The existing-branch picker could never succeed in either client: both treated the main checkout's HEAD as available, and since that is usually `main` it became the default pick — git then refuses the second checkout. A TUI test had baked the bug in by asserting the selection lands on the `is_head` entry. Both pickers now treat "checked out anywhere" as held. Worktree paths were still not injective. Flattening `/` and `.` to `-` made `feat/x`, `feat.x` and `feat-x` share one directory, and the override root keyed on the repo basename alone, so `~/a/maestro` and `~/b/maestro` collided. A branch name is already a valid relative path — git stores it as refs/heads/feat/example — so it is used verbatim and nests under `worktrees/feat/`; the override root gains a digest of the full repo path. Git forbids holding both `feat` and `feat/x`, so the nesting cannot collide for valid refs. Also: - Recovered sessions dropped their worktree association, so after a restart a kill cleaned up nothing and the leftover directory blocked that branch forever. It is persisted on Session now. - The nesting guard compared git's resolved paths against an unresolved one, so it silently passed on any symlinked repo path — and that guard is what stands between a kill and an inner tree's uncommitted work. - Draft loads ran on the TUI event loop: /api/projects on a cold cache walks all of $HOME, freezing keys, frames and attached panes for up to the request timeout. They are detached tasks posting to a channel now. - Fast-forward in the web client created the session and never mounted it, so `N` looked like a dead key while the TUI attached. - The fast-forward fallback seed forced the worktree toggle off, against both a normal draft and the TUI. - The projects background refresh honoured the TTL, so two of every three ticks were no-ops and requests paid for the rescan instead.
maestro-web
Browser UI for Maestro. Talks to a single local daemon over its /api/*
HTTP/WS surface — session catalog, spawn/kill, and 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 daemon if needed.
Layout
src/
main.ts # entry point, hash-route dispatch
api.ts # daemon HTTP API client
events.ts # `/api/events` WebSocket subscriber
catalog.ts # session tree view (groups by working directory)
attach.ts # xterm.js + attach WS view
multiview.ts # tabs + split panes; draft panes host the spawn form
spawnForm.ts # shared spawn form (preset tiles, project picker, worktree)
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 daemon,
?mock&spawn to open a draft pane, and ?theme=light|dark to pin a theme.
Routing is hash-based:
#/→ catalog#/attach/<session-id>→ terminal
This keeps the 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://127.0.0.1:7070
pnpm build # → dist/, embedded into the maestro-web binary at cargo build time
The Vite dev server proxies /api and the WebSockets to a local daemon.
Default is http://127.0.0.1:7070; point it elsewhere by exporting
MAESTRO_DAEMON_URL before pnpm dev:
MAESTRO_DAEMON_URL=http://laptop.lan:7070 pnpm dev
Production
pnpm build writes the bundle to web/dist/. The maestro-web crate embeds
that directory at compile time and serves it from /, reverse-proxying /api/*
to the daemon. See crates/maestro-web/src/static_bundle.rs.
