- Around line 18-19: Add CI coverage for the supervisor probe tests by updating
the Rust test workflow to run `cargo test --manifest-path
crates/lance-graph-supervisor/Cargo.toml --features supervisor`; the issue is
that the `w2b_real_owner_probe` tests are gated behind the `supervisor` feature
and currently never execute in CI, so add a dedicated job alongside the existing
`lance-graph`, `lance-graph-contract`, and `deepnsm` jobs to ensure the
`lance-graph-supervisor` crate’s probes are exercised.

…) — t1 measured Lane B: 32-byte-stride ;/\n scan via ndarray::simd::U8x32::cmpeq_mask (all SIMD from ndarray::simd per the workspace rule; probe pinned to x86-64-v3 so the ops are real AVX2 intrinsics), cross-block state carry, scalar parse kept. Lane D: actor-per-worker over Arc<Vec<u8>> via the AdaWorldAPI ractor fork (supervisor coordinates), identical chunking and commutative merge as lane C — only the worker primitive changes. Feature-gated (lane-b/lane-d); lanes A/C stay zero-dep (11/13/12/14 tests green across the four feature combos; clippy -D warnings clean, incl. the pre-existing gen.rs byte-grouping lint fixed here). t1 (recipe corpus rows=10000000 seed=42 sha256=f1853caa…5691 re-verified, 4 cores, best-of-2): A 7.012 / B 7.455 (1.06x vs A — delimiter find is not the bottleneck) / C 27.586 / D 22.078 Mrows/s (0.80x vs C — the 'ractor is a helper, not a messaging path' ruling as a measured ~20% actor tax incl. the forced corpus copy).

Lane R: byte-identical pipeline, slot = hash & 0xFFFF — F-R isolates the Morton addressing tax exactly, R-C prices flat-SoA-vs-BTreeMap. Both std-only; A/C zero-dep contract holds. Collision-forcing probe test (constant slot fn) included. t3 (recipe corpus re-verified, 4 cores, 5 passes, medians): C 28.3 / F 77.4 / R 86.3 Mrows/s; F/R single-thread 21.5/23.3 vs A 7.16. Readings: route-and-write beats look-up-and-compare 3x; the semantic address costs ~10% over plain radix at ~400-group cardinality (high-cardinality prefix-local payoff untested, unclaimed); the accumulator, not the scan, is where the win lives.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
No bounds guard against malformed/unterminated input.
parse_temp_tenths indexes bytes[0]/bytes[i] unconditionally, and lane_a_scalar's while data[i] != b';' { i += 1; } / while data[i] != b'\n' { i += 1; } scans have no i < len check. A corpus file passed to run <path> that lacks a trailing \n (or is otherwise malformed) will panic with an out-of-bounds index rather than failing with a clear message. lane_b_simd's tail loop (lane_b.rs) has the identical pattern, so a fix here should be mirrored there.
🛡️ Example: fail with a clear message instead of an opaque panic
while i < len {
let name_start = i;
- while data[i] != b';' {
+ while i < len && data[i] != b';' {
i += 1;
}
+ assert!(i < len, "corpus record at byte {name_start} is missing ';'");🤖 Prompt for AI Agents
