### Description (declared)

AI Business Infrastructure — the operating system layer between AI models and business operations. Model-agnostic. 32 AI agents in the registry, curated MCP connector tools (185 declared, scoped per tenant) over a 1540-verb registry, 54 industry templates, multi-tenant RLS across 446 tables (verified 2026-04-20). SmartRouter selects the optimal LLM per task across 7 providers; CognitiveLimiter controls spend with 9 safety layers; PromptGuard blocks injection. Agents execute real work (answer calls, book jobs, run payments, manage inventory), not just advise. Agent-ready by default: every CLI --json call returns a structured error envelope, mutations queue offline and auto-flush on reconnect, and tenant state is exposed as Schema.org + solid:* JSON-LD walkable via `solid graph`.
