From b5031eeaf4454fd3d16ad9d5c5e72022de9d6084 Mon Sep 17 00:00:00 2001 From: Lain Date: Thu, 6 Aug 2026 07:12:40 +0200 Subject: [PATCH] fix(release): verify the tag, and publish the changelog not the blurb MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit v5.0.0 shipped with an UNVERIFIED tag. Three things had to be wrong at once, and all three were: - gen-ci-signing-key.sh generated the key with Name-Real but no Name-Email, so its uid carried no address at all. GitHub reported it as `emails=` — empty. - bootstrap-ci.sh never registered the key on the GitHub ACCOUNT. It certified the key with the YubiKey, which is a different mechanism: certification makes `gpg --verify` meaningful to a human, registration is what the "Verified" badge reads. The two were conflated. - release.yml tagged as `github-actions[bot]@users.noreply.github.com`, an address that cannot appear on anyone's key. GitHub marks a signature verified only when the tagger email, an email on a uid of a registered key, and a verified account email all agree. Any one of the above defeats it permanently. The address is now DERIVED, never written down. gen-ci-signing-key.sh reads it from the maintainer key via `git config user.signingkey`; release.yml reads it from the signing key it just imported. Each link derives from the previous one, so rotating the key is sufficient on its own and nothing can drift out of step. It also keeps the address out of the repository — this project deliberately publishes no contact email anywhere (CHANGELOG 5.0.0), and a committed script is published. Both now fail loudly where they used to continue: the workflow aborts if the imported key has no email rather than producing another unverifiable tag, and the generator aborts rather than minting another unusable key. Also in bootstrap-ci.sh: it no longer re-adds a required reviewer (publication is automatic on merge to main, and on a single-collaborator repository the merge already is the human act), and it adds `main` to the deployment branch policy — without that entry the job is rejected before the workflow is even reached, which is how the first attempt failed. Finally, the GitHub Release now carries CHANGELOG.md instead of RELEASE_NOTES.md. The latter is the Marketplace copy — emoji-led, second person — and that register belongs on a storefront where someone is deciding whether to install, not in front of a person who arrived at a release page because something broke. Different readers, different documents: build.gradle.kts still feeds the Marketplace panel from RELEASE_NOTES.md. The extracted section is ~27 KB against a 125 000-character limit, and an empty extraction now fails the release rather than publishing blank notes.
