…K transcript exists
After a bridge restart the in-memory _runtime_active_sessions set is empty,
so _effective_session_id rejected every persisted session_id ("Ignoring
persisted session_id ... not active in current runtime") and each
conversation started blank — diagnosed as PATH1 memory loss (2026-07-08,
daegyo node, diag-memory.sh: PATH1 marker x1, PATH2 markers 0).
Fix: a persisted session_id not in the runtime set is now auto-resumed when
its SDK conversation JSONL transcript still exists under
~/.claude/projects/<project>/ (validated via resolve_conversation_file, so
corrupt/traversal ids cannot escape the directory). Stale ids without a
transcript are still ignored, preserving the original cross-process safety
intent. Off-switch: CCC_RESUME_PERSISTED_SESSIONS=false restores the old
never-resume behavior.
- new pure helper core/session_resume.py (+8 unit tests, all green)
- full suite: 476 tests, same 7 pre-existing env failures on clean main
(voice/path-scope, Termux env) — no regression from this change
