Merged

Conversation
Use one isolated Fern CLI runner and validate the published checkout. Give same-repository previews verified Git context and preserve candidate configuration changes in a temporary clone. Upgrade fern-api from 5.38.0 to 5.144.1 (Apache-2.0) and align documentation CI on Node 24. No bundled third-party code or NOTICE changes.

Phase 1 can only preview the existing configuration. The edition configuration and workflow selection are introduced together in phase 3. Relates to #2214 Signed-off-by: Stephanie Baum <sbaum@nvidia.com>

TL;DR
Phase 1 of the docs-edition migration adds validation before canonical publishing and gives previews verified Git context for branch-based versions. It upgrades fern-api from 5.38.0 to 5.144.1 and aligns docs CI on Node 24, while keeping the current product navigation.
Additional Details
Manual preview selection in P1 offers
noneandexisting. Commit3599b626daddresses the CodeRabbit finding by moving theeditionchoice to #2226, wherefern/edition-preview.ymlis introduced. Workflow lint and both preview-helper tests pass; CodeRabbit has resolved the review thread.A shared runner installs the pinned Fern CLI into a version-specific temporary cache. Validation, publishing, and previews use that runner. The publisher validates its exact checkout, permits canonical publication only from main, and serializes publishing without canceling an active publication.
The preview workflow checks the PR repository, head commit, and branch before checkout. It retains the same-repository credential boundary and uses the checked-out Git remote for future ref versions. Changed-file detection covers MDX and navigation. The local preview helper can stage an alternate configuration in a temporary clone without changing the working tree, and a failed Fern build fails the job even if it printed a URL.
The four existing historical links in the 0.6.0/0.6.1 fake-GPU guides were corrected with explicit approval in commit
9bb821e77. Full local docs validation and the GitHubdocsandFern Checkjobs now pass. This PR is ready for review.For the Reviewer
Review and merge this PR first. After it lands, rebase the P2 changes onto updated main and retarget #2225 to main; carry P3 forward on top of P2. The repository uses squash merges, so retargeting alone can leave parent commits in a child diff. Do not merge the children into their current parent branches.
Review the publishing gate, preview source verification, and failure-propagation tests first. The later edition and navigation changes will be separate stacked PRs. New workflow_run behavior must also be exercised after this workflow reaches the default branch.
Dependency review: fern-api 5.144.1 ships an Apache-2.0 license, which is allowed by this repository. This updates a CI tool; no third-party source is bundled and NOTICE is unchanged. Node 24 matches the runtime already used by build-test.
For QA
Passed locally: docs-version-sync Go tests, generated-block consistency check, focused runner/preview tests, actionlint 1.7.12, shellcheck, and git diff --check.
Cumulative hosted builds exercised Node 24 and Fern 5.144.1. Phase 3 records a 1,391-route baseline, including all 156 sitemap URLs, and historical content comparison results. Local CLI validation used Node 22.21.0.
Current checks: docs, Fern, helper/Go, Markdown/workflow lint, license, Helm, and release-helper checks pass. The historical-link-fix head completed the full suite. CI is rerunning for the small preview-selection follow-up; its Fern and workflow-lint checks pass. The strict legacy preview and its workflow run pass.
After P1 merges, exercise the actual two-workflow preview from the default branch before advancing the stack.
