Descriptor wallets upgraded from a release that stored the CoinJoin salt under ps_salt can legitimately contain DBKeys::PRIVATESEND_SALT: InitCJSaltFromDb() explicitly reads that key and migrates it to cj_salt. This new generic legacy-entry rejection runs during the database scan before that migration, so affected wallets are now rejected as tampered with and cannot be loaded. Exclude the migratable CoinJoin salt from this check or migrate it during loading.

With this default set to true, WalletImpl::fundTransaction() still selects the UTXOs matching fund_destination but never overrides m_allow_other_inputs. Provider-transaction funding reaches that method through src/evo/providertx_service.cpp; when the requested address is short of the target, coin selection can now silently add inputs belonging to unrelated wallet addresses instead of reporting insufficient funds for the specified source. Adapt this Dash-specific caller to disable other inputs.

There was a problem hiding this comment.
When preset inputs cover the target, this unconditionally adds every preset input and ignores coin_control.fRequireAllInputs. WalletImpl::fundTransaction() deliberately sets that flag to false after selecting every UTXO at the requested funding address, so provider transactions now consolidate all UTXOs at that address rather than the smallest sufficient subset, potentially creating an oversized transaction and unnecessarily increasing fees and privacy leakage. Preserve the former minimum-input path when this flag is false.

The hash passed to Dash's BlockManager::AddToBlockIndex() is always null. That method keys m_block_index by the supplied hash, so after the first iteration every subsequent call returns the same block-index entry; the tip remains at height 1, the generated coinbase repeats, and the benchmark's expected-balance assertion fails before any measurement runs. Pass block.GetHash() when adapting this benchmark to the Dash API.

Report descriptor setup failures through the test framework.
Assert(keystore.AddWalletDescriptor(...)) can terminate the entire test process when descriptor setup fails. This condition does not represent undefined behavior, memory corruption, or persisted/consensus-state corruption. Replace it with a non-aborting test failure path.
As per coding guidelines, assert(cond) / Assert(cond) is reserved for cases where continuing would be unsafe.

Successful callers immediately dereference the returned ScriptPubKeyMan. Assert establishes the required non-null precondition after AddWalletDescriptor; continuing with a null result would make the subsequent IsMine calls unsafe.
There was a problem hiding this comment.
@thepastaclaw, agreed that the non-null precondition is required before callers dereference the result.
The issue is the failure mechanism. BOOST_REQUIRE can enforce the same precondition and stop the current test case when AddWalletDescriptor fails. This prevents the unsafe IsMine dereference without terminating the complete test process.
For example, store the result, use BOOST_REQUIRE(spk_manager), then return spk_manager.

The proposed Assume sequence always evaluates *result.last_scanned_height. If an earlier scan invariant fails and that optional is empty, the change can introduce undefined behavior instead of safely reporting a test failure.

@thepastaclaw, the implementation confirms your concern.
Assume() is an identity function unless ABORT_ON_FAILED_ASSUME is set. A failed Assume() can therefore return false and execution continues. The next statement can dereference an empty result.last_scanned_height.
The previous withdrawal was incorrect. The proposed all-Assume replacement is unsafe. The check that establishes result.last_scanned_height before dereference must remain fatal, or the dereference must be guarded. I also verified that this repository rejects NDEBUG, so the current assert() sequence aborts on failure.

Preliminary review — Codex only
Verification confirms six blocking issues in the backport: CoinJoin selection loses its fully-mixed mode, selected-input balances are misreported, legacy CoinJoin salts prevent descriptor-wallet loading, the new benchmark aborts during setup, the AddInputs API is inconsistent, and the advertised bitcoin#25344 behavior is absent. The benchmark failure reproduces locally, while the coinselector and IsMine unit suites pass; two undeclared upstream test gaps, one ineffective unit-test setup, and one commit-message issue remain as suggestions.

These findings are from an automated code review. Verify each finding against the current code and only fix it if needed.
In `src/wallet/spend.cpp`:
- [BLOCKING] src/wallet/spend.cpp:526-538: Preserve the fully-mixed mode during coin selection
Both calls to ChooseSelectionResult omit nCoinType, so its CoinType::ALL_COINS default is used even when AutomaticCoinSelection requested CoinType::ONLY_FULLY_MIXED. ChooseSelectionResult derives the fully-mixed behavior passed to KnapsackSolver and SelectCoinsSRD from this argument. Losing it removes the denomination-aware selection restrictions, while CreateTransactionInternal still forces change to zero for fully mixed transactions. A CoinJoin spend can consequently select surplus value as a fee or fail the maximum-fee check despite an appropriate mixed selection being available. Pass nCoinType to both ChooseSelectionResult calls.
- [BLOCKING] src/wallet/spend.cpp:359-362: Include preselected inputs in the available balance
AvailableCoins now deliberately excludes every manually selected outpoint because transaction creation fetches those inputs separately, but GetAvailableBalance still returns only AvailableCoins(...).total_amount. The Qt prepareTransaction and useAvailableBalance paths pass the active coin control here. Selected inputs are therefore omitted, and when m_allow_other_inputs is false, unrelated unselected coins may be reported even though transaction creation cannot use them. This can reject a transaction funded by its selected inputs or fill “use available balance” with an unfundable amount. Account for validated selected inputs and include ordinary AvailableCoins only when other inputs are allowed.
In `src/wallet/walletdb.cpp`:
- [BLOCKING] src/wallet/walletdb.cpp:390: Allow the migratable legacy CoinJoin salt
DBKeys::LEGACY_TYPES includes DBKeys::PRIVATESEND_SALT (`ps_salt`), but older descriptor wallets can legitimately contain this key. CWallet::InitCJSaltFromDb explicitly reads `ps_salt` when `cj_salt` is absent and migrates it, but CWallet::LoadWallet invokes that migration only after WalletBatch::LoadWallet succeeds. This new rejection therefore returns UNEXPECTED_LEGACY_ENTRY before migration and makes those wallets unloadable. Exempt PRIVATESEND_SALT while continuing to reject legacy key and script records.
In `src/bench/wallet_create_tx.cpp`:
- [BLOCKING] src/bench/wallet_create_tx.cpp:66-67: Index each generated block by its actual hash
The benchmark passes a null uint256 to BlockManager::AddToBlockIndex. That function keys m_block_index by the supplied hash, so every iteration after the first returns the same height-one index instead of extending the chain. No generated coinbase becomes mature, and the balance assertion aborts before measurement starts. Running `./src/bench/bench_dash -filter=WalletCreateTxUseOnlyPresetInputs -sanity-check` reproduces the assertion failure at line 107.
In `src/rpc/rawtransaction_util.h`:
- [BLOCKING] src/rpc/rawtransaction_util.h:42: Match the AddInputs declaration to its implementation
The header declares AddInputs with a third bool argument, while rawtransaction_util.cpp defines and calls only the two-argument overload. The built rawtransaction_util object contains only `AddInputs(CMutableTransaction&, UniValue const&)`; a translation unit using the exposed declaration will fail to link, while the implemented overload is unavailable through the header. Make the declaration match the Dash-adapted implementation.
In `src/wallet/rpc/spend.cpp`:
- [BLOCKING] src/wallet/rpc/spend.cpp:937-938: Missing fee-bumper prerequisite chain for bitcoin#25344
Upstream merge 73966f75f67fb797163f0a766292a79d4b2c1b70 adds an `outputs` option to bumpfee_helper, parses it through AddOutputs, forwards replacement outputs through feebumper::CreateRateBumpTransaction, updates feebumper.{cpp,h} and wallet/interfaces.cpp, and adds wallet_bumpfee.py coverage. This backport changes only the generic raw-transaction helpers and documentation because Dash lacks the fee-bumper implementation and bumpfee/psbtbumpfee RPC chain. Commit 0c8c40533e3 and the PR title nevertheless advertise bitcoin#25344 as a full merge. Backport the applicable prerequisites and omitted behavior/tests, or explicitly mark and document bitcoin#25344 as partial.
In `src/test/fuzz/kitchen_sink.cpp`:
- [SUGGESTION] src/test/fuzz/kitchen_sink.cpp:46-48: Dropped fuzz-test transformations from bitcoin#22621
Upstream commit 32fa49a18497a9b8c72e36a72ae96e7b23930223 updates kitchen_sink.cpp to round-trip active OutputType values through FormatOutputType and the new optional-returning ParseOutputType API, fuzzes arbitrary strings, and adapts the corresponding string.cpp call. At this head, no test calls ParseOutputType and kitchen_sink.cpp only gains an unused `<optional>` include. Although fdef1a29cbf is labeled partial, its backport note identifies only m_default_address_type changes as missing and does not disclose these test omissions. Adapt the supported LEGACY/UNKNOWN fuzz coverage or document the exact exclusions.
In `src/wallet/test/ismine_tests.cpp`:
- [SUGGESTION] src/wallet/test/ismine_tests.cpp:240-242: bitcoin#25942 omits supported descriptor IsMine cases
Upstream merge e2bfd41f832dc7c7be6f17e928352f0eb2865f66 is test-only and includes descriptor coverage for rejecting nested `sh(sh(...))` and for `combo(...)` IsMine behavior. Dash omits those blocks along with genuinely unsupported Witness and Taproot cases, even though the current descriptor parser explicitly rejects nested sh() and its ComboDescriptor supports the legacy P2PK, P2PKH, and P2SH forms. The placeholder here is also mislabeled as an uncompressed-P2PKH case. Restore the supported nested-sh and legacy combo assertions and document only the Witness/Taproot exclusions.
In `src/wallet/test/coinselector_tests.cpp`:
- [SUGGESTION] src/wallet/test/coinselector_tests.cpp:325-332: Construct test outputs with the intended input size
CoinsResult::All() returns a vector by value, so both assignments to `available_coins.All().at(0).input_bytes` modify temporary copies. In addition, COutput calculates its fee and effective value during construction, so changing input_bytes afterward would not establish the intended negative-effective-value setup. Pass `custom_size=40` to add_coin when constructing both outputs and remove the ineffective assignments.

🔴 Blocking: Preserve the fully-mixed mode during coin selection
Both calls to ChooseSelectionResult omit nCoinType, so its CoinType::ALL_COINS default is used even when AutomaticCoinSelection requested CoinType::ONLY_FULLY_MIXED. ChooseSelectionResult derives the fully-mixed behavior passed to KnapsackSolver and SelectCoinsSRD from this argument. Losing it removes the denomination-aware selection restrictions, while CreateTransactionInternal still forces change to zero for fully mixed transactions. A CoinJoin spend can consequently select surplus value as a fee or fail the maximum-fee check despite an appropriate mixed selection being available. Pass nCoinType to both ChooseSelectionResult calls.

🔴 Blocking: Include preselected inputs in the available balance
AvailableCoins now deliberately excludes every manually selected outpoint because transaction creation fetches those inputs separately, but GetAvailableBalance still returns only AvailableCoins(...).total_amount. The Qt prepareTransaction and useAvailableBalance paths pass the active coin control here. Selected inputs are therefore omitted, and when m_allow_other_inputs is false, unrelated unselected coins may be reported even though transaction creation cannot use them. This can reject a transaction funded by its selected inputs or fill “use available balance” with an unfundable amount. Account for validated selected inputs and include ordinary AvailableCoins only when other inputs are allowed.

🔴 Blocking: Index each generated block by its actual hash
The benchmark passes a null uint256 to BlockManager::AddToBlockIndex. That function keys m_block_index by the supplied hash, so every iteration after the first returns the same height-one index instead of extending the chain. No generated coinbase becomes mature, and the balance assertion aborts before measurement starts. Running ./src/bench/bench_dash -filter=WalletCreateTxUseOnlyPresetInputs -sanity-check reproduces the assertion failure at line 107.

🔴 Blocking: Match the AddInputs declaration to its implementation
The header declares AddInputs with a third bool argument, while rawtransaction_util.cpp defines and calls only the two-argument overload. The built rawtransaction_util object contains only AddInputs(CMutableTransaction&, UniValue const&); a translation unit using the exposed declaration will fail to link, while the implemented overload is unavailable through the header.

🟡 Suggestion: bitcoin#25942 omits supported descriptor IsMine cases
Upstream merge e2bfd41 is test-only and includes descriptor coverage for rejecting nested sh(sh(...)) and for combo(...) IsMine behavior. Dash omits those blocks along with genuinely unsupported Witness and Taproot cases, even though the current descriptor parser explicitly rejects nested sh() and its ComboDescriptor supports the legacy P2PK, P2PKH, and P2SH forms. The placeholder here is also mislabeled as an uncompressed-P2PKH case. Restore the supported nested-sh and legacy combo assertions and document only the Witness/Taproot exclusions.

🟡 Suggestion: Construct test outputs with the intended input size
CoinsResult::All() returns a vector by value, so both assignments to available_coins.All().at(0).input_bytes modify temporary copies. In addition, COutput calculates its fee and effective value during construction, so changing input_bytes afterward would not establish the intended negative-effective-value setup. Pass custom_size=40 to add_coin when constructing both outputs and remove the ineffective assignments.

Tried, and reverted: with custom_size=40 actually taking effect the group
handed to SelectCoinsBnB has a negative selection amount and trips its
precondition assert(utxo.GetSelectionAmount() > 0) (coinselection.cpp:102).
In production, negative-effective-value coins are filtered out by
positive_only grouping before BnB ever runs, so BnB asserts on such input
rather than tolerating it. The test comment ("The next check should assert
if this somehow got through") documents exactly that tripwire, and upstream
master still carries these two statements verbatim - keeping them 1:1 is
intentional.
9f8eea2 docs: clarify backport assertion policy exceptions (PastaClaw) Pull request description: ## Issue being fixed or feature implemented Follow-up to #7615. Its condensed agent guidance correctly protects user-facing binaries, but reviewers can apply it too broadly to Bitcoin Core backports and test-only code. For example, the review comment in #7646 proposed replacing upstream `assert` calls in `src/wallet/test/util.cpp` solely to satisfy the production assertion policy, even though that source is linked into the unit-test binary rather than `dashd` or `dash-qt`. ## What was done? Updated the byte-identical `AGENTS.md` and `CLAUDE.md` guides to clarify two boundaries: - For Bitcoin Core backports, absent a clear bug, prefer remaining aligned with upstream rather than requesting Dash-only policy or style changes. Dash-specific correctness, security, and consensus issues remain valid reasons to adapt upstream code. - In C++ regression and unit-test sources under `src/test/` and `src/wallet/test/`, `assert`, `Assert`, `Assume`, and related fatal test checks are all acceptable. Their selection should not be flagged as a production-crash risk because these sources compile into test binaries, not user-facing applications. The exception is intentionally limited to the two requested test directories. The production-binary safety and untrusted-input guidance from #7615 remains unchanged. `doc/developer-notes.md` is also unchanged because this follow-up scopes agent/reviewer behavior rather than weakening the developer-facing production guidance. ## How Has This Been Tested? Documentation-only change. Validation performed: - `cmp -s AGENTS.md CLAUDE.md` - `test/lint/lint-whitespace.py` - `codespell --check-filenames --disable-colors --quiet-level=7 --ignore-words=test/lint/spelling.ignore-words.txt AGENTS.md CLAUDE.md` - `git diff --check upstream/develop..HEAD` - Exact-head pre-PR review gate: `ship` with zero findings ## Breaking Changes None. ## Checklist: - [x] I have performed a self-review of my own code - [ ] I have commented my code, particularly in hard-to-understand areas - [ ] I have added or updated relevant unit/integration/functional/e2e tests - [x] I have made corresponding changes to the documentation - [ ] I have assigned this pull request to a milestone _(for repository code-owners and collaborators only)_ Top commit has no ACKs.

The commit advertises bitcoin#25344, but a repository-wide search finds no bumpfee or psbtbumpfee RPC, and the only ported portion is this documentation refactor for send and walletcreatefundedpsbt; the upstream implementation and tests named in the imported commit message are absent without a partial-backport note. Consequently, none of bitcoin#25344's user-facing outputs behavior is delivered, so either include the prerequisite RPC hunks and tests or explicitly document and retitle this as a partial backport.

Ensure explicit collateral outpoints cover fees
When gobject prepare receives outputHash and outputIndex, GenBudgetSystemCollateralTx disables additional inputs. If the outpoint's effective value is below amount + not_input_fees, CreateTransaction returns Insufficient funds. Ensure callers select an outpoint with sufficient effective value, or allow additional inputs for the fee.

Boost.Test BOOST_CHECK non fatal BOOST_REQUIRE fatal assertion documentation
💡 Result:
In the Boost.Test framework, assertions are categorized by severity levels, which determine the behavior of the test execution upon failure [1]. The primary difference between BOOST_CHECK and BOOST_REQUIRE relates to whether the assertion is fatal [1]. BOOST_CHECK (Non-fatal) BOOST_CHECK is considered a non-fatal assertion [1]. If the predicate evaluates to false, the framework logs an error and increments the failure counter, but the test case execution continues normally [1]. This is the most common assertion level and is ideal for verifying conditions that do not prevent the remainder of the test case from executing meaningfully [1]. BOOST_REQUIRE (Fatal) BOOST_REQUIRE is considered a fatal assertion [1]. It acts as a strict requirement or precondition for the test [1]. If the predicate evaluates to false, the framework logs a fatal error, increments the failure counter, and immediately aborts the execution of the current test case [1][2]. This is appropriate when a failure makes subsequent testing steps impossible or unsafe [1][2]. Summary Table Level: WARN Behavior: Logs a warning, continues execution, test status unaffected [1]. Level: CHECK Behavior: Logs an error, continues execution, test marked as failed [1]. Level: REQUIRE Behavior: Logs a fatal error, aborts current test case, test marked as failed [1]. These levels apply to both classic macros (e.g., BOOST_CHECK, BOOST_REQUIRE) and the modern universal testing macro BOOST_TEST (e.g., BOOST_TEST, BOOST_TEST_REQUIRE) [3][4].

Use BOOST_REQUIRE for the parse invariant.
If success is true and Parse returns nullptr, BOOST_CHECK records the failure and continues. WalletDescriptor then dereferences the null descriptor in DescriptorID(*descriptor), causing undefined behavior. Replace BOOST_CHECK with BOOST_REQUIRE.

When GUI Coin Control has selected UTXOs, this unconditional exclusion also affects GetAvailableBalance(), not just automatic coin selection. SendCoinsDialog::send() passes a coin-control copy with m_allow_other_inputs=false, and WalletModel::prepareTransaction() checks getAvailableBalance(coinControl) before creating the transaction; therefore, if the selected coins hold the funds but the unselected set does not, the GUI reports AmountExceedsBalance and cannot spend them. The “use available balance” button likewise derives its amount from the unselected coins. Preserve the selected-only balance behavior or account for preset inputs separately.

…pre-set-inputs fetching responsibility from Coin Selection 3fcb545 bench: benchmark transaction creation process (furszy) a8a7534 wallet: SelectCoins, return early if target is covered by preset-inputs (furszy) f41712a wallet: simplify preset inputs selection target check (furszy) 5baedc3 wallet: remove fetch pre-selected-inputs responsibility from SelectCoins (furszy) 295852f wallet: encapsulate pre-selected-inputs lookup into its own function (furszy) 37e7887 wallet: skip manually selected coins from 'AvailableCoins' result (furszy) 94c0766 wallet: skip available coins fetch if "other inputs" are disallowed (furszy) Pull request description: #### # Context (Current Flow on Master) In the transaction creation process, in order to select which coins the new transaction will spend, we first obtain all the available coins known by the wallet, which means walking-through the wallet txes map, gathering the ones that fulfill certain spendability requirements in a vector. This coins vector is then provided to the Coin Selection process, which first checks if the user has manually selected any input (which could be internal, aka known by the wallet, or external), and if it does, it fetches them by searching each of them inside the wallet and/or inside the Coin Control external tx data. Then, after finding the pre-selected-inputs and gathering them in a vector, the Coin Selection process walks-through the entire available coins vector once more just to erase coins that are in both vectors. So the Coin Selection process doesn’t pick them twice (duplicate inputs inside the same transaction). #### # Process Workflow Changes Now, a new method, `FetchCoins` will be responsible for: 1) Lookup the user pre-selected-inputs (which can be internal or external). 2) And, fetch the available coins in the wallet (excluding the already fetched ones). Which will occur prior to the Coin Selection process. Which allows us to never include the pre-selected-inputs inside the available coins vector in the first place, as well as doing other nice improvements (written below). So, Coin Selection can perform its main responsibility without mixing it with having to fetch internal/external coins nor any slow and unneeded duplicate coins verification. #### # Summarizing the Improvements: 1) If any pre-selected-input lookup fail, the process will return the error right away. (before, the wallet was fetching all the wallet available coins, walking through the entire txes map, and then failing for an invalid pre-selected-input inside SelectCoins) 2) The pre-selected-inputs lookup failure causes are properly described on the return error. (before, we were returning an "Insufficient Funds" error for everything, even if the failure was due a not solvable external input) 3) **Faster Coin Selection**: no longer need to "remove the pre-set inputs from the available coins vector so that Coin Selection doesn't pick them" (which meant to loop-over the entire available coins vector at Coin Selection time, erasing duplicate coins that were pre-selected). Now, the available coins vector, which is built after the pre-selected-inputs fetching, doesn’t include the already selected inputs in the first place. 4) **Faster transaction creation** for transactions that only use manually selected inputs. We now will return early, as soon as we finish fetching the pre-selected-inputs and not perform the resources expensive calculation of walking-through the entire wallet txes map to obtain the available coins (coins that we will not use). --------------------------- Added a new bench (f6d0bb2) measuring the transaction creation process, for a wallet with ~250k UTXO, only using the pre-selected-inputs inside coin control. Setting `m_allow_other_inputs=false` to disallow the wallet to include coins automatically. #### Result on this PR (tip f6d0bb2d): | ns/op | op/s | err% | total | benchmark |--------------------:|--------------------:|--------:|----------:|:---------- | 1,048,675.00 | 953.58 | 0.3% | 0.06 | `WalletCreateTransaction` vs #### Result on master (tip 4a4289e): | ns/op | op/s | err% | total | benchmark |--------------------:|--------------------:|--------:|----------:|:---------- | 96,373,458.20 | 10.38 | 0.2% | 5.30 | `WalletCreateTransaction` The benchmark took to run in master: **96.37 milliseconds**, while in this PR: **1 millisecond** 🚀 .

Which, on every wallet decryption call, forces the process to re-write all the ckeys to db when it's not needed. Note: The first commit fixes the issue, the two commits in the middle are cleanups so `DuplicateMockDatabase` can be used without duplicating code. And, the last one is pure test coverage for the crypted keys loading process. Includes test coverage for the following scenarios: 1) "All ckeys checksums valid" test: Loads an encrypted wallet with all the crypted keys with a valid checksum and verifies that 'CWallet::Unlock' doesn't force an entire crypted keys re-write. (we force a complete ckeys re-write if we find any missing crypted key checksum during the wallet loading process) 2) "Missing checksum in one ckey" test: Verifies that loading up a wallet with, at least one, 'ckey' with no checksum triggers a complete re-write of the crypted keys. 3) "Invalid ckey checksum error" test: Verifies that loading up a ckey with an invalid checksum stops the wallet loading process with a corruption error. 4) "Invalid ckey pubkey error" test: Verifies that loading up a ckey with an invalid pubkey stops the wallet loading process with a corruption error.

…ontaining legacy key type entries 3198e42 test: check that loading descriptor wallet with legacy entries throws error (Sebastian Falbesoner) 349ed2a wallet: throw error if legacy entries are present on loading descriptor wallets (Sebastian Falbesoner) Pull request description: Loading a descriptor wallet currently leads to a segfault if a legacy key type entry is present that can be deserialized successfully and needs SPKman-interaction.

On a descriptor wallet, creating that (via method `GetOrCreateLegacyScriptPubKeyMan`) fails and then leads to a null-pointer dereference crash. E.g. for CSCRIPT: https://github.com/bitcoin/bitcoin/blob/50422b770a40f5fa964201d1e99fd6b5dc1653ca/src/wallet/walletdb.cpp#L589-L594 ~~This PR fixes this by simply ignoring legacy entries if the wallet flags indicate that we have a descriptor wallet. The second commits adds a regression test to the descriptor wallet's functional test (fortunately Python includes sqlite3 support in the standard library).~~ ~~Probably it would be even better to throw a warning to the user if unexpected legacy entries are found in descriptor wallets, but I think as a first mitigation everything is obvisouly better than crashing. As far as I'm aware, descriptor wallets created/migrated by Bitcoin Core should never end up in a state containing legacy type entries though.~~ This PR fixes this by throwing an error if legacy entries are found in descriptor wallets on loading.

First Issue Description (bitcoin-core/gui#688): The previous behavior for `getAvailableBalance`, when the coin control had selected coins, was to return the sum of them. Instead, we are currently returning the wallet's available total balance minus the selected coins total amount. Reason: Missed to update the `GetAvailableBalance` function to include the coin control selected coins on bitcoin#25685. Context: Since bitcoin#25685 we skip the selected coins inside `AvailableCoins`, the reason is that there is no need to waste resources walking through the entire wallet's txes map just to get coins that could have gotten by just doing a simple `mapWallet.find`). Places Where This Generates Issues (only when the user manually select coins via coin control): 1) The GUI balance check prior the transaction creation process. 2) The GUI "useAvailableBalance" functionality. Note 1: As the GUI uses a balance cache since bitcoin-core/gui#598, this issue does not affect the regular spending process. Only arises when the user manually select coins. Note 2: Added test coverage for the `useAvailableBalance` functionality. ---------------------------------- Second Issue Description (bitcoin#26687): As we are using a cached balance on `WalletModel::getAvailableBalance`, the function needs to include the watch-only available balance for wallets with private keys disabled.
