The six-microphone path is separate from the bridge. Scarlett speaker loopback
is the current timing authority when calibration chirplets are playing.
`MimirChirpletTimeline` owns the birdsong-like timeline fingerprint: a
deterministic unbounded chirplet stream where event `N` is generated from `N`,
with no repeat cycle or remembered random state. Mimir continuously queues that
timeline through Aquarium audio, compares mic buffers against loopback by
chirplet-energy delay estimation, and can build a provisional aligned mono
frame for channels that clear the confidence gate.
`MimirChirpletTimeline` owns the birdsong-like timeline fingerprint: an order-3
de Bruijn sequence over 32 separated chirp symbols. Any three consecutive
correctly detected symbols identify the event index inside the current operating
horizon. Mimir continuously queues that timeline through Aquarium audio, uses
coarse chirplet energy for acquisition, refines delay from matched event
indices when the symbol decoder succeeds, and can build a provisional aligned
mono frame for channels that clear the confidence gate.
Reports now carry fractional delay and per-band matched energy. The hub also
owns smoothed per-source sync state with delay-slope/SRO in ppm. `MimirRuntime`
runs the analysis online and can print live telemetry with
