+Title: Gateway Web Chat: add image/file upload (attach, drag-drop, paste)
+
+Summary
+- Adds attachment support in Gateway web Chat: attach button, drag & drop, and paste-from-clipboard for images.
+- Backend: multipart upload endpoint that stores files under the instance media dir and returns MEDIA:/ paths; message API extended to accept media[].
+- Frontend: composer queue with file chips, upload progress; message renderer for thumbnails and file tiles.
+
+Motivation
+Users of the web console need to share screenshots/logs directly in the browser. Today there is no upload mechanism.
+
+Implementation (draft)
+- Backend
+  - POST /api/media/upload (multipart, repeatable file field). Saves to ~/.clawdbot/media/inbound/<uuid>.<ext>, returns { files: [{ path: 'MEDIA:/...', mime, name, size }] }.
+  - Extend message creation to accept media[] in addition to text.
+- Frontend
+  - Attach button + hidden input[type=file] multiple.
+  - Drag & drop overlay and handlers on composer.
+  - Paste handler captures image blobs from clipboard.
+  - Attachment queue with progress; after upload, send text + media paths.
+  - Message renderer displays thumbnails for images and links for other files.
+
+Config & Limits
+- Defaults: 25MB per file; up to 5 files per message. Configurable via gateway config.
+
+Security
+- Sanitized filenames; type/size validation; stored under instance media path; served via existing media route (auth/signed URLs as applicable).
+
+Acceptance Criteria
+- Drag/paste/attach works; messages show thumbnails or file tiles; assistant receives MEDIA:/path.
+
+Notes
+This PR ships as a draft to align on API shape and UI placement. Happy to adjust to the codebase conventions and routing.

+# Gateway Web Chat: Image/File Upload
+
+Status: draft
+Owner: @assistant
+Scope: Gateway web console (Chat)
+
+## Problem
+The Gateway web Chat has no way to send images/files. Users often need to share screenshots/logs during troubleshooting.
+
+## Goals
+- Allow users to attach files via: attach button, drag & drop, paste-from-clipboard (images).
+- Show selected files as removable chips with upload progress.
+- On send, upload files to server and insert a message with media references so assistants receive MEDIA:/path.
+- Support multiple files per message.
+- Reasonable defaults for limits (20–50MB per item) and allow config override.
+
+## Non-goals
+- Inline buttons/interactive UI in messages (not supported on webchat).
+- Server-side virus scanning.
+
+## UX
+- Add "Attach" icon next to the composer.
+- Dragging files over the composer shows a drop overlay.
+- Pasting an image inserts it as a pending attachment.
+- Each selected file shows: name/size, thumbnail for images, remove (×), progress bar while uploading.
+- Pressing Enter (without Shift) sends text + queued attachments.
+
+## API
+- POST /api/media/upload (multipart/form-data)
+  - fields: file (repeatable), caption (optional, per-file or per-message caption TBD)
+  - returns 200 JSON: { files: [ { path: "MEDIA:/path", mime: "image/png", name: "...", size: 12345, width, height } ] }
+  - saves files under gateway media path (e.g., ~/.clawdbot/media/inbound/<uuid>.<ext>)
+- POST /api/sessions/:sessionId/messages
+  - body: { text?: string, media?: [ { path: "MEDIA:/...", caption?: string } ] }
+  - server stores transcript and delivers to assistant runtime.
+
+Notes:
+- If a single endpoint already exists to send messages, extend it to accept media[]. Otherwise, use two-phase (upload -> send).
+- Respect existing auth/session; CSRF as per current gateway conventions.
+
+## Backend
+- Add multipart handling (e.g., busboy/multer/fastify-multipart depending on stack).
+- Validate content type and size; enforce configurable limits.
+- Compute a safe filename; store to media dir; produce absolute server path and MEDIA:/ prefix for assistant.
+- For images: attempt to read dimensions (optional) to improve thumbnails.
+- Return JSON list of stored files.
+- Extend message creation to accept media[]. Persist media metadata alongside messages for rendering.
+
+## Frontend
+- Composer component changes:
+  - Add hidden <input type="file" multiple> bound to Attach button.
+  - Drag & drop overlay and handlers (dragenter/dragover/drop) on composer area.
+  - Clipboard paste handler: capture image blobs and add to attachment queue.
+  - Attachment queue state: { id, file|blob, name, size, previewURL, status: queued|uploading|done|error, serverPath? }[]
+  - On send: for any queued files not uploaded, call /api/media/upload, show per-file progress. Then call send-message with text + media paths.
+  - After success: clear input and queue.
+- Message renderer: if message.media exists, render thumbnails for images and file tiles for others; clicking downloads the file.
+
+## Config
+- gateway.webchat.uploads.maxItemMB (default 25)
+- gateway.webchat.uploads.maxFilesPerMessage (default 5)
+- gateway.webchat.uploads.accept (default images+generic: "image/*,application/pdf,.zip,.txt")
+
+## Security
+- Store under per-instance media directory; do not serve arbitrary FS paths.
+- Serve media via controlled route with auth (or signed URLs) to avoid leaking private files.
+- Sanitize filenames; block executables by default if desired.
+
+## Acceptance Criteria
+- Drag a screenshot into composer -> shows chip -> send -> message appears with thumbnail; assistant receives MEDIA:/path.
+- Click attach to select multiple files -> progress -> all appear in transcript.
+- Paste an image from clipboard -> becomes attachment and can be sent.
+- Oversize file is rejected with a clear error.
+
+## Test Plan
+- Unit: multipart handler, limit enforcement, message payload schema.
+- E2E: browser test for drag/drop, paste, attach; verify message persistence and media retrieval.
+
+## Open Questions
+- Do we want per-file captions? For MVP we can skip.
+- Serving media: public path vs. signed URL behind auth — follow current Gateway approach.
+
+## Task Breakdown
+- [ ] Backend: media upload endpoint + storage
+- [ ] Backend: extend message API to accept media[]
+- [ ] Frontend: composer (attach/drag/paste) + queue + progress
+- [ ] Frontend: message renderer for media
+- [ ] Config + docs
+- [ ] Tests
