A broadcast rail that tells the truth: LIVE vs REPLAY in Rive

The instrument rail from my FLAGFALL broadcast package: a status strip that distinguishes a live feed from a replay honestly, beats a dot when a real frame lands, and degrades through a designed failure ladder when the feed stalls, instead of freezing and pretending.

Roughly 245 bound properties are written into the file per frame from the runtime. The bare .riv is deliberately static, because the motion IS the data: adapter stamp, feed-beat dot, connection states and the failure ladder are all driven by JavaScript through Rive data binding.

This is the unglamorous half of broadcast graphics, and the half that decides whether viewers trust the screen.

Part of the FLAGFALL build, published separately because it is a distinct deliverable: the honesty instrumentation that sits under the show graphics.
