Manage Foundry VTT JournalEntries with multi-page + multi-type CRUD via 15 actions. Use this when: - Writing lore, quest briefings, or session notes as a multi-page JournalEntry (text/image/pdf/video pages), e.g. {action:"create-entry", name:"Quest: Find the Witch Hunter", pages:[...]}. - Editing an entry's top-level metadata (name, folder, ownership) or a specific page's content (action:"update-entry"/"update-page"). - Organizing pages under named categories, or reordering them (action:"add-category"/"assign-page-to-category"/"reorder-pages"). - Broadcasting an entry to all connected players without persisting anything (action:"show-to-players"). - Auditing existing journals by name-prefix template convention (filterTemplate/filterQuests) before creating a new one. Do NOT use this for the map-pin anchor that points at a journal page from a scene — use `note` instead; `journal` owns the JournalEntry/page content itself, not its scene placement. **Actions:** - **create-entry**: Create a JournalEntry with optional inline pages (text/image/pdf/video) + categories. Returns {id, name, pageIds, categoryIds}. - **update-entry**: Update top-level fields (name, folder, sort, ownership, flags) on an existing entry. Use update-page for page content. - **delete-entry**: Permanently delete a JournalEntry and all its pages + categories. ⚠️ Irreversible. - **list-entries**: List world entries. filterTemplate:"" matches name-prefix ":" (case-insensitive); filterQuests:true aliases filterTemplate:"quest"; includeContent:true populates each entry's first text-page body. - **get-entry**: Fetch a single entry. Deep by default; shallow:true returns {id, name, pageIds, pageCount, categoryCount}. - **add-page**: Append a page (text/image/pdf/video) to an entry. sort auto-increments by 1000s when omitted. - **update-page**: Partial-diff update of an existing page's writable fields. Type cannot change. Returns {entryId, pageId, changes}. - **delete-page**: Remove a single page from an entry. - **reorder-pages**: Reassign sort values on every page. pageIds must be the complete ordered list (rejects partial reorder). - **add-category**: Add a JournalEntryCategory header to an entry. - **update-category**: Update a category's name/sort/flags. - **delete-category**: Remove a category. Previously assigned pages become uncategorised. - **assign-page-to-category**: Set or clear (categoryId:null) a page's category FK. - **show-to-players** (Phase 9B): Display the entry to all connected players (JournalEntry#show(true) socket broadcast). Required: entryId. Transient — no persisted state, no per-user targeting. - **duplicate-entry** (Phase 9B): Clone the entire JournalEntry (pages + categories) as a new world entry named " (Copy)". Required: entryId. Returns {sourceId, newId, name}. **Page types** (input on create-entry / add-page): - text: {type:"text", name, text:{content, format?:1|2}, title?:{show,level}, sort?, category?} - image: {type:"image", name, src, image?:{caption}, ...} - pdf: {type:"pdf", name, src, ...} - video: {type:"video", name, src?, video?:{autoplay,loop,width,height,volume,timestamp,controls}, ...} **Text page format**: 1=HTML (ProseMirror default), 2=Markdown. CONST.JOURNAL_ENTRY_PAGE_FORMATS. **HTML/CSS preservation** (text pages, format:1): round-trips byte-identical except sanitisation of
