Unreleased

• Bridge log files are no longer empty by default. The tracing filter directive matched a crate-name prefix that the binary's actual crate identifier did not satisfy, so every info! / warn! / error! call dropped silently on both stderr and the rotating file. couchlink run is no longer a silent console window; bundles now carry readable bridge logs.
• couchlink bundle can now pull the firmware's diag-log ring over UDP from a running Pico. The bundle tries setup-mode USB-CDC first and falls back to a unicast UDP probe against the last-known address. pico-diag.txt and the manifest now name which source produced the log (setup-cdc or run-udp).
• When CDC capture fails, pico-diag.txt now names the specific step that broke -- port enumeration, port open, HELLO write, HELLO read, or frame decode -- with bytes-received count and a hex dump of any pre-magic bytes seen on the wire. The previous stub said "couldn't capture, see the bridge log" without distinguishing which path failed.
• couchlink flash refuses to write a UF2 whose family ID does not match the detected BOOTSEL drive. The previous behavior was a warning that continued the copy, which produced a Pico that silently never re-enumerated when an RP2040 image was dropped onto an RP2350 (or vice versa).
• couchlink setup stage 4 waits up to 120 s (was 60 s) for the setup-mode CDC port to appear and prints a progress line every 10 s while it waits. The previous 60 s budget was tight when the host went through USB passthrough (VM, WSL2) or a first-time driver bind.
• couchlink setup stage 4 treats a port-disappeared event right after REBOOT_TO_RUN as success rather than a hard error. The firmware always reboots after handling that command, so a missing reply is the expected outcome of a fast reboot, not a failure.
• Firmware CDC bcdDevice is derived from the firmware semver macros (PICO_BRIDGE_FW_MAJOR/MINOR) so Windows re-binds usbser.sys after a CDC-protocol break instead of reusing a cached binding from an older interface layout.
• Release zip now stages setup.ps1, couchlink.exe, and couchlink-pico.uf2 together.
• Wiki pages now hold setup, flashing, troubleshooting, build, and protocol notes.
