- task schema: optional sessionForkFrom (source session name); requires session target; self-fork rejected - runner: resolves source newest .jsonl (fail 4 if none/outside dataRoot); passes MOSAIC_SESSION_FORK + MOSAIC_SESSION_DIR; result records lineage - pi adapter: --fork <source> --session-dir <target> when forking; ephemeral default unchanged; plain session resume unchanged - compose passthrough; RELEASE -> 0.0.7 (adapter changed) - suite +9 cases (58 total): plumbing via mock stderr, validation negatives, live fork - child recalls ancestor code word, ancestor session file untouched Closes #33
