# NEXT_PUBLIC_PRO_WORKBENCH_ENABLED; set it alone to enable the classroom

# NEXT_PUBLIC_VIDEO_EXPORT_CTA_DESTINATION=open.maic.chat

# --- Agent Runtime (experimental) ---------------------------------------------

# Server-only gate for durable background agent sessions: the /api/agent
# session and owner-event control-plane routes plus the in-process session
# runner. Default OFF — while disabled, every /api/agent/sessions* and
# /api/agent/owner-events route answers 404. Truthy values are "true" or "1";
# anything else (including unset) is treated as disabled.
# OPENMAIC_AGENT_RUNTIME_ENABLED=true

# The runtime is server-backed and requires the PostgreSQL connection from the
# "Server-backed Persistence" section below: without a non-empty DATABASE_URL
# the runner never starts and the session store rejects requests, even with the
# flag above enabled.
# DATABASE_URL=postgres://openmaic:password@postgres:5432/openmaic

# REQUIRED while the runtime is enabled: MODEL_ROUTES must explicitly route the
# "maic-agent-driver" stage to a provider-prefixed model id. There is
# intentionally no fallback — without this route every agent session fails at
# run start. The route object must set api (or its alias dialect) to
# "openai-completions" or "openai-responses"; any other value is rejected, and
# a bare model id without a provider prefix is rejected too. Optional fields:
# contextWindow pins the effective context window below the provider catalog
# value (used by compaction thresholds), and thinking must never set effort
# (the tool-using driver cannot combine reasoning_effort with function tools on
# this transport).
# MODEL_ROUTES='{"maic-agent-driver":{"model":"openai:gpt-5.5","api":"openai-completions"}}'

# Runner tuning. Defaults are shown; only relevant once the runtime is enabled.

# OPENMAIC_AGENT_RUNTIME_MAX_CONCURRENT=2
# OPENMAIC_AGENT_RUNTIME_MAX_ATTEMPTS=5

# Global per-tool-call execution bound for every agent run (ms). A tool call
# that neither resolves nor rejects within the budget is aborted and settles as
# an error tool-result the agent can retry or proceed from; the session does
# not die. Default 600000 (10 minutes). Tools with known longer budgets (media
# synthesis, material extraction) carry their own explicit bounds in code.
# OPENMAIC_AGENT_TOOL_TIMEOUT_MS=600000

# Conversation compaction is reserved and OFF by default. The reusable
# compaction runtime is not implemented yet — it lands in a later slice of
# work — and until then the runner runs without context transformation, so
# these knobs are inert placeholders.
# OPENMAIC_AGENT_COMPACTION_ENABLED=true
# OPENMAIC_AGENT_COMPACTION_RESERVE_TOKENS=0
# OPENMAIC_AGENT_COMPACTION_KEEP_RECENT_TOKENS=0

# Session prompts and follow-up messages are capped server-side at a fixed

# --- Proxy (optional) --------------------------------------------------------

# HTTP_PROXY=
# HTTPS_PROXY=
# Comma-separated hosts that bypass the proxy. Supports domain suffixes and *.
# NO_PROXY=localhost,127.0.0.1,.internal.example.com

# --- Misc ---------------------------------------------------------------------

# Server-side default model for API routes like /api/generate-classroom.
# Required for server-side stages (those that don't receive a client x-model):
# resolveModel throws if a stage resolves to no model (no MODEL_ROUTES entry, no
# x-model, no DEFAULT_MODEL) — there is intentionally no hardcoded vendor fallback.
# Example: anthropic:claude-3-5-haiku-20241022 or google:gemini-3-flash-preview
# OpenAI example: openai:gpt-5.5
# MiniMax example: minimax:MiniMax-M2.7-highspeed
# Bedrock example: bedrock:us.anthropic.claude-sonnet-5
DEFAULT_MODEL=

# Optional per-stage model routing (#745). A JSON object mapping a generation
# stage to a model string (`provider:model`). Resolution order for a stage:
# stage route > x-model (client) > DEFAULT_MODEL. A configured route is the
# operator's deliberate choice and wins even when the browser sends its saved
# model as x-model. Unset = identical to today (everything uses DEFAULT_MODEL).
# Unlisted stages fall back to x-model then DEFAULT_MODEL, so you can override
# just one or two and leave the rest to the client/default.
# At boot the server validates MODEL_ROUTES / DEFAULT_MODEL / <PREFIX>_MODELS
# and prints [config] warnings for unknown stages, unregistered providers,
# providers with no API key, and bare model ids (which still default to openai
# but are deprecated — write provider:model). Warnings only: the server starts
# regardless, so a bad value is caught here instead of at request time.
# Routable stages: scene-outlines-stream, scene-content, scene-actions,
# agent-profiles, quiz-grade, pbl-chat, pbl-v2-runtime, chat-adapter,
# generate-classroom, web-search-query-rewrite, maic-agent,
# maic-agent-driver.
# scene-content can also be routed per scene type with composite keys:
# scene-content:slide, scene-content:quiz, scene-content:interactive,
# scene-content:pbl. A type falls back to the base scene-content route when it
# has no key of its own (so scene-content:<type> > scene-content > x-model >
# DEFAULT_MODEL).
# pbl-v2-runtime follows the same composite fallback pattern with
# pbl-v2-runtime:instructor, pbl-v2-runtime:open-task, pbl-v2-runtime:evaluate
# and pbl-v2-runtime:simulator, falling back to the base pbl-v2-runtime route.
# maic-agent-driver is REQUIRED when the agent runtime is enabled; see the
# "Agent runtime (experimental)" section for its api/dialect constraints.
# A route value can be a model string, OR an object {"model","thinking"} where
# `thinking` is the full ThinkingConfig: mode (default|disabled|enabled|auto),
# effort (none|minimal|low|medium|high|xhigh|max), level (minimal|low|medium|
# high, Gemini), enabled (bool), budgetTokens (number), excludeReasoningOutput
# (bool). It is normalized per the model's capability. When a stage is routed:
# a set `thinking` wins over the client's thinking; with no `thinking` the routed
# model uses its own default and the client's thinking is dropped. Unrouted
# stages keep the client thinking.
# Example: cheap default, stronger model only for the heavy/conversational stages:
# MODEL_ROUTES='{"scene-content":"openai:gpt-5.4","scene-actions":"openai:gpt-5.4","pbl-chat":"anthropic:claude-sonnet-4","chat-adapter":"anthropic:claude-sonnet-4"}'
# Example: per scene type + pinned thinking (qwen budget, deepseek off):
# MODEL_ROUTES='{"scene-content:interactive":{"model":"qwen:qwen3.7-plus","thinking":{"enabled":true,"budgetTokens":8000}},"scene-content:quiz":{"model":"deepseek:deepseek-v4-pro","thinking":{"enabled":false}}}'
# MODEL_ROUTES=

# LOG_LEVEL=info
# LOG_FORMAT=pretty
# LLM_THINKING_DISABLED=false

# Opt-in parallel scene-content generation (#572). 0/unset = serial (default).
# A value > 1 fetches scene content concurrently (capped at 10); actions + TTS
# stay serial. Leave off if your API key has a low per-key concurrency quota.

# --- Local/Self-hosted Deployment ---------------------------------------------
