the warning. The answer had no subject. A user with two payments in limbo saw an unattributed confirmation beside an unattributed "could not be verified", with nothing to say which was which: read it against the wrong payment and they resend one that already landed, read the surviving warning as stale and they resend the other. Both pay the same person twice, which is the outcome the watch exists to prevent. Give each resolved watch its own banner naming its transaction. The id is shortened through `shorten_id`, already used on hex elsewhere, so the head and tail still match by eye against the full id in the transaction history the stale copy sends the user to. CLAUDE.md § Error messages rule 6 admits identifiers into user copy for exactly this purpose, and the sentence stays one i18n unit with the id as a placeholder. Confirmed both new assertions fail against the old shared string: the copy test on two ids collapsing to one message, and the two-watch test on the confirmation being readable as the payment still in the air. Amount and recipient would read better than an id, but neither is plumbed through `track` today; that stays open. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Keep confirmation results available after banner-cap eviction.
These handles only allow cleanup during reset. When five later unique banners arrive, MessageBanner evicts an older confirmation. sync_banners never restores confirmation banners, so a user who returns later can lose the answer even though this flow marks it persistent. Store enough confirmation state to restore an evicted result without restoring a manually dismissed one, or present durable confirmations outside the capacity-bound banner list.

Preliminary review — Codex only
The shared per-banner lifecycle state fixes the prior bounded eviction-attribution defect, and both targeted long-burst regressions pass. Two in-scope blockers remain: confirmation answers can still be lost to the five-banner capacity, and no-change outgoing payments cannot observe an InstantSend lock through the snapshot event seam.

- [BLOCKING] src/app/reconcilers.rs:1027-1031: Keep confirmed answers from being evicted before the user sees them
Disabling auto-dismiss does not exempt these confirmation banners from `MessageBanner`'s five-banner capacity. The reconciler can resolve all eight allowed watches in one poll; after the ambiguous banner and later confirmations fill the list, the remaining confirmations evict the first three before the next render. A single confirmation can likewise be evicted by five later unrelated notifications. `sync_banners` restores only ambiguous and stale warnings, and after all watches resolve `update` takes its idle path, so the dead handles retained in `self.confirmed` never recreate the answers. Those handles also accumulate indefinitely as confirmations are dismissed or evicted. Store each confirmation's transaction and lifecycle state so capacity eviction can be restored without overriding manual dismissal, or move confirmed outcomes to a capacity-safe durable surface. Add a regression that resolves more than `MAX_BANNERS` watches before rendering and another that evicts one confirmation with unrelated notifications.
- [BLOCKING] src/app/reconcilers.rs:982-991: Observe InstantSend locks for payments with no change output
This polling path can learn about an InstantSend lock only through the published wallet snapshot, but the pinned upstream event path does not publish that update for a purely outgoing transaction with no wallet-owned output. At rust-dashcore revision `3d13d983`, `mark_instant_send_utxos` rewrites the transaction record but returns `true` only when an owned UTXO for the transaction was marked; `key-wallet-manager::process_instant_send_lock` emits `WalletEvent::TransactionInstantLocked` only for wallets where that return value is true. A no-change send owns no output from its transaction, so DET's `EventBridge` receives no event, never invokes `SnapshotStore::mark_instant_locked`, and does not republish the updated record. The watch therefore remains `Unconfirmed` until a block arrives even after the network supplied an InstantSend lock, missing one of this PR's stated confirmation outcomes and the explicitly documented no-change live scenario. Update the upstream event contract or provide another acceptance signal that covers outgoing no-change transactions, with a regression for that transaction shape.

TL;DR
When a payment's confirmation couldn't be verified, the app used to tell you to wait and check your balance yourself — and then never mention it again. Now it keeps watching that payment on your behalf and tells you the real outcome once the network actually decides: a plain "Your transaction is confirmed." the moment it lands, or a pointer to your transaction history if it's still unconfirmed after a while. You never have to go looking for the answer.
User story
As a user who just sent a payment that came back with an unverifiable confirmation, I want the app to tell me the real outcome once it's known, so that I don't have to manually check my balance or transaction history to find out whether my money moved.
Scenario
Actual behavior (before this PR, since #961): the app shows "Your transaction was sent but the confirmation could not be verified. Wait a moment, then refresh your balance before sending it again." — and then says nothing further, ever. The user has to notice the message, remember to go check, and interpret the transaction history themselves.
Expected behavior (after this PR): the app keeps watching that specific payment in the background. The moment the network takes it (an InstantSend lock, or a mined block), the message is replaced with "Your transaction is confirmed." — no action needed. If it's still unconfirmed after eleven minutes, the message changes once to point at the transaction history and warn against sending again in the meantime; the watch keeps going, so a later confirmation still resolves it correctly. The app never claims a payment failed — the Dash network has no way to say that, and guessing would risk telling someone it's safe to resend when it isn't.
This PR also closes a gap #961 missed: creating an asset lock (used by identity registration/top-up funding) still gave the old "please retry" advice on the same kind of ambiguous outcome. That's fixed here too.
Detailed discussion
Follow-up to #961, which fixed the wording of the ambiguous-broadcast error but left the app permanently dead-ending on it. This closes the loop with the mechanism DET already had rather than building new plumbing:
TaskError::TransactionConfirmationUnknownnow carries anOption<Txid>—Someon the one path where the broadcasting code holds the id locally (WalletBackend::send_payment, which also covers DashPay "send to contact" — same code path),Noneon the upstream orchestrators (identity registration/top-up, platform-address funding, asset-lock creation) that build and broadcast their funding transaction internally and expose no id to watch. Those paths are unchanged by this PR beyond the F-1 fix below.PendingConfirmationreconciler (src/app/reconcilers.rs, alongside the existingConnectionBanner/MigrationReconciler/SpvBlockReconcilerpattern) adopts the banner and polls the wallet's own already-event-sourced display snapshot (SnapshotStore::transaction_confirmation_any) every 2s for that txid to reach an InstantSend lock or a mined block with a known height.network_took_transactioninsrc/app.rs) guards against that explicitly, with a unit test (a_mined_tier_without_a_height_keeps_waiting).create_asset_lock_proof(src/wallet_backend/payments.rs) was still routing every broadcast failure through the genericWalletBackendenvelope, soCreateAssetLock/CreateTopUpAssetLockkept giving the "please retry" advice fix(wallet): stop advising a retry when a broadcast outcome is unknown #961 was written to eliminate. Now routed through the same classifier.Full architecture plan (source-verified against this repo and its
dash-spv/platform-walletgit deps): see the design doc Nagatha (architect) produced before implementation — happy to attach/paste on request; kept out of the repo since it's a working doc, not durable project documentation.Out of scope, with reasons (see
docs/user-stories.mdSND-018 and the architecture plan for the full rationale):Confirmedtier in DET's snapshot without a real network verdict, which would let the new banner falsely confirm a payment that never landed. Code-side mitigation is in place and unit-tested, but wants a live confirmation. A scenario is written up atdocs/gui-testing/scenarios/pending-broadcast-auto-reconcile.md(also closes R-4: does the watch resolve for a purely-outgoing send with no change output?) — run it before marking ready for review.Testing
cargo test --all-features(narrow scope:pending_,map_core_broadcast_error,transaction_confirmation, plus the extended fix(wallet): stop advising a retry when a broadcast outcome is unknown #961 test) — all passing, including 5 new kittest reconciler cases and the phantom-height guard test.cargo clippy --all-features --bin dash-evo-tool -- -D warnings— clean.cargo fmt --all— clean.🤖 Co-authored by Claudius the Magnificent AI Agent
