+"""Phase 07.12-02: assert dead knobs and orphan helpers are removed.
+
+Closes / / / (RE-ASSERTED per CONTEXT D-08).
+The four knobs were declared in profile.PROFILE_KNOBS but never read in
+production scoring or response code (see CONTEXT.md §Origin audit table,
+revised 2026-04-30). This phase removes them rather than inventing taxonomy
+that doesn't exist (sensory channels / event-vs-time anchors / somatic-vs-
+labelled tags) or promoting a passive design invariant (double_empathy)
+to a runtime knob.
+
+Two orphan helpers (_apply_verbosity_level, _apply_surface_language) read
+profile fields that are NOT in the KnobSpec registry. Plan 07.12-02 deletes
+both helpers and removes them from the dispatch tuple — they were Phase-5
+legacy noise burning ~5 µs/call.
+
+After Phase 07.12-02:
+- registry holds 11 knobs (10 AUTIST + 1 wake_depth)
+- profile_set on each removed knob returns the unknown-knob error
+- apply_profile dispatch tuple no longer references either orphan helper
