From b5ed6e45d713fcda53817b4f86287b22467b7847 Mon Sep 17 00:00:00 2001 From: Lukasz Klimek <842586+lklimek@users.noreply.github.com> Date: Mon, 27 Apr 2026 12:47:07 +0200 Subject: [PATCH 01/52] feat(rs-platform-wallet): add address_derivation_info and fee_paid accessors Two small public-API additions feeding the upcoming e2e harness: - `PlatformAddressWallet::address_derivation_info(addr)` returns the DIP-17 `(account_index, key_class, key_index)` for an address owned by the wallet, exposed via a new `AddressDerivationInfo` struct. Lets external `Signer` impls re-derive the matching ECDSA private key from the seed without poking at internal locks. - `PlatformAddressChangeSet::fee_paid()` returns the credits burned by the transfer that produced the changeset, computed as `inputs_consumed - outputs_credited` at construction time. A new `fee_paid: Credits` field on the changeset retains the value; `Merge::merge` accumulates it (saturating-add) and `is_empty` considers it. Sync-only changesets keep `fee_paid == 0`.

The framework validates platform-address credit operations through +the same `PlatformWalletManager` and `dash-sdk` layers used by production applications. + +The design is modelled on `dash-evo-tool/tests/backend-e2e/`, with one important +difference in funding strategy: where DET uses Core asset locks to move value from +Layer 1 to Platform, this framework uses a **platform-address bank wallet** that +already holds credits.

If that lock is already held it tries up to 10 numbered slot +directories (`-1`, `-2`, ...). A slot holds the SPV block cache, +the SDK config, and the test-wallet registry independently from every other slot. + +**Per-environment bank mnemonics** — two processes that share a mnemonic but land on +different slots will still conflict at the network level (duplicate nonces). The +correct isolation strategy is to give each CI environment its own distinct +`PLATFORM_WALLET_E2E_BANK_MNEMONIC`. The framework documents this requirement but +cannot enforce it across machines. + +Typical CI setup: + +```bash +# Branch A job +PLATFORM_WALLET_E2E_BANK_MNEMONIC="$BANK_MNEMONIC_BRANCH_A" cargo test ... + +# Branch B job (different secret) +PLATFORM_WALLET_E2E_BANK_MNEMONIC="$BANK_MNEMONIC_BRANCH_B" cargo test ... +``` + +--- + +## Panic-safe cleanup + +Every test wallet is registered in a JSON file at `/test_wallets.json` +**before** the test starts — not after. If a test panics, the wallet's seed remains in +the registry so the next run can recover it. + +### Happy path + +`setup_guard.teardown()` is the explicit, recommended path: + +1. Syncs the test wallet's balances. +2. Transfers any remaining credits back to the bank's primary address. +3. Waits for the bank to observe the incoming credits (60 s timeout). +4. Removes the wallet entry from the registry and de-registers it from the manager. + +### Panic path + +If `teardown()` is not called — because the test panicked or returned early — the +`SetupGuard` `Drop` implementation logs a warning: + +``` +SetupGuard dropped without explicit teardown — wallet +will be swept on next test process startup +``` + +The wallet entry stays in `test_wallets.json`. On the next run, the startup sweep +(`sweep_orphans`) iterates all registry entries, reconstructs each wallet from its +stored seed, syncs, and transfers remaining credits back to the bank. Successfully +swept wallets are removed from the registry; wallets that fail to sweep (transient +network error) are marked `Failed` and retried on the following run. + +The registry uses atomic writes (write to a temp file, then rename) to avoid +corruption from mid-write crashes. + +--- + +## Troubleshooting + +- **Bank under-funded** — Initialization panics with the bank's receive address and + the current balance. Top up the printed address from any testnet wallet and re-run. + The minimum threshold is controlled by `PLATFORM_WALLET_E2E_MIN_BANK_CREDITS` + (default 100 000 000 credits). + +- **SPV sync timeout** — Startup waits up to 60 seconds for the masternode list to + sync. If it times out, testnet peers may be temporarily unreachable. Check network + connectivity and try again; the block cache in the workdir slot will make the next + attempt faster. Setting `RUST_LOG=debug` shows which peers the SPV client is + connecting to. + +- **Workdir slot exhausted** — If all 10 slots are locked, initialization fails with: + `No available workdir slots (tried 0..10)`. This typically means 10+ concurrent + processes are running against the same `PLATFORM_WALLET_E2E_WORKDIR` base. Either + wait for other processes to finish, remove stale lock files from the slot directories + (`rm */.lock`), or set `PLATFORM_WALLET_E2E_WORKDIR` to a distinct path per + environment. + +- **Test panicked — registry not cleared** — On the next run, the startup sweep log + will report `swept N wallets from previous panicked run`. This is expected behavior. + If the sweep itself fails (the orphaned wallet has no balance, or the network is + unavailable), the entry is marked `Failed` and retried on the following run. Entries + with a `Failed` status do not block test execution. + +--- + +## Future Core support + +The directory is intentionally named `e2e/` rather than `platform_e2e/`. Once the +wallet's SPV-driven Core operations (UTXO selection, transaction broadcast, asset +locks) are stable enough to test end-to-end, Core-feature tests will live alongside +the existing platform-address tests under `tests/e2e/cases/core/`. + +SPV is already started at framework initialization — a `SpvRuntime` is running for +the lifetime of the test process, and `SpvContextProvider` is wired to bridge +quorum-key lookups into the SDK. Future identity and Core tests get proof verification +for free without changing the initialization sequence. + +--- + +## Architecture quick reference + +The framework initializes once per test-binary process.

Every public surface returns `FrameworkError::NotImplemented` and is documented to point at the wave that will wire it. Layout (`tests/e2e/`): - framework/{mod,config,harness,workdir,panic_hook,wait,persistence} - cases/mod.rs (empty, ready for Wave 4 `pub mod transfer;`) `tests/e2e.rs` uses `#[path = ...]` on the top-level `cases` / `framework` mods because the integration-test crate root would otherwise resolve submodules under `tests/` rather than `tests/e2e/`. Cargo.toml dev-deps added: tokio-shared-rt, tempfile, dotenvy, bip39, fs2, simple-signer (path), parking_lot, tokio-util with `rt` feature for `CancellationToken`. async-trait + serde_json already in `[dependencies]` and visible to tests. `cargo check --tests`, `cargo clippy --tests -- -D warnings`, and `cargo fmt` are all clean.

ECDSA secrets cached in a `parking_lot::Mutex` so the critical section stays sync. - `bank.rs` — `BankWallet::load` parses the BIP-39 mnemonic, registers the wallet via the manager, runs a single BLAST sync, captures the primary receive address for log breadcrumbs, and PANICS with an actionable message if the balance falls below `Config::min_bank_credits`. `fund_address` serialises through a static `tokio::sync::Mutex` so concurrent in-process funding calls don't race nonces. - `wallet_factory.rs` — `TestWallet` factory + `SetupGuard` with a Drop-warning panic-safety fallback. Default account/key-class match `WalletAccountCreationOptions::Default` (account 0, key_class 0). - `registry.rs` — `PersistentTestWalletRegistry` JSON-backed under `/test_wallets.json`. In-memory keys are `[u8; 32]`; on-disk keys are hex-encoded (JSON requires string keys). Atomic write-temp + rename. Corrupt files fall back to empty with a `tracing::warn!`. Unit tests cover round-trip + corrupt- file recovery. - `cleanup.rs` — `sweep_orphans` (startup) reconstructs every registry entry, syncs, drains above-dust balances back to the bank's primary receive address. `teardown_one` is the per-test variant called by `SetupGuard::teardown`. Best-effort: failures log + retain the registry entry so the next startup retries. `framework/mod.rs` grows the `FrameworkError` enum with `Io` / `Wallet` / `Bank` / `Cleanup` variants and registers the five new submodules. The Wave 2 placeholder `SetupGuard` is replaced with `pub use wallet_factory::SetupGuard;` so test authors and the `prelude` re-export both resolve to the real type. `SetupGuard::teardown` itself is intentionally still a stub returning `NotImplemented` — Wave 4 wires it to `E2eContext::{manager, bank, registry}()` accessors that don't exist yet (those land alongside Wave 3b's SDK/SPV/ContextProvider work). Concrete implementation lives in `cleanup::teardown_one`, which takes the resources explicitly, so Wave 4 just threads them through. Cargo.toml dev-deps add `serde = { version = "1", features = [ "derive"] }` for the registry's JSON shape. `cargo check --tests`, `cargo clippy --tests -- -D warnings`, `cargo fmt`, and the in-binary registry unit tests (3/3) all pass.

DAPI addresses come from `Config::dapi_addresses` or, for testnet, the same hard-coded peer list used in `tests/spv_sync.rs`. Bootstraps with `NoopContextProvider` so harness init can build the SDK before SPV is ready; harness then live-swaps the provider via `Sdk::set_context_provider` (backed by `ArcSwap`, so no rebuild needed — Risk #3 from the plan resolved). - `framework/spv.rs`: `start_spv` spawns the SPV runtime in the background under the workdir slot's storage path with full validation + bloom-filter mempool tracking + testnet P2P seed peers. `wait_for_mn_list_synced` polls `SpvRuntime::sync_progress` until the masternode-list manager reports `SyncState::Synced`, with a configurable timeout. - `framework/context_provider.rs`: `SpvContextProvider` wraps `Arc` and bridges async->sync quorum-key lookups via `tokio::task::block_in_place` + `Handle::block_on`. Module docs flag the multi-thread runtime requirement. Data contracts and token configurations defer to SDK network fetch (`Ok(None)`); the activation height is a documented placeholder pending a `SpvRuntime` accessor (`TODO(Wave5)`). `mod.rs` gets the three `pub mod` declarations needed to compile the new files; no other wiring touched (Wave 4 owns the integration into `setup`/`E2eContext`). Errors temporarily flow through the existing `FrameworkError::NotImplemented` static-string variant with real diagnostic detail logged via `tracing::error!` — Wave 4 adds richer variants when it reconciles bank/registry/cleanup wiring. cargo check + clippy (-D warnings) + fmt all clean.

Framework integration (`framework/`): - `harness.rs` — full `E2eContext::init` body. `OnceCell`-backed process singleton runs Config -> workdir slot -> panic hook -> SDK build -> manager construction -> SPV start -> wait_for_mn_list_synced -> live `set_context_provider` swap to `SpvContextProvider` -> bank load -> registry open -> startup `cleanup::sweep_orphans`. Adds `manager()` / `bank()` / `registry()` / `spv()` / `cancel_token()` accessors. Internal `NoopEventHandler` satisfies `PlatformEventHandler`. - `mod.rs::setup` — wires the `OnceCell` init + `TestWallet` creation + registry insert. Registry write happens BEFORE returning the guard so a panic mid-test still surfaces to the next process startup's sweep. - `wallet_factory::SetupGuard::teardown` — now forwards to `cleanup::teardown_one(ctx.manager(), ctx.bank(), ctx.registry(), &test_wallet)`. Sets `teardown_called = true` on success so `Drop` doesn't emit a spurious warning. - `config::Config::from_env` — real `dotenvy` + env-var loader with documented defaults. New `DEFAULT_MIN_BANK_CREDITS` const pulled out of the `Default` impl. - `workdir::pick_available_workdir` — real `flock` slot-fallback loop with `MAX_SLOTS = 10`. Slot 0 IS ``; higher slots are `-N`. Includes a unit test that demonstrates the fall-through behaviour with a held lock. - `panic_hook::install` — installs the cancellation hook (via `take_hook` + `set_hook`) idempotently; preserves the previously-installed hook so test output isn't suppressed. - `wait::{wait_for, wait_for_balance}` — real poll-with-timeout loop on a 500ms interval. `wait_for_balance` runs a fresh `sync_balances` each round and treats sync errors as transient (debug-log + retry). - `bank.rs` — adds `BankWallet::network()` accessor used by `harness::build` and `cleanup::sweep_orphans`. Test case (`cases/transfer.rs`): - `transfer_between_two_platform_addresses` — `#[ignore]`-gated `#[tokio_shared_rt::test(shared)]`. Bank funds `addr_1` with 50_000_000 credits; test wallet self-transfers 10_000_000 to `addr_2`; asserts both balances against `cs.fee_paid()` (the Wave-1 accessor); explicit `s.teardown()` sweeps remaining funds back to the bank. Verification (no live testnet): - `cargo check --tests -p platform-wallet` OK - `cargo clippy --tests -p platform-wallet -- -D warnings` OK - `cargo fmt -p platform-wallet` OK - `cargo test -p platform-wallet --test e2e` 4/4 passed, 1 ignored (the network-bound transfer test) - `cargo test -p platform-wallet --test e2e -- --ignored --list` prints exactly one test - `cargo test -p platform-wallet --lib` 110/110 Live testnet run is the operator's job: pre-fund the bank wallet named by PLATFORM_WALLET_E2E_BANK_MNEMONIC and run `cargo test --test e2e -- --ignored --nocapture`.

QA-005 (LOW): - `framework/bank.rs` — under-funded panic now matches the README's friendlier multi-line format and prints the bech32m address (`PlatformAddress::to_bech32m_string(network)`, e.g. `tdash1q...` on testnet) instead of the `Debug` `P2pkh([1, 2, ...])` form. Operators see the same shape in the README's "Bank pre-funding" section and at runtime. QA-009 (LOW): - `framework/cleanup.rs` — replace three `let _ = manager.remove_wallet(...)` sites (sweep-dust path, post-sweep, teardown) with `if let Err(err) = ... { tracing::warn!(...) }`. Failures previously silent now surface in CI logs so operators can spot leaked manager state (e.g. SPV still tracking a wallet's addresses on subsequent passes). Verification: - `cargo check --tests -p platform-wallet` OK - `cargo clippy --tests -p platform-wallet -- -D warnings` OK - `cargo fmt -p platform-wallet` OK - `cargo test -p platform-wallet --test e2e` 4/4 + 1 ignored - `cargo test -p platform-wallet --test e2e -- --ignored --list` shows `transfer_between_two_platform_addresses` Live-testnet verification still owned by operator with a pre-funded `PLATFORM_WALLET_E2E_BANK_MNEMONIC` — see the remaining `TODO(qa-wave5)` at the top of `cases/transfer.rs`. Deferred per team-lead's brief: - QA-002 (plan doc drift) — memcan lesson at wrap. - QA-003 (hard-coded sweep fee) — design discussion. - QA-006 (dead persistence.rs stub) — next maintenance pass. - QA-007 (permissive can_sign_with) — current behaviour is acceptable for current tests. - QA-008 (placeholder activation height) — TODO comment is sufficient until Core feature tests need it.

The helper handles three scenarios: - No active tokio runtime: creates a temporary current-thread runtime for the call. - Current-thread runtime (the `tokio_shared_rt::test` default): spawns a dedicated OS thread with a sync_channel bridge — sidesteps the `block_in_place` panic Marvin reproduced live. - Multi-thread runtime: uses `block_in_place + spawn`, the optimal path. With this in place the e2e harness works on every tokio flavor; the `flavor = "multi_thread"` attribute in `cases/transfer.rs` (landed in the prior wave-6 commit) is now defense-in-depth + parity with `dash-evo-tool/tests/backend-e2e/`, no longer load-bearing for correctness. `Cargo.toml` dev-deps gain `dash-async = { path = "../rs-dash-async" }`.

Calling it twice back-to-back BEFORE any sync therefore returns the same address — the cursor hasn't moved. Reorder `cases/transfer.rs` so addr_2 is derived AFTER `wait_for_balance(&test_wallet, &addr_1, ...)` lands. The BLAST sync inside `wait_for_balance` marks addr_1 used; the next derivation then lands on a fresh slot. Side benefit: the test now also exercises the wallet's "observe inbound funds + advance address pool" property as a happy-path invariant. Updated the per-step comments and the module-level "Flow" docstring to match the new ordering. The `assert_ne!` message now reads "wallet must hand out a fresh address once addr_1 is observed used" — phrasing matches the post-fix invariant. Also refreshed an outdated comment block above the `#[tokio_shared_rt::test(...)]` attribute. Wave 7 swapped the SpvContextProvider bridge to `dash_async::block_on`, so the multi-thread flavor is no longer load-bearing for correctness; it stays for parity with `dash-evo-tool/tests/backend-e2e/` and because it gives the optimal `block_in_place + spawn` path.

With a bank holding ~500B credits and a 50M output, the SDK got `inputs = {bank: 499_985_086_740}, outputs = {target: 50_000_000}` and the protocol rejected because address-funds-transfer enforces `Σ inputs.credits == Σ outputs.credits` (verified at `rs-dpp/.../address_funds_transfer_transition/v0/state_transition_validation.rs`). The protocol's actual semantics (confirmed by the on-chain test `rs-drive-abci/.../address_funds_transfer/tests.rs::test_input_balance_decreased_correctly`, asserting `new_balance == initial_balance - transfer_amount - fee`): - `inputs[addr].credits` = consumed amount from `addr` - `outputs[addr]` = credited amount to `addr` - `Σ inputs.credits == Σ outputs.credits` (strict equality) - Fee is deducted from the targeted input address's REMAINING balance (post-consumption), per `AddressFundsFeeStrategy` (`DeductFromInput(0)` reduces the *remaining balance* by the fee — never the inputs map's `Credits` value) Fix: extract the selection loop into a pure module-scope helper `select_inputs(candidates, outputs, total_output, fee_strategy, platform_version)` that: 1. Walks candidates in DIP-17 order, tentatively adding each at its full balance to drive the per-iteration fee estimate. 2. Stops when `accumulated >= total_output + estimated_fee` (the accumulated balance must be enough to also pay the fee from the last input's remaining balance). 3. Trims the LAST included input down to `total_output - prior_accumulated` so `Σ inputs.credits == total_output`. 4. If the trim is 0 (corner case where prior inputs alone covered total_output but didn't leave enough margin for the fee margin), drops the last address — the fee gets paid out of the preceding input's remaining-balance margin instead of forcing a `min_input_amount` violation. Side benefits of the refactor: - The pure helper is unit-testable without constructing a full `PlatformWalletManager` + `PlatformAddressWallet`. Four new tests in `auto_select_tests` cover the fix: - `single_input_oversized_balance_trims_to_output_amount` — the regression test for the Wave-8 live failure (bank with way more than needed). Asserts `selected[addr] == total_output` (NOT full balance and NOT total_output + fee, the latter being a common misconception). - `two_input_selection_trims_only_the_last` — trims only the last input when two are needed; first consumed in full, second trimmed to bring sum to `total_output`. - `insufficient_balance_errors` — descriptive error path. - `no_candidates_errors` — empty input set returns error rather than panicking. - The full per-`PlatformAddressWallet` async method `auto_select_inputs` now just gathers `(address, balance)` candidates and calls `select_inputs`, which keeps the testability win without changing public API. Doc note in `auto_select_inputs_for_withdrawal` clarifying the asymmetry: withdrawal validates `Σ inputs > output_amount` (strictly greater, surplus = fee), so its drain-everything strategy is correct by design — NOT the same bug as the transfer selector. No code change there. Verification: - `cargo check --tests -p platform-wallet` OK - `cargo clippy --tests -p platform-wallet -- -D warnings` OK - `cargo fmt -p platform-wallet` OK - `cargo test -p platform-wallet --lib` 114/114 (110 existing + 4 new) Live e2e retest pending.

The hub fans SPV sync, network, wallet, and platform-address-sync events out to a `tokio::sync::Notify`. Test wallets clone an `Arc` from the `E2eContext` and `wait_for_balance` now awaits on the hub instead of polling on a fixed 500ms interval. The loop captures a `Notified` future BEFORE running `sync_balances`, so notifications arriving mid-sync aren't dropped. A `BACKSTOP_WAKE_INTERVAL` of 2s caps each await, keeping forward progress on idle-chain / no-peer scenarios where no events fire. The generic `wait_for` helper is unchanged — it stays polling-based for conditions outside the event hub's reach.

This commit reverts every Wave 1 / 4 / 6 production-code change EXCEPT Wave 9's `auto_select_inputs` trim (which is a real upstream bug fix) and absorbs the dependency on those reverted accessors inside the e2e test framework. Reverted in production code (now identical to origin/v3.1-dev): - `PlatformAddressChangeSet::fee_paid` field, accessor, `Merge::merge` accumulator, and `is_empty` branch (`src/changeset/changeset.rs`). - `fee_paid` capture / computation at construction (`src/wallet/platform_addresses/transfer.rs`'s `transfer` method body — auto_select trim KEPT). - `PlatformAddressWallet::address_derivation_info` accessor and the new `AddressDerivationInfo` struct (`src/wallet/platform_addresses/wallet.rs`). - Supporting `lookup_p2pkh` helper on `PlatformPaymentAddressProvider` (`src/wallet/platform_addresses/provider.rs`). - Re-exports of `AddressDerivationInfo` from `src/wallet/platform_addresses/mod.rs`, `src/wallet/mod.rs`, `src/lib.rs`. - Doc-comment block on `auto_select_inputs_for_withdrawal` explaining the protocol asymmetry — useful, but additive production-code change beyond the Wave-9 trim, so reverted to match the team-lead's "ONLY Wave 9's auto_select_inputs trim" gate. Kept in production code: - Wave 9's `auto_select_inputs` trim in `src/wallet/platform_addresses/transfer.rs` (real upstream bug fix discovered via the live e2e run; trims the last selected input down to the consumed amount so `Σ inputs.credits == Σ outputs.credits` holds. Includes the pure `select_inputs` helper + 4 unit tests.). Test-framework absorbs the dependency: `tests/e2e/framework/signer.rs` — completely rewritten: - `SeedBackedPlatformAddressSigner::new(&seed_bytes, network)` (and `new_with_gap` for explicit gap-window control) eagerly pre-derives every clear-funds platform-payment key in `0..gap_limit` (default 20) via the DIP-17 path `m/9'/coin_type'/17'/0'/0'/index`, computes each address (RIPEMD160(SHA256(compressed pubkey))), and stores `[u8; 32]` ECDSA secrets keyed by the 20-byte address hash. - `sign(addr, data)` → synchronous `HashMap` lookup → SimpleSigner- shape `dashcore::signer::sign`. No async wallet round-trip on the hot path. - `can_sign_with(addr)` is now a HONEST cache check (resolves Marvin's QA-007 deferred finding as a side effect — no more permissive `true` for any P2PKH). `tests/e2e/framework/bank.rs` — `BankWallet::load` now derives the 64-byte seed from the BIP-39 mnemonic via `Mnemonic::to_seed("")` and passes it to the seed-backed signer constructor. `tests/e2e/framework/wallet_factory.rs` — `TestWallet::create` already had `seed_bytes: [u8; 64]` in its signature; threading it into the new signer constructor was a one-line swap. `tests/e2e/framework/cleanup.rs` — `sweep_one` already parses `seed_bytes` from the registry's `seed_hex`; passes them into the new signer constructor. `tests/e2e/cases/transfer.rs` — fee assertion switches from `cs.fee_paid()` to balance-delta derivation (`fee = FUNDING_CREDITS - received - remaining`), with `assert!(fee > 0)` and `assert!(fee < TRANSFER_CREDITS)` bounding plausibility. The `cs` binding is dropped (transfer's return value is no longer needed for assertions). A debug `tracing::info!` log records the observed fee for operator visibility. `tests/e2e/README.md` — canonical example updated to match the balance-delta fee derivation. `book/src/sdk/wallet.md` — verified clean, no references to `fee_paid` / `address_derivation_info` to remove. Verification: - `cargo check -p platform-wallet --tests` OK - `cargo clippy -p platform-wallet --tests -- -D warnings` OK - `cargo fmt -p platform-wallet` OK - `cargo test -p platform-wallet --test e2e` 4 passed + 1 ignored - `cargo test -p platform-wallet --test e2e -- --ignored --list` shows `transfer_between_two_platform_addresses` - `git diff origin/v3.1-dev -- src/` ONLY `transfer.rs` (Wave 9's auto_select_inputs trim — 269+/42-) - `cargo test -p platform-wallet --lib` pre-revert the lib added 4 auto_select_tests; those are still in transfer.rs and pass (114 lib tests total) Live retest pending Claudius — with the new seed-backed signer the test should now (a) produce a working bank signer (50M funding transfer), (b) produce a working test-wallet signer (10M self-transfer), (c) derive the fee from observed balances and pass the new bound assertions. Resolves: QA-007 (`can_sign_with` honesty) as a side benefit.

Investigation: - The wait predicate (`MasternodesProgress::state() == Synced`) is correct — the dash-spv `MasternodesManager` reaches `Synced` at the end of `verify_and_complete()` once the QRInfo + non-rotating quorum verification pipeline drains. New blocks after that drive incremental updates *while staying in `Synced`*, so the predicate is reachable on a live network. - DET's `wait_for_spv_running` checks the `SpvStatus::Running` flag set after `SyncEvent::SyncComplete` fires — same underlying signal, just exposed via app-level state. - The `tests/spv_sync.rs` integration test uses a 600s timeout for the same cold-cache scenario; the 180s `SPV_READY_TIMEOUT` baked into the harness was simply too short for ~1.4M+ headers + ~3.6M filters + a full QRInfo round-trip on a fresh cache. Root cause classification: (b) — predicate correct, timeout too short. Fix, scoped to `framework/spv.rs` only: - Lift the effective timeout to `timeout.max(600s)` via a `COLD_CACHE_TIMEOUT_FLOOR` constant. Larger caller-supplied timeouts still pass through unchanged. - Drop the polling interval to 500ms so the wait reacts faster once mn-list flips to `Synced`. - Emit `info`-level pipeline snapshots every 30s (and once on timeout) summarising headers / filter-headers / filters / masternodes state, current and target heights — so future cold-run hangs are debuggable from default logs. - Track `(state, height)` together for the per-change debug log so `WaitForEvents → WaitingForConnections → Syncing → Synced` transitions are visible even when current_height stays at 0. Production code is untouched (Wave 11 territory). No new dependency on `WaitEventHub` — the existing 500ms poll is responsive enough now that the timeout floor is realistic.

Wave 4 wired `NoPlatformPersistence` directly inside `harness::E2eContext::build` instead, leaving the stub orphaned. Marvin's QA pass flagged it as dead-code in QA-006; this commit drops it. - `tests/e2e/framework/persistence.rs` removed. - `pub mod persistence;` declaration in `framework/mod.rs` removed alongside its prelude bullet in the module-level docs. No callers to update — confirmed via `grep -rn "TestPersister\|persistence::" tests/e2e/` returning zero hits before / after. QA-008 — document the testnet-only activation-height assumption: - `framework/context_provider.rs`: replace the `TODO(Wave5)` placeholder block on the activation-height constant with explicit rustdoc explaining WHY hard-coding `0` is safe-by-position for the e2e framework's testnet-only scope (mn_rr activation on testnet is past every height the platform-address transfer flow exercises; the verification path that consumes this value never compares against an unactivated quorum). Constant renamed `PLACEHOLDER_ACTIVATION_HEIGHT` → `PLATFORM_ACTIVATION_HEIGHT_TESTNET_SAFE` so the assumption shows up at the use-site too. Forward-looking pointer for future tests retained: surface the real value via `SpvRuntime` and wire it through if a Core / mainnet path needs it. - `cases/transfer.rs`: new `# Testnet assumption` section in the module-level `//!` docs flags that the test depends on the hard-coded activation height being safe-by-position, with a pointer back to the rationale in the `context_provider` constant docs. Verification (offline): - `cargo check -p platform-wallet --tests` OK - `cargo clippy -p platform-wallet --tests -- -D warnings` OK - `cargo fmt -p platform-wallet` OK - `cargo test -p platform-wallet --test e2e -- --ignored --list` shows `transfer_between_two_platform_addresses` - 4 files touched: 3 modified (`mod.rs`, `context_provider.rs`, `cases/transfer.rs`), 1 deleted (`persistence.rs`). No production-code (`src/`) changes — the diff against `origin/v3.1-dev -- packages/rs-platform-wallet/src/` remains exactly the Wave 9 `auto_select_inputs` trim in `transfer.rs`, no other production-code drift.

This delivers fast and reliable testnet runs while the SPV cold-start path stabilizes (Task #15). Cargo.toml dev-deps gain `rs-sdk-trusted-context-provider = { path = "../rs-sdk-trusted-context-provider" }`. `framework/sdk.rs`: - `build_sdk` now installs `TrustedHttpContextProvider` directly via `SdkBuilder::with_context_provider`. No more `NoopContextProvider` placeholder + later `set_context_provider` swap. - New helper `build_trusted_context_provider` honours the optional `Config::trusted_context_url` override (`PLATFORM_WALLET_E2E_TRUSTED_CONTEXT_URL` env var) and falls back to the network-builtin URL via `TrustedHttpContextProvider::new`. Cache size: 256 entries (LRU; the provider only allocates on a miss). - `NoopContextProvider` impl removed (no longer needed). `framework/config.rs`: - `trusted_context_url: Option` field added with `None` default. - `vars::TRUSTED_CONTEXT_URL` constant added. - `from_env` parses the new env var with whitespace-trim and empty-string filter. `framework/harness.rs`: - SPV start + readiness wait + ctx-provider live-swap blocks COMMENTED OUT — not deleted — with a clear marker block showing exactly what to uncomment when SPV stabilises (the `SPV_READY_TIMEOUT` const, the `spv` / `context_provider` imports, the `start_spv` / `wait_for_mn_list_synced` / `set_context_provider` calls). - `E2eContext::spv_runtime` field changed from `Arc` to `Option>` (current default `None`). Keeps the field shape so future Core-feature tests don't churn signatures when SPV returns; the `spv()` accessor returns `Option<&Arc>` accordingly. - Module-level `//!` docs rewritten to reflect the new init order (no SPV step) plus a "SPV-based context provider — currently disabled" section. `framework/spv.rs`, `framework/context_provider.rs`: - Top-level `//! NOTE` headers added flagging the modules as currently disabled in favour of `TrustedHttpContextProvider`, with a pointer to harness.rs's commented-out wiring and the Task #15 re-enablement path. - Modules stay compilable; the framework's existing `#![allow(dead_code)]` (mod.rs:35) covers the unused symbols without per-item annotations. `tests/e2e/README.md`: - New "Context provider" section explaining the `TrustedHttpContextProvider` default and the `PLATFORM_WALLET_E2E_TRUSTED_CONTEXT_URL` override (with a ready-to-paste shell example). - New "Deferred" section listing SPV-based context provider (Task #15) with a pointer to the harness.rs commented block. - "Future Core support" section updated: when Task #15 lands, `SpvRuntime` will run for the test process lifetime and `SpvContextProvider` will be live-swapped after mn-list sync; the public test API stays unchanged. - Env-var table gains `PLATFORM_WALLET_E2E_TRUSTED_CONTEXT_URL` row. Verification (offline): - `cargo check -p platform-wallet --tests` OK - `cargo clippy -p platform-wallet --tests -- -D warnings` OK - `cargo fmt -p platform-wallet` OK - `cargo test -p platform-wallet --test e2e` 4 passed + 1 ignored - `cargo test -p platform-wallet --test e2e -- --ignored --list` shows `transfer_between_two_platform_addresses` Production-code diff against `origin/v3.1-dev` is unchanged (still exclusively Wave 9's `auto_select_inputs` trim in `transfer.rs`); this commit only touches dev-deps + e2e framework files + the e2e README. Live retest pending Claudius. With the trusted HTTP provider in place the harness should reach the bank load + balance check in seconds rather than the 95s cold-start SPV took, and the test body should run the full bank → fund → wait → transfer → assert → teardown loop.

Observed in early 2026: - 1-input → 1-output: ~9.55M credits - 2-input → 1-output: ~7.00M credits Bump `SWEEP_FEE_ESTIMATE` from 1M to 15M, comfortably covering 1-3 input scenarios. Bump `SWEEP_DUST_THRESHOLD` proportionally from 1M to 5M so the minimum-worth-sweeping total (`dust + fee = 20M`) recovers at least 5M net of fees rather than the implausible 1M of the old constants. Constant docs strengthened to: - Spell out the observed testnet fee bracket so future operators can sanity-check the value when retuning. - Cross-reference QA-003 (Marvin's deferred finding) and the long-term plan: lift the wallet's existing `transfer::estimate_fee_for_inputs` to a small public helper and call it from cleanup.rs, so the estimate stays accurate across protocol-version bumps. Tracked as a follow-up; until then bump the constant when testnet fee observations move beyond ~10M. No other behavior change. Build / clippy / fmt / test discovery all clean. Verification (offline): - `cargo check -p platform-wallet --tests` OK - `cargo clippy -p platform-wallet --tests -- -D warnings` OK - `cargo fmt -p platform-wallet` OK Live retest pending Claudius. The teardown sweep should now have the right margin to succeed in a single transition; combined with Wave 14's TrustedHttp provider, a full happy-path run is within reach.

When the caller's `total_output` was constructed from `SWEEP_FEE_ESTIMATE` but `auto_select` did its own (smaller) fee estimate, the resulting `Σ inputs` carried the auto-select estimate's leftover instead of the harness's, and the protocol's strict `Σ inputs == Σ outputs` check rejected the transition. Live observation: `inputs=30522500, outputs=25522500` — 5M off (auto_select's estimate, not the SWEEP_FEE_ESTIMATE). Fix: introduce `cleanup::drain_to_bank(&wallet, &signer, &bank_addr)` that uses `InputSelection::Explicit` so no trimming happens. The helper: 1. Snapshots non-zero balances for the wallet's default account. 2. Skips the sweep if total <= dust + fee_estimate (same gate as before). 3. Picks the LARGEST-balance address as the fee bearer (its remaining balance after consumption must cover the on-chain fee, so largest is the safest pick). 4. Builds `inputs_map`: every address contributes its full balance EXCEPT the fee bearer, which contributes `balance - SWEEP_FEE_ESTIMATE` so 15M stays at the fee bearer as the on-chain fee margin. 5. Computes the fee bearer's index in BTreeMap iteration order so `DeductFromInput(N)` targets the right input. (BTreeMap is sorted by `PlatformAddress`'s natural Ord, which matches what `deduct_fee_from_outputs_or_remaining_balance_of_inputs_v0` uses to index inputs.) 6. Calls `wallet.platform().transfer(account, Explicit(inputs_map), {bank: total_consumed}, [DeductFromInput(N)], …)`. `Σ inputs == Σ outputs` holds by construction (both equal `total - SWEEP_FEE_ESTIMATE`); the on-chain fee comes from the fee bearer's remaining balance via the strategy. Both `sweep_one` (orphan startup-sweep) and `teardown_one` (per-test happy-path) now route through the same helper: - `sweep_one` calls `drain_to_bank(&wallet, &signer, bank.primary_receive_address())` against the locally reconstructed wallet. - `teardown_one` calls `drain_to_bank(test_wallet.platform_wallet(), test_wallet.address_signer(), …)` — TestWallet exposes both via existing accessors, no new methods required. Edge case: the helper errors with a clear message if the fee-bearer's balance is below `SWEEP_FEE_ESTIMATE`. That only happens when a wallet's funds are so spread out across many small balances that no single address can cover the fee — outside the e2e test's normal distribution (max two addresses per test). Verification (offline): - `cargo check -p platform-wallet --tests` OK - `cargo clippy -p platform-wallet --tests -- -D warnings` OK - `cargo fmt -p platform-wallet` OK - `cargo test -p platform-wallet --test e2e` 4 passed + 1 ignored - `cargo test -p platform-wallet --lib auto_select_tests` 4/4 (Wave 9 unit tests still pass — `auto_select_inputs` itself unchanged; the cleanup paths simply don't go through it anymore) No production-code (`src/`) changes — production diff vs `origin/v3.1-dev` remains exactly Wave 9's `auto_select_inputs` trim. Cleanup-only fix in the test framework. Live retest pending Claudius. Both teardown and startup-sweep should now succeed: SDK gets matched `Σ inputs == Σ outputs` maps with explicit DeductFromInput targeting the fee bearer.

Observed protocol fees scale with input count: - 1-input → 1-output: ~9.55M credits (single-address transfer) - 2-input → 1-output: ~20.9M credits (Wave 17 live-observed) - 3-input → 1-output: ~30M credits (projected linear scaling) Each additional input adds witness + signature bytes that the fee schedule charges for. Wave 15's 15M margin covered only 1-input sweeps; the typical e2e teardown has 2 owned addresses (addr_1 with bank-funded balance + addr_2 from the self-transfer) and the 2-input fee blew past the 15M reserved. Bump `SWEEP_FEE_ESTIMATE` from 15M to 30M, which covers up to 3 inputs comfortably and exceeds the e2e test's normal distribution. The doc-comment on the constant is rewritten to spell out the observed / projected fee curve so future operators can sanity-check the value when retuning. `SWEEP_DUST_THRESHOLD` stays at 5M — the minimum-worth-sweeping total moves to `dust + fee = 35M` (recovers at least 5M net of fees). Wallets whose largest single address has < 30M can't be swept in a single transition and will sit in the persistent registry until topped up; the existing `drain_to_bank` short-circuits cleanly with a clear error in that case rather than silently leaking dust. Acceptable trade-off for the test scope. The long-term fix remains unchanged from Wave 15's note: lift `transfer::PlatformAddressWallet::estimate_fee_for_inputs` to a small public helper and call it from `cleanup.rs` so the estimate stays accurate across protocol-version bumps. Tracked as a follow-up to Marvin's QA-003. Verification (offline): - `cargo check -p platform-wallet --tests` OK - `cargo clippy -p platform-wallet --tests -- -D warnings` OK - `cargo fmt -p platform-wallet` OK No production-code (`src/`) changes; production diff vs `origin/v3.1-dev` remains exactly Wave 9's `auto_select_inputs` trim. Constant-only fix in `tests/e2e/framework/cleanup.rs`. Live retest pending Claudius. With Waves 14 (TrustedHttp), 16 (Explicit selection), and 17 (multi-input fee margin) in place both teardown_one and sweep_orphans should clear all fee gates on the typical 2-address e2e wallet.

The path is deterministic regardless of the shell's CWD; missing `.env` is silently OK (process env vars stay the source of truth); a malformed file logs a `tracing::warn!` pointing at the offending path. Operator template lives at `packages/rs-platform-wallet/tests/.env.example` — copy it to `tests/.env` and fill in `PLATFORM_WALLET_E2E_BANK_MNEMONIC`. The template documents every supported env var (network, DAPI overrides, min-credits, workdir base, trusted-context URL, RUST_LOG) with the same defaults the framework uses, commented out so the template is a working starting point. 2. **`#[ignore]` removed** from `cases::transfer::transfer_between_two_platform_addresses`. The test now runs by default once `tests/.env` is in place; `cargo test --test e2e -- --nocapture` is the canonical command. If `PLATFORM_WALLET_E2E_BANK_MNEMONIC` is unset or the bank is under-funded, the existing harness panics with the actionable bank-under-funded message (Wave 6's polish) naming the bank's primary receive address — the failure is operator-actionable, not silent. CI gating happens at the workflow level, not via `#[ignore]`. `tests/e2e/README.md` updated: - "Tests run by default" + a one-paragraph operator-error story (panic with primary receive address) replaces the old "all tests carry `#[ignore]`" wording. - Configuration section names the canonical `tests/.env` location and the `tests/.env.example` template; spells out the rs-sdk parity. `cp tests/.env.example tests/.env` snippet shows the one-time setup. - Every `cargo test … --ignored …` invocation in the README drops the `--ignored` flag (4 sites). - The canonical-pattern example test attribute drops its `#[ignore = …]` line. Stale comment block at the top of `cases/transfer.rs` that referenced Marvin's wave-5 "live happy-path run pending operator bank pre-funding" TODO is removed — the operator setup now lives in the README + `.env.example`, and the test no longer needs the breadcrumb. Verification (offline): - `cargo check -p platform-wallet --tests` OK - `cargo clippy -p platform-wallet --tests -- -D warnings` OK - `cargo fmt -p platform-wallet` OK - `cargo test -p platform-wallet --test e2e -- --list` shows `cases::transfer::transfer_between_two_platform_addresses: test` WITHOUT the `(ignored, ...)` annotation. No production-code (`src/`) changes; the diff against `origin/v3.1-dev -- src/` remains exactly Wave 9's `auto_select_inputs` trim. Wave 18 touches: - `tests/.env.example` (new) - `tests/e2e/cases/transfer.rs` (drop `#[ignore]` + stale TODO) - `tests/e2e/framework/config.rs` (rs-sdk-style `.env` loader) - `tests/e2e/README.md` (operator-facing wording) The workspace `.gitignore` already covers `.env` anywhere, so the operator's mnemonic stays uncommitted by default. After the operator moves their existing `.env` from `/home/ubuntu/platform/.env` to `/home/ubuntu/platform/packages/rs-platform-wallet/tests/.env`, `cargo test --test e2e -- --nocapture` should run end-to-end.

The previous trim path dropped the last input but left earlier inputs at full balance, allowing Σ inputs > total_output and tripping the protocol's `Σ inputs == Σ outputs` invariant.

Worked example from CodeRabbit: candidates = [(addr_a, 20M), (addr_b, 50M)] // addr_a < addr_b lex total_output = 30M fee_strategy = [DeductFromInput(0)] Old result = {addr_a: 20M, addr_b: 10M} // Σ matches; addr_a drained Drive applies DeductFromInput(0) over inputs sorted by key (BTreeMap order), hitting addr_a — whose remaining balance is 0 — so `min(fee, 0) = 0`, `fee_fully_covered = false`, validator rejects with AddressesNotEnoughFundsError. The Wave-8 single-input live e2e accidentally avoided this because the fee target had ~1B credits left over after consumption — multi-input auto-selected transfers would have hit it on first contact. This rewrite: - Phase 1 (unchanged): pick smallest DIP-17-ordered prefix covering total_output + estimated_fee. - Phase 2: identify the fee target = lex-smallest address in the prefix (= `BTreeMap` index 0, what `DeductFromInput(0)` will hit per `rs-dpp/src/address_funds/fee_strategy/.../v0/mod.rs`). - Phase 3: consume the *minimum* allowed amount from the fee target (`max(min_input_amount, total_output − Σ other balances)`) so it retains the most remaining balance for fee deduction. Error out with a descriptive AddressOperation if even that minimum leaves less than `estimated_fee` remaining. - Phase 4: distribute the rest of `total_output` across the other prefix entries in DIP-17 order. - Phase 5: defensive invariant checks. `min_input_amount` is fetched from `platform_version.dpp.state_transitions.address_funds.min_input_amount` (currently 100k across v1/v2/v3 of platform-version). For non-`[DeductFromInput(0)]` fee strategies the helper falls back to the previous "consume from front" distribution that only enforces the Σ invariant — none of the wallet's call sites use anything else today. Tests: - updated `two_input_selection_trims_only_the_last` → `two_input_selection_keeps_fee_headroom_at_index_zero` to assert the new distribution AND the headroom invariant. - updated `fee_only_tail_input_does_not_inflate_input_sum`'s expected outputs (the tail is no longer dropped — it absorbs the consumption the fee target sheds). - added `fee_target_keeps_remaining_for_fee_deduction` (CodeRabbit's exact scenario, with the headroom invariant as the load-bearing assertion). - added `fee_headroom_violation_errors` (lex-smallest address too small to retain headroom → descriptive error rather than transition the validator will reject). - `single_input_oversized_balance_trims_to_output_amount`, `insufficient_balance_errors`, `no_candidates_errors` pass unchanged. `cargo test -p platform-wallet --lib` → 117 / 117 green `cargo clippy -p platform-wallet --tests -- -D warnings` → clean `cargo fmt -p platform-wallet --check` → clean Co-Authored-By: Claude Opus 4.7 (1M context) --- .../src/wallet/platform_addresses/transfer.rs | 462 ++++++++++++++---- 1 file changed, 369 insertions(+), 93 deletions(-) diff --git a/packages/rs-platform-wallet/src/wallet/platform_addresses/transfer.rs b/packages/rs-platform-wallet/src/wallet/platform_addresses/transfer.rs index 8ba00e7e5b6..68fe664a963 100644 --- a/packages/rs-platform-wallet/src/wallet/platform_addresses/transfer.rs +++ b/packages/rs-platform-wallet/src/wallet/platform_addresses/transfer.rs @@ -288,28 +288,69 @@ fn estimate_fee_for_inputs_pub( /// /// Given a `candidates` list of `(address, balance)` pairs in /// preferred selection order (DIP-17 derivation order, in practice), -/// pick the smallest prefix that covers `total_output + estimated_fee`, -/// then trim the **last consumed input** down so that -/// `Σ inputs.credits == total_output` exactly. +/// produce an inputs map satisfying TWO invariants demanded by the +/// validator: /// -/// The fee is *not* added to the returned `Credits` values.

Reconstructs the exact `inputs` map the pre-fix `auto_select_inputs` would have returned for CodeRabbit's example (candidates (20M, 50M), total_output 30M, `DeductFromInput(0)`), runs the post-consumption remaining balances through the live dpp fee-deduction code path, and asserts `fee_fully_covered == false` — i.e. the protocol rejects it with `AddressesNotEnoughFundsError`. Distinct from `fee_target_keeps_remaining_for_fee_deduction`, which asserts the new selector's output meets the headroom invariant. This reproduction proves the bug at the protocol layer rather than merely asserting "the new output looks different" — it would have stayed red without the fix in 9ea9e7033c.

Candidates were previously collected in DIP-17 derivation index order; now they sort by balance descending before being handed to `select_inputs`. Mirrors the dash-evo-tool allocator (`src/ui/wallets/send_screen.rs:155-157`). Effects: - Single largest balance covering `total_output + estimated_fee` => 1-input result, no multi-input case, no lex-smallest fee headroom logic firing. Common path simplified. - Multi-input cases (when the largest alone isn't enough) still go through the headroom-respecting distribution introduced in 9ea9e7033c — unchanged, still correct. - No public API change. `transfer()`, `auto_select_inputs`, `select_inputs` signatures all identical. Adds `descending_order_picks_single_largest_when_sufficient` to the existing test module to lock in the common-path behavior. Other tests pass candidates directly to `select_inputs` and are order-agnostic by design — unchanged. The `fee_headroom_violation_errors` error message now includes the fee-target address, its balance, required headroom, and remaining-after-consumption to ease debugging.

[BLOCKING] Phase 4 distribution no longer produces inputs below `min_input_amount`. `auto_select_inputs` now filters candidates with `balance < min_input_amount` upfront — they cannot legally appear in the inputs map. In Phase 4, when a non-fee-target tail entry would consume less than `min_input_amount`, the residue rolls back into the fee target's consumption (which has surplus headroom by construction). Returns a descriptive error if rollback would violate the fee-target headroom invariant. 2. [BLOCKING] `transfer()` rejects unsupported `fee_strategy` shapes for `InputSelection::Auto`. Auto-select currently only implements protocol-correct logic for `[DeductFromInput(0)]`; any other strategy returns `PlatformWalletError::AddressOperation` with a clear message redirecting callers to `InputSelection::Explicit`. Explicit paths still accept arbitrary strategies (caller's responsibility). 3. [BLOCKING] When Phase 3 (`fee_target_min > fee_target_max`) fails in `select_inputs`, the algorithm now extends the prefix with the next candidate and retries instead of erroring out. Larger prefixes may yield a different lex-smallest fee target with sufficient headroom. Errors out only when candidates are exhausted and no covering prefix is feasible. 4. [SUGGESTION] `select_inputs` returns an early descriptive error when `total_output < min_input_amount` — the protocol forbids this regardless of input shape, so an explicit error beats the internal "should never trip" branch that some callers were reaching. 5. [SUGGESTION] Existing selector tests now also build a minimal `AddressFundsTransferTransitionV0` and run `validate_structure`, asserting protocol-level validity in addition to the `Σ inputs == total_output` invariant. Catches future regressions without needing a live node. Coderabbit findings DUuz (#3554), DUu1 (#3554), E5L5 (#3554), thepastaclaw findings F9fo, GMHz, GMH5, GMH_, F9fv addressed.

Output 0 absorbs the fee, so input selection skips the fee-headroom reservation. Σ inputs == Σ outputs invariant preserved via last- input trim. 5 new tests in auto_select_tests cover happy path, multi-input trim, multi- output isolation, output-too-small error, and structural validation.

A colocated drift test asserts PlatformPaymentAccountSpec::default() still matches our pinned constants — preventing silent drift if upstream defaults change. WalletAccountCreationOptions::Default is a unit variant (the (account, key_class) shape lives in the BTreeSet variant, not Default itself), so destructuring Default directly was not viable. Pinning to PlatformPaymentAccountSpec — the canonical "what does Default mean for a PlatformPayment account" struct — is the closest equivalent. Resolves PR #3549 thread r-aA6u.

Module doc points at the actual error path (`FrameworkError::Bank` for missing mnemonic, panic for under-funded bank) per Copilot's `transfer.rs:7` note. * `config.rs` — replace `derive(Debug)` with a manual impl that redacts `bank_mnemonic` so a stray `{config:?}` log or panic backtrace can't leak the shared funding seed (CodeRabbit `config.rs:50`). * `workdir.rs` — match `ErrorKind::WouldBlock` as slot-busy and propagate every other IO error as `FrameworkError::Io`, instead of swallowing them all as "slot busy" (CodeRabbit `workdir.rs:50`). * `registry.rs` — drop the never-set `EntryStatus::Sweeping` variant + doc references; the per-slot workdir lock already serialises the only writer, so no transient cross-process state is required (Copilot `registry.rs:35`, `cleanup.rs:75`). * `cleanup.rs` — replace the hardcoded `SWEEP_DUST_THRESHOLD` constant with the protocol's `min_input_amount` from `PlatformVersion`, so the sweep gate stays in lock-step with whatever `address_funds` validation requires. * `wait_hub.rs` — fix stale `platform_address_sync` import path; the module moved to `manager::platform_address_sync` in PR #3564 and is re-exported at the crate root. * `README.md` — fenced-code-block language tags (MD040), corrected workdir-exhausted error string, first-run timing reflects `TrustedHttpContextProvider` default (no SPV in critical path), troubleshooting note rescoped, teardown step list no longer claims to wait for the bank to observe credits.

Once PR #3533 (`feat(sdk): source mainnet/testnet bootstrap from dash-network-seeds`) lands in `v3.1-dev` and exposes `SdkBuilder::new_testnet()` properly (currently `unimplemented!()` on this branch's base), the helper collapses into a single `SdkBuilder::new_testnet()` call with no behavioural delta. `framework/spv.rs::seed_p2p_peers` follows suit: testnet peer IPs come from `dash_network_seeds::evo_seeds(Testnet)` when the operator hasn't supplied an explicit DAPI list. Also drops the dead `TESTNET_DAPI_ADDRESSES` re-import. Adds `dash-network-seeds` as a dev-dependency, pinned to the same rust-dashcore rev as the workspace `dashcore` to keep all sibling crates in lock-step. Resolves the `sdk.rs:41` review thread.

Drops the harness's local `default_address_list_for_network` helper (which had been the byte-for-byte mirror placeholder) and delegates to the upstream builders directly. Network-explicit operator overrides via `PLATFORM_WALLET_E2E_DAPI_ADDRESSES` still route through `SdkBuilder::new(...)`. Switches `dash-network-seeds` from a git-rev-pinned dev-dep to `workspace = true` — PR #3570 added the workspace entry; the dep now only serves `framework/spv.rs::seed_p2p_peers`, which the SPV runtime needs in raw `SocketAddr` form (no `SdkBuilder`-equivalent helper exists for that).

IPs come from each `Address::uri().host()`; non-IP hosts (DNS targets) are left for the SPV client's discovery loop. * `start_spv` takes the address list as a new parameter; the commented-out caller in `harness.rs` updated to pass `sdk.address_list()`. * Drops `dash-network-seeds` from `[dev-dependencies]` — the workspace entry stays for other consumers, but the platform-wallet test harness no longer needs it.

Callers don't have to re-derive defaults at use time; the read-then-derive helpers (`parse_network`, `effective_p2p_port`) are gone. Concretely: * `Config::network: String` -> `Network`. Parsed at construction via the now-private `parse_network` helper, which still accepts the `local` alias and the empty-string testnet shorthand. * `Config::p2p_port: Option` semantics preserved (`None` only for regtest / devnet without an override) but the value is the resolved override-or-default — no further lookup required. Resolution happens in `Config::from_env` and `Default::default` via the now- private `default_p2p_port` helper. * `parse_network` and `default_p2p_port` are demoted from `pub(super)` to private — they're construction-time implementation details, not part of the cross-module API. * `effective_p2p_port` deleted entirely (callers read `config.p2p_port` directly). * `bank.rs`, `sdk.rs`, `spv.rs` updated to consume the resolved `config.network` / `config.p2p_port` instead of re-parsing. `seed_p2p_peers` drops the explicit `Network` argument since the resolved port already encodes whatever network-default came from config construction. No behaviour delta — just moves the resolution from "every call site" to "one place at boot."

Right then. +This document enumerates the work to do; another document, somewhere, will +presumably enumerate the joy of doing it. + +--- + +## 1. Overview + +The `rs-platform-wallet` end-to-end suite lives at +`packages/rs-platform-wallet/tests/e2e/` and executes against Dash testnet via +the SDK and a pre-funded "bank" platform-address wallet. The harness was +introduced in PR #3549 (branch `feat/rs-platform-wallet-e2e`) and ships with a +single live case — `transfer_between_two_platform_addresses` — exercising +platform-address credit transfer between two addresses owned by the same test +wallet. + +This specification proposes a layered set of cases, grouped by feature area, +prioritised P0/P1/P2, and annotated with the harness extensions each requires. +Every case targets the production `PlatformWallet` API surface (no test-only +shims into the wallet), uses the bank-funded credit model already wired in +`framework/bank.rs`, and assumes the same network model PR #3549 ships with: +testnet by default, devnet/local by env override, no Layer-1 / Core-UTXO +assumptions for any P0/P1 case (Task #15 — SPV — is the gating dependency for +Core-feature tests). + +The spec is implementation-agnostic. Authors should consume it, not migrate it +verbatim from `dash-evo-tool` (DET) — DET parallels are cited only to anchor +intent and to surface battle-tested edge cases. The harness lives on top of +`PlatformWalletManager` and a `TrustedHttpContextProvider`, +so anything requiring SPV proofs, asset locks, shielded notes, or fresh contract +deployment is explicitly deferred (see §5). + +### 1.1 Priority scheme + +Every test case carries one of three priority levels. The priority drives both +listing order within a section and CI gating tier. + +- **P0 — Primary path.** The happy path that demonstrates the feature works. + CI-gating tier; failure blocks merge. Execute first. +- **P1 — Core variants.** Negative paths and alternate-input variants of P0 + cases that protect the primary contract. Execute alongside P0 in CI. +- **P2 — Edge cases.** Boundary, empty-input, concurrency, malformed-input, + and discovered-gap cases. Run nightly / on-demand; not gating unless an + active regression makes one of them so. Execute after P0/P1. + +Within each feature-area subsection (Platform Addresses, Identity, Tokens, +DPNS, Dashpay, etc.), test cases are listed P0 first, then P1, then P2. The +suffix-letter convention (e.g. `PA-001b`, `PA-002c`) groups variant cases next +to their parent; new top-level edge cases get fresh dense IDs (e.g. `PA-009`, +`PA-010`). No existing case ID is renumbered; new cases slot in adjacent to +their parent. + +### 1.2 Mnemonic / seed source + +Mnemonics used by the harness (bank wallet, every `TestWallet`) MUST be drawn +from the BIP-39 English wordlist. Out-of-band entropy paths — raw entropy, +non-BIP-39 wordlists, or arbitrary UTF-8 strings fed as "mnemonic" — are out +of scope for this suite. Any test that generates a seed does so via the +BIP-39 mnemonic generator already used by `framework/wallet_factory.rs`. Cases +that exercise non-ASCII content (e.g. Unicode display names) do so on +downstream fields, not on the seed. + +--- + +## 2.

Bank-fund the address; wait for balance. + 3. Call `next_unused_address()` once more. Must return a different address. + 4. Repeat steps 2-3 fifteen times (total 16 distinct addresses), funding each. + 5. After 16 used addresses, derive the 17th via `next_unused_address()` — still inside gap window. +- **Assertions**: + - First three calls return the same `PlatformAddress` (cursor not advanced). + - Each post-funding call advances the cursor: 16 distinct addresses observed. + - The 17th address is derivable (within `DEFAULT_GAP_LIMIT`). + - `signer.cached_key_count() >= 17`. +- **Negative variants**: + - Derive 21+ unused addresses without funding — expect either gap-limit growth or a typed "gap exceeded" error (whichever the wallet contract defines; this case will surface that contract). +- **Harness extensions required**: `signer.cached_key_count()` is already public (`signer.rs:144`); no other harness change. +- **Estimated complexity**: M (bookkeeping ≈ 200 LoC; 16 funding round-trips means a long-running test — gate it under a slow-tests feature or accept ~3 min runtime). +- **Rationale**: The fix in commit `60f7850ab0` ("sort auto-select candidates by balance descending") is one of several invariants in the address provider that needs a regression test. PA-005 also documents the "cursor advances on observed-used" property that bit Wave 8 in PR #3549 (see `cases/transfer.rs:91-97`). + +#### PA-006 — Replay safety: same outputs, second submission rejected +- **Priority**: P1 +- **Wallet feature exercised**: nonce handling inside `PutPlatformAddresses::put_with_address_funding_fetching_nonces` (re-broadcast). +- **DET parallel**: `dash-evo-tool/tests/backend-e2e/wallet_tasks.rs:234` indirectly tests nonces. +- **Preconditions**: bank-funded test wallet. +- **Scenario**: + 1. Fund `addr_1` with `50_000_000`. + 2. Capture the underlying state-transition bytes (requires exposing the changeset's `serialized_transition` — see harness extension below). + 3. Transfer `10_000_000` to `addr_2` (succeeds). + 4. Submit the captured bytes a second time via `sdk.broadcast_state_transition` directly. +- **Assertions**: + - Second submission returns a "stale nonce" / "already exists" SDK error (assert error class). + - Wallet's view of `addr_1` and `addr_2` is unchanged after the failed re-submit. +- **Negative variants**: none — this case IS the negative variant of PA-001. +- **Harness extensions required**: a `TestWallet::transfer_capturing_st_bytes` helper that returns the encoded ST alongside the change-set. ~30 LoC, plumbs through the SDK's `put_*` builder rather than `transfer()`. +- **Estimated complexity**: M (single-file, harness touch) +- **Rationale**: Closes a quiet but high-blast-radius regression class — nonce handling. If the SDK ever stops bumping nonces correctly, every wallet's "spam-click" UX breaks. PA-006 surfaces it deterministically. + +#### PA-007 — Sync watermark idempotency +- **Priority**: P1 +- **Wallet feature exercised**: `wallet/platform_addresses/sync.rs:24` (`sync_balances`); `wallet/platform_addresses/wallet.rs:153` (`restore_sync_state`). +- **DET parallel**: implicit in DET's wallet-task lifecycle. +- **Preconditions**: bank-funded test wallet. +- **Scenario**: + 1. Bank-fund `addr_1` with `30_000_000`; wait. + 2. Call `sync_balances` three times in a row. + 3. Capture the post-sync watermark via `wallet.platform()..last_known_recent_block` (read through public state guard). +- **Assertions**: + - All three syncs succeed. + - Watermark is monotonic non-decreasing across calls. + - Cached balances are byte-equal across calls (no spurious mutation on re-sync). +- **Negative variants**: + - Disconnect from DAPI (config override to a bogus URL) and call `sync_balances` → typed network error; cached balances unchanged. +- **Harness extensions required**: an accessor on `TestWallet` to read the platform-address provider's sync state (or expose it through the existing `platform_wallet()` borrow + a public watermark getter on the provider — already on the API, just needs threading). +- **Estimated complexity**: M +- **Rationale**: Re-sync idempotency is silently load-bearing — UI clients call `sync_balances` on every refresh tick. A regression that double-counts on re-sync would be visually obvious in apps and silent in unit tests; PA-007 makes it explicit. + +#### PA-008 — Concurrent funding from bank: serialised by FUNDING_MUTEX +- **Priority**: P1 +- **Wallet feature exercised**: `framework/bank.rs::fund_address` and its `FUNDING_MUTEX` invariant. +- **DET parallel**: none — DET's bank model differs. +- **Preconditions**: bank-funded test wallet. +- **Scenario**: + 1. Derive `addr_1`, `addr_2`, `addr_3`. + 2. Spawn three concurrent `bank.fund_address` tasks (each `10_000_000`). + 3. Await all three. + 4. Sync. +- **Assertions**: + - All three addresses end with the funded amount (no nonce collisions, no lost funding). + - Total bank decrease == `30_000_000 + 3 * fund_fee`. + - No panic in `FUNDING_MUTEX` path. +- **Negative variants**: none — this case validates concurrency safety as a property. +- **Harness extensions required**: none. +- **Estimated complexity**: S +- **Rationale**: Encodes the FUNDING_MUTEX guarantee documented in `framework/bank.rs:39`. Without it, a future refactor that drops the mutex (or misuses it) would corrupt nonces and only surface intermittently. + +#### PA-002b — Zero-change exact-equality (`Σ outputs + fee == input balance`) +- **Priority**: P1 +- **Wallet feature exercised**: `wallet/platform_addresses/transfer.rs:31`; change-output suppression at the `Σ inputs == Σ outputs` boundary recently fixed in `aaf8be74ee` and `9ea9e7033c`. +- **DET parallel**: none — this is a regression-pinning case for our own commits. +- **Preconditions**: bank-funded test wallet. +- **Scenario**: + 1. Bank-fund `addr_1` with `60_000_000` and let it settle. Record `bal_1 = addr_1` balance. + 2. Build a one-output transfer `{addr_2: bal_1 - estimated_fee}` where `estimated_fee` is derived from the wallet's fee preview (or a calibrated PA-003 measurement). + 3. Tighten the output by 1 credit at a time until `Σ outputs + actual_fee == bal_1` exactly. Submit. +- **Assertions**: + - Transfer succeeds (no spurious "below dust" or change-output validation error). + - The on-wire state-transition contains exactly **one** output (the destination); no change output is materialised. + - `addr_1` post-balance == `0` exactly. Not `1`, not `dust_threshold`, not `None`. + - `balances[addr_2] == bal_1 - actual_fee` exactly. +- **Negative variants**: none (this case IS the boundary). +- **Harness extensions required**: a `TestWallet::estimate_transfer_fee(&outputs)` helper, or fall back to PA-003's empirical fee constants. +- **Estimated complexity**: S +- **Rationale**: Pins the `Σ inputs == Σ outputs + fee` invariant the wallet just shipped regressions on. Without an exact-equality boundary case, that bug-class re-emerges silently the next time the change-output predicate is touched. + +#### PA-010 — Bank starvation: typed `BankUnderfunded` error +- **Priority**: P1 +- **Wallet feature exercised**: `framework/bank.rs::fund_address` precondition checks. +- **DET parallel**: none — operator-actionable harness contract. +- **Preconditions**: bank deliberately underfunded for the test (e.g. configure a fresh test bank with `5_000_000` total credits). +- **Scenario**: + 1. Configure the harness so `bank.total_credits()` is below the test's requested fund amount. + 2. Call `bank.fund_address(addr_1, 30_000_000)`. +- **Assertions**: + - `bank.fund_address` returns a typed `BankError::Underfunded { available, requested }` (or the equivalent named variant — pin whatever the code calls it). No panic, no generic `anyhow!` shape. + - Error message names the bank wallet id, the available balance, and the requested amount, so an operator can act without code-diving. + - The bank's funding mutex is released cleanly (a follow-up successful call after re-funding the bank works). + - Test wallet registry contains no half-created entry from the failed fund. +- **Negative variants**: none. +- **Harness extensions required**: a typed error variant on `framework/bank.rs` (most likely already present; confirm name); a way to construct an underfunded bank for the test (a `Bank::with_balance_for_test(...)` constructor or a fresh bank wallet pre-drained). +- **Estimated complexity**: S +- **Rationale**: Bank starvation is the single most common "weird CI failure" mode for this suite, and the failure mode shouldn't be a panic from inside `fund_address`. PA-010 makes the operator-actionable error part of the contract. + +#### PA-001b — Transfer with `output_change_address: None` vs `Some(addr)` +- **Priority**: P2 +- **Wallet feature exercised**: `wallet/platform_addresses/transfer.rs:31`; the `output_change_address: Option` argument routes change either to an auto-derived address or to an explicit one. +- **DET parallel**: none — exercises an Option-branch the existing PA cases never split. +- **Preconditions**: bank-funded test wallet. +- **Scenario**: + 1. Bank-fund `addr_1` with `60_000_000`. + 2. Run transfer `{addr_2: 5_000_000}` with `output_change_address: None`. Record the address that ended up holding the change. + 3. Bank-fund a fresh `addr_3` with `60_000_000`. + 4. Derive an explicit `change_addr` separately from `addr_3` (and from any output address). + 5. Run transfer `{addr_4: 5_000_000}` from `addr_3` with `output_change_address: Some(change_addr)`. +- **Assertions**: + - `None` branch: change lands on the wallet-internal documented "auto-derive change" address (likely the next unused receive address); record exactly which one and pin the rule in the assertion. + - `Some(change_addr)` branch: change balance shows up on `change_addr` exactly, and not on the source or any other address. + - In both branches `Σ inputs == Σ outputs + fee` holds. +- **Negative variants**: + - `output_change_address: Some(addr_with_existing_balance)` → assert merge-or-reject contract (whichever the wallet defines). +- **Harness extensions required**: none. +- **Estimated complexity**: S +- **Rationale**: The `Option` argument has no asserted contract today — `None` could drift into "change is silently lost" without a single test failing. + +#### PA-001c — Zero-credit single-output transfer +- **Priority**: P2 +- **Wallet feature exercised**: `wallet/platform_addresses/transfer.rs:31` boundary at output-amount zero. +- **DET parallel**: none. +- **Preconditions**: bank-funded test wallet. +- **Scenario**: + 1. Bank-fund `addr_1` with `30_000_000`. + 2. Call `transfer({addr_2: 0})` from `addr_1`. +- **Assertions**: pin one of the two contracts (whichever the wallet implements): + - **(a) Reject**: a typed validation error of "amount must be positive" shape; no state-transition broadcast; balances unchanged. + - **(b) Accept as fee-only**: transfer broadcasts; `balances[addr_2] == 0`; `addr_1` decreased by `fee` only. +- **Negative variants**: none — this case IS the zero-amount boundary. +- **Harness extensions required**: none. +- **Estimated complexity**: S +- **Rationale**: Zero-amount transfers are a classic boundary. The wallet's contract here is currently undocumented; whichever it is, an explicit case pins it. + +#### PA-004b — Sweep dust threshold boundary triplet +- **Priority**: P2 +- **Wallet feature exercised**: `framework/cleanup.rs` sweep gate at `SWEEP_DUST_THRESHOLD` (5_000_000 credits). +- **DET parallel**: none. +- **Preconditions**: bank-funded test wallet × 3 (one per boundary). +- **Scenario**: run three sub-cases independently, with wallet balance configured exactly: + 1. Balance == `SWEEP_DUST_THRESHOLD - 1` (i.e. `4_999_999`). Call cleanup. Assert sweep is **skipped** (registry status `Skipped`, no broadcast). + 2. Balance == `SWEEP_DUST_THRESHOLD` (i.e. `5_000_000`). Call cleanup. Assert sweep is **attempted** (broadcast emitted, bank credit observed minus fees). + 3. Balance == `SWEEP_DUST_THRESHOLD + 1` (i.e. `5_000_001`). Call cleanup. Assert sweep is **attempted**. +- **Assertions**: each sub-case asserts the registry status string and whether a state-transition was broadcast. The boundary at `==` must distinguish from `< threshold`. +- **Negative variants**: none. +- **Harness extensions required**: a way to configure a test wallet to hold an exact balance after fund + fee accounting (likely fund a slightly larger amount, then transfer the excess to a sink). May require the `TestWallet::transfer_with_inputs` helper (Wave F). +- **Estimated complexity**: M +- **Rationale**: The dust threshold is one of the few hard numeric gates in the cleanup path. Off-by-one at this boundary is the canonical bug class. + +#### PA-004c — Sweep with exactly zero balance +- **Priority**: P2 +- **Wallet feature exercised**: `framework/cleanup.rs` sweep path with empty inputs. +- **DET parallel**: none. +- **Preconditions**: bank-funded harness; test wallet seeded but never funded (or fully drained before cleanup). +- **Scenario**: + 1. Create a fresh `TestWallet`. Do not fund it. + 2. Call `setup_guard.teardown()`. +- **Assertions**: + - Cleanup returns `Ok(())`. + - Registry status for the wallet is `Skipped` (no broadcast attempted). + - No DAPI broadcast call is made (assert via a counter on the test SDK harness, or by absence of nonce consumption on the bank). +- **Negative variants**: none. +- **Harness extensions required**: a "did we broadcast?" hook on the harness SDK, or a registry status accessor. +- **Estimated complexity**: S +- **Rationale**: A no-op cleanup must not throw. Without this case a refactor that moves the empty-input check could regress to `Err(InsufficientFunds)` and the test suite would never notice. + +#### PA-005b — `DEFAULT_GAP_LIMIT` triplet (19 / 20 / 21 unused) +- **Priority**: P2 +- **Wallet feature exercised**: `wallet/platform_addresses/wallet.rs:180` gap-limit enforcement at `DEFAULT_GAP_LIMIT = 20`. +- **DET parallel**: none direct; PA-005 covers cursor rotation but not the gap-limit boundary. +- **Preconditions**: bank-funded test wallet. +- **Scenario**: three sub-cases run on separate `TestWallet` instances: + 1. Derive **19** unused addresses (no funding). Then derive a 20th. Assert all 20 are returned without error or gap-limit growth event. + 2. Derive **20** unused addresses (no funding). Then derive a 21st. Pin the contract: either the wallet returns a typed `GapLimitExceeded` error, or it grows the limit (assert a `GapLimitGrown` event, or whatever the wallet exposes). + 3. Derive **21** unused addresses by request, asserting the same contract as (2). +- **Assertions**: each sub-case nails the wallet's contract at the `DEFAULT_GAP_LIMIT` boundary. +- **Negative variants**: none — this case is the boundary. +- **Harness extensions required**: a way to derive without funding (already supported via `next_unused_address` repeatedly; confirm cursor doesn't auto-park). +- **Estimated complexity**: M +- **Rationale**: PA-005's "21+ unused addresses" line is exploratory; PA-005b promotes it to an asserted boundary on each side of `DEFAULT_GAP_LIMIT`. + +#### PA-006b — Two concurrent broadcasts of identical ST bytes +- **Priority**: P2 +- **Wallet feature exercised**: nonce / replay-protection at the SDK / DAPI boundary. +- **DET parallel**: none. +- **Preconditions**: bank-funded test wallet; PA-006's `transfer_capturing_st_bytes` helper. +- **Scenario**: + 1. Fund `addr_1` and capture the encoded ST bytes for a transfer (do not broadcast yet). + 2. Spawn two concurrent `tokio::spawn` tasks each calling `sdk.broadcast_state_transition(captured_bytes)`. + 3. Await both. +- **Assertions**: + - Exactly one of the two futures returns success; the other returns the documented stale-nonce / already-exists / duplicate-broadcast error class. + - Final wallet state matches a single applied transfer (no double-debit). +- **Negative variants**: none. +- **Harness extensions required**: PA-006's `transfer_capturing_st_bytes`. +- **Estimated complexity**: M +- **Rationale**: PA-006 covers sequential replay; the race-condition variant is materially different code path inside the SDK / DAPI mempool. + +#### PA-007b — Two concurrent `sync_balances` on one wallet +- **Priority**: P2 +- **Wallet feature exercised**: `wallet/platform_addresses/sync.rs:24` reentrancy / internal locking. +- **DET parallel**: none. +- **Preconditions**: bank-funded test wallet. +- **Scenario**: + 1. Fund `addr_1` with `30_000_000`; wait for visibility. + 2. Spawn two concurrent `sync_balances()` futures on the same `TestWallet` handle. + 3. Await both. +- **Assertions**: + - Both futures return `Ok(())`. + - Post-state cached balance equals on-chain truth (not 2× — no double-counting). + - Sync watermark advanced exactly once net (no spurious double-bump). +- **Negative variants**: none. +- **Harness extensions required**: same accessor PA-007 already requires. +- **Estimated complexity**: M +- **Rationale**: PA-007 is sequential; double-counting under concurrent re-sync is a UI-tier hazard worth pinning. + +#### PA-008b — Two `TestWallet`s × three concurrent funders each +- **Priority**: P2 +- **Wallet feature exercised**: `framework/bank.rs::fund_address` cross-wallet contention. +- **DET parallel**: none. +- **Preconditions**: bank with `≥ 70_000_000 + 6 * fund_fee` credits. +- **Scenario**: + 1. Spin up two independent `TestWallet` instances, A and B. + 2. Derive `a1, a2, a3` on A and `b1, b2, b3` on B. + 3. Spawn six concurrent `bank.fund_address` calls (three on A's addresses, three on B's, each `10_000_000`). + 4. Await all six. +- **Assertions**: + - All six addresses end with the funded amount (no nonce collision across wallet boundaries). + - Total bank decrease == `60_000_000 + 6 * fund_fee`. + - No panic, no missing balances on any sub-set after sync. +- **Negative variants**: none. +- **Harness extensions required**: helper to instantiate two independent `TestWallet`s in one harness setup. +- **Estimated complexity**: M +- **Rationale**: PA-008 keeps contention inside one `TestWallet`; PA-008b proves the bank's serialisation works under cross-wallet contention too — the realistic CI shape. + +#### PA-008c — Observable serialisation of `FUNDING_MUTEX` +- **Priority**: P2 +- **Wallet feature exercised**: `framework/bank.rs::FUNDING_MUTEX` invariant. +- **DET parallel**: none. +- **Preconditions**: bank-funded test wallet; instrumentation hook on `FUNDING_MUTEX` (entry/exit timestamps or per-call sequence number). +- **Scenario**: + 1. Spawn three concurrent `bank.fund_address` tasks. + 2. Each task records its mutex-entry timestamp and mutex-exit timestamp via a test-only instrumentation hook. + 3. Await all three. +- **Assertions**: + - The three intervals `[entry_i, exit_i]` are pairwise non-overlapping (proves serialisation, not just correctness). + - Equivalently / additionally: the bank's funding-tx nonces are strictly monotonic in the same order as the mutex entries. +- **Negative variants**: none. +- **Harness extensions required**: an instrumentation hook on `framework/bank.rs` (test-only `cfg(test)` accessor for the mutex's last-entry sequence, or a `parking_lot::Mutex` instrumentation wrapper). +- **Estimated complexity**: M +- **Rationale**: PA-008 tests "all three calls succeed" — a future refactor that drops the mutex but happens to win the race in CI would still pass. PA-008c asserts the *mechanism* observably, so a silent removal of the mutex fails the test deterministically. + +#### PA-009 — `min_input_amount` boundary triplet for cleanup +- **Priority**: P2 +- **Wallet feature exercised**: `framework/cleanup.rs::min_input_amount`, sourced from `platform_version.dpp.state_transitions.address_funds.min_input_amount`. +- **DET parallel**: none. +- **Preconditions**: bank-funded harness; test wallet × 3, each with a precisely tuned balance. +- **Scenario**: read `min` = `platform_version.dpp.state_transitions.address_funds.min_input_amount`. Run three sub-cases: + 1. Balance == `min - 1`. Call cleanup. Assert `Skipped` (cleanup must not attempt sweep). + 2. Balance == `min`. Call cleanup. Assert sweep is attempted (broadcast emitted; or fails with the documented "fee pushes below threshold" typed error). + 3. Balance == `min + 1`. Call cleanup. Assert sweep is attempted and succeeds. +- **Assertions**: each sub-case pins the cleanup status (`Skipped` vs attempted) and the typed error if the attempt fails. +- **Negative variants**: none. +- **Harness extensions required**: PA-004b's exact-balance setup helper; a way to read `min_input_amount` from the active `PlatformVersion` inside the test. +- **Estimated complexity**: M +- **Rationale**: `min_input_amount` is currently entirely uncovered. A protocol-version bump that changes the value would silently shift cleanup behaviour, with no failing test to flag the shift. + +#### PA-011 — Workdir slot exhaustion at `MAX_SLOTS + 1` +- **Priority**: P2 +- **Wallet feature exercised**: `framework/workdir.rs` `flock`-based slot allocation; `MAX_SLOTS = 10`. +- **DET parallel**: none — operator-actionable harness contract. +- **Preconditions**: a clean workdir base path with no held slots. +- **Scenario**: + 1. Spawn `MAX_SLOTS` sub-processes (or `MAX_SLOTS` concurrent harness contexts within one process) that each acquire and hold a workdir slot. + 2. Spawn one additional (i.e. the 11th) harness context attempting to acquire a slot. +- **Assertions**: + - The first `MAX_SLOTS` acquisitions succeed and land on distinct slot indices. + - The 11th returns a typed `WorkdirError::NoAvailableSlots { tried, base_path }` (pin the variant name) within a bounded time — no silent infinite wait. + - Cleanup releases all slots; a subsequent acquisition succeeds. +- **Negative variants**: none. +- **Harness extensions required**: a typed error variant on `framework/workdir.rs` (likely already there; confirm name); a way to spawn sub-processes for the test, or simulate slot holders within one process via held `flock` guards. +- **Estimated complexity**: M +- **Rationale**: Slot exhaustion is the second most common "weird CI failure" mode after bank starvation. PA-011 makes its failure mode explicit. + +#### PA-012 — `sync_balances` racing with `transfer` +- **Priority**: P2 +- **Wallet feature exercised**: internal locking between `wallet/platform_addresses/sync.rs:24` and `wallet/platform_addresses/transfer.rs:31`. +- **DET parallel**: none. +- **Preconditions**: bank-funded test wallet. +- **Scenario**: + 1. Bank-fund `addr_1` with `40_000_000`; wait. + 2. Spawn two concurrent tasks: `wallet.sync_balances()` and `wallet.transfer({addr_2: 5_000_000})`. + 3. Await both. +- **Assertions**: + - Both return `Ok(...)`. + - Final state is consistent with sequential execution: `balances[addr_2] == 5_000_000`, `balances[addr_1] == 40_000_000 - 5_000_000 - fee`. No "fee charged twice", no "in-flight transfer double-counted". + - The transfer's fee was computed against a non-stale balance view (i.e. no `InsufficientFunds` because `sync_balances` clobbered the cache mid-build). +- **Negative variants**: none. +- **Harness extensions required**: none beyond what PA-002 / PA-007 already need. +- **Estimated complexity**: M +- **Rationale**: Mobile clients call `sync_balances` aggressively while the user is typing into a transfer form. A regression where these two paths race silently produces wrong fees or stale balances; PA-012 pins the contract. + +#### PA-013 — Broadcast retry under transient DAPI 5xx +- **Priority**: P2 +- **Wallet feature exercised**: SDK retry policy on `broadcast_state_transition` under transient HTTP 5xx; downstream wallet state-finalisation on partial success. +- **DET parallel**: none direct; PA-007's negative variant covers a permanently-bogus URL only. +- **Preconditions**: a test-only DAPI proxy (or a `httpmock`-based DAPI stub) that returns `503 Service Unavailable` on the first call to `/broadcastStateTransition` and succeeds thereafter. +- **Scenario**: + 1. Bank-fund `addr_1`. + 2. Configure the harness SDK to point at the proxy. + 3. Issue a transfer. +- **Assertions**: + - Wallet returns `Ok(...)` despite the transient 5xx (assuming policy is to retry; if the policy is "fail fast and surface to caller", invert the assertion and document that contract). + - Final on-chain state shows the transfer applied exactly once (proxy's request log shows two POSTs — one 503, one 200; chain shows one ST). + - On the proof-fetch failure variant (DAPI succeeds on broadcast, 5xx on proof fetch): wallet either retries proof fetch, or returns a `BroadcastedAwaitingProof` typed result (whichever the contract defines). +- **Negative variants**: + - DAPI returns 5xx persistently → typed `NetworkError` after exhausted retries; cached wallet state unchanged. +- **Harness extensions required**: a controllable test DAPI proxy (Wave F-adjacent). This is non-trivial; mark as "blocked on test-DAPI-proxy infra" if unavailable. +- **Estimated complexity**: M +- **Rationale**: Transient 5xx is the most common production failure mode for thin-client SDKs. Without a deterministic test, retry policy drifts between "broken" and "infinite loop" and nobody notices until users complain. + +#### PA-014 — Multi-output at protocol-max output count +- **Priority**: P2 +- **Wallet feature exercised**: `wallet/platform_addresses/transfer.rs:31` at the protocol max-output boundary; payload-size limits in DPP / Drive. +- **DET parallel**: none. +- **Preconditions**: bank-funded test wallet with sufficient credits to fund N outputs (where N is the protocol max for `address_funds` outputs). +- **Scenario**: + 1. Discover the protocol-max output count from `platform_version.dpp.state_transitions.address_funds.max_outputs` (or the equivalent constant). + 2. Bank-fund `addr_1` with enough credits to cover N outputs of `100_000` each plus fees. + 3. Construct a transfer with exactly `max_outputs` destinations; submit. Record the result. + 4. Construct a transfer with `max_outputs + 1` destinations; submit. +- **Assertions**: + - At `max_outputs`: transfer succeeds; all N destinations reach the expected balance. + - At `max_outputs + 1`: wallet returns a typed `PayloadTooLarge` / `TooManyOutputs` validation error before broadcast (or, if the wallet attempts and DAPI rejects, the SDK error class is mapped to a typed wallet error). Pin which side enforces. +- **Negative variants**: none. +- **Harness extensions required**: ability to read `max_outputs` from the active platform version; a pool of `max_outputs + 1` distinct destination addresses (likely already available via `next_unused_address` on a fresh wallet). +- **Estimated complexity**: M +- **Rationale**: The wallet's only multi-output coverage today is "5 outputs". The actual upper limit is unmeasured; a protocol-version bump that changes `max_outputs` would silently shift behaviour, with regressions surfacing only in production state-transitions that are mysteriously rejected. + +### Identity (ID) + +#### ID-001 — Register identity funded from platform addresses +- **Priority**: P0 +- **Wallet feature exercised**: `wallet/identity/network/register_from_addresses.rs:65` (`IdentityWallet::register_from_addresses`). +- **DET parallel**: `dash-evo-tool/tests/backend-e2e/identity_create.rs:13` (`test_create_identity`) — DET uses asset-lock; we use the address-funded variant explicitly. +- **Preconditions**: bank-funded test wallet; identity-signer harness extension landed. +- **Scenario**: + 1. Derive `addr_1`, bank-fund with `60_000_000`, wait for balance. + 2. Build a placeholder `Identity` with one `MASTER` ECDSA key and one `HIGH` ECDSA key derived via DIP-9 (identity index `0`). + 3. Call `IdentityWallet::register_from_addresses(identity, {addr_1: 50_000_000}, output: None, identity_index: 0, identity_signer, address_signer, settings: None)`. + 4. Wait for the identity to appear on-chain by `sdk.fetch::(identity.id())`. +- **Assertions**: + - Returned `Identity::id()` is non-zero and equals the on-chain fetched identity. + - On-chain identity public-keys count == 2. + - Identity balance == `50_000_000 - identity_create_fee` (`identity_create_fee > 0`). + - `addr_1` residual balance == `60_000_000 - 50_000_000 - tx_fee`. + - `IdentityManager::known_identities()` lists exactly this identity. +- **Negative variants**: + - `inputs` is empty → wallet returns `PlatformWalletError::InvalidIdentityData("At least one input address is required")` (already enforced at `register_from_addresses.rs:78`; assert exact message stability). + - Insufficient funds in input → SDK error class. + - Placeholder `Identity` with zero keys → identity-create transition rejection. +- **Harness extensions required**: + - `Signer` impl — Wave A (see §4). + - `TestWallet::register_identity_from_addresses(funding: Credits) -> Identity` helper that wraps the placeholder build + call. + - `wait_for_identity_balance(identity_id, expected, timeout)` helper. +- **Estimated complexity**: L (multi-file harness extension) +- **Rationale**: Highest-leverage Identity test. The address-funded path is currently exercised by no test anywhere in the workspace — FFI binds the asset-lock variant only.

Register `identity_a` and `identity_b` (sequential ID-001 invocations on different addresses). + 2. Capture pre-balances. + 3. Transfer `10_000_000` credits from `identity_a` to `identity_b`. +- **Assertions**: + - `post_a == pre_a - 10_000_000 - transfer_fee`, `transfer_fee > 0` + - `post_b == pre_b + 10_000_000` + - `IdentityManager` reflects both new balances after sync. +- **Negative variants**: + - Transfer amount exceeds sender balance → typed error. + - Transfer to self (`identity_a -> identity_a`) → typed error. +- **Harness extensions required**: Wave A only (everything inherits ID-001). +- **Estimated complexity**: M +- **Rationale**: Confirms identity-balance bookkeeping in `ManagedIdentity` is bidirectional and idempotent. Pairs with ID-002 to cover the symmetric "credit increase" + "credit decrease" code paths. + +#### ID-004 — Identity update: add and disable a key +- **Priority**: P1 +- **Wallet feature exercised**: `wallet/identity/network/update.rs:89` (`update_identity_with_external_signer`). +- **DET parallel**: `dash-evo-tool/tests/backend-e2e/identity_tasks.rs:188` (`step_add_key`) and `tc_020_identity_mutation_lifecycle`. +- **Preconditions**: ID-001 helper. +- **Scenario**: + 1. Register identity with MASTER + HIGH keys (purpose AUTHENTICATION). + 2. Build a new HIGH ECDSA key (purpose AUTHENTICATION) — derive via identity-key derivation Wave A helper. + 3. Issue an `IdentityUpdateTransition` adding the new key. + 4. Issue a second update disabling the original HIGH key. + 5. Refresh identity from chain. +- **Assertions**: + - After step 3: identity has 3 keys, the new key is `is_disabled == false`. + - After step 4: original HIGH key has `disabled_at != None`; new HIGH key still active. + - MASTER key is untouched. +- **Negative variants**: + - Disable last MASTER key → typed error (CRITICAL/MASTER class invariant). + - Add key signed by non-MASTER → typed error. +- **Harness extensions required**: Wave A; plus a `derive_identity_key(identity_index, key_index, purpose, security_level)` test helper. +- **Estimated complexity**: L +- **Rationale**: Identity-update pathways have multiple silent failure modes (key-class restrictions, MASTER signing requirements). Recent commit `844eef74e8` ("token transitions require a CRITICAL signing key") shows this surface is actively changing — coverage prevents future regressions. + +#### ID-005 — Transfer credits from identity to platform addresses +- **Priority**: P1 +- **Wallet feature exercised**: `wallet/identity/network/transfer_to_addresses.rs:66`. +- **DET parallel**: `dash-evo-tool/tests/backend-e2e/identity_tasks.rs:291` (`step_transfer_to_addresses`). +- **Preconditions**: ID-001 helper. +- **Scenario**: + 1. Register identity with `≥ 60_000_000` credits (ID-001 with larger funding). + 2. Derive `dest_addr` on the test wallet. + 3. Call `transfer_credits_to_addresses_with_external_signer(identity_id, {dest_addr: 20_000_000}, signer, settings: None)`. + 4. Sync test wallet balances. +- **Assertions**: + - `balances[dest_addr] == 20_000_000` + - Identity balance decreased by `20_000_000 + transfer_fee`. + - Returned `Credits` value equals on-chain transferred amount (the wallet returns the post-fee `Credits` — assert matches `20_000_000`). +- **Negative variants**: + - Transfer to malformed `PlatformAddress` (P2SH that the harness cannot sign for is fine here — it's the destination, not the source) → SDK accepts it; assert balance shows up. + - Insufficient identity balance → typed error. +- **Harness extensions required**: Wave A only. +- **Estimated complexity**: M +- **Rationale**: Closes the ID surface — combined with ID-002 (addresses → identity) and ID-005 (identity → addresses), this exercises the full money-flow loop that wallets actually need to demo. + +#### ID-006 — Refresh and load identity by index +- **Priority**: P1 +- **Wallet feature exercised**: `wallet/identity/network/loading.rs:28` (`load_identity_by_index`); `loading.rs:162` (`refresh_identity`); `discovery.rs:79` (`discover`). +- **DET parallel**: `dash-evo-tool/tests/backend-e2e/identity_tasks.rs:350` (`tc_025_refresh_identity`); `identity_tasks.rs:420` (`tc_027_load_identity`); `identity_tasks.rs:585` (`tc_031_incremental_address_discovery`). +- **Preconditions**: ID-001 helper. +- **Scenario**: + 1. Register identity via ID-001 at `identity_index = 0`. + 2. Drop the test-wallet handle; rebuild a fresh `TestWallet` from the same seed. + 3. Call `discover()` to walk identity indices 0..n until none found. + 4. Call `load_identity_by_index(0)`. + 5. Mutate something off-band (e.g. issue a top-up via ID-002) and call `refresh_identity`. +- **Assertions**: + - `discover()` returns exactly the registered identity. + - `load_identity_by_index(0)` populates the local `IdentityManager` with id, balance, and key set matching the on-chain identity. + - Post-`refresh_identity`, the cached balance reflects the top-up. +- **Negative variants**: + - `load_identity_by_index(1)` for a non-existent identity at that index → returns `Ok(None)` (assert) or typed `NotFound` (whichever the contract specifies — this case will surface that contract). +- **Harness extensions required**: Wave A; helper to rebuild a `TestWallet` from a stored seed (the registry already stores `seed_hex`). +- **Estimated complexity**: M +- **Rationale**: Wallet restart / identity rediscovery is the most-hit path in mobile apps and the most-broken-by-protocol-bumps. ID-006 catches discovery regressions deterministically. + +#### ID-001c — Non-default `StateTransitionSettings` +- **Priority**: P2 +- **Wallet feature exercised**: `wallet/identity/network/register_from_addresses.rs:65`'s `settings: Option` argument; non-default values (e.g. `wait_for_proof = false`, fee multiplier override, signing-key override). +- **DET parallel**: none. +- **Preconditions**: ID-001 helper. +- **Scenario**: register an identity exactly as ID-001 except pass a non-default `StateTransitionSettings`. Run two sub-cases: + 1. `settings: Some(StateTransitionSettings { wait_for_proof: false, .. })`. Expect the call to return as soon as broadcast succeeds, without blocking on proof. + 2. `settings: Some(StateTransitionSettings { fee_multiplier: , .. })`. Expect the on-chain fee to scale by the configured multiplier. +- **Assertions**: + - Sub-case (1): the call's wall-clock duration is bounded below by network RTT and above by a `proof_wait_timeout` it should not have hit; cached identity is "broadcasted, awaiting proof"; on next sync the proof is observed and the change-set finalised. + - Sub-case (2): observed on-chain fee scales as documented (within rounding). +- **Negative variants**: none. +- **Harness extensions required**: Wave A; a "did we wait for proof?" hook on the harness SDK (or a wall-clock-bound check). +- **Estimated complexity**: M +- **Rationale**: Every existing Identity / DPNS / DashPay test passes `settings: None`. The `Some` branch is entirely uncovered; without ID-001c, settings-related fields can be silently misrouted. + +#### ID-005b — `transfer_credits_to_addresses` with empty outputs +- **Priority**: P2 +- **Wallet feature exercised**: `wallet/identity/network/transfer_to_addresses.rs:66` validation gate. +- **DET parallel**: none. +- **Preconditions**: ID-001 helper; identity with non-zero balance. +- **Scenario**: + 1. Register an identity per ID-001 with starting balance `≥ 50_000_000`. + 2. Call `transfer_credits_to_addresses_with_external_signer(identity_id, {}, signer, None)` — empty output map. +- **Assertions**: + - Returns a typed validation error of "at least one output is required" shape (mirror the ID-001 negative-variant message style; pin the exact variant or message). + - No state-transition broadcast. + - Identity balance unchanged. +- **Negative variants**: none — this case IS the empty-input variant. +- **Harness extensions required**: Wave A only. +- **Estimated complexity**: S +- **Rationale**: ID-001 already pins the empty-`inputs` error message exactly. ID-005b mirrors that pin on the empty-`outputs` side, which is currently uncovered. + +#### ID-006b — Identity-key derivation index boundary +- **Priority**: P2 +- **Wallet feature exercised**: identity-key derivation under `wallet/identity/network/identity_handle.rs::derive_ecdsa_identity_auth_keypair_from_master` at `key_index` boundaries. +- **DET parallel**: none direct. +- **Preconditions**: ID-001 helper. +- **Scenario**: + 1. Register an identity with `key_index = 0`. Verify on-chain that the registered HIGH key matches `derive_identity_key(.., key_index = 0, ..)`. + 2. Register a second identity (or `update_identity` add-key on the same identity) with `key_index = DEFAULT_GAP_LIMIT - 1`. Verify the registered key matches the corresponding derivation. + 3. Optionally: attempt `key_index = DEFAULT_GAP_LIMIT` and pin the contract (rejected vs gap grown). +- **Assertions**: each sub-case asserts that the on-chain key bytes match the off-chain DIP-9 derivation at the boundary index. +- **Negative variants**: none. +- **Harness extensions required**: Wave A's `derive_identity_key` helper exposed for `key_index` (in addition to `identity_index`). +- **Estimated complexity**: M +- **Rationale**: ID-006 covers `identity_index` boundaries; `key_index` is the parallel axis and currently uncovered. + +### Tokens (TK) + +The wallet has token operations on the API surface +(`wallet/tokens/wallet.rs` + `wallet/identity/network/tokens/*`).

Register `identity_a` and `identity_b` per ID-001. + 2. Pre-condition: operator pre-funds `identity_a` with `≥ 100` tokens of the configured contract (one-time setup, similar to bank funding). + 3. Call `token_transfer_with_signer(identity_a, contract_id, token_position, identity_b, amount=50)`. + 4. Sync token balances on both. +- **Assertions**: + - `identity_a` token balance decreased by exactly `50`. + - `identity_b` token balance increased by exactly `50`. + - `identity_a` credit balance decreased by `transfer_fee` (token transfer pays in credits, not in tokens). +- **Negative variants**: + - Transfer amount exceeds sender token balance → typed error. + - Transfer with wrong `token_position` → contract-validation error. +- **Harness extensions required**: + - Wave A (Identity signer). + - `Config::token_contract_id` + `token_position` env vars. + - `TestWallet::token_balance(identity_id, contract_id, token_pos)` helper. + - Operator documentation: how to pre-fund tokens (one-time, sibling of bank pre-funding). +- **Estimated complexity**: L +- **Rationale**: Most-used token op. Catches token-amount underflow bugs and credit-fee accounting bugs in one shot. + +#### TK-001b — Token transfer of amount 0 +- **Priority**: P2 +- **Wallet feature exercised**: `wallet/identity/network/tokens/transfer.rs:21` zero-amount boundary. +- **DET parallel**: none. +- **Preconditions**: TK-001 setup (two identities with non-zero token balance on `identity_a`). +- **Scenario**: call `token_transfer_with_signer(identity_a, contract_id, token_position, identity_b, amount=0)`. +- **Assertions**: pin one contract: + - **(a) Reject**: typed validation error of "amount must be positive" shape; no broadcast; balances unchanged. + - **(b) Accept**: broadcast succeeds; both token balances unchanged; only `identity_a` credit balance decreased by `transfer_fee`. +- **Negative variants**: none. +- **Harness extensions required**: TK-001 extensions. +- **Estimated complexity**: S +- **Rationale**: Zero-amount transfers may be valid no-ops or invalid per contract.

Register identity per ID-001. + 2. Wait for the perpetual-distribution interval to advance. + 3. Call `token_claim_with_signer`. +- **Assertions**: + - Token balance increases by the documented per-interval claim amount (operator-supplied env `PLATFORM_WALLET_E2E_TOKEN_CLAIM_AMOUNT`). + - Second claim within the same interval returns a typed "already claimed" error. +- **Negative variants**: claim with no rights → typed error. +- **Harness extensions required**: TK-001 extensions + interval-aware sleep helper (10–60 s). +- **Estimated complexity**: L +- **Rationale**: Perpetual-distribution bugs are silent — balance just doesn't increase.

Pre-seed `registry.json` with a valid entry that includes a future-version field (e.g. `"unknown_field": "future-value"`). + 2. Start the harness; let it perform a normal write that round-trips the registry. +- **Assertions**: + - Harness loads the registry without error. + - On rewrite, the `unknown_field` is preserved byte-equal (forward-compatible: don't strip fields the current code doesn't understand). + - Tests that depend on the entry continue to operate. +- **Negative variants**: none. +- **Harness extensions required**: registry serde must use `#[serde(other)]` / a catch-all field, or otherwise round-trip unknown keys.

Bank-fund `addr_1` with `40_000_000`. + 2. Wrap `wallet.transfer({addr_2: 5_000_000})` in a `tokio::select!` against a controllable cancellation token. + 3. Trigger cancellation **after** the broadcast call returns (i.e. ST hit DAPI) but **before** the proof-fetch completes. Confirm the future is dropped via the cancellation token. + 4. Call `wallet.sync_balances()`. +- **Assertions**: + - Internal wallet state is consistent after the drop: no half-applied change-set, no orphaned in-flight marker that would block the next call. + - Post-`sync_balances`, the wallet observes the broadcasted transfer and records the change-set correctly: `balances[addr_2] == 5_000_000`, `addr_1` decreased by `5_000_000 + fee`. + - A subsequent `wallet.transfer({addr_3: 1_000_000})` succeeds — no duplicate broadcast of the previous transfer, no nonce collision. +- **Negative variants**: + - Cancellation **before** broadcast: assert no broadcast occurred and balances unchanged. +- **Harness extensions required**: a way to inject a cancellation point between broadcast and proof-fetch (likely a test-only hook on the harness SDK or a `select!` wrapper on the wallet call). This is the most invasive of the Harness-G cases; mark as "blocked on cancellation hook" if not yet plumbed. +- **Estimated complexity**: L +- **Rationale**: `tokio::select!` cancellation safety is a documented Tokio footgun. Without an asserted contract, the wallet may corrupt internal state on user-initiated cancellation (e.g. mobile app foregrounding/backgrounding) and only surface as "wallet shows wrong balance after I closed the app". + +### Found-bug pins (Found-NNN) + +Bug-pin cases discovered during a QA-mindset audit of `packages/rs-platform-wallet/src/`. +Each entry names the contract violation, the proof shape that would catch it, +and what the fix should look like. The author of the production fix is a +separate concern; these entries pin the expected behaviour so the regression +becomes a test failure rather than a silent drift. + +#### Found-001 — `auto_select_inputs_for_withdrawal` ignores `min_input_amount` floor +- **Priority**: P2 (bug pin — failure is the proof) +- **Wallet feature exercised**: `wallet/platform_addresses/withdrawal.rs:170` (`auto_select_inputs_for_withdrawal`). +- **Suspected bug**: The withdrawal-side auto-selector iterates every funded address (`balance > 0`) and inserts each into the selected map. Unlike `transfer.rs::auto_select_inputs` (which filters out balances `< min_input_amount`), the withdrawal helper has no `min_input_amount` floor. An address holding fewer credits than the protocol's per-input minimum will be selected, and the resulting transition trips `InputBelowMinimumError` at `validate_structure` time. +- **Preconditions**: a platform payment account holds at least one address with balance `> 0` but `< min_input_amount` (e.g. an address that absorbed dust on a prior partial sync). +- **Scenario**: + 1. Seed account with two funded addresses: `addr_A.balance = 100_000_000`, `addr_B.balance = min_input_amount - 1`. + 2. Call `withdraw(account_index, InputSelection::Auto, ..., DeductFromInput(0))`. +- **Assertions** (the proof shape): + - The selector returns an `Err(PlatformWalletError::AddressOperation(_))` whose message references `min_input_amount`, OR the selector returns `Ok(map)` where every value is `>= min_input_amount`. + - In NEITHER case does it return `Ok(map)` containing `addr_B → (min_input_amount - 1)`. +- **Expected** (after fix): mirror the transfer-side filter — exclude candidates below `min_input_amount` before constructing the input map; if the survivors don't cover the requested fee, error with a descriptive message. +- **Actual** (current code): the function selects `addr_B` unconditionally; the broadcast then fails with a generic protocol-validation error that doesn't name the cause. +- **Severity**: HIGH (per-input minimum is a hard protocol gate; user gets an opaque rejection instead of a clear wallet-side error) +- **Harness extensions required**: `auto_select_inputs_for_withdrawal` is a private helper; the test exercises it indirectly via `withdraw(InputSelection::Auto, ...)` and seeded balances. Needs a way to seed individual platform-payment addresses with a sub-minimum balance — likely via direct `set_address_credit_balance` on `ManagedPlatformAccount` for the test setup. +- **Estimated complexity**: S +- **Rationale**: The transfer path was hardened against this exact failure mode (see `auto_select_inputs` filter). Withdrawal silently drifted out of parity. Real-world trigger: a dust-tier address arrives mid-sync and the user attempts an "auto-select" withdrawal — the wallet builds an unspendable transition. + +#### Found-002 — `auto_select_inputs_for_withdrawal` skips fee-target headroom check +- **Priority**: P2 (bug pin — failure is the proof) +- **Wallet feature exercised**: `wallet/platform_addresses/withdrawal.rs:170-235`. +- **Suspected bug**: The transfer-side `select_inputs_deduct_from_input` performs an explicit "fee target retains ≥ estimated_fee" check (Phase 3) before returning. The withdrawal-side helper checks only the aggregate `accumulated < estimated_fee` — i.e. that the *sum* of all inputs covers the fee. Under `[DeductFromInput(0)]` the fee is taken from the lex-smallest input's *remaining balance*, not the aggregate, so a selection where the lex-smallest input is fully consumed but other inputs cover the difference passes the helper's gate yet fails on chain — the same failure pattern PA-002b / commits `9ea9e7033c` and `687b1f86cd` pinned for transfer. +- **Preconditions**: a withdrawal account with at least one small input that becomes the lex-smallest "fee target" after BTreeMap insertion. +- **Scenario**: + 1. Seed account with `addr_A` (lex-smallest, balance == small amount equal to its own consumption with no fee headroom) and `addr_B` (large balance covering the rest). + 2. Call `withdraw(..., InputSelection::Auto, ..., DeductFromInput(0))`. +- **Assertions** (the proof shape): + - The selector errors with a "fee headroom" message, OR after broadcast `validate_fees_of_event` would return `fee_fully_covered = false` (provable in a unit test by feeding the helper output to `deduct_fee_from_outputs_or_remaining_balance_of_inputs` exactly as PA-006 does for transfer). +- **Expected** (after fix): adopt the transfer helper's Phase-3 headroom check — confirm `lex-smallest-input.balance - lex-smallest-input.consumed >= estimated_fee` before returning. +- **Actual** (current code): the helper performs only an aggregate check; the chain-time deduction misdirects to an empty-remaining input. +- **Severity**: HIGH (drives users into the same chain-time `AddressesNotEnoughFundsError` class as platform #3040) +- **Harness extensions required**: same as Found-001 — fine-grained seeding of platform-payment account balances. A protocol-level reproduction (analogous to `pre_fix_buggy_selector_output_is_rejected_by_protocol_fee_deduction` in transfer's tests) is the simplest proof shape. +- **Estimated complexity**: M +- **Rationale**: Withdrawal lags transfer's hardening; the same regression class will silently re-emerge in withdrawal until the contract is pinned. + +#### Found-003 — `addresses_with_balances` and `total_credits` only see the first platform-payment account +- **Priority**: P2 (bug pin — failure is the proof) +- **Wallet feature exercised**: `wallet/platform_addresses/wallet.rs:233` (`addresses_with_balances`), `wallet/platform_addresses/wallet.rs:271` (`total_credits`). +- **Suspected bug**: Both methods reach for `first_platform_payment_managed_account()` and return data from that single account. The doc comments make no mention of the "first account only" restriction (`addresses_with_balances` says "all platform addresses", `total_credits` says "total platform credits across all addresses"). Wallets with multiple platform-payment accounts (DIP-17 supports this) silently undercount. +- **Preconditions**: a wallet with two or more `PlatformPayment` accounts, each holding a non-zero balance on at least one address. +- **Scenario**: + 1. Construct a wallet with `WalletAccountCreationOptions` that yields two PlatformPayment accounts (account `0` and account `1`). + 2. Fund one address on account `0` with `40_000_000`; fund one address on account `1` with `60_000_000`. + 3. Read `wallet.platform().addresses_with_balances().await` and `wallet.platform().total_credits().await`. +- **Assertions** (the proof shape): + - `addresses_with_balances` returns at least two entries (one from each account). + - `total_credits == 100_000_000` (sum across both accounts). +- **Expected** (after fix): iterate `core_wallet.platform_payment_managed_accounts()` (or equivalent multi-account accessor) and aggregate. +- **Actual** (current code): returns only account-0 data; second account's `60_000_000` is invisible from these accessors. +- **Severity**: MEDIUM (UI-facing; the user sees a "wrong balance" without any error indication) +- **Harness extensions required**: a test wallet builder that requests multiple PlatformPayment accounts at creation. The existing `wallet_factory` defaults to one; a `WalletAccountCreationOptions` variant or test-only setup is needed. +- **Estimated complexity**: S +- **Rationale**: The "first account only" restriction is a load-bearing implicit assumption that nothing in the public API surface tells callers about. Multi-account support is documented at the wallet-creation layer; the readback must match. + +#### Found-004 — `transfer` / `withdraw` / `fund_from_asset_lock` silently fall back to `address_index = 0` on lookup miss +- **Priority**: P2 (bug pin — failure is the proof) +- **Wallet feature exercised**: `wallet/platform_addresses/transfer.rs:157-167`, `wallet/platform_addresses/withdrawal.rs:142-152`, `wallet/platform_addresses/fund_from_asset_lock.rs:130-140`. +- **Suspected bug**: All three call sites build a `PlatformAddressBalanceEntry` whose `address_index` is computed via a `find_map(...).unwrap_or(0)` over the account's address pool. If the address truly is not in the pool (defensive case — e.g. caller passed an address that doesn't belong to the account), the entry persists with `address_index = 0`, mis-attributing the balance update to whichever address actually sits at index 0. The persister then writes the wrong row. +- **Preconditions**: an account containing at least one address at index `0`. A subsequent operation references an address NOT in the pool (e.g. via `Explicit` input that's foreign to this account). +- **Scenario**: + 1. Build account `A` with addresses `addr_at_0`, `addr_at_1`, `addr_at_2`. + 2. Construct a transfer / withdrawal / fund call referencing a `PlatformAddress` that is NOT in any of the account's pools but is otherwise well-formed. + 3. Inspect the returned `PlatformAddressChangeSet`. +- **Assertions** (the proof shape): + - The changeset must NOT contain an entry with `(address: foreign_addr, address_index: 0)` — that's a corrupted persistence row. + - Either the operation rejects with a typed error before producing a changeset entry, OR the entry omits the foreign address entirely. +- **Expected** (after fix): on `find_map(...) == None`, log + skip the entry instead of attributing it to index 0; or fail the call with a typed error pointing at the unknown address. +- **Actual** (current code): the entry is attributed to index 0 and written to the persister. +- **Severity**: MEDIUM (silent data corruption in the persister's address table; downstream readers think `addr_at_0`'s balance is whatever the SDK reported for the foreign address) +- **Harness extensions required**: a way to drive the call site with a foreign `PlatformAddress`. The transfer / fund paths accept `Explicit*` input maps so this is straightforward; the withdrawal path is per-account so requires a similar input-construction helper. +- **Estimated complexity**: S +- **Rationale**: `unwrap_or(0)` on a derivation-index lookup is the canonical "should have been a typed error" pattern. With three call sites identical, the regression class is broad. + +#### Found-005 — `register_from_addresses` / `top_up_from_addresses` discard SDK-returned address balances and nonces +- **Priority**: P2 (bug pin — failure is the proof) +- **Wallet feature exercised**: `wallet/identity/network/register_from_addresses.rs:87-122`, `wallet/identity/network/top_up_from_addresses.rs:58`. +- **Suspected bug**: Both call sites pattern-match the SDK return as `(_address_infos, ...)` and drop the address-info map. `transfer()` and `withdraw()` (in `platform_addresses/`) consume this same map to update local balances + nonces. The TODO comment in `register_from_addresses.rs:139-143` admits the gap. As a result, addresses' cached `(balance, nonce)` go stale immediately after these calls — until the next BLAST sync round resolves them. A second operation against the same address before the sync uses a stale nonce and is rejected. +- **Preconditions**: a platform-funded address with a known nonce. Run two consecutive operations against it. +- **Scenario**: + 1. Fund `addr_A` on test wallet with `60_000_000`. Note the address's nonce (post-funding). + 2. Call `register_from_addresses({addr_A: 30_000_000}, ...)` — this consumes part of addr_A's balance and bumps its nonce on chain. + 3. Without an intervening BLAST sync, immediately call a second operation against `addr_A` (e.g. another `register_from_addresses` or a `transfer`). +- **Assertions** (the proof shape): + - After step 2, `wallet.platform().addresses_with_balances()` reflects `addr_A`'s post-call balance (i.e. NOT the pre-call `60_000_000`). + - The cached nonce for `addr_A` matches the chain-time nonce post-step-2. + - Step 3 succeeds (would fail with a stale-nonce error today). +- **Expected** (after fix): mirror the `transfer()` pattern — walk `address_infos` and update each address's cached `AddressFunds` + emit a `PlatformAddressChangeSet` so the persister sees the updated nonce. +- **Actual** (current code): the map is dropped; local cache stays at pre-call values. +- **Severity**: MEDIUM (causes "spam-click" failures and surprises power users; not silent corruption but slow-to-recover staleness) +- **Harness extensions required**: a way to issue two back-to-back operations against the same input address with no sync between them. +- **Estimated complexity**: M (needs identity-signer + DPNS-style identity setup, then two consecutive identity-funding calls) +- **Rationale**: The TODO comment in the source admits the gap; a test pins it so the comment doesn't outlive the next refactor that touches these files. + +#### Found-006 — `top_up_identity_with_funding` ignores caller-supplied `topup_index` +- **Priority**: P2 (bug pin — failure is the proof) +- **Wallet feature exercised**: `wallet/identity/network/top_up.rs:60-106`. +- **Suspected bug**: The method's doc says `topup_index` is "An incrementing index distinguishing successive top-ups for the same identity". The implementation prefixes the parameter with `_` and the function body derives the funding key path from `identity_index` alone (with a `TODO(platform-wallet)` comment confirming the parameter is unused). Two consecutive top-ups for the same identity therefore derive from the same `(IdentityTopUp, identity_index)` path — yielding the same one-time key address, the same outpoint candidate, and a likely-duplicate asset-lock transaction or nonce collision on the same address. +- **Preconditions**: an identity registered on testnet via the wallet. +- **Scenario**: + 1. Register identity `I` via `register_identity_with_funding_external_signer`. + 2. Call `top_up_identity(&I.id, topup_index=0, amount_duffs=A0, ...)`. + 3. Call `top_up_identity(&I.id, topup_index=1, amount_duffs=A1, ...)` — same identity, fresh `topup_index`. +- **Assertions** (the proof shape): + - The two top-up calls produce DIFFERENT funding-output addresses (re-derived from different paths). + - The two asset-lock transactions have different txids. + - The doc claim about "successive top-ups for the same identity" is honoured — both calls succeed and credit the identity by `A0 + A1` total. +- **Expected** (after fix): wire `topup_index` into the derivation path (or remove the parameter and document the constraint). +- **Actual** (current code): two consecutive top-ups for the same identity share the same derivation context; the second is liable to collide with the first depending on caller behaviour. +- **Severity**: HIGH (the public API has a parameter that does nothing; callers relying on the doc-stated semantics produce broken transactions) +- **Harness extensions required**: identity setup; access to the asset-lock transaction details (currently inside `AssetLockManager`). +- **Estimated complexity**: M +- **Rationale**: A parameter that's documented as load-bearing but discarded by the implementation is a contract violation that no test currently catches. The TODO in the source admits the gap; a test makes it actionable. + +#### Found-007 — `PlatformAddressSyncManager::start` lacks a generation guard so a fast `start()` → `stop()` → `start()` can spawn parallel sync threads +- **Priority**: P2 (bug pin — failure is the proof) +- **Wallet feature exercised**: `manager/platform_address_sync.rs:189-224` (`start`). +- **Suspected bug**: `start()` checks `guard.is_some()` and bails early, then installs a fresh cancel token. On loop exit the spawned thread unconditionally writes `*guard = None;`. There is no generation counter (unlike `IdentitySyncManager::start`, which does have one). Trace: `start()` spawns thread A → `stop()` cancels A → `start()` spawns thread B (guard now Some(B)) → thread A's loop finally exits and overwrites `guard = None`. Thread B is still running, but `is_running()` reports `false` and a third `start()` will spawn thread C. Multiple sync threads can run concurrently against the same `wallets` map, each issuing GRPC calls to DAPI. +- **Preconditions**: a manager whose `start()` returns quickly enough to interleave a `stop()` and another `start()` before the original thread observes cancellation. +- **Scenario**: + 1. Build a manager with one registered wallet and a reachable DAPI endpoint. + 2. Call `start()`. + 3. Immediately call `stop()`. + 4. Immediately call `start()` again (before thread A's first sync round completes). + 5. Wait for thread A to observe its cancel token (it will, eventually) and clean up. + 6. Inspect `is_running()` and the actual thread count. +- **Assertions** (the proof shape): + - At every moment after step 4, AT MOST one platform-address-sync thread is running. + - `is_running() == true` for the entire window between step 4 and a later `stop()`. + - After thread A exits in step 5, `is_running()` does NOT drop to `false` (because thread B is still active). +- **Expected** (after fix): adopt `IdentitySyncManager`'s generation-counter pattern — the spawned thread only clears the guard if its own generation matches the latest installed one. +- **Actual** (current code): thread A unconditionally clears the guard on exit, masking thread B's existence to `is_running()`. +- **Severity**: MEDIUM (parallel sync threads cause duplicate DAPI calls, write contention on the wallet manager lock, and inflated rate-limit usage; not data corruption but operationally noisy) +- **Harness extensions required**: a way to count active "platform-address-sync" threads (`std::thread::Builder::name`) or to wedge a sync iteration so cancellation is observable but slow. The simplest proof shape is a counter that the sync routine increments per pass; if two threads run concurrently the counter advances faster than the interval. +- **Estimated complexity**: M +- **Rationale**: `IdentitySyncManager` already has the right pattern. The asymmetry between the two managers is the bug. + +#### Found-008 — `LockNotifyHandler` uses `notify_waiters()` so a lock event arriving in the check / wait gap of `wait_for_proof` is dropped +- **Priority**: P2 (bug pin — failure is the proof) +- **Wallet feature exercised**: `wallet/asset_lock/lock_notify_handler.rs:30` (`notify_waiters()`); `wallet/asset_lock/sync/proof.rs:287-337` (`wait_for_proof`'s check-then-await loop). +- **Suspected bug**: `LockNotifyHandler::on_sync_event` calls `Notify::notify_waiters()`, which wakes only currently-registered waiters and produces no permit. `wait_for_proof` runs a check-then-await loop: read state under a read lock, drop the lock, then call `lock_notify.notified().await`. If a lock event fires in the gap between the state check and the registration of the next `notified()` future, no waiter is currently registered, the notification is discarded, and the waiter sleeps until the next event or the timeout. +- **Preconditions**: SPV emits exactly one `InstantLockReceived` for the watched outpoint at a precise moment. +- **Scenario**: + 1. Tracked asset lock `OL` is in `Broadcast` state. + 2. Test thread calls `wait_for_proof(&OL.out_point, timeout=300s)`. + 3. The sequence (deterministic for the test): + - Wait for `wait_for_proof` to enter the loop and complete its first state check (no proof yet, still `Broadcast`). + - BEFORE `wait_for_proof` reaches `lock_notify.notified()`, drive `LockNotifyHandler::on_sync_event(InstantLockReceived(OL))` exactly once. + - Update the underlying `TransactionContext` to `InstantSend(lock)` AT THE SAME TIME (so a re-check would succeed). +- **Assertions** (the proof shape): + - `wait_for_proof` returns `Ok(InstantAssetLockProof(...))` within `1s` (i.e. without waiting for the timeout). + - Counter-assertion if buggy: it sleeps until either a follow-up notify or `FinalityTimeout`. +- **Expected** (after fix): use `Notify::notify_one()` (which keeps a permit if no waiter is registered) or call `notified()` BEFORE the state check (so the future is registered before the check happens, per Tokio's documented "intended use"). +- **Actual** (current code): a single missed notification stalls the waiter. +- **Severity**: HIGH (asset-lock proof flow is on the critical path of identity registration / top-up; a stalled wait surfaces as long timeouts followed by spurious "asset lock expired" errors) +- **Harness extensions required**: a test handle on `LockNotifyHandler` (it's already constructed with an `Arc`); a way to drive the handler synchronously with a controlled state mutation. The wait-for-proof check uses `wallet_manager`, so the test must mutate the tracked record's `TransactionContext` before re-driving the handler. +- **Estimated complexity**: M +- **Rationale**: This is the textbook `Notify` footgun — `notify_waiters` doesn't store a permit, so check-then-await is a missed-wakeup. The asset-lock flow is exactly the place where one missed wakeup turns a 5-second proof wait into a 5-minute hang. + +#### Found-009 — wallet-event adapter swallows `RecvError::Lagged` events without compensating recovery +- **Priority**: P2 (bug pin — failure is the proof) +- **Wallet feature exercised**: `changeset/core_bridge.rs:71-115` (the `tokio::select!` loop in `spawn_wallet_event_adapter`). +- **Suspected bug**: On `Err(RecvError::Lagged(n))` the loop logs a warning and continues. The dropped events are gone — `WalletEvent::TransactionDetected`, `BlockProcessed`, etc. that the broadcast channel discarded never reach the persister. Persisted state then lags reality, and there's no compensating mechanism to refetch them. +- **Preconditions**: the broadcast channel's capacity is exceeded (many events fired in a tight burst, e.g. an SPV catch-up with a lot of UTXO changes). +- **Scenario**: + 1. Configure the persister to record every `store(..., cs)` it sees. + 2. Drive the upstream broadcast channel with `(channel_capacity + 10)` distinct events in a tight burst, each with a unique `wallet_id` or `txid` so the persister can tell them apart. + 3. Wait for the loop to drain. +- **Assertions** (the proof shape): + - The persister observes ALL injected events. Or, equivalently, at least one of: (a) the loop's recovery mechanism re-emits the dropped events (e.g. by walking `wallet_manager` state and emitting a synthetic catch-up changeset), (b) the loop returns / signals an error to the caller so the application can react. Today neither happens. +- **Expected** (after fix): on `Lagged(n)`, either re-subscribe and emit a "full state snapshot" changeset, or escalate the error (e.g. via a status channel) so the operator can issue an explicit re-sync. Silent loss is not OK because the persister diverges from chain reality with no signal. +- **Actual** (current code): events are gone, only a warning log remains. +- **Severity**: MEDIUM (losing core-wallet events causes the persister's stored state to diverge silently from the in-memory `WalletManager` state) +- **Harness extensions required**: a way to construct a small-capacity `tokio::sync::broadcast::Sender` and inject events directly; or an instrumented wallet manager that exposes the broadcast for tests. +- **Estimated complexity**: M +- **Rationale**: `Lagged` is rare but not impossible. When it happens, the wallet's persisted state silently goes wrong. Documenting the contract one way or the other (re-emit / escalate / accept loss) is the minimum bar. + +#### Found-010 — `PlatformAddressChangeSet::apply` ignores `funds.nonce` so persister-only nonce state can drift behind balance +- **Priority**: P2 (bug pin — failure is the proof) +- **Wallet feature exercised**: `wallet/apply.rs:259-273` (the `platform_addresses` apply branch). +- **Suspected bug**: The apply path walks `addr_cs.addresses` and writes only `entry.funds.balance` via `set_address_credit_balance`. The `nonce` field on `entry.funds` is dropped — the comment at line 266-270 admits this and points at "evo-tool's platform_address_balances table" as the alleged consumer of the nonce. But that consumption only happens via the FFI persister callback; pure in-memory replay (e.g. tests, restart-into-memory) loses the nonce and a subsequent operation against the same address will use a stale value. +- **Preconditions**: a persister round-trip whose only consumer is `apply_changeset` (no FFI sidecar). +- **Scenario**: + 1. Source `PlatformWalletInfo` `A` has `addr_X` with `(balance=50, nonce=7)`. + 2. Snapshot `A` into a `PlatformAddressChangeSet` and apply it to a fresh `PlatformWalletInfo` `B`. + 3. Read `B`'s cached state for `addr_X`. +- **Assertions** (the proof shape): + - `B`'s cached nonce for `addr_X == 7`. + - Counter-assertion if buggy: `B`'s nonce reads back as `0` (the default) because apply never wrote it. +- **Expected** (after fix): persist + apply the nonce alongside the balance — extend `set_address_credit_balance` to also accept the nonce, or add a sibling write. +- **Actual** (current code): apply discards the nonce. Test harnesses replaying a changeset see balance-only state. +- **Severity**: MEDIUM (only bites pure-Rust persisters and tests; FFI consumers are unaffected because they read the changeset directly) +- **Harness extensions required**: ability to read back per-address nonce from `ManagedPlatformAccount`. If no such accessor exists today, the test would need a new one. +- **Estimated complexity**: S +- **Rationale**: The contract is "apply replays the changeset onto state". Replaying balance only is a partial replay; the silent-drop of nonce is a documentation gap that masquerades as design. + +#### Found-011 — `IdentityChangeSet::merge` documents commutativity but `insert + tombstone` for the same key resolves to "removed" regardless of submission order +- **Priority**: P2 (bug pin — failure is the proof) +- **Wallet feature exercised**: `changeset/changeset.rs:336-421` (`IdentityChangeSet::merge`); `wallet/apply.rs:127-143` (the apply order: insert then remove). +- **Suspected bug**: The `Merge` trait's docstring says changesets are "commutative and associative". `IdentityChangeSet::merge` extends `identities` (inserts) and `removed` (tombstones) independently with no insert-vs-tombstone resolution. The apply order is "insert first, then remove", so a merged changeset that contains BOTH an insert and a tombstone for identity `id_X` always resolves to "removed", regardless of which side was passed first to `merge`. The latent contract violation: `A.merge(B)` then apply ≠ `B.merge(A)` then apply for the case `A = {insert id_X}`, `B = {tombstone id_X}` (both produce "removed"), but the merger has no way to express "the insert wins because it came later". The docstring on the changeset itself acknowledges the hazard ("Merge ordering hazard"); the trait-level docstring still claims commutativity. One of the two is wrong. +- **Preconditions**: two changesets that disagree on a single identity (one inserts, one removes). +- **Scenario**: + 1. Build `cs_insert` containing `identities: {id_X → entry}` only. + 2. Build `cs_remove` containing `removed: {id_X}` only. + 3. Compute state_AB by merging cs_insert into a copy, then merging cs_remove, then applying. + 4. Compute state_BA by merging cs_remove into a copy, then merging cs_insert, then applying. +- **Assertions** (the proof shape): + - If commutativity is the contract: state_AB == state_BA AND for at least one of them id_X is present (non-vacuous). Today both end up "removed", so the contract is "tombstone wins". State the rule in the docstring. + - If "tombstone wins" is the contract: docstring on the `Merge` trait must say so explicitly; the test pins the ordering. +- **Expected** (after fix): pick one — either `merge` resolves the conflict by last-seen (A.merge(B) ⇒ tombstone wins because it came later in `B`; B.merge(A) ⇒ insert wins because it came later in `A`), or document "tombstone always wins regardless of merge order" and remove the commutativity claim. +- **Actual** (current code): tombstone always wins and the docstring claims commutativity; one of the two is misleading. +- **Severity**: LOW (no current emitter produces both insert and tombstone for the same key in one mutation, per the in-source comment, but the latent footgun is documented as if it isn't a footgun) +- **Harness extensions required**: none — pure unit-test-shaped. +- **Estimated complexity**: S +- **Rationale**: A "commutative" claim that doesn't hold for the simplest counter-example is a documentation bug that misleads future emitters. Pinning the actual semantics in a test forces the doc to match reality. + +#### Found-012 — `validate_or_upgrade_proof` and `wait_for_proof` only consult `standard_bip44_accounts`, missing CoinJoin / non-BIP-44 funding accounts +- **Priority**: P2 (bug pin — failure is the proof) +- **Wallet feature exercised**: `wallet/asset_lock/sync/proof.rs:43-54` (`validate_or_upgrade_proof`); `wallet/asset_lock/sync/proof.rs:289-322` (`wait_for_proof`); `wallet/asset_lock/sync/recovery.rs:104-110` (`resolve_status_from_info`). +- **Suspected bug**: All three lookups walk `info.core_wallet.accounts.standard_bip44_accounts.get(&account_index)` and bail with "Transaction not found" if the BIP-44 lookup misses. But `account_index` on the tracked lock can refer to a CoinJoin account, an identity account, or any non-BIP-44 funding source. A real CoinJoin-funded asset lock would have its tx in `coinjoin_accounts` (or wherever), not `standard_bip44_accounts`. The wallet then can't resolve the chain status, can't upgrade IS to CL, and `wait_for_proof` returns "transaction not found" even though the chain has the tx. +- **Preconditions**: an asset lock funded from a non-BIP-44 account. +- **Scenario**: + 1. Track a `TrackedAssetLock` whose `account_index` corresponds to a non-BIP-44 account containing the asset-lock tx. + 2. Call `wait_for_proof(&out_point, timeout=10s)`. +- **Assertions** (the proof shape): + - `wait_for_proof` returns `Ok(_)` (the proof) within the timeout, OR errors with a CLEAR account-type-mismatch message — never a generic "Transaction not found in account N" message that masks the real cause. +- **Expected** (after fix): walk every account collection, not just `standard_bip44_accounts`; or carry the account *kind* alongside `account_index` on `TrackedAssetLock`. +- **Actual** (current code): non-BIP-44 funded asset locks silently fail proof discovery. +- **Severity**: MEDIUM (impacts CoinJoin / shielded users; the failure mode is "asset lock never resolves" with a misleading error) +- **Harness extensions required**: ability to register a CoinJoin or non-BIP-44 account on the test wallet and seed a tx into its `transactions` map. +- **Estimated complexity**: M +- **Rationale**: Hardcoding `standard_bip44_accounts` in three places means the bug class spans the entire asset-lock proof pipeline. Pinning the contract on at least the proof-wait path catches a future shielded / CoinJoin asset-lock effort. + +#### Found-013 — `recover_asset_lock_blocking` swallows every error and returns `()` — silent recovery failure +- **Priority**: P2 (bug pin — failure is the proof) +- **Wallet feature exercised**: `wallet/asset_lock/sync/recovery.rs:36-88` (`recover_asset_lock_blocking`). +- **Suspected bug**: The function returns `()`; every failure path is a silent `return`: `wallet_id` not in manager → silent return; lock already tracked → silent return; persister `store` failure → logged and discarded inside `queue_asset_lock_changeset`. There is no signal to the caller that recovery either ran successfully or failed — the doc neither mentions success/failure nor offers a query path to check whether the lock is now tracked. +- **Preconditions**: a recovery attempt against a wallet that doesn't exist in the manager. +- **Scenario**: + 1. Construct an `AssetLockManager` whose `wallet_id` was deliberately removed from the wallet manager. + 2. Call `recover_asset_lock_blocking(...)`. +- **Assertions** (the proof shape): + - The caller can detect the failure — either via a `Result<(), _>` return type, or a follow-up `is_tracked` check that reflects "no, the recovery did not land". + - Today: the function returns `()`; the caller has no way to distinguish "recovery succeeded" from "wallet was missing". +- **Expected** (after fix): change the signature to `Result<(), PlatformWalletError>` (matching the rest of this module's surface), or document explicitly that the function is best-effort and provide a sibling `is_tracked` accessor for confirmation. +- **Actual** (current code): silent failure on `wallet_id` miss; the test harness can't distinguish a successful recovery from a no-op. +- **Severity**: LOW (a recovery failure should be loud; silent swallow is poor ergonomics rather than data corruption — but evo-tool / DET-style callers may rely on this contract) +- **Harness extensions required**: an `is_tracked` query on `AssetLockManager` (likely already exists via `list_tracked_locks`). +- **Estimated complexity**: S +- **Rationale**: `pub fn ... -> ()` on an operation that has multiple distinct failure modes is a documentation bug; pin the contract one way or the other. + +#### Found-014 — `transfer_credits_with_external_signer` never updates the receiver's local balance even when the receiver is wallet-owned +- **Priority**: P2 (bug pin — failure is the proof) +- **Wallet feature exercised**: `wallet/identity/network/transfer.rs:74-138`. +- **Suspected bug**: The SDK call returns `(sender_balance, receiver_balance)`; the wallet uses only `sender_balance` and pattern-matches the receiver as `_receiver_balance`. If the receiver identity is also owned by this wallet (a wallet hosting two identities is the canonical case), its local cached balance falls out of sync until the next identity sync round. +- **Preconditions**: a wallet hosting two identities `I_send` and `I_recv`. Both are managed by the local `IdentityManager`. +- **Scenario**: + 1. Register both `I_send` and `I_recv` against the same wallet. + 2. Record both identities' cached balances pre-transfer. + 3. Call `transfer_credits_with_external_signer(I_send, I_recv, amount, ...)`. + 4. Read both cached balances post-call (no intervening sync). +- **Assertions** (the proof shape): + - `I_send.cached_balance` decreased by `amount + fee` (call returns `sender_balance`, so this side updates). + - `I_recv.cached_balance` increased by `amount` exactly. + - Counter-assertion if buggy: `I_recv.cached_balance` is unchanged from its pre-call value. +- **Expected** (after fix): if `I_recv` is in the local `IdentityManager`, write `set_balance(receiver_balance)` for it too and emit a snapshot changeset. +- **Actual** (current code): receiver-side cache is stale until the next sync; UI reads show the wrong balance for the receiver. +- **Severity**: MEDIUM (UI staleness for self-transfers; not data corruption, but a contract violation since the SDK explicitly reports the receiver balance and the wallet has it on hand) +- **Harness extensions required**: identity setup with two wallet-owned identities (Wave A blocker). +- **Estimated complexity**: S +- **Rationale**: The SDK pattern-binds the receiver balance specifically so the wallet can use it. Discarding it via `_receiver_balance` is a small but precise contract miss. + +#### Found-015 — `load_from_persistor` leaves a partially registered wallet in `wallet_manager` when `wallet_id` mismatches +- **Priority**: P2 (bug pin — failure is the proof) +- **Wallet feature exercised**: `manager/load.rs:69-85`. +- **Suspected bug**: The load loop calls `wm.insert_wallet(wallet, platform_info)` which yields an internally-recomputed `wallet_id`. Immediately afterwards the code compares against `expected_wallet_id` and returns an `Err` if they differ. But by that point the wallet has already been inserted into `self.wallet_manager`. The error-return short-circuits any subsequent rollback, so the manager ends up holding a wallet whose id doesn't match the persisted record — and the `self.wallets` map (the public registry) doesn't have it. Subsequent reads via `wallets.get(...)` return `None` while sync paths see the stale entry. +- **Preconditions**: a persister whose load returns a `(expected_wallet_id, wallet_state)` pair where `expected_wallet_id` != `Wallet::compute_id(wallet_state.wallet)`. (Trivially constructible in tests.) +- **Scenario**: + 1. Build a `ClientStartState` with `wallets[expected_id] = state` where `state.wallet`'s recomputed id is `actual_id != expected_id`. + 2. Call `manager.load_from_persistor()` and observe the error. + 3. Inspect `manager.wallet_manager` (count of wallets) and `manager.wallets` (count of public-registered wallets). +- **Assertions** (the proof shape): + - On error from `load_from_persistor`, both `wallet_manager` and `self.wallets` contain ZERO wallets — neither was partially populated. + - Counter-assertion if buggy: `wallet_manager` contains ONE wallet (the partial insert) while `self.wallets` is empty. +- **Expected** (after fix): roll back the `wm.insert_wallet` (call `wm.remove_wallet(wallet_id)`) before returning the error, or perform the id check BEFORE inserting. +- **Actual** (current code): the manager is left in a half-loaded state where the inner manager and the outer registry disagree. +- **Severity**: MEDIUM (only triggered by corrupted persisted state, but when it triggers the wallet manager is operationally inconsistent) +- **Harness extensions required**: a stub persister that returns a malformed `ClientStartState`. +- **Estimated complexity**: M +- **Rationale**: Half-loaded states lead to the worst class of bug — the manager's internal invariant ("every entry in `wallet_manager` has a matching `Arc` in `self.wallets`") is silently broken. + +#### Found-016 — `remove_wallet` removes from `self.wallets` then `self.wallet_manager` non-atomically, leaving a window where readers see only one of the two +- **Priority**: P2 (bug pin — failure is the proof) +- **Wallet feature exercised**: `manager/wallet_lifecycle.rs:322-337`. +- **Suspected bug**: The function takes the `self.wallets` write lock, removes the wallet, drops the lock, then takes the `self.wallet_manager` write lock and removes from there. Between the two operations, a concurrent task can read `self.wallet_manager` (via e.g. a sync routine) and find the wallet still present, while `self.wallets` no longer has it. The sync routine then queries provider state for a wallet it can't find via the public registry — which manifests as `WalletNotFound` deep inside an unrelated callsite. +- **Preconditions**: at least one concurrent reader on `self.wallet_manager` while `remove_wallet` is in progress. +- **Scenario**: + 1. Register a wallet `W` with the manager. + 2. Spawn task `T1`: in a tight loop, take `wallet_manager.read()` and check whether `W` is present; record both that result and the result of `self.wallets.read()` for the same wallet. + 3. From the main task, call `manager.remove_wallet(&W.id)`. + 4. Stop `T1`. +- **Assertions** (the proof shape): + - For every observation `T1` made: either both registries report present, or both report absent. Never one-of-two. + - Counter-assertion if buggy: at least one observation shows `wallet_manager` present, `self.wallets` absent. +- **Expected** (after fix): perform both removes under a coordinated lock or document the transient inconsistency window. Operations that depend on cross-registry consistency must guard against it. +- **Actual** (current code): a small but real window of inconsistency. +- **Severity**: MEDIUM (race window is small but the resulting `WalletNotFound` errors look like spontaneous failures at unrelated call sites) +- **Harness extensions required**: a way to wedge a concurrent reader with deterministic interleaving (e.g. a `tokio::sync::Barrier` injected for tests). +- **Estimated complexity**: M +- **Rationale**: Two-registry models (here, the inner `WalletManager` plus the outer `Arc` registry) are a classic source of inconsistency windows. The fix is invariant-driven; the test pins the invariant. + +#### Found-017 — `register_wallet` registers wallet in memory even when persister `store` returns `Err` — vanishes on next launch +- **Priority**: P2 (bug pin — failure is the proof) +- **Wallet feature exercised**: `manager/wallet_lifecycle.rs:238-244`, `manager/wallet_lifecycle.rs:296-298`. +- **Suspected bug**: The persister is invoked to store the registration changeset (metadata + per-account specs + per-pool snapshots). On failure the code logs and proceeds to insert the wallet into `self.wallets`. The wallet is fully usable in the current process but on next launch the persister has no record of it — the user-visible effect is "I imported my wallet, used it, restarted the app, and the wallet is gone". +- **Preconditions**: a persister whose `store` returns an error for the registration round. +- **Scenario**: + 1. Build a manager with a stub persister that fails (`store(...) → Err(_)`) on its first call. + 2. Call `create_wallet_from_mnemonic(...)`. + 3. Inspect the result and the manager state. +- **Assertions** (the proof shape): + - EITHER `create_wallet_from_mnemonic` returns `Err(_)` so the caller knows the wallet won't survive a restart, AND the manager state is rolled back (no entry in `self.wallets`, no entry in `self.wallet_manager`). + - OR the function succeeds AND the persister failure is exposed via a status / event channel the caller can subscribe to. A silent log isn't sufficient. +- **Expected** (after fix): treat the registration `store` as load-bearing — fail the registration and roll back the in-memory state on persister error. +- **Actual** (current code): the registration silently proceeds; the user discovers the loss only on next launch. +- **Severity**: HIGH (data loss class — a successful-looking wallet import that doesn't survive restart) +- **Harness extensions required**: a stub persister with a configurable failure mode. +- **Estimated complexity**: S +- **Rationale**: The current code path assumes the persister is "best-effort". For the registration-round changeset specifically, this assumption is wrong — without that record, the wallet is unrecoverable. + +#### Found-018 — `PlatformAddressChangeSet::merge` documents fee semantics as "fee paid by the transfer that produced this changeset" but actually accumulates fees across merged changesets +- **Priority**: P2 (bug pin — failure is the proof) +- **Wallet feature exercised**: `changeset/changeset.rs:586-635` (`PlatformAddressChangeSet::fee_paid`, `Merge::merge`). +- **Suspected bug**: The `fee` field's docstring says "Fee paid by the transfer that produced this changeset, in credits." (singular). `fee_paid()` returns `self.fee`. But `merge` does `self.fee = self.fee.saturating_add(other.fee)` — so a merged changeset's `fee_paid()` returns the sum of fees across multiple transfers. A consumer that calls `fee_paid()` on a merged changeset and expects "the fee for ONE transfer" gets a misleading number with no way to tell. +- **Preconditions**: two changesets, each with a non-zero `fee`. +- **Scenario**: + 1. Build `cs_a` with `fee = 100_000`. + 2. Build `cs_b` with `fee = 200_000`. + 3. Compute `cs_a.merge(cs_b)`. + 4. Read `cs_a.fee_paid()`. +- **Assertions** (the proof shape): + - Pick one — and document the choice: + - (a) `fee_paid()` on a merged changeset is the sum: `300_000`. Then rename / re-document the field to "total fee paid across operations in this batch". + - (b) `fee_paid()` is the fee of a single transfer; `merge` should preserve it via last-write-wins or refuse to merge non-zero fees. Then document and enforce. + - Today: `fee_paid()` returns `300_000` while the docstring says "fee paid by the transfer that produced this changeset" — internally inconsistent. +- **Expected** (after fix): rename the docstring or change the merge policy. The two are at war. +- **Actual** (current code): consumers reading `fee_paid()` on a merged changeset can mis-count the per-transfer fee. +- **Severity**: LOW (only callers reading the fee accessor on a merged changeset are affected; the changeset is mostly consumed pre-merge) +- **Harness extensions required**: none — pure unit-test. +- **Estimated complexity**: S +- **Rationale**: Two facts in the source disagree (docstring vs merge behaviour).

The cache itself was populated at construction in `SimpleSigner::from_seed_for_identity` (`packages/simple-signer/src/signer.rs:235`) keyed by `ripemd160_sha256(&pubkey.serialize())` — i.e. RIPEMD160(SHA256(raw 33-byte secp256k1 pubkey)). For `KeyType::ECDSA_SECP256K1` the lookup matches: `key.data()` is the raw 33-byte pubkey, hashing it once yields the cache key. For `KeyType::ECDSA_HASH160` the lookup does NOT match: `key.data()` is already a 20-byte `ripemd160_sha256(pubkey)` per `KeyType::public_key_data_from_private_key_data` and `KeyType::default_size` (`packages/rs-dpp/src/identity/identity_public_key/key_type.rs:59,244`). The impl hashes that 20-byte hash *again*, producing `ripemd160_sha256(ripemd160_sha256(pubkey))` ≠ stored key. The match arms at lines 90 and 116 explicitly admit `ECDSA_HASH160` as supported, so the type signature lies — every call against an `ECDSA_HASH160` key returns `can_sign_with == false` and `sign(..) == Err(ProtocolError::Generic("identity key {hex} not in pre-derived gap window"))` regardless of whether the underlying secret is in the cache. +- **Preconditions**: an `IdentityPublicKey` with `key_type == ECDSA_HASH160` whose `data` is `ripemd160_sha256(pubkey)` for a pubkey derived at one of the pre-cached gap-window slots `(identity_index, key_index ∈ 0..DEFAULT_GAP_LIMIT)`. +- **Scenario** (pure unit test on the harness signer — no chain required): + 1.

Probe both: + - `signer.can_sign_with(&key_secp)` and `signer.sign(&key_secp, b"msg").await` + - `signer.can_sign_with(&key_h160)` and `signer.sign(&key_h160, b"msg").await` +- **Assertions** (the proof shape): + - `signer.can_sign_with(&key_secp) == true` AND `signer.sign(&key_secp, b"msg").await.is_ok()` (sanity baseline — proves the cache IS populated for this slot). + - `signer.can_sign_with(&key_h160) == true` AND `signer.sign(&key_h160, b"msg").await.is_ok()` (the contract — `ECDSA_HASH160` is whitelisted by both match arms, so it must round-trip). + - Counter-assertion if buggy (today's behaviour): `signer.can_sign_with(&key_h160) == false` AND `signer.sign(&key_h160, b"msg").await` returns `Err(ProtocolError::Generic(msg))` where `msg.contains("not in pre-derived gap window")`. +- **Expected** (after fix): branch on `key.key_type()` before computing the cache key — for `ECDSA_HASH160` the lookup key is `key.data()` *as-is* (it's already the 20-byte hash); for `ECDSA_SECP256K1` it remains `ripemd160_sha256(key.data())`. Mirror the same fix in both `lookup_identity_secret` and `can_sign_with`. Equivalent fix: reject `ECDSA_HASH160` with a clear `unsupported key type` error and remove it from the match arms — the harness only ever produces `ECDSA_SECP256K1` keys via `derive_identity_key`, so `ECDSA_HASH160` support is currently aspirational dead code. +- **Actual** (current code): the harness signer claims to support `ECDSA_HASH160` (match arms at signer.rs:90 and signer.rs:116) but the lookup hashes the already-hashed `data` and fails every probe. The bug never triggers in *current* harness usage because `derive_identity_key` (signer.rs:182-191) hard-codes `key_type = ECDSA_SECP256K1` — but any future test that registers an identity with a hash-typed key, or any production caller that re-uses this signer (e.g. an SDK example wired to a chain identity that was registered by another wallet with an `ECDSA_HASH160` key), trips it. +- **Harness extensions required**: none — pure unit test on `SeedBackedIdentitySigner`. `derive_ecdsa_identity_auth_keypair_from_master` is already exposed via `platform_wallet::wallet::identity::network` (used by `derive_identity_key`). +- **Estimated complexity**: S +- **Rationale**: This is a "the type signature lies" bug. The match arms admit two key types; one of them silently never works. Either fix the lookup or shrink the match. Without a pin, the discrepancy survives until a real consumer hits it — and that consumer's failure mode is a confusing `not in pre-derived gap window` error on a key that demonstrably *is* in the gap window. The hash-level confusion (raw pubkey vs `ripemd160_sha256(pubkey)` vs `ripemd160_sha256(ripemd160_sha256(pubkey))`) is exactly the class of bug a pure-data unit test pins cheaply. + +--- + +## 4. Harness extension roadmap + +Aggregating "Harness extensions required" across §3 and proposing a build +order. Each wave unlocks the cases listed. + +### Wave A — Identity signer + identity setup helpers +- Add `SeedBackedIdentitySigner` implementing `Signer` in `framework/signer.rs` (DIP-9 derivation per `derive_ecdsa_identity_auth_keypair_from_master` at `wallet/identity/network/identity_handle.rs:143`). +- Add `derive_identity_key(seed_bytes, network, identity_index, key_index, purpose, security_level) -> IdentityPublicKey` test helper. +- Add `TestWallet::register_identity_from_addresses(funding: Credits) -> Identity` helper that builds the placeholder, calls `register_from_addresses`, and waits for on-chain visibility. +- Add `wait_for_identity_balance(identity_id, expected, timeout)` in `framework/wait.rs`. +- **Unlocks**: ID-001, ID-001c, ID-002, ID-003, ID-004, ID-005, ID-005b, ID-006, ID-006b, DPNS-001, DPNS-001b, DPNS-001c, DPNS-002 (partial), CT-001, DP-001, DP-001b, DP-001c, DP-002, DP-003, TK-001, TK-001b, TK-002, TK-003, TK-004, CN-001. + +### Wave B — Multi-identity per setup +- Extend `setup()` to accept `setup_with_n_identities(n: u32) -> SetupGuard { test_wallet, identities: Vec }`. +- **Unlocks**: ID-003, DP-002, DP-003. +- **Cost**: Wave A pre-requisite; ~150 LoC. + +### Wave C — Contract fixture loader +- `tests/fixtures/contracts/` directory + `framework::fixtures::load_contract(name)` helper. +- One canonical `minimal.json` (one doc type, two scalar fields). +- **Unlocks**: CT-001, CT-002, CT-003. + +### Wave D — Token contract operator config +- `Config::token_contract_id`, `Config::token_position`, optional `Config::token_claim_amount`. +- Operator pre-funds tokens to the bank-derived identity (one-time, README'd next to bank pre-funding). +- **Unlocks**: TK-001, TK-001b, TK-002, TK-003, TK-004. + +### Wave E — SPV re-enablement (Task #15) +- Uncomment SPV block in `harness.rs:200-218`; swap `TrustedHttpContextProvider` → `SpvContextProvider`. +- Add `SpvHealth::status()` accessor to manager. +- Add Core-funded test wallet helper (faucet integration). +- **Unlocks**: CR-001, CR-002, CR-003. + +### Wave F — Test-only utility helpers +- `TestWallet::transfer_with_inputs` (PA-002 negative variant; PA-004b exact-balance setup). +- `TestWallet::transfer_capturing_st_bytes` (PA-006, PA-006b). +- `TestWallet::estimate_transfer_fee` (PA-002b). +- `Bank::total_credits` accessor exposed (already exists, just lift to public re-export if not). +- `Bank::with_balance_for_test` constructor (PA-010). +- `TestRegistry::get_status(wallet_id)` (PA-004). +- `FUNDING_MUTEX` instrumentation hook (PA-008c). +- "Did we broadcast?" hook on the harness SDK (PA-004c, PA-013). +- Cancellation-point hook between broadcast and proof-fetch (Harness-G4). +- Test DAPI proxy / `httpmock` adapter (PA-013). +- **Unlocks**: PA-002 (negative), PA-002b, PA-004 (full assertions), PA-004b, PA-004c, PA-006, PA-006b, PA-008c, PA-009, PA-010, PA-011, PA-012, PA-013, Harness-G1a, Harness-G1b, Harness-G4. +- **Cost**: ~200-400 LoC across multiple commits; the test-DAPI-proxy and cancellation-hook items are non-trivial and can land late. + +**Recommended build order**: Wave A first (highest leverage — unblocks 25+ cases), then Wave F's cheap helpers (estimate-fee, transfer-with-inputs, registry status, FUNDING_MUTEX hook) which unblock most P2 PA cases, then Wave C, then Wave B as ID-003/DP-002 land. Wave F's expensive items (test DAPI proxy, cancellation hook) and Waves D/E are independent and can run in parallel with the others once a champion is assigned. + +### Wallet-API gap notes (follow-up issues) + +While drafting §3 the following minor public-API gaps were noted. None block +the spec but each would simplify a test if filed as a follow-up issue: + +1. **No `PlatformWallet::fee_paid` accessor** — every PA case derives the fee from `Σ funded - Σ received - Σ remaining`. A first-class `last_transfer_fee()` (or a `fee` field on `PlatformAddressChangeSet`) would let assertions read the fee directly. Currently noted as a comment in `cases/transfer.rs:142-147`. +2. **No public sync-watermark getter on `PlatformAddressWallet`** — PA-007 needs to read the provider's `last_known_recent_block` to assert monotonicity. The field is internal; exposing a `pub fn sync_watermark() -> Option` would unblock cleanly. +3. **`IdentityManager::known_identities()` shape** — needed by ID-001's "exactly one identity registered" assertion. If the manager exposes only `BTreeMap` without a length convenience, the test must pull internals; a `.len()` / `.identity_ids()` helper would be cleaner. +4. **Token-balance accessor by `(identity, contract, position)`** — `wallet/tokens/wallet.rs:248` already has `balance(...)`; confirm signature matches what TK-001 needs (`balance_for(identity_id, contract_id, position)`) and add the convenience if not. +5. **DPNS `register_name_with_external_signer` lacks a "wait for visibility" partner** — Wave A would benefit from a `wait_for_dpns_name_visible(name, timeout)` helper, ideally co-located with `wait_for_balance` in `framework/wait.rs`. +6. **No protocol-version accessor for `min_input_amount` / `max_outputs`** — PA-009 and PA-014 need to read these from the active `PlatformVersion`; expose a thin test-friendly getter. + +--- + +## 5. Out-of-scope register + +Explicit list of what this suite WILL NOT cover, with reasons. Each entry +prevents future scope creep arguments. + +1. **Shielded transfers** — entire `wallet/shielded/` surface. Reason: prover, viewing-key derivation, and note-selection are a parallel system; coverage belongs in a dedicated suite. Re-evaluate when shielded ships to mainnet. +2. **Credit withdrawals** (`wallet/identity/network/withdrawal.rs`, `wallet/platform_addresses/withdrawal.rs`) — withdrawal verification requires Layer-1 observation of the withdrawal tx. Blocked on Task #15 (SPV stabilisation). Defer. +3. **Token contract deployment** — no testnet contract registry; the suite assumes pre-deployed contracts via env config (Wave D). +4. **Asset-lock-funded identity registration** — the bank holds Platform credits, not Core UTXOs. The address-funded variant (ID-001) covers this need from the wallet's perspective; full asset-lock coverage stays with DET (`dash-evo-tool/tests/backend-e2e/identity_create.rs`). +5. **DAPI Core path** (`tx_is_ours`, mn-list diffs, peer behaviour) — DET territory; this suite tests the wallet against DAPI, not DAPI itself. +6. **Cross-process bank concurrency** — README §"Multi-process safety" documents the operator-side requirement; not a test concern. +7. **Mainnet runs** — config supports `network=mainnet` but the suite's bank-funded model is testnet-by-policy. Mainnet runs require an explicit operator review; out-of-scope for automation. +8. **CN-002 (masternode voting)** — needs a regtest-with-masternodes harness that doesn't exist today. +9. **Non-BIP-39 mnemonic / seed sources** — see §1.2. Mnemonics must be drawn from the BIP-39 English wordlist; raw-entropy and arbitrary-UTF-8 paths are out of scope. +10. **Clock-skew / wall-clock-dependent assertions** — testnet runners are assumed to have NTP. Tests that rely on chain timestamps assume the runner's wall clock is within a few seconds of chain time. Cases that need to assert behaviour under arbitrary skew belong in a unit-test layer below this suite. + +--- + +## 6. Open questions for product owner + +Each question's answer changes the spec; numbered for reference. + +1. **Token contract registry** — do we maintain one canonical testnet token contract for TK-001..TK-004, or do we rely on operators to provide their own via env? (Answer changes Wave D scope.) +2. **Contested-name coverage** — should CN-001 be promoted to P1, or do we accept DET parity and leave it P2/deferred? +3. **Long-running tests** — PA-005 (16 funding round-trips, ~3 min) is borderline. Do we accept multi-minute tests in the default `cargo test --test e2e` run, or gate them behind a `slow-tests` cargo feature? +4. **Identity withdrawal coverage** — once SPV (Task #15) lands, do we want withdrawal coverage here, or is that DET's exclusive territory? +5. **Mainnet smoke** — should the suite ever support a single, opt-in mainnet smoke case (e.g. PA-001 with a tiny `1_000`-credit transfer) for release-gate validation? +6. **Fee-bound numbers** — PA-003 asserts `fee_5 - fee_1 < 1_000_000`. Should we baseline empirical fee numbers and tighten these bounds in a follow-up, or keep them loose and rely on protocol-version bumps to reset them? +7. **Deterministic fixture network** — testnet is shared and noisy. Is there appetite to maintain a regtest-with-Drive cluster for CI exclusively, or do we accept testnet flakiness as the operating constraint? +8. **Test DAPI proxy infra** — PA-013 and the broadcast-retry contract require a controllable test DAPI proxy. Build it bespoke (`httpmock`-based), reuse an existing harness from elsewhere in the workspace, or defer the case until the proxy lands? +9. **Cancellation-hook plumbing** — Harness-G4 needs a test-only injection point between broadcast and proof-fetch. Acceptable to add a `cfg(test)` hook on the wallet, or must this stay external (wrap the future in a `select!` from the test side and accept coarser cancellation granularity)? + +--- + +Catalogued by Marvin (QA), with the resigned competence of someone who has read every line of this code twice. Edge-case expansion by Trillian, who knows that the difference between "tested" and "tested at the boundary" is the difference between "ships" and "ships back". diff --git a/packages/rs-platform-wallet/tests/e2e/framework/cleanup.rs b/packages/rs-platform-wallet/tests/e2e/framework/cleanup.rs index c5eb33fced7..68fe7d04612 100644 --- a/packages/rs-platform-wallet/tests/e2e/framework/cleanup.rs +++ b/packages/rs-platform-wallet/tests/e2e/framework/cleanup.rs @@ -11,6 +11,7 @@ use std::time::Duration; use dpp::address_funds::{AddressFundsFeeStrategyStep, PlatformAddress}; use dpp::fee::Credits; use dpp::identity::signer::Signer; +use dpp::state_transition::address_funds_transfer_transition::AddressFundsTransferTransition; use dpp::version::PlatformVersion; use key_wallet::wallet::initialization::WalletAccountCreationOptions; use key_wallet::Network; @@ -202,10 +203,17 @@ fn wallet_err(err: PlatformWalletError) -> FrameworkError { FrameworkError::Wallet(err.to_string()) } -/// Drain every owned platform address back to `bank_addr` in a single -/// transition.

Adds dedicated `Sdk(String)` / `Spv(String)` variants to `FrameworkError` and routes `SdkBuilder::build` / `TrustedHttpContextProvider` / DAPI parse / SPV storage / mn-list-sync failures through them so the underlying error string survives instead of being swallowed by `NotImplemented(&'static str)`. Plumbs the slot-locked workdir into `spv::start_spv` / `build_client_config` so the deferred SPV runtime tracks the cross-process slot lock instead of sharing `/spv-data`. Reorders `Registry` mutators (insert / remove / set_status) to persist the JSON snapshot before swapping into `self.state` — a failed write now leaves both memory and disk on the prior state, restoring the module's "persist before returning" contract.

A spec entry that describes a non-existent parameter erodes that trust. Filing the drift as Found-020 (and surfacing it via the PA-001b status field) makes the gap visible without forcing an immediate spec rewrite — the resolution can wait for a coordinated PA-001b implementation pass. + --- ## 4.
