🧹 Nitpick comments (25)
swift-dash-core-sdk/Package.swift (2)
24-27: Documented target removal looks good; add a short deprecation note in README for downstreams.The manifest comments are clear. Consider a brief deprecation note in the package’s README pointing integrators to the unified SDK path (dashpay-ios) to avoid confusion for teams pinning older revisions.
I can draft a short README snippet/changelog entry if helpful.
31-33: Confirm StrictConcurrency flag compatibility; consider aligning tests and future-proofing.Using
.enableExperimentalFeature("StrictConcurrency")is fine if your CI/Xcode toolchain (Swift 5.9) supports it. Two follow-ups:
- Apply the same setting to the test target to avoid differing concurrency diagnostics between library and tests.
- If your toolchain supports it, prefer
.enableUpcomingFeature("StrictConcurrency")(as some toolchains deprecate the experimental spelling). Keep whichever your CI accepts.Proposed diffs:
Option A: keep experimental flag, propagate to tests
.testTarget( name: "SwiftDashCoreSDKTests", dependencies: ["SwiftDashCoreSDK"], - path: "Tests/SwiftDashCoreSDKTests" + path: "Tests/SwiftDashCoreSDKTests", + swiftSettings: [ + .enableExperimentalFeature("StrictConcurrency") + ] ),Option B: switch to upcoming feature and propagate to tests
.target( name: "SwiftDashCoreSDK", dependencies: [], path: "Sources/SwiftDashCoreSDK", swiftSettings: [ - .enableExperimentalFeature("StrictConcurrency") + .enableUpcomingFeature("StrictConcurrency") ] ), .testTarget( name: "SwiftDashCoreSDKTests", dependencies: ["SwiftDashCoreSDK"], - path: "Tests/SwiftDashCoreSDKTests" + path: "Tests/SwiftDashCoreSDKTests", + swiftSettings: [ + .enableUpcomingFeature("StrictConcurrency") + ] ),If the alternative spelling isn’t recognized by your current toolchain, keep the existing one.
To verify which spelling your CI supports, try a quick dry run locally or in CI. If you want, I can add a minimal matrix job that compiles the package with both settings to auto-select the supported one.
test-utils/src/fixtures.rs (3)
103-111: Simplify expected hash construction using parse()You can avoid manual hex decoding and byte reversal by parsing the canonical hex directly into BlockHash. This reduces duplication and the chance of mirrored mistakes between code-under-test and expected values.
Apply this diff:
- // Create expected BlockHash instances from the constants for proper comparison - let expected_mainnet = { - let bytes = decode(MAINNET_GENESIS_HASH).unwrap(); - let mut reversed = [0u8; 32]; - reversed.copy_from_slice(&bytes); - reversed.reverse(); - BlockHash::from_slice(&reversed).unwrap() - }; + // Parse expected BlockHash instances from the canonical hex (display) form + let expected_mainnet: BlockHash = MAINNET_GENESIS_HASH.parse().unwrap();
112-118: Ditto for testnet: use parse() instead of manual reverseKeeps the test short, expressive, and independent from the implementation details of the fixture helpers.
Apply this diff:
- let expected_testnet = { - let bytes = decode(TESTNET_GENESIS_HASH).unwrap(); - let mut reversed = [0u8; 32]; - reversed.copy_from_slice(&bytes); - reversed.reverse(); - BlockHash::from_slice(&reversed).unwrap() - }; + let expected_testnet: BlockHash = TESTNET_GENESIS_HASH.parse().unwrap();
120-121: Optional: also assert the display (hex) formAsserting the hex formatting matches the canonical constants guards against endianness regressions in Display/LowerHex implementations.
Apply this diff:
assert_eq!(mainnet, expected_mainnet); assert_eq!(testnet, expected_testnet); + // Additionally ensure the human-readable hex form matches the canonical constants + assert_eq!(format!("{:x}", mainnet), MAINNET_GENESIS_HASH); + assert_eq!(format!("{:x}", testnet), TESTNET_GENESIS_HASH);test_smart_algo.sh (1)
7-12: Confirm CLI flag and verify smart-algo window coverage
The CLI parser in dash-spv/src/main.rs (lines 114–115) defines and exposes
--start-height.Manually run the smart-algo script and inspect the debug log to ensure the smart algorithm is triggered over heights 1260302–1290302 when starting from 1,100,000 (without relying on checkpoint hashes).
For CI/scripts robustness, prepend your test script with:
set -euo pipefaildash-spv/src/network/message_handler.rs (1)
95-100: Preserving GetQRInfo payload in Unhandled is correct (LGTM).The arm now returns Unhandled(NetworkMessage::GetQRInfo(req)), keeping the original payload intact for upper layers or test harnesses.
If inbound GetQRInfo requests are common in testnets, consider tracking a dedicated counter (e.g., getqrinfo_request_messages) instead of incrementing other_messages for better observability.
qr_info_spv_plan/PHASE_1.md (1)
340-345: Rename in StorageManager snippet conflicts with earlier examplesYou’ve documented
get_header_height_by_hash(&BlockHash)here, but earlier “Create block height fetcher” examples still callstorage.get_header_height(block_hash)andself.storage.get_header_height(block_hash).await. This inconsistency will confuse implementers and readers.
- Align all earlier snippets to use
get_header_height_by_hash.- Also, state clearly that the method name was renamed (and that call sites must update), rather than “NO NEW METHODS NEEDED”.
Would you like me to sweep the doc and update all occurrences of
get_header_height(...)toget_header_height_by_hash(...)for consistency?dash-spv/src/sync/sequential/phases.rs (2)
549-565: Good gating on QRInfo progress to prevent overshootThe guard
if *qr_info_completed < *qr_info_requestsand clampingrequests_completedvia.min(*requests_total)resolves overshoot and duplicate-accounting issues. Updatinglast_progressonly on actual increments is also correct.Consider adding a trace log when a duplicate completion is ignored to aid diagnostics:
if *qr_info_completed < *qr_info_requests { *qr_info_completed += 1; *requests_completed = (*requests_completed + 1).min(*requests_total); *last_progress = Instant::now(); +} else { + tracing::trace!("Ignoring duplicate QRInfo completion (completed={} of {})", + qr_info_completed, qr_info_requests); }
573-591: MnListDiff gating mirrors QRInfo fix; back-compat counter retainedSame positive notes as above. Retaining
*diffs_processed += 1preserves prior metrics while keeping the new request-based progress sane.Add a trace for ignored duplicates (see the QRInfo comment) for parity and easier debugging.
dash-spv/src/sync/sequential/mod.rs (1)
1821-1825: Per-block MnListDiff requests: confirm rate-limiting and backpressureRequesting a diff for each new block keeps a rolling validation window, but can be chatty. Ensure the request controller enforces per-peer limits and retries so we don’t overload peers during bursts.
If bursts are common, consider batching or coalescing adjacent requests (e.g., only request for the latest tip if prior ones are still in flight).
dash/src/sml/llmq_type/network.rs (2)
108-118: Per-window activation gating is a solid improvementSkipping per-window based on
window.mining_startinstead of blanket type-level skipping enables post-activation windows while correctly excluding pre-activation ones. Logging at trace is appropriate.Consider promoting the skip decision to debug level temporarily while validating on testnet/mainnet to help spot misconfigurations in the field.
135-142: Avoid magic activation heights; centralize as constantsThe hardcoded activation heights are opaque. Define constants (or place them in a config/params module) and reference them here to improve discoverability and maintenance.
Apply this refactor pattern:
impl Network { const MAINNET_PLATFORM_ACTIVATION: u32 = 1_888_888; const TESTNET_PLATFORM_ACTIVATION: u32 = 1_289_520; } fn should_skip_quorum_type(&self, llmq_type: &LLMQType, height: u32) -> bool { match (self, llmq_type) { (Network::Dash, LLMQType::Llmqtype100_67) => height < Self::MAINNET_PLATFORM_ACTIVATION, (Network::Testnet, LLMQType::Llmqtype25_67) => height < Self::TESTNET_PLATFORM_ACTIVATION, _ => false, } }Do any other LLMQ types on your networks have activation thresholds (e.g., 400_85)? If yes, extend the matcher accordingly.
dash-spv/tests/error_handling_test.rs (1)
205-219: Mocks expanded correctly; consider re-enabling the test module and tightening failure modesThe broadened mock surface aligns with the expanded StorageManager trait and covers read/write failure injections. To get value from this suite:
- Drop the cfg gate once method signatures are aligned and types imported.
- Consider exercising the new “error-injection points” in more paths (e.g., get_headers_batch failures during recovery).
- For methods returning Option, return Some(...) in a couple of spots to simulate realistic non-empty cases (e.g., get_tip_height -> Some(1234), get_header_height_by_hash -> Some(height)) for specific test scenarios.
If you share the target behaviors, I can contribute a set of granular tests that validate error propagation through the new storage paths.

dash-spv/tests/qrinfo_integration_test.rs (1)
127-128: Defaults flip to qr_info_extra_share=false looks right; consider un-ignoring this testThis test has no network or I/O and would be valuable to run in CI. Recommend removing #[ignore] so regressions in defaults are caught early.
dash-spv/tests/chainlock_validation_test.rs (1)
365-365: Redundant storage initialization earlier in the test; prefer a single handleAt Line 365 you obtain a storage handle from the client right after previously creating a DiskStorageManager at Lines 347–349. The earlier handle is never used and is dropped immediately upon shadowing, which is wasteful and potentially confusing.
- Remove the earlier DiskStorageManager creation and rely on client.storage().
- Alternatively, reuse the first handle and avoid calling client.storage() here.
I recommend deleting the earlier creation (Lines 347–349) to keep a single storage source in this test.
dash-spv/src/sync/chainlock_validation.rs (1)
226-257: Usenext_back()to select the most recent quorum entrySince
quorumsis aBTreeMap<QuorumHash, QualifiedQuorumEntry>(ordered by key),iter().next()picks the smallest hash, not the most recent. To deterministically select the last (largest) key, replace:- let (quorum_hash, entry) = quorums.iter().next().ok_or_else(|| { + let (quorum_hash, entry) = quorums.iter().next_back().ok_or_else(|| { SyncError::Validation(format!( "No quorum entries found for LLMQ type {:?}", self.config.required_llmq_type )) })?;Also, this method no longer returns
Ok(None), so you may eventually simplify its signature fromSyncResult<Option<…>>toSyncResult<(BlockHash, BLSPublicKey)>.
[optional_refactors_recommended]dash-spv/src/sync/validation.rs (3)
236-247: Better error context with resolved heights; watch out for “unknown height” = 0 collisionsResolving block_height from engine.block_container.get_height and bubbling it into InvalidMnListDiff improves diagnostics.
Caveat: unwrap_or(0) conflates unknown heights with genesis (0), which can mislead error reporting for diffs whose heights aren’t yet known. Consider either:
- Emitting a distinct “unknown height” message (don’t coerce to 0), or
- Using a cache key that incorporates block hash when height is unknown (see comment on Lines 281–283).
This is optional, but it avoids subtle cache and logging confusion.
281-283: Cache key collision risk when height is unknownUsing ValidationCacheKey::MasternodeList(block_height) with unwrap_or(0) can cause different diffs with unknown heights to collide under height 0. Two safer options:
- Skip caching when height cannot be resolved.
- Introduce a cache key variant for hash-based addressing (e.g., MasternodeListByHash(BlockHash)) and use it when height is None.
Either avoids false cache hits/misses for unknown heights without impacting the common path.
302-307: Remove unused local variable to keep Clippy quietblock_height is computed but not used here. Drop it until needed to avoid warnings and noise.
- // We can resolve block height from the diff's block hash using the engine's block container - let block_height = engine.block_container.get_height(&diff.block_hash).unwrap_or(0); + // Height resolution available via engine.block_container if neededqr_info_spv_plan/PHASE_3.md (5)
68-84: Priority enum and request spec look good.The priority enum deriving Ord enables sorting; spec fields cover base/tip hash and priority. Consider documenting expected dedup behavior when multiple specs target the same tip.
175-206: Recovery strategy math is sane; consider making thresholds configurable.The failure-rate cutoffs and step-down logic are reasonable. Making thresholds tunable via config would help A/B and network variability without code changes.
420-432: Remove timeouts on successful correlation to avoid growth.Entries are only dropped on timeout. Successful responses leave
request_timeoutsto grow until timeout, increasing memory usage and churn.Quick fix: remove the corresponding entry on success:
- if let Some(sender) = self.pending_requests.remove(&tip_hash) { + if let Some(sender) = self.pending_requests.remove(&tip_hash) { if sender.send(qr_info).is_err() { tracing::warn!("Failed to send QRInfo response - receiver dropped"); } + // remove from timeouts queue + if let Some(pos) = self.request_timeouts.iter().position(|(h, _)| *h == tip_hash) { + self.request_timeouts.remove(pos); + } Ok(())If you adopt
(base, tip)keys, adjust the predicate accordingly.
501-520: Minor grammar/formatting polish in Success Criteria.Nitpicks to improve readability:
- Consider adding a blank line after “## Success Criteria” before “### Integration Requirements.”
- Rephrase checklist items to read as complete statements, e.g.:
- “Maintain existing sequential performance when parallel features are disabled.”
- “Gracefully degrade to sequential on high failure rates.”
These are stylistic; content is clear.
523-543: Risk wording nitpicks.
- “All parallel features behind …” → “All parallel features are behind …”
- “Adaptive concurrency reduction on failures” → “Adaptive concurrency reduction on failures is enabled.”
Purely editorial.

Learning: The `StorageManager` trait in `dash-spv/src/storage/mod.rs` uses `&mut self` methods but is also `Send + Sync`, and implementations often use interior mutability for concurrency. This can be confusing, so explicit documentation should clarify thread-safety expectations and the rationale for the API design.

Learning: Passing exclusive mutable references to network and storage managers into the sync manager in async Rust can lead to borrow checker issues or runtime contention if concurrent access is needed elsewhere. It's advisable to document this architectural tradeoff and consider refactoring to interior mutability or message passing for shared access as the codebase evolves.

410-413: Explicitly ignoring blocks during MnList phase is fine; verify downstream block processing won’t starveThe rationale is clear and the log level is appropriate. Ensure that:
- Blocks requested due to filter matches are still processed by the dedicated block processor path while MnList is running, and
- Ignored blocks here won’t be dropped on the floor (e.g., are queued or re-requested later by the block processor).
If helpful, I can scan the codebase to confirm that block processing in non-DownloadingBlocks phases is indeed handled elsewhere.

remove_utxo signature mismatch with trait; will block re-enabling tests
The StorageManager trait typically returns the removed UTXO: StorageResult<Option<Utxo>>. This impl returns StorageResult<()>, which won’t match the trait when these tests are enabled.
Fix the signature and return value:
- async fn remove_utxo(&mut self, _outpoint: &OutPoint) -> StorageResult<()> {
+ async fn remove_utxo(&mut self, _outpoint: &OutPoint) -> StorageResult<Option<Utxo>> {
if self.fail_on_write {
return Err(StorageError::WriteFailed("Mock write failure".to_string()));
}
- Ok(())

Type import likely needed for UnconfirmedTransaction
This impl references UnconfirmedTransaction but the file doesn’t import it. When you remove the cfg gate and compile this test, it will fail to resolve the type unless it’s brought into scope (or fully qualified in the trait).
Add:
use dash_spv::wallet::UnconfirmedTransaction;right after the other use statements, or fully qualify the type in the signature to match the trait definition exactly.
🤖 Prompt for AI Agents
In dash-spv/tests/error_handling_test.rs around lines 499 to 508, the impl uses
UnconfirmedTransaction but the type is not imported, so compilation will fail
when the cfg gate is removed; fix by adding the missing use statement (use
dash_spv::wallet::UnconfirmedTransaction;) alongside the other use imports near
the top of the test file, or alternatively fully qualify the parameter type in
the function signature to dash_spv::wallet::UnconfirmedTransaction to match the
trait definition.

451-451: Address inner migration to dashcore is a good moveSwitching to dashcore::Address simplifies downstream interop. One small follow-up: in get_network(), a panic via unreachable! on unknown variants is brittle across FFI. Consider a safe fallback (e.g., Testnet) or an error-returning API instead of panicking.
Suggested change for get_network to avoid panics across FFI boundaries:
- unknown => unreachable!("Unhandled network variant: {:?}", unknown), + // Avoid panicking across FFI; default to Testnet to match team preference for fallbacks. + _ => Network::Testnet,
529-597: Replace the commented-out AddressGenerator with minimal helpers for BIP44 P2PKH derivation from xpubRather than keeping a large commented stub, add small, self-contained helpers that derive P2PKH addresses from an account xpub using standard BIP44 paths (change 0/1, index).

Removed the qr_info_spv_plan planning documentation folder as requested. This folder contained phase planning documents that are no longer needed.
Restored the AddressGenerator interface definition that was commented out. This interface is needed for the FFI bindings to work properly.
Reverted all recent changes that replaced kw_address with dashcore types: - Restored 'address as kw_address' import - Reverted AddressType conversions back to kw_address types - Removed extra Error enum match cases (CoinJoinNotEnabled, Serialization, InvalidParameter) - Restored Address struct to use kw_address::Address - Uncommented AddressGenerator struct and all its methods - Restored generate() and generate_range() method implementations This brings the file back to its original working state with proper key-wallet address handling.

94-110: Add assertions to validate vector lengths against the LLMQ size.Small enhancement: assert that signers/valid_members lengths match llmq_type.size() to catch regressions in struct construction.
Consider adding the following assertions after constructing diff (e.g., after Line 118):
let entry = &diff.new_quorums[0]; let expected = entry.llmq_type.size() as usize; assert_eq!(entry.signers.len(), expected, "signers length must equal LLMQ size"); assert_eq!(entry.valid_members.len(), expected, "valid_members length must equal LLMQ size");

109-117: Nit: Make the comment/log message generic (not platform-specific).The skip logic is generic and may apply to more types later. Tweak the comment and message to avoid implying it only targets platform quorums.
Apply this diff:
- // Skip platform quorums before activation if needed + // Skip quorums before activation if needed if self.should_skip_quorum_type(&llmq_type, window.mining_start) { - log::trace!( - "Skipping {:?} for height {} (activation threshold not met)", - llmq_type, - window.mining_start - ); + log::trace!( + "Skipping quorum type {:?} at mining_start {} (activation threshold not met)", + llmq_type, + window.mining_start + ); continue; }dash-spv/src/sync/chainlock_validation.rs (3)
249-254: “Most recent quorum” selection via iter().next() is not deterministicThe comment says “Get the most recent quorum”, but quorums.iter().next() does not guarantee recency:
- For HashMap-like containers, order is arbitrary.
- For BTreeMap keyed by BlockHash, ordering by hash is unrelated to recency.
- For insertion-ordered types, “first” might not be the newest.
Please ensure deterministic selection based on a concrete notion of “recency” (e.g., creation height or quorum index), or verify that the underlying container guarantees “newest-first” iteration.
If the container is ordered and newest is last:
- let (quorum_hash, entry) = quorums.iter().next().ok_or_else(|| { + let (quorum_hash, entry) = quorums.iter().next_back().ok_or_else(|| { SyncError::Validation(format!( "No quorum entries found for LLMQ type {:?}", self.config.required_llmq_type )) })?;If “recency” is captured by a field (example: quorum_entry.quorum_index), select explicitly:
- let (quorum_hash, entry) = quorums.iter().next().ok_or_else(|| { + let (quorum_hash, entry) = quorums + .iter() + .max_by_key(|(_, e)| e.quorum_entry.quorum_index) + .ok_or_else(|| { SyncError::Validation(format!( "No quorum entries found for LLMQ type {:?}", self.config.required_llmq_type )) })?;Follow-up: since None is no longer returned anywhere in this function, consider in a future (breaking) change simplifying the signature to SyncResult<(BlockHash, BLSPublicKey)>.
257-257: Consider avoiding potential move-from-borrow of quorum_public_keyThis returns entry.quorum_entry.quorum_public_key by value. If BLSPublicKey is not Copy, moving out of a borrowed entry won’t compile; if it is Copy, this is fine. If not Copy, ensure Clone is used:
- Ok(Some((*quorum_hash, entry.quorum_entry.quorum_public_key))) + Ok(Some((*quorum_hash, entry.quorum_entry.quorum_public_key.clone())))
43-44: Avoid hardcoding network parameters in defaultsHardcoding LLMQType::Llmqtype400_60 in Default may not fit all networks (testnet/regtest/devnet). It’s good that the field is configurable, but consider deriving the default from the active network/chain params (e.g., via a dedicated constructor like ChainLockValidationConfig::for_network(params)) to align with the “no hardcoded network params” guideline.
I can sketch a for_network(params) constructor that selects the appropriate default LLMQ type per network if you share where chain params are sourced in this crate.

205-219: Optional: factor repeated fail_on_write checks into a helperMany store/clear methods share identical write-failure checks. A small helper would reduce duplication and make future test-surface changes cheaper.
Example:
impl MockStorageManager { fn guard_write(&self) -> StorageResult<()> { if self.lock_poisoned { return Err(StorageError::LockPoisoned("Mock lock poisoned".into())); } if self.permission_denied { return Err(StorageError::WriteFailed("Permission denied".into())); } if self.disk_full { return Err(StorageError::WriteFailed("No space left on device".into())); } if self.fail_on_write { return Err(StorageError::WriteFailed("Mock write failure".into())); } Ok(()) } }Then invoke
self.guard_write()?;at the top of each write path.Also applies to: 248-254, 309-315, 323-328, 337-342, 406-411, 427-436, 449-458, 478-487, 536-541, 550-555

Learning: The `StorageManager` trait in `dash-spv/src/storage/mod.rs` uses `&mut self` methods but is also `Send + Sync`, and implementations often use interior mutability for concurrency. This can be confusing, so explicit documentation should clarify thread-safety expectations and the rationale for the API design.

94-110: Dynamic quorum sizing via llmq_type.size() is correct and future-proof.Switching signers/valid_members to derive their length from llmq_type.size() removes the previous hardcoded assumption and aligns the test with parameterized LLMQ sizes. Nice improvement.
dash/src/sml/llmq_type/network.rs (1)
109-117: Per-window activation gating is correct and aligns with the new API.Evaluating should_skip_quorum_type per window using window.mining_start prevents pre-activation windows from leaking in while allowing post-activation windows. Good move.

226-238: Good move: explicit Validation errors instead of silent None pathsSwitching to SyncError::Validation for missing masternode lists and list retrieval makes failure modes actionable and surfaces root causes early. This aligns with the PR’s error-handling goals.
241-247: Clear errors when no quorums exist for the required LLMQ typeReturning descriptive SyncError::Validation messages here is a solid improvement over Ok(None), helping operators diagnose configuration/data gaps quickly.

Verify: get_tip_height may be obsolete (trait likely replaced with get_filter_tip_height)
The enriched summary notes get_tip_height was replaced by get_filter_tip_height. If the trait no longer contains get_tip_height, this impl won’t compile. Please confirm the StorageManager trait’s current surface and remove/rename accordingly.

Remove obsolete get_tip_height from MockStorageManager
The current StorageManager trait in dash-spv/src/storage/mod.rs no longer declares get_tip_height (or get_filter_tip_height). As a result, the MockStorageManager impl in dash-spv/tests/error_handling_test.rs defines an extra method that won’t match the trait. Please update this impl to mirror the trait’s actual tip‐height API or remove it if it’s no longer needed.
• dash-spv/tests/error_handling_test.rs (lines 241–246):
- async fn get_tip_height(&self) -> StorageResult<Option<u32>> {
- if self.fail_on_read {
- return Err(StorageError::ReadFailed("Mock read failure".to_string()));
- }
- Ok(Some(0))
- }– Remove or rename this block to the correct method signature as defined in dash-spv/src/storage/mod.rs.
– Verify the trait’s current tip‐height method name and return type before implementing.

MockStorageManager impl defines a now-obsolete get_tip_height method that no
longer matches the StorageManager trait; remove this method or replace it with
the exact tip-height API declared in dash-spv/src/storage/mod.rs (confirm the
current method name and signature there — e.g., get_filter_tip_height or other
name and its return type), then implement the correct method signature with
matching return type and error handling or delete the mock method entirely if

175-177: FFIChainState doesn’t expose checkpoint sync fields
The FFI struct and itsFrom<ChainState>impl only map:
- header_height
- filter_header_height
- masternode_height
- last_chainlock_height
- last_chainlock_hash
- current_filter_tip
The new
ChainStatefieldssync_base_heightandsynced_from_checkpointare never exposed over FFI.
If you intend to surface checkpoint sync state through the FFI API:
- Add
sync_base_height: u32andsynced_from_checkpoint: booltoFFIChainState- Populate them in
impl From<ChainState> for FFIChainState- Add assertions in
test_type_conversions.rsfor those fieldsOtherwise, document in
FFIChainState(and itsFromimpl) that checkpoint-sync fields are intentionally omitted.

SpvStats new fields are not validated in FFISpvStats
connected_peers/total_peers/header_height/filter_height are set in the Rust struct but not asserted post-conversion. Either add FFISpvStats assertions (if supported) or note they’re intentionally ignored.
Try locating these fields in the FFI:

Add missing FFISpvStats assertions for peer and height fields
The SpvStats conversion test in dash-spv-ffi/tests/unit/test_type_conversions.rs currently checks most metrics but omits the four new fields (connected_peers, total_peers, header_height, filter_height). Please update the test to include assertions for these fields:

}This ensures all fields introduced on the Rust side are properly round-tripped to the FFI struct.

SpvStats round-trip test is missing assertions for the four new fields

defaults unknown/None address types to P2PKH which can mislead callers; change
the implementation to return AddressType::Unknown when self.inner.address_type()
is None or unrecognized instead of defaulting to P2PKH — e.g. match or map the
Option from address_type() and convert the present KwAddressType into
AddressType, otherwise return AddressType::Unknown (ensure the conversion path
supports the Unknown variant).

Learning: The `StorageManager` trait in `dash-spv/src/storage/mod.rs` uses `&mut self` methods but is also `Send + Sync`, and implementations often use interior mutability for concurrency. This can be confusing, so explicit documentation should clarify thread-safety expectations and the rationale for the API design.

248-254: Filter header/load/tip mock behavior looks soundRead/write error injection is consistent and the stubs are fine for tests that only care about error paths.
Also applies to: 255-261, 262-267, 269-274
357-365: Header index/batch stubs align with MemoryStorage semanticsReturning
Noneandvec![]while honoring read failures matches expectations for error-path tests.Also applies to: 367-376
406-447: Sync-state and checkpoint mocks: good coverage of error pathsWrite/read error injection is consistent across store/load/clear and ranged getters. No issues spotted.
449-476: Chain/instant lock mocks look correctAPIs are stubbed coherently and honor read/write failure flags. LGTM.
Also applies to: 478-498
499-534: Mempool transaction/state mocks align with earlier feedbackWith
UnconfirmedTransactionnow in scope, these look build-ready once the cfg gate is dropped.Also applies to: 536-555
1147-1184: Concurrency test exercises read/write error paths under contention—nice coverageUsing RwLock with mixed read/write operations ensures both error modes are hit. Cleanly structured.
385-390: No signature mismatch: mock and trait both useStorageResult<()>
TheStorageManager::remove_utxomethod indash-spv/src/storage/mod.rsis declared asasync fn remove_utxo(&mut self, outpoint: &OutPoint) -> StorageResult<()>;which exactly matches the mock in
dash-spv/tests/error_handling_test.rs. No changes are required.
392-397: Trait signature matches mock implementation
The mock’sget_utxos_for_address(&self, _address: &Address) -> StorageResult<Vec<Utxo>>exactly matches the trait declaration indash-spv/src/storage/mod.rs:187. No changes needed.
241-246: Verify trait surface
I wasn’t able to locate the trait declaration automatically—please confirm that the trait your mock implements (e.g. in dash-spv/src/storage/mod.rs or wherever it’s declared) includes both of these methods:
- fn get_tip_height(&self) → StorageResult<Option>;
- fn get_filter_tip_height(&self) → StorageResult<Option>;
That way, when the cfg gate is removed the mock impl will still match the trait.
