# CHANGELOG [2025-01-29 - Josh]
# Created for HuggingFace Spaces deployment
# Handles runtime setup before starting the Gradio application
#
# CHANGELOG [2025-01-31 - Claude]
# Added cache directory fallback for ChromaDB embedding model downloads.
# PROBLEM: ChromaDB tries to download ONNX MiniLM to /.cache on first use.
# Running as USER 1000 means /.cache (owned by root) is not writable.
# Dockerfile sets ENV vars to redirect to /data/.cache, but if /data
# isn't available (persistent storage not enabled), we need a fallback.
# FIX: Test /data writability at runtime. If not writable, redirect
# cache env vars to /tmp/.cache (ephemeral but at least writable).
# Also added startup timestamp and diagnostic logging.
