Module ontology_loader 

Startup ontology loader — parses bundled Turtle/N-Triples ontology files into NQuins and seeds the daemon graph at startup.

Ontology files are resolved in priority order:

1. $QUALIA_ONTOLOGY_PATH/ environment variable if set
2. ontologies/ relative to the current working directory (dev / workspace layout)
3. Alongside the binary: <exe-dir>/ontologies/

Any file that cannot be read or parsed emits a log warning and is skipped — the daemon starts successfully even if ontology files are absent.
