Dieses Netzwerk bietet eine Sache: ein Sample, das baut. Es hat es in einer Sandbox ausgeführt und die signierte Quittung behalten. Es bewertet nichts und garantiert nichts — ob derselbe Code bei Ihnen baut, hat es nicht gemessen.
Wie viele verschiedene Signaturschlüssel eine bestandene Vertragsquittung eingereicht haben. Einer ist der Autor allein; mehr als einer heißt, jemand anderes hat es auch gebaut. Ein Schlüssel wird selbst erzeugt und hat keine registrierte Identität dahinter — gezählt werden Schlüssel, nicht Personen.

Contract
- assert setting NaN on an atom holding NaN is a no-op under Object.is and triggers zero notifications, whereas strict inequality (!==) in earlier versions triggered notifications
- assert setting -0 on an atom holding 0 notifies listeners because Object.is(0, -0) is false, whereas strict equality (===) treated them as identical
- assert overriding $atom.eq allows custom equality functions to suppress listener notifications and keep previous object references when values are semantically identical
- assert map.eqKey compares existing and incoming field values with Object.is(prev, next, key), skipping object cloning and listener notification when values match
- assert an uncaught error thrown inside one listener during notify does not abort the notification loop: all subsequent listeners in the queue still execute before the error is rethrown
- assert effect runs immediately upon registration with unpacked positional arguments, mounts all passed stores by incrementing their listener counts, and executes cleanup functions before re-runs and on disposal
- assert onSet interceptors execute in reverse registration order (reduceRight) and pass a mutable shared context across interceptors
- assert calling abort() inside an onSet interceptor halts the mutation before store value update and notifies zero listeners
- assert onNotify interceptors can abort listener notifications while keeping the store value update intact
- assert onStart fires synchronously upon first subscription, onStop fires synchronously upon the last unbind, whereas onMount unmount cleanup is deferred by STORE_UNMOUNT_DELAY (1000ms)
- assert batched defers recomputations across rapid dependency updates via timer debouncing while computed recalculates synchronously on every change, and reading batched with .get() synchronously flushes the calculation
- assert subscribeKeys immediately primes the listener with current store value whereas listenKeys only fires on subsequent mutations, and listenKeys matches nested prefix keys upon dotted path updates
- assert mapCreator returns cached singleton stores by id while active and automatically evicts cached instances once unmounted after STORE_UNMOUNT_DELAY
- assert setPath and setByKey are immutable data transformation utilities that return cloned objects without mutating the original source, while getKey safely traverses nested paths from store state
- assert cleanStores resets store state in development mode and unmounts active stores synchronously
