- **Version discovery reads published releases.** For each major version >= 1, the workflow takes
the most recently published non-draft release tagged `v{MAJOR}.*`. A draft release contributes
nothing.
- **Every major is rebuilt.** Each major's docs are built from that major's latest release tag into
its own path (`/v1/`, `/v2/`). A new MAJOR adds a new path; the site root redirects to the newest
release, prereleases included.
- **Every major is rebuilt.** A release-triggered run builds each major from its latest release tag
into its own path (`/v1/`, `/v2/`). A manual dispatch defaults to the same release-tag content,
or can build every major from `release/{MAJOR}.x`, using `main` for its matching major,
by selecting `docs_source=latest-branches`. A new MAJOR adds a new path; the site root redirects
to the newest release, prereleases included.
- **Orchestration comes from `main`.** The scripts and picker assets are always checked out from
`main`, while each version's content comes from its release tag. A docs fix that lives only in a
`main`. Release-triggered and default manual runs use release-tag content; a manual
`docs_source=latest-branches` run uses source-branch content. A docs fix that lives only in a
release branch will not affect orchestration.

**Refresh the docs without a new release** — when documentation content needs correcting after the
release, the docs workflow accepts a manual dispatch that rebuilds one major version's content from
an arbitrary ref, without minting a product release:
**Rebuild the released docs** — use the default `release-tags` source to retry a failed Pages
deployment after a release, without minting a product release:
```
gh workflow run docs.yml --field docs_ref={branch-tag-or-commit}
gh workflow run docs.yml --field docs_source=release-tags
```
The ref's major version, read from `src/Directory.Build.props`, must have a published release; the
workflow fails fast if it does not. This replaces only the matching major's HTML — orchestration
and all other versions are unaffected.
**Refresh docs without a new release** — select `latest-branches` to rebuild every published major
from its current source branch (`release/{MAJOR}.x`, using `main` for its matching major):
```
gh workflow run docs.yml --field docs_source=latest-branches
```
The workflow fails instead of silently using a release tag when any major has no matching branch.
