💡 What:
Replaced the "check then act" pattern in remove_participant_from_room with a direct call to lk_api.room.remove_participant(). Instead of calling list_participants (which makes a network call) and iterating over the list to find the participant, we now directly attempt removal and gracefully catch the resulting exception if the participant doesn't exist. The error level for missing participants was also appropriately reduced from error to warning.

🎯 Why:
The previous code executed a redundant network call and an O(N) loop to verify a participant's existence before acting. Following the Pythonic "Easier to Ask for Forgiveness than Permission" (EAFP) principle saves latency by eliminating the initial read operation.

📊 Impact:

  • Network Requests: Cut network latency in half during the transfer process (1 request vs 2).
  • Compute: Removes an O(N) loop iterating over all participants in a room.

🔬 Measurement:

  • Verified by passing the entire backend test suite (python -m pytest backend/).
  • Verified code compiles successfully via pnpm lint and pnpm build.
  • Added a journal entry detailing the learning regarding SDK network patterns.

… check

Replaced the "check then act" pattern in `remove_participant_from_room`
with a direct `remove_participant` call. This removes the need for
an O(N) local loop and an unnecessary network roundtrip to fetch all
participants when attempting to complete a transfer. Exceptions
for missing participants are caught and gracefully logged.
