18-23: Document the override values.The eventBlockRange and eventBlockRangePerCron are reduced from 5000 to 100 and 200 respectively for EVMX_CHAIN_ID. Add a comment explaining why these specific values are chosen (e.g., chain characteristics, performance requirements, testing constraints).

12-12: LGTM on version bump.Standard patch version increment from 1.1.37 to 1.1.39.
36-36: LGTM on @types/pg addition.The types package correctly supports the existing
pgdevDependency at line 48.
57-59: Remove unused uuid dependency. No import or require usage found; if it's not referenced elsewhere (e.g., tests, scripts), remove it from package.json to avoid unnecessary bloat.hardhat-scripts/s3Config/buildConfig.ts (1)
58-58: LGTM on override application.The spread operator correctly merges chain-specific overrides after defaults, allowing per-chain customization of eventBlockRange and eventBlockRangePerCron values.

Critical race condition on async state.
This function calls incrementCounters (an async function) multiple times in a loop without awaiting completion. Each iteration overwrites:
onCompleteData(line 64 inincrementCounters)incrementedflag (line 58 inincrementCounters)
This causes nondeterministic behavior where only the last callback is registered, and intermediate async operations may not complete as expected.
This should either:
- Add the
asyncmodifier and use proper sequencing/batching - Document that only the final iteration's callback is intentional
- Redesign to track completion of all batched operations
Additionally, the count parameter is unbounded, creating a gas DoS vector.
Apply this diff to add validation:
function incrementCountersMultiple(address[] memory instances_, uint256 count) public {
+ require(count > 0 && count <= 100, "Invalid count");
for (uint256 i = 0; i < count; i++) {
incrementCounters(instances_);
}

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In test/apps/app-gateways/counter/CounterAppGateway.sol around lines 67–71, the
loop calling incrementCounters repeatedly creates a race where onCompleteData
and the incremented flag are overwritten by concurrent async callbacks; fix by
making the function sequence or aggregate operations instead of fire-and-forget:
either add an async modifier and await each incrementCounters call (or refactor
incrementCounters to accept a batch/count and process all items internally), or
change incrementCounters to return a per-call completion token and track
completion for each token so callbacks don’t clobber shared state; additionally
add input validation to prevent unbounded loops by introducing a MAX_BATCH
constant and require(count > 0 && count <= MAX_BATCH) at the start of the
function.
