* feat(hub,shared): scratchlist v2.2 hub attachment storage foundation (#921) Hub stores scratchlist attachment bytes on filesystem; SQLite holds AttachmentMetadata[] JSON via session_scratchlist.attachments (v11→v12). Upstream ladder: v10→v11 text-only scratchlist table (#896), v11→v12 attachments column. Configurable limits via HAPI_SCRATCHLIST_* env vars. Upload, serve, and limits REST routes; delete entry cleans hub files. Web promote/rehydrate still TODO. Soup renumber branch follows. Co-authored-by: Cursor <cursoragent@cursor.com> * feat(web): scratchlist v2.2 attachment UX (#921) Route scratchlist-mode composer submits with attachments to hub storage, show image thumbnails in the drawer, and rehydrate attachments on promote to composer or queue (hub fetch → CLI upload for send). Co-authored-by: Cursor <cursoragent@cursor.com> * fix(web): scratchlist attach submit, float thumbs, copy tooltip (#921) Hub upload adapter now sets path on ready attachments so the composer send button unlocks in scratchlist mode; routing label matches attachments too. Entry thumbnails float left with text wrap; copy tooltip clarifies text-only. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(hub): adapt scratchlist update tests to patch API (#921) update() now takes { text?, attachments? }; v12 CRUD tests still passed a string. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(hub,web): harden scratchlist attachment ownership and orphan cleanup Resolve claimed hub paths against the current session before persist, count on-disk session bytes for upload caps, delete blobs dropped on entry update, and DELETE pending uploads when composer remove runs. Co-authored-by: Cursor <cursoragent@cursor.com> * chore: drop accidental .cursor files from attachment PR Co-authored-by: Cursor <cursoragent@cursor.com> * fix(web): exit scratchlist mode before rehydrate; delete raced uploads Promote-to-composer flushes mode exit so attachments use the chat adapter. Cancel-during-upload deletes the hub blob once upload returns. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(hub,web): exact UUID delete match; stage hub paths on chat send Reject partial attachment ids on disk delete, and restage scratchlist hub attachments through uploadFile when sending after leaving scratchlist mode. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(hub): skip text-only PUT resolve; cleanup session attachment dirs Text-only edits keep existing attachment metadata after session-id transfer. Require full UUID on resolve. Delete scratchlist attachment files when a session is deleted. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(hub,web): scratchlist attach route, PUT bytes, orphan deletes Park only hub-resident attachments; subtract removed blobs from the PUT session cap; delete attachment files only when no other entry still references them. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(hub): canonicalize scratchlist attachment filenames Resolve stores the on-disk sanitized name (not claimed.filename) and hardens Content-Disposition against CR/LF/quote injection. Co-authored-by: Cursor <cursoragent@cursor.com> * test(hub): cover toxic filename canonicalize on resolve Co-authored-by: Cursor <cursoragent@cursor.com> * fix(hub,web): serialize scratchlist uploads; drop hub blobs after chat stage Per-session upload lock keeps disk byte caps honest under concurrency. After a successful toggle-off chat send, delete the staged hub copies so they no longer count against the session attachment budget. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(shared,web): allow clearing scratchlist attachments; cleanup staged uploads PUT may send attachments:[] without a text change. Staging to chat rolls back partial normal-upload copies on failure. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(hub): re-key scratchlist attachment files on session merge Move hub blobs when scratchlist rows transfer between session ids so quota and path ownership stay correct. Reject PUT that would leave an empty textless entry after clearing attachments. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(web): reuse restored scratchlist hub attachments without re-upload Composer draft remount was re-uploading blobs that already had a hapi-hub:scratchlist path, orphaning the originals against session quota.

What it does
- Telegram bot for notifications and the Mini App entrypoint.
- HTTP API for sessions, messages, permissions, machines, and files.
- Server-Sent Events stream for live updates in the web app.
- Socket.IO channel for CLI connections.
- Serves the web app from
web/distor embedded assets in the single binary. - Persists state in SQLite.
Configuration

Running
Binary (single executable):
export TELEGRAM_BOT_TOKEN="..."
export CLI_API_TOKEN="shared-secret"
export HAPI_PUBLIC_URL="https://your-domain.example"
hapi hub
hapi server remains supported as an alias.
If you only need web + CLI, you can omit TELEGRAM_BOT_TOKEN.
To enable Telegram, set TELEGRAM_BOT_TOKEN and HAPI_PUBLIC_URL, start the hub, open /app
in the bot chat, and bind the Mini App with CLI_API_TOKEN:<namespace> when prompted.
From source:
bun install
bun run dev:hub

- Permission approval/denial.
- RPC method routing via Socket.IO.
- Event publishing to SSE and Telegram.

Security model
Access is controlled by:
- Telegram initData verification plus bound Telegram users (bound via
CLI_API_TOKEN:<namespace>). CLI_API_TOKENbase secret for CLI and browser access (namespace is appended by clients).
Transport security depends on HTTPS in front of the hub.
Build for deployment
From the repo root:
bun run build:hub
bun run build:web
The hub build output is hub/dist/index.js, and the web assets are in web/dist.
Networking notes
- Telegram Mini Apps require HTTPS and a public URL. If the hub has no public IP, use Cloudflare Tunnel or Tailscale and set
HAPI_PUBLIC_URLto the HTTPS endpoint. - If the web app is hosted on a different origin, set
CORS_ORIGINS(orHAPI_PUBLIC_URL) to include that static host origin.
Standalone web hosting
The web UI can be hosted separately from the hub (for example on GitHub Pages or Cloudflare Pages):
- Build and deploy
web/distfrom the repo root. - Set
CORS_ORIGINS(orHAPI_PUBLIC_URL) to the static host origin. - Open the static site, click the Hub button on the login screen, and enter the hapi hub origin.
Leaving the hub override empty preserves the default same-origin behavior when the hub serves the web assets directly.
