The wire_vs_bast bench originated in alktty as the uncommitted curiosity probe that surfaced review #004's 400x read gap (the driver for the 0.3.0 compiled-forms release). It now lives here so alktype owns its perf story; the alktty-only async roundtrip group (tokio ChunkReader/ ChunkWriter over a duplex pipe) was dropped — that measures alktty's I/O stack, not this engine. The alktty copy is deleted. Groups: - read_chunk_stream / write_chunk_stream — the original ChunkHeader shape, byte-identical methodology, so numbers stay comparable with the historical series (400x → ~18x on read p64). - read_packet_stream (new) — SFTP-shaped byte-discriminator union (Read/Write variants, Write carries a length-prefixed bytes field): exercises CompositePlan::Union dispatch + variant walks + variable reads, the case ADR-011's framing argument was about. The alktype consumer pattern follows the documented FieldValue::Union contract; a pre-measurement parity check locks the pattern (variant walk size + disc size == packet size) so the stream loop can't drift silently. - validate_stream (new) — engine.validate_bytes per buffer (materialize + ValidationPlan walk), the read+validate-on-untrusted-stream shape alkcall cares about; closes the phase-7/8 bench deferral. - one-shots — engine_compile, sequential_reader_new, layout_build. criterion 0.7 dev-dep (default-features off). Benches don't affect the wasm gate (bench targets never compile under wasm32-unknown-unknown). Numbers (1024 chunks/iter, Xeon D-1521, shared box — ±10% noise): - read p64: hand 5.7 µs / alktype 104.8 µs (~18x; parity with the phase-2/8 record of 98-99 ns/chunk) - read p4k: hand 12.1 µs / alktype 107.5 µs - write p64: hand 14.0 µs / alktype 37.5 µs; p4k: 324/362 µs - packet read p64: hand 3.3 µs / alktype 622.6 µs (~189x — dominated by per-field String allocs + variant reader construction; the read_next (String, FieldValue) signature is pinned by the semver contract) - validate: header 458 ns/chunk, packet p64 2.23 µs, packet p4k 47 µs - one-shots: compile 615 µs (meta-schema dominated), reader_new 15.7 ns, layout_build 343 ns Verification: cargo test --release (566 tests green), clippy --all-targets -D warnings, wasm32-unknown-unknown build clean.
