# The app requires real infrastructure to run: a DATABASE_URL (durable event
# store) and a live inference backend. There is no offline/stub product mode —
# the deterministic stub now exists only as the test suite's mock data. Pick one
# of two inference backends (the Lab's §00 selector chooses per run): the small
# models you serve yourself from `modal/` (see modal/README.md), or Hugging Face's
# serverless Inference Providers (just an HF_TOKEN). Either is small-model-only
# (<=32B); there is no generic OpenAI/cloud path.

# ── Live models: the OpenAI-compatible small models served on Modal ────────────
# (ADR-0014 / 0015 / 0019). Setting MODAL_WORKSPACE activates the live path. Each
# profile in config/models.yaml binds to a model by its *catalogue key*
# (modal/catalogue.py — the single source of truth for what is deployed); the
# engine derives that endpoint's URL as
#   https://${MODAL_WORKSPACE}--<app>-<endpoint>.modal.run/v1
# so the workspace is the only deploy-specific value and is never hard-coded.
# Calls route through the LiteLLM gateway, which meters real per-call cost into
# the Governor's hourly_budget_usd. MODAL_LLM_KEY is the endpoint bearer token —
# a self-served vLLM endpoint accepts any token (default "EMPTY").
#   MODAL_WORKSPACE=your-modal-workspace
#   MODAL_LLM_KEY=EMPTY
MODAL_WORKSPACE=
MODAL_LLM_KEY=

# Alternatively, point at a single explicit OpenAI-compatible endpoint (also
# activates the live path) — one model served on Modal, or a local llama.cpp /
# vLLM box. Used as the base_url for every profile.
#   MODAL_LLM_BASE_URL=https://your-workspace--google-llms-gemma-4-12b.modal.run/v1

# ── Live models: Hugging Face serverless Inference Providers (ADR-0024) ─────────
# A SECOND inference backend, next to Modal — no GPUs to deploy: one HF_TOKEN makes
# many small instruct models callable through HF's OpenAI-compatible router. Setting
# HF_TOKEN activates the live path for the Hugging Face backend; the Lab's "Inference
# backend" selector (§00) chooses Modal vs Hugging Face per run, and the per-agent
# pickers then offer that backend's catalogue (src/models/hf_catalogue.py). Calls route
# through the same LiteLLM gateway as Modal, metering real cost into the Governor.
#   HF_TOKEN=hf_xxxxxxxxxxxxxxxxxxxxxxxx
HF_TOKEN=
# Optional: point the HF backend at a self-hosted TGI / dedicated HF Inference Endpoint
# (same OpenAI-compatible REST API) instead of the public router. Activates live on its
# own (HF_TOKEN then becomes that endpoint's bearer, if it needs one).
#   HF_INFERENCE_BASE_URL=https://your-endpoint.endpoints.huggingface.cloud/v1

# Optional per-profile model override (ADR-0010). Each agent's manifest picks a
# logical profile (tiny/fast/balanced/strong); these override the model string
# bound to that profile in config/models.yaml (highest priority). Every model
# must be <=32B; tiny <=4B. Values are LiteLLM model strings — for a custom
# OpenAI-compatible endpoint that is `openai/<served_model_id>`.

# Durable event store backend (ADR-0014 Postgres) — REQUIRED. The append-only
# ledger is persisted through SQLAlchemy; the app refuses to run without a URL
# (there is no in-memory fallback). Neon (managed Postgres) form:
#   DATABASE_URL=postgresql+psycopg://USER:PASSWORD@HOST/DB?sslmode=require
# A local SQLite URL also works (e.g. a single-box run without a server):
#   DATABASE_URL=sqlite:///runs/events.db
DATABASE_URL=

# Semantic memory index (ADR-0018). Truthy activates a derived vector lens over
# the ledger. Embeddings run LOCALLY via sentence-transformers (no API key;
# cached after first use); sentence-transformers + mem0 ship as core deps.
