/**
 * Resolve "the rows" from any CLEO operation payload (T12077).

 * The key list itself lives in `@cleocode/contracts` as const data
 * ({@link COLLECTION_KEYS}); this module holds the runtime helper, because
 * `packages/contracts` is types-only (architectural Gate 10).
 *
 * See the contracts module for the three separate outages that motivated a
 * shared SSoT — most severely the sentient loop, which read `data.tasks` from
 * an SDK call returning bare `{results, total}` and therefore picked zero
 * tasks on every tick for three months while reporting "no unblocked tasks
 * available".

/**
 * Resolve the first list-shaped collection on a payload.
 *
 * Accepts BOTH the enveloped shape (`{data: {results: […]}}`) and the bare
 * shape the SDK returns (`{results: […]}`). Confusing those two is precisely
 * what made the sentient loop inert, so this helper deliberately handles both
 * rather than making each caller guess which surface it is holding.
 *
 * @param payload - an operation response, enveloped or bare.
 * @returns the matching array, or `undefined` when the payload carries none.
 *
 * @example
 * ```ts
 * pickCollection({ results: [{ id: 'T1' }], total: 1 }); // → [{ id: 'T1' }]
 * pickCollection({ data: { tasks: [{ id: 'T2' }] } });   // → [{ id: 'T2' }]
 * pickCollection({ total: 0 });                          // → undefined
