Changes

Commits since v0.7.2

• fix(backend,bench): dispatch the fused W8A32 decode kernel on x86; bench opts into W8A8 (50b1f41)
• fix(compiler): reject a non-zero zero-point on the output-major path at compile time (e704f4a)
• perf(backend): block the output-major integer GEMVs at m > 1; correct the claim (5f9fc16)
• release: follow the deprecate-then-version-out lifecycle; bump to v0.8.0 (8ca84b6)
• fix(compiler): validate the OUTPUT_MAJOR declaration at compile time, not load (149a39a)
• perf(backend): pin + document the integer GEMV's m-scaling defect (5eccb0b)
• refactor(backend)+docs: typed wasm GEMV job; re-capture small-m benchmarks (19b163a)
• fix(compiler,exec): separate weight layout from W8A8 numerics; no silent-wrong (1588748)
• perf(backend): fix row-index-dependent bytes; reach wasm/NEON small-m; widen low-R GEMV (175bb15)
• perf(backend): batch the small-m remainder rows into one pass over B (6e9acec)
• refactor+docs: centralize decode gates, demote internals, correct stale claims (e907cc2)
• feat: weight-slot declaration — a weightless weight can reach the fast decode GEMV (14f591d)
• perf(backend): NEON e8cb kernel + wasm/NEON bulk widen; gate wasm dead code (1844e0d)
• feat(backend,compiler,archive): the codebook is model data, not engine data (7eb9876)
• refactor(backend,compiler): QuantTier registry — one row per weight encoding (0dd11fb)
• refactor(types,backend,compiler,exec): one canonical DTypeId; total accessors (96bd421)
• test(archive): freeze op_signature + wire bytes for legacy calls (κ guard) (8fe87d0)

What's Changed

• cleanup: parametric substrate — one dtype vocabulary, per-model codebooks, no silent-wrong (v0.8.0) by @afflom in #37
