Add a standalone Pico2W image reusing the configured nonconnectable wake burst without Bluepad32, controller-host profiles, Classic/LE-central roles, connection pools, pairing or writable TLV storage. Explicitly disable and verify Classic inquiry/page scan before declaring readiness. Keep the original controller firmware and captured wake identity unchanged. Expose bounded SPWB1 CDC commands with exactly-once request IDs, explicit failures and radio progress independent of serial backpressure. Add the cross-platform switch-pico-wake script with strict preflight, bounded I/O, no automatic rebroadcast, status-only mode and preserved uncertain-outcome metadata. Standard USB serial requires no WinUSB/Zadig binding. Add isolated --wake-only build/publication selection and document setup, backup and physical-BOOTSEL recovery. Validate776 tests, focused framing and lifecycle cases, ELF isolation and actual CDC operation on only the new board. One burst completed in2.095s; malformed/status/reconnect input and same-ID replay caused no additional broadcast. Original Pico untouched. Private firmware images, console configuration and backups are excluded.
