Aurora Rollout Runbook
Overview
Releases leave the main branch every Wednesday at 14:00 UTC. A release candidate is cut automatically, tagged RC, and deployed to the staging cluster within fifteen minutes. Nothing reaches production without passing the full staging suite twice in a row.
Approvals
Every production rollout needs two approvals: the release captain on duty and one engineer from the owning team. The release captain checks the error budget before signing off; if more than 25 percent of the monthly error budget has been burned, the rollout is deferred to the next window.
Canary stage
The canary stage routes 5 percent of production traffic to the new build for 45 minutes. The canary cohort is selected by session hash, so a returning user stays on the same build for the whole window.
Rollback
Rollback is one command: aurora rollback --to-last-good. It repoints the fleet at the previous build and completes in under four minutes. Run it from the deploy bastion, never from a laptop.
This runbook describes how the Meridian web app ships to production through the Aurora pipeline: a weekly release cut , a two-approval gate , an automated canary stage , and a single-command rollback path .
Most summarizers ask for your trust.
A fluent paragraph is easy. A fluent paragraph that's actually true to a 40-page document is the hard part, and the part most AI summarizers skip. Sidenote forces every point to cite the passage it came from, checks those citations server-side, and drops anything it can't ground. So instead of re-reading the whole thing to make sure the summary is right, you click a citation and land on the exact line.
And it works across everything you read, not just uploaded PDFs. Summarize a Confluence runbook, a Notion spec, a SharePoint deck or a long article the same way, or bundle several into a collection and summarize across all of them at once.
