+# Content and tutorial maintenance
+
+Both original daily schedules are preserved. The factory triages failing pull
+requests into deduplicated investigation issues. Daily maintenance runs meaningful
+repository-specific checks before any AI call. Neither workflow merges PRs.
+
+- BFS-Projects: README structure, local link targets, JSON and workflow syntax
+- javascript-solutions: those checks plus every root extensionless JavaScript
+  snippet parsed with Node, including filenames with spaces, and focused regression tests
+- tutorials-files: those checks plus tracked JavaScript syntax, focused regression
+  tests, and the actual nested client-side-storage-api-handling TypeScript/Vite build
+
+Root npm commands are not applicable. The tutorial's nested project has no lockfile;
+its manifest is installed with scripts disabled and no lockfile writes in a temporary
+copy. Dependency resolution is therefore not reproducible. External link availability,
+HTML/browser behavior, and a complete application test suite are not covered. The
+workflow reports these limits; actual validation failures fail the run.
+
+Automatic source/dependency repair is unsupported because these repositories lack
+sufficient comprehensive test coverage. The AI proposal path is **README.md only**;
+source snippets and the repository inventory provide read-only context. Manual or
+label-triggered issue requests must name README.md and produce documentation proposals,
+not claims that code issues were implemented. Unsupported requests are explicitly
+reported as skipped. One open documentation/review-required proposal blocks duplicates.
+
+The shared maintenance guard verifies protected file bytes, tracked file sets,
+executable modes, Git HEAD and index. It catches provider failures even when aider
+exits zero. Missing credentials fail a requested AI attempt. No model calls run for
+pull requests or default-branch pushes. Pushes run validation only. Guards and repository checks must pass again before draft publication.
+No secrets or access settings are added. Package validation receives no GitHub or
+OpenAI environment tokens; checkout credentials are not persisted. These publication
+checks are not a sandbox for executing repository code.
+
+Run:
+
+    PYTHONDONTWRITEBYTECODE=1 python -m unittest discover -s .github/maintenance -p 'test_*.py'
+    bash -n .github/maintenance/content.sh
+    PYTHONDONTWRITEBYTECODE=1 python .github/maintenance/content.py validate
+
+Python requires PyYAML==6.0.3; use Node 22 (22.12 or later for the Vite tutorial).
+Generated drafts still require human review and exact-head CI. GITHUB_TOKEN events
+may require a maintainer to approve workflow runs. A draft is not a claim that remote
+CI passed or that an AI provider has available credit.
