Session Discovery

Search every supported harness even when the current conversation is running in only one of them.

Transcript locations

• Claude Code
  • Project transcripts: ~/.claude/projects/**/*.jsonl
  • Prompt index: ~/.claude/history.jsonl
  • Delegated work: nested <parent-session-id>/subagents/*.jsonl
• Codex
  • Active transcripts: ~/.codex/sessions/**/*.jsonl
  • Archived transcripts, when present: ~/.codex/archived_sessions/**/*.jsonl
• Pi
  • Transcripts: ~/.pi/agent/sessions/**/*.jsonl
  • Directories are grouped by slugified working directory; each filename contains the start timestamp and session ID.

Treat these as defaults, not proof that no other store exists. Respect harness-specific environment overrides when present, and inspect the installed harness configuration if a default directory is missing.
