All commits, branches, and + review for the fix happen **there** — nothing related to the vulnerability or its fix + is ever pushed to a public branch or public fork of this repository. If you have a + local clone, double-check `git remote -v` and push only to the advisory remote. +2. **Deploy first.** Ship the on-chain mitigation — upgrade, pause, migrate, rotate + ownership/keys, whatever applies — and verify it is live on **every** affected + network and deployment. +3. **Merge and disclose last.** Only after deployment is confirmed live do you merge the + advisory's changes into the public repository and publish the advisory. + +**Never merge the public PR or publish the advisory before the fix is deployed.** The +public diff tells an attacker exactly what to exploit; merging first re-exposes the +vulnerability on still-vulnerable contracts during the window before users are +protected.
