Merge pull request 'Shell 1.13.0: the Layouts menu lists the tiles a layout holds but the board is not showing, with a ✕ to remove each' (#46) from claude/layouts-menu-not-shown into main

A tile whose module stopped offering its picker entry — Slack's Send message
and Quick replies since the Send Message module took them over — kept its
place in the layout and drew nothing, as designed, but still held its grid
cells with no control anywhere to let them go: a dead area the operator
could not place anything in.

The Layouts menu now has a Not shown section, present only while the layout
holds such a tile. One row per tile: its title (or the module's name plus
the variant, or the module id when it is not installed), why in a few words
— "not offered right now", "module disabled", "module needs a newer
ProdDash", "module not installed" — and a drawn ✕ with a tooltip that
removes it, saves the layout and frees the cells, leaving the menu open as
the Grid Size stepper and Alerts do. The section repaints while the menu is
open whenever tiles become offered or stop being, and only when the list
changed. A tile that merely waits for its module keeps its place as before.

GET /api/modules also returns `inactive` — the installed modules that are
not running, id, name and reason only — so a dashboard can tell a disabled
module from one that is not installed. The toast after loading a named
layout now says the Layouts menu can remove the tiles it did not show.
README and the module guide updated.

+pickers for each level, with a swatch running that level's cadence, and a

+# ProdDash Alerts
+
+A module that sees something a tech must act on *now* — a timer overrun,
+a meter past its limit, timecode gone — raises an **alert**, and every
+dashboard listening to its channel flashes until it is over. This page is
+the whole feature: what an operator sees and sets, and what a module does
+to raise one. The module-side contract also lives in the
+[Module Guide](MODULE-GUIDE.md#raising-alerts), which is the authority on
+how modules are written.
+
+## What an alert looks like
+
+On a dashboard that listens to the alert's channel:
+
+- The **menu bar** flashes between two colours, with the alert's text in
+  bold across its middle (and a small boxed number saying which channel it
+  came on). If the bar was hidden — by its notch, or because the screen is
+  in fullscreen — it comes out for the alert and goes back when it ends.
+- A **frame round the whole screen** flashes with it, so a fullscreen wall
+  where the bar is the only chrome still carries the flash to its edges.
+- For **low** and **medium**, that is all: the tiles and the board they sit
+  on are left alone. A **critical** alert floods the **board behind the
+  tiles** as well — in a muted cut of its two colours, mixed well toward the
+  page background and showing faintly through the tiles' own panels — so
+  the flash reaches the middle of a screen the tiles cover entirely, while
+  everything written on a tile keeps its contrast. A module's content is
+  never recoloured.
+
+The **level** sets the cadence. The two colours each level flashes between
+are the admin's choice (below).
+
+| Level | Cadence | For |
+| --- | --- | --- |
+| **Low** | a slow fade between the two colours, about three seconds a cycle; bar and frame only | something to know about |
+| **Medium** | a faster fade, about one second a cycle; bar and frame only | something to deal with soon |
+| **Critical** | no fade — the colours snap, twice a second; bar, frame and the board behind the tiles | something to deal with now |
+
+When several alerts a dashboard listens to are on at once, the bar shows
+the most severe (the newest among equals) and a **+1** says how many more
+there are.
+
+## Channels
+
+There are **six channels**, numbered 1 to 6, and nothing else: a channel
+carries no meaning of its own. A booth gives them meaning — "1 is the
+stage, 2 is video, 3 is the lobby" — by pointing modules at them (a module
+that raises alerts makes its channel an admin setting) and by choosing
+which channels each dashboard listens to.
+
+**Choosing channels:** on the dashboard, open the Layouts menu (the grid
+icon) and the **Alerts** row — it says which channels this screen listens
+to and opens to six numbered buttons that toggle them. The choice is part
+of the arrangement, like the grid size and auto-hide: it saves with this
+browser's layout and with a named layout on the server, so a booth that
+loads its "Stage" layout gets the stage's channels with it. A fresh
+dashboard listens to nothing.
+
+## One alert per channel
+
+A channel shows one alert at a time. A new alert on a channel replaces
+whatever was on it, whoever raised it; clearing a channel ends whatever is
+on it. Two modules pointed at one channel will talk over each other — give
+them channels of their own.
+
+An alert ends when its **duration** runs out (1 to 600 seconds; 15 when the
+module gives none), or when the module that raised it clears it early, or
+when that module stops (a disable, an uninstall, a config save that re-inits
+it): a module's alerts never outlive it. A module may hold an alert **until
+cleared** (duration 0) for a condition it will notice ending — timecode
+lost, a feed down — and clear it when the condition does.
+
+## Admin → Alerts
+
+The admin page's **Alerts** section (folded by default, near the bottom)
+holds two colour pickers per level — the two colours that level flashes
+between — with a swatch beside each row running that level's cadence, so a
+pair can be judged before it is tried. A change saves when the picker
+closes and reaches every open dashboard at once. The row below sends a
+**test alert** of any level on any channel: eight seconds of whatever the
+dashboards listening to that channel will see.
+
+The colours are kept as `alerts.colors` in the data directory's
+`proddash.json` (see the README's *Where settings are kept*); they hold
+across restarts and updates. The defaults are a blue pair for low, amber
+for medium and red against near-black for critical.
+
+## For module authors
+
+Raise from the server entry, which is where a condition is usually noticed
+— `shell.alert({ channel, level, text, duration })` and
+`shell.clearAlert(channel)` on the `shell` object `init()`, `routes()` and
+`tiles()` receive — or from a tile with `moduleApi.alert(...)` and
+`moduleApi.clearAlert(...)`, which go through the server. The fields, what
+each is for, and the rules that keep alerts worth looking at (raise on the
+transition, make it a setting, it is not a status) are in the
+[Module Guide](MODULE-GUIDE.md#raising-alerts).
+
+## The HTTP API
+
+Everything above rides on three public routes and two admin ones. They are
+open to anything that can reach ProdDash, like a module's own routes:
+an alert is a flash on screens in this building and nothing more.
+
+| Route | Does |
+| --- | --- |
+| `GET /api/alerts` | `{ channels: 6, levels, colors: { low: [a, b], … }, active: [ … ] }` — what is flashing and the colours. Dashboards read it on load and whenever their stream reconnects. |
+| `POST /api/alerts` | `{ channel, level, text, duration?, source? }` as `application/json`. Answers `200 { ok, alert }` or `400 { error }` saying what was wrong. `source` is the module id (anything else is recorded as `api`). |
+| `DELETE /api/alerts/<channel>` | Ends the alert on that channel. `{ ok, cleared }` — `cleared` is false when nothing was on it. |
+| `POST /api/admin/alerts` | `{ colors: { low: [a, b], medium: [a, b], critical: [a, b] } }` — a missing or malformed colour takes its default. Behind the admin PIN. |
+| `POST /api/admin/alerts/test` | `{ level, channel }` — an eight-second test alert. Behind the admin PIN. |
+
+Open dashboards learn of changes over the shell stream (`/api/events`):
+`alert` carries an alert as raised (`{ id, channel, level, text, source,
+startedAt, duration, endsAt, remainingMs }` — a browser counts down from
+`remainingMs`, so the clocks need not agree), `alert-clear` carries
+`{ channel, id }` when one ends, and `alerts-config` carries `{ colors }`
+when the admin changes them.
+
+## Trying it
+
+With ProdDash running, from the repo:
+
+```bash
+node tools/alert.js -c 1 -l critical "LTC lost"
+```
+
+raises a critical alert on channel 1 for the default 15 seconds; `-d 0`
+holds it, `node tools/alert.js -c 1 --clear` ends it, `--list` shows what
+is on. Open a dashboard, choose channel 1 in its Layouts menu → Alerts, and
+watch; a second browser listening to channel 2 should stay quiet. The admin
+page's **Test** buttons do the same from the browser.
+`node tools/alerts.test.js` runs the server's side of all this end to end.

+### Native helpers
+
+Some features need a program JavaScript cannot be: reading an audio input,
+decoding timecode, measuring sound. Rule 3 says the module owns that program;
+this section says how it ships: **already built, for every platform it runs
+on, inside the module folder.** The machine running ProdDash is a packaged
+app or the Windows bundle plus modules from the admin page's catalog. It has
+no compiler and never will — the catalog delivers exactly the folder that is
+in the repo, so the binaries live in git next to the code.
+
+- **Platforms.** Apple silicon macOS and 64-bit Windows are required. Intel
+  macOS is welcome but optional. One file per platform in `bin/`, named for
+  what it is:
+
+  | Platform | File |
+  | --- | --- |
+  | macOS, Apple silicon | `bin/<name>-macos-arm64` |
+  | Windows, 64-bit | `bin/<name>-win-x64.exe` |
+  | macOS, Intel (optional) | `bin/<name>-macos-x86_64` |
+
+- **Pick it at runtime, and cope without it.** Choose by `process.platform`
+  and `process.arch`; when there is no file for this machine, the feature
+  says so — in `health()` and in the tile's `setStatus` — and everything else
+  in the module keeps working. Never try to build it, never look for a copy
+  elsewhere on the machine, never tell the operator to install anything.
+
+  ```js
+  const HELPERS = {
+    darwin: { arm64: 'ltc-capture-macos-arm64', x64: 'ltc-capture-macos-x86_64' },
+    win32: { x64: 'ltc-capture-win-x64.exe' },
+  };
+  const name = HELPERS[process.platform]?.[process.arch];
+  const helper = name ? path.join(__dirname, 'bin', name) : '';
+  if (!helper || !fs.existsSync(helper)) {
+    // Timecode is off on this platform. Say it once, keep the clock running.
+  }
+  ```
+
+- **One contract, any language.** Every platform's binary speaks the same
+  command line and output format, so `server.js` has one code path. What is
+  behind it is your choice per platform — Swift against CoreAudio on macOS,
+  C#, C or Rust on Windows — the module does not care.
+- **Source and build beside it.** Keep the source under `native/` with one
+  script that produces every `bin/` file from a checkout, so any binary can be
+  rebuilt from what is committed. A helper that cannot be rebuilt does not
+  ship.
+- **Bump the module version whenever a binary changes**, like any other
+  file — that is how installs learn about it.
+- **Keep them lean.** Optimised builds, no debug symbols, a few megabytes at
+  most: the catalog fetches the whole repo as one archive, capped at 80 MB.
+- **Signing.** Apple silicon refuses unsigned code, so sign the macOS binary
+  — Developer ID when you have it, ad-hoc at least. Windows needs nothing:
+  files the app writes carry no download mark, so SmartScreen never sees
+  them. Permissions come from the launcher (see "Permissions macOS has to
+  grant"), not from the binary.
+
+A helper that ends up existing for one platform only is an exception made
+on purpose, not a default: say so in the module's README and in the health
+line, so a Windows booth knows why the feature is off.

+## Raising alerts
+
+An alert is for the thing a tech must act on *now*, whichever tile they
+happen to be looking at — a timer that has overrun, a meter past its limit,
+timecode that has gone quiet mid-service. Every dashboard that listens to
+the alert's channel flashes: its menu bar (brought out for the duration,
+even if it was hidden) and a frame round the whole screen alternate between
+the level's two colours, with your text bold across the middle of the bar.
+The shell owns all of that — the colours (Admin → Alerts), the cadence,
+which screens listen (each dashboard's Layouts menu → Alerts) — so a module
+only has to say what happened. [docs/ALERTS.md](ALERTS.md) has the
+operator's side.
+
+Raise one from your server entry, where the condition is usually noticed:
+
+```js
+init({ config, log, shell }) {
+  // …when timecode drops:
+  shell.alert({ channel: config.alertChannel, level: 'critical', text: 'LTC lost', duration: 0 });
+  // …and when it is back:
+  shell.clearAlert(config.alertChannel);
+}
+```
+
+or from a tile, through the shell's server:
+
+```js
+await moduleApi.alert({ channel: 2, level: 'medium', text: 'Service over by 5:00', duration: 20 });
+```

A channel carries no meaning of its own — the booth decides that "1 is the stage, 2 is video" — so **make yours an admin setting** (`configSchema`, `type: "number"`, `min: 1`, `max: 6`) rather than hard-coding one. |
+| `level` | `low` — a slow fade between the two colours, for something to know about; `medium` — a quicker pulse, for something to deal with soon; `critical` — no fade, the colours snap, and the board behind the tiles floods with a muted cut of them too, for something to deal with now. |
+| `text` | What happened, in a few words — 80 characters at most (more is cut, whitespace is collapsed). It is shown as given, so write it the way it should read on a wall: `SPL 102 dB — over limit`, not `spl_over_limit`. |
+| `duration` | Seconds, 1 to 600; `15` when omitted. `0` holds the alert until you clear it — for a condition you will *notice ending* (timecode lost, a feed down) and clear; a one-off event takes a duration. |
+
+Both return the alert as raised (`{ id, channel, level, text, source,
+startedAt, duration, endsAt, remainingMs }`) and throw — reject, on the
+client — with a one-line reason when the input is refused. That is a bug
+in your module, not something to show the operator.
+
+What to know:
+
+- **One alert per channel.** A new alert on a channel replaces whatever was
+  on it, whoever raised it; `clearAlert(channel)` ends whatever is on it.
+  Two modules on one channel talk over each other — one more reason the
+  channel is admin config.
+- **Your alerts end when you stop.** A disable, an uninstall or a config
+  save that re-inits you clears every alert your module raised, held ones
+  included. If the condition is still true, raise it again from `init()`.
+- **Raise on the transition, not the state.** `if (over && !wasOver)
+  shell.alert(…)` — an alert re-raised on every poll restarts its timer and
+  flashes for ever. Clear it, or let it expire, when the condition ends.
+- **Make alerting a setting**, and the threshold too: a `switch` in
+  `configSchema`, off by default unless alerting is the module's reason to
+  exist. A screen that flashes for nothing teaches a room to ignore it.
+- **It is not a status.** The tile's dot (`setStatus`) says how *you* are;
+  an alert says what the *room* must do. An unreachable upstream turns the
+  dot red; it raises an alert only if that is something a tech has to act on
+  during the service, and the operator switched that on.
+- Alerts reach the server over `POST /api/alerts` — what `moduleApi.alert`

+### Offering messaging to the Send Message module
+
+The Send Message module is the one place a dashboard sends from — a
+PIN-gated compose box and a grid of quick replies — whatever the platform.
+It owns nothing upstream: a module that *can* deliver a message (Slack posts
+to a channel, ProdCom puts typed text on a comms channel) offers that over
+its own routes, keeps its one upstream connection, and the Send Message
+module hands messages to it over loopback. A provider has no PIN, no send
+tile and no quick replies of its own; the shell's Add-tile picker shows the
+Send message and Quick replies tiles once, under Send Message.
+
+A module offers messaging by:
+
+1. Declaring it — `"provides": ["messaging"]` in `module.json`. The Send
+   Message module re-reads `/api/modules` every 30 s, so a provider installed
+   mid-session shows up without a restart.
+2. Serving `GET /messaging` — what it can send to, from state it already
+   holds (it is polled every few seconds while a send tile is open):
+
+```json
+{
+  "label": "Slack",
+  "identity": "Apollo Beach",
+  "destinationRole": "recipient",
+  "status": { "state": "ok", "message": "Apollo Beach · #production, #ops" },
+  "destinations": [
+    { "id": "C01ABC", "label": "#production" },
+    { "id": "C02DEF", "label": "#ops", "color": "#5c9de0" }
+  ],
+  "emptyMessage": "",
+  "maxChars": 4000
+}
+```
+
+| Field | Meaning |
+| --- | --- |
+| `label` | The platform's name, as the sending line and the Send as menu show it. |
+| `identity` | Who a message appears to come from when that is fixed by the connection, or `''`. Shown as "as Apollo Beach". |
+| `destinationRole` | What a destination *is*. `recipient` (the default): a message goes **to** it — a Slack channel — and the operator picks one by clicking its transcript tile, so it never appears in the Send as menu. `identity`: a message goes out **as** it — a ProdCom channel — and the Send as menu lists them; the tiles then say "Send message to ProdCom as FOH" and "Sent to ProdCom as FOH". The menu exists only while some installed platform offers identities. |
+| `status` | `ok`, `connecting` or `error` plus one line — the same thing your `health()` says. A provider in error is still listed, so the operator sees why a send will fail before trying. |
+| `destinations` | Where a message can go, or who it can go out as: a stable `id` (what `/messaging/send` receives), a `label`, and an optional `color`. Offer only what will work — ProdCom lists just the channels that accept typed text. Order is the order the menu shows. |
+| `emptyMessage` | Optional: why the list is empty, when you know ("No ProdCom channel accepts typed text — turn on typing for one in ProdCom"). The tiles show it in place of a destination. |
+| `maxChars` | The longest text you accept; the Send Message module refuses longer ones before asking you. |
+
+3. Serving `POST /messaging/send` — `{ "destination": "<id>", "text": "…" }`
+   with the browser's unlock token as `Authorization: Bearer …`. **Check the
+   token before touching your upstream**: the Send Message module owns the
+   PIN, so ask it — `GET http://127.0.0.1:${shell.port}/api/modules/send-message/verify`
+   with the same `Authorization` header answers `200 { ok: true, expiresAt }`
+   or `401`. A `404` means no Send Message module is installed or enabled:
+   refuse with a sentence that says so. Without this check, any browser on
+   the network could post as the location by calling your route directly.
+   Answer `200 { "ok": true, "label": "#ops" }` when it landed, otherwise
+   `{ "error": "<one sentence a tech can act on>", "code": "…" }` with `400`
+   (bad destination or text), `401` (the token was refused), `429` (your
+   upstream is rate-limiting) or `502` (your upstream failed). Validate the
+   destination against your own list — never pass an arbitrary id upstream.
+
+The same verification gates any other outbound action a module offers from
+its tiles — the Slack transcript's emoji reactions ride on it — so a module
+never needs a PIN of its own: one unlock serves every messaging tile on the
+page. The `slack` and `prodcom-transcript` modules are the reference
+implementations (`verifyUnlock()` in either server entry is the whole check).
+
+### Messaging on the page
+
+Where the next message goes is a fact about the whole dashboard, not one
+tile: the Send message tile, the Quick replies tile and every transcript on
+the page must agree, and they belong to different modules. Modules don't
+import each other, so the agreement lives on `window` — one plain object plus
+`CustomEvent`s on `window`, created by whichever messaging-aware tile mounts
+first:
+
+```js
+window.proddashMessaging = {
+  version: 1,
+  target: { provider: '', destination: '', providerLabel: '', destinationLabel: '', identity: '' },
+  unlock: { token: '', expiresAt: 0, reason: '' },
+  quickEmojis: [],            // the Send Message module's admin list, plain strings
+  transcripts: new Map(),     // instanceId → { provider, destination }
+  senders: new Set(),         // instanceIds of Send message / Quick replies tiles
+};
+```
+
+Events, all named `proddash:messaging:<name>` with the payload in `detail`:
+
+| Event | Who sends it | Meaning |
+| --- | --- | --- |
+| `select` | a transcript tile, or a Send as menu | `{ provider, destination }` — the operator pointed the senders here. A tile bound to one recipient (a Slack channel transcript) names it; one that shows a whole platform (ProdCom) sends `destination: ''` and the Send Message tile keeps the identity it has chosen for that platform. |
+| `target` | the Send Message tiles | `window.proddashMessaging.target` changed: where the next message goes, resolved. A transcript compares `provider` (and `destination`, when it has one) and lights its bottom edge. |
+| `unlock` | the Send Message tiles; a provider's tile on a `401` | `window.proddashMessaging.unlock` changed. Read the token from the object, never cache it; `''` means locked, with `reason` saying why. |
+| `transcripts` | transcript tiles | the `transcripts` map changed (a tile mounted, unmounted or learned its channel). Register once you know your destination; unregister in `stop()`. This is how a dashboard with one transcript sends there by default. |
+| `senders` | the Send Message tiles | the `senders` set changed — a transcript's locked note can say "add a Send message tile" rather than "enter the PIN". |
+
+A transcript tile needs only three things: emit `select` on a click in its
+body, register in `transcripts`, and toggle a target class on `target`. A
+tile that performs a gated action itself (a reaction) reads
+`window.proddashMessaging.unlock.token` and sends it as the Bearer token to
+its own module's route. The Send Message tiles save the chosen platform and
+per-platform destination in their instance settings, so a named layout
+remembers them; the page object is the live copy.

+Nothing to install. This folder holds the dashboard and its own copy of Node.
+
+1. Move this folder somewhere you can write to, for example C:\ProdDash
+   (not Program Files: updates write into this folder).
+2. Double-click ProdDash.bat. A window opens and stays open while the
+   dashboard runs; closing it stops the dashboard.
+   - If Windows warns about the file, choose More info, then Run anyway.
+   - When Windows Defender Firewall asks about node.exe, allow it on
+     private networks so other screens can reach the dashboard.
+3. Open http://localhost:24500 on this PC. Other devices on the network use
+   http://<this PC's IP address>:24500. Settings are on the admin page,
+   http://localhost:24500/admin.
+4. The bundle ships without modules. On the admin page, tick the ones this
+   PC needs under Available modules and press Install selected; each one
+   updates on its own from then on.
+
+Your settings and layouts live in %APPDATA%\ProdDash, not in this folder,
+so unzipping a new version or updating never loses them.
+
+Start with Windows: press Win+R, type shell:startup, press Enter, and put a
+shortcut to ProdDash.bat in the folder that opens.
+
+Updates: the admin page's Update now fetches the new version into this
+folder and restarts the dashboard; the window stays open. A copy of the
+version it replaced is kept for a short while in case the new one will not
+start.
