decision(firestore-send-email): kit/extension parity – kit continues after an Eventarc publish failure, the extension aborts #3326

firestore-send-email kit/extension parity. Priority: low. The kit is intentionally more robust here; this needs recording, not fixing.

Difference

• Extension: eventChannel.publish() is awaited with no try/catch, and processQueue publishes onStart before it processes the document. If that publish fails, the function fails and the mail is never sent.
• Kit: publish failures are caught and logged as WARN (Failed to publish Eventarc event <type>), and delivery carries on.

Reproduced

Seen in the code, not tested live.

Code

• Extension: onStart publish at index.ts#L364, before processWrite.
• Kit: events.ts#L37-L45.

Resolution

Keep the kit's behaviour, and list it under the README's differences from the extension, as the firestore-bigquery-export kit README does (#3322).
