Entered plan mode. You should now focus on exploring the codebase and designing an implementation approach.

In plan mode, you should:
1. Thoroughly explore the codebase to understand existing patterns
2. Identify similar features and architectural approaches
3. Consider multiple approaches and their trade-offs
4. Use AskUserQuestion if you need to clarify the approach
5. Design a concrete implementation strategy
6. When ready, use ExitPlanMode to present your plan for approval

Remember: DO NOT write or edit any files yet. This is a read-only exploration and planning phase.

    "text": "Excellent! Now I have comprehensive information. Let me compile my findings into a clear report.\n\n## Summary\n\nI've thoroughly explored the Sensei codebase to understand the Article, ImageBlock, and Image data structures. Here are my findings:\n\n### 1. Article Data Type and JSON Serialization\n\n**Location:** `/Users/arnaud/projects/sensei/src/Sensei/Article.hs`\n\nThe `Article` type is a sum type with three constructors representing different article operations:\n\n```haskell\ndata Article\n  = PublishArticle\n      { _articleUser :: Text,\n        _articleTimestamp :: UTCTime,\n        _articleDir :: Text,\n        _article :: Text,\n        _articleDate :: Maybe UTCTime\n      }\n  | UpdateArticle\n      { _articleUser :: Text,\n        _articleTimestamp :: UTCTime,\n        _articleDir :: Text,\n        _articleRkey :: Text, -- TID/rkey portion only\n        _article :: Text,\n        _articleDate :: Maybe UTCTime\n      }\n  | DeleteArticle\n      { _articleUser :: Text,\n        _articleTimestamp :: UTCTime,\n        _articleDir :: Text,\n        _articleRkey :: Text -- TID/rkey portion only\n      }\n  deriving (Eq, Show, Generic)\n```\n\n**Fields:**\n- `_articleUser`: Username/identifier for the article author\n- `_articleTimestamp`: Server timestamp when the operation occurred\n- `_articleDir`: Directory context (appears to be workspace/location)\n- `_article`: The actual article content (markdown text)\n- `_articleRkey`: TID/record key for Update and Delete operations\n- `_articleDate`: Optional publication date (CLI override or frontmatter)\n\n**JSON Serialization:** Custom `ToJSON`/`FromJSON` instances using an `\"operation\"` discriminator field with values `\"PublishArticle\"`, `\"UpdateArticle\"`, or `\"DeleteArticle\"`.\n\n**Version Compatibility:** The `parseArticleJSON` function handles version 12 and later, defaulting `articleDate` to `Nothing` for version 12.\n\n### 2. ImageBlock and Image Data Structures\n\n**Location:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet.hs` (lines 342, 440-444)\n\nBoth are **minimally implemented** as placeholders:\n\n```haskell\n-- | Image block\n-- Lexicon: [pub.leaflet.blocks.image](https://tangled.org/leaflet.pub/leaflet/blob/main/lexicons/pub/leaflet/blocks/image.json)\ndata Image = Image\n  deriving stock (Eq, Show, Generic)\n  deriving anyclass (ToJSON, FromJSON)\n```\n\n**Current state:**\n- `Image` is a unit type (no fields defined yet)\n- `ImageBlock Image` is one constructor of the `BlockVariant` union type\n- Both derive generic `ToJSON`/`FromJSON` instances\n- The parsing in `BlockVariant` has a TODO placeholder (line 326):\n  ```haskell\n  \"pub.leaflet.blocks.image\" -> pure $ ImageBlock Image -- TODO\n  ```\n\n### 3. Blob-Related Data Structures\n\n**Locations:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet.hs` (lines 68-114) and `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Core.hs` (lines 171-205)\n\nTwo blob implementations exist:\n\n**Leaflet Blob (for Leaflet protocol):**\n```haskell\ndata Blob = Blob\n  { -- | MIME type of the blob content\n    mimeType :: Text,\n    -- | Size of the blob in bytes\n    size :: Int,\n    -- | CID reference to the blob content\n    ref :: BlobRef\n  }\n  deriving stock (Eq, Show, Generic)\n\nnewtype BlobRef = BlobRef {link :: CID}\n  deriving stock (Eq, Show, Generic)\n```\n\n**Core Bsky Blob (for AT Protocol):**\n```haskell\ndata BlobMetadata = BlobMetadata\n  { blobType :: Text, -- Always \"blob\"\n    blobRef :: Text, -- CID reference\n    blobMimeType :: Text,\n    blobSize :: Int\n  }\n  deriving stock (Eq, Show, Generic)\n```\n\n### 4. CID (Content Identifier) Implementation\n\n**Location:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky/CID.hs`\n\n```haskell\nnewtype CID = CID ByteString\n  deriving (Eq, Show)\n\n-- | Compute a CIDv1 for the given binary data\n-- Uses raw codec and SHA-256 hash\ncomputeCID :: ByteString -> CID\n\n-- | Convert CID to text representation using base32 encoding\ncidToText :: CID -> Text\n\n-- | Parse CID from text representation\ntextToCID :: Text -> Either String CID\n```\n\nCIDv1 format: `<multibase-prefix><version><multicodec><multihash>` with:\n- Multibase prefix: `'b'` (base32 lowercase)\n- Codec: raw binary (0x55)\n- Hash: SHA-256 (0x12)\n\n### 5. Article Generators for Testing\n\n**Location:** `/Users/arnaud/projects/sensei/test/Sensei/Generators.hs` (lines 209-233)\n\n```haskell\ngenerateArticle :: UTCTime -> Integer -> Gen Article\ngenerateArticle baseTime k = do\n  let st = shiftTime baseTime k\n  dir <- generateDir\n  title <- pack <$> arbitrary\n  content <- pack <$> arbitrary\n  date <- oneof [pure Nothing, Just <$> generateDate]\n  let articleContent = \"# \" <> title <> \"\\n\\n\" <> content\n  frequency\n    [ (5, pure $ PublishArticle \"arnaud\" st dir articleContent date),\n      (3, do\n          tidStr <- pack . take 13 <$> arbitrary\n          pure $ UpdateArticle \"arnaud\" st dir tidStr articleContent date),\n      (2, do\n          tidStr <- pack . take 13 <$> arbitrary\n          pure $ DeleteArticle \"arnaud\" st dir tidStr)\n    ]\n```\n\n**Notes:**\n- Generates markdown with simple format: `\"# \" <> title <> \"\\n\\n\" <> content`\n- Has TODO comment about generating proper markdown\n- Generates random TID-like strings (13 characters) for Update/Delete operations\n- Currently no support for image content or blocks\n\n### 6. Lexicon Specifications\n\nThe code references AT Protocol lexicons from the Leaflet.pub project:\n\n- **Document:** `pub.leaflet.document` \n- **LinearDocument:** `pub.leaflet.pages.linearDocument`\n- **Image Block:** `pub.leaflet.blocks.image`\n- **Text Block:** `pub.leaflet.blocks.text`\n\nAll reference comments point to official lexicon definitions at:\n```\nhttps://tangled.org/leaflet.pub/leaflet/blob/main/lexicons/pub/leaflet/blocks/image.json\n```\n\n### 7. Image Support Status\n\nThe test file `/Users/arnaud/projects/sensei/test/Sensei/Bsky/LeafletSpec.hs` has a pending test for image support (line 514-524):\n\n```haskell\nit \"converts markdown with images\" $ do\n  let markdown =\n        Text.unlines\n          [ \"First line of the document\",\n            \"![some image](https://some.image/source.png)\",\n            \"Third line with some text\"\n          ]\n  result <- mkMarkdownDocument markdown\n  case result of\n    Right LinearDocument {blocks = [_firstTextBlock, _imageBlock, _secondTextBlock]} -> pending\n    _ -> error \"Expected image block\"\n```\n\nThis test is **not yet implemented** - it's pending, indicating that markdown-to-image block conversion is a known missing feature.\n\n### Key Findings Summary\n\n1. **Article** is fully implemented with proper JSON serialization for Publish/Update/Delete operations\n2. **Image** and **ImageBlock** are completely stubbed out (unit type, no fields)\n3. **Blob** structures exist but Image doesn't use them yet\n4. **CID** implementation is complete and functional using SHA-256 hashing\n5. Markdown image parsing is recognized as a TODO/pending feature\n6. The codebase is structured for Leaflet.pub and AT Protocol integration but image support is incomplete"

    "text": "Perfect! Now I have all the information needed. Let me compile a comprehensive report on the publishArticle and updateArticle flow.\n\n## Complete Flow Analysis: publishArticle and updateArticle\n\nBased on my exploration of the codebase, here's a comprehensive breakdown of how articles are published and updated:\n\n---\n\n### 1. FUNCTION DEFINITIONS\n\n**File: `/Users/arnaud/projects/sensei/src/Sensei/Bsky.hs`**\n\n- **publishArticle** (lines 382-443): Publishes a new article to Bluesky as a Leaflet document\n- **updateArticle** (lines 445-505): Updates an existing article via its TID/rkey\n\n### 2. MARKDOWN TO ARTICLE CONVERSION FLOW\n\nThe conversion pipeline is:\n\n```\nMarkdown File (input)\n  ↓\nextractMetadata() - Extract YAML frontmatter\n  ├─ Extracts metadata like \"title\", \"description\", \"date\"\n  └─ Returns (metadata: [(Text, Text)], body: Text)\n  ↓\nmkMarkdownDocument() - Convert markdown body to LinearDocument\n  ├─ Parses markdown using CommonMark spec\n  ├─ Converts to AST with custom [Inline] and [BlockVariant] types\n  ├─ Extracts facets (formatting like bold, italic, links)\n  ├─ Generates unique TID for document\n  └─ Returns LinearDocument { id: TID, blocks: [Block] }\n  ↓\nDocument structure assembly\n  ├─ title: extracted from metadata \"title\" field\n  ├─ description: from metadata \"description\" field\n  ├─ author: userDID from BskyBackend\n  ├─ pages: [Linear linearDoc]\n  ├─ publication: publicationId from BskyBackend\n  ├─ publishedAt: ISO8601 formatted timestamp\n  └─ other fields: tags, theme, postRef (optional)\n  ↓\nBskyRecord Document - Wrapped for API submission\n  ├─ repo: author's BskyHandle\n  ├─ collection: \"pub.leaflet.document\" type\n  ├─ rkey: TID (for publish) or provided TID (for update)\n  └─ record: the Document\n  ↓\nBluesky PDS API\n  ├─ POST to com.atproto.repo.createRecord (publish)\n  └─ POST to com.atproto.repo.putRecord (update)\n```\n\n**Key Files:**\n- **Markdown parsing:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet/Markdown.hs` (lines 46-94)\n- **Metadata extraction:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet/Markdown.hs` (lines 49-74)\n- **Document structure:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet.hs` (lines 138-195)\n\n### 3. UPLOADBLOB FUNCTION STATUS\n\n**YES, uploadBlob is implemented!**\n\n**Location:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky.hs` (lines 189-192)\n\n```haskell\nbskyUploadBlob ::\n  BS.ByteString ->\n  ClientMonad BskyClientConfig BlobUploadResponse\nbskyUploadBlob = clientIn (Proxy @UploadBlob) Proxy\n```\n\n**API Definition:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky.hs` (lines 145-149)\n\n```haskell\ntype UploadBlob =\n  \"xrpc\"\n    :> \"com.atproto.repo.uploadBlob\"\n    :> ReqBody '[OctetStream] BS.ByteString\n    :> Post '[JSON] BlobUploadResponse\n```\n\n**Response Type:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Core.hs` (lines 171-205)\n\n```haskell\ndata BlobUploadResponse = BlobUploadResponse\n  { blob :: BlobMetadata\n  }\n\ndata BlobMetadata = BlobMetadata\n  { blobType :: Text,\n    blobRef :: Text,        -- CID reference\n    blobMimeType :: Text,\n    blobSize :: Int\n  }\n```\n\n**Integrated into BskyNet abstraction:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky.hs` (lines 279-282)\n\n```haskell\ndoUploadBlob ::\n  BskyClientConfig ->\n  BS.ByteString ->\n  m BlobUploadResponse,\n```\n\n**NOTE:** uploadBlob is NOT currently used in the article publishing flow. It exists as infrastructure but needs integration for image/media handling.\n\n### 4. COMPLETE FLOW: CLI TO BLUESKY PUBLICATION\n\n**Entry Point - CLI Parsing:**\n**File:** `/Users/arnaud/projects/sensei/src/Sensei/CLI/Options.hs` (lines 533-575)\n\n```haskell\npublishArticleParser :: Parser ArticleOptions\nupdateArticleParser :: Parser ArticleOptions\n```\n\nSupports:\n- `--publish FILE` / `-a FILE`: Publish article from file\n- `--update TID --file FILE` / `-u TID -f FILE`: Update existing article\n- `--date ISO8601_DATE` / `-d`: Optional publication date\n- `--delete TID` / `-D`: Delete article\n- `--list` / `-l`: List articles (not yet implemented)\n\n**Step 1 - Article Event Creation:**\n**File:** `/Users/arnaud/projects/sensei/src/Sensei/CLI.hs` (lines 200-207)\n\n```haskell\nep config (ArticleOptions (PublishArticle filePath customDate)) = do\n  article <- Text.readFile filePath  -- Read markdown file\n  send config $ postEventC (UserName userName) \n    [EventArticle $ Article.PublishArticle userName timestamp currentDir article customDate]\n\nep config (ArticleOptions (UpdateArticle rkey filePath customDate)) = do\n  content <- Text.readFile filePath\n  send config $ postEventC (UserName userName) \n    [EventArticle $ Article.UpdateArticle userName timestamp currentDir rkey content customDate]\n```\n\n**Article Event Types:**\n**File:** `/Users/arnaud/projects/sensei/src/Sensei/Article.hs` (lines 23-45)\n\n```haskell\ndata Article\n  = PublishArticle\n      { _articleUser :: Text,\n        _articleTimestamp :: UTCTime,\n        _articleDir :: Text,\n        _article :: Text,              -- Raw markdown content\n        _articleDate :: Maybe UTCTime   -- Optional custom date\n      }\n  | UpdateArticle\n      { _articleUser :: Text,\n        _articleTimestamp :: UTCTime,\n        _articleDir :: Text,\n        _articleRkey :: Text,          -- TID/rkey of article to update\n        _article :: Text,\n        _articleDate :: Maybe UTCTime\n      }\n  | DeleteArticle\n      { _articleUser :: Text,\n        _articleTimestamp :: UTCTime,\n        _articleDir :: Text,\n        _articleRkey :: Text           -- TID to delete\n      }\n```\n\n**Step 2 - Event Storage in Database:**\n**File:** `/Users/arnaud/projects/sensei/src/Sensei/DB/SQLite.hs` (lines 538-549)\n\nArticles with large content are stored specially:\n- Content is hashed and stored separately\n- Event stores the hash instead of full content\n- Content restored on retrieval via `restoreArticleContent`\n\n**Step 3 - Backend Event Handling:**\n**File:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky.hs` (lines 538-635)\n\nThe `bskyEventHandler` function processes events:\n\n**For PublishArticle (lines 545-564):**\n1. Extracts metadata from article content\n2. Gets authenticated session (with auto-refresh)\n3. Calls `publishArticle doCreateRecord backend session articleOp`\n4. Logs result (ArticlePublished or ArticlePublishFailed)\n\n**For UpdateArticle (lines 565-595):**\n1. Extracts metadata and metadata date\n2. Gets authenticated session\n3. Parses TID from rkey text\n4. Calls `updateArticle doPutRecord backend session articleTid articleOp`\n5. Logs result (ArticleUpdated or ArticleUpdateFailed)\n\n**For DeleteArticle (lines 596-634):**\n1. Gets authenticated session\n2. Parses TID from rkey\n3. Calls `doDeleteRecord` via BskyRecord\n4. Logs result (ArticleDeleted or ArticleDeleteFailed)\n\n### 5. DETAILED PUBLICATION DATE HANDLING\n\n**File:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky.hs` (lines 355-374)\n\nDate precedence (in order):\n1. **CLI option** (via `-d` flag in ArticleOptions)\n2. **Metadata date field** (from YAML frontmatter \"date\" key)\n3. **Current time** (fallback)\n\nParsed as ISO8601 with two formats:\n- `YYYY-MM-DD` (date only)\n- `YYYY-MM-DDTHH:MM:SSZ` (full ISO8601)\n\n### 6. AUTHENTICATION FLOW\n\n**File:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky.hs` (lines 310-353)\n\nSession management handles three cases:\n1. **No session**: Login with credentials → store in TVar\n2. **Valid session**: Return existing session\n3. **Expired session**: Refresh token → update stored session\n\nToken validation:\n- Decodes Base64-encoded JWT claims\n- Checks expiration against current time\n- Auto-refreshes if expired\n\n### 7. IMAGE/MEDIA HANDLING STATUS\n\n**Current State: NOT IMPLEMENTED in article flow**\n\nInfrastructure exists:\n- `bskyUploadBlob` function available for uploading binary data\n- `BlobMetadata` type with CID reference support\n- `Blob` type in Leaflet structure for embedding references\n\n**Missing integrations:**\n- No image parsing in markdown conversion\n- No automatic blob upload when markdown contains image references\n- No mechanism to replace markdown image syntax with blob references\n\n### 8. SUPPORTED MARKDOWN FEATURES\n\n**File:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet/Markdown.hs`\n\nFully supported:\n- **Text blocks** with facets (plaintext + formatting metadata)\n- **Headers** (all levels with facet support)\n- **Blockquotes** with nested facets\n- **Code blocks** with language specification\n- **Unordered lists** with items\n- **Inline formatting**: \n  - Bold (`**text**`)\n  - Italic (`*text*`)\n  - Code (`` `text` ``)\n  - Links (`[text](uri)`)\n\nPartially supported:\n- Math blocks (treated as plain text with Code facet)\n\nNot supported:\n- Images (treated as undefined)\n- Inline HTML\n- Reference link definitions\n- Thematic breaks\n\n### 9. METADATA FRONTMATTER FORMAT\n\n**Supported fields** (from YAML frontmatter):\n- `title`: Document title (max 1280 chars)\n- `description`: Document description (max 3000 chars)\n- `date`: Publication date (ISO8601 format)\n\n**Example:**\n```yaml\n---\ntitle: My Article\ndescription: A brief description\ndate: 2025-12-31\n---\n\n# Article body in markdown...\n```\n\n### 10. DOCUMENT STRUCTURE IN LEAFLET FORMAT\n\nThe final Document sent to Bluesky contains:\n- **$type**: \"pub.leaflet.document\" (identifier)\n- **title**: From metadata or empty\n- **description**: From metadata (optional)\n- **author**: User's DID\n- **pages**: Array with LinearDocument containing blocks\n- **publishedAt**: ISO8601 timestamp\n- **publication**: Publication ID from BskyBackend config\n- **tags**: Optional array of tags\n- **theme**: Optional theme configuration\n- **postRef**: Optional reference to associated post\n\n---\n\n## Summary: Complete Publication Pipeline\n\n1. **User inputs:** `ep publish article.md` or `ep update TID -f article.md`\n2. **CLI parsing:** Extracts file path and optional date\n3. **File reading:** Loads markdown from disk\n4. **Event creation:** Creates EventArticle with metadata\n5. **Database storage:** Stores article content (with hashing for large articles)\n6. **Backend handling:** Bsky event handler processes article event\n7. **Authentication:** Ensures valid Bluesky session (with auto-refresh)\n8. **Markdown conversion:** Extracts metadata + converts markdown to LinearDocument\n9. **Document assembly:** Builds Leaflet Document structure with all metadata\n10. **API submission:** Sends to Bluesky PDS (createRecord or putRecord)\n11. **Logging:** Records success/failure in event log\n\nThe system is production-ready for text-based articles but lacks image/media embedding until `bskyUploadBlob` integration is completed."

    "text": "Excellent! Now I have all the information I need. Let me compile my findings into a comprehensive report.\n\n## Markdown Parser Implementation in Sensei - Analysis Report\n\nBased on my exploration of the codebase, here's the complete understanding of the Markdown parser implementation:\n\n### 1. Location and Main Entry Points\n\n**Primary Module:**\n- `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet/Markdown.hs`\n\n**Related Data Structures:**\n- `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet.hs`\n\n**Command-line Tool:**\n- `/Users/arnaud/projects/sensei/app/md2leaflet.hs` (added in commit ec7d635)\n\n### 2. Inline Data Type and Parsing\n\nThe `Inline` type is defined as:\n\n```haskell\ndata Inline = Plain Text | Decorated Feature (Maybe SourceRange)\n  deriving (Eq, Show)\n```\n\nThere are two variants:\n- **Plain Text**: Regular plaintext content\n- **Decorated**: Text with formatting (bold, italic, links, code) plus optional source range for position tracking\n\nThe `IsInline` instance (lines 116-127) handles inline parsing:\n\n```haskell\ninstance IsInline [Inline] where\n  lineBreak = [Plain \"\\n\"]\n  softBreak = [Plain \"\\n\"]\n  str = singleton . Plain\n  entity = undefined              -- UNIMPLEMENTED\n  escapedChar = undefined         -- UNIMPLEMENTED\n  emph inl = inl <> [Decorated Italic Nothing]\n  strong inl = inl <> [Decorated Bold Nothing]\n  link uri title inl = inl <> [Plain title, Decorated (Link uri) Nothing]\n  image = undefined               -- UNIMPLEMENTED (placeholder line 125)\n  code txt = [Plain txt, Decorated Code Nothing]\n  rawInline = undefined           -- UNIMPLEMENTED\n```\n\n**Currently Parsed Inline Elements:**\n- Line breaks and soft breaks\n- Plain text strings\n- Emphasis (italic)\n- Strong (bold)\n- Links (with URI)\n- Inline code\n\n**Unimplemented Functions:**\n- `entity` - HTML entities\n- `escapedChar` - Escaped characters\n- `image` - Image parsing (uses `undefined`)\n- `rawInline` - Raw HTML inline content\n\n### 3. Block Elements Definition and Processing\n\nThe `BlockVariant` type (from Leaflet.hs, lines 293-309) defines supported blocks:\n\n```haskell\ndata BlockVariant\n  = IframeBlock Iframe\n  | TextBlock RichText           -- pub.leaflet.blocks.text\n  | BlockquoteBlock Blockquote   -- pub.leaflet.blocks.blockquote\n  | HeaderBlock Header           -- pub.leaflet.blocks.header\n  | ImageBlock Image             -- pub.leaflet.blocks.image\n  | UnorderedListBlock UnorderedList -- pub.leaflet.blocks.unorderedList\n  | WebsiteBlock Website\n  | MathBlock Math\n  | CodeBlock CodeBlock'         -- pub.leaflet.blocks.code\n  | HorizontalRuleBlock HorizontalRule\n  | BskyPostBlock BskyPost'\n  | PageBlock PageBlock'\n  | PollBlock Poll\n  | ButtonBlock Button\n```\n\nThe `IsBlock` instance (lines 139-168) defines how markdown blocks are converted:\n\n```haskell\ninstance IsBlock [Inline] [BlockVariant] where\n  paragraph inlines = [TextBlock RichText {plaintext, facets}]\n    where\n      (facets, plaintext) = extractFacets inlines\n  \n  plain inlines = [TextBlock RichText {plaintext, facets}]\n    where\n      (facets, plaintext) = extractFacets inlines\n  \n  thematicBreak = []  -- Horizontal rules are dropped\n  \n  blockQuote blocks =\n    [BlockquoteBlock Blockquote {plaintext, facets}]\n    where\n      (facets, plaintext) = extractBlockContent blocks\n  \n  codeBlock lang plaintext =\n    [CodeBlock CodeBlock' {language = Just lang, plaintext, syntaxHighlightingTheme = Nothing}]\n  \n  heading level inlines = [HeaderBlock Header {level, facets, plaintext}]\n    where\n      (facets, plaintext) = extractFacets inlines\n  \n  rawBlock = undefined              -- UNIMPLEMENTED\n  referenceLinkDefinition = undefined -- UNIMPLEMENTED\n  \n  list _ _spacing items =\n    [UnorderedListBlock $ UnorderedList {children = concatMap (mapMaybe (mkListItem . adjustFacet)) items}]\n```\n\n**Currently Supported Blocks:**\n- Paragraphs\n- Headers (with level)\n- Blockquotes\n- Code blocks (with language)\n- Unordered lists\n- Math (via mathSpec)\n\n**Processing Notes:**\n- Thematic breaks (horizontal rules) are parsed but dropped (empty list)\n- List items are adjusted with `adjustFacet` to correct byte positions\n- Facet byte ranges are calculated from source positions and adjusted for markup characters\n\n### 4. Image Parsing\n\n**Location of undefined function:** Line 125 in `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet/Markdown.hs`\n\n```haskell\nimage = undefined\n```\n\nThe `image` function signature from the commonmark library is:\n```haskell\nimage :: uri -> title -> [inl] -> inl\n```\n\nCurrently, there is no implementation. The parser will throw a runtime error if an image is encountered in markdown. To implement it properly, you would need to:\n1. Parse image URIs and alt text\n2. Create an `ImageBlock` from the Leaflet `BlockVariant` type\n3. Potentially handle blob uploads for local images\n\n### 5. LinearDocument Structure\n\n**Location:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet.hs` (lines 218-241)\n\n```haskell\ndata LinearDocument = LinearDocument\n  { id :: Maybe TID,        -- Optional document ID (TIDv7)\n    blocks :: [Block]       -- Required: Array of content blocks\n  }\n```\n\nEach `Block` contains:\n\n```haskell\ndata Block = Block\n  { block :: BlockVariant,            -- The actual content\n    alignment :: Maybe TextAlignment  -- Optional text alignment\n  }\n```\n\n**Supported Text Alignments:**\n```haskell\ndata TextAlignment\n  = TextAlignLeft\n  | TextAlignCenter\n  | TextAlignRight\n  | TextAlignJustify\n```\n\n### 6. Facet System for Text Formatting\n\nThe parser converts markdown formatting into a facet-based system. Each facet marks a byte range with formatting features:\n\n```haskell\ndata Facet = Facet\n  { index :: ByteSlice,      -- Byte range (zero-indexed, inclusive start, exclusive end)\n    features :: [Feature]    -- Formatting features applied\n  }\n\ndata Feature\n  = Link {uri :: Text}\n  | DidMention {did :: Text}\n  | AtMention {atURI :: Text}\n  | Code\n  | Highlight\n  | Underline\n  | Strikethrough\n  | Id {featureId :: Maybe Text}\n  | Bold\n  | Italic\n```\n\n### 7. Key Parsing Functions\n\n**Main entry point:**\n```haskell\nmkMarkdownDocument :: Text -> IO (Either String LinearDocument)\n```\nLocated at lines 77-88. Creates a document with:\n- Auto-generated TID\n- Parsed blocks from markdown\n- No alignment specified\n\n**Core parsing:**\n```haskell\nparseMarkdown :: Text -> Either String [Block]\nparseMarkdown txt =\n  bimap show (fmap (`Block` Nothing)) $\n    runIdentity $\n      parseCommonmarkWith (mathSpec <> defaultSyntaxSpec) (tokenize \"\" txt)\n```\nLocated at lines 90-94. Uses the commonmark library with:\n- Default CommonMark syntax\n- Math extension (for LaTeX equations)\n- No text alignment applied\n\n**Facet extraction:** \nFunctions `extractFacets` (lines 208-211) and `extractFacet` (lines 239-282) handle the complex conversion from source coordinates (character positions including markup) to plaintext byte positions, accounting for UTF-8 encoding.\n\n### 8. Special Features\n\n**YAML Frontmatter Support:**\n```haskell\nextractMetadata :: Text -> ([(Text, Text)], Text)\n```\n(Lines 49-74) Extracts key-value pairs from frontmatter delimited by `---`.\n\n**List Item Handling:**\nThe `adjustFacet` function (lines 170-178) corrects byte positions for list items to account for the 2-byte indentation (\"- \").\n\n**Math Support:**\nInline math via `inlineMath` and `displayMath` are currently mapped to code blocks as placeholders:\n```haskell\ninstance HasMath [Inline] where\n  inlineMath txt = [Plain txt, Decorated Code Nothing] -- TODO\n  displayMath txt = [Plain txt]  -- TODO\n```\n\n### 9. Sample Markdown File\n\nTest file at `/Users/arnaud/projects/sensei/test/sample-markdown.md` contains a French article about catamorphisms with:\n- YAML frontmatter (title, author, date)\n- Headers at multiple levels\n- Code blocks (Haskell and Java)\n- Blockquotes\n- Links\n- Inline formatting\n\n### 10. Command-line Tool\n\nThe `md2leaflet` executable (app/md2leaflet.hs) provides a simple CLI:\n```bash\nmd2leaflet [markdown-file]  # Reads from file\nmd2leaflet                  # Reads from stdin\n```\n\nOutputs JSON using `aeson-pretty` for readability.\n\n---\n\n**Summary of Unimplemented Elements:**\n- Image parsing (`image = undefined`)\n- HTML entities (`entity = undefined`)\n- Escaped characters (`escapedChar = undefined`)\n- Raw inline HTML (`rawInline = undefined`)\n- Raw blocks (`rawBlock = undefined`)\n- Reference link definitions (`referenceLinkDefinition = undefined`)\n- Math display formatting (currently treated as plain text)"

# pub.leaflet.blocks.image Lexicon Specification

## Main Object Structure

The primary definition contains two required fields:

**Required Fields:**
- `image`: A blob type accepting image files with a maximum size of 1,000,000 bytes
- `aspectRatio`: A reference to the aspectRatio object definition

**Optional Fields:**
- `alt`: A string field described as "Alt text description of the image, for accessibility."

## AspectRatio Nested Object

This referenced object defines image proportions with two required integer properties:

- `width`: Integer value (required)
- `height`: Integer value (required)

## Key Constraints

The image blob specifies `"accept": ["image/*"]`, restricting uploads to valid image file types. The 1MB size limitation ensures reasonable file management for the publishing platform. The aspectRatio object captures dimensional metadata without pixel specifications, allowing flexible scaling while maintaining proportional integrity.

The alt text field supports accessibility compliance by enabling descriptive image labeling, though it remains optional rather than mandatory in the schema definition.

    "text": "Perfect! Now I have a comprehensive understanding of the codebase. Let me create a detailed implementation plan.\n\n# Detailed Implementation Plan: Image Support for Markdown Articles in Sensei\n\n## Architecture Overview\n\nThe implementation spans four major areas:\n1. **Data structures** in `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet.hs`\n2. **Markdown parsing** in `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet/Markdown.hs`\n3. **Image resolution and upload** in `/Users/arnaud/projects/sensei/src/Sensei/Bsky.hs`\n4. **Testing** in `/Users/arnaud/projects/sensei/test/Sensei/` (multiple files)\n\n---\n\n## Phase 1: Data Structures\n\n### 1.1 AspectRatio Type\n\n**Location:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet.hs` (after line 439)\n\n**Implementation:**\n```haskell\n-- | Aspect ratio for images\n-- Lexicon: pub.leaflet.blocks.image#aspectRatio\ndata AspectRatio = AspectRatio\n  { width :: Int   -- Required: Image width in pixels\n  , height :: Int  -- Required: Image height in pixels\n  }\n  deriving stock (Eq, Show, Generic)\n  deriving anyclass (ToJSON, FromJSON)\n```\n\n**Rationale:** Following the DuplicateRecordFields pattern used throughout the codebase (as specified in CLAUDE.md), we use simple field names `width` and `height`.\n\n### 1.2 Image Type Replacement\n\n**Location:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet.hs` (replace lines 440-444)\n\n**Implementation:**\n```haskell\n-- | Image block\n-- Lexicon: [pub.leaflet.blocks.image](https://tangled.org/leaflet.pub/leaflet/blob/main/lexicons/pub/leaflet/blocks/image.json)\ndata Image = Image\n  { image :: Blob              -- Required: Image blob (max 1MB, accept image/*)\n  , aspectRatio :: AspectRatio -- Required: Image dimensions\n  , alt :: Maybe Text          -- Optional: Alt text for accessibility\n  }\n  deriving stock (Eq, Show, Generic)\n```\n\n**Custom JSON instances required:**\n```haskell\ninstance ToJSON Image where\n  toJSON Image {image = img, aspectRatio, alt} =\n    object $\n      [ \"$type\" .= BskyType @(Lexicon Image),\n        \"image\" .= img,\n        \"aspectRatio\" .= aspectRatio\n      ]\n        <> optionalField \"alt\" alt\n\ninstance FromJSON Image where\n  parseJSON = withObject \"Image\" $ \\v -> do\n    _ <- v .: \"$type\" :: Parser Text\n    Image\n      <$> v .: \"image\"\n      <*> v .: \"aspectRatio\"\n      <*> v .:? \"alt\"\n```\n\n**Rationale:** Follows the exact same pattern as other block types (Header, RichText, Blockquote), using `$type` field and optional field helpers.\n\n### 1.3 Update BlockVariant ToJSON\n\n**Location:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet.hs` (line 318)\n\n**Change:**\n```haskell\ninstance ToJSON BlockVariant where\n  toJSON (TextBlock rt) = toJSON rt\n  toJSON (BlockquoteBlock bq) = toJSON bq\n  toJSON (HeaderBlock hdr) = toJSON hdr\n  toJSON (CodeBlock code) = toJSON code\n  toJSON (UnorderedListBlock list) = toJSON list\n  toJSON (ImageBlock img) = toJSON img  -- ADD THIS LINE\n  -- For now, other block types are not implemented\n  toJSON _ = object [\"$type\" .= (\"pub.leaflet.blocks.unknown\" :: Text)]\n```\n\n### 1.4 Update BlockVariant FromJSON\n\n**Location:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet.hs` (line 326)\n\n**Change:**\n```haskell\ninstance FromJSON BlockVariant where\n  parseJSON = withObject \"BlockVariant\" $ \\v -> do\n    typ <- v .: \"$type\" :: Parser Text\n    case typ of\n      \"pub.leaflet.blocks.text\" -> TextBlock <$> parseJSON (Object v)\n      \"pub.leaflet.blocks.blockquote\" -> BlockquoteBlock <$> parseJSON (Object v)\n      \"pub.leaflet.blocks.image\" -> ImageBlock <$> parseJSON (Object v)  -- CHANGE THIS LINE\n      \"pub.leaflet.blocks.header\" -> HeaderBlock <$> parseJSON (Object v)\n      \"pub.leaflet.blocks.code\" -> CodeBlock <$> parseJSON (Object v)\n      \"pub.leaflet.blocks.unorderedList\" -> UnorderedListBlock <$> parseJSON (Object v)\n      _ -> fail $ \"Unsupported block type: \" ++ show typ\n```\n\n### 1.5 Update Module Exports\n\n**Location:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet.hs` (module header, typically around lines 1-20)\n\n**Add to exports:**\n```haskell\nmodule Sensei.Bsky.Leaflet \n  ( ...existing exports...\n  , AspectRatio(..)\n  , Image(..)\n  ) where\n```\n\n---\n\n## Phase 2: Markdown Parser\n\n### 2.1 Implement Image Inline Parser\n\n**Location:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet/Markdown.hs` (line 125)\n\n**Current issue:** `image = undefined` crashes on any image markdown.\n\n**Implementation approach:**\n\nSince CommonMark parses `![alt](url)` as an inline element but Leaflet requires block-level ImageBlock, we need to:\n1. Parse image as inline with placeholder data\n2. Post-process to lift images to block level\n\n**Step 2.1a: Create intermediate representation**\n\nAdd new Inline variant:\n```haskell\n-- Line 102, modify Inline type:\ndata Inline \n  = Plain Text \n  | Decorated Feature (Maybe SourceRange)\n  | ImageInline Text Text (Maybe SourceRange)  -- ADD: alt, url, range\n  deriving (Eq, Show)\n```\n\n**Step 2.1b: Implement image function**\n```haskell\n-- Line 125, replace undefined:\nimage url title inlines = \n  inlines <> [ImageInline title url Nothing]\n```\n\n**Rationale:** \n- `url` is the image source (local path or remote URL)\n- `title` is the alt text (in CommonMark, the text inside `[]`)\n- We store this as inline data that will be post-processed\n\n### 2.2 Handle ImageInline in Rangeable Instance\n\n**Location:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet/Markdown.hs` (line 109)\n\n```haskell\ninstance Rangeable Inline where\n  ranged range = \\case\n    Plain t -> Plain t\n    Decorated f _ -> Decorated f (Just range)\n    ImageInline alt url _ -> ImageInline alt url (Just range)  -- ADD\n```\n\n### 2.3 Update extractFacet to Handle Images\n\n**Location:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet/Markdown.hs` (line 240)\n\n```haskell\nextractFacet :: Inline -> Converter -> Converter\nextractFacet = \\case\n  Decorated f rge -> makeFacet f rge\n  ImageInline {} -> id  -- ADD: Images are ignored in inline context, handled in block lifting\n  Plain \"\\n\" -> \\Converter {facets, plaintext} ->\n    -- ...existing implementation...\n  Plain t -> \\Converter {plaintext, currentLinePlaintext, ..} ->\n    -- ...existing implementation...\n```\n\n### 2.4 Implement Image Lifting Post-Processor\n\n**Location:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet/Markdown.hs` (new function, add after `extractFacets` around line 211)\n\n**Function signature:**\n```haskell\n-- | Lift inline images to block-level ImageBlock elements\n-- This is needed because CommonMark parses images as inline elements,\n-- but Leaflet requires them as separate blocks.\n-- \n-- Strategy: When we encounter TextBlock containing ImageInline elements,\n-- we split it into:\n--   1. TextBlock before image (if any text exists)\n--   2. ImageBlock for the image (with placeholder data)\n--   3. Continue processing remaining inlines\nliftImagesToBlocks :: [BlockVariant] -> [BlockVariant]\n```\n\n**Implementation:**\n```haskell\nliftImagesToBlocks :: [BlockVariant] -> [BlockVariant]\nliftImagesToBlocks = concatMap processBlock\n  where\n    processBlock :: BlockVariant -> [BlockVariant]\n    processBlock (TextBlock rt) = \n      -- For text blocks, we need to check if there were any images\n      -- during parsing. However, images are currently lost in the \n      -- extractFacets process. We need a different approach.\n      [TextBlock rt]\n    processBlock other = [other]\n```\n\n**PROBLEM IDENTIFIED:** The current architecture loses image information when converting from `[Inline]` to `RichText` via `extractFacets`. We need to preserve image data.\n\n**REVISED APPROACH - Create parallel image extraction:**\n\n```haskell\n-- | Extract both facets AND images from inline list\nextractFacetsAndImages :: [Inline] -> (([Facet], Text), [ImageInline])\nextractFacetsAndImages inlines = \n  let Converter {facets, plaintext} = foldl (flip extractFacet) initialConverter (filter (not . isImage) inlines)\n      images = [img | ImageInline alt url rng <- inlines, let img = (alt, url, rng)]\n   in ((facets, plaintext), images)\n  where\n    isImage (ImageInline {}) = True\n    isImage _ = False\n```\n\n**Update IsBlock instance paragraph/plain:**\n\n**Location:** Line 140-146\n\n```haskell\ninstance IsBlock [Inline] [BlockVariant] where\n  paragraph inlines = \n    let ((facets, plaintext), images) = extractFacetsAndImages inlines\n        textBlock = if Text.null plaintext \n                    then [] \n                    else [TextBlock RichText {plaintext, facets}]\n        imageBlocks = map mkPlaceholderImage images\n     in textBlock <> imageBlocks\n\n  plain inlines =\n    let ((facets, plaintext), images) = extractFacetsAndImages inlines\n        textBlock = if Text.null plaintext \n                    then [] \n                    else [TextBlock RichText {plaintext, facets}]\n        imageBlocks = map mkPlaceholderImage images\n     in textBlock <> imageBlocks\n  \n  -- ... rest unchanged\n```\n\n**New helper function:**\n```haskell\n-- | Create placeholder ImageBlock that will be resolved later\n-- The image field contains a placeholder Blob with the URL in the mimeType\n-- This is a hack but allows us to preserve the URL through the parsing stage\nmkPlaceholderImage :: (Text, Text, Maybe SourceRange) -> BlockVariant\nmkPlaceholderImage (alt, url, _range) = \n  ImageBlock $ PlaceholderImage url (if Text.null alt then Nothing else Just alt)\n```\n\n**BETTER APPROACH - Create separate type for unresolved images:**\n\nAdd to `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet.hs`:\n\n```haskell\n-- | Unresolved image reference from markdown parsing\n-- Contains URL that needs to be fetched, decoded, and uploaded\ndata UnresolvedImage = UnresolvedImage\n  { imageSource :: Text      -- URL or file path\n  , imageAlt :: Maybe Text   -- Alt text from markdown\n  }\n  deriving stock (Eq, Show, Generic)\n  deriving anyclass (ToJSON, FromJSON)\n\n-- Extend BlockVariant:\ndata BlockVariant\n  = ...existing variants...\n  | UnresolvedImageBlock UnresolvedImage  -- ADD THIS\n```\n\nThen in markdown parser:\n```haskell\nmkPlaceholderImage :: (Text, Text, Maybe SourceRange) -> BlockVariant\nmkPlaceholderImage (alt, url, _range) = \n  UnresolvedImageBlock $ UnresolvedImage \n    { imageSource = url\n    , imageAlt = if Text.null alt then Nothing else Just alt\n    }\n```\n\n**Rationale:** This cleanly separates the parsing phase (creates UnresolvedImageBlock) from the resolution phase (converts to ImageBlock), following separation of concerns.\n\n---\n\n## Phase 3: Image Resolution\n\n### 3.1 New Module for Image Processing\n\n**Create:** `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Image.hs`\n\n**Purpose:** Encapsulate all image fetching, decoding, and aspect ratio computation.\n\n**Dependencies needed:**\n\nAdd to `sensei.cabal`

\"provides helpful error for corrupted images\" $ do\n      -- Create file with invalid image data\n      pending\n```\n\n---\n\n## Phase 5: Additional Considerations\n\n### 5.1 Base Directory Context for Relative Paths\n\n**Problem:** When markdown contains `![](./images/photo.png)`, we need to know the base directory.\n\n**Solution:** Extend Article type or pass context through publishing functions.\n\n**Location:** `/Users/arnaud/projects/sensei/src/Sensei/Article.hs` (check if exists) or `/Users/arnaud/projects/sensei/src/Sensei/Event.hs`\n\n**Option 1 - Add to Article:**\n```haskell\ndata Article \n  = PublishArticle \n      { article :: Text\n      , articleDate :: Maybe Date\n      , articleBasePath :: Maybe FilePath  -- ADD THIS\n      }\n  | UpdateArticle { ... }\n  | DeleteArticle { ... }\n```\n\n**Option 2 - Extract from file path:**\nIf articles are read from files, extract base directory from the file path in the CLI layer.\n\n### 5.2 Caching and Performance\n\n**Consideration:** Multiple identical images in same article shouldn't be uploaded multiple times.\n\n**Solution (future optimization):**\n- Compute hash of image bytes\n- Check if already uploaded (requires tracking uploaded blobs)\n- Reuse existing Blob reference\n\n**Not critical for MVP - can be added later.**\n\n### 5.3 Error Reporting to User\n\n**Location:** CLI layer (likely `/Users/arnaud/projects/sensei/src/Sensei/CLI.hs` or `/Users/arnaud/projects/sensei/app/sensei.hs`)\n\nWhen `publishArticle` returns `Left errorMsg`, ensure clear error messages:\n\n```haskell\ncase publishResult of\n  Left err | \"Failed to resolve images:\" `isPrefixOf` err -> do\n    putStrLn \"ERROR: Image resolution failed\"\n    putStrLn err\n    putStrLn \"\"\n    putStrLn \"Possible causes:\"\n    putStrLn \"  - Image file not found\"\n    putStrLn \"  - Image exceeds 1MB size limit\"\n    putStrLn \"  - Network error downloading remote image\"\n    putStrLn \"  - Invalid image format\"\n  Left err -> putStrLn $ \"ERROR: \" <> err\n  Right record -> putStrLn $ \"Published: \" <> show record\n```\n\n### 5.4 Logging\n\n**Location:** Image resolution function\n\nAdd logging using existing logger infrastructure:\n\n```haskell\nresolveAndUploadImage clientConfig baseDir source alt = do\n  logInfo $ \"Resolving image: \" <> source\n  resolved <- resolveImage baseDir source alt\n  logInfo $ \"Uploading image (\" <> Text.pack (show $ BS.length $ imageBytes resolved) <> \" bytes)\"\n  uploaded <- liftIO $ send clientConfig (bskyUploadBlob $ imageBytes resolved)\n  logInfo $ \"Image uploaded successfully: \" <> source\n  pure $ Image { ... }\n```\n\n---\n\n## Implementation Sequence\n\n### Step 1: Data Structures (Low Risk)\n1. Add AspectRatio type\n2. Implement Image type with JSON instances\n3. Add UnresolvedImage type\n4. Update BlockVariant ToJSON/FromJSON\n5. Add generators\n6. Run tests: `cabal test --test-options=\"--match 'Arbitrary.*Image'\"`\n\n### Step 2: Markdown Parser (Medium Risk)\n1. Add ImageInline to Inline type\n2. Implement image function\n3. Update Rangeable instance\n4. Implement extractFacetsAndImages\n5. Update paragraph/plain to create UnresolvedImageBlocks\n6. Run tests: `cabal test --test-options=\"--match 'LeafletSpec'\"`\n\n### Step 3: Image Resolution (High Risk - New Dependencies)\n1. Add JuicyPixels dependency to cabal file\n2. Create Image.hs module with types and error handling\n3. Implement detectMimeType\n4. Implement fetchImageBytes (file only first, then URL)\n5. Implement resolveImage\n6. Write unit tests\n7. Run tests: `cabal test --test-options=\"--match 'ImageSpec'\"`\n\n### Step 4: Integration (High Risk - External APIs)\n1. Implement resolveAndUploadImage\n2. Implement resolveDocumentImages\n3. Update publishArticle\n4. Update updateArticle\n5. Test with real markdown file (manual testing)\n\n### Step 5: Polish\n1. Add logging\n2. Improve error messages\n3. Add integration tests\n4. Update documentation\n\n---\n\n## Dependency Analysis\n\n### New Dependencies Required\n\n**Add to sensei.cabal:**\n```haskell\n  build-depends:\n    ...existing deps...\n    , JuicyPixels       -- BSD3 licensed, for image decoding\n```\n\n**Notes:**\n- `http-client` and `http-client-tls` already exist in dependencies (line 120-121)\n- `bytestring` already exists\n- `directory` already exists\n- No breaking changes to existing dependencies\n\n### Existing Dependencies Leveraged\n\n- `commonmark` and `commonmark-extensions` (already used for markdown)\n- `http-client` (already used, for remote images)\n- `aeson` (already used, for JSON)\n- `safe-exceptions` (already used, for error handling)\n\n---\n\n## Error Handling Strategy\n\n### Error Type Hierarchy\n\n```\nImageResolutionError (Exception)\n├── ImageNotFound Text\n├── ImageTooLarge Text Int\n├── ImageDownloadFailed Text Text\n├── ImageDecodeFailed Text Text\n└── InvalidImageSource Text\n```\n\n### Error Propagation\n\n```\nresolveImage :: m ResolvedImage\n  → throws ImageResolutionError\n\nresolveAndUploadImage :: m Image\n  → catches ImageResolutionError, converts to String\n  → propagates upload exceptions\n\nresolveDocumentImages :: m (Either String LinearDocument)\n  → catches all exceptions, returns Left\n\npublishArticle :: m (Either String Record)\n  → already returns Either, adds image errors to Left values\n```\n\n### User-Facing Errors\n\n**Good error message example:**\n```\nFailed to resolve images: Image too large: https://example.com/huge.png (2500000 bytes, max 1000000)\n\nFailed to resolve images: Image not found: ./images/photo.png\n\nFailed to resolve images: Image download failed: https://example.com/photo.png (Connection timeout)\n```\n\n---\n\n## Migration Considerations\n\n### Backward Compatibility\n\n**No breaking changes:**\n- Existing markdown without images works unchanged\n- UnresolvedImageBlock is internal representation only\n- Image type was stub before, now fully implemented\n- JSON serialization is new, no existing data to migrate\n\n### Forward Compatibility\n\n**Graceful degradation:**\n- If image upload fails, entire article publish fails (good - ensures data integrity)\n- Future: Could make images optional with flag to skip failed images\n\n---\n\n## Testing Checklist\n\n### Unit Tests\n- [ ] AspectRatio JSON roundtrip\n- [ ] Image JSON roundtrip with all fields\n- [ ] Image JSON roundtrip with minimal fields (no alt)\n- [ ] UnresolvedImage JSON roundtrip\n- [ ] detectMimeType for PNG, JPEG, GIF, WebP\n- [ ] fetchImageBytes for local files\n- [ ] fetchImageBytes for remote URLs\n- [ ] resolveImage validates size limit\n- [ ] resolveImage extracts correct dimensions\n\n### Parser Tests  \n- [ ] Single image in markdown\n- [ ] Multiple images in one paragraph\n- [ ] Image with alt text\n- [ ] Image without alt text\n- [ ] Image in blockquote\n- [ ] Image in list item\n- [ ] Mixed text and images\n\n### Integration Tests\n- [ ] Full flow: markdown → parse → resolve → upload → publish\n- [ ] Relative path resolution\n- [ ] Absolute path resolution\n- [ ] Remote URL resolution\n- [ ] Error handling: missing file\n- [ ] Error handling: oversized image\n- [ ] Error handling: invalid image format\n- [ ] Error handling: network failure\n\n### Manual Tests\n- [ ] Publish article with local image\n- [ ] Publish article with remote image\n- [ ] Publish article with mixed images\n- [ ] Update article with new images\n- [ ] Verify uploaded image appears correctly in Leaflet\n\n---\n\n## Risk Assessment\n\n### High Risk Areas\n\n1. **Image decoding dependency (JuicyPixels)**\n   - **Mitigation:** Well-established library, widely used\n   - **Fallback:** Could implement dimension extraction manually for common formats\n\n2. **Network failures for remote images**\n   - **Mitigation:** Comprehensive error handling with retries\n   - **Fallback:** Clear error messages guide users to fix issues\n\n3. **Markdown parser inline→block mismatch**\n   - **Mitigation:** UnresolvedImageBlock intermediate representation\n   - **Fallback:** Could parse markdown twice (once to extract images)\n\n### Medium Risk Areas\n\n1. **Size validation enforcement**\n   - **Mitigation:** Check before upload AND rely on server validation\n   \n2. **MIME type detection accuracy**\n   - **Mitigation:** Use magic number detection, fallback to extension-based\n\n### Low Risk Areas\n\n1. **JSON serialization** - Well-tested pattern\n2. **Blob upload** - Already implemented and working\n3. **Data structures** - Straightforward, no complex logic\n\n---\n\n## Performance Considerations\n\n### Current Implementation\n\n- **Image resolution:** Synchronous, blocks article publishing\n- **Multiple images:** Resolved sequentially, not in parallel\n- **No caching:** Same image uploaded multiple times if referenced multiple times\n\n### Future Optimizations (Post-MVP)\n\n1. **Parallel image resolution:**\n   ```haskell\n   resolvedBlocks <- traverse (async . resolveBlock) (blocks linearDoc)\n   blocks' <- traverse wait resolvedBlocks\n   ```\n\n2. **Image caching:**\n   ```haskell\n   type ImageCache = TVar (Map Text Blob)\n   -- Check cache before resolving/uploading\n   ```\n\n3. **Lazy loading:**\n   ```haskell\n   -- Return UnresolvedImageBlock in document, resolve on render\n   ```\n\n---\n\n### Critical Files for Implementation\n\nHere are the 5 most critical files for implementing this plan:\n\n- `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet.hs` - Core data structures (AspectRatio, Image, UnresolvedImage types; JSON instances; BlockVariant updates)\n\n- `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Leaflet/Markdown.hs` - Markdown parser modifications (ImageInline type; image function implementation; extractFacetsAndImages; UnresolvedImageBlock creation)\n\n- `/Users/arnaud/projects/sensei/src/Sensei/Bsky/Image.hs` - New module for image processing (resolveImage function; error types; image fetching, validation, and dimension extraction)\n\n- `/Users/arnaud/projects/sensei/src/Sensei/Bsky.hs` - Integration layer (resolveDocumentImages function; publishArticle/updateArticle modifications to resolve images before upload)\n\n- `/Users/arnaud/projects/sensei/test/Sensei/Bsky/LeafletSpec.hs` - Test coverage (update pending test; add comprehensive image parsing tests; verify UnresolvedImageBlock creation)"

     1→# Implementation Plan: Image Support in Markdown Articles
     2→
     3→## Goal
     4→Enable publishing and updating articles from markdown with embedded images, automatically uploading them as blobs to Bluesky PDS.
     5→
     6→## Overview
     7→1. Implement proper Image/ImageBlock/AspectRatio data structures per AT Protocol lexicon
     8→2. Fix markdown parser to handle `![alt](url)` syntax
     9→3. Resolve images (file/URL), compute aspect ratio, upload as blobs
    10→4. Comprehensive unit and integration testing
    11→
    12→---
    13→
    14→## Phase 1: Data Structures (Low Risk)
    15→
    16→### Files Modified
    17→- `src/Sensei/Bsky/Leaflet.hs`
    18→- `test/Sensei/Generators.hs`
    19→
    20→### Changes
    21→
    22→**1.1 Add AspectRatio type** (after line 439)
    23→```haskell
    24→data AspectRatio = AspectRatio
    25→  { width :: Int
    26→  , height :: Int
    27→  }
    28→  deriving stock (Eq, Show, Generic)
    29→  deriving anyclass (ToJSON, FromJSON)
    30→```
    31→
    32→**1.2 Replace Image stub** (lines 440-444)
    33→```haskell
    34→data Image = Image
    35→  { image :: Blob
    36→  , aspectRatio :: AspectRatio
    37→  , alt :: Maybe Text

    51→    _ <- v .: "$type"
    52→    Image <$> v .: "image" <*> v .: "aspectRatio" <*> v .:? "alt"
    53→```
    54→
    55→**1.3 Add UnresolvedImage type** (for markdown parsing phase)
    56→```haskell
    57→-- Unresolved image from markdown, needs fetching/upload
    58→data UnresolvedImage = UnresolvedImage
    59→  { imageSource :: Text      -- URL or file path
    60→  , imageAlt :: Maybe Text   -- Alt text
    61→  }
    62→  deriving stock (Eq, Show, Generic)
    63→  deriving anyclass (ToJSON, FromJSON)
    64→```
    65→
    66→**1.4 Extend BlockVariant** (line 293)
    67→```haskell
    68→data BlockVariant
    69→  = ...existing variants...
    70→  | UnresolvedImageBlock UnresolvedImage  -- ADD
    71→```
    72→
    73→**1.5 Update ToJSON/FromJSON** (lines 311-331)
    74→- Add `toJSON (ImageBlock img) = toJSON img` (line 318)
    75→- Change line 326: `"pub.leaflet.blocks.image" -> ImageBlock <$> parseJSON (Object v)`
    76→- Add UnresolvedImageBlock handling (internal only, not serialized to external JSON)
    77→
    78→**1.6 Update Generators**
    79→```haskell
    80→instance Arbitrary AspectRatio where
    81→  arbitrary = AspectRatio <$> choose (1, 4096) <*> choose (1, 4096)
    82→
    83→instance Arbitrary Image where
    84→  arbitrary = Image <$> arbitrary <*> arbitrary <*> arbitrary
    85→
    86→instance Arbitrary UnresolvedImage where
    87→  arbitrary = UnresolvedImage
    88→    <$> elements ["https://example.com/image.png", "/path/to/image.png"]
    89→    <*> arbitrary
    90→```
    91→
    92→### Testing
    93→- JSON roundtrip tests for AspectRatio, Image
    94→- QuickCheck property tests with generators
    95→
    96→---
    97→
    98→## Phase 2: Markdown Parser (Medium Risk)
    99→
   100→### Files Modified
   101→- `src/Sensei/Bsky/Leaflet/Markdown.hs`
   102→- `test/Sensei/Bsky/LeafletSpec.hs`
   103→
   104→### Key Challenge
   105→CommonMark parses `![alt](url)` as **inline** element, but Leaflet requires **block-level** ImageBlock.
   106→
   107→### Solution
   108→1. Parse images as new `ImageInline` variant
   109→2. In `paragraph`/`plain` handlers, separate images from text
   110→3. Create UnresolvedImageBlock for each image
   111→
   112→### Changes
   113→
   114→**2.1 Extend Inline type** (line 102)
   115→```haskell
   116→data Inline
   117→  = Plain Text
   118→  | Decorated Feature (Maybe SourceRange)
   119→  | ImageInline Text Text (Maybe SourceRange)  -- alt, url, range
   120→  deriving (Eq, Show)
   121→```
   122→
   123→**2.2 Implement image function** (line 125)
   124→```haskell
   125→image url title inlines = inlines <> [ImageInline title url Nothing]
   126→```
   127→
   128→**2.3 Update Rangeable instance** (line 109)
   129→```haskell
   130→ranged range = \case
   131→  Plain t -> Plain t
   132→  Decorated f _ -> Decorated f (Just range)
   133→  ImageInline alt url _ -> ImageInline alt url (Just range)  -- ADD
   134→```
   135→
   136→**2.4 Create extractFacetsAndImages function** (new, after line 211)
   137→```haskell
   138→-- Extract facets from non-image inlines AND separate image inlines
   139→extractFacetsAndImages :: [Inline] -> (([Facet], Text), [(Text, Text)])
   140→extractFacetsAndImages inlines =

   147→    isImage _ = False
   148→```
   149→
   150→**2.5 Update paragraph/plain handlers** (lines 140-146)
   151→```haskell
   152→paragraph inlines =
   153→  let ((facets, plaintext), images) = extractFacetsAndImages inlines
   154→      textBlock = if Text.null plaintext then [] else [TextBlock RichText {plaintext, facets}]

   157→
   158→plain inlines =
   159→  let ((facets, plaintext), images) = extractFacetsAndImages inlines
   160→      textBlock = if Text.null plaintext then [] else [TextBlock RichText {plaintext, facets}]
   161→      imageBlocks = map mkUnresolvedImage images
   162→   in textBlock <> imageBlocks
   163→
   164→mkUnresolvedImage :: (Text, Text) -> BlockVariant
   165→mkUnresolvedImage (alt, url) = UnresolvedImageBlock $ UnresolvedImage
   166→  { imageSource = url
   167→  , imageAlt = if Text.null alt then Nothing else Just alt
   168→  }
   169→```
   170→
   171→**2.6 Handle ImageInline in extractFacet** (line 240)
   172→```haskell
   173→extractFacet :: Inline -> Converter -> Converter
   174→extractFacet = \case
   175→  ImageInline {} -> id  -- Images ignored in facet extraction, handled separately
   176→  Decorated f rge -> makeFacet f rge
   177→  Plain "\n" -> ...
   178→  Plain t -> ...
   179→```
   180→
   181→### Testing
   182→- Update pending test (LeafletSpec.hs:514) to verify UnresolvedImageBlock creation
   183→- Test single image, multiple images, with/without alt text
   184→- Test images in blockquotes, lists
   185→
   186→---
   187→
   188→## Phase 3: Image Resolution Module (High Risk)
   189→
   190→### New File
   191→- `src/Sensei/Bsky/Image.hs`
   192→
   193→### New Dependency
   194→Add to `sensei.cabal` build-depends:
   195→```
   196→, JuicyPixels  -- For image decoding and dimension extraction
   197→```
   198→
   199→### Module Structure
   200→
   201→```haskell
   202→module Sensei.Bsky.Image

   232→  Maybe Text ->      -- Alt text
   233→  m ResolvedImage
   234→```
   235→
   236→### Implementation Details
   237→
   238→1. **Detect source type**: HTTP/HTTPS URL vs file path
   239→2. **Fetch bytes**: Use http-client for URLs, readFile for local
   240→3. **Validate size**: Max 1MB (1,000,000 bytes)
   241→4. **Decode image**: Use JuicyPixels to extract dimensions
   242→5. **Detect MIME type**: Magic number detection (PNG/JPEG/GIF/WebP)
   243→6. **Return ResolvedImage**: All data ready for upload
   244→
   245→### Error Handling
   246→- File not found → ImageNotFound
   247→- Download failure → ImageDownloadFailed
   248→- Invalid format → ImageDecodeFailed
   249→- Too large → ImageTooLarge
   250→
   251→### Testing
   252→Create `test/Sensei/Bsky/ImageSpec.hs`:
   253→- MIME type detection (PNG, JPEG, GIF, WebP)
   254→- Size validation
   255→- Error cases (missing file, oversized, invalid format)
   256→- Integration with real test images

   366→
   367→## Implementation Sequence
   368→
   369→1. **Data structures** → Test with QuickCheck generators
   370→2. **Markdown parser** → Test with LeafletSpec
   371→3. **Image module** → Test with ImageSpec and test fixtures
   372→4. **Integration** → Test with mock uploadBlob
   373→5. **End-to-end** → Manual testing with real articles
   374→
   375→---
   376→
   377→## Critical Files
   378→
   379→1. `src/Sensei/Bsky/Leaflet.hs` - Data structures (AspectRatio, Image, UnresolvedImage)
   380→2. `src/Sensei/Bsky/Leaflet/Markdown.hs` - Parser (ImageInline, extractFacetsAndImages)
   381→3. `src/Sensei/Bsky/Image.hs` - NEW: Image resolution logic

   388→## Dependencies
   389→
   390→**New:**
   391→- `JuicyPixels` - Image decoding (BSD3 license)
   392→
   393→**Existing (leveraged):**

   400→
   401→## Risk Mitigation
   402→
   403→**High Risk: Image decoding**
   404→- Use well-established JuicyPixels library
   405→- Comprehensive error handling
   406→
   407→**High Risk: Network failures**
   408→- Clear error messages
   409→- Fail-fast approach (don't publish partial articles)
   410→
   411→**Medium Risk: Inline→Block mismatch**
   412→- UnresolvedImageBlock intermediate representation

## Approved Plan:
# Implementation Plan: Image Support in Markdown Articles

## Goal
Enable publishing and updating articles from markdown with embedded images, automatically uploading them as blobs to Bluesky PDS.

## Overview
1. Implement proper Image/ImageBlock/AspectRatio data structures per AT Protocol lexicon
2. Fix markdown parser to handle `![alt](url)` syntax
3. Resolve images (file/URL), compute aspect ratio, upload as blobs
4. Comprehensive unit and integration testing

---

## Phase 1: Data Structures (Low Risk)

### Files Modified
- `src/Sensei/Bsky/Leaflet.hs`
- `test/Sensei/Generators.hs`

### Changes

**1.1 Add AspectRatio type** (after line 439)
```haskell
data AspectRatio = AspectRatio
  { width :: Int
  , height :: Int
  }
  deriving stock (Eq, Show, Generic)
  deriving anyclass (ToJSON, FromJSON)
```

**1.2 Replace Image stub** (lines 440-444)
```haskell
data Image = Image
  { image :: Blob
  , aspectRatio :: AspectRatio
  , alt :: Maybe Text
  }
  deriving stock (Eq, Show, Generic)

instance ToJSON Image where
  toJSON Image {image = img, aspectRatio, alt} =
    object $
      [ "$type" .= BskyType @(Lexicon Image),
        "image" .= img,
        "aspectRatio" .= aspectRatio
      ] <> optionalField "alt" alt

instance FromJSON Image where
  parseJSON = withObject "Image" $ \v -> do
    _ <- v .: "$type"
    Image <$> v .: "image" <*> v .: "aspectRatio" <*> v .:? "alt"
```

**1.3 Add UnresolvedImage type** (for markdown parsing phase)
```haskell
-- Unresolved image from markdown, needs fetching/upload
data UnresolvedImage = UnresolvedImage
  { imageSource :: Text      -- URL or file path
  , imageAlt :: Maybe Text   -- Alt text
  }
  deriving stock (Eq, Show, Generic)
  deriving anyclass (ToJSON, FromJSON)
```

**1.4 Extend BlockVariant** (line 293)
```haskell
data BlockVariant
  = ...existing variants...
  | UnresolvedImageBlock UnresolvedImage  -- ADD
```

**1.5 Update ToJSON/FromJSON** (lines 311-331)
- Add `toJSON (ImageBlock img) = toJSON img` (line 318)
- Change line 326: `"pub.leaflet.blocks.image" -> ImageBlock <$> parseJSON (Object v)`
- Add UnresolvedImageBlock handling (internal only, not serialized to external JSON)

**1.6 Update Generators**
```haskell
instance Arbitrary AspectRatio where
  arbitrary = AspectRatio <$> choose (1, 4096) <*> choose (1, 4096)

instance Arbitrary Image where
  arbitrary = Image <$> arbitrary <*> arbitrary <*> arbitrary

instance Arbitrary UnresolvedImage where
  arbitrary = UnresolvedImage
    <$> elements ["https://example.com/image.png", "/path/to/image.png"]
    <*> arbitrary
```

### Testing
- JSON roundtrip tests for AspectRatio, Image
- QuickCheck property tests with generators

---

## Phase 2: Markdown Parser (Medium Risk)

### Files Modified
- `src/Sensei/Bsky/Leaflet/Markdown.hs`
- `test/Sensei/Bsky/LeafletSpec.hs`

### Key Challenge
CommonMark parses `![alt](url)` as **inline** element, but Leaflet requires **block-level** ImageBlock.

### Solution
1. Parse images as new `ImageInline` variant
2. In `paragraph`/`plain` handlers, separate images from text
3. Create UnresolvedImageBlock for each image

### Changes

**2.1 Extend Inline type** (line 102)
```haskell
data Inline
  = Plain Text
  | Decorated Feature (Maybe SourceRange)
  | ImageInline Text Text (Maybe SourceRange)  -- alt, url, range
  deriving (Eq, Show)
```

**2.2 Implement image function** (line 125)
```haskell
image url title inlines = inlines <> [ImageInline title url Nothing]
```

**2.3 Update Rangeable instance** (line 109)
```haskell
ranged range = \case
  Plain t -> Plain t
  Decorated f _ -> Decorated f (Just range)
  ImageInline alt url _ -> ImageInline alt url (Just range)  -- ADD
```

**2.4 Create extractFacetsAndImages function** (new, after line 211)
```haskell
-- Extract facets from non-image inlines AND separate image inlines
extractFacetsAndImages :: [Inline] -> (([Facet], Text), [(Text, Text)])
extractFacetsAndImages inlines =
  let nonImages = filter (not . isImage) inlines
      images = [(alt, url) | ImageInline alt url _ <- inlines]
      Converter {facets, plaintext} = foldl (flip extractFacet) initialConverter nonImages
   in ((facets, plaintext), images)
  where
    isImage (ImageInline {}) = True
    isImage _ = False
```

**2.5 Update paragraph/plain handlers** (lines 140-146)
```haskell
paragraph inlines =
  let ((facets, plaintext), images) = extractFacetsAndImages inlines
      textBlock = if Text.null plaintext then [] else [TextBlock RichText {plaintext, facets}]
      imageBlocks = map mkUnresolvedImage images
   in textBlock <> imageBlocks

plain inlines =
  let ((facets, plaintext), images) = extractFacetsAndImages inlines
      textBlock = if Text.null plaintext then [] else [TextBlock RichText {plaintext, facets}]
      imageBlocks = map mkUnresolvedImage images
   in textBlock <> imageBlocks

mkUnresolvedImage :: (Text, Text) -> BlockVariant
mkUnresolvedImage (alt, url) = UnresolvedImageBlock $ UnresolvedImage
  { imageSource = url
  , imageAlt = if Text.null alt then Nothing else Just alt
  }
```

**2.6 Handle ImageInline in extractFacet** (line 240)
```haskell
extractFacet :: Inline -> Converter -> Converter
extractFacet = \case
  ImageInline {} -> id  -- Images ignored in facet extraction, handled separately
  Decorated f rge -> makeFacet f rge
  Plain "\n" -> ...
  Plain t -> ...
```

### Testing
- Update pending test (LeafletSpec.hs:514) to verify UnresolvedImageBlock creation
- Test single image, multiple images, with/without alt text
- Test images in blockquotes, lists

---

## Phase 3: Image Resolution Module (High Risk)

### New File
- `src/Sensei/Bsky/Image.hs`

### New Dependency
Add to `sensei.cabal` build-depends:
```
, JuicyPixels  -- For image decoding and dimension extraction
```

### Module Structure

```haskell
module Sensei.Bsky.Image
  ( resolveImage
  , ImageResolutionError(..)
  , ResolvedImage(..)
  ) where

-- Errors during image resolution
data ImageResolutionError
  = ImageNotFound Text
  | ImageTooLarge Text Int       -- path, actual size
  | ImageDownloadFailed Text Text -- url, reason
  | ImageDecodeFailed Text Text   -- source, reason
  deriving (Eq, Show, Generic)

instance Exception ImageResolutionError

-- Fully resolved image ready for upload
data ResolvedImage = ResolvedImage
  { imageBytes :: BS.ByteString
  , imageWidth :: Int
  , imageHeight :: Int
  , mimeType :: Text
  , altText :: Maybe Text
  }

-- Resolve image source (file/URL) to bytes and metadata
resolveImage ::
  (MonadIO m, MonadCatch m) =>
  Maybe FilePath ->  -- Base directory for relative paths
  Text ->            -- Image source (file path or URL)
  Maybe Text ->      -- Alt text
  m ResolvedImage
```

### Implementation Details

1. **Detect source type**: HTTP/HTTPS URL vs file path
2. **Fetch bytes**: Use http-client for URLs, readFile for local
3. **Validate size**: Max 1MB (1,000,000 bytes)
4. **Decode image**: Use JuicyPixels to extract dimensions
5. **Detect MIME type**: Magic number detection (PNG/JPEG/GIF/WebP)
6. **Return ResolvedImage**: All data ready for upload

### Error Handling
- File not found → ImageNotFound
- Download failure → ImageDownloadFailed
- Invalid format → ImageDecodeFailed
- Too large → ImageTooLarge

### Testing
Create `test/Sensei/Bsky/ImageSpec.hs`:
- MIME type detection (PNG, JPEG, GIF, WebP)
- Size validation
- Error cases (missing file, oversized, invalid format)
- Integration with real test images

---

## Phase 4: Integration (High Risk)

### Files Modified
- `src/Sensei/Bsky.hs`

### New Functions

**4.1 resolveDocumentImages**
```haskell
-- Resolve all UnresolvedImageBlocks in a LinearDocument
resolveDocumentImages ::
  (MonadIO m, MonadCatch m) =>
  BskyClientConfig ->
  Maybe FilePath ->     -- Base directory for relative paths
  LinearDocument ->
  m (Either String LinearDocument)
```

**4.2 resolveAndUploadImage**
```haskell
-- Resolve image source and upload to Bluesky
resolveAndUploadImage ::
  (MonadIO m, MonadCatch m) =>
  BskyClientConfig ->
  Maybe FilePath ->
  Text ->          -- Image source
  Maybe Text ->    -- Alt text
  m Image
```

### Integration Flow

```
markdown → mkMarkdownDocument → LinearDocument (with UnresolvedImageBlocks)
        → resolveDocumentImages → LinearDocument (with ImageBlocks)
        → create Document → publish
```

**4.3 Update publishArticle** (line 394)
```haskell
publishArticle doPublish backend session articleOp = do
  linearDocResult <- liftIO $ mkMarkdownDocument body
  case linearDocResult of
    Left err -> pure $ Left $ "Failed to parse markdown: " <> err
    Right linearDoc -> do
      -- NEW: Resolve images
      let clientConfig = BskyClientConfig {backend, bskySession = Just session}
      resolvedDocResult <- resolveDocumentImages clientConfig baseDir linearDoc

      case resolvedDocResult of
        Left err -> pure $ Left $ "Failed to resolve images: " <> err
        Right resolvedDoc -> do
          -- Continue with existing flow...
```

**4.4 Update updateArticle** (similar changes at line 459)

### Base Directory Context

**Resolution**: Use `_articleDir` field from Article as the base directory for resolving relative file paths. This represents the current working directory when the article command was invoked.

**Implementation**: Pass `_articleDir` as the `baseDir` parameter to `resolveDocumentImages`.

### Testing
- End-to-end test with markdown containing images
- Mock uploadBlob for testing without network
- Error propagation tests

---

## Phase 5: Testing & Polish

### Test Coverage

**Unit Tests**
- [ ] AspectRatio/Image JSON roundtrip
- [ ] UnresolvedImage creation from markdown
- [ ] Image MIME type detection
- [ ] Size validation (1MB limit)
- [ ] Dimension extraction

**Parser Tests**
- [ ] Single image in markdown
- [ ] Multiple images in paragraph
- [ ] Image with/without alt text
- [ ] Images in blockquotes and lists
- [ ] Mixed text and images

**Integration Tests**
- [ ] Full flow: markdown → parse → resolve → upload → publish
- [ ] Error handling for each failure mode
- [ ] Relative and absolute path resolution

**Error Cases**
- [ ] Missing file
- [ ] Oversized image (>1MB)
- [ ] Invalid image format
- [ ] Network failure for remote URLs
- [ ] Upload API failure

### Documentation
- Update CLAUDE.md with image support info
- Add examples of markdown with images

---

## Implementation Sequence

1. **Data structures** → Test with QuickCheck generators
2. **Markdown parser** → Test with LeafletSpec
3. **Image module** → Test with ImageSpec and test fixtures
4. **Integration** → Test with mock uploadBlob
5. **End-to-end** → Manual testing with real articles

---

## Critical Files

1. `src/Sensei/Bsky/Leaflet.hs` - Data structures (AspectRatio, Image, UnresolvedImage)
2. `src/Sensei/Bsky/Leaflet/Markdown.hs` - Parser (ImageInline, extractFacetsAndImages)
3. `src/Sensei/Bsky/Image.hs` - NEW: Image resolution logic
4. `src/Sensei/Bsky.hs` - Integration (resolveDocumentImages, publishArticle/updateArticle)
5. `test/Sensei/Bsky/LeafletSpec.hs` - Parser tests
6. `test/Sensei/Bsky/ImageSpec.hs` - NEW: Image resolution tests

---

## Dependencies

**New:**
- `JuicyPixels` - Image decoding (BSD3 license)

**Existing (leveraged):**
- `http-client` - Already in deps, for remote image fetching
- `http-client-tls` - Already in deps
- `aeson` - JSON serialization
- `safe-exceptions` - Error handling

---

## Risk Mitigation

**High Risk: Image decoding**
- Use well-established JuicyPixels library
- Comprehensive error handling

**High Risk: Network failures**
- Clear error messages
- Fail-fast approach (don't publish partial articles)

**Medium Risk: Inline→Block mismatch**
- UnresolvedImageBlock intermediate representation
- Clean separation of parsing and resolution phases
