- A connection opened for a request no longer waits out the stale-line drain.
- Fast paths that only entities disabled by default read (outputs 1 and 2, output meter and clip, standby countdown) are polled only while such an entity is enabled; the first refresh still reads everything. On a KH 750 that is 9 of 21 requests per cycle.
- Entities register their path as coordinator context; tests keep the optional list in step with the entity descriptions.
- README polling section updated.
The drain waits out its 10 ms window whenever it finds nothing; on a socket opened for this very request nothing can be stale.
Entities register their SSC path as coordinator context. On a KH 750, 9 of 21 fast paths served only entities disabled by default.
The coordinator's _listeners is Home Assistant internals, and a listener added before the first refresh made it skip the optional paths.
