/**
 * Generate the per-subsystem Cordis service/event reference regions from the
 * Typert catalog projection. Every harness `ctx.<key>` service and event scope
 * maps to exactly one `docs/subsystems/` page through the curated tables below;
 * the generator injects each page's Cordis API reference between its GENERATED markers —
 * byte-identically into both language sides of the pair — and re-records a
 * pair's `.i18n.yaml` only when nothing outside the region changed. The
 * projection enforces event modes, JSDoc parameter/return completeness, and
 * signature type-link coverage; the inherited (vendor) tier renders to
 * `docs/cordis-api/inherited.md`. `--check` verifies every generated artifact.
