The buffer / on-GPU / downloader counts flip many times a second, so a 3s
status poll only ever samples noise — the tiles looked frozen (same value
twice) or random (wildly different), reading as "the Status section doesn't
update" when the backend was in fact live (operator-flagged 2026-07-01).
Replace the three instantaneous gauge tiles with two derived RATE tiles:
- jobs / min — GPU throughput, from the monotonic `processed` counter
- downloads / min — fetch throughput, from a new monotonic `downloaded`
counter (bumped when a job is decoded into the buffer)
Together they also show pipeline balance (dl/min > j/min ⇒ GPU-bound; the
reverse ⇒ GPU starved). Both are EWMA-smoothed over the poll deltas, clamped
at 0 (agent restart resets the counters), and skip a backgrounded-tab gap.
The still-useful instantaneous state is demoted, not lost: buffer stays as
the occupancy bar; downloaders/consumers/on-GPU move to the sub-line. `waited
out` (transient) gets promoted to a tile.
backend: worker.status() gains `downloaded`; `_bump(downloaded=)`.
frontend: retiled Status + rate math in applyStatus; VERSION → .7.
