feat: expose protocol v14 ranked queries and document references to JavaScript

[QuantumExplorer]

Issue being fixed or feature implemented

Closes #4402.

Protocol v14 shipped two client-visible features that stopped at the Rust SDK:

• Ranked aggregate indexes / provable top-K queries (feat: ranked aggregate indexes with provable top-K queries (protocol v14) #4266, feat(drive): boolean HAVING range queries on ranked index axes #4384, feat(drive): per-prefix ranked aggregates on compound indexes #4393)
• Document references, refersTo (feat(platform)!: reference validation for documents (refersTo) #2993, feat(platform)!: permanent document references (refersTo permanentDocument) #4390, feat(platform)!: identity public key references (refersTo identityPublicKey) #4397)

Neither had a JavaScript surface. js-evo-sdk had exactly one change between v4.1.0 and v4.2-dev — a version bump — because the gap starts a layer down, in wasm-sdk / wasm-dpp2.

What was done?

Ranked and having-range queries — wasm-sdk, js-evo-sdk

getDocumentsRanked / getDocumentsHaving plus their WithProofInfo twins, wrapped as documents.ranked() / documents.having() in evo-sdk. Both modes are bound together because they ride the same wire path and share a result type.

The grammar is not reimplemented. detect_ranked_mode / detect_having_mode are pub under rs-drive's verify feature — which wasm-sdk already enables — and are pure and contract-free. The binding calls them directly, so a malformed query fails locally with rs-drive's own message and cannot drift from what the server's query table and the proof verifier enforce. (rs-sdk's assert_ranked_shape was deliberately not widened: it phrases errors in terms of Rust builder methods, which is the wrong vocabulary for a JS caller.)

Design decisions worth a reviewer's attention:

• Dedicated DocumentsRankedQuery / DocumentsHavingQuery rather than adding offset to DocumentsQuery, which feeds four entry points that reject an offset. The dedicated interfaces also make limit and groupBy non-optional, which ranked requires.
• direction: 'asc' | 'desc' replaces orderBy. This keeps the $count sentinel out of the public surface entirely, and structurally prevents the ordering trap documented at document_query.rs:330 — the parser owns the with_select-before-order_by_selected_aggregate sequence, so a caller cannot invert it.
• Results are objects, not Maps. startingRank has nowhere to live in a Map, and without it { limit: 1, offset: 4 } — "the 5th best" — has no meaning. Entry order is the answer, which a Map only conveys implicitly.
• Entries carry both groupKeyHex and a decoded groupValue. Hex correlates with the count/sum/average maps for the same grouping; the decode (via DocumentType::deserialize_value_for_key) is what makes a ranking actually name its groups, since index-key decoding is type-directed and not reimplementable in JS. Decoding is best effort — an undecodable key yields undefined and never fails the query; an empty key is null, the write path's marker for an absent optional value.
• Averages return exact fixed point plus the scale, rather than pre-divided. Pre-dividing destroys the integer the proof commits to, and the scale is a build-time constant that has already moved by four orders of magnitude, so it is returned rather than documented.
• deny_unknown_fields on the query inputs, a deliberate departure from DocumentsQueryInput. The expected mistake is pasting a DocumentsQuery into a ranked call and dragging orderBy along; permissive serde would drop it and still run the query under the default direction, answering a different question silently.

Contract-level checks (does the index declare rankedCountable / rankedSummable / rankedAverageable, do the pins cover a compound index's leading properties) are left to the network on purpose: wasm-sdk serves contracts from a cache, so a stale entry would reject queries the network would happily serve. Shape validation reads no contract and has no such hazard.

Prefix IN pins — follow-up to #4401

#4401 landed after this branch was written and widened the grammar the binding delegates to: a compound index's leading property may now be pinned with a bounded IN rather than ==, entries merged from several branches carry the branch they came from, and a non-zero OFFSET is rejected alongside a branching IN.

The Rust side needed nothing. Because the binding hands where clauses to detect_ranked_mode instead of re-implementing the operator grammar, an IN pin already flowed through end to end the moment #4401 merged — which is the payoff the delegation was chosen for. What was stale was the JS-facing layer wrapped around it:

• DocumentsIndexPin structurally forbade in, so a shipped capability was unreachable from TypeScript without a cast, and its doc comment explained in as something that would need one secondary walk per element — now a description of what the server does rather than why it refuses.
• RankedEntry.in_key was dropped on the floor. A merged page can carry one group key twice, once per pinned prefix, so without the discriminator those two rows are indistinguishable. It surfaces as branchKeyHex, set only on a merged page — absent, not undefined-valued, on a single-prefix page, so 'branchKeyHex' in entry reads as "this page is a merge".
• Nothing named MAX_PREFIX_IN_BRANCHES, so a caller discovered the fan-out ceiling by being rejected. It joins maxRankedLimit as a static on WasmSdk and EvoSDK.
• The offset docs still promised the skip had no ceiling and no caveats.

deny_unknown_fields keeps doing its job here: timeRange (#3740) is not added to the ranked input, because the ranked dispatcher rejects a time-range selection outright — a document belongs to every bucket containing its timestamp, so it would rank into several groups at once. The omission is the correct surface, and a pasted timeRange now fails locally rather than at the node.

Document references — wasm-dpp2

DataContract.documentTypeReferences(name) and .documentReferences report what a contract's refersTo declarations point at, with a DocumentPropertyReference TypeScript union mirroring DocumentPropertyReferenceTarget.

This lives in wasm-dpp2 rather than wasm-sdk because it is parsed-contract metadata — no network, no Sdk handle, no async — and pub use wasm_dpp2::* carries it to wasm-sdk and evo-sdk with no changes in either. No DocumentType wrapper class was added: DocumentTypeRef<'_> cannot cross wasm-bindgen, so one would mean cloning the index map and schema on every access, and it is a ~20-accessor API commitment that deserves its own design pass.

Two details that mirror consensus exactly:

• It walks flattened_properties() (dotted paths), which is what both the registration-time and write-time validators walk, and how they build their error path. The nested map would produce paths no consensus error matches and would miss nested declarations.
• An omitted contractId resolves to the declaring contract's own id, because consensus computes contract_id.unwrap_or(contract.id()) and treats an explicit self-id identically. ref.contractId.equals(contract.id) is the self-reference test, with no null branch.

refersTo is only parsed from protocol version 14 onward, so a contract deserialized against an earlier version reports none. That is faithful to what consensus enforced at that version, and it is documented as a trap, since toJSON() still shows the raw keyword.

On the consensus errors: the codes already reach JS. I traced the full path and confirmed wasm-sdk/src/error.rs passes Some(err.code as i32) through on the broadcast path, so e.code === 40123 works today. This PR only names them — a DocumentReferenceErrorCode enum (40120-40125) and a ConsensusError.code getter — so callers can branch without a message regex.

An exhaustive match guard test in rs-dpp makes adding a sixth reference target a compile error in the crate that owns the enum, where whoever adds it will see that the JS mirror needs updating.

How Has This Been Tested?

Offline only — no functional tests against a running node, since ranked/having need a PV14 network.

• 32 Rust unit tests in document_ranked.rs covering the builder shape (the with_select ordering regression, the $count sentinel, direction defaults, offset, limit ceilings asserted against MAX_RANKED_LIMIT / MAX_HAVING_LIMIT rather than literals), the having grammar (derived aggregate, two-operand between, rejected non-contiguous operators, optional ordering), the index pins (equality, null, rejected range and repeated pins), the serde surface (orderBy / cursors / offset rejected rather than dropped), and result shaping (hex convention, string decode, absent vs. undecodable keys, the avg scale).
• 13 wasm-dpp2 specs, including a pre-v14 gate regression asserting the accessor reports nothing while the raw schema still carries the keyword.
• 6 stubbed evo-sdk facade specs and 2 wasm-sdk specs pinning the pub use wasm_dpp2::* fan-out.

Full suites and lints, all exit 0:

• cargo fmt --check --all; cargo clippy -p dpp -p wasm-dpp2 -p wasm-sdk --all-targets --all-features -D warnings; cargo test for all three; cargo check -p wasm-sdk --target wasm32-unknown-unknown
• wasm-dpp2 1155 tests, wasm-sdk 400, evo-sdk 219 (mocha + karma); all three package lints clean

I also verified in the generated .d.ts that every new type emits properly rather than falling back to any.

Rebased onto current v4.2-dev and re-verified end to end — first after #4388 restructured rs-sdk/src/platform/documents/, and again after #4401, #3740 and #4486 landed. The second rebase is the one that mattered: #4401 added a third field to RankedEntry, which broke four struct literals in the host tests (E0063), and a fifth in the wasm32-gated module that no host-target build compiles. This branch's own green CI run predates all of it.

New coverage for the IN surface: 8 host tests (the pin is carried intact, the branch ceiling asserted against MAX_PREFIX_IN_BRANCHES rather than a literal, two branching INs rejected, OFFSET × branching IN rejected, and — so that exclusion cannot pass while being over-broad — a singleton IN plus OFFSET accepted), 3 host tests on the branch-key decode, 2 wasm32 tests pinning absent-vs-empty-string at the real JS boundary, and 1 evo-sdk spec on the new static.

Each new assertion was mutation-checked rather than assumed: forcing branch_key_hex: None fails exactly the tests that assert it, and emitting the field as undefined instead of omitting it fails the boundary test alone — which is the distinction the host target cannot see.

Breaking Changes

None. Everything here is additive: new query entry points, new accessors on DataContract, and a new error-code enum. No existing signature or wire shape changes.

Notes for reviewers

Two adjacent gaps I found while tracing the error path and deliberately left out of scope:

1. WasmSdkError drops StateTransitionBroadcastError.cause: Option<ConsensusError>, so the structured consensus fields (path, entityId, keyId) are message text only. Carrying the serialized bytes as consensusErrorBytes would let JS use the existing ConsensusError.deserialize to read them. That is structured detail rather than branchability, which is what this PR set out to deliver.
2. The check_tx rejection path collapses consensus errors to Error::Protocol with code: -1, erasing the code. Document transitions cannot take that path (full state validation is gated behind validates_full_state_on_check_tx(), false for everything but masternode vote), but other transitions can.

One convention note: document_type_reference.rs uses js_sys::Reflect::set. CONVENTIONS.md forbids that for conversion shapes (toObject / toJSON, where the rs-dpp serde derive is the source of truth); this is a getter assembling a collection, matching DataContract::tokens and ::groups.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: ⚪ Minimal · up to 1cca8

The change is otherwise merge-ready, with only a localized TypeScript documentation example needing error-variable narrowing before reading its code; this is a minor follow-up and not a merge-blocking runtime risk.

Final validation — Codex/Sol only (Phase 2 disabled)

The ranked-query bindings correctly reuse Drive's versioned grammar and proof-verifying SDK fetch paths, but two JavaScript-facing issues remain: valid large integer group keys can reject an entire result, and the evo-sdk README names a helper that the EvoSDK class does not expose. Source: codex-general, codex-ffi-engineer, and codex-rust-quality reviewers; Claude final verifier.

Validated zero-blocker Codex/Sol precheck evidence was promoted to final because Phase 2 (Sonnet/Opus) is temporarily disabled. This is Codex/Sol-only final validation, not Codex + Sonnet/Opus coverage.

- [SUGGESTION] packages/wasm-sdk/src/queries/document_ranked.rs:886-892: Large integer group keys reject valid results at the WASM boundary
  `deserialize_value_for_key` can legitimately return `Value::I64`, `Value::U64`, `Value::I128`, or `Value::U128` for indexed group-by properties. This conversion first passes those values through `serde_json`; the subsequent JSON-compatible serde-wasm-bindgen serializer rejects 64-bit values outside JavaScript's safe-integer range, while values outside serde_json's 64-bit number domain fail even earlier. A valid verified result can therefore reject the entire Promise instead of returning the documented lossless `groupKeyHex` fallback. Fall back to the non-human-readable object conversion, which emits exact JavaScript `BigInt` values, and add a WASM-runtime regression test with a group key above `Number.MAX_SAFE_INTEGER` so the actual exported result path is exercised.

In `packages/js-evo-sdk/README.md`:
- [SUGGESTION] packages/js-evo-sdk/README.md:120: README points to a nonexistent EvoSDK method
  The README directs callers to `EvoSDK.maxRankedLimit()`, but `maxRankedLimit()` is generated only as a static method on the exported `WasmSdk` class. The `EvoSDK` facade forwards `setLogLevel` and `getLatestVersionNumber`, but does not define this helper, so the documented invocation fails type checking and produces a runtime TypeError. Document `WasmSdk.maxRankedLimit()` instead, or add an initialization-aware forwarding method to `EvoSDK` if that is the intended public API.

Addressed the CodeRabbit nitpick from review 4999731747 in d50a2f6: Ranked queries and Document references (refersTo) are now listed in the evo-sdk README table of contents. Used the file's existing plain-link style rather than the suggested diff, whose link targets had backticks inside the parentheses and would not have rendered as links. Verified every TOC entry resolves to a real heading anchor and that none dangle.

This nitpick had no inline thread (the review carries no inline comments), so there was nothing to reply to or resolve inline.

The current head fixes both prior JavaScript-facing findings: wide integer group keys now cross as exact BigInts, and the documented EvoSDK ranked helpers now exist. One in-scope suggestion remains because the regression helper is exported through the production WASM and TypeScript API despite being documented as test-only.

  `test_ranked_group_value` is compiled unconditionally with `#[wasm_bindgen]`, so wasm-bindgen includes `testRankedGroupValue` in the production JavaScript bundle and generated TypeScript declarations. The wasm-sdk bundle re-exports every generated symbol, and js-evo-sdk subsequently re-exports that WASM surface, so the comment saying this is unsupported does not keep consumers from discovering and depending on it. Exercise `group_value_to_js` with a `wasm-bindgen-test`, or gate this export behind a non-default testing feature that the test build explicitly enables.

The implementation is sound and the prior production WASM test-helper export is fixed, with no blocking issues found. Two in-scope test-coverage suggestions remain: wide-integer exactness is no longer exercised at the JavaScript boundary, and the WASM error-code test does not compare its mappings with DPP's canonical codes.

- [SUGGESTION] packages/wasm-sdk/src/queries/document_ranked.rs:940-946: Wide-integer regression no longer exercises the WASM boundary
  The host tests verify only that wide `Value` variants select `ExactBigInt`; they cannot execute `exact_integer_to_js` because `js_sys` panics off-wasm. Returning `JsValue` makes this path infallible, but it does not guarantee exactness or the required JavaScript `bigint` representation—a future `JsValue::from_f64(inner as f64)` implementation would still satisfy the signature and pass every current test while corrupting group keys. Add a private `wasm-bindgen-test`, or equivalent production-path WASM test, that renders signed and unsigned values above `Number.MAX_SAFE_INTEGER` and asserts both their JavaScript type and exact value without exporting a test-only production API.

In `packages/wasm-dpp2/src/consensus_error.rs`:
- [SUGGESTION] packages/wasm-dpp2/src/consensus_error.rs:109-143: Error-code test validates duplicated literals rather than DPP codes
  This test compares the WASM enum and `from_code` with the same numeric literals duplicated in their implementations. It therefore still passes if a JavaScript name is consistently assigned the wrong protocol code, such as two names being swapped. Construct each corresponding DPP reference-error variant, obtain its canonical code through `ErrorWithCode`, and assert that it maps to the intended `DocumentReferenceErrorCodeWasm` variant; this directly verifies the advertised correspondence with DPP's source of truth.

Final validation — Codex/Sol only (Phase 2 disabled)

Both prior test-coverage findings are fixed at the exact head, and the targeted consensus-error and wasm32 boundary tests pass. One in-scope suggestion remains: the new ranked and having query inputs cannot represent valid 128-bit equality pins because those operands are routed through serde_json::Value and a BigInt deserialization path limited to 64-bit values.

In `packages/wasm-sdk/src/queries/document_ranked.rs`:
- [SUGGESTION] packages/wasm-sdk/src/queries/document_ranked.rs:448-449: Wide 128-bit equality pins cannot cross the query boundary
  The ranked and having inputs store each `where` clause as `serde_json::Value`, and `deserialize_required_query` routes the JavaScript object through `from_object` and `platform_value_from_object`. The configured serde-wasm-bindgen deserializer handles `deserialize_any` BigInts only within `i64::MIN..=u64::MAX`, while `serde_json::Value` cannot retain integers outside its 64-bit number domain. A JavaScript BigInt representing a valid `u128` value above `u64::MAX` or an `i128` value below `i64::MIN` is therefore rejected before `parse_where_clause` runs. DPP supports `U128` and `I128` indexed properties, and Drive's `encode_equality_prefix_values` serializes their equality pins, so valid compound ranked and having indexes are unreachable through these bindings. Preserve pin operands as `platform_value::Value` through deserialization using a conversion that supports 128-bit BigInts, and add wasm32 boundary tests for both sides of the 64-bit range.

Final validation — Codex/Sol only (Phase 2 disabled)

The reviewed JavaScript surfaces preserve the SDK proof-verification path and reuse Drive’s versioned ranked/having query grammar; no in-scope correctness, security, or architectural defects remain. The prior 128-bit equality-pin finding is outdated because network contracts serialize raw schemas and reparse integer properties through an i64-bounded classifier that can produce at most U64 or I64, so no valid current index can require a wider pin.

Final validation — Codex/Sol only (Phase 2 disabled)

The implementation preserves the SDK proof-verification path and delegates ranked and having grammar validation to Drive, with no blocking correctness or architectural issues found. Three JavaScript-facing documentation and diagnostic suggestions remain: two descriptions do not fully reflect the newly exposed prefix in grammar, and one strict-TypeScript README example accesses an unknown catch value without narrowing it.
