Review this generated summary cache before it handles application requests.
Cache a public payload summary by request identity without keeping requests alive, reject invalid request shapes, never expose tokens or mutable cached data, and do not promise an entry count.

const summaries = new WeakMap();
function summarizeRequest(request) {
const cacheKey = { id: request.id };
if (summaries.has(cacheKey)) {
return summaries.get(cacheKey);
}
const fields = Object.keys(request.payload).sort();
const summary = {
id: String(request.id),
fields,
token: request.token,
};
summaries.set(cacheKey, summary);
return summary;
}
function cachedCount() {
return summaries.size || 0;
}
