Fox 2026-06-05: "both and see if we could lower to 1.3 secs as floor
for listeners on the high quality stream."
Two additions to the Double Dragon controller:
1. Predictive GROW (lead, not lag).
The existing 5s-tick path watches loss/jitter — strictly a lagging
indicator. We now ALSO watch the worklet's bufferedSeconds
reports (every ~683ms) for rapid drain. If the buffer drops by more
than 25% of its current target over a 1.5s window, GROW
immediately — don't wait for loss to appear in the next 5s
sample. Catches wiggle ~2s after it starts vs 5-10s on the
lagging path.
2. Self-calibrating floor.
Each publisher tracks its own maxWiggleDurationSec for the
session. Floor for SHRINK is max(role-base, maxWiggle × 1.5). A
stable publisher's listener can shrink to 1.3s. After observing a
1s wiggle the floor lifts to 1.5s; after a 4s wiggle, 6s (clamped
to MAX). Resets when user leaves + rejoins.
Constants:
- DD_BASE_LISTENER_TARGET_SEC = 1.3 (was 2.0)
- DD_WIGGLE_FLOOR_MULTIPLIER = 1.5
- DD_DRAIN_THRESH_FRAC = 0.25
- DD_DRAIN_WINDOW_SEC = 1.5
Telemetry log lines:
- "double-dragon pub=XXXX PREDICTIVE GROW → 4s (buf drained Nms in N.Ns)"
- "double-dragon pub=XXXX wiggle ended dur=N.Ns — floor now N.Ns"
- "double-dragon pub=XXXX SHRINK target → N.Ns (clean N samples, role=X, max-wiggle=N.Ns)"
This is the "lead + lag, AND self-tuned floor" loop. The 1.3s listener
floor only applies to clean-history sessions. A wiggle-prone publisher
will see the floor stay elevated automatically.
