+"""Autonomy router for deep-research's approval gate.
+
+Runs after verify_sources. When the `autonomy` variable is
+'autonomous' (the run was spawned by another agent — architect or
+sisyphus research tiers — with no human at the terminal), the report
+skips the human approval node and ends accepted: the reflexion loop
+already served as the quality gate, and end_autonomous carries the
+source check + pipeline notes with the report so the caller sees them.
+Any other value (default 'supervised') proceeds to the human approval
+gate unchanged.
+
+Routing (`_next`):
+  - autonomy == 'autonomous' -> end_autonomous
+  - anything else            -> approve
+
+Fail-safe: a crash here fails FORWARD via the node's `next` to
+`approve` — the safe, human-gated direction.
