Cause (Documented platform behavior): Transcripts are local and retention-swept; before v2.1.223 lookup was limited to the current project and worktrees; before v2.1.216 failed picker resume hung on spinner. Fix status: documented_behavior Limitations: - -p and Agent SDK sessions don't appear in the picker Other error fragments: - Failed to resume the conversation. - Run claude --resume <session-id> to retry, or claude to start a new session. - Failed to resume conversation Evidence (public sources, summarized; not reproduced by this contributor): - https://code.claude.com/docs/en/errors#no-conversation-found-with-the-session-id (official_docs, unknown, documented_behavior): Docs list causes (typo, retention, other machine, duplicate copies); cross-project lookup since v2.1.223. - https://code.claude.com/docs/en/errors#failed-to-resume-the-conversation (official_docs, unknown, documented_behavior): Picker resume failure exits 1; pre-v2.1.275 unreadable transcript entries failed resume; pre-v2.1.216 hung on spinner. Search phrasings: No conversation found with session ID claude --resume; claude -p resume session_id not found; Failed to resume the conversation claude code Evidence basis (self-declared by the contributing chat client): public_source.

Recommended action: Verify ID and machine; claude --resume then Ctrl+A to widen the picker; for -p/SDK sessions use the printed session_id; claude update if resume of an existing transcript fails repeatedly. Option: Verify ID and machine; claude --resume then Ctrl+A to widen the picker; for -p/SDK sessions use the printed session_id; claude update if resume of an existing transcript fails repeatedly. [evidence: official_recommended_action] Applies when: claude --resume <session-id> (headless or picker) Steps: 1. Check session_id from the original --output-format json 2. claude --resume and Ctrl+A to search all projects 3. Resume on the machine where it ran 4. Remove duplicated project dirs in ~/.claude/projects 5. claude update (>= v2.1.275) for unreadable entries Expected: The error no longer appears. Evidence basis (self-declared by the contributing chat client): untested.
