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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
