# Copy to .env and fill in real values. Never commit .env (see .gitignore).

# --- Postgres --------------------------------------------------------------
# Bootstrap superuser, used once at first init to create the nuron_ai/nuron_api
# schemas and roles (schema.sql). Application code never connects as this user.
POSTGRES_USER=postgres
POSTGRES_PASSWORD=changeme
POSTGRES_DB=nuron

# Passwords for the two schema-scoped login roles schema.sql creates via psql
# \getenv -- never hardcoded in schema.sql itself.
NURON_AI_DB_PASSWORD=changeme
NURON_API_DB_PASSWORD=changeme

# Host-published Postgres port (see docker-compose.yml) -- nuron-ai isn't containerized
# yet, so it talks to Postgres over the host network, not the `nuron` compose network.

NURON_AI_DB_PORT=5432

# --- Neo4j -------------------------------------------------------------------
# Community edition has exactly one user, `neo4j`, and exactly one database -- no
# NEO4J_USERNAME/NEO4J_DATABASE var, nothing to configure.
NEO4J_PASSWORD=changeme
# Host-published bolt port (see docker-compose.yml) -- nuron-ai isn't containerized yet,
# so it talks to Neo4j over the host network, not the `nuron` compose network.

# --- RustFS ------------------------------------------------------------------
RUSTFS_ACCESS_KEY=changeme
RUSTFS_SECRET_KEY=changeme
# Bucket-only URI plus endpoint: swapping RustFS for MinIO/S3 is an endpoint_url change,
# not a code change (fsspec/s3fs resolve the backend from RUSTFS_URI's scheme).

# --- Embeddings --------------------------------------------------------------
# One-way door once real content exists (ADR-0004): the model id and dimension
# count are baked into the Neo4j vector index at creation time.

# --- PDF extraction ------------------------------------------------------
# Off by default -- dev/test only against LlamaParse (PRD §5.1). Verify current
# per-page credit pricing for the chosen tier before ever setting ENABLED=true
# (docs/tracer-bullet-01.md §7) -- pricing varies by tier and changes over time.

# --- Upload --------------------------------------------------------------
# PHP's `M` ini shorthand is already binary (25M = 25 MiB), matching Laravel's
# `max:25600` KB exactly. post_max_size carries 1 MiB of multipart headroom so an
# oversized file is rejected before Laravel finishes parsing it, not after --
# setting both to the same value would let a 25-26 MiB file be fully parsed first.
UPLOAD_MAX_FILESIZE=25M
POST_MAX_SIZE=26M

# --- Attribution fallback --------------------------------------------------
# Used only when a document's own content has no attribution. Never called
# `author` -- that name is reserved for what a citation actually claims a
# person said or decided (CONTEXT.md).
