The player is the unmodified web player in an roHtmlWidget — that already runs
on real hardware. What was missing is everything a page cannot do for itself.
autorun.brs becomes a host rather than a URL wrapper. It owns the widget
lifecycle, because a page-initiated location.reload() does not reliably bring an
roHtmlWidget back: a deploy on 2026-07-28 reloaded every connected player and
the BrightSign was the only one that never returned. The page now posts
{type:"restart"} and the host rebuilds the widget. It also retries load-error
with backoff, falls back to a local page, and runs a heartbeat watchdog that
catches the case load-error never reports — a page that loaded fine and then
wedged on a dead socket or a stalled decoder.
st-bridge.js is the page's half over @brightsign/messageport: registry-backed
identity (localStorage is origin- and quota-bound, the registry is not),
restart-instead-of-reload, heartbeat, and sync-backend reporting. Every method
degrades to a no-op off-platform, so it is safe to load unconditionally.
sync-backend.js decides whose synchronisation a group runs. Ours is
clock-derived and spans any mix of Android, web, Tizen and BrightSign; BrightWall
is frame-accurate and BrightSign-only. auto picks native when every member is a
BrightSign. The refusal that matters: native sync selected for a mixed group
downgrades and says why, because a half-synced group would look perfectly
synchronised on the dashboard while one panel drifted alone.
Dual output via output_mode single|dual|clone — a second widget loads the same
player with &screen=2 so the server can give it its own playlist.
Written against the BrightDeveloper docs; not yet run on hardware. The README
lists what is unimplemented, including the BrightWall runtime API, which that
doc set does not cover.
