fix(helix): ndarray is a mandatory git dependency (codex P2 + "ndarray is mandatory")#463
Conversation
…ray is mandatory") Two converging directives: 1. codex P2 (#460): an optional `path` dependency does not make the default build self-contained — Cargo reads every dependency manifest (incl. optional) during resolution, so `ndarray = { path = "../../../ndarray", optional = true }` makes a clean checkout without the sibling fail before feature selection. The "default build needs no ndarray checkout" claim was false. 2. Directive: "ndarray is mandatory for lance-graph" (it is The Foundation). Fix: ndarray is now a mandatory, non-optional GIT dependency: ndarray = { git = "https://github.com/AdaWorldAPI/ndarray.git", branch = "master", default-features = false, features = ["std"] } - git source resolves the manifest remotely (no sibling checkout needed); - non-optional, so the `ndarray-hpc` feature is removed; - src/simd.rs is now single-impl (always ndarray::simd, no scalar fallback; ndarray does its own AVX-512/AVX2/scalar dispatch internally). No import cycle: helix is standalone (own [workspace] + root exclude) and the fork is self-contained (only internal subcrate path deps, no lance-graph back-dependency). [patch] is the wrong tool here (the workspace's [patch.crates-io] ndarray is separately ineffective: 0.17.2 can't satisfy the lance-index crates.io 0.16.1). Verified: 63 unit + 6 doctests green, clippy -D warnings + fmt clean (git source patched to the local master checkout for the in-sandbox build; github fetch is validated by CI). Board: PR_ARC #459 Correction + E-HELIX-NDARRAY-MANDATORY + LATEST_STATE + STATUS_BOARD D-HELIX-1. https://claude.ai/code/session_013rjF2Dvo1DnBACpbpYSffE

In the documented Cursor Cloud/setup-script environment, /ndarray is provided locally and no external services are required, but this mandatory git dependency now makes every cargo test --manifest-path crates/helix/Cargo.toml resolve by contacting GitHub before compilation. In a no-egress or proxy-blocked environment this fails during dependency resolution even when the local /ndarray checkout exists, so helix is no longer standalone-verifiable in the repo's supported setup; use a local path/patch fallback or other vendored/pinned source for that environment.

| **Correction (2026-06-03, follow-up PR after #460):** the `../../../ndarray` **path** dep + `ndarray-hpc` feature in the Added block above were wrong twice — (1) codex P2: an optional *path* dep still forces Cargo to read the local sibling manifest at resolution, so the "default build needs none of it" claim was false (a clean checkout failed before feature selection); (2) per the directive **"ndarray is mandatory for lance-graph,"** ndarray is not optional. Both fixed: ndarray is now a **mandatory, non-optional git dependency** (`git = AdaWorldAPI/ndarray @ master`, `ndarray-hpc` feature removed). `simd.rs` always uses `ndarray::simd` (no scalar-fallback variant).

Move this correction into a new prepended PR_ARC entry instead of editing #459.
This line mutates a historical section outside Confidence, which conflicts with the board immutability rule for PR_ARC_INVENTORY.md. Please prepend a new follow-up entry (e.g., PR #460/#463 correction record) and reference #459 there.

Resolve conflicting status evidence in D-HELIX-1 entry.
Line 15 currently mixes obsolete and current states in one live status cell (it says tests passed under --features ndarray-hpc, then later says ndarray-hpc was removed). Please keep only the current post-#460 status facts in this row to avoid governance drift.

…lict D-HELIX-1 status CodeRabbit flagged two board-governance issues on #463: - PR_ARC_INVENTORY.md edited the #459 historical section outside the Confidence field. Relocate the correction into a properly prepended #463 entry (rule-5: a separate-PR reversal gets its own entry) and reduce the #459 touch to a Confidence-line forward-pointer. - STATUS_BOARD.md D-HELIX-1 status mixed obsolete (zero-dep / 61 tests / --features ndarray-hpc) with current facts. Clean it to post-#463 reality only (mandatory git dep, no feature, 63 unit + 6 doctests). ndarray dependency source kept as git branch=master per user decision; the Codex P2 (offline) and CodeRabbit (pin-rev) threads are recorded as accepted trade-offs (wontfix) in the new #463 entry. https://claude.ai/code/session_013rjF2Dvo1DnBACpbpYSffE

Follow-up to #459/#460 — addresses the codex P2 on #460 ("ndarray is not clean") and the directive "ndarray is mandatory for lance-graph."
The problem (codex P2)
An optional
pathdependency does not make the default build self-contained: Cargo reads every dependency manifest — including optional ones — during resolution to build the lockfile. Sondarray = { path = "../../../ndarray", optional = true }makes a clean checkout without the sibling repo fail (failed to read .../ndarray/Cargo.toml) before feature selection. The merged "default build needs no ndarray checkout" claim (#460) was false.The fix
ndarray is now a mandatory, non-optional git dependency:
ndarray-hpcfeature is removed (per "ndarray is mandatory for lance-graph" — it is "The Foundation");src/simd.rsis now single-impl — alwaysndarray::simd(simd_ln_f32/F32x16/U8x64), no feature gate, no scalar-fallback variant to keep in sync (ndarray::simddoes its own AVX-512 / AVX2 / scalar dispatch internally).No import cycle (and why not
[patch])helix is standalone (own
[workspace]+ rootexclude), so it resolves ndarray independently of the lance-graph workspace's path-based ndarray — no source-unification needed.[patch]would be the wrong tool here: the workspace's own[patch.crates-io] ndarrayis separately known-ineffective (the fork's0.17.2can't semver-satisfy the lance-index crates.io0.16.1; rootCargo.tomlBLOCKED(D)). The fork is self-contained — only internal subcrate path deps (crates/p64,crates/fractal,ndarray-rand,crates/ndarray-gen) that travel with the clone — and has no back-dependency on lance-graph, so the git dep introduces no cycle.master== the commit helix was tested against (0129b5c), which exposessimd_ln_f32/U8x64/F32x16.Verification
