1.1

The Monitor tab, a Minimum logging mode, and keelson 0.6.0-pre.18.

Monitor

A new tab that watches another entity on the bus and draws what it publishes as cards you
choose — value, plot, heading, chart and the rest — the Foxglove panels on a phone. Cards resolve
their inputs by subject, so one board follows whichever source is publishing.

It reads the router's REST plugin as Server-Sent Events rather than subscribing, because a
subscribed sample aborts this Zenoh binding; docs/monitor.md explains the
mechanism. The Zenoh subscriber is written and ships dormant behind
ZenohBinding.SUBSCRIPTIONS_SAFE: it has been proven on a phone against a patched binding, and a
fix is proposed upstream (milyin/prebindgen#758, eclipse-zenoh/zenoh-flat-jni#49). Watching another
boat never restarts a run.

Minimum logging

A mode for a phone carried only to mark events: eight channels instead of thirty-nine, position
capped at 0.2 Hz, IMU and media off. Measured over two hours on a Pixel 6 — 0.361 MB/h against
240.2 MB/h, and about 25 hours of battery against 11. It narrows the tuned profile rather than
editing it, so Full comes back untouched.

Subjects and protocol

Re-synced to keelson 0.6.0-pre.18: all nineteen vendored protobuf files byte-identical, QoS
profiles re-verified. Six host-telemetry subjects adopted — free and used disk, memory, swap, host
name and boot time — with the disk ones carrying their mountpoint in the source id.
cpu_load_pct and cpu_temperature_celsius are unobtainable under an app's own uid and are
documented as such. set_config now refuses with UNSUPPORTED, which pre.18 added for exactly
this case.

Fixes

• A held radio reading's timestamp is converted once per reading, not per poll: ~166 real
  measurements had been publishing as 18 766 distinct instants.
• The MCAP schema descriptor is generated into build/ instead of src/, which had made
  ./gradlew build refuse to run at all.
• CI stopped installing an SDK package Google withdrew.

Docs

An install and setup guide, a Monitor page, and deploying.md narrowed to one audience.
