+Subject: [PATCH] Async-read view for LevelChunkSection
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Adds an opt-in AsyncReadView API on LevelChunkSection that lets a worker
+thread sample BlockState and Biome values from a stable snapshot of a
+section's PalettedContainers without blocking main-thread writes.
+
+acquireAsyncSnapshot deep-clones the live PalettedContainer.Data once,
+publishes the clone as the new live container, and returns the original
+to the caller. Subsequent writes (synchronised or unchecked) mutate the
+published clone in place, so the snapshot held by the caller is never
+touched. The write path stays byte-identical to upstream — no read
+counter, no copy-on-write branch, no race with getAndSetUnchecked.
+
+Cost is one Data clone per acquire, equivalent to LevelChunkSection.copy().
+The win over copy() is API shape: the caller gets a typed AutoCloseable
+view backed by a single Data ref instead of a full LevelChunkSection
+wrapper carrying stale block-count fields, leaving room to evolve a
+smarter sharing scheme later.
