# --- Authentication (REQUIRED) ---------------------------------------------
# Comma-separated "key:agent" pairs. Each AI/client gets its own key so the
# brain knows who wrote/searched what. Generate strong keys with:
#     python scripts/gen_key.py
#   BRAIN_API_KEYS=Kf3...:claude-code,Qz9...:cursor

# --- Projects --------------------------------------------------------------
# Each project is isolated (own vault folder + own vector collection). Requests
# without a project use this default. Clients can target any project per call.
BRAIN_DEFAULT_PROJECT=default

# --- Embeddings (local, CPU, no data leaves the box) -----------------------
# Default is a lighter multilingual model that fits small (2GB) droplets.
#   Balanced : sentence-transformers/paraphrase-multilingual-mpnet-base-v2 (768)
#   Best     : intfloat/multilingual-e5-large (1024, heavier on CPU)
# NOTE: changing this changes the vector size; the brain auto-rebuilds the
#       affected collection and re-indexes the vault on next start.
EMBED_MODEL=sentence-transformers/paraphrase-multilingual-MiniLM-L12-v2

# --- Vector store ----------------------------------------------------------
# docker-compose sets this to the private qdrant service automatically.
# Leave blank to use an embedded on-disk Qdrant (no separate service).

# --- Dreaming (reflection) -------------------------------------------------
# Cluster notes whose similarity is in [relate, dedup) into digest notes.

DECAY_STEP=1

# --- Optional LLM summarization for /ingest (OFF by default) ---------------
# When true AND an API key is set, long ingested text is summarized before
# storing. Off keeps everything local/private.

# --- Safety: secret / PII redaction (v0.0.1.3) -----------------------------
# When true, detected secrets/PII are scrubbed from content before storing.
# When false (default), they are only reported back in `pii_findings`.

# --- Sleep cycle (v0.0.1.3) ------------------------------------------------
# When true, the sleep cycle archives stale, low-value, never-read memories.
