 # সমস্যার ইতিহাস:
-#   v1: llama.cpp source build → OOMKilled (16GB RAM শেষ)
-#   v2: llama-cpp-python==0.3.9, extra-index-url → wheel নেই → source build → gcc নেই → fail
-#   v3: gcc install + llama-cpp-python==0.3.27 build → OOMKilled (16GB RAM শেষ)
+#   v1: llama.cpp source build → OOMKilled
+#   v2: wheel নেই → source build → gcc নেই → fail
+#   v3: gcc install + build → OOMKilled
+#   v4: python:3.10 + Luigi wheel → app startup হয় না (permission)
 #
-# v4 চূড়ান্ত সমাধান:
-#   Direct pre-built wheel URL দিয়ে install → ZERO compilation
-#   Source: sergey21000/llama-cpp-python-wheels (GitHub)
-#   Wheel: llama_cpp_python-0.3.15-cp311-cp311-linux_x86_64.whl
-#   Size: ~4MB, install time: <10 seconds
+# v5 সমাধান:
+#   - python:3.10-slim (Luigi wheel এর জন্য)
+#   - Luigi/llama-cpp-python wheel (Gemma 4 সাপোর্ট, Jan 2026)
+#   - USER root এ চালানো (HFS free tier এ permission সমস্যা এড়াতে)
