Summary

Bluesky supports thread chains (reply to own posts) and quote posts. For long articles, auto-splitting into a thread is valuable.

Thread Support

Reply chain via root + parent references:

{
  "reply": {
    "root": {"uri": "at://...", "cid": "..."},
    "parent": {"uri": "at://...", "cid": "..."}
  }
}

Auto-Thread Logic

If message exceeds 300 graphemes, split at sentence boundaries
First post is the root
Subsequent posts reply to the previous one
Last post includes the article URL

Quote Posts

Embed type app.bsky.embed.record:

{
  "embed": {
    "$type": "app.bsky.embed.record",
    "record": {"uri": "at://...", "cid": "..."}
  }
}

External Link Cards

Already supported via app.bsky.embed.external but our plugin doesn't use it. Should generate link cards with title/description/thumbnail.

Acceptance Criteria

Auto-thread when message exceeds 300 graphemes
Smart splitting at sentence boundaries
External link card embed for article URLs
Quote post support via params

Implemented in commit 5fee5d7. Bluesky auto-threads: splitIntoThread() splits at sentence boundaries (. ! ? followed by space) with 30% minimum segment threshold before falling back to word breaks. Thread posts use reply.root + reply.parent references. External link card (app.bsky.embed.external) attached to the last post in thread with article title/description. Single posts under 300 chars use the simpler createPost() path. Dispatcher now passes article_title to all service plugins via params.

Testing Checklist

Migrated from #175

Test Steps

Auto-Thread

Messages under 300 chars post as single post (no thread)
Messages over 300 chars split into thread at sentence boundaries
Thread posts linked via reply.root + reply.parent references
Sentence splitting prefers ". " / "! " / "? " breaks
Falls back to word boundary when no sentence break in first 30%
Article URL attached to last post in thread
Root post URI stored as platform_post_id
Response includes thread_count

Link Card Embeds

Single posts include app.bsky.embed.external with article URL
Link card has article title and description
Thread posts: link card on last post only

Existing Behavior

Session caching still works (sha256 cache key)
Delete still works (rkey extraction from AT URI)

Namespace Fix

bluesky.xml namespace is Joomla\Plugin\MokoSuiteCross\Bluesky (not ${CLASS_NAME})
