Add GIGAFACTORY_SYSTEM_OVERVIEW.md — a current-state companion to the roadmap
spec covering: what the Agent Gigafactory is, a completion snapshot, three
Mermaid diagrams (component architecture, job-lifecycle state machine, atomic
claim + lease-fencing sequence), the Cosmos data model, the scoring router,
subsystem map, full /fleet REST surface, feature flags, the two control planes,
a cross-repo code map, test coverage, next steps (Phase 4/5), and an honest
bugs/gaps/risks section. All three Mermaid blocks validated with mermaid.parse.
Also correct documentation drift in GIGAFACTORY_ROADMAP.md found during the
review:
- §0 progress table showed Phase 3 as "0% not started" while every Phase-3 box
is ticked; updated phases 1-3 to done with realistic percentages.
- Phase-2 boxes "scheduler/router wired into assignment", "tracker adapter
direct call", and "factory enrollment + scoped tokens" are implemented in
common-plat (coordinator.ts uses selectJob; routes.ts enforces
enrollment.enforceFactoryToken; tracker-bridge.ts) but were left unticked —
ticked with evidence and refreshed the stale "remaining for 100%" notes.
