Publishing:
- Only send alt text for images (isImage guards on LinkedIn, X, Discord, Mastodon); never inject altText into video/document payloads.
- X sets alt via a best-effort media/metadata call so a metadata failure no longer blocks the tweet.
Validation:
- Validate media alt_text with a closure on media.*.meta so width/height/duration/slide_* survive a post update (Laravel's excludeUnvalidatedArrayKeys was stripping them).
- Add ALT_TEXT_MAX_LENGTH constant, a proper string-type error, and a localized attribute name.
Media attach (REST + MCP):
- Support per-image alt on attach-media-from-url via structured urls: [{url, alt?}] and on the MCP upload tool via an optional alt; alt is stored only for images.
- Carry submitted meta onto hosted external-URL media so alt is no longer dropped.
Composer:
- Alt-text dialog disables Save and reddens the counter over the limit, counting code points of the trimmed value to match the backend.
- Autosave shows 'Saved' only on a successful response; the lightbox alt overlay renders for images only.
Adds unit, feature, MCP, and browser tests covering every path above.
Adds POST /api/posts/{post}/media for direct file (multipart) upload
and renames the existing URL-based flow to /api/posts/{post}/media/from-url
so the path matches HTTP semantics (POST <resource>/media expects a file
body, not JSON URLs).
The multipart action validates type against the post's enabled platforms
(image rejected on TikTok-only posts), enforces per-type size caps, and
reuses Workspace::addMedia + Post::appendMedia. URL-based attaching is
unchanged behaviorally — only the route name and controller method are
renamed for symmetry. The MCP AttachMediaFromUrlTool was already named
correctly and needs no changes; binary upload via MCP is a host-protocol
limitation that no MCP server (including Postiz) supports.
