# CSM Reference Runtime v0.1 — Implementation Closure Report

## Result

- Full regression: **52/52 PASS**
- Runtime conformance + NS_GSM seed assertions: **24/24 PASS**
- Genesis ledger events: **89**
- Native/replay state hash: `8137913b7f32eab68ebe2490b2e678bdaea5dd8c74b6225b1384300a76f4c3ee`
- Replay exact match: **PASS**
- Wheel build: **PASS**
- Installed-wheel import + seed-run + replay-check: **PASS**

## Seed semantic closure

- Formal NS root: `OPEN`
- C1 Chain Necessity: `OPEN`
- C2 Finite Obstruction: `OPEN`
- D104 narrow frozen/fixed-positive-viscosity no-go: preserved in declared scope
- D104 shear / axisymmetric branches: `OPEN + SURVIVOR`
- D105 uniformity correction: recorded as `SCOPE_REVISION`
- D105 viscosity-matched shear/polarization: `OPEN + SURVIVOR`
- D105 first-order solvability / spectral-drift: active `FRONTIER`
- Dataset scope: `observed-relative`

## Active frontier

1. `frontier:c1-chain-necessity`
2. `frontier:c2-finite-obstruction`
3. `frontier:c6q-six-way`
4. `frontier:d105-first-order`

## Authority closure

A final regression was added for certificate-type authority: an `OPCERT` cannot be reused as a positive or negative theorem certificate, and an ordinary proof certificate cannot be used as a route-block certificate.

## Explicit nonclaim

This runtime result is software/runtime closure only. It does not prove Navier–Stokes global regularity or route completeness.
