## Day 1 14:30 — Rollback plan for v2.3 deploy
## Day 1 16:00 — Rollback plan for v2.3 deploy
I built the rollback script and the runbook so that a v2.3 failure can be reversed in one verified step. The script restores the Postgres dump, reverts the sync engine binary, and flips the feature flag to the previous stable version. Ravi will run the restore test in staging before we ship, and I’m blocking the v2.3 release until that test passes. No patient record should ever be at risk because we skipped a rollback check.
## Day 2 13:00 — Rollback plan for v2.3 deploy
I built out the rollback runbook for the v2.3 sync engine deploy. It defines a strict pre-deploy checklist that verifies the Postgres dump and the on-disk WAL archive before we even touch the production binary. The one-command rollback script is wired up to restore the exact database state and revert the Rust binary. I made it explicit that if the verification step fails, the deploy is blocked. No flashy features, no heroic saves — just a boring, reliable way to undo a bad deploy. I've added it to my personal dashboard as a hard gate.
## Day 3 15:00 — Rollback plan for v2.3 deploy
I am treating the v2.3 deploy as a high-risk event until proven otherwise. I have written a strict runbook that enforces a manual verification step before any traffic is cut over. The rollback is a single, atomic command that restores the Postgres snapshot and reverts the Rust sync engine binary to the last known-good version. I am blocking the deploy until Ravi Patel has confirmed the backup integrity tests pass and Marcus Chen has signed off on the rollback drill. We do not ship a flashy feature if it risks a patient record, and this plan ensures we can undo the mess in under five minutes.
## Day 4 11:30 — Rollback plan for v2.3 deploy
I built the rollback playbook for v2.3 because a deploy without a rollback plan is just a controlled explosion, and I refuse to ship that. I wrote a strict, step-by-step runbook that prioritizes data integrity over speed. The process mandates a verified, checksummed backup of the Postgres cluster before any schema migration. If the migration fails, the rollback is a single command that restores the database from that verified snapshot and reverts the sync engine to the last known good binary. I also added a post-rollback health check to ensure the sync engine is idle and the database is consistent. No flashy features, just boring reliability.
