Mimic 2.0

Audit-grade stress-testing SDK for any financial institution — with reinsurance treaty pricing as the lighthouse vertical.

This repo is a monorepo (uv workspace). The build plan is in PLAN.md; agent operating instructions are in CLAUDE.md.

Invariants

1. Auditability — every run produces a world_state_hash and signed event log.
2. Composability — every capability callable from a Temporal workflow.
3. Schema-canonical — bind to FIBO / ACORD / ISO 20022 / FpML, do not invent types.

Quickstart (coming, day-30 target)
