Release Flows

Two inputs pick how releases reach main. Neither is the default.

#Straight to main

Each push with release-worthy commits gets a release commit (CHANGELOG.md, package.json, commit files) and a tag, pushed together. The commit carries [skip ci], so it doesn't trigger another run.

gitGraph TB:
  commit id: "feat: login"
  commit id: "chore(release): 1.0.0" tag: "v1.0.0"
  commit id: "fix: typo"
  commit id: "chore(release): 1.0.1" tag: "v1.0.1"
  commit id: "docs: readme"
  commit id: "feat: logout"
  commit id: "chore(release): 1.1.0" tag: "v1.1.0"

docs: readme alone releases nothing: docs doesn't bump by default (see rules).

#Canary + release PR

main never gets a commit from releaser. Each push tags a canary on HEAD and rebuilds the release PR on top of it; merging the PR tags the stable version on the release commit.

gitGraph TB:
  commit id: "feat: login" tag: "v1.1.0-canary.1"
  commit id: "fix: typo" tag: "v1.1.0-canary.2"
  commit id: "chore: tidy"
  branch releaser/release
  commit id: "chore(release): 1.1.0" tag: "v1.1.0"
  checkout main
  merge releaser/release id: "Merge PR #12"
  commit id: "feat: search" tag: "v1.2.0-canary.1"

• chore: tidy makes no canary: nothing release-worthy since canary.2. The PR is still rebuilt.
• The graph shows a merge commit. With a squash merge, v1.1.0 goes on the squashed commit on main instead; with a rebase merge, on the replayed one.
• releaser/release is force-pushed on every push, so the PR always sits on top of main: it never conflicts and its notes are current.

  Dev->>Main: merge fix: typo
  Main->>CI: push
  CI->>GH: tag v1.1.0-canary.2, prerelease
  CI->>GH: force-push releaser/release, update the PR
  Dev->>Main: merge the release PR
  Main->>CI: push
  CI->>GH: tag v1.1.0 on the release commit, release (Latest)

Setup, token and check details: Canaries and release PR.

#Canary, manual stable

Canaries as above, no PR. A run without prerelease (for example a workflow_dispatch job with the same other inputs) releases straight to main.

gitGraph TB:
  commit id: "feat: login" tag: "v1.1.0-canary.1"
  commit id: "fix: typo" tag: "v1.1.0-canary.2"
  commit id: "chore(release): 1.1.0" tag: "v1.1.0"
  commit id: "feat: search" tag: "v1.2.0-canary.1"

That run pushes to main, so it needs the same branch protection bypass as straight to main.

#What one push does

  merged -- yes --> stable["tag vX.Y.Z on that commit<br/>GitHub release, Docker :latest"]

  pr -- yes --> rebuild["rebuild chore(release): X.Y.Z<br/>force-push releaser/release<br/>open or update the PR"]
  pr -- no --> done([done])
  rebuild --> done

Every push comes last in its box: releases and canaries run prepare, artifacts and Docker :X.Y.Z first, the PR runs prepare first. A failure leaves the remote untouched. Docker :latest or :canary moves after the push.
