Environment / auth

AMU_PGVECTOR_DSN
required
secret
Postgres DSN for the role this server runs as. Results are gated by row-level security under this exact role -- use an amu_writer-member role for amu_record/amu_check_conflict, or an amu_agent_base-member role for read-only amu_search.
AMU_PGVECTOR_EMBEDDING_DIM
Embedding vector dimension, used only by the built-in deterministic fallback embedder when sentence-transformers (the amu-pgvector[st] extra) isn't installed. Must match the dimension sql/amu_pgvector.sql was installed with. Default: 1536.
