USB power; no microSD card; uncontrolled ambient Wi-Fi/BLE.
Heap values are bytes of byte-addressable internal RAM.
Stack order: UI / radio / BLE / storage. Values are free stack watermarks in bytes.
Health snapshots start near 5 s uptime and repeat every 30 s.
Queue drops are reported; this is not a controlled capture-loss or release-acceptance test.
The two pre-Tag-Watch captures reported the expected missing-card initialization error 0x107.
Observed identifiers and packet payloads are deliberately omitted.
