Environment / auth

ATTESTARI_KEK
secret
Base64 32-byte root key. Set it to enable encryption at rest and cryptographic erasure (forget() destroys the subject's key and signs the certificate). Without it, forget() is a logical delete and certificates are left unsigned.
ATTESTARI_DATABASE_URL
secret
Postgres DSN. Set it to use Postgres + pgvector instead of the default local SQLite file (concurrent access, indexed hybrid search).
ATTESTARI_SQLITE_PATH
Where the default SQLite ledger lives.
ANTHROPIC_API_KEY
secret
Enables Claude-powered fact extraction; falls back to the built-in regex extractor when unset.
