 * Grouping key is `workflowId ?? workflowName` — the numeric GitHub Actions workflow database

 * nor a numeric `runId` (status contexts, startup-failure synthetics) never participate: they
 * can neither be marked superseded nor count as evidence of a newer run.
 *
 * A check is superseded iff its own conclusion is `CANCELLED` and some other check sharing its
 * workflow key has a strictly greater `runId`. The newest run for a workflow is therefore never
 * superseded, even if it is itself cancelled — that case stays "failing" so the agent can decide
 * whether to rerun it.
 *
 * @returns Indices into `checks` (not object identities, since check-run objects are not
 *   deduplicated by reference elsewhere) that should be reclassified as "superseded".
