-- allium: 1
-- bDS Miscellaneous Editor Views
-- Scope: UI content area — dashboard, menu editor, metadata diff, git diff,
--   documentation, validation, find duplicates, import analysis
-- Distilled from: Editor.tsx (Dashboard), MenuEditorView.tsx,
--   MetadataDiffPanel.tsx, ImportAnalysisView.tsx

-- Describes the layout and behaviour of smaller editor views that don't
-- warrant their own spec file.

-- ─── Menu editor view ────────────────────────────────────────

-- Visual editor for the OPML navigation menu (meta/menu.opml).
-- See menu.allium for data model.

-- Layout: toolbar at top, tree view of menu items below.
-- Each item row: drag handle, icon, label, type badge, action buttons.
-- Nested items indented to show hierarchy.

-- ─── Menu editor actions ────────────────────────────────────

rule MenuAddItem {
    when: MenuItemAdded(kind, data)
    -- kind = page: opens lazy-loaded page picker (posts with "page" category)
    -- kind = category_archive: opens lazy-loaded category picker
    -- kind = submenu: creates empty container node for nesting children
    -- kind = home: always available, maximum one allowed
    ensures: MenuTreeUpdated()
}

rule MenuSave {
    when: MenuSaveRequested()
    -- Serializes tree to OPML 2.0, writes meta/menu.opml
    ensures: MenuFileWritten()
}

rule MenuMoveItem {
    when: MenuItemMoved(item_id, direction)
    -- direction = up | down | indent | unindent
    -- Up/Down: reorder within same nesting level
    -- Indent: nest under previous sibling (becomes child)
    -- Unindent: move to parent's level (becomes next sibling of parent)
    requires: not is_home_item(item_id)
        -- Home item is protected: cannot be moved or deleted
    ensures: MenuTreeUpdated()
}

rule MenuDeleteItem {
    when: MenuItemDeleted(item_id)
    requires: not is_home_item(item_id)
    -- Removes item and all children, no confirmation dialog
    ensures: MenuTreeUpdated()
}

-- Drag-and-drop reorder:
--   Drag handle on each item
--   Auto-expand collapsed submenus on hover (450ms delay)
--   Drop indicators show target position and nesting level

config {
    menu_drag_expand_delay: Integer = 450
}

-- ─── Metadata diff view ──────────────────────────────────────

-- Shows DB vs filesystem differences for all entity types.
-- See metadata_diff.allium for diff field definitions.

-- Layout: scan button at top, results grouped by entity type below.
-- Each diff entry: entity name, field name, DB value, file value,
--   two sync buttons (DB->File, File->DB).

-- ─── Metadata diff actions ──────────────────────────────────

-- Scan: runs 4 parallel scans (posts, media, scripts, templates)
--   Compares DB records against filesystem files field by field
--   Results grouped by entity type, sorted by entity name
--   Shows count of differences per entity type in section header

-- Per-field sync:
--   DB -> File button: overwrites file field with DB value
--   File -> DB button: overwrites DB field with file value
--   No confirmation dialog for individual field syncs
--   Button disappears after successful sync (field now matches)

-- Orphan file import:
--   Files on disk with no matching DB record shown separately
--   "Import" action creates DB record from file metadata
--   Appears at bottom of each entity type section

-- ─── Git diff view ────────────────────────────────────────────

-- Renders diff for a file (working tree vs HEAD) or a commit.
-- File diff: id = "git-diff:{filePath}"
-- Commit diff: id = "git-diff:commit:{commitHash}"
-- Supports inline and side-by-side diff display modes (from editor settings).
-- No actions beyond viewing — changes are managed via git sidebar.

-- ─── Documentation views ─────────────────────────────────────

-- documentation:     renders DOCUMENTATION.md as styled HTML
-- api_documentation: renders API.md as styled HTML

-- ─── Site validation view ───────────────────────────────────

-- Compares sitemap.xml to generated HTML files on disk.
-- Detects missing pages, orphan HTML, and stale content.

value SiteValidationReport {
    expected_url_count: Integer
    existing_html_count: Integer
    missing_url_paths: List<String>       -- in sitemap, no HTML on disk
    extra_url_paths: List<String>         -- HTML on disk, not in sitemap
    updated_post_url_paths: List<String>  -- source .md newer than HTML
}

-- Layout: scan button, summary line, three URL list sections.
-- Summary: "Expected URLs: N — Existing HTML URLs: N — Missing: N — Extra: N — Updated: N"
-- Each section: heading, list of URL paths, or "None found".

rule SiteValidationScan {
    when: SiteValidationScanRequested()
    -- Parses <loc> entries from sitemap.xml into expected URL set
    -- Scans HTML output dir for index.html files (zero-byte = missing)

    ensures: SiteValidationReport
}

rule SiteValidationApply {
    when: SiteValidationApplyRequested(report)
    -- Classifies affected paths into generation sections (core, single, category, tag, date)
    -- Renders only affected sections in parallel
    -- Deletes extra HTML files, removes empty directories
    -- Regenerates calendar if anything changed
    -- Rebuilds search index if anything rendered or deleted
    -- Toast: "Validation applied: N rendered, N deleted"
    ensures: GenerateSiteRequested(sections: report.affected_sections)
}

-- ─── Translation validation view ───────────────────────────

-- Checks translation integrity across DB rows and filesystem files.
-- NOT a matrix view — it is a list of issues found.

    checked_database_row_count: Integer
    checked_filesystem_file_count: Integer
    invalid_database_rows: List<TranslationValidationIssue>
    invalid_filesystem_files: List<TranslationValidationIssue>
}

value TranslationValidationIssue {
    issue: String
    -- Issue kinds:
    --   missing_source_post: translationFor points to nonexistent post
    --   same_language_as_canonical: translation language matches source post language
    --   do_not_translate_has_translations: source post is doNotTranslate but has translations
    --   content_in_database: published translation still has content in DB (should be on disk)
    translation_id: String?
    translation_for: String
    canonical_language: String?
    translation_language: String
    title: String?
    file_path: String?
}

-- Layout: Revalidate + Fix Issues buttons, summary line, two issue sections.
-- Summary: "Checked DB rows: N — Checked files: N — Invalid DB rows: N — Invalid files: N"
-- Each issue rendered as card with coloured left border.
-- Card shows: issue label, source post ID, translation ID, title, languages, file path.

rule TranslationValidationScan {
    when: TranslationValidationScanRequested()
    -- Database pass: checks all translation rows for integrity issues
    -- Filesystem pass: scans posts/ for translation .md files, checks frontmatter
    ensures: TranslationValidationReport
}

rule TranslationValidationFix {
    when: TranslationValidationFixRequested(report)
    -- content_in_database: flushes content to .md file, sets content = null in DB
    -- missing_source_post | same_language_as_canonical | do_not_translate:
    --   DB issues: deletes translation row
    --   Filesystem issues: deletes the .md file
    -- After fix: automatically re-validates
    -- Toast: "Deleted N DB rows and N files, flushed N translations to disk"
    ensures: TranslationValidationScan
}

-- ─── Find duplicates view ──────────────────────────────────

-- Uses embedding vectors to find semantically similar posts.
-- Gate: requires semanticSimilarityEnabled in project metadata.
-- If disabled: shows "Semantic similarity is not enabled" message.

    exact_match: Boolean                  -- true if titles + content identical
}

-- Layout: header, count, paginated pair list (500 per page).
-- Each pair row: checkbox, post A title (clickable), arrow, post B title (clickable),
--   similarity badge ("Exact duplicate" or "N% similar"), Dismiss button.
-- Exact matches styled distinctly. Batch controls: Check All, Uncheck All,
--   Dismiss Checked (N). Refresh button.

rule DuplicateSearch {
    when: DuplicateSearchRequested()
    requires: semantic_similarity_enabled
    -- Loads USearch vector index for project
    -- For each indexed post: search 21 nearest neighbors
    -- similarity = max(0, 1 - distance)
    -- Filter: similarity >= threshold, exclude dismissed pairs
    -- For 100% embedding similarity: load post bodies, compare title+content
    --   If identical: exact_match = true
    -- Sort: exact matches first, then descending similarity
    ensures: DuplicateSearchResult
}

rule DuplicateDismiss {
    when: DuplicatePairDismissed(post_id_a, post_id_b)
    -- Inserts into dismissed_duplicate_pairs with canonical ID ordering
    -- Excluded from future searches

-- ─── Import analysis view ───────────────────────────────────

-- Editor for WXR (WordPress eXtended RSS) import definitions.
-- Keyed by import definition ID. Opened as always-pinned tab.
-- Workflow: Select File -> Analyze -> Resolve Conflicts -> Execute

-- Layout: header (definition name), file selector, analysis results,
--   conflict resolution panel, taxonomy mapping, execute button.

-- ─── Import analysis actions ────────────────────────────────

rule ImportSelectAndAnalyze {
    when: ImportAnalyzeRequested(definition_id, file_path)
    -- Parses WXR XML file
    -- Extracts: posts, pages, media, tags, categories, authors
    -- Shows summary counts per entity type
    -- Identifies conflicts: duplicate slugs, existing categories/tags
}

-- Conflict resolution:
--   Per-item dropdown: Import (create new), Skip (ignore), Merge (combine)
--   Default: Import for new items, Skip for existing matches

-- Taxonomy mapping:
--   Source categories/tags mapped to existing project categories/tags
--   Dropdown per source taxonomy term -> target term or "Create New"
--   AI taxonomy analysis (optional):
--     Gate: airplane mode check
--     Suggests mappings based on name similarity via title model

rule ImportExecute {
    when: ImportExecuteRequested(definition_id)
    -- No confirmation dialog — executes immediately
    -- Processes items per conflict resolution settings
    -- Creates posts, media, tags, categories as needed
