From 978faa619b597f49b7e3cfad57f47c9b81376ce5 Mon Sep 17 00:00:00 2001 From: vaaraio <267591518+vaaraio@users.noreply.github.com> Date: Thu, 28 May 2026 17:16:06 +0300 Subject: [PATCH 1/6] chore(release): post-merge tag script + token-based npm-only fallback scripts/release_tag_after_merge.sh covers the "PR already merged via GH UI" path. release_merge_and_tag.sh assumes the PR is open and starts with gh pr merge, so it cannot finish the tag work once the merge already happened. The new script fetches origin/main, moves v (and an optional co-tag) to the merged SHA, prints the gated push command. scripts/release_publish_npm_manual.sh splits the npm side of the manual fallback out of release_publish_manual.sh. Token-based via VAARA_NPM_TOKEN, no interactive npm login. For the case where the GH Actions npm step flakes but PyPI trusted publishing already shipped. Ships without npm provenance, same constraint as the existing all-in-one manual script. scripts/RELEASE.md gets sections 3b and 4b documenting the two new paths. --- scripts/RELEASE.md | 25 +++++++++++ scripts/release_publish_npm_manual.sh | 63 +++++++++++++++++++++++++++ scripts/release_tag_after_merge.sh | 53 ++++++++++++++++++++++ 3 files changed, 141 insertions(+) create mode 100755 scripts/release_publish_npm_manual.sh create mode 100755 scripts/release_tag_after_merge.sh diff --git a/scripts/RELEASE.md b/scripts/RELEASE.md index fccc6d0..4b75eaa 100644 --- a/scripts/RELEASE.md +++ b/scripts/RELEASE.md @@ -74,6 +74,18 @@ provenance, publish to PyPI via trusted publishing, sign with Sigstore, publish `@vaara/client` to npm with provenance, create the GitHub Release. +## 3b.
