Foundation & safety phase of the wiki upgrade (see WIKI_UPGRADE.md).
Schema (additive, idempotent via ensureSchema):
- new wiki_categories table; wiki_pages gains category_id, excerpt,
published, published_at, sort_order, and a FULLTEXT index
- migration ALTERs guarded with IF NOT EXISTS for existing databases
- seed reworked into 4 sections with the 8 starter pages assigned
Security:
- new utils/sanitizeHtml.js (sanitize-html allowlist); wiki bodies are
sanitized on every save, and the article renders through DOMPurify
- strips <script>, event handlers (onerror), and javascript: URLs
Backend:
- public: published-only list with ?category filter + /wiki/categories
- admin: extended page CRUD, PATCH publish toggle, category CRUD;
drafts visible to admin, hidden from public
- all writes logged to activity_log
Frontend:
- data-driven public wiki index (sections + real descriptions; removed
hardcoded blurbs/Roman numerals) with ?category filtering
- article: category breadcrumb + sanitized render
- admin: Section/Status columns, draft/publish + section + excerpt in the
editor, and a Manage sections modal
Verified end-to-end against MariaDB 11: migration clean, XSS neutralized,
drafts hidden, client builds, server boots.
