Problem

The Claude Code session transcripts for this project go back only one month. The transcripts are the only record of the user's verbatim pushback on proposed approaches. That pushback is the source data for the challenge-moves work in docs/research/challenge-moves/. Each day without a change can lose one more day of episodes.

Observed

A transcript extraction on 2026-10-02 found 142 top-level session files in ~/.claude/projects/-home-jared-dev-cc-os/. The files are dated 2026-09-03 to 2026-10-02. Older transcripts are not there.

The likely cause is the Claude Code transcript cleanup. The setting cleanupPeriodDays in settings.json controls it, and the default is about 30 days. This cause is not verified on this machine.

Reproduce

n/a: this is a retention and backup task, not a defect in this repository.

Approach

Not decided. The user named two options and accepts one or both:

Extend the transcript retention period.
Back up the transcripts to the user's network drive. The user dictated "psychology Drive"; this is probably the Synology drive. Confirm the destination with the user.

First step: verify the cause of the missing transcripts.

Origin

Trigger: a script that extracted the user's messages from the session transcripts for the challenge-moves pilot, 2026-10-02.
Improvised this session: copied the extracted episode files to docs/research/challenge-moves/ so that a reboot does not delete them.
Chain: transcripts older than one month are missing ← Claude Code transcript cleanup (not verified) ← UPSTREAM-TOOL (Claude Code, version not recorded).
Root candidate: this ticket.
Where: ~/.claude/settings.json and ~/.claude/projects/-home-jared-dev-cc-os/
