 - **UI**: `src/app/(frontend)/wiki/`: `/wiki` index (`WikiIndex`: search, tag filter, category tabs, "New page"), `/wiki/new`, `/wiki/[slug]` (detail: `WikiContent` render + `WikiToolbar` with Edit/History/Lock/Delete; `LockdownBanner` when locked; missing pages show a "Create this page" CTA that prefills `?title=`), `/wiki/[slug]/edit` (redirects to `/wiki/new?title=` for missing pages, shows `LockdownBanner` when locked), `/wiki/[slug]/history` (`RevisionList` with type badges and moderator-only Restore). Tests: `tests/int/wiki.int.spec.ts`.
 - **Event targets**: `wiki-pages`, `wiki-revisions`, `wiki-templates` added to `GameEventLogs` `TARGET_COLLECTIONS` and `emit.ts` `targetCollection` union. Wiki event types in `eventTypes.ts`.
 - **Database**: migration batch 28 `src/migrations/20260904_230838_add_wiki_collections.ts`: tables `wiki_pages` (+ `_texts`), `wiki_revisions`, `wiki_templates`, plus the three wiki values added to the `game_event_logs` `target_collection` enum. Dev uses `bun run payload migrate` for schema changes (`push: false`).
-- **Gotchas**: image uploads go through the `uploadWikiImage` server action in `src/app/(frontend)/wiki/actions.ts` (any logged-in user, image MIME only, 8 MB cap, stored in `media` with `read: () => true` so images are public; the editor toolbar's "Upload image" button inserts `![alt](/api/media/file/<filename>)` — requires `serverActions.bodySizeLimit` (10mb) in `next.config.mjs`); lockdown blocks edit/restore server-side (actions throw `"This page is locked and cannot be edited."`); restore/delete/lock are intelligence-qualification gated; `WikiRevisions` denies create/update/delete outright, so all revision writes go through the service layer with `overrideAccess`.
