+- `NSNR-LOG-012`: synthetic `NewtonChannelDecision`이 아니라 `EvaluateNewtonConvergence`가 만든 residual decisions를 record에 넣는다. Exact-zero matching external channel은 denominator exact `0`, branch `zero-scale`, threshold `1.0e-3`, force 또는 force-length unit으로 직렬화하고, nonzero matching external channel은 retained denominator, branch `relative`, threshold `1.0e-2`, unit `1`로 직렬화한다. 같은 line이 기존 39 labels/order, TAB separation, LF termination을 그대로 유지해야 하므로 기존 selector에서는 RED가 된다.

-Implement a small log writer with explicit open/write/flush/close state, serializer-owned 39-field order, deterministic escaping, finite numeric formatting, `relative`/`zero-scale` convergence branch mapping, typed `not-evaluated(reason)` substitution, and structured `Status` failures.

 - Do not accept arbitrary caller-provided field vectors. 이유: io.md requires an exact fixed schema and order.
