-- allium: 1
-- bDS Action Patterns and Chains
-- Scope: cross-cutting (all waves)
-- Distilled from: PostEditor.tsx, MediaEditor.tsx, appStore.ts
-- Cross-cutting patterns for AI operations, auto-translation,
-- drag-and-drop chains, and confirmation dialogs.
use "./post.allium" as post
use "./media.allium" as media
-- ─── External surfaces ──────────────────────────────────────
surface UserAction {
provides: AISuggestionRequested(entity_type, entity_id)
provides: PostSaved(post_id)
provides: PostAutoTranslateCompleted(post_id, language)
}
-- ─── AI operation gating ───────────────────────────────
invariant AIOperationGating {
-- All AI operations route through the active endpoint for the current mode.
-- See ai.allium AirplaneModeGating for endpoint selection logic.
-- If airplane_mode: use airplane endpoint (local model, e.g. Ollama/LM Studio)
-- If online: use online endpoint (cloud provider)
-- If active endpoint not configured: show toast, abort operation
-- Two model categories:
-- Title model: text analysis (suggestions, translation, language detect)
-- Image model: vision-capable (image analysis only)
-- Model selection: per-operation default from settings,
-- overrideable per-conversation in chat panel only
}
-- ─── AI suggestions pattern ────────────────────────────
-- Shared flow used by PostAIAnalysis and MediaAIImageAnalysis.
-- See modals.allium AISuggestionsModal value type.
rule AISuggestionFlow {
when: AISuggestionRequested(entity_type, entity_id)
-- 1. Check AIOperationGating (abort if offline and no local model)
-- 2. Send request to appropriate model:
-- Posts: title model, input = title + excerpt + first 2000 chars
-- Media: image model, input = 448x448 AI thumbnail JPEG
-- 3. Parse response into per-field suggestions
-- 4. Open AISuggestionsModal:
-- Each field: label, current value, suggested value, accept checkbox
-- Accept checkboxes default to true
-- Special case: post slug locked (no checkbox) if ever published
-- 5. On Confirm: apply only accepted fields to entity
-- Posts: triggers auto-save (3s timer reset)
-- Media: triggers explicit save
-- 6. On Cancel: discard all suggestions, no changes
}
-- ─── Auto-translation chain ────────────────────────────
rule AutoTranslationChain {
when: PostSaved(post_id)
-- Gate: AIOperationGating + post.doNotTranslate must be false
-- Triggered after any post save (auto-save, manual Ctrl+S, or unmount)
-- For each configured blogLanguage missing a translation for this post:
-- 1. Enqueue background task: translate metadata (title, excerpt)
-- via title model
-- 2. Enqueue background task: translate content (full markdown)
-- via title model
-- 3. Create/update translation record in DB
-- Tasks: sequential per language, parallel across languages
-- Progress visible in Tasks panel
}
rule MediaMetadataTranslationCascade {
when: PostAutoTranslateCompleted(post_id, language)
-- After a post translation completes for a given language:
-- For each media item linked to this post:
-- If media has source language set
-- and no translation exists for {language}:
-- Enqueue background task: translate media metadata
-- (title, alt, caption) via title model
-- Creates translated sidecar file: {path}.{lang}.meta
}
-- ─── Drag-and-drop image chain ─────────────────────────
-- Full chain when image file is dropped on post editor body.
-- See editor_post.allium PostDragDropImage for trigger rule.
-- Synchronous steps (user waits):
-- 1. importMedia(file) -> new media record + file copy + base sidecar
-- 2. generateThumbnails(media) -> async start (small/medium/large/ai)
-- 3. linkMediaToPost(media, post) -> update sidecar linkedPostIds
-- 4. insertMarkdownImage(cursor) -> insert ![](bds-media://id) at cursor
-- Background steps (non-blocking, results auto-applied):
-- 5. If AI available: aiImageAnalysis(media)
-- Uses image model on 448x448 AI thumbnail
-- Results auto-applied to media metadata (NO modal for drag-drop,
-- unlike manual Quick Action which shows AISuggestionsModal)
-- Triggers sidecar rewrite
-- 6. If auto-translate enabled (post.doNotTranslate=false):
-- For each blogLanguage: translateMediaMetadata(media, lang)
-- Creates translated sidecar files
-- ─── Confirmation dialog patterns ──────────────────────
-- Four distinct patterns used across the application:
-- Pattern 1: System confirm dialog
-- Simple yes/no system dialog, no custom UI
-- Used by: PostDelete, PostDiscard, TemplateDelete (when references exist)
-- Pattern 2: ConfirmDeleteModal (custom modal with reference info)
-- Shows entity name, reference counts, linked entity list
-- Two buttons: Cancel, Delete (destructive red style)
-- Used by: MediaDelete (shows linked posts), TagDelete (shows post count)
-- Pattern 3: ConfirmDialog (custom modal for non-delete confirmations)
-- Shows description of action and consequences
-- Two buttons: Cancel, Confirm
-- Used by: TagMerge ("Merge N tags into {target}? Cannot be undone.")
-- Pattern 4: No confirmation (immediate execution)
-- Action executes on click, no dialog
-- Used by: all Rebuild operations, ScriptDelete, MenuItemDelete,
-- MetadataDiff per-field sync, ImportExecute, MediaTranslationDelete,
-- MediaUnlink
