Context
IMAP-based GitHub notification ingestion is practical, but it depends on email formatting, mailbox UID state, auth headers, and delivery timing. GitHub webhooks provide signed, structured delivery ids and richer event context.
Proposal
Design and optionally implement a GitHub App/webhook ingestion path, keeping IMAP as fallback or compatibility mode.
Acceptance criteria
- Short design note compares webhook ingestion vs IMAP for trust, idempotency, latency, operational burden, and rollout.
- Event ids/delivery ids map cleanly to queue idempotency.
- Webhook signature verification is mandatory.
- IMAP remains supported during migration.
Priority
Medium.
