Walkthrough

The changes in this pull request focus on the filters package within the api.go file, specifically enhancing the handling of log filtering and subscription management in the subscribeEvents method. The modifications involve the introduction of local variable declarations for the logs variable, ensuring that filtered logs are processed correctly without affecting the outer scope. The overall structure and logic of the method remain unchanged, with no new functionalities introduced, but improvements are made for clarity and maintainability.

Poem

In the code where filters play,
A rabbit hops and clears the way.
With logs anew, scoped tight and neat,
Clarity blooms, a coding treat!
Hooray for changes, let’s all cheer,
For cleaner code is what we hold dear! 🐇✨

122-126: LGTM! The changes correctly prevent log overriding.

The implementation now properly scopes filtered logs to local variables, preventing unintended modifications to the original logs. This ensures that each filter and subscription receives its own independent copy of the filtered logs.

While this approach may use slightly more memory due to creating separate copies for each filter/subscription, it's the correct trade-off for maintaining data integrity and preventing race conditions.

Consider adding a comment explaining the importance of using local variables here to prevent log overriding, which would help future maintainers understand the design decision.
