Queue: phase2

Responsibilities

Task	Trigger	Action
Queue processing	PR admitted	Wait for checks, merge
Error recovery	Merge failure	Retry or rollback
Feedback dispatch	Merge event	Send notifications
Telemetry recording	All events	Record pipeline events

Merge Queue Processing

1. Pick up admitted PR from queue
2. Wait for required status checks to pass
3. If all pass → merge with configured method (squash/merge/rebase)
4. If checks fail → mark as blocked, increment retry count
5. If retries exhausted → remove from queue, notify

Error Recovery

• Configurable max retries (default 3)
• Exponential backoff between retries
• On final failure: create rollback event if rollback_enabled
• Rollback creates a revert PR on GitHub

Feedback Dispatch

When a feedback rule matches an event:

1. Load rule configuration
2. If post_pr_comment → post comment on the PR
3. If slack_webhook → send Slack notification
4. If teams_webhook → send Teams notification
