Reduce allocations in encrypted RAR reading
...
Reuse bounded buffers and transform AES blocks in place. Remove per-block arrays and plaintext queues, avoid per-byte header allocations, and dispose owned crypto transforms.
Add encrypted RAR benchmarks, regression tests, and before/after profiling results. Full .NET 10 suite passes (2,446 tests); all library targets build and net48 tests compile.

Reduce allocations in RAR5 password key derivation
...
Reuse keyed HMAC state and digest buffers on modern .NET targets while preserving RAR5's three PBKDF2 snapshots. Add independent derivation checks and an allocation regression test.
Profiling on macOS ARM64 with .NET 10 reduced allocations by 99.96%, but showed slower throughput; Alpine-specific timing remains unverified. Full .NET 10 test suite passes.

Reduce Deflate read and Huffman scratch allocations
...
Use a ValueTask read core and memory-based compressed-input refills on modern targets, replace per-block Huffman output arrays with scalar parameters, and decode directly into array-backed caller memory with a pooled fallback.
Preserve generated sync array-read semantics and clear codec output references after reads. Add slice, fallback, cancellation, failure, tree-validation, and read-ahead coverage; document staged ZIP profiles.
Validation: 2,989 .NET 10 tests passed; all library targets, net48 tests, and performance project compile; formatting checks pass.

Pool LZMA workspaces and streamline 7z metadata writing
...
Reuse LZMA2 trial decoders and pooled compressed output, pool and consolidate decoder probability banks, lazily rent encoder optimization scratch, and avoid copying direct async memory writes.
Use bounded stack scratch and stream 7z metadata without temporary property buffers. Add ownership, failure, context-shrink, Unicode, and block-boundary regressions.
Document allocation profiles, the small-file LZMA2 throughput tradeoff, and rejection of exact-size match-finder arrays. Validation: 3,016 .NET 10 tests passed; all library targets, net48 tests, and performance project compile; formatting checks pass.

Reduce 7z copy and LZMA decoder allocations
...
Pool writer CRC-copy buffers, use memory-based async read overloads on modern targets, reuse LZMA2 decoders across resets, and initialize probability-model banks lazily.
Add reset/property-change, memory-read, writer boundary/CRC, and growth regression coverage. Document staged profiling results and rejection of dictionary-growth policies that regress small-file allocations.
Validation: 2,997 .NET 10 Release tests passed, all library targets built, net48 tests compiled, and formatting checks passed.

Release pooled 7z decoder buffers across async and partial reads
...
Dispose cached folder decoders during async archive cleanup and scope temporary encoded-header decoders in both read paths. Release LZMA range-decoder input buffers on partial reads and failures while preserving borrowed source ownership.
Correct the synchronous extraction-reader benchmark and expand lifetime and checksum coverage. Document profiling showing async Archive allocations falling from 8.95 MiB to 0.70 MiB per extraction, with metadata-only allocations reduced by 70%.
Validation: 2,989 .NET 10 Release tests passed; all library targets, the performance project, and net48 test compilation succeeded. Formatting and whitespace checks passed.

Pool RAR Huffman scratch buffers and validate async checksums
...
Reuse unpacker-owned pooled scratch arrays for async RAR5 and RAR2 Huffman tables, preserving alphabet bounds and zeroed history tails. Match async Archive CRC32/BLAKE2sp verification to the synchronous path and dispose entry streams when initialization fails.
Add regression tests and profiling documentation showing approximately 3.13 MiB fewer managed allocations per 200 MiB extraction. Keep this change based directly on master without unrelated branch commits.
Validation: 2,983 .NET 10 Release tests passed, all six library targets built, net48 tests compiled, and formatting checks passed.
