Left alone, the hooks treat it as a\n * session in its own right: they inject project context into it, create and\n * rename a numbered session note for it, autosave it, and enqueue a\n * model-written handover for it. Its compactions also land in the project's\n * transcript folder, where they are indistinguishable from a real session's\n * and drag the measured compaction trigger down (observed 2026-09-17: two\n * workers compacting at ~151k tokens pulled a project's trigger from ~784k\n * to ~151k, and the real session's handover fired at ~50k tokens).\n *\n * The launcher marks such sessions with `PAI_WORKER=1`.
