The daemon now requests the Bluetooth headset profile itself (pactl
set-card-profile) the moment a take starts, instead of waiting for
WirePlumber to notice the stream and run its switch timer. The microphone
link comes up 0.15-0.18 s after the key instead of 0.21-0.27 s; WirePlumber
still restores A2DP when the stream goes away. First real audio is now at
0.82-0.86 s, which is the headset's own floor.
When the plugin is updated while the daemon runs, the daemon sees its source
change, exits with code 4 once idle, and the shell service relaunches it
without counting that as a crash.

The bar turned green after 2 s on a timer even when the microphone delivered
nothing. It now turns green only on real audio: RMS above 0.0005, or three
consecutive chunks that are not digital silence (the virtual mic emits one
stray nonzero chunk right after start, and a Bluetooth headset's floor ramps
in from a few LSB). Measured 1.2-1.4 s after the key, within 0.14 s of the
first real samples.
diagnostics/bluetooth/ records how startup went from ~1.6 s (or never) to
~1.1-1.4 s: a btusb driver bug, two PipeWire bluez5 bugs, a 500 ms WirePlumber
switch timeout and an over-broad auto-connect rule. Those fixes are machine
level and live outside this repo; the patches, tools and measurements are here.
STARTUP-TIME.md is the summary and explains the ~0.9 s hardware floor.
