The two prior MUL-3254 fixes preserved draft/description state across a modal close, but Desktop still could not RENDER the reopened image: in CloudFront signed-URL mode every URL the renderer holds after reopen is unloadable. The persisted record strips the expired signed download_url, the raw CDN url is unsigned (403 on a signed distribution), and the durable /api/attachments/<id>/download endpoint needs credentials that a cross-site file:// <img> fetch cannot carry (web works via the same-site session cookie, which is why the bug was desktop-only). Two changes close the last mile: - /api/config now reports cdn_signed when CloudFront signing is enabled, and pickInlineMediaURL stops picking the raw (unsigned) CDN url in that mode — it is a guaranteed 403. - The Attachment renderer upgrades an auth-gated media URL to a freshly signed one via authenticated GET /api/attachments/<id> (the same re-sign the click-time download path already does), but only on clients without a same-origin /api proxy (api.getBaseUrl() non-empty: Desktop, mobile webview). Cached via TanStack Query with a 20-minute staleTime, inside the server's 30-minute signed-URL TTL. Old servers omit cdn_signed; the schema defaults it to false so behavior is unchanged there. Non-CloudFront deployments return the API path again from the metadata fetch and the renderer keeps the original URL. Co-authored-by: J <j@multica.ai> Co-authored-by: multica-agent <github@multica.ai>
