+### Patch Changes

+- [#30](https://github.com/stainless-code/layers/pull/30) [`9d804c2`](https://github.com/stainless-code/layers/commit/9d804c20018d021ab6615b5b064801e6feff3edd) Thanks [@SutuSebastian](https://github.com/SutuSebastian)! - Add `cancelAll` and `LayerCancelledError`: system teardown (parent-dismiss child drain, layer-group dispose, host disconnect) now **rejects** `open()` instead of resolving `undefined`. User `dismiss` / `dismissAll(response)` still complete with `R`. Narrow with `isLayerCancelledError`. Devtools: **Dismiss all** still calls `dismissAll` (resolves); **Force clear** calls `cancelAll` (rejects).

+- [#29](https://github.com/stainless-code/layers/pull/29) [`de3bd7b`](https://github.com/stainless-code/layers/commit/de3bd7bfced94ce91606388c4cfe921782f949bc) Thanks [@SutuSebastian](https://github.com/SutuSebastian)! - Reject non-JSON-safe layer key segments with `LayerKeyError` from `hashKey` (before stringify). Previously `JSON.stringify` could collide `[undefined]` / `[null]` / `[NaN]` as `"[null]"`.

Opt into `onLoadError: "advance"` to remove the failed layer and drain the queue.
