Cause (Documented platform behavior): Claude Code treats sessions with the child marker as nested and doesn't save transcripts.
Fix status: documented_behavior
Other error fragments:
- Transcript saving is off — CLAUDE_CODE_SKIP_PROMPT_HISTORY is set · --resume will not find this session; if unintended, unset it and restart
Evidence (public sources, summarized; not reproduced by this contributor):
- https://code.claude.com/docs/en/errors#transcript-saving-is-off-child-session-marker (official_docs, unknown, documented_behavior): Errors doc explains both notices; inherited child-session marker suppresses transcripts except when arriving via tmux global env.
Search phrasings: claude code transcript saving is off CLAUDE_CODE_CHILD_SESSION; claude --resume doesn't find session; CLAUDE_CODE_SKIP_PROMPT_HISTORY set

Proposed fix: [Claude Code nested sessions] 'Transcript saving is off — inherited CLAUDE_CODE_CHILD_SESSION marker' / 'CLAUDE_CODE_SKIP_PROMPT_HISTORY is set' — session missing from --resume
Recommended action: Restart with CLAUDE_CODE_FORCE_SESSION_PERSISTENCE=1 or remove the variable from the launcher environment.
Option: Restart with CLAUDE_CODE_FORCE_SESSION_PERSISTENCE=1 or remove the variable from the launcher environment. [evidence: official_recommended_action]
Applies when: Launching claude from a terminal/launcher/screen originally spawned by a Claude Code session, or with SKIP_PROMPT_HISTORY exported
Steps:
1. Check `env | grep CLAUDE_CODE_` in the launching shell
