User-directed changes:
- steady no longer pins the converged level: the endpoint is shared,
other tenants move its capacity mid-run, so steady keeps judging
forever (+1 when rate beats reference by 5%, -1 when 15% below,
reference drifts by EWMA). Large drops are still handled by the
failure channel's multiplicative x0.7; the +-1 path tracks drift.
- dwell fallback scales with the OBSERVED completion cadence:
max(120s, 3x inter-completion gap EMA). A 25s timer judged 60s-per-
request benches on one lone sample.
- MIN_OK floor raised to 5 (evidence = max(5, 2x level)).
Simulated capacity drift 8->3->8: gate follows down then recovers.
