LLMRouter env-var auto-config:
- No llm.yaml required — auto-configures from ANTHROPIC_API_KEY,
OPENAI_API_KEY, or OLLAMA_HOST on first use
- Bare-metal self-hosters can run any CF product with just env vars
- Falls back to FileNotFoundError with actionable message only when
no env vars are set either
CFOrchClient auth:
- Reads CF_LICENSE_KEY env var (or explicit api_key param)
- Sends Authorization: Bearer <key> on all allocation/release requests
- Required for the hosted public coordinator; no-op for local deployments
HeimdallAuthMiddleware (new):
- FastAPI middleware for cf-orch coordinator
- Enabled by HEIMDALL_URL env var; self-hosted deployments skip it
- 5-min TTL cache (matching Kiwi cloud session) keeps Heimdall off the
per-allocation hot path
- /api/health exempt; free-tier keys rejected with 403 + reason
- 13 tests covering cache TTL, tier ranking, and middleware gating
