Ship ProdDash as one app: its own Node, its own copy, a .dmg

Installing is dragging ProdDash to Applications. The app carries the
dashboard and the Node that runs it, so nothing has to be installed first and
nothing can go missing underneath it.

  ProdDash.app/Contents/
    MacOS/ProdDash            the launcher
    Resources/node/bin/node   Node 24.21.0 LTS, fetched and checksum-verified
    Resources/app/            server.js, public/, modules/

Everything mutable stays where it already was, in ~/Library/Application
Support/ProdDash — and that now includes app/, the copy of ProdDash that
actually runs. The copy is not ceremony: ProdDash updates itself in place,
and nothing may write inside a signed .app. So the bundle holds a read-only
baseline and the data directory holds the running copy, which means both
routes to a new version keep working and don't fight — installing a newer
.app replaces the copy, while a copy that has already updated itself past the
bundle is left alone.

build.sh now assembles all of it: fetches Node against nodejs.org's published
checksums (cached in .cache/), embeds the server, compiles each module's
native helper so the Mac running ProdDash needs no compiler, signs nested
code before the bundle, and builds the disk image. --dev skips the payload
for launcher work, which still runs against a checkout.

Signing is set up for a Developer ID with the hardened runtime and
notarisation (--notarize), and falls back to ad-hoc when no such certificate
is installed. Entitlements are split by what each binary actually does: JIT
for node, audio input for the launcher and for module helpers that read one.

Built and run end to end: first-run install, bundled node, dashboard and
admin serving, re-seed in both directions (newer app replaces an older copy;
an updated copy survives), disk image mounts and its app verifies.

+permission is silently absent rather than refused: an LTC input reads as

+  { "kind": "microphone",    "reason": "Decoding SMPTE LTC timecode from an audio input on this machine" },

+| `local-network` | The module talks to gear on this building's network. Not needed for services out on the internet — Planning Center, say. |

+permission; modules giving the same reason are listed together. A bare `"permissions": ["microphone"]` works when
+the standing explanation is enough. A `kind` the launcher doesn't manage is
+still listed, so nothing goes unmentioned — the shell itself ignores the key
+entirely, and other platforms ignore it too.

+# ProdDash for macOS
+
+The Mac application: a menu-bar app that carries the dashboard, its own Node
+runtime, and the permissions its modules need. Installing it is dragging
+**ProdDash** to Applications — nothing else has to be present on the machine,
+and nothing can go missing from under it.
+
+Build it with `./build.sh`. The app is native Swift with no dependencies of
+its own; the Node it ships is fetched from nodejs.org at build time and
+checksum-verified.
+
+## What's in the bundle
+
+```
+ProdDash.app/Contents/
+  MacOS/ProdDash            the launcher (Swift, ~1 MB)
+  Resources/node/bin/node   the Node runtime ProdDash runs on
+  Resources/app/            server.js, public/, modules/ — ProdDash itself
+```
+
+Everything mutable lives outside, in `~/Library/Application Support/ProdDash`:
+module config, layouts, modules installed from the admin page — and `app/`,
+the copy of ProdDash that actually runs.
+
+**Why a copy, when the bundle already has one.** ProdDash updates itself: the
+admin page's **Update now** downloads a new version and writes it over the app
+folder. Nothing may write inside a signed `.app` without breaking its
+signature, so the bundle carries a read-only baseline and the data directory
+carries the copy that runs. Both routes to a new version work, and they don't
+fight: installing a newer `.app` replaces the copy, while a copy that has
+already updated itself past the bundle is left alone.
+
+## Why it exists
+
+**Permissions.** macOS grants privacy permissions to the *application* that
+owns a process, and a child inherits its parent's identity. Started from here,
+node — and the Timers module's `ltc-capture` — belong to this app bundle, so
+the microphone and local-network prompts are asked, and remembered, as
+ProdDash. Started over SSH or from a bare launchd job there is nobody to ask:
+the permission is silently absent rather than refused, which is the "endless
+zeroes, no error" failure `ltc-listener.js` warns about.
+
+**Supervision.** The shell was built for this: with `PRODDASH_LAUNCHER=1` it
+exits **75** instead of respawning itself when the admin page applies an
+update, which the launcher reads as "start me again" rather than as a fault.
+A crash gets a backed-off restart (1s, 2s, 5s, 10s); four in two minutes stops
+the cycle rather than spinning forever.
+
+## Build
+
+```bash
+./build.sh                 # build/ProdDash.app — the whole application
+./build.sh --dmg           # …and build/ProdDash-<version>-arm64.dmg
+./build.sh --install       # …and copy it to /Applications
+./build.sh --run           # …and open it
+./build.sh --notarize      # with --dmg: notarise and staple (Developer ID)
+./build.sh --dev           # launcher only: no Node, no server — runs against
+                           # the checkout. Seconds, for work on the launcher.
+```
+
+Needs the Xcode command line tools (`xcode-select --install`) and macOS 13 or
+newer. The first build downloads Node (~50 MB) into `.cache/` and reuses it.
+A full build takes about ten seconds and produces a 117 MB app, 43 MB
+compressed in the disk image.
+
+Builds for **Apple Silicon**. To change that, or to move to a newer Node, edit
+`ARCH` and `NODE_VERSION` at the top of `build.sh` — the download is verified
+against nodejs.org's published checksums either way.
+
+The app icon is built from `public/icons/icon-512.png`, so ProdDash's own icon
+is the app's icon. A module's native helper is compiled during the build
+(`<name>.swift` beside a module's files becomes `<name>`), so the Mac running
+ProdDash never needs a compiler.
+
+## Signing
+
+`build.sh` uses a **Developer ID Application** certificate when one is
+installed, and signs ad-hoc when none is — which is fine on your own Macs, but
+another Mac will refuse the app until someone approves it under System
+Settings → Privacy & Security.
+
+To sign properly you need the Apple Developer Program (paid) and a Developer
+ID certificate — note this is not the same as the "Apple Development"
+certificate Xcode creates for you:
+
+1. Xcode → Settings → Accounts → your team → **Manage Certificates** →
+   **+** → **Developer ID Application**. (Requires Account Holder or Admin
+   on the team.) `security find-identity -v -p codesigning` should then
+   list a `Developer ID Application: …` identity.
+2. Store notarisation credentials once, with an app-specific password from
+   [appleid.apple.com](https://appleid.apple.com):
+
+   ```bash
+   xcrun notarytool store-credentials proddash --apple-id you@example.com --team-id TEAMID
+   ```
+
+3. `./build.sh --notarize`
+
+Then the disk image opens by double-click on any Mac, with no warnings.
+`CODESIGN_IDENTITY` overrides the certificate; `NOTARY_PROFILE` overrides the
+keychain profile name.
+
+## Using it
+
+The menu-bar icon is ProdDash's 2×2 tile mark; the accent tile is lit green
+while the server runs, amber mid-move, red when something needs a person, and
+hollow when it is stopped. Its menu has the whole app in it:
+
+- **Open Dashboard** / **Open Admin** — the running server, in a browser.
+- **Start / Stop / Restart ProdDash**.
+- **Launcher…** — the window below.
+- **Open at Login** — a login item, through the modern `SMAppService` API.
+- **Quit ProdDash** — stops the server too, and asks first while it is
+  running.
+
+The window has the status, both addresses the dashboard answers on, and three
+tabs:
+
+- **Log** — everything the server prints, plus what the launcher did and why.
+  Also written to `~/Library/Logs/ProdDash/proddash-<date>.log`, kept a week.
+- **Settings** — the port, and how it starts (at login, server on open,
+  restart on crash, open a browser, show this window). It also shows which
+  copy of ProdDash is running, which node, and where settings are kept.
+- **Permissions** — one line per permission: a status dot, its name, and the
+  one thing you can do about it. See below.
+
+### Port
+
+The port belongs to ProdDash, not to the launcher, so it is written to
+`proddash.json` in the data directory — the file the server already reads.
+Set it here and ProdDash keeps that port however it is started next. Changing
+it while the server runs restarts it.
+
+### Permissions
+
+What appears is what the installed modules declare in their manifests
+(`"permissions": [ … ]` — see
+[docs/MODULE-GUIDE.md](../../docs/MODULE-GUIDE.md)); hover a row to see which
+module asked, and why.
+
+- **Microphone** — asked for directly, with the status macOS reports.
+- **Local Network** — macOS has no API that reports whether this was granted,
+  so **Check Access** asks the network instead: it browses for Bonjour
+  services (which is what raises the prompt) and tries every upstream the
+  admin page is pointed at. Nothing answering, when the gear is on, means
+  macOS is withholding access.
+- **Notifications** — the launcher's own, so a server that stops while nobody
+  is watching still reaches someone. Turn them off for ProdDash in System
+  Settings if you'd rather not have them.
+
+On first run the launcher asks for what the modules declare, while someone is
+still at the keyboard, rather than halfway through a service.
+
+## Details worth knowing
+
+- **One instance.** Opening a second copy raises the first one's window.
+- **Port already in use.** If something already holds the port, the launcher
+  asks before doing anything. When that something answers like ProdDash — an
+  SSH-started copy, say, with no microphone access — it offers to take the
+  port over.
+- **Stopping is thorough.** The server is spawned into its own process group,
+  so stopping it also stops anything it started. An orphaned `ltc-capture`
+  would otherwise hold an audio device until someone found it in Activity
+  Monitor.
+- **Signals.** `killall ProdDash`, a logout or a shutdown stops the server
+  first rather than leaving node running.
+- **Nothing is required outside the app.** A development build (`--dev`)
+  carries no server and no Node, and runs the checkout it was built in with
+  whatever node is on the machine — Settings → ProdDash folder points it
+  somewhere else.
+
+## Troubleshooting
+
+| What you see | What it means |
+| --- | --- |
+| "ProdDash can't be opened because Apple cannot check it" | The app is ad-hoc signed. System Settings → Privacy & Security → **Open Anyway**, once. Signing it properly (above) removes this. |
+| "ProdDash stopped 4 times in two minutes" | The server is failing on startup — the Log tab has its own error. |
+| LTC shows no signal | Permissions tab → Microphone. If it says granted and the input is still silent, the server may be an older copy started outside the app — Stop, then Start. |
+| Nothing on the network answers | Permissions tab → **Check Access**. |
+| A development build says it can't find ProdDash | `--dev` builds need a checkout: Settings → ProdDash folder. |

+ Two kinds of setting live in this app, and they are deliberately kept apart:
+
+ * **ProdDash settings** (the port) belong to ProdDash, so they are written
+   where ProdDash already looks for them — `proddash.json` in the per-machine
+   data directory. Start the server any other way (`Start ProdDash.command`,
+   a terminal) and it still comes up on the port set here.
+ * **Launcher settings** (auto-start, restart-on-crash, where the checkout
+   lives) belong to this app and live in its own preferences.
+
+ The data-directory and port rules mirror server.js exactly — if that file's
+ `resolveDataDir` / `PORT` logic changes, change it here too.

+ a burst of fast crashes stops the cycle rather than looping forever.
+
+ Starting the server from this app is also what gives the modules their

+ parent, so node — and the `ltc-capture` tool the Timers module runs — inherit
+ this app bundle's identity, and the microphone and local-network prompts are
+ asked, and remembered, in ProdDash's name. A server started over SSH or from
+ a bare launchd job has no such identity, which is why its LTC input is
+ silently all zeros.
