+A terminal-session orchestrator for one machine. One daemon per host owns every
+interactive shell or agent (Claude Code, opencode, plain bash) running on it;

-## Where the spec lives
+## Architecture

-`docs/superpowers/specs/2026-05-24-maestro-design.md` is the source of truth for architecture, wire protocol, session model, auth, repo layout, and scope boundary. **Read it before writing any code in this repo.**

+maestro-web                         serves the SPA, reverse-proxies /api/* to the daemon
+```
+
+**No authentication layer, no registry, no peer-to-peer.** Whoever can reach the
+daemon's bind address can drive every session on the host — same trust model as
+tmux itself. The operator picks the perimeter: `127.0.0.1` for local-only, a
+WireGuard/LAN address to share with their own devices, never a public IP.
+
+Every config field has a default, so `~/.config/maestro/config.toml` is
+optional.

 ## Where the work is

-Linear project **Maestro** under team **Naps62**. Issues `NAP-211..218` cover the prototype; each has `blockedBy` set so the dependency chain is explicit. **`NAP-211` is the only unblocked starting point.**
+Linear project **Maestro** under team **Naps62**.

-`.claude/linear.json` wires `/yolo` and `/work` to this project — they pick from "available now" (status backlog/pending, not blocked).

+## Repo layout

-Cargo workspace, populated incrementally starting with NAP-211:
+Cargo workspace. NAP-245 unified the per-binary crates behind a single
+`crates/maestro/` umbrella that ships the `maestro` binary with feature gates
+(`cli` / `daemon` / `tui`, default = all three).

 See `docs/INSTALL.md` for end-user install instructions.

+`docs/WORKTREES.md` is the contract for session worktrees — placement,
+collisions, what blocks a kill, what `--force` retains, and what reclaim
+touches. Read it before changing anything that creates or removes one.
+
+`docs/SIDEBAR.md` is the contract for session cards in the web and TUI
+sidebars — line layout, activity colours, duration format, state precedence.
+Read it before changing sidebar rendering.
+
+`nix run .#dev` (or `just dev`) brings up the whole local stack under
+process-compose: a debug daemon on 127.0.0.1:7071, then Vite on :5173 once the
+daemon answers `/api/info`. The SPA proxies `/api/*` back to the daemon, so only
+the UI is exposed on the network. The dev port is deliberately not the daemon's
+own default 7070 (`devDaemonPort` in `flake.nix`), so the stack never fights a
+real daemon on the same host.
+
 ## Conventions

 - **TDD by default.** Failing test first, then minimal impl. Commit test + impl together.
 - **Frequent commits.** One logical unit per commit; don't pile work up.
 - **Conventional commits with `maestro` scope.** Example: `feat(maestro): add Hello message round-trip test`.
- **`cargo fmt` + `cargo clippy --all-targets -- -D warnings`** before every commit. (Add to CI as part of NAP-211.)
+- **`cargo fmt` + `cargo clippy --all-targets -- -D warnings`** before every commit.
 - **Integration tests use real `tmux` and `git`.** Don't mock them. Isolate via temp `$HOME` and `TMUX_TMPDIR`.
-
-## Network assumption
-
-Maestro is network-agnostic. The operator chooses bind addresses; the perimeter is whatever VPN (Wireguard, etc.) or private LAN they've set up. Maestro does not terminate TLS itself or police the network. See spec §Auth.
-
-## Status
-
-Empty repo. Spec approved and committed. **NAP-211 is the natural start.**

+# Design
+
+Visual system for the Maestro web UI. Source of truth is
+`web/src/styles.css` (`:root` token block); this document mirrors it. Register:
+**product** — design serves the task. See [PRODUCT.md](PRODUCT.md) for strategy.
+
+## Theme
+
+Dark is the default (terminal context); light is a full peer. Everything is
+driven by CSS custom-property tokens, so a theme is a token swap, never a
+restyle. Resolution order:
+
+1. `:root[data-theme="light"|"dark"]` — explicit user pin (persisted in
+   `localStorage` as `maestro-theme`), set by the header toggle.
+2. `@media (prefers-color-scheme: light)` — followed when the user hasn't
+   pinned a theme.
+3. Otherwise the `:root` defaults (dark).
+
+The xterm terminal stays dark in both themes by convention; `--term-bg` is dark
+in light mode too.
+
+## Color (OKLCH)
+
+Strategy: **Restrained** (product floor) with one committed signal hue —
+**green = "alive"**, carrying running status, primary action, focus, and
+selection. Neutrals are a cool slate (hue ~256). Green is the signal, never a
+costume: text stays neutral high-contrast, surfaces stay slate, so the result
+reads terminal-native without CRT novelty.
+
+| Role | Dark | Light |
+|---|---|---|
+| `--bg` | `oklch(0.178 0.012 256)` | `oklch(0.985 0.003 256)` |
+| `--surface` | `oklch(0.214 0.014 256)` | `oklch(1 0 0)` |
+| `--surface-2` | `oklch(0.252 0.016 256)` | `oklch(0.965 0.004 256)` |
+| `--surface-3` | `oklch(0.292 0.018 256)` | `oklch(0.93 0.006 256)` |
+| `--border` | `oklch(0.318 0.018 256)` | `oklch(0.892 0.008 256)` |
+| `--border-strong` | `oklch(0.4 0.022 256)` | `oklch(0.82 0.012 256)` |
+| `--ink` (body text) | `oklch(0.945 0.006 256)` | `oklch(0.26 0.014 256)` |
+| `--muted` (secondary) | `oklch(0.722 0.014 256)` | `oklch(0.47 0.016 256)` |
+| `--faint` (tertiary/decorative) | `oklch(0.58 0.014 256)` | `oklch(0.62 0.016 256)` |
+| `--accent` / `--live` | `oklch(0.83–0.84 0.16–0.17 152)` | `oklch(0.6 0.15–0.16 151)` |
+| `--accent-ink` (text on accent) | `oklch(0.2 0.03 256)` | `oklch(0.99 0.01 152)` |
+| `--danger` | `oklch(0.72 0.18 25)` | `oklch(0.55 0.21 27)` |
+| `--warn` | `oklch(0.82 0.14 85)` | `oklch(0.66 0.15 75)` |
+
+Body and secondary text meet WCAG AA (≥4.5:1) against their surface in both
+themes; `--faint` is reserved for decorative/large use only. Status never relies
+on color alone — a running dot pulses and is filled; a dead session is a hollow
+ring **and** carries an "exited" badge.
+
+Tints/glow derive from the accent at low alpha: `--accent-tint` (0.12),
+`--accent-ring` (focus, ~0.55), `--live-glow` (status halo).
+
+## Typography
+
+**Monospace is the UI typeface** (brand identity), system-stack only (offline-
+safe, zero web-font dependency, embedded clean into the web binary):
+
+- `--font-mono`: `ui-monospace, "SF Mono", "Cascadia Code", "JetBrains Mono", "Roboto Mono", Menlo, Consolas, monospace` — chrome, labels, data, ids, the wordmark.
+- `--font-sans`: `system-ui` stack — reserved for the few prose strings (empty-state sentences).
+
+Fixed rem scale (product register; not fluid/clamped): `--fs-11` 0.6875rem
+through `--fs-20` 1.25rem, in ~1.12–1.2 steps. Base body `--fs-15` (0.9375rem),
+line-height 1.45. No display sizes — the largest type is the 1.25rem wordmark.
+
+## Spacing, radius, sizing
+
+- Spacing scale: `--sp-1`..`--sp-8` = 4 / 8 / 12 / 16 / 20 / 24 / 32 px.
+- Radius: `--r-1` 6 · `--r-2` 9 · `--r-3` 14 · `--r-pill` 999.
+- Touch/row sizing: `--row-h` 46, `--control-h` 38, `--tap` 40 (mobile-first
+  touch targets).
+
+## Motion
+
+State and feedback only; 120–240 ms, ease-out (`cubic-bezier(0.22,1,0.36,1)`),
+no bounce. Tokens `--dur-fast`/`--dur`/`--dur-slow`.
+
+- Living signals: brand dot + running-status ripple pulse (the "alive" cue);
+  `connecting` state pill pulses.
+- Interaction: row hover/focus, button press (1px), input focus ring, chevron
+  rotation, theme-toggle sun/moon swap.
+- Every animation has a `prefers-reduced-motion: reduce` path (pulses off,
+  transitions near-instant).
+
+## Layout & structure
+
+Mobile-first, structural responsiveness (not fluid type). Single `≤520px`
+breakpoint stacks the header (full-width search, wrapped actions). A faint
+slate grid texture sits on `--bg` as terminal atmosphere (very low contrast,
+not decoration).
+
+## Components
+
+Three surfaces, all DOM built in TS, styled by class:
+
+- **Catalog** — sticky blurred header (pulsing wordmark, search, theme toggle,
+  Spawn); status bar (`N sessions · M live` tally); session tree (collapsible
+  directory folders with counts, leaf rows with status dot, name, command meta,
+  exited badge, reveal-on-hover kill). Empty states are distinct and teach:
+  no-sessions, no-search-match.
+- **Attach** — header (back, `session <id>`, live/closed/error state pill) over
+  a framed dark xterm with a green cursor.
+- **Draft pane** — the spawn form mounted inline in an empty split pane,
+  focusable like any session pane; mono inputs with green focus ring; grouped
+  worktree fieldset. Spawn opens one (reusing an empty focused pane, else
+  splitting), and "Spawn similar" seeds one from a session's dir + command.
+
+Interactive elements ship default / hover / focus-visible / active / disabled
+states; the accent green is used only for action, selection, focus, and live
+status — never decoration.
+
+## Dev review aids (DEV-only, stripped from production)
+
+`web/src/mock.ts` + query params seed a representative catalog without a running
+daemon: `?mock` (seed sessions), `?mock&spawn` (open a draft pane),
+`?theme=light|dark` (pin a theme). Guarded by `import.meta.env.DEV`.

+# Product

+## Register
+
+product
+
+## Users
+
+A single technical operator (a developer) managing every interactive shell and
+agent — Claude Code, opencode, plain bash — running on a machine. The
+job-to-be-done: from any device (laptop, desktop, **phone**), get an accurate
+at-a-glance picture of all live sessions on that host, then attach to one and
+drive its terminal. Usage is often glance-and-go: checking on a
+long-running agent, killing a stray session, or hopping into a shell mid-task.
+Mobile-first is a hard requirement — touch targets, viewport-fit safe areas,
+and bottom-sheet modals already reflect this.
+
+## Product Purpose
+
+Maestro is a terminal-session orchestrator: one place to see and attach to
+every interactive session running on a machine. tmux for persistence,
+WebSocket for transport, one daemon per host. The web UI is the browser face of
+that system — it renders the session catalog and provides the attach terminal
+(xterm.js). Success = the operator trusts the picture is accurate and
+current, and can get from "open the page" to "typing in the right session" in
+seconds, on any device.
+
+## Brand Personality
+
+Three words: **precise, calm, alive.** This is infrastructure tooling — it must
+read as trustworthy and exact, never toy-like — but it watches living
+processes, so status must feel present and current, not static. Voice is terse
+and technical, matching the CLI and the repo's terse house style. It is a
+craftsman's tool: opinionated, monospace-literate, with quiet personality
+rather than decoration. Emotional goals: in control / confident, fast /
+efficient, calm / uncluttered, with earned moments of delight.
+
+## Anti-references
+
+- Generic Tailwind-admin / SaaS-cream dashboards.
+- Heavy gradients, glassmorphism, glass cards as decoration.
+- Playful, rounded, "friendly app" aesthetics that undercut the
+  infrastructure-tool trust.
+- Whitespace-maximalist layouts that trade away the at-a-glance scan for
+  "elegance."
+- Anything where you could guess the design from the category alone
+  ("terminal tool → CRT-green-on-black novelty"): the orchestrator identity is
+  earned through restraint, not costume.
+
+## Design Principles
+
+1. **The scan is the product.** Optimize for instant comprehension of "what's
+   running, where, and is it healthy" across many sessions. Status legibility
+   beats everything else.
+2. **Calm under load.** Stay uncluttered whether there are 3 sessions or 300;
+   hierarchy and grouping carry the weight, not color-shouting every row.
+3. **Fast and keyboard-literate.** Low-friction, efficient, gets out of the
+   way; honor keyboard navigation, don't make the operator hunt.
+4. **Monospace as identity.** Treat the mono/sans pairing as deliberate brand
+   typography, not just terminal output. Ids, paths, counts, and state read as
+   precise technical data.
+5. **Earned delight.** Personality lives in motion and micro-detail (live-status
+   pulse, attach transitions, cursor cues), never in noise — always craft.
+
+## Accessibility & Inclusion
+
+Standard good practice, applied rigorously: WCAG AA contrast for all text and
+status, visible keyboard focus on every interactive element, and a full
+`prefers-reduced-motion` alternative for every animation. Status must never rely
+on color alone (pair the dot with a label/shape). Dark and light themes are
+equal citizens, driven entirely by CSS custom-property tokens.

+//! Git-toplevel probe for the spawn-form worktree section (#25).
+//!
+//! When the user picks a working directory, the spawn form wants to offer a
+//! "git worktree" toggle that needs only a branch name — the `base_repo` is
+//! *inferred* from the chosen dir rather than typed. This module answers that
+//! one question: "what git repository, if any, encloses this path?"
+//!
+//! [`find_root`] walks up from a path to the nearest ancestor containing a
+//! `.git` entry and returns that ancestor (the repo toplevel). A regular `.git`
+//! directory and a `.git` *file* (the linked-worktree / submodule form) both
+//! count, so a dir that is itself inside a checked-out worktree still resolves
+//! to its worktree toplevel.
+//!
+//! It's a pure filesystem walk with no `git` subprocess — same shape as
+//! [`crate::dirlist`]: unit-tested in isolation, and the HTTP handler /
+//! HTTP layer (#26) just wraps its `Option` for the wire.

+/// marker, matching what `git rev-parse --show-toplevel` would resolve. `start`
+/// itself is checked first, so passing a repo root returns that root.

+//! Durable per-host spawn history for the spawn form's "recent dirs" picker (#24).
+//!
+//! Sidecars are deleted on kill, so they can't back a "recently used working
+//! directories" list. This module keeps an **append-only JSONL log** at
+//! `<state_dir>/spawn-history.jsonl`, one [`SpawnHistoryRecord`] per successful
+//! spawn, that survives kills and daemon restarts.
+//!
+//! - **Write:** [`SpawnHistory::append`] adds a line. Best-effort — callers
+//!   ignore the error so a log-write failure never fails a spawn.
+//! - **Read:** [`SpawnHistory::recent_dirs`] folds the log newest-first, dedups
+//!   by `cwd`, drops entries past the recency cap, and caps the result count.
+//! - **Prune:** [`SpawnHistory::compact`] rewrites the file dropping records
+//!   past the recency cap; it's called opportunistically from `append` once the
+//!   file grows past [`COMPACT_THRESHOLD_BYTES`].
+//!
+//! The recency cap comes from `[daemon].spawn_history_days` (default 30); `0`
+//! disables history entirely — `append` and `recent_dirs` both become no-ops.
+//!
+//! Like [`crate::dirlist`] / [`crate::gitroot`], the time-dependent logic is
+//! factored into `*_as_of(now)` helpers so the fold/prune behaviour is
+//! unit-tested deterministically without touching the wall clock.

-//! Cookie-based auth for the client-facing HTTP/WS surface.
-//!
-//! On the first request the registry sets an httpOnly cookie whose value is a
-//! JWT signed with the shared token (`MAESTRO_TOKEN`, HS256). Subsequent requests
-//! must present a cookie whose signature verifies; missing or tampered
-//! cookies get a fresh cookie issued (effectively re-bootstrapping a
-//! first-time client) and are still allowed through. The cookie is the second
-//! factor against anyone routing to the bind address; per spec §Auth the
-//! perimeter is the operator's network.
-//!
-//! Implementation notes:
-//!
-//! - We reuse `jsonwebtoken` so we don't pull in a cookie/HMAC crate just for
-//!   this one signature.
-//! - The middleware passes the inbound `Cookie` header through to the inner
-//!   handler unchanged, and adds a `Set-Cookie` response header if the inbound
-//!   cookie was missing or invalid.

+//! `CatalogStore` — the TUI's view of the session list.
+//!
+//! Backed entirely by the daemon's `WS /api/events` stream:
+//!
+//! 1. The first frame after connect is a [`CatalogEvent::Snapshot`] — that's
+//!    the bootstrap. No separate REST round-trip needed.
+//! 2. Subsequent frames are deltas (`SessionAdded`, `SessionUpdated`, …) that we
+//!    apply atomically and bump a monotonic version counter.
+//! 3. On WS disconnect: exponential backoff (1s → 30s, ±25% jitter); the next
+//!    connect resends a fresh `Snapshot` so we converge without needing
+//!    server-side replay.
+//! 4. `Lagged { skipped }` from the broadcast queue is logged at warn level
+//!    and ignored — the server will re-snapshot on its own bookkeeping; for
+//!    safety we trigger a self-reconnect so the next Snapshot reconciles us.
+//!
+//! Cloneable and `Send + Sync` — pass it to the render loop and to a Tokio
+//! task that drives [`CatalogStore::run_events_loop`].
