feat(maestro): skip the tmux probe on a detected host reboot

Recovery could not tell a daemon restart from a host reboot: both looked like "some sessions were not in tmux list-sessions", so the tmux probe ran unconditionally and the logs said nothing useful when it was actually a reboot. Record /proc/sys/kernel/random/boot_id in the state directory on every recover(). When it differs from the stored value, every session from the previous boot is provably dead, so the tmux probe is skipped and the second recovery pass registers them dormant directly, logging "host rebooted, sessions dormant" with the count. A missing stored value or an unreadable boot id (non-Linux, restricted /proc) falls back to today's probe-based recovery. The boot id source is injected via a BootIdSource trait so tests can simulate a changed or unreadable boot id without rebooting the machine. Refs #164

+
+**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.**
+Gitea issues on [`naps62/maestro`](https://git.naps.pt/naps62/maestro), grouped
+into milestones.

-`.claude/linear.json` wires `/yolo` and `/work` to this project — they pick from "available now" (status backlog/pending, not blocked).
+`.claude/linear.json` (legacy filename, `tracker: gitea`) wires `/yolo` and
+`/work` to that tracker — they pick from open, unassigned issues whose
+dependencies are all closed. `/blitz <milestone>` sweeps a whole milestone.

-## Repo layout (target)
+Labels carry one value per axis: `area/*`, `type/*`, `difficulty/*`.
+`difficulty` drives model selection downstream, so it tracks the shape of the
+work, not its size.

-Cargo workspace, populated incrementally starting with NAP-211:
+## Repo layout
+
+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` / `web`, default = all four).

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

+`docs/WORKTREES.md` is the contract for session worktrees — placement,
+collisions, what blocks a kill, and what `--force` leaves behind. 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.
+
+`docs/PREVIEW.md` is the contract for what the content pane shows while the
+operator moves the sidebar highlight — what a preview may touch, what ends it,
+what commits it. Read it before changing sidebar-driven navigation.
+
+`docs/RESTART.md` is the contract for what clients do when the daemon restarts
+or is upgraded under them — the build stamp on `/api/info`, the status
+indicator's states, the blocking overlay, grace and poll timings. Read it
+before changing reconnect behaviour on either client.
+
+`docs/COMMAND-BAR.md` is the contract for the `ctrl-k` command bar in both
+clients — how it opens, the sigils, the key model, the match-and-rank algorithm
+the two matchers must agree on, and the fixture table they are tested against.
+Read it before changing either bar or either matcher.
+
+`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.
+- **Spawn modal** — the spawn form in a centered dialog (a bottom sheet below
+  600px) over a blurred backdrop; mono inputs with green focus ring; grouped
+  worktree fieldset. Escape, Cancel, ✕ and a backdrop click all dismiss it.
+  Submitting gives the new session its own tab; "Spawn similar" seeds the form
+  from a session's dir + command and puts the result beside it.
+
+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 the spawn modal),
+`?theme=light|dark` (pin a theme). Guarded by `import.meta.env.DEV`.

+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.

+//! Naming a session after its first prompt (#131).
+//!
+//! A session spawned without a name carries one of the daemon's own handles,
+//! marked [`NameSource::Generated`] — provisional, dimmed by both sidebars.
+//! The first prompt an agent reports to `POST /api/sessions/:id/prompt`
+//! replaces it with a name derived from that prompt, and the session settles
+//! at [`NameSource::Haiku`]. Only the first prompt does this: a session names
+//! itself once.
+//!
+//! The name is produced by running `claude -p --model haiku` on this machine —
+//! the daemon has no API key, makes no outbound HTTP request, and reuses
+//! whatever authentication the operator's own CLI already has. Everything here
+//! is best-effort: a missing binary, a timeout, or an unusable answer leaves
+//! the generated handle in place.
+//!
+//! The prompt is a user's own text, and it is handled as data throughout. It
+//! goes to the child on stdin (never argv, where it would be visible in the
+//! process table), it is never logged, and whatever comes back is reduced to
+//! a short slug by [`clean`] rather than trusted as a name.

+//! *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.

-//! Daemon-local fan-out of `RegistryEvent`s for the `WS /api/events`
-//! endpoint (NAP-248).
-//!
-//! Two sources feed this bus:
-//!
-//! 1. **Own-session events** — the daemon's `SessionManager::events()` stream,
-//!    translated from `SessionEvent` into the matching `RegistryEvent` variant
-//!    by [`spawn_session_publisher`].
-//! 2. **Peer-catalog events** — applied to the daemon's [`CatalogMirror`] when
-//!    the registry fans them out (NAP-246). `CatalogMirror::apply` publishes
-//!    each event here after mutating its local view.
-//!
-//! Subscribers get the merged stream. The `WS /api/events` handler builds a
-//! one-shot `Snapshot` of own ∪ peer state on connect, then forwards live
-//! deltas until the client disconnects. `Lagged` follows the registry's
-//! existing convention — clients resync via REST.

+//! 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.

+//! What size the shared tmux window should be, given every client watching it.
+//!
+//! A tmux window has one size, but a session can have several clients attached
+//! at once — two browser panes, a browser and the TUI. Each reports the size
+//! *it* can display, and applying whichever arrived last makes the window
+//! flip-flop. Every flip forces a full-screen application (Claude Code, vim) to
+//! repaint at a new height, and the rows it drew at the old height are never
+//! cleared: the operator ends up looking at a stale input box, types into a
+//! box that is not where the screen says it is, and concludes the pane is
+//! stuck.
+//!
+//! So the window is sized to the smallest attached client on each axis — the
+//! same rule tmux uses for its own multiple clients, and the only size every
+//! client can render without truncation. The size last handed to tmux is
+//! remembered, so a report that changes nothing costs no `tmux` fork at all.

+//!   daemon failure escape (short curl timeout, status ignored).
+//! * [`install`] — idempotent registration of that script in
+//!   `~/.claude/settings.json`. Only entries maestro itself wrote (identified
+//!   by [`HOOK_MARKER`]) are touched; every other hook and every other field
+//!   in the file is preserved verbatim.

-//! 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.
