Critical latency regression on checkout-edge: Wall Time P99 is 18× baseline, sustained since 2:02 AM, and checkout requests are queuing. I'm investigating.

probably the Hyperdrive change in tonight's deploy?

Working on it

  • ✓ Pulled the last 30 minutes of checkout-edge metrics
  • ✓ Correlated with the change records
  • ◐ Testing the Hyperdrive pool hypothesis
  • ○ Draft the fix

You're right. Deploy 9f3c2a1 shrank the hd-prod connection pool from 50 to 5, and checkout requests queue behind connections. Confirmed against the pool metrics and the change record. Fix is drafted, coreplane/checkout-edge#142 restores the pool. CI is running; I'll report back here.

The same agent as the console. Same context graph, same telemetry, same receipts.

  • Mention it anywhere

    @Polylane in a channel or a DM. Replies stream into the thread with a live checklist of what it's doing, and replying continues the same conversation.

  • It chimes in when it can help

    On by default and deliberately shy: a gate decides whether it genuinely has something to add, rate-limited per channel and per hour. Turn it off with /nominal unwatch, or just ask it to stop.

  • Every channel gets house rules

    Standing instructions per channel: answer as this team's on-call helper, keep replies brief, link the runbooks. Anyone in the channel can set them.

  • The fix reports back to the thread

    Ask for a fix in Slack and its fate comes back where you asked: CI failures, the merge, the close. Reply in the thread to steer the follow-up.

  • Notifications where the team lives

    Connecting creates #polylane-notifications: issue detections, automation results, and the weekly digest, each with a button back to the evidence.

Production context in Slack. Delivered where the team already works.

Issue detections, automation results, usage warnings, and the weekly digest, each with a button back to the evidence. Only Polylane's own critical and high severity detections notify: your monitors already page you, so their alerts are never duplicated here.
