The controller · bad India
The controller halves its rate
on every lost packet.
On a long link, that starves video.
A controller that watches delay.
One lost packet is noise.
Run the matrix.
Every link, two minutes a cell.
Bad India: 10% → 32% of frames.
Same region: still 100%.
Logs: jitter mistaken for a queue,
up to 24 slowdowns in a run.
Three revisions later: zero.
