+### macOS — the app

+Open the disk image and drag **ProdDash** to Applications. That's the whole

+nothing else has to be installed and nothing can be missing. It lives in the
+menu bar, starts and stops the server, can open at login, and holds the
+permissions the modules need — the microphone the LTC listener reads, and
+local network access for ProdCom and ProPresenter. macOS grants those to the

+a launchd job) simply doesn't have them, and an LTC input goes silently to
+zeroes.

-Shell settings live in [config/proddash.json](config/proddash.json):
+### Where settings are kept
+
+Everything you enter in the admin page (module connection settings, API keys,
+enabled/disabled flags) and every named layout is written to a **data
+directory on the machine running the server** — not into the app folder:
+
+| OS | Data directory |
+| --- | --- |
+| Windows | `%APPDATA%\ProdDash` (e.g. `C:\Users\<you>\AppData\Roaming\ProdDash`) |
+| macOS | `~/Library/Application Support/ProdDash` |
+| Linux | `$XDG_CONFIG_HOME/proddash`, else `~/.config/proddash` |
+
+Because it lives outside the checkout, you can `git pull`, re-clone, or reset
+the app folder from `main` and start the new version with everything still
+configured. The admin page shows the exact path in use, and the server prints
+it at startup (`Settings : …`).
+
+The directory holds `modules.json` (module config), `layouts/` (named
+layouts) and `modules/` (modules installed from the admin page), all written
+by the app itself. Installed from the macOS app, it also holds `app/` — the
+copy of ProdDash that actually runs, laid down from inside the app bundle on
+first launch and updated in place from then on (nothing may write inside a
+signed .app, and ProdDash updates itself). It may also hold a `proddash.json`
+with this machine's shell settings — the same keys as the checked-in
+[config/proddash.json](config/proddash.json), which supplies the defaults:

+
+### Themes
+
+The whole dashboard — every tile, on every browser — draws with one palette,
+chosen in the admin page's **Theme** section and switched live: pick a swatch
+and open dashboards change without a reload. Five presets ship: **Booth**
+(the default dark, mint accent), **Harbor** (deep navy, cyan), **Graphite**
+(neutral charcoal, electric blue), **Ember** (warm broadcast black, orange)
+and **Daylight**, a light palette for a front-of-house desk in daytime. Each
+keeps the status colours apart — the accent is never near the danger red or
+the warning amber — and muted text readable in a dark booth. The choice is
+stored as `theme` in the data directory's `proddash.json` (table above), so
+it holds across restarts and updates; a browser remembers the last theme it
+saw and applies it before the server answers, so nothing flashes. Modules
+style with the shell's colour variables, which is why they follow; a colour
+set on a tile itself (a PCO Plan header colour, say) is deliberately kept.
+
+## Installing modules and updating
+
+Everything below happens in the **admin page**; ProdDash talks to its GitHub
+repository (`michaelmcgary2008/ProdDash`, branch `main` — change with
+`repo` / `branch` in `proddash.json` or the `PRODDASH_REPO` variable,
+`owner/repo#branch`). It downloads one small archive of the branch, at most
+every few minutes, only while the admin page is open or for the update check
+below. Nothing is installed without someone clicking.
+
+- **Available modules** lists modules in the repo that aren't installed
+  here. **Install** downloads the module into the data directory's `modules/`
+  and starts it right away — nothing is written into the app folder, and no
+  restart is needed. Modules that ship with your copy of ProdDash are
+  "bundled"; ones you installed are "installed"; if both exist, the newer
+  version runs.
+- **Uninstall** on a module card removes an installed module's files. For a
+  bundled module (its folder belongs to the app) it hides the module from
+  every dashboard instead; it reappears under Available modules and can be
+  brought back without downloading. Settings are kept either way.
+- **Module updates**: when the repo has a newer version of an installed
+  module, its card shows **Update to vX**.
+- **Version requirements**: every module declares the ProdDash versions it
+  needs (`"proddash": ">=1.1.0"` in its manifest). A module that needs a
+  newer shell is listed but not loaded, and cannot be installed until
+  ProdDash is updated.
+- **ProdDash updates**: the admin page checks the repo shortly after start
+  and every six hours, and shows a banner when `main` has a newer version
+  (or new commits). **Update now** brings the app folder up to date and
+  restarts the server; dashboards reconnect on their own. A git checkout is
+  updated with `git pull --ff-only` (only when it is on the repo branch with
+  no local changes — otherwise the banner says why and you update with git).
+  A plain folder (no `.git`) has the repo archive unpacked over it; files
+  removed upstream are left behind but harmless. Settings and layouts are
+  never touched. **What changed** opens the commit comparison on GitHub.
+- **Restarting**: after an update the server exits with code 75 and starts
+  its own replacement, which waits for the port to free up. If you supervise
+  ProdDash with your own launcher, set `PRODDASH_LAUNCHER=1` so the server
+  just exits and your launcher restarts it on exit code 75.
+  `PRODDASH_NO_REMOTE_CHECK=1` turns off the periodic check (the admin page
+  still checks when opened).

+  another tile it slides to the bottom edge and the tile above grows into the

+  ProPresenter exposes no timecode over any API, so LTC is decoded from the

+  compiled on first use — and decodes the SMPTE frames in-process:
+  running/stopped/no-signal, the timecode counting frame-accurately in real
+  time, and the frame rate (incl. 29.97 drop-frame). macOS note: the
+  ProdDash server needs microphone permission — launch it from a logged-in
+  session (Start ProdDash.command) and approve the one-time prompt; a server

+  what's done and shows the elapsed vs planned runtime and how far
+  ahead/behind the service is. Admin config is the connection: Planning
+  Center credentials (Personal Access Token app ID + secret, or an OAuth
+  token), the service type (a list grouped by your Planning Center folders)
+  and an optional pinned plan. Everything about the display is per tile
+  (gear menu): the top-bar text (placeholders such as
+  `{series} • {part} | {serviceType} • {date}`), colors, text size, and a

+These are not style preferences — the admin page, the installer and the
+people running the booth depend on them.
+
+1. **All settings live in the ProdDash admin page.** Server-wide settings go

+   variable.

+   the module — or fetched by your own `init()` on first start, with the
+   admin health line saying what is happening. No `npm install`, no
+   installer, no "run this first".
+3. **Everything the module does runs inside the module.** No helper scripts,
+   companion programs, daemons or services the operator has to start next to
+   ProdDash. If your feature needs a listener, a decoder or a worker, your
+   server entry owns it: start it in `init()`, stop it in `stop()`, report
+   it in `health()`. A child process the module itself spawns and supervises
+   is fine; a program someone launches by hand is not.

+}
+```
+
+- `collapsed`: `true` (starts folded), `false` (starts open but can fold),
+  or `"whenSet"` — folded once the group already holds values (a saved
+  password, or anything other than the schema default), open while it is
+  still empty. Omit it and the group is a plain, always-open block.
+- `columns`: 2–4 lays the group's fields out in a grid — the way to keep a
+  long checklist of booleans compact.
+- `help`: guidance for the whole group. The admin page shows it as an
+  ⓘ beside the group title (click or hover to read), so a group can carry a
+  paragraph without pushing its fields down the page. Say where a value comes
+  from, not what a field is.
+- `toggle`: the key of a `switch` field in this group. It renders in the
+  group's title row, at the right, as the group's on/off; the rest of the group
+  dims while it is off, and the field is not repeated in the body. This is how
+  an integration is disabled without unmounting the module — ProPresenter
+  timers, say, on a Sunday when ProPresenter isn't running.
+
+`help` on a field puts one line of guidance under its control — allowed
+placeholders, where a value comes from. Keep labels short and put the
+explanation there.
+
+`group` and `help` work on `instanceSchema` fields too, and a manifest
+`instanceGroups` map plays the `configGroups` role for the tile's gear
+popover (`collapsed: true | false`, `columns`, `help`). That is how a module
+with a long show/hide checklist keeps the popover usable — see `pco-plan`.
+Display choices belong there, per tile; admin config is for connections.
+
+`showWhen: "<key>"` hides a field until the boolean/`switch` field named
+`<key>` is on — e.g. the audio device and channel appear only once the LTC
+listener switch is enabled. The hidden field still keeps its stored value.
+
+A `select` whose choices are only knowable at runtime (audio devices, serial
+ports, discovered sources) sets `optionsRoute` instead of — or as a fallback
+refresh of — static `options`: the admin page GETs
+`/api/modules/<id><optionsRoute>` and expects `{ "options": [ { "value",
+"label" }, … ] }` from one of the module's own server routes. The saved value
+stays selectable even when the route is down or the option has vanished. (See
+`propresenter-timers`' "Audio device" for a worked example.)
+
+An option may carry a `group`: options sharing one render under a single
+`<optgroup>`, so a tree (Planning Center folders, device classes) is
+browsable inside the select. `optionsDependsOn: "<key>"` makes the admin
+page fetch the options with that other field's current value appended as a
+query parameter (`?<key>=<value>`), now and again whenever it changes — e.g.
+a plan list that follows the chosen service type. (Both in `pco-plan`.)
+
 `password` fields are admin-config only in practice: their values are stored
-in `config/modules.json`, handed to your *server* entry, and **never sent to

 form. Anything upstream that needs the secret must go through your server
 routes.
 
-Admin config lives in `config/modules.json` (written by the admin page —

+Anything that points at a device or service on the network — ProPresenter,
+ProdCom, a camera, a mixer — must be **one `endpoint` field**, so every
+module's connection is entered the same way. The admin page renders an
+endpoint as a single "Host / IP : Port" control; the value is stored and
+handed to your server as an object:
+
+```json
+"propresenter": {
+  "type": "endpoint",
+  "label": "ProPresenter",
+  "default": { "host": "", "port": 1025 }
+}
+```
+
+```js
+// in your server entry
+const { host, port } = config.propresenter;
+const base = `http://${host}:${port}`;
+```
+
+Do **not** split host and port into separate `string`/`number` fields, and
+do **not** ask for a full `http://…` URL unless the setting genuinely is a
+web address where protocol or path matter (a page to embed, a webhook).
+Endpoints belong in admin config, not per-tile settings — connections are
+server-wide by design.
+
+Admin config lives in `modules.json` inside the server's data directory
+(written by the admin page — your module never touches that file, and it
+survives updates of the app folder). Per-tile settings live inside each
 browser's layout.
 
+### Permissions macOS has to grant
+
+Some things a module does need the operating system's permission, not just
+configuration: reading an audio input, reaching gear on the local network.
+macOS grants those to the **application that owns the process**, which for
+ProdDash is the macOS launcher (`launcher/macos`) — the server is its child,
+so the prompts are asked, and remembered, in ProdDash's name. A server
+started over SSH or from a bare launchd job has no such owner, and the
+permission is silently absent rather than refused: an LTC input reads as
+endless zeroes, a local host simply never answers.
+
+Declare what you need, and why, so the launcher's Permissions tab can list
+it and ask for it before a service rather than during one:
+
+```json
+"permissions": [
+  { "kind": "microphone",    "reason": "Decoding SMPTE LTC timecode from an audio input on this machine" },
+  { "kind": "local-network", "reason": "Reaching ProPresenter on this network" }
+]
+```
+
+| `kind` | When to declare it |
+| --- | --- |
+| `microphone` | The module reads an audio input (`ltc-capture` and anything like it). |
+| `local-network` | The module talks to gear on this building's network. Not needed for services out on the internet — Planning Center, say. |
+
+`reason` is one line, shown to the operator as-is when they hover the
+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.

+### Offering timers to the Timers module
+
+The Timers module shows timers from anywhere: ProPresenter, LTC, its own

+
+1. Declaring it — `"provides": ["timers"]` in `module.json`. The shell
+   forwards `provides` in `/api/modules`, which is how the Timers module finds
+   providers without a list anyone maintains.
+2. Serving `GET /timers` from its server routes, returning a snapshot:
+
+```json
+{
+  "source": "pco-plan",
+  "label": "PCO Plan",
+  "updatedAt": 1757800000000,
+  "timers": [
+    {
+      "id": "service",

+      "kind": "elapsed",
+      "state": "running",
+      "startedAt": 1757799000000,
+      "elapsedMs": 1000000,

+      "targetMs": 4500000,
+      "status": { "text": "Welcome & Announcements", "tone": "ok" },
+      "detail": "Item 3 of 12"
+    }
+  ]
+}
+```
+
+| Field | Meaning |
+| --- | --- |
+| `source`, `label` | Your module id, and the heading the Timers module puts over your timers. |
+| `updatedAt` | ms since epoch when this snapshot was taken. Every duration below is *as of this instant*. |
+| `id` | Stable within your module — the Timers module keys tile settings (shown/hidden, colours) on `source` + `id`. |
+| `kind` | `elapsed` (counts up), `countdown` (counts down to zero), `clock` (a time of day; put the ISO time in `status.text`). |
+| `state` | `running`, `paused`, `stopped` (finished; value frozen), `idle` (exists, hasn't started — a timer that will start at 11:00). |
+| `startedAt` | ms epoch when it last started running; the consumer extrapolates from here, so a running timer never needs a fast poll. |
+| `elapsedMs`, `remainingMs` | The values at `updatedAt`; `null` when not meaningful for the kind. |
+| `targetMs` | Planned length (elapsed) or full length (countdown), or `null`. Lets the consumer colour overruns. |
+| `status` | Optional one-liner the consumer shows beside the time — the current item, "ahead 1:20". `tone`: `ok`, `warn`, `danger`, `muted`. |
+| `detail` | Optional second line. |
+
+The consumer derives the displayed time locally from `startedAt`/`elapsedMs`
+and its own clock, so a snapshot every couple of seconds is plenty — `/timers`
+must be cheap to answer (serve from state you already hold; never call
+upstream to answer it). Optionally also serve `GET /timers/stream` as SSE
+(`event: timers`, `data:` the same object, on every change plus a heartbeat
+comment every 15 s); the consumer uses the stream when it exists and polls
+`/timers` otherwise. Only offer timers a production tech would want on a
+wall — the Timers module lets them hide any of them per tile, but every entry
+you add is a decision someone has to make.

+# 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. |

+/**
+ * Service timing for the PCO Plan module — pure functions, no I/O, no
+ * timers. server.js feeds them the plan's service times, the documents
+ * ProPresenter puts live and the clock; service-timing.test.js calls them
+ * directly. Two questions are answered here:
+ *
+ *   1. Which of a plan's services owns the clock right now?   → serviceWindows / selectService
+ *   2. When does that service count as started, and as ended? → advance
+ *
+ * ── Service windows ────────────────────────────────────────────────────
+ *
+ * A plan can have several services (plan_times of type "service": 9:00 and
+ * 11:00, say). Only ONE owns the service-elapsed clock, the current-item
+ * timing and the countdown at any moment, and moving into the next
+ * service's window resets all three. Each service's window runs from the
+ * end of the previous one to a boundary the next service's pre-roll sets:
+ *
+ *   boundary(i → i+1) = min( start[i+1],
+ *                            max( start[i+1] − preRoll, endOf[i] ) )
+ *
+ *   endOf[i] = the moment service i ended (its end cue fired), else its
+ *              scheduled end (plan_time ends_at, else start + the planned
+ *              length of the "during" items, else 90 min).
+ *
+ * In words: the next service takes over `preRoll` before its scheduled
+ * start (30 min by default; admin "Pre-roll"), but never before the current
+ * one has ended or was due to end, and never later than its own start. A
+ * service still running at the boundary is stopped there — that is the
+ * "next service's start" failsafe the end cue has. The first window opens at
+ * the beginning of time (before 9:00 the day belongs to the 9:00 service:
+ * countdown running, service idle); the last window never closes — the last
+ * service stays "stopped" until the plan itself changes (the next day's plan
+ * takes over through the plan picker). The last service also has a failsafe
+ * end: its scheduled end + LAST_SERVICE_OVERRUN_MS.
+ *
+ * ── Start and end of a service ─────────────────────────────────────────
+ *
+ * phase: idle → running → stopped, never backwards within one window.
+ *
+ *   start, schedule mode  (default)  at the scheduled start; startedAt = it.
+ *   start, document mode             when the start document goes live
+ *                                    (edge: it has to *become* live, from
+ *                                    pre-roll before the scheduled start
+ *                                    onwards — a rehearsal an hour earlier
+ *                                    that shows the same document is not the
+ *                                    service). Failsafe: if the document has
+ *                                    not gone live by start + grace (admin
+ *                                    "Start failsafe", 10 min default), the
+ *                                    service starts anyway, counting from
+ *                                    the scheduled start — the best estimate
+ *                                    of when it really began.
