feat(wasm-sdk): chained document queries with js-evo-sdk facade and suite coverage - #4567
Conversation
Final PR of the chained-document-queries stack — the JS surface for
the provable semi-join:
- wasm-sdk: chained_document query module — typed
ChainedDocumentsQuery/ChainedDocumentsResult TS declarations,
getChainedDocuments / getChainedDocumentsWithProofInfo on WasmSdk.
The inner half reuses the documents query builder (where/orderBy in
the familiar shape); results come back as { innerDocuments,
outerDocuments } arrays in inner-proof order, always
proof-verified (two grovedb proofs bound to one quorum-signed root,
outer query re-derived from the proven inner values).
- js-evo-sdk: sdk.documents.chained / chainedWithProof facade methods
+ a README section ("posts I liked" with the pagination-cursor
recipe) next to the refersTo docs it builds on.
- platform-test-suite: chained-query case in IndexOnlyDocument.spec —
the registered yappr contract's like/post pair queried through the
shared EvoSDK (exported from createPlatformProofVerifier), asserting
both halves, order, and the base58 identifier surface.
wasm-sdk builds for wasm32 and the package bundles; js-evo-sdk
compiles against the regenerated types.

The JS surface's behavior is unchanged by the merged-proof rework (the verification lives below the FetchMany boundary), but its docs still described the two-proof envelope — align them. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

📝 WalkthroughWalkthroughAdds provable chained document query support to the WASM and JavaScript SDKs. The change includes query types, verified result handling, facade methods, documentation, and a functional test for joined documents. ChangesProvable chained document queries
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The chained-query implementation is otherwise mergeable, but the pagination example can produce an undefined cursor and inconsistent page ordering, which could mislead SDK users or yield incorrect pagination. This is a bounded documentation fix requiring owner awareness. Sequence Diagram(s)sequenceDiagram

Stop when the inner page is empty.
When innerDocuments is empty, cursor is undefined. The example then sends ['postId', '>', cursor]. Guard the next request with if (cursor !== undefined).

Use the same explicit order for every page.
The first query has no orderBy, but the next query adds ascending postId order. The cursor is valid only when both requests use the same order. Add orderBy: [['postId', 'asc']] to the first query and remove the “newest” claim, or use descending order with a matching < cursor.

Add a multi-document case to verify ordering.
These assertions cover only one inner and one outer document. They cannot detect reversed outerDocuments order. The contract in packages/rs-drive/src/query/drive_chained_document_query/mod.rs requires outer documents to follow the first appearance order from innerDocuments. Add a second joined document and assert both returned identifiers in the expected order.

Final PR of the chained-document-queries stack (reopens #4555, which GitHub auto-closed when its base branch merged as #4552 and was deleted before retargeting). The JS surface for the provable semi-join — "posts I liked" in one verified round trip from the browser.
