Contributes to #3107

📝 Walkthrough

Summary by CodeRabbit

• New Features
  • Added automated API documentation publishing for branch builds.
  • Added dry-run API documentation publishing for pull request validation.
  • Documentation publishing now supports version mapping for legacy and stable releases.
  • Added documentation navigation improvements, including centered navigation elements and a version switcher for accessing different documentation versions.

Walkthrough

The workflows now publish raft API documentation after builds. Branch builds publish live documentation, while pull requests run a dry-run publication. The build concurrency group includes build_type. Sphinx now configures centered navigation and version switching.

Changes

API documentation publishing

Layer / File(s)	Summary
Workflow coordination .github/workflows/build.yaml	The build concurrency group now includes inputs.build_type or the branch default.
Live API documentation publishing .github/workflows/build.yaml	The build workflow adds a branch-only publish-api-docs job. It invokes the shared publisher for raft with live publishing and configured version mappings.
Pull request dry-run publishing .github/workflows/pr.yaml	The pull request workflow adds a dependent publish-api-docs job. It invokes the shared publisher in dry-run mode and adds the job to pr-builder dependencies.
Documentation version switcher docs/source/conf.py	Sphinx configures centered navbar elements and a version switcher using the RAFT versions manifest and current version.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 64398

The PR changes public documentation publishing, but the current configuration can prevent version navigation from rendering, publish a different revision than the one built, and use an unsupported version manifest configuration. This could make the public API docs incomplete or inconsistent, so the PR is not merge-ready until these issues are corrected or explicitly accepted.

- Around line 128-131: Update the publish-api-docs invocation in the
workflow_dispatch path to pass the checked-out build revision `${{ inputs.sha
}}` through the workflow’s supported sha/ref input, ensuring the publisher uses
the same revision as docs-build; alternatively prevent live publishing when the
revisions differ.

configuration in docs/source/conf.py, verifying the navbar component list
includes the version switcher and that version_match handles a single-digit
minor release correctly. Update the relevant documentation configuration or
build test without changing unrelated behavior.
- Line 125: Update the navbar_center configuration value to a list of component
names instead of a comma-separated string, preserving the existing navbar-nav,
version-switcher, and navbar-external-links entries and their intended order.
