GitHub Pages serves those deep -redirects with HTTP 404; browsers follow the JavaScript redirect. +This website imports that same generated output under +https://fastled.io/docs/, so matching existing documentation URLs serve their +content directly. Navigation, search, styles, scripts, and images come from the +upstream bundle. The website does not run Doxygen or check out FastLED master. + +### Publication and update checks + +Dox publishes a small [publication manifest](https://fastled.github.io/dox/publication.json) +with the source release, publication generation, and SHA-256/size of a versioned +GitHub release asset. These downloads outlive the one-day Pages Actions artifact. +`scripts/import_docs.py` verifies the download and its embedded release metadata +before adding the documentation to `_site/docs/`. Import errors fail the workflow +before deployment, leaving the live website intact. + +The existing publishing workflow checks daily at **10:47 UTC**. A changed +publication triggers deployment, including an intentional rebuild of the same +release tag. Unchanged documentation checks skip build and deployment. Normal +website pushes still deploy the website with the latest published documentation. +Use **Run workflow → docs_only: true** for an immediate check that deploys only +if documentation changed. + +As in dox, `scripts/record_check.py` records a successful check at most every +30 days on `automation/release-checks`.
