Final validation — Phase 1 + Phase 2
The new GUI provides substantial registration and maintenance functionality, but two imported-message signing paths can authorize unintended transfers. Saved-session navigation, operator-key preservation, and activation-state refresh also have reproducible defects in the source. Nine findings remain after verification; this verification used source and history inspection, without executing tests.

- [BLOCKING] src/qt/sharedmndialogs.cpp:1455-1458: Validate imported dissolution payouts before approving them
An imported Dissolve Together request reaches shared_sign without validating or displaying its actual payouts. SharedSigCollector checks the transaction type, masternode hash and signatures, but the actor and fee controls retain locally initialized values. For two 500-DASH shares, a malicious owner can name the victim as actor, omit the actor output and pay 999.999 DASH to the attacker's refund script. CheckProDisTxForList permits this once every owner signs: unanimous dissolutions allow bonuses beyond the configured penalty. Clicking Approve and Copy Reply therefore authorizes loss of the victim's principal despite the advertised free dissolution. Before signing, decode the transaction and either enforce the principal-returning template or require explicit approval of its actual actor, per-share payouts and fee.
In `src/qt/sharedmncreatedialog.cpp`:
- [BLOCKING] src/qt/sharedmncreatedialog.cpp:2400-2405: Restrict funding signatures to locally authorized coins
signrawtransactionwithwallet signs every input this wallet can sign, not only the participant's reserved contribution. adoptLockedTerms preserves previously recorded contributions but permits additional ones, while payloadMatchesEnvelope only checks consistency with the imported envelope. A malicious coordinator can preserve the victim's contribution, add another publicly known victim UTXO through an additional contribution, and direct its matching change to the attacker. Updating both the envelope and transaction passes those checks without increasing the aggregate fee, and this call signs the unauthorized input. Imported coin locks do not restrict raw signing. Verify wallet-signable inputs and their debit/change against locally authorized contributions before signing. Extend the regression coverage to mutate both the envelope and transaction; the existing extra-input test changes only the transaction.
- [BLOCKING] src/qt/sharedmncreatedialog.cpp:2761: Resume fully signed coordinator sessions on the broadcast page
Reopening a saved FundingSigned session identifies the coordinator correctly, but this branch sends it to PageWaitBroadcast. That page is absent from the coordinator's m_order, so goToPage returns without navigating and a fresh dialog remains on the landing page. Re-pasting the same file does not advance it either: absorbSession only refreshes a FundingSigned coordinator already on PageSignatures. This prevents the saved-session workflow from reaching Broadcast Registration. Route coordinators to PageSignatures and retain PageWaitBroadcast for participants.
- [BLOCKING] src/qt/sharedmncreatedialog.cpp:2626-2628: Prevent saving and closing from bypassing operator-key backup
Save and Save and Close remain available before the generated operator secret has been backed up, but the saved session contains only its public key. Reserve the coordinator's coins, reach PageSecret, and choose Save and Close without confirming the secret: closing destroys OperatorKeyWidget and clears the secret. Reopening the draft recognizes the coordinator, sets m_operator_key_from_import, skips PageSecret and opens PageInvite, allowing registration with an operator key nobody possesses. The imported-key UI also hides the key replacement widget. Require backup confirmation before allowing this session to be treated as safely saved and closed, or provide an explicit recovery-safe lifecycle. Keep the secret out of participant exchange envelopes.
- [SUGGESTION] src/qt/sharedmncreatedialog.cpp:2647-2653: Enforce the file size cap before reading the session file
onOpenFile reads the entire selected file and converts it to QString before handleImportedText enforces MAX_ENVELOPE_FILE_BYTES. An oversized file is therefore read, decoded and converted back to UTF-8 on the GUI thread before rejection, potentially freezing the application or exhausting memory. Check the file size before readAll, as SharedSigCollector::loadEnvelope already does, or use a bounded read that rejects content exceeding the cap.
In `src/qt/masternodelist.cpp`:
- [BLOCKING] src/qt/masternodelist.cpp:246-248: Refresh the activation gate when the chain tip changes
updateRegistrationAvailability is called only from setClientModel and setWalletModel. If the wallet opens before v24 activates, including during initial synchronization below activation, the Shared Masternode button remains disabled after the node reaches an active tip. Masternode-feed updates refresh the list but never this gate, so the new registration/session entry point stays unavailable until model setup is repeated, such as by reopening the wallet. Connect availability refresh to an appropriate chain-tip notification so the button follows activation changes.
- [SUGGESTION] src/qt/masternodelist.cpp:293-299: Identify the affected masternode before broadcasting a standby dissolution
The confirmation shows only the transaction ID and generic wording about ending a masternode. SharedMnImport::Detect recognizes the dissolution transaction type, but broadcastStandbyDissolution never decodes CProDisTx to identify which masternode will be dissolved. Selecting or pasting the wrong saved standby transaction therefore gives the user no meaningful way to detect the mistake before an irreversible broadcast. Decode the payload and display the target proTxHash, supplemented by available list details, and show the actor and actual payouts rather than assuming that every standby variant returns full principal.
In `src/Makefile.qt.include`:
- [SUGGESTION] src/Makefile.qt.include:343-347: Move build entries and prerequisites into their introducing commits
The engine, widgets, wizard and maintenance commits introduce their implementations without registering them in the Qt build; all source/header/MOC entries arrive in 6be098ea882. The maintenance implementation also uses MasternodeEntry's shared-share accessors and MasternodeStandby::SavedDate, which are introduced only in that later commit. Earlier dash-qt builds therefore exclude the new implementations rather than validate them, despite the stated self-contained commit structure. Move each layer's build entries into its introducing commit and introduce the required model/standby APIs no later than their first consumer.

Fixed in 7915bfc (folded into the maintenance-dialogs commit).
The collector now reads every dissolution it is asked to adopt against the masternode's share table (SharedMnReadDissolution in sharedmnwidgets.cpp) and only accepts the penalty-free template protx shared_dissolve_prepare builds: one input, one output per non-actor share in share order paying exactly its principal to its own refund script, and an optional final actor output paying principal minus fee, with 0 < fee <= CProDisTx::MAX_FEE. Anything else is refused in setTransaction() with a message telling the user not to approve and to ask for a fresh request, so it never reaches "Approve and Copy Reply". I chose enforcing the template over asking for explicit approval of arbitrary payouts: no GUI or RPC flow builds a unanimous dissolution of any other shape, and a numbers-on-screen confirmation is exactly what gets clicked through. On top of that the Together tab shows the adopted request's actual payouts and the fee next to the approve button.
Test: MasternodeMaintenanceTests::dissolveRequestMustReturnPrincipal covers the attack (victim named as actor, actor output omitted, collateral swept to another share's refund script), a stranger output, a fee past the ceiling, and the honest template with its payout table. The walkthrough test still adopts the node-built request end to end.

Resolved (re-reviewed at 8579e19e): Thank you; the collector now requires SharedMnReadDissolution to accept the principal-returning template before adopting a dissolution for signing. It checks non-actor amounts and refund scripts, the actor output and the fee bound, while the Together view displays the adopted payouts.

Fixed in fcd6f2e (folded into the wizard commit).
signOwnFundingInputs() now refuses before the wallet is even unlocked when the prepared transaction spends a coin this wallet can sign (txinIsMine & ISMINE_SPENDABLE) that is not among the inputs of our own contribution, and it re-checks the RPC result afterwards: a scriptSig that appeared on any input outside our contribution, a rewritten prevout or a changed input count is rejected and nothing is applied to the session. The same check runs when a session is imported or absorbed, so the Approvals and Signatures pages already show the refusal and keep their action disabled.
Tests: SharedMnWizardTests::refusesToSignCoinsOutsideOwnContribution builds the case you describe, with both the envelope and the transaction carrying the extra contribution that spends the victim wallet's publicly known coin with change to the attacker, so adoptLockedTerms and payloadMatchesEnvelope both pass, and asserts the dialog refuses with the outpoint named and the session untouched. unauthorisedSignedInputsAreDetected covers the post-check on hand-built transactions.

Resolved (re-reviewed at 8579e19e): Thank you; signOwnFundingInputs now rejects wallet-spendable inputs outside the local contribution before unlocking, then checks the signed result before applying it. The added regression constructs the consistent envelope-and-transaction attack rather than changing only the transaction.

Fixed in fcd6f2e. While a generated operator secret has not been confirmed, the Save button is disabled with a tooltip saying why, saveSession() refuses and returns to the key page, and closing the dialog shows a different prompt ("Save Operator Key" / "Discard and Release Coins" / "Cancel") that explains the key exists nowhere but this window. The session file still carries only the public key. SharedMnWizardTests::savingWaitsForTheOperatorKeyBackup checks the disabled button, that saving opens no file dialog and stays on the key page, and that confirming the last four characters releases it.

Fixed in 959e00a. setClientModel() now connects numBlocksChanged and masternodeListChanged to updateRegistrationAvailability() (and disconnects the previous model first), so the button follows activation. MasternodeWidgetTests::masternodeListRegistrationAvailability emits both signals and checks the state is re-derived, and that a detached model no longer reaches the list.

Done. The series is rebuilt so every commit registers its own files: the engine commit adds the engine/sender/RPC-name entries, the widgets commit its own, and so on; a new commit feat(qt): expose share details and standby records on the masternode model lands the MasternodeEntry share accessors and MasternodeStandby::SavedDate before the maintenance dialogs that use them. Each of the eight commits builds dash-qt and test_dash-qt on its own with -Werror.

Done in 959e00a. The confirmation now decodes the payload and lists the masternode (proTxHash plus service and collateral address from the list, or a note that it is not in the current list), which share pays the fee, whether every owner approved or only this wallet, every output as "Share k of n → amount" matched by refund script (or the address when unmatched), the fee, and it only claims that every share's principal is returned when the outputs actually say so.

Resolved (re-reviewed at 8579e19e): Thank you; broadcastStandbyDissolution now uses the decoded description before confirmation, including the masternode, available service details, approvals, actual outputs and fee. The principal-return statement is conditional on the payout-template check rather than assumed.

Compute m_operator_key_from_import before rebuildOrder().
rebuildOrder() reads secretGateRequired(), which reads m_operator_key_from_import. That flag is only recomputed later, inside refreshAll() → pushSessionToWidgets() (Line 2169). At Line 2861 the flag still holds the previous session's value, so rebuildOrder() decides the page order from stale state.
Trigger: a coordinator reopens a saved draft that carries an agreed operator key. m_operator_key_from_import is still false, and m_operator_widget->hasGeneratedSecret() is true because the widget generates a key on construction. secretGateRequired() therefore returns true and PageSecret is inserted into m_order.
Consequence: the resumed session keeps a spurious "Save operator key" page. The stage is Draft, so Back stays enabled on PageInvite (Line 1426). Pressing Back enters PageSecret, which fills m_secret_edit from m_operator_widget->secretHex() (Line 1256) — a freshly generated secret that is not the session's operator key. The dialog then asks the coordinator to back up and confirm the wrong key. Nothing recomputes m_order afterwards: refreshAll() does not call rebuildOrder(), and the key widget is hidden once the import flag is set, so its changed signal never fires.
Set the flag from the imported session before building the order.

Restore the measured widgets to hidden after sizing.
This loop forces five widgets visible so SharedMnSizeFromContent measures the tall layout. validateForm() then restores m_pose_warning, m_finish_banner and m_reason_label, but nothing restores m_result_edit or m_status_label. ShowStatusLabel is the only call that hides m_status_label, and it runs only after an action. The dialog therefore opens with an empty read-only field showing the "Transaction ID" placeholder, which suggests a rotation was already sent.
Hide both widgets again immediately after the measurement.

Re-review — Preliminary review — Phase 1 blocker gate
Verified the findings against head 8579e19 using source and commit-history inspection. All nine prior findings are addressed, but the saved-draft resume path still exposes an unrelated generated operator secret, and the rotation dialog leaves its empty result widgets visible after sizing. This is preliminary verification of the supplied reviewer evidence; tests were not run.
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.

- [BLOCKING] src/qt/sharedmncreatedialog.cpp:2861-2862: Set the imported operator-key flag before rebuilding the wizard order
When a coordinator reopens a saved Draft containing an operator public key, rebuildOrder() runs before refreshAll()->pushSessionToWidgets() sets m_operator_key_from_import. The initially false flag and the key generated by OperatorKeyWidget's constructor cause PageSecret to remain in the coordinator's page order. Back from PageInvite then displays and asks the user to save that newly generated secret, which does not correspond to the imported session's operator public key. The later refresh hides the key-selection widget but does not rebuild the page order. Initialize the imported-key flag before rebuilding the order so resuming a draft cannot prompt the user to back up the wrong operator key.

MnShareSession is the pure-logic engine behind the Qt shared masternode flows: a JSON envelope that participants exchange out of band, carrying the share table, terms, funding contributions, the prepared registration and the collected consent signatures. Imports are transactional, every signature is verified natively against the recomputed consent digest, and payloadMatchesEnvelope() refuses any envelope whose displayed terms, share table, funding inputs/outputs, collateral index or service addresses differ from the transaction that would actually be registered. Replies merge in any order (absorbDraftReply), a participant only adopts locked terms that contain exactly what they answered (adoptLockedTerms), and every envelope carries a human-checkable code (fingerprint) so two people can confirm over chat that they hold the same message. ProTxSender runs interfaces::Node::executeRpc off the GUI thread and translates RPC errors; sharedmnrpc.h holds the seven shared_* method names in one place so a typo cannot dead-end a multi-party flow. interfaces::Node gains isV24Active() and MnEntry exposes the share table.
…routing widgets SharedMnStatusBoard shows one row per participant with Details / Funded / Approved / Signed columns so the whole group's state is visible at a glance; names from envelopes are rendered as plain text only. SharedMnTermSheetHtml renders the escaped term sheet users approve. SharedMnImport::Detect tells a session envelope, a maintenance (dissolve/rotate) request and a standby dissolution hex apart so a single Paste button can route any message. Amount formatting and plurals go through one helper so every dialog agrees. Secondary buttons use a [mnSecondary] property selector in the existing theme CSS so each page has one filled primary action.
…model The maintenance dialogs need to know a shared masternode's share table, exit terms and whether a standby dissolution was already written for it, and the list needs to say which shares this wallet holds. MasternodeEntry now carries the shares, early period and penalty, and a per-share "mine" lookup; MasternodeStandby records the date a standby file was saved. The BLS key formatter moves into the header so the model, which is built without wallet support too, can group operator keys the same way.
A RegisterMasternodeWizard-style flow for registering a masternode funded by several people, built on MnShareSession. The coordinator fills in the participants, masternode settings, exit terms and their own contribution, saves the generated operator secret behind a confirmation gate, and copies one Invitation. Every participant pastes it, reserves coins for their share and copies back their Details. The remaining two rounds are the protocol minimum: Locked Terms out, Approvals back (consent signatures over the prepared registration), then a Signing Request out and Signed Contributions back (funding-input signatures after shared_combine). Replies merge in any order; the coordinator's own approval, the combine step and their own funding signature run automatically; the last page lists what to keep safe. Any message can be pasted on the landing page or with the Paste button and is routed by content. Every copy and paste shows the session code and a message code so participants can confirm over chat that they hold the same message. Pasted text is size-capped and the tamper warning of an edited envelope stays visible. Reopening a saved session restores the coordinator role from the envelope. Reserved coins are released after broadcast or when the session is discarded.
Change Reward Address updates one share's reward destination (with "Use refund address" to revert) and unlocks the wallet before calling shared_update_share. Rotate Operator or Voting Key and Dissolve Together share a request / approvals / send structure: whoever starts prepares the request and approves automatically, everyone else pastes it and copies back an approval, and the preparing wallet, identified by the transaction's fee inputs rather than by dialog state, sends the result. Dissolve Now shows the early-exit cost, the payout per share and needs an explicit acceptance. Standby Dissolution writes both variants (full principal after the early period, immediate with the penalty) into one file and records the date so the masternode list can show whether one exists. Shares are always "Share k of n", fees are amount fields, and dialogs size themselves from their content.
The Type cell reads "Shared (you hold k of n)", the owned filter counts a wallet's refund destination as ownership, the details view lists every share with 1-based numbers, percentages and the standby status, and the context menu offers Change Reward Address, Rotate Keys, Dissolve and Create Standby Dissolution for shared entries (Update Registrar is hidden for them). The "Shared Masternode…" button opens the wizard, and a pasted maintenance request or standby dissolution is routed to the right dialog.
MnShareSessionTests: share-table validation, envelope round trip and fingerprint, draft replies merging in any order, locked-terms adoption and its refusals (changed refund, coins, terms), funding-transaction and collateral-index verification, penalty preview math, early-period wording, signature verification, parallel funding-signature merge, and a check that every RPC name the GUI dispatches is registered. SharedMnWidgetTests: message detection, status board cells and escaping of untrusted names. SharedMnWizardTests: page order per role, role inference on paste, coordinator resume, participant gating, board updates in any order, paste routing, fingerprinted clipboard envelopes and unlock discarding approvals. MasternodeMaintenanceTests: reward-address rules, wallet unlock before sending, dissolve tabs and payouts, standby file format, operator-key validation, sender derived from transaction inputs and envelope preload. MasternodeWidgetTests: owned filter, context menu and details for shared entries. SharedMnWalkthroughTests drives the whole registration end to end against an in-process regtest node with three descriptor wallets, broadcasts the shared ProRegTx, mines it, verifies it in the deterministic masternode list and then exercises every maintenance dialog against the real entry. With DASH_QT_SHOTS_DIR set it also grabs each page as a PNG, which is how the screenshots in the pull request were produced. The Qt test fixture now installs the real URL decoder so "/wallet/<name>" RPC routing works with more than one loaded wallet.

Use the same ownership rule for share labels and counts.
A wallet that owns only share.scriptRefund passes the Owned filter here. However, my_share_counts and my_share_indexes check only share.keyIDOwner. The row then reports no wallet-held share, and the details dialog does not mark the share as “you.”

A simplification pass over this PR found that the new shared-masternode GUI had grown a third copy of the masternode dialog shell rather than promoting the second into MasternodeWidgetUtil, which exists for exactly that, and that four test files had each grown a private copy of the same fixture kit. It also turned up three defects worth fixing on their own.
Defects: the dissolution preview re-spelled the body of ProRataFloor() (evo/providertx_util.cpp) inline, so the GUI carried its own copy of DIP-0026 rounding and could silently drift from consensus; refreshBoards() recomputed every cell once per status board and fundingSignatureCount() decoded the registration per share, costing 48 DecodeHexTx calls per refresh where 2 suffice; and the details pane hardcoded BitcoinUnits::Unit::DASH while the rest of the flow honours the user's display unit, so one share showed two different units.
The details pane formats with BitcoinUnits::formatWithUnit() rather than the flow's SharedMnFormatAmount(): masternodemodel.cpp is in BITCOIN_QT_BASE_CPP and is linked into --disable-wallet GUI builds, where the shared-masternode TUs are absent.
Dead code: getShareOwnerKeyIds()/getShareRefundScripts() are element-wise projections of getShares() with the same source and order, leaving isOwnedBy() as their only caller; the UpdateShareDialog constructor re-ran the three gates validate() runs on the next line; and the share-owner loop feeding m_owner_address is unreachable now that every reader is guarded by !isShared().
Shared helpers: PAGE_TITLE_SIZE, makePageTitle, makeBlockTitle, makePageLayout, makeBlock, makeScroll, makeScrollBody and freshAddress move into MasternodeWidgetUtil, deleting verbatim copies from masternodewizard.cpp and sharedmncreatedialog.cpp. MakeHint was a pass-through to the existing makeHint and is gone. makeScrollBody returns its layout, removing nine unchecked qobject_casts, and absorbs the wizard's four open-coded scroll areas.
Tests: new qt/test/masternodetestutil.{h,cpp} holds WalletGuard, MakeDescriptorWallet, GuiModels, MakeInvitation, DraftReply, PrepareRegistration and the small key/address/txid helpers. Three wallet factories collapse into one; broadcasting stays opt-in because only one of the three enabled it. GuiModels also fixes five sites that asserted on OptionsModel::Init without reporting why it failed. These live in a Dash-specific file rather than qt/test/util.h, which is upstream.
Deliberately not done: UnlockHolder stays duplicated because masternodewidgets.h compiles in --disable-wallet builds and a WalletModel::UnlockContext member would need walletmodel.h there. The operator-secret page stays duplicated because the two versions differ in eight user-visible ways and unifying them needs three text parameters, two feature flags and a styling hook. sharedmnwidgettests.cpp stays separate because widget rendering is a distinct subject from the session engine. SharedMnCreateDialog keeps its fixed initial size because, unlike the single-page sibling dialogs, it stacks 13 pages and SharedMnSizeFromContent() would size every page to the tallest one.
No behaviour change beyond the three defects above. Qt suite: 145 passed, 0 failed.

that's a bit strange to have mixed htm code and logic
WalletImpl::getCoins() looked a requested outpoint up by txid and then read vout[n] without checking n against the transaction. Every caller so far passed outpoints the wallet itself had produced, but the shared masternode session file lists funding inputs written by other participants, and the GUI resolves those through getCoins() on import. A txid this wallet holds with an index past the end is now simply not a coin of this wallet, as an unknown txid already was. The import case in SharedMnWizardTests::refusesToSignShortChangedOwnContribution covers it. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…es this wallet The foreign-input check only caught a coin of ours listed under somebody else's contribution. A session file that lists our coins under our own label but sends the change to another address, or shrinks it, passed every envelope check (the file and the transaction agree with each other) and the wallet would sign it. A participant past the Draft stage is exposed whenever a higher-revision copy arrives, because that path replaces the session wholesale without re-running the adoptLockedTerms cross-checks, and a fresh import of a locked file has nothing local to compare against at all. checkOwnFunding() now also compares what this wallet puts into its own contribution against what comes back to it: the wallet's own view of its spendable inputs must not exceed its share plus change to an address it can spend from (plus the fee allowance for the coordinator). The refusal is stored as the message itself, which removes the outpoint-to-message indirection the pages went through. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
… masternode type fromJson() accepted any int64 for a share amount, a change amount and the early-exit penalty. Share amounts were bounded later by validateShares(), but change amounts are summed straight away by fundingCheck() and the term sheet on every import, so a pasted file could make that sum overflow. All three now have to pass MoneyRange() to parse, like every other amount taken from the network. payloadMatchesEnvelope() also required nType to be Regular. The wizard only ever registers regular masternodes and everything else that reads the payload assumes the regular collateral, so a payload claiming another type must not verify against the displayed session.

UpdateShareDialog took the wallet unlock through ensureUnlocked() but, unlike the typed submissions in its base class, never released it when the RPC failed: the wallet stayed unlocked for as long as the dialog stayed open. The failure path now goes through abortOperation(), which is what the base class does. MasternodeList asked the node isV24Active() on every numBlocksChanged and masternodeListChanged signal. That call takes cs_main on the GUI thread, so the list contended with validation on every block. Activation is monotonic, so once the answer is true it is cached for the rest of the session and the node is no longer asked. RotateSharedKeysDialog measured its window with the Transaction ID field and the status label shown, but only validateForm() ran afterwards and it re-hides neither, so an empty read-only Transaction ID field was on screen before any request existed. The Participants page did not treat clicking a Me radio as an edit, so after Next refused with 'Select the participant that is you' the error stayed until some other cell changed.

Three callers (the registration wizard, the maintenance dialogs and the standby broadcast in the list) each spun their own QEventLoop around ProTxSender::execute() to wait for the worker thread. executeAndWait() owns that loop now, and isBusy(), which nothing called, is gone. The wizard's runRpc() also takes the busy text and returns the failure sentence itself, so its five call sites lose the setBusy/ran/ok scaffolding they each repeated.

…n updates
The wizard rebuilt the session's JSON to drop unverified signatures and to swap in a freshly signed transaction, and both it and the engine spelled out the {shareIndex, signature} array separately. MnShareSession now offers signaturesJson(), dropUnverifiedSignatures() and replaceProTx(), so the dialog stops depending on envelope key names.
Inside the engine, decodeFrozen() replaces six copies of decode-then-compare-consent-hash that carried four wordings of the same refusal, SameShare() replaces two field-by-field comparisons, and a lambda replaces six identical malformed-contribution blocks in fromJson(). FingerprintOf(), missingIndexes(), verifyAllSignatures() and signatures() had no callers left and are gone; SessionCode() is folded into sessionCode().
No behaviour change.

SharedMnWalletOwnsShare() replaces eight spellings of 'this wallet can sign with that share's owner key' across the maintenance dialogs and the list, three of which had forgotten the private-keys-disabled guard the others carried. SharedMnV24InactiveMessage() replaces a helper private to one file plus two re-typed copies of its sentence in the wizard. The wizard handed maintenance messages up to the list by walking its QObject ancestors for an openSharedMessage(QString) slot found by name. It now emits maintenanceMessage() and the list, the only thing that ever constructs it, connects to that; the Q_INVOKABLE and the runtime lookup are gone. Also drops an unneeded const_cast, a copy of a label, six unused includes, a redundant forward declaration and a stale comment. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
Fourteen assertions pinned button captions, window titles, tab labels or the exact <td> markup of the details pane. The page transitions and enabled states around them already prove the behaviour, so each of those was a future false failure on a copy edit. They are gone; the tooltip and details checks keep the one substring that is the invariant. masternodetestutil was meant to hold the shared fixture but three copies survived: masternodewidgettests had its own TestKeyID next to the include, sharedmnwidgettests its own FreshP2PKHAddress, and the rotation-sender test hand-rolled the keyless descriptor wallet MakeTestWallet builds. Those use the util now, and the using-declarations the move left behind are removed. Also drops two redundant textChanged emits, a tautological visibility check, an orphaned comment and three exact-wording checks of the early-period text whose rounding cases and (s)-free loop already cover it.

… typed interfaces::EVO requests dcfa6bc refactor(qt): remove ProTxSender and the shared masternode RPC name table (pasta) adbd88a refactor(qt): drive the shared masternode dialogs through MasternodeOperationRunner (pasta) cb71f0a refactor(qt): run shared masternode operations on MasternodeOperationRunner (pasta) a5316ef refactor(interfaces): expose the shared masternode operations on interfaces::EVO (pasta) 1635ca0 refactor(evo): build shared masternode transactions in the provider service (pasta) Pull request description: ## Issue being fixed or feature implemented Follow-up to #7701, rebased onto develop after it merged. The shared masternode GUI from #7701 reaches the seven `protx shared_*` RPCs by name: `ProTxSender` turns every action into an `interfaces::Node::executeRpc` call against `/wallet/<name>`, waits for it in a nested `QEventLoop`, and parses the JSON reply back apart. The RPCs themselves build, fund, sign and submit their transactions inline and finish them by re-entering `signrawtransactionwithwallet` and `sendrawtransaction` through the RPC table. The rest of the masternode GUI already works differently: typed requests in `interfaces/providertx.h`, `interfaces::EVO` methods forwarding to `evo::provider` service functions, and `MasternodeOperationRunner` running them off the GUI thread. This gives the shared operations that same shape and removes the RPC-by-name bridge. ## What was done? 1. **Service functions** (`src/evo/providertx_service.{h,cpp}`, `src/interfaces/providertx.h`): `PrepareSharedRegistration`, `SignShared`, `CombineShared`, `DissolveShared`, `PrepareSharedDissolution`, `UpdateShare` and `PrepareSharedRegistrarUpdate`, with typed request and result structs, return a `ProviderTxError` instead of throwing. The transaction building moved over from `src/rpc/evo.cpp` mostly verbatim. Signing goes through `interfaces::Wallet::signSpecialTxPayload`/`signTransaction`, submission through the same `BroadcastTransaction` call and fee cap `sendrawtransaction` uses. `Finish()` gains an `allow_partial` flag so the shared path can keep returning a transaction that is only partly signed when `submit=false`, as it always has. 2. **RPC handlers** now parse their parameters, call the service through `UnwrapOrThrow`, and render the same JSON. Every error keeps its RPC code and message: each old `JSONRPCError` maps to the `ProviderTxErrorCode` that `ThrowProviderTxError` turns back into the same code. 3. **`interfaces::EVO`** gets seven methods forwarding to the service, exactly like `registerMasternode` and friends. 4. **`MasternodeOperationRunner`** gets the seven typed operations on its existing `run<>` template, plus one `errorText()` that replaces the two copies of `ProviderTxErrorText` (wizard and maintenance dialogs) and absorbs `ProTxSender`'s table of reject reasons with a user-facing explanation, so every masternode flow shares it. 5. **GUI**: `SharedMnCreateDialog`, `DissolveDialog`, `RotateSharedKeysDialog` and `UpdateShareDialog` build typed requests and run them on the runner, holding the wallet unlock and the busy state until the callback, the way `RegisterMasternodeWizard::startSubmit` does. That removes the last nested `QEventLoop`. `UpdateShareDialog` submits through `MasternodeActionDialog::startSubmission` like its siblings, so `ensureUnlocked()` and `setBusy()` go back to private as they are on develop. Funding-input signing calls `interfaces::Wallet::signTransaction`, broadcasting calls `interfaces::Node::broadcastTransaction`. `checkOwnFunding()`, `signedOnlyOwnInputs()`, `ownContributionError()` and the dissolution template and digest cross-checks run exactly as before. 6. `qt/protxsender.{h,cpp}` and `qt/sharedmnrpc.h` are deleted, along with `MnShareSessionTests::rpcMethodNamesAreRegistered`, which only guarded the RPC name table. Deliberate differences, all limited to inputs that are invalid in more than one way: - The RPC layer still does all parameter parsing that quotes the caller's input (addresses, keys, index ranges, signature entries) and does it before calling the service. When a parameter is malformed and a chain-dependent check (such as "shared masternode not found") would also fail, the parameter error now wins. - `shared_combine` on a ProUpSharedRegTx resolves and unlock-checks the wallet before the payload checks. Before, that happened inside `signrawtransactionwithwallet` after them. - For `shared_register_prepare`, an empty string inside a `coreP2PAddrs` array now fails with the same "cannot be empty" message the other registration RPCs already give, not the netinfo error. - `UpdateShareDialog` now shows the same "transaction was sent" confirmation as the other maintenance dialogs before it closes. - The reject-reason explanations now also apply to the regular registration wizard and maintenance dialogs. The two about unactivated transaction versions no longer name v24, since they can now appear outside the shared flows. - The GUI broadcasts the finished registration and standby dissolutions through `interfaces::Node::broadcastTransaction`, the way the PSBT dialog does. Unlike `sendrawtransaction`, it does not wait for the wallet to process the new transaction before returning. Funding-input signing and broadcasting are quick and now run directly on the GUI thread, like sending coins. ## How Has This Been Tested? macOS arm64, depends build, `--enable-debug --enable-werror --with-gui=qt5`: - `test/functional/test_runner.py feature_masternode_shares.py feature_masternode_payout_shares.py`: pass, test files unchanged. - `QT_QPA_PLATFORM=minimal src/qt/test/test_dash-qt`: all 145 cases pass (146 before, minus the removed name-table test). `SharedMnWalkthroughTests` still drives three real wallets end to end through the typed path: lock, approve, combine, sign, broadcast, confirm on chain, then the dissolve, standby and rotate dialogs against the registered masternode. - `src/test/test_dash`: pass. - `lint-whitespace`, `lint-includes`, `lint-circular-dependencies`, `lint-assertions`, `lint-include-guards`, `lint-format-strings`, `lint-qt-translation`: pass. - Every commit builds on its own with `-Werror`. ## Breaking Changes None. RPC output and error codes are unchanged; see the note above on which error is reported when several parameters are invalid at once. ## Checklist: - [x] I have performed a self-review of my own code - [x] I have commented my code, particularly in hard-to-understand areas - [x] I have added or updated relevant unit/integration/functional/e2e tests - [ ] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ 🤖 Generated with [Claude Code](https://claude.com/claude-code) Top commit has no ACKs.

…tests 2543d64 fix(qt): resolve clang-tidy errors in shared masternode tests (pasta) Pull request description: ## Issue being fixed or feature implemented Since #7707, `.clang-tidy` has `WarningsAsErrors: '*'`, so every clang-tidy finding fails the lint step. #7701 (shared masternode Qt GUI) then merged Qt tests that trigger ten clang-tidy checks. As a result, develop's `linux64_multiprocess-build` job has failed in its "Run linters" step since e5de15a (e.g. https://github.com/dashpay/dash/actions/runs/35780433329/job/106931610784). ## What was done? This change only touches tests (`src/qt/test/`). It makes mechanical fixes for exactly the ten errors in the failing job log (deduplicated): - `masternodetestutil.cpp:114` `performance-no-automatic-move`: dropped `const` from the local `shared_ptr<CWallet>` so the return can move it. - `masternodetestutil.cpp:211`, `masternodemaintenancetests.cpp:613` `bugprone-argument-comment`: changed `/*bls_legacy_scheme=*/` to `/*specificLegacyScheme=*/` to match the parameter name of `CBLSLazyWrapper::Set`. The callee is unchanged. - `masternodewidgettests.cpp:212` `performance-inefficient-vector-operation`: added `ret.reserve(m_shares.size())` before the `push_back` loop. - `mnsharesessiontests.cpp:695,698,725` `performance-unnecessary-copy-initialization`: `alice`, `bob` and `conflicting` are now `const MnShareSession&` bound to the function-local `std::optional`s they were copied from. Each optional outlives its reference, and `mergeEnvelope` takes `const MnShareSession&`. - `masternodemaintenancetests.cpp:683,685,925` `performance-unnecessary-copy-initialization`: `shares` and `voting` are now `const&` to `MasternodeEntry::shares()` / `votingAddress()`. The `entry` they reference is a function-local that is only passed on by const reference (`UpdateShareDialog` / `DissolveDialog` constructors), so the references stay valid. ## How Has This Been Tested? On macOS arm64, with depends and `--enable-debug`: - `make -C src qt/test/test_dash-qt` builds cleanly. - `QT_QPA_PLATFORM=minimal src/qt/test/test_dash-qt`: every suite passes, including MasternodeWidgetTests, MnShareSessionTests, MasternodeMaintenanceTests, SharedMnWidgetTests, SharedMnWizardTests and SharedMnWalkthroughTests. The only skip is the existing `OptionTests::updateFontsWithPixelSizedWidget`, which cannot run under the minimal platform plugin. - I ran clang-tidy (Homebrew LLVM 22.1.8; CI uses llvm-19) with the repo `.clang-tidy` on the four files, using a compile database built from the real compile commands. On the base commit it reproduces all ten errors from the CI log. With this change it reports zero diagnostics. - `contrib/devtools/clang-format-diff.py` reports nothing for the diff. ## Breaking Changes None.

#7437 shipped the consensus, mempool and RPC side of Decentralized Masternode Shares, but the only way to register or maintain a shared masternode is seven
protx shared_*RPCs plus hand-carried hex and base64 blobs. This PR adds the Qt GUI so that a group of people who already know each other can register a shared masternode, exchange exactly the data the protocol needs, keep what has to be kept safe, and later change a reward address, rotate keys or dissolve, without touching the RPC console.Finding other participants is out of scope. Everything is exchanged as JSON messages the participants paste through whatever channel they already use.
What was done?
Registration wizard (
Masternodestab →Shared Masternode…), built on the same skeleton as the masternode registration wizard:shared_register_prepare+shared_sign); Signing Request out and Signed Contributions back (shared_combine+signrawtransactionwithwallet), thensendrawtransaction. Replies merge in any order; the coordinator's own approval, the combine step and their own funding signature run automatically.Paste From Clipboard/Open File…entry point routes any message by content. Every copy and paste shows a session code and a message code so two people can confirm over chat that they hold the same message.Engine (
MnShareSession): transactional JSON import, native verification of every consent signature, and apayloadMatchesEnvelope()check that refuses an envelope whose displayed share table, terms, funding inputs and outputs, collateral index or service addresses differ from the transaction that would actually be registered. A participant only adopts locked terms that contain exactly what they answered.Maintenance dialogs: Change Reward Address (with
Use refund addressto revert; unlocks the wallet first), Rotate Operator or Voting Key and Dissolve Together (request → approvals → send, sender identified by the transaction's fee inputs), Dissolve Now (early-exit cost, per-share payout table, explicit acceptance), Standby Dissolution (both variants written to one file, date recorded).Masternode list: Type cell reads
Shared (you hold k of n), the owned filter counts a wallet's refund destination, the details view lists every share, and the context menu offers the four shared actions (Update Registrar hidden for shared entries). Pasting a maintenance request or standby hex into the list opens the right dialog.Refusals the wallet makes on the user's behalf: a participant's wallet will not sign a funding transaction that spends a coin of theirs outside their own contribution, even when the envelope and transaction agree; a share owner will not be offered a "Dissolve Together" request unless it returns every share its full principal (the only shape the RPCs build), and the request's actual payouts are shown next to the approve button; a standby dissolution is described (masternode, actor, approvals, every output, fee) before it is broadcast; and the wizard cannot be saved or closed away from a generated operator secret that has not been confirmed.
The branch started from the pre-existing UI prototype (
origin/codex/mn-shares-ui-on-7437). That prototype dispatched five of the seven RPCs by names that do not exist and mis-parsed theshared_signresult, so no flow could complete; the history here is reorganised into eight self-contained commits rather than carrying those fix-ups, and every commit registers its own files in the build.Screenshots

How Has This Been Tested?
SharedMnWalkthroughTests(new, intest_dash-qt) drives the whole registration end to end against an in-process regtest node with three descriptor wallets: coordinator and two participants through all three rounds, broadcast, one confirmation, the entry verified in the deterministic masternode list, then every maintenance dialog opened on that real entry including a liveshared_dissolve_prepare/shared_signand standby generation. WithDASH_QT_SHOTS_DIRset it writes the screenshots linked above.MnShareSessionTests,SharedMnWidgetTests,SharedMnWizardTests(new) and extendedMasternodeMaintenanceTests/MasternodeWidgetTestscover the engine invariants (fingerprint, merge in any order, locked-terms adoption and refusals, funding-transaction verification, penalty math, signature verification), message routing, page gating and role inference, coordinator resume (draft and fully signed), the refusal to sign coins outside the wallet's own contribution with a consistent envelope and transaction, the operator-key backup gate, the dissolution template check and payout table, the activation gate following the chain tip, the standby broadcast description, wallet unlock before sending, sender derivation, envelope preload, and the list/menu/details behaviour. One test asserts every RPC name the GUI dispatches is registered.test_dash-qt: 14 suites, 139 cases, 0 failures (macOS, bothQT_QPA_PLATFORM=minimalandminimal:enable_fonts).test_dash: 983 cases, no errors.feature_masternode_shares.pyandfeature_masternode_payout_shares.pypass.test/lint/all-lint.pyandtest/lint/lint-cppcheck-dash.pypass.dash-qtandtest_dash-qton its own with-Werror, including-Werror=missing-field-initializersas CI does.Not covered: driving the real
dash-qtwindow with a mouse on this machine (screen locked during the session). The screenshots areQWidget::grab()of the real dialog classes under the headless platform, so message boxes render narrow there; that is a capture artefact.Breaking Changes
None. Everything is gated on v24 being active and on the wallet holding a share owner key. The test fixture change (
URL_DECODEinsrc/test/util/setup_common.cpp) makes/wallet/<name>RPC routing work in tests with more than one wallet loaded and does not affect any existing test.Checklist:
