# KTX release runbook
This runbook covers the maintainer workflow for publishing `@kaelio/ktx` to
npm through GitHub Actions. The workflow uses semantic-release to choose the
next version, update release metadata, publish the package, create the GitHub
release, and commit prerelease files back to the `next` branch.
## Release channels
KTX has two npm release channels:
- `rc` publishes prereleases such as `0.1.0-rc.2` to the npm `next` tag.
- `stable` publishes normal releases such as `0.1.0` to the npm `latest` tag.
Run rc releases from the source branch you want to publish. The workflow
creates or updates the `next` prerelease branch from that source branch before
running semantic-release, because semantic-release requires a dedicated
prerelease branch in addition to the stable `main` branch.
Run stable releases only from `main`. The workflow rejects stable releases from
other branches.
## Prerequisites
Before you publish, confirm these requirements:
- npm Trusted Publishing is configured for `@kaelio/ktx`.
- The trusted publisher points at the `Kaelio/ktx` repository and the
`.github/workflows/release.yml` workflow.
- The workflow keeps `id-token: write` permission so npm can verify the
GitHub Actions run through OpenID Connect.
- The repository has release metadata in `release-policy.json` for the current
public package line, such as `0.1.0-rc.1` or `0.1.0`.
If no stable baseline tag exists, semantic-release treats the stable run as the
first release. KTX seeds that first stable release from the base version in
`release-policy.json`, so `0.1.0-rc.6` promotes to `0.1.0` instead of
semantic-release's default `1.0.0`.
KTX blocks automatic major releases. A major version requires an intentional
manual release path that updates release metadata and creates the intended
version explicitly; don't rely on semantic-release commit analysis for major
bumps.
## Dry-run a release
Use a dry-run to verify the next version and generated release notes without
publishing to npm.
1. Open **Actions** in GitHub.
2. Select **KTX Release**.
3. Select the branch to release from.
4. Set **release_kind** to `rc` or `stable`.
5. Leave **publish_live** set to `false`.
6. Optional: Set **force_release** to `true` when you need a patch release even
if semantic-release doesn't find a releasable commit.
7. Run the workflow.
The dry-run uses the same semantic-release configuration as a live release. For
rc releases, it can create or update the `next` branch. It doesn't publish to
npm and doesn't commit release files.
## Publish an rc release
Publish an rc release when you need a prerelease package for validation before
promoting to `latest`.
1. Open **Actions** in GitHub.
2. Select **KTX Release**.
3. Select the source branch to release from.
4. Set **release_kind** to `rc`.
5. Set **publish_live** to `true`.
6. Optional: Set **force_release** to `true`.
7. Run the workflow.
The workflow merges the selected source branch into `next`, publishes
`@kaelio/ktx` with `--access public --tag next`, runs the published package
smoke test, creates a GitHub release, and commits `CHANGELOG.md`,
`package.json`, and `release-policy.json` on `next`.
## Publish a stable release
Publish a stable release from `main` after you have validated an rc package.
1. Open **Actions** in GitHub.
2. Select **KTX Release**.
3. Select `main`.
4. Set **release_kind** to `stable`.
5. Set **publish_live** to `true`.
6. Optional: Set **force_release** to `true`.
7. Run the workflow.
The workflow publishes `@kaelio/ktx` with `--access public --tag latest`, runs
the published package smoke test, and creates a GitHub release. Stable releases
don't commit release metadata back to `main`, because `main` is protected and
requires changes through pull requests.
## Release metadata
semantic-release calls `scripts/update-public-release-version.mjs` during the
prepare step. That script updates:
- `package.json` with the semantic-release version.
- `release-policy.json` with `publicNpmPackageVersion`, npm publish settings,
and the published package smoke-test version.
The artifact packaging and readiness scripts read `publicNpmPackageVersion`
from `release-policy.json`, so manual version edits in build scripts aren't
needed for rc releases. Stable releases use the updated metadata during the
workflow run, but that generated metadata isn't committed back to `main`.
The bundled Python runtime wheel also derives its version from
`publicNpmPackageVersion`. Stable npm versions are reused as-is, and rc
versions are normalized to Python's version format. For example,
`0.1.0-rc.2` becomes `0.1.0rc2` in the `kaelio-ktx` wheel filename and wheel
metadata.
## npm authentication
The release workflow publishes through npm Trusted Publishing. It doesn't use
an `NPM_TOKEN` secret, and the publish step doesn't set `NODE_AUTH_TOKEN`.
If npm returns an authentication error, check the Trusted Publishing settings
for the `@kaelio/ktx` package before adding token-based authentication back to
the workflow.
