docs(matrix): TypeScript envelope pre-scan and aarch64 AES probe ship in npm 0.2.2 (LAB-10705) - #233
@cachekit-io/cachekit 0.2.2 (npm, 2026-10-28) is the first release that pins cachekit-core-ts 0.2.1 and cachekit-core-wasm 0.2.1, both exact. All five platform .node binaries of cachekit-core-ts 0.2.1 and the cachekit-core-wasm 0.2.1 .wasm embed cachekit-core 0.7.2, and each carries the decode pre-scan error text (strings, 2026-11-07). 0.2.3, the current latest, keeps the same pins. The matrix still described npm 0.2.1, whose 0.2.0 bindings embed core 0.6.0, so it marked shipped TypeScript behaviour as unreleased.
What changes in sdk-feature-matrix.md:
Wire format (ByteStorage), TypeScript cell: the envelope pre-scan exception is closed from 0.2.2, and the "🚧 unreleased — compliant on main" clause is gone. The cell stays ⚠️, because the allocation bound for the size-cap and ratio vectors is still unasserted in cachekit-ts (test/fixtures/wire-vectors.ts defers it). The last clause now says that instead of "both 0.2.1 bindings embed 0.6.0".
Test vectors in CI, TypeScript cell: the decode-bounds.json run through both unpack bindings (cachekit-ts#245) reads ✅ since npm 0.2.2. That PR is in the cachekit-v0.2.2 tag's history and not in cachekit-v0.2.1's. At the 0.2.2 tag, test (22), test (24) and the Workers lane pass.
Hardware acceleration detection, TypeScript cell, and note ⁶: 0.2.2+ probes the Armv8 Crypto Extension on aarch64 (is_aarch64_feature_detected!("aes") at the cachekit-core-v0.7.2 tag), and 0.2.1 reports true on every aarch64 build. The forecast sentence that waited for this release is removed.
The header's "Last updated" line now names this flip, because its previous sentence ended "so the TypeScript caveats that wait on core 0.7.0 stay", which is no longer true.
The core-version table under Rust Core is unchanged. It records each SDK's bin writer rollout (py 0.17.1, rs 0.6.0, ts 0.1.5 and 0.2.1), not each SDK's current core, and its 0.2.1 rows stay true.
The 0.2.2 README's "Is AES hardware-accelerated on this host?" paragraph already describes the aarch64 probe and has no NEON or "every aarch64" text, so no SDK README change is needed.
Checks: tools/check-version-floors.py, tools/test_changelog_collect.py and tools/conformance.py check --base HEAD^1 pass.
… in npm 0.2.2
@cachekit-io/cachekit 0.2.2 is the first release that pins cachekit-core-ts
0.2.1 and cachekit-core-wasm 0.2.1, whose binaries embed cachekit-core 0.7.2.
Flip the TypeScript Wire format, Test vectors and Hardware acceleration cells
and note 6 from unreleased to released at that floor. The Wire format cell keeps
its allocation-bound caveat: cachekit-ts still does not assert it.
Added release notes and updated the feature matrix for version 0.2.2, covering hardware-acceleration detection, input validation and test coverage.
Walkthrough
The changelog and feature matrix now document npm 0.2.2, including its embedded core version, ByteStorage envelope pre-scan, decode-bounds vector coverage, allocation-bound status, and aarch64 hardware-acceleration detection.

The release notes and matrix record the embedded cachekit-core 0.7.2 version, envelope pre-scan, decode-bounds vector coverage through both unpack bindings, and aarch64 Crypto Extension detection. They also state that the allocation-bound assertion remains absent from cachekit-ts tests.

cachekit-io/protocol#203: Documents the TypeScript envelope pre-scan and decode-bounds.json coverage before their release in npm 0.2.2.
cachekit-io/protocol#207: Documents the Python release status of the ByteStorage envelope pre-scan supplied by cachekit-core.

Merge Risk: Low · previous review 1978c
This documentation update may overstate TypeScript wire-format compliance, because CI does not test the exact wasm artifact that is distributed. No runtime behavior changes. Adjust the matrix wording before merge, or accept the caveat.
