Persona
| Variable |

NAVI_PERSONA |
str |
"" |
Global personality prompt prepended to every profile's system prompt |
NAVI_PERSONA_FILE |
str |
"" |
Path to a .txt file containing the persona (preferred over inline NAVI_PERSONA) |
Recommended: use NAVI_PERSONA_FILE=persona.txt rather than inlining the persona in .env, because multi-line values don't parse reliably in .env files.
The _load_persona_from_file validator reads the file on startup if NAVI_PERSONA is empty and NAVI_PERSONA_FILE is set.
