+• Implemented: I changed only the hybrid routing logic in main.py to a validation-first strategy instead of raw confidence gating.
+
+  What changed in generate_hybrid:
+
+  - main.py:97 now does:
+
+  1. Run on-device first.
+  2. Infer expected intents from user text (weather, alarm, timer, message, reminder, contacts, play music).
+  3. Validate local output against tool schema (required args + type checks).
+  4. Validate semantic consistency against extracted slots (time, minutes, location, recipient/message, reminder title/time, contact query, song).
+  5. Apply dynamic confidence thresholds by complexity:
+      - single-intent: 0.80
+      - two intents: 0.92
+      - three+ intents: 0.96
+  6. Fallback to cloud only if local output fails semantic/schema checks or confidence threshold.
+
+  Why this should improve your benchmark:
+
+  - It explicitly catches the failure mode you showed: high-confidence but wrong local calls (especially timer/reminder/multi-call hard tasks).
+  - It preserves local speed/ratio when local calls are actually coherent.
+
+  Validation status:
+
+  - Syntax check passed: python -m py_compile main.py.
+  - Full benchmark could not be completed in this environment due blocked network access for Gemini fallback (httpx.ConnectError), so I couldn’t produce a
+    new score locally.
+
+  Next step to verify on your side:
+
+  1. Run python benchmark.py with working Gemini connectivity and compare score/F1 breakdown vs your current 50.0%.
