No campus's address ships in the repo

prodcom-transcript's endpoint defaulted to 10.3.11.152:24480 — Apollo
Beach's ProdCom. A fresh install anywhere therefore came up reading AB's
comms and reported itself healthy doing it: that is exactly what the new
North Attleboro install did. The default is now blank, so a new install
says "No ProdCom server configured" (in red, as the ProPresenter modules
already do for a missing host) until someone points it at the ProdCom for
that location. Setting a host still connects as before.

The same address is out of SPEC.md's worked example, CLAUDE.md's note
about the reference app, and the prodcom-listener snapshot's config,
README and fallback — that fallback now exits with a line telling the
operator what to set, rather than throwing on an empty URL.

+`boolean` and `switch` are the same true/false value. In a tile's gear popover
+both render as a switch; in the admin page `switch` is the toggle and
+`boolean` the plainer checkbox (use `switch` for a feature on/off that other
+fields depend on). **Label a switch with the noun of what it turns on** —
+"Seconds", "Top bar", "Section headers" — never "Show seconds": on means
+shown or enabled, off means hidden or disabled, and the label shouldn't say
+so twice.
+`color` renders a swatch picker and stores a `#rrggbb` string (give it a hex
+default; the tile applies it as a CSS custom property — see `pco-plan`).
+`multiselect` is several picks from one list — the same `options` /
+`optionsRoute` as `select`, rendered as one switch per option and stored as
+an array of values. A saved value the list no longer offers stays checked and
+marked, so nothing is dropped behind anyone's back. In a tile's gear popover
+it also takes `columns` (2–4) and `allByDefault: true`: a tile that has never
+chosen shows every option on and saves nothing until someone flips one, so
+options that turn up later are on as well (give it no `default` then).
+`select` and `multiselect` may use `optionsRoute` in `instanceSchema` too —
+the popover GETs `/api/modules/<id><optionsRoute>` like the admin page does.
+
+`template` (tile settings) is a text with placeholders, built by dragging or
+clicking the variables the module offers into it: `"variables": [ { "value":
+"{series}", "label": "Series" }, … ]`. Keep `help` to the joining rules; the
+chips carry the names.
+
+`text` is a multi-line string — a `<textarea>` in the admin page, stored with
+its newlines; one item per line is the convention (the `slack` module's quick
+replies). Admin config only.
+
+`group` gathers consecutive fields under a labeled subsection in the admin
+page, so a module with several distinct concerns (e.g. a ProPresenter
+connection and an LTC audio input) reads as clearly separated blocks. Fields
+with no `group` render loose, before/after the grouped ones in schema order.
+
+A manifest-level `configGroups` map can dress a group up further, keyed by
+the group name:
+
+```json
+"configGroups": {
+  "Planning Center credentials": { "collapsed": "whenSet", "help": "Where to get a token…" },
+  "Show / hide":                 { "collapsed": true, "columns": 3 }
+}
+```
+
+- `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`, `toggle`). 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. The popover itself is a small window beside the tile — sized to
+its content, moved by the slim bar on top, closed by clicking anywhere else
+or pressing Escape — so a tile never has to be big enough to hold its own
+settings, and a change can be watched as it lands. Under everything you
+offer, the shell adds **Tile tint** — a colour the operator can wash that
+tile's chrome in, saved with the layout. It is not yours to declare and it
+never remounts you; don't offer one of your own.
+
+A picker entry (see **Presenting multiple tiles**) may carry its own
+`instanceSchema` and `instanceGroups`: tiles added from that entry get those
+instead of the module's. A tile that shows one ProPresenter timer has no use
+for a clock's format switches — give it a schema of what applies.
+
+`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.
+It works the same in a tile's gear (`instanceSchema`): "Short day" and
+"Short month" appear once the clock's "Date" is on.
+
+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

+### 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
+clock, and any module that offers some. A module offers timers by:
+
+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",
+      "label": "Service",
+      "kind": "elapsed",
+      "state": "running",
+      "startedAt": 1757799000000,
+      "elapsedMs": 1000000,
+      "remainingMs": null,
+      "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. |

+ * Title matching for the PCO Plan module — the one answer to "is this
+ * ProPresenter document that Planning Center thing?", used twice:
+ *
+ *   - mapping the document ProPresenter has live to a plan item (the
+ *     highlight and the item runtimes), and
+ *   - recognising the documents an admin picked as the service start / end
+ *     cues (see service-timing.js).
+ *
+ * A ProPresenter name and a Planning Center title rarely agree letter for
+ * letter ("This Is The Day - [ Full ]" vs "This Is The Day"), so both sides
+ * are tidied the way propresenter-core.cleanItemName does (tags in brackets,
+ * leading date codes and dash separators dropped), lower-cased, stripped of
+ * punctuation and compared:
+ *
+ *   1.00  identical after tidying     "Post-Service Loop"  ≈ "Post Service Loop"
+ *   0.85  one contains the other      "Welcome"            ≈ "Welcome & Announcements"
+ *   Dice  2·shared words ÷ all words  "Pre Service Loop"   vs "Post Service Loop" → 0.67
+ *
+ * Filler words ("the", "of", "and"…) are ignored. The thresholds:
+ *
+ *   MATCH_THRESHOLD   0.6   plan items — two of three words is enough, because
+ *                           the item that scores best *and* is next in the
+ *                           plan wins, so a near miss lands on the right row.
+ *   TRIGGER_THRESHOLD 0.75  service cues — a cue starts or freezes the service
+ *                           clock, so one wrong word must not fire it: the
+ *                           pre-service loop (0.67 against "Post Service Loop")
+ *                           stays a non-match, while a renamed
+ *                           "Post-Service Loop", a tagged "Post Service Loop
+ *                           [Full]" (1.0) or a shortened "Post Service" (0.85)

+/**
+ * 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

 /**
  * ProdCom Transcript — server part.
  *
- * One wildcard route that proxies /prodcom/* (including the SSE transcript
- * stream) to the ProdCom API configured in the admin page, so browsers never
- * talk to ProdCom directly (no CORS, and the API key never reaches clients).
- * Ported from prodcom-listener/server.js.
+ * One connection to ProdCom for the whole server, however many dashboards
+ * show the transcript. The module holds the channel list, the groups and
+ * the last entries, follows ProdCom's SSE stream, and hands every browser a
+ * snapshot on connect plus each change as it happens. (It used to proxy each
+ * browser's stream to ProdCom one to one — N screens meant N upstream
+ * connections; ProdCom now sees one.)
+ *
+ * Routes (under /api/modules/prodcom-transcript):
+ *   GET /state   → { status, channels, groups, entries }   (entries by date)
+ *   GET /stream  → SSE: `state` (the snapshot, first), then `entry` for each
+ *                  changed entry, `clear`, and `status` when the link changes
+ *
+ * ProdCom's API, as the reference listener speaks it:
+ *   GET /api/v1/channels, /api/v1/groups, /api/v1/transcript?limit=N and the
+ *   SSE /api/v1/transcript/stream, whose frames carry an entry, or a
+ *   { type, entry | data } wrapper, in a few historical shapes (see
+ *   extractEntries). A bearer API key is sent when one is configured.

+ * Built-in LTC listener — capture child + in-process decode.

+ * Spawns the module's native capture tool (ltc-capture, compiled from
+ * ltc-capture.swift beside it) for the admin-configured audio device, reads
+ * the interleaved s16le stream, extracts the configured channel, and decodes
+ * SMPTE LTC with ltc.js — all inside the module server. Reports upward via
+ * onUpdate roughly 4×/s:
+ *
+ *   { state: 'running'|'stopped'|'nosignal', time, fps, df }   healthy
+ *   { error: '<what is wrong and how to fix it>' }             not capturing
+ *
+ * The capture binary is per-machine (gitignored): if it is missing this
+ * tries one swiftc compile of the source next to it, and otherwise says to
+ * build it on any same-architecture Mac and copy it over. A dead child is
+ * restarted with backoff — fast for a crash, slow for config-shaped
+ * failures (unknown device, ambiguous name) that never fix themselves.
+ *
+ * macOS gotcha this file can't fix: microphone permission. A ProdDash
+ * server launched over SSH or from a bare launchd job gets SILENT ZEROS
+ * from every input (no error!), which shows up here as endless 'nosignal'.
+ * Launch ProdDash from a logged-in GUI context (Start ProdDash.command)
+ * and approve the mic prompt once.

+   (a remounted tile's /state, an avatar) waited in the browser's queue for

+   for the shell's own events. The server opens each module stream for it
+   over loopback (the module's route is untouched and still serves curl and
+   other tools), and forwards every frame with the event name prefixed by
+   its key — `event: slack:/stream|state`. Two frames of its own bracket a
