Phase 1 of the majordomo build: - llm/ canonical contract (messages, parts, tools, capabilities, streaming, Model/Provider, error classification) - health/ clock-injected tracker (threshold bench, exponential capped cooldown, reset-on-success) - root Registry + Parse (verbatim model ids, inline recursive alias expansion with cycle detection, chain dedup), LLM_* env-DSN providers (go-llm parity: lazy fallback + eager LoadEnv), health-aware chain executor behind the Model interface - provider/fake scriptable test provider; hermetic test suite incl. the trailing-thinking chain and foreman:// env loading - ADRs 0001-0008, CLAUDE.md, README (honest matrix), CI workflow, docs/phase-1-design.md Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
