Render the content pane as tabs of nested split trees, each session leaf a live attach mounted through the multi-mount pool: - #30 arbitrarily-nested H/V splits with mouse-resizable dividers; per-pane ⏻/▥/▤/✕ tools; closing a pane collapses its parent split. - #31 tabs, each holding its own tree; add / switch / close. - #32 drag-to-dock: drag a pane title or a sidebar session onto a pane for a 5-zone dock (edges split, centre swaps/replaces); a sidebar drag moves an already-open session. - #33 focused pane at full strength, others dim; sidebar shows focused (loud) vs open-elsewhere (quiet) with a stable per-session colour mapping rows to panes. Opening a session fills the focused pane (single-pane parity by default); multi-pane is opt-in via split / drag / tabs. Panes auto-close when their session ends (guarded against eviction and intentional close). The steady "connected" label is hidden as noise. Closes #30, #31, #32, #33. Part of epic #37.

maestro-web
Browser UI for Maestro. Connects to the registry HTTP/WS API for the catalog and to individual daemons (via direct WebSocket) for terminal I/O.
Framework choice: vanilla TypeScript
No frontend framework. The UI is small enough that the cost of pulling in Preact / Solid / Leptos doesn't pay back. xterm.js does all the heavy rendering; everything else is a session tree and a spawn form, both trivial in plain DOM.
This decision is non-architectural — swap in a framework later without touching the registry or daemon if needed.
Layout
src/
main.ts # entry point, hash-route dispatch
api.ts # registry HTTP API client
events.ts # `/api/events` WebSocket subscriber
catalog.ts # session tree view (groups by metadata.label)
attach.ts # xterm.js + daemon WS attach view
spawn.ts # spawn-session modal
theme.ts # dark/light theme toggle + persistence
types.ts # mirror of `maestro-protocol` JSON shapes
styles.css # design-system tokens + component styles
mock.ts # DEV-only review fixture (see Design)
Design
The visual system (OKLCH token palette, monospace-first typography, dark+light
theming, motion, components) is documented in ../DESIGN.md;
the tokens live in the :root block of src/styles.css. Strategic intent
(register, brand, principles) is in ../PRODUCT.md. Theme
follows the OS by default and can be pinned via the header toggle (persisted in
localStorage).
mock.ts is a DEV-only fixture (stripped from production builds): visit the dev
server with ?mock to seed a representative catalog without a running registry,
?mock&spawn to open the spawn modal, and ?theme=light|dark to pin a theme.
Routing is hash-based:
#/→ catalog#/attach/<session-id>→ terminal
This keeps the registry's static handler dumb (no SPA fallback needed).
Concurrent attaches: open the same #/attach/<id> URL in another tab.
Dev
pnpm install
pnpm dev # http://localhost:5173, proxies /api → http://127.0.0.1:8080
pnpm build # → dist/, embedded into the registry binary at cargo build time
The Vite dev server proxies /api and the events WebSocket to a
maestro-registry. Default is http://127.0.0.1:8080; point it elsewhere by
exporting MAESTRO_REGISTRY before pnpm dev:
MAESTRO_REGISTRY=https://maestro-registry.example.com pnpm dev
# Daemon-facing URL also works — `wss://...` is rewritten to `https://...`
# and a trailing `/daemon` is stripped.
MAESTRO_REGISTRY=wss://maestro-registry.example.com/daemon pnpm dev
Direct daemon WS connections (for attach) bypass the proxy and use the URL
returned by GET /api/sessions/:id/connect-info.
Production
pnpm build writes the bundle to web/dist/. The Rust registry crate
embeds that directory via rust-embed at compile time and serves it from
/. See crates/maestro-registry/src/web_assets.rs.
