+# T1000-E USB priority, 20 October 2026
+
+Source: `ac0daf3cef31a13163d469c1fd538c06708fe05a`.
+
+T1000-E Companions now stop Bluetooth advertising and disconnect the Bluetooth
+client whenever a USB data host is enumerated. This implements the requested
+USB-priority policy after the [simultaneous USB/BLE investigation](companion_qualification_f807_followup_2026-10-19.md)
+did not establish a reliable coexistence fix.
+
+USB priority does not depend on an open serial application or DTR. A charge-only
+supply does not acquire priority. Bluetooth is requested again after the data
+host has been absent for 500 ms, preserving manual-off and wireless controls.
+The policy does not change saved preferences, pairing credentials or identity.
+It applies to the T1000-E Bluetooth and Full Companion recipes.
+
+| Check | Result |
+| --- | --- |
+| Full Companion build, capability markers, runtime RAM and application-only image bounds | PASS |
+| Bluetooth Companion build, capability markers and application-only image bounds | PASS |
+| Priority, startup/wake, manual controls, reply routes, bus-reset hold and timer wrap | Six host tests PASS |
+| Existing Bluetooth preference/CLI and wireless control tests | Eleven host tests PASS |
+| nRF52 BLE regressions, including late connect after disable | 42 tests OK; eight emulator-dependent tests skipped |
+| Contact-stream concurrency | Two host tests PASS |
+| Hosted documentation links | Seven Python tests and JavaScript checks PASS |
+| Install Full on the exact Pi-connected T1000-E | PASS; application only, identity unchanged |
+| USB runtime and saved on/off commands while paused | PASS; status reports `bluetooth off (USB data connected)` |
+| Saved on during USB priority | PASS; command acknowledges saved on while remaining paused |
+| Twenty-second BLE scan with USB enumerated and serial handles closed | Zero target events among 100 scan callbacks |
+| Post-test USB readback | PASS; same identity/version, zero core flags, zero recorded crashes |
+| Physical unplug, BLE recovery and reconnect qualification on this build | Pending user unplug |
+| USB insertion during an established BLE session | Host regression covered; hardware check pending |
+| Charge-only and cold-boot behavior on this build | Host policy covered; hardware checks pending |
+
+The installed version is
+`v1.18.0.1-halo-keymind-cascade-dev-ac0daf3c (Build: 20-Oct-2026)`.
+Its application ZIP SHA-256 is
+`64e09ff2eb8b5e3228f656c7ea99b000c053736b8a020b7eab1429b4d00ab43f`.
+The bootloader and SoftDevice were not changed. All opened USB ports were
+closed, with no framing rejects in the recorded runtime checks. The original
+saved-on Bluetooth choice was restored after the temporary on/off test.
+
+This verifies USB-priority behavior, not simultaneous active USB/BLE, complete
+T1000-E feature qualification or qualification of the other campaign boards.
+Historical battery and wall-power passes belong to their original builds.
