/**
 * `src/services/observability/observability-schema.ts`
 *
 * The wire format for slice-topology observability events: the schema version,
 * the category and subagent-role vocabularies, the zod schema that is the
 * source of truth for a `slices.jsonl` record, the emit-side contract types
 * (`EmitOptions` / `EmitFailureReason` / `EmitResult`) and the
 * `OBSERVABILITY_CONSTANTS` roll-up over them.
 *
 * Extracted verbatim (wave-3C of the file-size cap campaign) from
 * `observability-service.ts`, which imports what it uses and re-exports every
 * PUBLIC name below, so importers keep resolving all of them from
 * `observability-service.js` unchanged. No emit or read logic lives here — the
 * writer and the reader stay in the service module.
