#  Nasiko — server environment reference
#
#      cp server/.env.example server/.env      # then edit
#      just run                                # sources server/.env
#
#  This is the COMPLETE list of environment variables the OSS server reads.
#  The root `.env.example` is the shorter docker-compose quick start; this file
#  is the annotated reference for every knob, and the one `just run` sources.
#
#  NEVER commit server/.env (it is gitignored).

#
#  HOW TO READ THIS FILE
#  • REQUIRED  → the server exits at startup if missing or invalid.
#  • Everything else is commented out and shows its built-in default, so an
#    uncommented line is always a deliberate override.
#  • Values shown as `(unset)` have no default — the feature is off until set.
#
#  Boot requires DATABASE_URL, REDIS_URL, SECRETS_ENCRYPTION_KEY, JWT_SECRET
#  and S3_SECRET_KEY (sections 1 and 4). Bootstrap login additionally needs
#  ADMIN_USERNAME and ADMIN_PASSWORD. The supplied values are for local demos;
#  replace the encryption/signing keys and admin password before first boot.
#  Features have additional requirements: local coding-agent routing needs
#  AGENT_JWT_SECRET (section 6), and telemetry needs section 12 configured.
#  Docker Compose supplies the infrastructure/telemetry URLs automatically.

# ═══════════════════════════════════════════════════════════════════════════
# 1) REQUIRED

# --- Connection URLs ---------------------------------------------------------
# REQUIRED. Under docker compose these are overridden with service names.
DATABASE_URL=postgres://nasiko:nasiko@localhost:5432/nasiko_dev
REDIS_URL=redis://localhost:6379

# --- Security keys -----------------------------------------------------------
# REQUIRED. AES-256-GCM key encrypting agent secrets at rest. Must be exactly
# 32 bytes, base64-encoded — the server validates this at startup and refuses
# to boot on a malformed key. Generate one with:  openssl rand -base64 32
SECRETS_ENCRYPTION_KEY=kmd9Ic4cgD9YYE/owDL3QSzpKI/BZ3pmVZQ67X+eABc=

# REQUIRED. Signs user session JWTs.  openssl rand -base64 48
JWT_SECRET=dev-secret-change-me

# --- Bootstrap admin ---------------------------------------------------------
# Needed for first-login bootstrap, not a startup validation requirement.
# Both must be set for the server to create the admin account.

# Base URL deployed agents use to reach the router. For a host-run server with
# Docker agents, use http://host.docker.internal:8080 where supported, not

# 8) CHAT CONTEXT  — how much conversation history is replayed
# ═══════════════════════════════════════════════════════════════════════════

# Each user picks a strategy (pacms|topk|lastk) and a tier (low|medium|high)

# `topk`/`lastk` read the same tier as an item count:

# The platform's widest window. The MCP gateway and the LLM router both refuse
# to serve a flow older than this, so nothing an agent turn depends on may
# outlive it.
# NASIKO_FLOW_TIMEOUT_SECS=600

# Redis TTL for the flow's guard state. Defaults to the flow timeout + 60s and
# must ALWAYS exceed it: the guard reads `started_at` out of this key, so a
# shorter TTL expires the state the timeout check depends on — the check then
# passes silently and the depth/fan-out counters reset mid-flow.
# NASIKO_FLOW_STATE_TTL_SECS=            # (flow timeout + 60)

# Budget for one agent hop: the A2A proxy, the orchestrator's streaming and
