`compression.deflate_decompress` expands a raw RFC 1951 DEFLATE byte stream into bytes. The Rust kernel enforces `max_output_ratio = 1024` by deriving the maximum output size from the compressed input length before decoding and rejecting any literal or match copy that would exceed that cap. Raw DEFLATE has no O(1) uncompressed-size header, so the cap is enforced before every output write.
