/**
|
|
* In-process embedder tests — ported from
|
|
* hive-mind/packages/core/src/mind/inprocess-embedder.test.ts.
|
|
*
|
|
* Memory Sync Repair Step 2. Source: hive-mind file at HEAD c363257.
|
|
*
|
|
* Verbatim port — only the import path is adjusted from
|
|
* `./inprocess-embedder.js` to `../../src/mind/inprocess-embedder.js`
|
|
* to match waggle-os's tests/mind/ placement convention. Both repos
|
|
* export the same `normalizeDimensions(input, target)` shape with the
|
|
* documented "no-copy fast path when dims match" contract.
