Common boundaries
Feature gates and primitives that both codecs share.
| Specification | Scope |
|---|---|
| Codec features | Codec gates, shared types and isolated consumer checks. |
| No standard library | Alloc-backed APIs, feature precedence and compile-time SIMD. |
| Shared primitives | Common data, transforms, fixed boxed tables, the baseline SIMD level, prefetch and mask scans. |
| Uninitialized output | Write-only destinations for sessions and one-shot calls, and the C ABI’s use of them. |
