When a post is deleted from the web backend (Micropub action=delete), call each registered syndicator's delete() method so the post is also removed from the Fediverse (AP Delete/Tombstone) and Bluesky (com.atproto.repo.deleteRecord). - patch-bluesky-syndicator-delete: adds Bluesky#deletePost(bskyUrl) to lib/bluesky.js and BlueskySyndicator#delete(url, syndication) to index.js; the bsky.app URL is resolved from the syndication array that postData.delete() preserves in _deletedProperties - patch-micropub-delete-propagation: patches action.js case "delete" to iterate publication.syndicationTargets after postContent.delete() and fire syndicator.delete() fire-and-forget for any syndicator that exposes the method (errors logged, never break the 200 response) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

/**
|
|
* Patch: propagate Micropub deletes to registered syndicators.
|
|
*
|
|
* Bug:
|
|
* action.js case "delete" only calls postData.delete() + postContent.delete().
|
|
* It never notifies syndicators, so deleting a post from the web backend
|
|
* leaves orphaned copies on ActivityPub (Fediverse) and Bluesky.
|
|
*
|
|
* Fix:
|
|
* After postContent.delete() returns, iterate publication.syndicationTargets
|
|
* and call syndicator.delete(url, syndication) on any syndicator that exposes
|
|
* the method. The syndication URLs are read from data._deletedProperties
|
|
* (preserved by postData.delete() before stripping the properties).
|
|
*
|
|
* Errors from individual syndicators are caught and logged — a failed remote
|
|
* delete must never break the 200 response for the local delete.
