related() with a verb-type ARRAY returned edges for only the first type — the storage fast paths collapsed `verbType` (and, in their sibling blocks, `sourceId` and `targetId`) arrays to their first element, silently dropping the rest of the ask. Every consumer passing a verb list under-traversed with no error and no narration: the same quiet-loss class as the graph-first paging defect, one seam over. All four fast paths now union over the full requested set, deduped by edge id, before the metadata filters and pagination run. Pinned in tests/integration/related-verb-array.test.ts: the second requested type's edge returns in both array orders, on the anchor side, the target side, and the type-only path; a one-element array equals the scalar; no duplicates on overlap; pagination walks the union consistently.

|
|
* The storage fast paths for `sourceId + verbType` and `verbType` collapsed a
|
|
* verb-type ARRAY to its first element — `related({ from, type: [a, b] })`
|
|
* silently returned only `a` edges, whichever order the array came in. The

* same quiet-loss class as the graph-first paging defect, one seam over.
|
|
* These pins seed a store where the SECOND requested type's edge must come
|
|
* back, on every path the collapse lived in.
