Merge pull request 'Band Lineup 1.13.0: a photo per instrument, your own photos win, spots stay in reach while dragging' (#53) from claude/band-lineup-photos into main

DJ plays drums one week and sings the next; one photo can't fit both. A
person can now have a photo per instrument, named "Name - Instrument"
("DJ - Drums.jpg", "DJ - Vocals.jpg"), plus a plain "DJ.jpg" for
everything else. Sync reads the instrument family of the spot each person
lands in (its bracketed role, else their PCO position) and picks:

1. the photo picked by hand for them on that instrument;
2. a photo named for that instrument;
3. their everyday pick, else their best-named photo. A photo of them on
   another instrument still beats PCO's headshot.

Families keep the shorthands together: Vox/Vocals/Singer, Keys/Piano/Pad,
Drums/Perc, Bass, Guitar/Electric/Acoustic/Rhythm, Leader. A photo
dropped onto someone is remembered per person per instrument
("<id>|drums"), so a drum pick never overrides the vocal photo. A spot
naming several roles files under its most specific: Leader, then Vocals,
Drums, Keys, Bass, Guitar. Photo names from files now collapse the spaces
left by "Name - Instrument".

+  turn. Both are switches in the tile's gear (**Song progress**, **Song
+  sections**), and both are simply absent when there is no AbleSet module, it
+  is switched off, or it has no host — nothing to turn off and nothing to
+  explain.
+
+  **Song Key** is one value, as large as the tile allows: the key of the item
+  ProPresenter has live, with the song's name and the next key under it — both
+  switches, as is the colour. When the feed that picks the item is gone the key
+  stays up, faded, and the tile's dot says so rather than pretending to be
+  current.
+
+  Keys are written as notes wherever the module shows one: Planning Center's
+  `Bb` and `F#m` read as B♭ and F♯m, on the Plan tile's item badge and in the
+  Song Key tile alike.
+
+  **Teams** shows the same plan's team and position assignments — each team
+  as a band of its people, with their photo (fetched through ProdDash, never
+  by the browser; initials when Planning Center has none) and a dot for
+  confirmed, unconfirmed or declined. Its gear menu picks which teams and
+  which positions appear, groups people under their position or lists them
+  plainly, and sets the colours: one for the team headers, or **Tint teams**
+  to give each team its own, optionally carried into the rows. Teams nobody
+  has signed up for are hidden until you ask for them — that list comes from
+  the service type, since Planning Center only returns a team once somebody
+  is on it.
+- **Slack** — live transcripts of this location's Slack channels. The ＋
+  picker lists one transcript tile per configured channel, titled
+  `#channel`. Messages arrive with avatars, names and times, Slack's inline
+  formatting and the workspace's custom emoji; text size and jump-to-latest
+  sit in the title bar. Sending is the **Send Message** module's: a click
+  anywhere in a transcript points its tiles at that channel (the bottom
+  edge lights up in the accent color), and a message then leaves through
+  this module's one Slack connection, as the location. A right-click on a
+  message opens the reaction menu, which rides on the same unlock — with

+- **Send Message** — the one place a dashboard sends from, whatever the
+  platform. Two tiles, one of each per dashboard: **Send message**, a
+  free-text box with the admin's quick emojis one press away, and **Quick
+  replies**, a grid of preset buttons. Both go wherever the operator last
+  pointed them with a click on a Slack or ProdCom transcript. A platform
+  whose destinations are identities rather than recipients — ProdCom, where
+  typed text goes out *as* a channel — also gets a **Send as** menu in the
+  title bar listing those identities; the menu exists only while such a
+  platform is installed, and Slack's channels are never in it. The choice is
+  saved with the tile, so a named layout remembers it; the transcript it
+  points at carries the accent stripe. The module
+  owns no connection of its own — it finds every installed module that
+  offers messaging and hands the message to it over loopback — and it owns
+  the PIN: nothing leaves the machine until it is entered on one of its
+  tiles, one entry unlocks every messaging tile on that dashboard page
+  (Slack's reaction menu included) until the auto-lock idles out, a reload
+  asks again, and the lock button ends it early. The PIN pad takes taps, a
+  keyboard, or a phone's — tapping the dots raises it. The PIN can be
+  switched off for a booth that doesn't need one.

+  one to a destination — and up to eight quick emojis).
+  Tile settings: quick emojis on the Send message tile.
+- **Resi Cues** — how long until the next Resi cue point, for a campus
+  running video from another site. The tile is one number, as large as it
+  will go: the countdown to the next cue, its name above it, and the playhead
+  and the cue just passed underneath. It also offers that countdown and the
+  playhead to the **Timers** module, so they can sit among the ProPresenter
+  timers instead of in a tile of their own.
+  Both the cue list and the decoder's position come from Resi's cloud rather
+  than the decoder — the decoder reports upstream and central.resi.io hands it
+  back — so nothing is installed at the decoder end. Resi republishes a
+  position only every few seconds and each reading is already stale, so the
+  playhead is estimated between readings rather than repeated; a countdown
+  built straight from Resi's number sits seconds behind and moves in lurches.

+  title bar opens that library — the spots pinned on top, the photos (with a
+  name search) scrolling below — drag a photo onto a slot (mouse, or press and
+  hold on a touchscreen), drag between slots to swap, rename or clear.
+  Dropping a photo onto the person already in a spot makes it *their* photo
+  for that instrument (a nickname like "Rose" for Rosaliz counts): they keep
+  their Planning Center name and spot, and every later Sync uses it whenever
+  they are on that instrument.
+  Planning Center is optional auto-fill on top, not the source of truth:
+  **Sync** reads the upcoming plan's team members and places each one. A
+  person whose Planning Center note names their mic ("Mix 8, VOX 5") goes to
+  that slot — this is how the leader and vocalists, whose position is just
+  "Vocalist", land on the right mic — and everyone else goes to the slot
+  matching their position, one slot per person. Photos come from the library
+  whenever it has one of them, and Planning Center's headshot only when it
+  has none. Someone who plays more than one thing can have a photo per
+  instrument, named `Name - Instrument` (`DJ - Drums.jpg`, `DJ - Vocals.jpg`;
+  Vox/Vocals, Keys/Piano, Drums, Bass, Guitar/Electric/Acoustic, Leader), and
+  a plain `DJ.jpg` for everything else: Sync uses the one for the spot they
+  are in that week. A photo dropped onto someone is remembered for that
+  instrument only. Anything placed or moved by
+  hand for that plan stays put through later syncs; last week's people are
+  replaced.
+  Birthdays in the service week (Wednesday→Tuesday) bring a gold glow and
+  raining confetti, and a Choir button adds the extra spot for the weeks there
+  is one. Admin config: Planning Center credentials, service type and plan, the
+  teams to include, the stage slots (one mic/pack label per line, in stage
+  order), default columns, and the photo folder. Tile settings: parallax,
+  names, mic labels, and birthday confetti with its intensity and a test
+  picker — columns are − / + in the title bar.
+- **Service Times** — every campus's Sunday service times, read from the
+  church website and re-read on a timer, so the board follows the site when
+  the times change through the year. Any service can be marked for
+  production — issue, replay, or do not use — with a note, and a campus
+  taking resi records which of the origin's services it is playing. Marking
+  a broadcast service "do not use" flags every campus riding on it, which is
+  the question the board exists to answer. Marks are shared by every tile
+  and every browser, survive a restart, and expire on their own so last
+  week's never greet a new Sunday. The ＋ picker offers the whole board or a
+  single campus.
+  Admin config is in four groups: **Website** (address, which campuses to
+  follow, refresh interval), **Broadcast** (the campuses the broadcast comes
+  from, and each other campus's resi source), **Manual campuses** (a stopgap
+  for a campus the site has not published yet — the website takes over as
+  soon as it does) and **Marks** (how long a mark lives).
+  Tile settings: campuses, card or list layout, and a **Show** group for the
+  day, role, resi source, campuses fed, notes and the updated line.
+- **Vista Cues** — which Vista 3 cue lists are live, for a booth where
+  nobody runs lighting and ProPresenter and the tracks rig fire Vista's cue
+  lists over network MIDI. Vista sends no feedback of any kind (its OSC only
+  takes commands), so the module listens instead: it joins the senders'
+  network MIDI sessions as one more participant, the way Vista does, hears
+  every note Vista hears, and turns each one into "Go on Walk-in", "Release
+  Worship 1"… from the cue sheet pasted into admin. The tile shows the list
+  fired last, large, with how long ago and who fired it; the other lists
+  still live; the recent notes; and which senders are connected. What it
+  shows is what Vista was *told*: if Vista is closed or someone works the
+  desk by hand, the two can differ, and the title bar's eraser forgets every
+  live list. Plain JavaScript (RTP-MIDI over UDP), no helper; on macOS it
+  advertises itself over Bonjour so it shows up in Audio MIDI Setup's
+  Directory. Admin config: up to three senders (a name, and the host and
+  port of each machine's network session — ProPresenter, the tracks rig,
+  Companion; ProdDash keeps inviting itself in, so each session's "Who may
+  connect to me" must be Anyone, or connect from the sender's Directory
+  instead), the cue sheet (one line per note: `0 = Pre Service`,
+  `61 release Walk-in`, `127 release all`, `30 flash Blinder Flash 1` for a
+  momentary hit, also pause, back, note names, a channel, program changes),
+  middle C naming, whether a Go releases the others, and a folded **This
+  machine** group for the session name, port (UDP 5040 and 5041) and
+  Bonjour. A sheet with no release notes uses groups: a line `[Color]`
+  starts one, a Go in a group replaces that group's live list, and the
+  first group is the tile's headline — so the tile reads "Message" with
+  Color · Blue and House · House Lights Message beside it. A Go in that
+  first group (the main scene) takes over the look and clears the rest, as
+  Vista's last-takes-precedence does; FX fired after it layer on again
+  (the **Main group takes over** switch). Tile settings: other lists,
+  recent, senders, unmapped notes — text size is − / + in the title bar.
 - **Clock** — a big booth clock; also the smallest possible module and the
   reference for module authors.

+# 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.

+   anything that is not JavaScript — ships prebuilt inside the module folder,
+   for Apple silicon macOS and 64-bit Windows; nothing is ever compiled on
+   the machine running ProdDash** (see "Native helpers" below).
 4. **Declare the ProdDash version you need** (`"proddash": ">=1.1.0"` in the
    manifest) and **bump your own `version`** whenever you change the module.
    The admin page refuses to install a module whose requirement the running
    shell doesn't meet, and it offers updates by comparing versions.
 
+### Keeping the interface clean
+
+A dashboard is read across a booth, at a glance, by someone doing three
+other things. These rules are what keep every tile looking like one product
+instead of six. They are as binding as the four above.
+
+5. **No explanatory text in a tile's gear.** No `help` on an
+   `instanceSchema` field or an `instanceGroups` entry. Labels are **three
+   words at most, one or two preferred** — "Slide count", "Item tags",
+   "Running clock". A control that cannot be understood in three words is
+   not a display choice; it belongs in `configSchema`, where `help` is
+   welcome and expected. *One exception:* a `template` field may keep a
+   single `help` line naming its placeholders, which nobody can guess.
+6. **Server-side settings are admin-only.** Anything the module's server
+   acts on — a host, a credential, what to fetch, how often to poll — is
+   `configSchema`. `instanceSchema` is display choices and nothing else:
+   what this tile shows, and how big.
+7. **A tile setting changes that tile and nothing else.** Never another
+   tile, never the module as a whole, never the server. If two tiles must
+   agree on something, it is either admin config or page state the shell
+   owns — not a setting each tile keeps its own copy of.
+8. **Offer toggles for the elements you draw.** Every tile should let the
+   operator switch off the parts it does not need. **One to four toggles:**
+   give them no `group` at all, so they sit unlabelled at the top of the
+   gear. **Five or more:** one group named **Show**, `collapsed: true`,
+   `columns: 2`. Nothing else goes in that group — colours, formats and
+   text belong in groups of their own.
+9. **Title-bar controls are icons.** No `label` on `addButton` or
+   `addMenu`; the tooltip carries the words, and `docs` above covers drawing
+   the icon. A small state indicator may ride alongside an icon — ProdCom's
+   channel button shows a count while a filter is on — but a control is
+   never named in the bar.
+10. **If a control needs words to explain it, it is not a title-bar
+    control.** Put it in the gear. The bar is for actions whose icon and
+    tooltip say everything: refresh, clear, jump to latest, bigger text.
+11. **One control per action.** Whatever has a dedicated title-bar button is
+    not offered again in the gear, and the reverse. Text size is A− / A+ up
+    there, never a "Text size" field; a timestamps button in the bar means
+    no timestamps switch below it.

+
+### 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 });
+```
+
+| Field | Meaning |
+| --- | --- |
+| `channel` | `1`–`6`. Which dashboards flash: each listens to the channels its operator chose in the Layouts menu. 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

+### 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.

+ProdDash $VERSION for Windows (64-bit)
+=======================================
+
+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.

+ * AbleSet — server part.
+ *
+ * Owns the one connection to AbleSet: an OSC subscription over UDP (AbleSet
+ * listens on 39051). `/subscribe auto <port>` makes AbleSet push every value
+ * that changes to our socket, `/getValues` fills in everything that is
+ * already true, and AbleSet's `/heartbeat` every 2 s is how we know it is
+ * still there — when heartbeats stop (AbleSet quit, the Mac slept, the
+ * network dropped) we keep asking again every few seconds until it answers,
+ * because a restarted AbleSet has forgotten its subscribers.
+ *
+ * The raw values become one view-model, streamed to every tile:
+ *
+ *   GET /state          → { state }                     (instant paint)
+ *   GET /stream         → SSE: `state` on any change, `pos` while playing
+ *   GET /timers(/stream) → song and set countdowns for the Timers module
+ *
+ * `pos` carries only what moves every frame (playhead, time left); the
+ * tiles extrapolate between packets from the tempo, so 5 packets a second
+ * draws a smooth playhead.

+/**
+ * Phase lock for whole-second timer reports (the ProPresenter poller).
+ *
+ * ProPresenter reports a running timer as whole seconds — trunc(value):
+ * "12:34" means the true remaining time is anywhere in [754 s, 755 s). The
+ * old poller re-anchored a tile's local count at the bottom of that interval
+ * on every poll, so the displayed digit ran up to a second ahead and then
+ * got yanked back a step whenever a fresh poll happened to sample the next
+ * flip later than the last one did — the poll clock and ProPresenter's
+ * second boundaries drift through each other, so tiles flickered
+ * "…12:33 → 12:34 → 12:33…" about once a second.
+ *
+ * This tracker turns the quantized reports into ONE stable anchor
+ * { valueMs, at } — the continuous value at a fixed instant — which the
+ * client extrapolates from. Rules:
+ *
+ * - The only real information in a poll is a FLIP: the report stepping one
+ *   second in the direction of travel. At the flip instant the true value
+ *   equals the interval boundary just crossed, and the flip happened between
+ *   the last two polls, so their midpoint dates it to within half a poll.
+ * - While a poll's report matches what the anchor predicts (within TOL_MS
+ *   around the reported second's interval), the anchor HOLDS — the same
+ *   numbers are republished, so consumers count along one steady clock
+ *   instead of a freshly re-phased one per sample.
+ * - A report the anchor can't explain re-anchors: at the flip boundary when
+ *   this poll saw a clean one-second flip, else mid-interval (first sight,
+ *   an operator reset/seek, a resume, or clock drift past TOL_MS).
+ * - Before the first flip the anchor sits mid-interval: at most ±½ s off,
+ *   and the first flip (≤1 s away) locks it — instead of the old guaranteed
+ *   whole-second bias one way.
+ *
+ * trunc() semantics also cover overrun: a countdown at −12.4 s reports
+ * "-12", so a negative countdown's interval is (W−1 s, W] and its flip
+ * boundary is W itself, where a positive countdown's are [W, W+1 s) and
+ * W+1 s. Around zero ("00:00:00" covers (−1 s, 1 s)) the flip in from above
+ * crosses +1 s.
+ */
+
+/** How far a report may sit outside the anchor's prediction before it means
+    something real. A flip is dated to the midpoint of two polls, so its own
+    error bound is ±½ poll (~±300 ms at the 500 ms cadence, more when a poll
+    runs long); the tolerance must sit ABOVE that or consecutive flips

+ * nothing upstream: it finds every module whose manifest says
+ * "provides": ["messaging"] (Slack, ProdCom, whatever comes next) through
+ * the shell's /api/modules over loopback, reads each one's destinations
+ * from its GET /messaging, and hands a message to the provider's
+ * POST /messaging/send — so Slack keeps its one Slack connection, ProdCom
+ * its one ProdCom connection, and this module never opens a second one.
+ *
+ * It also owns the PIN. A browser unlocks here and gets a token; every
+ * gated action anywhere — a send through this module, a reaction in a
+ * Slack transcript — carries that token, and the provider checks it with
+ * GET /verify over loopback before touching its upstream. No provider has
+ * a PIN of its own, and no browser on the network can reach a provider's
+ * send route without having entered the PIN here.
+ *
+ *   GET  /state            providers (destinations, identity, status), pin flags, quick emojis
+ *   GET  /stream           SSE `state` events (change-detected, heartbeated)
+ *   POST /unlock           { pin } → { token, expiresAt }     (constant-time, lockout)
+ *                          with the PIN switched off: {} → a token, no questions
+ *   POST /lock             Bearer → forget that token
+ *   GET  /verify           Bearer → { ok, expiresAt }, 401 otherwise — for providers
+ *   GET  /quick            Bearer → preset labels, indexes and bindings (never the text)
+ *   POST /send             Bearer, { provider, destination, text }
+ *   POST /quick            Bearer, { index, provider, destination }
+ *

+ *
+ * Every campus page is built from the same page-builder blocks: a "Times"
+ * heading, the day in bold, then the service times under it, ending before
+ * the "Get Involved" heading. Bounding the slice that way is what keeps the

+ * section, which is why STOP_HEADINGS ends the walk early as well.

+ * an operator puts on a service — out to every tile over SSE. Browsers never
+ * talk to the website.
+ *
+ *   GET  /state      → { state }              (instant paint for new tiles)
+ *   GET  /stream     → SSE, `state` events    (change-detected, heartbeated)
+ *   POST /mark       → mark one service (replay / do not use / issue)
+ *   POST /clear      → drop every mark (a fresh week)
+ *   POST /refresh    → re-read the website now
+ *   GET  /campuses   → { options } — the campuses in play, for the admin
+ *                      broadcast picker and a tile's campus list
+ *   GET  /discovered → { options } — every campus page the website publishes,
+ *                      for the admin "Campuses" picker
+ *
+ * Why the marks live here and not in a tile's settings: a mark is the booth's
+ * shared answer to "is this service usable?", and every campus watching the
+ * board has to see the same one. Per-tile settings are per browser, so they
+ * would let two people disagree about whether the 9:30 is going out. Marks
+ * are written to the ProdDash data directory so a restart mid-morning does
+ * not lose them, and they expire on their own (admin "Marks") so last week's
+ * never greet a new Sunday.
+ *
+ * The website is the source of truth for times. Manual campuses (admin) are a
+ * stopgap for a campus the site has not published yet; the moment the site
+ * carries it, the site's times take over and the admin page says the manual
+ * line can go.

+// spl-capture — calibrated sound-level measurement from a CoreAudio input.
+//
+// Sibling of the Timers module's ltc-capture: same device enumeration, same
+// "stdout is data, stderr is talk" contract, same one-file-no-dependencies
+// rule. The difference is where the work happens. LTC ships raw samples to
+// Node because the decode is cheap and single-channel; sound level is
+// filtering and FFTs over every channel at the device's rate, so the
+// measurement is done here and only the answers cross the pipe.
+//
+// Everything below uses Accelerate, which ships with macOS. No third-party
+// code, no package manager. It ships prebuilt in the module's bin/ (one
+// binary per platform, committed — a booth never builds anything). To
+// rebuild after a change here, on any Mac with the Xcode command line tools:
+//
+//   modules/spl-meter/native/build.sh       (both architectures)
+//
+//   spl-capture --list
+//       every input-capable device: name, input channels, sample rate
+//   spl-capture --device "Dante Via 16 Channel" --channels 1,2 [--cal 0,0]
+//       measures those 1-based channels and writes one JSON line per frame
+//       to stdout, 20×/s. --cal takes one dB offset per channel, in the same
+//       order, from the calibration route (94 dB reference minus what we
+//       measured). With no --cal the numbers are dBFS-relative and the line
+//       says calibrated:false, so nothing downstream can mistake them for
+//       real SPL.
+//
+// Per channel, per frame: the level at EVERY averaging a dashboard might
+// ask for — fast (125 ms), slow (1 s), inf (Leq since reset) and none (this
+// block alone) — plus rolling 1- and 10-minute Leq, C- and Z-weighted peak,
+// raw dBFS and a clip flag. Optionally a 1/48-octave band set for the RTA
+// and spectrogram tiles, only when --bands is passed.
+//
+// Everything is sent every frame on purpose. Two dashboards watching the
+// same room may want different averaging and different banding, and neither
+// choice may disturb the other or restart capture. So the measurement is
+// made once, at the finest resolution anyone asked for, and each tile folds
+// it down to the view it wants. Nothing here is per-viewer state.
+//
+// Weighting filters are IEC 61672 pole/zero prototypes, bilinear-transformed
+// with the top section prewarped, then normalised to exactly 0 dB at 1 kHz.
+// Verified against the standard's table: within 0.15 dB from 31.5 Hz to
+// 4 kHz. The top octave is where the bilinear transform runs out of room —
+// at 48 kHz the 16 kHz point sits about 3 dB low. That is a rounding error
+// on a broadband programme number (A-weighting has already thrown 6.6 dB
+// away up there) but it is a real limit, and the fix if it ever matters is
+// to run the weighting at 96 kHz. `--selftest` prints the table so this
+// claim can be checked rather than believed.
+//
+// macOS asks for microphone permission on first use, and the prompt belongs
+// to whatever launched this — the ProdDash launcher, or Terminal. A server
+// started over SSH gets SILENT ZEROS from every input with no error at all,
+// which shows up downstream as a meter pinned at the floor.
