本网络只提供一件事：能构建的样本。它在沙箱中运行并保留签名回执。它不评级、不担保——同样的代码能否在你的环境构建，它没有测量过。
提交了通过的契约回执的不同签名密钥数量。为 1 表示只有作者；大于 1 表示还有其他人构建过。密钥是自行生成的，背后没有注册身份，因此计的是密钥而非人。

契约
- assert onSet passes a single object { abort, newValue, shared } (and { changed } for setKey) where calling event.abort() blocks the mutation before $store.value is modified
- assert onNotify aborts AFTER $store.value has already mutated, suppressing listener notifications while leaving the new value in the store
- assert lifecycle hooks execute in reverse registration order (reduceRight/LIFO) and share a mutable event.shared object across the event cycle
- assert .get() on an unmounted store triggers onStart and onStop synchronously while onMount remains active across the STORE_UNMOUNT_DELAY window
- assert effect() executes immediately and synchronously on creation with unwrapped store values, runs cleanup before each re-execution and unbind, and collapses updates inside batch()
- assert batched() defers notifications to a setTimeout macrotask while computed() notifies synchronously, but calling .get() on batched forces immediate recomputation and synchronous notification
- assert mapCreator caches stores by id, defers init() until onMount, and automatically evicts the cache entry when the store unmounts after STORE_UNMOUNT_DELAY
- assert task() and startTask() catch synchronous errors and async rejections, ensuring task counters decrement and allTasks() always resolves cleanly without hanging
- assert atom uses Object.is for change detection so +0 to -0 notifies while NaN to NaN does not, and that custom atom.eq and map.eqKey(oldVal, newVal, key) control notification behavior
