Simplify LTC to its one working source — the built-in audio listener — and
make the admin UI reflect it.
Module:
- Remove the stage-display websocket source (stage-ws.js, stagePassword)
and the /v1/timecode/status API probe — both dead on ProPresenter 21.4.
- Remove the remote-reader ingest (POST /ltc, ingestToken, tools/
ltc-reader.js): the module owns LTC end to end now. The decoder selftest
moves to modules/propresenter-timers/ltc.selftest.js so the engine stays
covered.
- composeLtc collapses to the listener: running/stopped/nosignal, or a
clear note when disabled / no device / capture failed / starting.
- Manifest: ltcEnabled is now a `switch`; ltcDevice and ltcChannel carry
showWhen:"ltcEnabled"; ProPresenter and LTC fields carry `group` labels.
Shell (admin) — backward-compatible additions, coordinate with the shell lane:
- New `switch` field type (boolean shown as the enable-toggle control).
- `group`: consecutive fields render under a labeled subsection.
- `showWhen: "<key>"`: a field is shown only while that boolean/switch is
on (and actually collapses — .field[hidden] override, since .field's
display:flex outranks the [hidden] UA default).
- applyConfigPatch coerces `switch` as boolean. Documented in MODULE-GUIDE.
Verified: engine selftest (29 checks); listener decodes BlackHole loopback
(running 30fps, ageMs); device picker lists inputs; POST /ltc now 404s;
admin shows two labeled groups, the switch, and device/channel appearing
only when the switch is on (computed display none↔flex confirmed).

The LTC card repainted only on server anchors (~4x/s), so the frame
counter jumped in ~7-frame steps. Now the client counts every frame
locally between anchors and re-syncs on each one — frame-accurate and
smooth, with no extra network traffic.
- Server anchors carry ageMs (how old the decoded timecode is) so clients
can pin the anchor to their own clock. ltc-listener reports it while
running; composeLtc passes it through (listener) or derives it (reader).
- Client does exact SMPTE frame<->timecode math (parseTc/tcToFrames/
framesToTc, incl. 29.97 drop-frame minute counting) and advances the
display in a requestAnimationFrame loop at the LTC's own rate.
- Robust when rAF is throttled (backgrounded tab): render() paints the
extrapolated frame at the 4x/s anchor rate too, so the display never
freezes — the rAF loop only refines it to every frame when visible.
- Anchor jitter can't tick the counter backwards (small regressions
clamped; genuine seeks/re-strikes pass); freshness cap stops freewheel
into phantom frames when anchors stop arriving.
Verified: SMPTE math against the encoder over 200k drop-frame frames plus
round-trips; the extrapolation pipeline simulated at 30/25/29.97DF showing
strict +1-per-frame advance and correct DF boundary crossing.

Adopts the new contract: the manifest declares "proddash": ">=1.2.0"
(this module's admin device picker needs the optionsRoute select support
this branch adds), module version 1.2.0, and the shell version bumps
1.1.0 → 1.2.0 for that admin capability. The optionsRoute paragraph
merged into the guide's new schema section cleanly.

ProdDash now has a version (package.json, 1.1.0) and modules declare the
shell versions they need ("proddash": ">=1.1.0" in the manifest). A module
whose requirement this shell doesn't meet is listed in the admin page but
never loaded, and cannot be installed from the catalog.
Modules come from two places: bundled with the checkout (modules/) and
installed from the admin page into the data directory (<data dir>/modules/).
Same id in both → the newer version runs; a downloaded copy the bundled one
has overtaken is removed. The admin page's new "Available modules" section
lists modules in the ProdDash repo that aren't installed here — one small
tar.gz of the branch is fetched (at most every few minutes, only while the
admin page is open or for the periodic update check) and read with a
dependency-free tar reader (ustar, GNU long names, pax headers; the pax
global comment carries the commit sha). Install downloads the module folder
into the data directory and mounts it immediately; a module card offers
"Update to vX" when the repo has a newer version. Uninstall removes an
installed module's files; a bundled module is hidden instead (its folder
belongs to the app) and can be restored from Available modules without a
download. Settings are kept across uninstall/reinstall.
Shell updates: the server compares the repo's package.json version and
commit sha with its own (git rev-parse when the app folder is a checkout),
shows a banner in the admin page, and "Update now" brings the app folder up
to date — git pull --ff-only for a checkout that is on the repo branch with
no local changes (file modes ignored), otherwise the archive is unpacked over
the folder (runtime state and .git untouched). The server then exits with
code 75 and starts its own replacement unless PRODDASH_LAUNCHER is set; the
replacement waits for the port to free up (EADDRINUSE retry). The page polls
until the new version answers. PRODDASH_REPO (owner/repo#branch),
PRODDASH_ARCHIVE_BASE and PRODDASH_NO_REMOTE_CHECK configure/disable it.
Docs: MODULE-GUIDE gets the rules every module follows (all settings in the
admin page, dependencies shipped inside the module, everything runs inside
the module's server entry — no helper programs, declare the ProdDash
requirement and bump the version), the proddash/version manifest fields and
the new installation story; README gets "Installing modules and updating";
CLAUDE.md summarises the rules.

The LTC listener now lives inside the module: it spawns the native
ltc-capture helper (moved into the module folder, compiled on first use,
exact-name device matching) for the admin-selected input device, extracts
the configured channel, and decodes SMPTE LTC in-process (ltc.js — the
engine, shared with tools/ltc-reader.js, which remains the remote-machine
option posting to /ltc).
Admin config: an "LTC listener" switch, an audio-device select populated
live from the new GET /ltc/devices route, and a 1-based channel number.
The switch off means LTC is gone entirely: no LTC entry in the Add-tile
picker, no LTC row in the Timers menu or All-timers grid, no stage/API
probes, and POST /ltc answers 409. Source precedence with it on:
listener-with-data, fresh remote reader, listener's own no-signal verdict,
then the legacy API/stage chain.
Shell (admin page): `select` fields learn `optionsRoute` — options fetched
from a module route at render, saved value kept selectable when the route
or device is gone. Documented in MODULE-GUIDE; backward compatible.
Coordinate with the shell lane before its next admin.js change.

ProPresenter 21.4 exposes no timecode through any API, so read the LTC
where it actually lives — the audio feed:
- tools/ltc-reader.js: zero-dependency SMPTE LTC decoder (biphase-mark,
adaptive bit clock, envelope-scaled comparator) fed s16le PCM on stdin
from ffmpeg/sox; POSTs running/stopped/nosignal + timecode + frame rate
(incl. 29.97 drop-frame) to the module. --selftest runs an encoder→
decoder suite (24/25/30 fps, DF minute counting, low level + noise + DC,
dropout recovery); --demo synthesizes live LTC through the real decoder
and ingest path with no audio hardware.
- Module: POST /ltc ingest route (optional bearer token, validated body,
6 s staleness with automatic fallback to the API probe / stage source),
richer LTC state (status, fps, df, reader source), health messages.
- Client: LTC card shows Running · <rate> / Stopped (held frame) /
No signal; works LTC-only with no ProPresenter host configured; the
reader-fed card no longer grays out when only ProPresenter is down.

Verified against ProPresenter 21.4: the legacy stage-display protocol
(ptl 610 — the only version PP21 accepts; newer values get 'out of
date') omits stage objects it predates, so a timecode field labeled LTC
never appears in any layout's frame list, and no timecode messages were
observed while idle. Fallback: an unknown uid streaming timecode-shaped
text (a fourth :FF group; not any configured timer's uuid) is bound as
LTC after two advancing samples, and that binding survives layout
refreshes. pp-timers-mock gains --ltc-unlisted to exercise the path.

ProPresenter's HTTP API has no timecode route (verified: 21.4 returns
404), but its classic stage-display websocket still answers — so LTC now
comes from a stage layout field labeled "LTC": a zero-dependency RFC6455
client (stage-ws.js) authenticates (new stagePassword admin config),
resolves the LTC-labeled frame's uid from the layout list, and treats any
message carrying that uid as the timecode text. "Receiving" is a 2.5s
staleness heuristic; frozen or placeholder text reads as no-signal. The
HTTP probe stays authoritative when it ever answers (a 404 verdict is
retried once a minute), and the LTC card surfaces the reason when
timecode is unavailable (bad stage password, no LTC field). pp-timers-mock
grows a /stagedisplay websocket with --stage-pwd and --no-ltc-field to
exercise every path.

Title bars (tiles and the main menubar, which gains the same notch tab)
now collapse and reopen with a height animation instead of popping. The
menubar's hidden state persists per browser. ProdCom timestamps move
inline to the right of the channel name, keeping their text style; the
clock button toggles just their visibility. New fullscreen button (left
of ＋): entering fullscreen auto-hides the menubar and auto-fits the
layout — occupied columns stretch proportionally across the width, tiles
whose bottom edge lands within two rows of the viewport bottom stretch
to end exactly at it, small tiles (h ≤ 2) alone in their columns are
exempt, and scrolling is disabled when nothing extends below the fold
(deeper layouts keep natural rows and scrolling). All fullscreen fitting
is visual-only and reverts on exit; editing affordances are parked while
in it. Corner resize indicators now appear only on tile hover, and a
second resize handle on the bottom-left corner resizes from that edge.

New configSchema type 'endpoint' declared in the module spec: anything
that points at a device or service on the network must be one endpoint
field, rendered identically for every module in /admin as a joined
Host/IP : Port control and stored/handed to the module server as
{ host, port }. Migrates all three connection modules — ProdCom (was a
full URL field), ProPresenter and Timers (were separate host + port
fields). Legacy stored configs (prodcomUrl / flat host+port) keep
working until the admin form is re-saved, at which point the new shape
replaces them. MODULE-GUIDE documents the type and the presentation
rule: no split host/port fields, and full URLs only for genuine web
addresses.

Adopt main's new multi-tile contract: the module's server exports
tiles() (answered from the poller's held state, never a fresh upstream
request) listing All timers, one entry per discovered timer, and LTC
timecode. The client branches on moduleApi.variant — solo tiles render
exactly one card with no selection menu, and a solo timer that vanishes
from ProPresenter shows a labeled "Not in ProPresenter" card instead of
erroring (visible even in the compact layout). pp-timers-mock gains
--drop=<uuid,...> to simulate a timer deleted in ProPresenter.

New propresenter-timers module: polls /v1/timers + /v1/timers/current
(shapes verified against openapi.propresenter.com), probes the
undocumented /v1/timecode/status for LTC and honestly reports
"not available on this ProPresenter" when absent. Per-tile timer/LTC
selection via a Timers ▾ header menu (never-seen timers default on),
responsive auto-sized cards with state-derived colors (the API exposes
no per-timer color), unmistakable overrun. Includes tools/pp-timers-mock.js
for developing without a real ProPresenter.

Topbar: the add button is now just ＋ and the layout button a 3-segment
grid icon (two squares + one tall rectangle). Modules no longer build
their own toolbars — moduleApi.header.addButton/addMenu put controls in
the tile's title bar next to the gear/close (menus are fixed-positioned
by the shell so a tile's overflow can't clip them, and everything a
module adds is removed automatically on unmount). Each title bar grows a
notch on its bottom edge that hides/shows the bar, ProdCom-Listener
style; the choice persists with the layout. Modules renamed: ProdCom and
ProPresenter. The ProdCom tile regains the original listener tools as
icon buttons in its title bar: timestamps toggle (clock), A−/A+ text
size, jump-to-latest, and a circle-with-cross clear button, plus the
Channels menu. MODULE-GUIDE documents the header API; README updated.

Milestone 4. propresenter-core copied in unchanged (single home for every
ProPresenter 7/20 quirk). Server part owns the one polling connection and
exposes GET /state plus GET /stream (SSE, change-detected, heartbeated);
health reported for the admin page. Client ports the wall display's
rendering: fill-the-box title fit that never breaks words, tidied titles,
slide meta + progress bar, NEXT list with hidden-row '+ N more' overflow,
playlist name and live chip, all scaled to the tile via a JS-set --unit.
Verified against pp-mock.js including the arrangement-repeat case (the
counter follows core's honest-live-index rule, never X > Y) and
kill-and-restart recovery.

Milestone 3. Server part proxies /prodcom/* (SSE passthrough included) to
the admin-configured ProdCom URL, adding the Bearer key server-side so it
never reaches browsers; reports proxy health for the admin page. Client
ports the prodcom-listener UI into the module contract: history load,
live SSE with in-place updates of in-progress speech, channel colors,
channel visibility toggles + group presets (persisted per tile), hard
channel filter / text size / timestamps as instance settings, auto-scroll
with a jump-to-latest pill. tools/prodcom-mock.js simulates ProdCom
(word-by-word in-progress speech) for testing; verified against it,
including kill-and-restart recovery.

Milestone 2. Server scans modules/*/module.json, serves module assets at
/modules/<id>/, mounts optional server routes (exact + trailing-/* prefix
patterns) under /api/modules/<id>/ with per-module config from
config/modules.json, and lists enabled manifests at GET /api/modules.
Shell dynamically imports each module's client.js and hands it the
moduleApi (config, instanceSettings, scoped fetch, auto-reconnecting sse,
setStatus). Clock module proves the contract end to end; password-typed
config fields never leave the server.
