/**
 * # blotter/types — the Blotter v1 typed record (kestrel-a57.1, ADR-0011; epic a57 schema)
 *
 * The **Blotter** is the deterministic projection of one Session {@link ../bus Bus} into the canonical
 * typed record of that Session (CONTEXT: Blotter). The Bus is the truth; the Blotter is its projection —
 * regenerable, byte-stable, never a second writer (ADR-0010). This file is the SHAPE only; the fold that
 * produces it is {@link ./project.ts}, its canonical bytes are {@link ./serialize.ts}, and the
 * determinism leg that proves the fold is pure is {@link ./certify.ts}.
 *
 * Two orthogonal stamps ride a Blotter and must never be conflated (ADR-0011):
 * **Certification** — is this record faithful and reproducible? (a set of pass/fail/na legs; the
 * determinism leg is a57.1's, the paper/live legs land in a57.3) — and **Fidelity** — how real are its
 * fills? (the `modeled|realized` level from the graded META, plus the judge's self-limitation stamp — what
 * it could NOT observe — derived from the fill model in a57.4). Certified never means good.
