"""Spawn-session task_id attribution warning (#11).

A developer / QA / documenter spawn always works a concrete task — a spawn row
with ``task_id IS NULL`` is an unattributed-cost bug (the usage rollup can't tie
the spend to a task). Intake (prompter), secretary, auditor, and PMs legitimately
spawn taskless, so they are NOT flagged. The pure predicate lives next to the
spawn recorder so the warning fires only for the genuine signal.
