Honor the packet length declared at byte 1 so embedded 0xFF and 0xFE payload bytes do not restart or truncate valid frames. Preserve partial packet state across serial-read timeouts and validate the declared length and final marker before dispatch. Add the compatibility initialization request, model description override, protocol metadata and per-model bypass alarm behavior. Correct the published input voltage extrema and document the changes.

Initialize protocol and bypass metadata explicitly for every known model so Clang's missing-field check remains clean. Add a documented defensive default to the initialization selector and teach the documentation spell checker the hexadecimal xFE token. Signed-off-by: Lucas Bocchi <lucas.bocchi@gmail.com>
Check the HWINFO checksum in its interpreter and publish the documented lower-case battery charger states. Log already-known HWINFO packets quietly and expose rejected frames through raw packet debugging. Credit the packet captures and follow-up analysis contributed in issue networkupstools#3592 directly beside the affected code and in the release notes.

Pass the packet data, byte count and serial descriptor directly to the helper. Keep serial validation, reopening, write checks and diagnostics inside the helper so the initialization calls are easier to read. Signed-off-by: Lucas Bocchi <lucas.bocchi@gmail.com>
