+# "exceeds the available context size (4096 tokens)" in practice, which
+# qwen-code surfaces as "Auto Mode couldn't classify this action

+# a single slot instead of raising ctx-size (no extra VRAM, and this
+# service doesn't need concurrent classifier calls the way the main
+# model needs concurrent chat sessions) — the full 8192 now goes to the
+# one slot. If hints.allow/softDeny/hardDeny ever approach their
