/**
 * Type surface for the evidence ledger. The implementation stays plain ESM
 * JavaScript on purpose; this file is the boundary index.ts may rely on, so a
 * field that is not declared here is a type error at the call site rather than
 * a silent `any`.
 *
 * Suite-run recognition lives in `suite-runs.d.mjs` (split out in 0.17.5): the
 * ledger stores entries, the observer decides what a tool call proved.
