v2.7.1
422e4ab

Signed sideload build of SpatialFin 2.7.1 (versionCode 102). Supersedes 2.7.0 — install this instead.

Fix vs 2.7.0: the split-A/V freshness gate compared two undisciplined clocks and could silently disable lipsync drift correction during long playback (and permanently after a device clock adjustment). 2.7.0 is withdrawn; use 2.7.1.

What's new in 2.7.x

  • Split-A/V lipsync overhaul — continuous PI speed-trim drift correction, jitter smoothing, θ-disciplined stale-beacon rejection, per-codec audio latency, matched-filter calibration.
  • FCast protocol v4 — NTP clock-sync + commanded synchronized start, fully back-compatible with v3 / non-SpatialFin receivers.
  • Discovery reliability — multiple installs/devices coexist and advertise correctly.

Technical detail: SPLIT_AV_SYNC_V4.md and PR #22.
