P3 decode science: every AU is stamped as its last piece enters the codec, so
the decode stage splits into feed (received→queued: hand-off + input-slot wait)
and codec (queued→decoded: the decoder alone — a slice head start would show
here). The split + an always-on capture→decoded e2e ride the 1 Hz pf-present
line, so a wireless HUD-off A/B reads everything from logcat; the HUD equation
gains the split (indices 30/31), the skipped counter tells benign newest-wins
pacing from parked-AU overflow (32), and a −2-refresh Apple-HUD-equivalent twin
makes iPhone comparisons honest (Apple shaves its OS floor; Android shows raw).
Connect now logs the per-mime decoder picks + FEATURE_PartialFrame verdicts
(tag pf.caps) — on the NP3 all three c2.qti low-latency decoders say no, so
parts delivery never arms and P2d is inert there; a debug.punktfunk.force_parts
sysprop overrides the probe for the on-glass question the API cannot answer.
Forced on glass: c2.qti accepts PARTIAL_FRAME pieces without erroring but only
assembles them — codec time unchanged, so the overlap is dead on SM8735 either
way.
