Replace broad except Exception with specific exception types in 6
sites where the expected failure mode is well-defined:
- normalize.py: OSError for file read, ImportError for optional import
- miner.py: OSError for file read_text
- entity_detector.py: OSError for file read in scan loop
- convo_miner.py: (OSError, ValueError) for normalize which reads
and parses files
- entity_registry.py: (URLError, OSError, JSONDecodeError, KeyError)
for Wikipedia lookup fallback
ChromaDB except Exception sites (~30) are left broad for now.
chromadb.errors defines NotFoundError, DuplicateIDError,
InvalidDimensionException etc., but narrowing those sites requires
importing from chromadb.errors and validating across supported
versions (>=0.4.0). MCP server handlers also left broad for
resilience.
Add Milla's conversational explanation of the palace architecture
(wings → rooms → closets → drawers → halls → tunnels) as an
introductory section before the technical diagram.
