-# Dockerfile for Clawdbot Dev Assistant on HuggingFace Spaces
-#
-# CHANGELOG [2025-01-30 - Josh]
-# REBUILD: Updated to Gradio 5.0+ for type="messages" support
-# Added translation layer for Kimi K2.5 tool calling
-# Added multimodal file upload support
-#
-# CHANGELOG [2025-01-31 - Claude]
-# FIXED: Permissions for HF Spaces runtime user (UID 1000).
-# PROBLEM: HF Spaces run containers as user 1000, not root. Directories
-#   created during build (as root) weren't writable at runtime, causing
-#   ChromaDB to silently fail when trying to create SQLite files.
-# FIX: chown all writable directories to 1000:1000, then switch to USER 1000.
-#
-# ALSO: Added /data directory for HF persistent storage.
-# /data is the ONLY path that survives container restarts on HF Spaces.
-# Must enable "Persistent Storage" in Space Settings for /data to exist.
-# Falls back to /workspace (ephemeral) if /data isn't available.
-#
-# FEATURES:
-# - Python 3.11 for Gradio
-# - Gradio 5.0+ for modern chat interface
-# - ChromaDB for vector search
-# - Git for repo cloning
-# - Optimized layer caching
-# - Correct permissions for HF Spaces (UID 1000)

-# HF Spaces run as UID 1000, not root. All directories that the app needs
-# to write to must be owned by 1000:1000, otherwise ChromaDB, conversation
-# saves, and file downloads will silently fail.

-# /workspace - ephemeral storage (wiped on restart, but works within session)
-# /workspace/chroma_db - ChromaDB fallback if /data isn't available
-# /data - HF persistent storage (survives restarts, created by HF at runtime)
-#   NOTE: /data may not exist at build time. We create it here so the chown
-#   works, but HF may mount over it at runtime. That's fine - HF sets correct
-#   permissions on their mount. This is belt-and-suspenders.

-# ChromaDB downloads its ONNX MiniLM-L6-V2 embedding model on first use.
-# By default it writes to /.cache which is owned by root.
-# Since we run as USER 1000, this causes:
-#   PermissionError: [Errno 13] Permission denied: '/.cache'
-#
-# FIX: Redirect ALL cache directories to /data/.cache (persistent!)
-# This has a bonus effect: the embedding model download persists across
-# restarts too, so subsequent startups are faster (no re-download).
-#
-# If /data isn't available (persistent storage not enabled), these dirs
-# will be created at runtime under /tmp/.cache as a fallback.
