Each command resolves your LiteLLM key (logging in via SSO when none is stored and you are at a terminal; otherwise it expects `LITELLM_PROXY_API_KEY` or `--api-key`), checks the key against the proxy so bad credentials fail immediately instead of deep inside the agent, exports the environment variables the agent reads, then replaces itself with the agent process.
The right variables are picked per agent. Claude Code gets `ANTHROPIC_BASE_URL` (the proxy root, so it appends `/v1/messages`) and `ANTHROPIC_AUTH_TOKEN`, with any stray `ANTHROPIC_API_KEY` cleared so the proxy token wins, and `ENABLE_TOOL_SEARCH=true` (unless you already set it) so Claude Code keeps tool search on even though the base URL is a proxy rather than a first-party Anthropic host. It also gets `CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY=1` (again unless you already set it) so Claude Code v2.1.129+ fills its `/model` picker from the proxy's `/v1/models`; Claude Code only lists entries whose id contains `claude` or `anthropic`, and older versions ignore the variable. Export it as `0` to turn discovery off. Codex and OpenCode get `OPENAI_BASE_URL` (the proxy plus `/v1`) and `OPENAI_API_KEY`. Codex ignores `OPENAI_BASE_URL`, so it is additionally pointed at the proxy through a custom provider passed as `-c` config overrides (HTTP/SSE Responses transport, since the proxy does not speak the Responses WebSocket protocol).

When the list cannot be fetched, `lite opencode` says so on stderr and launches anyway.

keep the classifier deployment or provider default, or set a supported value such as `none` or
`low` to override that call.
Classifier calls have a one-attempt hard deadline. After a timeout, the router opens a process-local
circuit for that classifier and sends every session through `classifier_fallback` for
`classifier_llm_config.circuit_breaker_cooldown_seconds` (30 seconds by default). When the cooldown
expires, one request probes the classifier while concurrent requests continue through the fallback.
A successful probe closes the circuit; a failed probe restarts the cooldown. The circuit breaker is
on by default; set `classifier_llm_config.circuit_breaker_enabled: false` to disable it. The default
fallback is the local heuristic scorer, so a classifier outage does not repeat its timeout across
every turn or session handled by the router process.
A request short-circuits, meaning it routes on the scorer's own tier with no classifier call, when
two things hold: the scorer landed at or below `heuristic_first_max_tier`, and it produced at least
one signal. Everything else goes to the classifier, which then decides as it normally would.

fact on a session that already holds a pin, so it must not overwrite the pin it displaced.
An open classifier circuit is the shortest-lived state of all: the fallback ran because the
breaker skipped the classifier, not because the request got classified, and the cooldown is
seconds against a TTL of an hour that every later turn refreshes. Its cause is whatever the
fallback path reports, so the circuit signal is what marks the decision, and leaving it
unpinned lets the session classify again as soon as the breaker closes.
A health failover describes the fleet's state right now, not the session's traffic, and it can
displace decisions that were themselves unpinnable (a housekeeping call, a modality escalation).
Pinning it would hold the session on the substitute long after the displaced group recovers; the
gate re-fires per request, so leaving it unpinned costs nothing but the classifier call.

Regression for LIT-3798. A streaming /v1/messages request whose client disconnected
before the provider failed mid-stream never reached the proxy's failure hook: the
client-facing generator was gone, and the detached upstream drain only fired the
logging object's callbacks, so no failure spend row was written and the budget
reservation stayed held. base_process_llm_request now arms a closure on the logging
object that the detached drain awaits, and that closure runs post_call_failure_hook
with the request's key and data.
