Summary

AI summary

Fixed CacheStack graceful degradation on coordinator failure.

Full changelog

Real Redis-backed benchmark harnesses for direct cache behavior, HTTP throughput, edge cases, slow Redis, queue amplification, and multi-process fan-out.
New benchmark utility coverage and Redis single-flight coordinator tests.

Version bumped from 1.2.9 to 1.3.0.
README.md now reflects the current validation baseline with 431 passing tests.

RedisLayer and RedisSingleFlightCoordinator now support per-command Redis timeouts via commandTimeoutMs.
CacheStack now degrades gracefully when the distributed single-flight coordinator fails and preserves local single-flight collapse for concurrent misses.
StampedeGuard now shares in-flight promises across concurrent callers instead of serializing them through a mutex queue.

About flyingsquirrel0419/layercache

v4.0.0 Write coordination applies finite default limits and can reject saturated work with CacheWriteSaturationError.
v4.0.0 Automatically derived structured `wrap()` keys now use the `j2:` schema; old `j:` entries become cold misses and expire naturally.
v4.0.0 Read-through fetchers now cache null as a regular value by default; `getOrThrow()` returns stored nulls while throwing only for undefined.
v4.0.0 Public CacheStack reads now return undefined for misses and negative-cache entries instead of null.
