_getCached()
_getCached<
T>(path,parse,options?):Promise<T>
Defined in: Developer/brk/modules/brk-client/index.js:1918
Make a GET request with layered caching.
Contract:
- The returned Promise resolves with the freshest value (post-revalidation).
onValuefires once with the freshest value, or twice if a stale snapshot could be shown first (stale-while-revalidate). On a 304 there is no second fire.
Layers:
- L1 (memCache): in-memory parsed values keyed by URL+ETag. Lets 304s skip the parse entirely.
- L2 (browserCache): Cache API, survives reload and feeds onValue fast on cold start.

Delta of the projected next block since <hash>. order is the full new template in order: each entry is either a number (index into the prior template the client cached at <hash>) or a transaction object (new body to insert at this position). Walk order once to rebuild; removed is a convenience list of txids that left so clients can evict cached bodies. After applying, use the response hash as <hash> on the next call to keep iterating. Returns 404 when <hash> has aged out of server history; clients should fall back to /api/v1/mempool/block-template.
