Per board directive on INB-20: - live pipeline: INBOXOS_LLM_MODEL=INBOXOS_LLM_MODEL_EXTRACT=gemma4:31b-cloud (single model, no escalation) - historical pipeline: INBOXOS_LLM_MODEL_CHAIN='gemma4:e4b,gemma4:12b,gemma4:31b-cloud' (primary, smart retry, 2nd smart retry) - LLMConfig now has a model_chain field parsed from INBOXOS_LLM_MODEL_CHAIN; ollama_run_command_with_chain + llm_run_command_with_chain implement the chain as the retry policy (no same-model tenacity, so a flaky cheap model does not multiply wall-clock latency) - precedence flip in ollama_run_command: per-step env-var model wins over prompt frontmatter, so an operator can pin a pipeline-level model without editing prompt files - .opencode/commands/inboxos:*.md frontmatter updated to gemma4:e4b (matches the historical primary; the live env var overrides to 31b-cloud at runtime) Offline tests: 14/14 live, 8/8 historical unit (incl. new test_process_escalation_recovers_on_second_model) pass. Live Ollama smoke: gemma4:31b-cloud correctly classifies a test email via the live pipeline path; gemma4:e4b → escalation chain routes through to gemma4:31b-cloud when needed.
