Caution Review failedPull request was closed or merged during review 📝 WalkthroughWalkthroughAdds and adjusts unit tests across multiple v0 platform_events modules: several modules gain new tests (checkpointing, quorum selection, protocol upgrade, state-transition cleanup and decoding), while tests were removed from two core_chain_lock modules (make_sure_core_is_synced_to_chain_lock and verify_chain_lock_through_core). No production code or public API signatures changed. Changes

make_sure_core_is_synced_to_chain_lock_v0 (or the exported function that returns
CoreSyncStatus) using a TestPlatformBuilder-created platform with a
MockCoreRPCLike wired in, set expectations on
MockCoreRPCLike::expect_submit_chain_lock (or submit_chain_lock) to return the
desired heights, call the actual function with make_chain_lock inputs, and
assert the returned CoreSyncStatus variants (Done/Almost/Not) to validate RPC
integration and real branching; ensure you cover cases where best >= given, best
< given but within recent_block_count, and best < given beyond
recent_block_count.

instead of exercising the code under test; replace direct calls to
mock_rpc.verify_chain_lock and mock_rpc.submit_chain_lock with calls to the
method under test (verify_chain_lock_through_core_v0) on the Platform or module
function that accepts the core RPC mock, passing the same chain_lock and submit
flag, and assert the returned (bool, Option<CoreSyncStatus>) tuple for both
submit and non-submit paths; remove the unused Platform instantiation if you
instead call the free function, or inject/mock the core RPC into Platform so you
call platform.verify_chain_lock_through_core_v0(...) and validate its returned
bool and CoreSyncStatus mapping instead of only asserting mock return values.

test_transition_to_version_12_creates_shielded_pool_trees should assert the
actual side effects instead of only checking is_ok(): after calling
platform.transition_to_version_12(&transaction, platform_version) assert that
the expected shielded pool trees exist (use the Drive/Grove API used elsewhere
in this module to query for the specific tree roots/nodes created by
transition_to_version_12) and that no unexpected version transitions occurred
beyond 11 and 12 (e.g., verify the set of created/updated tree keys or version
flags in the store reflects only the changes from transition_to_version_11 and
transition_to_version_12); apply the same change to the sibling test around
lines 807-833 or alternatively rename the tests to match their current weaker
assertions if you do not want to assert side effects.

Audit Review
This PR has a split personality. The decode_raw_state_transitions, should_checkpoint, protocol upgrade, and cleanup/store tests are legitimate and call production code. However, all 6 tests in the core_chain_lock directory are fake — they test mock wiring or inline arithmetic instead of calling production functions. Both auditors flagged this independently.
Good tests
decode_raw_state_transitions— calls production code, tests edge cases, specific error variant matchingshould_checkpoint— genuinely callsshould_checkpoint_v0with real platform state- Protocol upgrade transitions — call production functions,
test_transition_to_version_11_creates_address_treesverifies GroveDB state - Cleanup/store smoke tests — simple but valid
Production bug discovered (pre-existing, not introduced by this PR)
Both make_sure_core_is_synced_to_chain_lock/v0 (line 26) and verify_chain_lock_through_core/v0 (line 28) contain best_chain_locked_height - given_chain_lock_height in a branch only reached when best < given. Since these are u32, the subtraction wraps to ~4 billion, making CoreSyncStatus::Almost unreachable dead code. The fix is to reverse operands: given_chain_lock_height - best_chain_locked_height. The test comment in test_core_sync_status_variants identifies this but provides no protection since the test is fake.
…ition The test_decode_state_transition_at_exact_max_size test was panicking because all-zeros at max size CAN decode as a valid state transition. The test should verify the size check didn't reject it (no StateTransitionMaxSizeExceededError), not that decoding must fail. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Code Review
Test-only PR adding 30 tests across 9 files. The decode_raw_state_transitions and should_checkpoint tests are well-constructed and exercise real production code. However, two entire test files (6 tests total) in the core_chain_lock modules are completely vacuous — they never call the production functions they claim to test, instead testing inline reimplementations or mock objects directly. Several protocol-upgrade tests have weak assertions (is_ok() only) that would pass even if the transitions silently did nothing.

In `packages/rs-drive-abci/src/execution/platform_events/core_chain_lock/make_sure_core_is_synced_to_chain_lock/v0/mod.rs`:
- [BLOCKING] lines 57-93: test_core_synced_returns_done is a tautology — never calls the production function
This test constructs a mock RPC and a platform but never calls `make_sure_core_is_synced_to_chain_lock_v0`. Lines 85-92 evaluate `if 100u32 >= chain_lock.block_height { CoreSyncStatus::Done } else { CoreSyncStatus::Not }` inline and assert it matches `Done`. This is asserting that `100 >= 100` is true. The mock expectation on `submit_chain_lock` (line 63-65) is never exercised. This test would pass even if the production function were deleted.
- [BLOCKING] lines 95-121: test_core_sync_status_variants reimplements production logic locally instead of testing it
This test manually reproduces the subtraction and comparison logic from the production function using local variables and `wrapping_sub`, then asserts properties of its own inline code. It never calls `make_sure_core_is_synced_to_chain_lock_v0`. The comments in the test even identify the unsigned subtraction issue (line 113: "This is actually a potential bug") but the test doesn't validate the production function's behavior around it.
In `packages/rs-drive-abci/src/execution/platform_events/core_chain_lock/verify_chain_lock_through_core/v0/mod.rs`:
- [BLOCKING] lines 62-117: All four verify_chain_lock tests call mock RPC methods directly, bypassing the production wrapper entirely
The production function under test is `verify_chain_lock_through_core_v0` (lines 16-42), which contains the `submit` branching logic and `CoreSyncStatus` mapping. None of the four tests call it. Instead:
- `test_verify_without_submit_delegates_to_verify_chain_lock` (line 80): calls `mock_rpc.verify_chain_lock()` directly
- `test_verify_without_submit_returns_false_for_invalid` (line 91): same
- `test_submit_chain_lock_returns_synced_when_best_height_matches` (line 104): calls `mock_rpc.submit_chain_lock()` directly
- `test_submit_chain_lock_returns_higher_height` (line 115): same
These tests verify that mockall mocks return what you tell them to return. They provide zero coverage of the production wrapper.
In `packages/rs-drive-abci/src/execution/platform_events/protocol_upgrade/perform_events_on_first_block_of_protocol_change/v0/mod.rs`:
- [SUGGESTION] lines 785-801: test_transition_to_version_12_creates_shielded_pool_trees only asserts is_ok(), doesn't verify trees exist
The test calls the production function `transition_to_version_12` (good), but only asserts `result.is_ok()`. Compare with `test_transition_to_version_11_creates_address_trees` (lines 756-782) which actually queries GroveDB to verify the `AddressBalances` root tree was created. This test should similarly verify at least one of the shielded pool trees (e.g., the sum tree at `SHIELDED_CREDIT_POOL_KEY_U8`) actually exists after the transition.
- [SUGGESTION] lines 743-750: test_transition_to_version_6 fetches contract but doesn't verify it was found
Lines 743-750 call `get_contract_with_fetch_info_and_fee` and assert `fetched.is_ok()`. The `Ok` variant wraps an `Option` — the contract info could be `None` and the test would still pass. The assertion should unwrap the Ok and verify the contract info is `Some`.
- [SUGGESTION] lines 807-833: test_transition_from_version_10_only_does_11_and_12 doesn't verify which transitions ran
The test name claims it verifies that only transitions 11 and 12 fire when upgrading from version 10, but the sole assertion is `result.is_ok()`. Since `set_genesis_state()` creates the full latest-version state, the version-4/6/8/9 branches are no-ops anyway (their trees already exist via `insert_if_not_exists`). The test would pass even if the dispatch conditions were completely removed.
In `packages/rs-drive-abci/src/execution/platform_events/state_transition_processing/decode_raw_state_transitions/v0/mod.rs`:
- [SUGGESTION] lines 243-269: Boundary test doesn't distinguish 'rejected as oversized' from 'failed deserialization'
The test creates data at exactly `max_size` bytes and verifies it's not `SuccessfullyDecoded`, accepting either `InvalidEncoding` or `FailedToDecode`. However, the oversized rejection branch also produces `InvalidEncoding` (with `StateTransitionMaxSizeExceededError`). If someone changed the size check from `>` to `>=`, this test would still pass because it doesn't check that the error is specifically a deserialization error rather than a size-exceeded error.
