// Downstream video chaos contracts.

//
|
|
// Scope: source-stall, decoder-stall, and dropped-frame behavior without
|
|
// requiring capture cards or opening UI windows.
|
|
// Targets: server eye capture, server stream core, and client monitor pipelines.
|
|
// Why: when downstream video gets rough, it should drop or report stale frames
|
|
// rather than hiding backlog, wedging the stream, or silently showing black.
