   1. Guidance on PR #15219 (stats/base/ndarray/dcovarmtk): this is the first stats/base/ndarray addon taking five ndarrays; would like to confirm the addon.c structure before doing the same for scovarmtk and the ztest family.

   2. Guidance on PR #15222 (lapack/base/dlaln2, my first LAPACK routine): I've been working on this over the last few weeks, with some guidance from Pratik on the workflow, and used aayush's fixturegen - (https://github.com/aayush0325/fixturegen/blob/main/index.js) script to generate the stride/offset fixture variants (base fixtures come from Reference-LAPACK via a Fortran driver). Would appreciate feedback on the API conventions I chose: trans as a string for Fortran's LOGICAL LTRANS, and returning scale/xnorm via an out array with info as the return value (following dlassq).

   Approach for has-equal-values.

   The idea is to compare in word space instead of number space: 64-bit arrays are reinterpreted as interleaved high/low words, and the other operand is widened to the same two-word form. The 64-bit side is never cast to a double, so nothing rounds above 2^53.

   Three cases:

   1. Same dtype (uint64/uint64, int64/int64): compare words directly with internal.
   2. Uint64Array vs Int64Array: both words must match and the signed high word's sign bit must be unset, since identical bits mean different numbers once the signed value is negative (-1 vs 2^64-1).
   3. 64-bit vs everything else: reject the element unless it is an integer within the 64-bit dtype's range, then split it into high/low words and compare. This one kernel covers all the narrower integer arrays and the float arrays: 1.5, NaN, and out-of-range values fail the first check, and integer-valued floats split exactly, so Float64Array matches a Uint64Array up to 2^53.

   Dispatch checks x then y for each 64-bit type, so argument order doesn't matter, and indices.js resolves word order from endianness rather than assuming low word first.

   I updated stdlib#15106 (stdlib-js/stdlib#15106) based on last week’s feedback. I moved the Highway code into a separate C++ file and removed the custom manifest defines. Could we take another look at the PR?

   I’ve cleaned up the following PRs and they’re now ready for review and merge

   • feat: add stats/base/ndarray/dnanstdevyc
   • feat: add stats/base/ndarray/dnanstdevwd
   • feat: add stats/base/ndarray/dnanstdevtk
   • feat: add stats/base/ndarray/nanstdev

   Also, I wanted to get your thoughts on feat: add stats/strided/median. If we can get this merged, I can move forward with the next set of median packages.
