release: commit cosign.pub — signing engages for the first time (#376 bootstrap) - #961
Merged
Conversation
…bootstrap) The key pair was generated on the release box in July but the public half never landed in the repo, so release.sh's signing condition (key + committed cosign.pub) has never fired and every bundle to date shipped unsigned. Committing the pub key completes the #376 rollout: the pipeline signs from the next cut, the bundle ships the key, and installs bootstrap verification on their first upgrade to it. Also corrects the 1.18.1 changelog account to this real story. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Investigating v1.18.0's missing bundle signature surfaced the real state: signing has NEVER engaged. release.sh's condition is
cosign present && COSIGN_KEY set && cosign.pub committed at repo root— the key pair was generated on the release box on Jul 24, but the public half never landed in the repo, so every release to date shipped unsigned (v1.16.0 and v1.17.0 also have no .sig asset) and no install holds a key.This commits
cosign.pubat the root (completing the #376 rollout — the pipeline signs from the next cut and the bundle ships the key, so installs bootstrap verification on their first upgrade), and corrects the 1.18.1 changelog account. Root-cause hardening is #960.🤖 Generated with Claude Code
