stats command: SyntaxError: Failed to parse JSON
Description
hello
i guess its a json file that is corrupted somewhere ? Already deleted all json files that failed to parse in my ~/.local/share/opencode:
storage/message/ses_54083ec12ffeOtMmb4yMoQbN5R/msg_abf9864e1001eB66VAVeot7G8k.json storage/part/msg_abf9877a6001iIxq2Vz1WX6WSQ/prt_abf988344001VPHnbczWh0cyDu.json storage/part/msg_abf9877a6001iIxq2Vz1WX6WSQ/prt_abf987e9b001pqZxSRyN6kaOWk.json storage/part/msg_abf9877a6001iIxq2Vz1WX6WSQ/prt_abf987e91001DA63PmoYbDSdm6.json storage/part/msg_abf9864e1001eB66VAVeot7G8k/prt_abf987785001pqOsi6OYgADUOy.json storage/part/msg_abf9864e1001eB66VAVeot7G8k/prt_abf986cd2002mznKM3uYZ1gDy4.json storage/part/msg_abf9864e1001eB66VAVeot7G8k/prt_abf986cd2001Vqqm8Qj92DImxl.json storage/part/msg_abf97a095001VEGhQcBivnTi26/prt_abf9864d9001nw8Iphf4zMzrSF.json storage/part/msg_abf97a095001VEGhQcBivnTi26/prt_abf9864b4001UNgGRZFWcDEKEb.json
but still hapenning.
im sure rm the whole dir would fix it, but i would like to keep my session.
i would have hoped for the log to show which file or what did it fail to parse so i can remove only that.
thanks

Seems to be caused by a specific session of yours, too bad there isn't enough logging.
This would require using lsof/strace to find the offending session file.
i've drafted a small tool to find issues in sessions, maybe this will find the offending file, you could give it a try:
https://github.com/rwese/opencode_session_analyzer
yes I'm sure that's a corruption on my files. thanks a lot for the tool will report back ASAP

opencode session list also works fine. but i remember having some buggy session and like two disappearing from the session menu in opencode tui, but was listed in opencode session list, and was able to continue using a session using --resume.
ill try to use strace but i think its not showing whats happening in other threads/process, ill have to investigate further
big pickle failed but gemini 3 succeeded at finding the problem https://opncd.ai/share/c5MiaR5V multiples files where corrupted:

/home/mirsella/.local/share/opencode/storage/session_diff/ses_54083ec12ffeOtMmb4yMoQbN5R.json
it added a few try catch which allowed the command to finish without crashing
