# Honcho — self-hosted memory server
#
# Runs four services:
#   api       — HTTP API on :8000
#   deriver   — background worker: extracts conclusions, builds peer representations
#   db        — PostgreSQL 17 + pgvector (needed for embedding search)
#   redis     — fast cache for session context
#
# Usage:
#   cp .env.example .env
#   # edit .env and set at least LLM_OPENAI_API_KEY (or another provider)
#   docker compose up -d
#
# The API will be available at http://localhost:8000
# Interactive docs: http://localhost:8000/docs

  # ── Deriver (background worker) ───────────────────────────────────────────
  # Processes incoming messages to:
  #   - extract observations (conclusions) about users
  #   - build peer representations / user cards
  #   - generate session summaries
  #   - run "dream" consolidation passes
  #
  # Without a working LLM key this service will fail to process messages;
  # the API itself will still work but no long-term memory will be built.
