Connectivity phase of the wiki upgrade (see WIKI_UPGRADE.md).
Schema (additive new tables): wiki_tags, wiki_page_tags, wiki_links.
Internal links & backlinks:
- new wiki.links.js parses a saved body for /wiki/<slug> (and data-wiki-slug)
targets; wiki_links is rebuilt on every save
- article shows a "Linked from" section (published backlinks) and renders
links to non-existent pages as red links (server returns missing_links)
- editor gains an internal-link picker listing existing pages
Tags:
- pages accept a tags[] array; tags upsert on save, page tag-set is replaced,
and orphaned tags are auto-pruned (on save and delete)
- public/admin list filter by ?tag=; /wiki/tags lists tags with published counts
- article shows tag chips; the index has a flat tag-filtered view; editor has a
comma-separated tags field
Verified end-to-end: A->B backlink appears, red link detected, link index
rebuilds on edit, tag filtering + chips + pruning all work.

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.
