Preliminary review — Codex only
The shared decoders and extracted builders largely preserve the existing behavior, but the new request-driven document verifier does not bind verification to every semantically relevant request field. A malicious transport can therefore substitute a valid proof for a different query, so this trust-boundary issue must be fixed before merging.

- [BLOCKING] packages/dash-platform-queries/src/documents/document_query.rs:665-678: Reject request fields that are discarded before proof verification
Validating only the `select` projection does not ensure that the proof corresponds to the wire request. The subsequent `TryFrom<&DocumentQuery> for DriveDocumentQuery` conversion discards `group_by` and `having`, even though the server rejects both for `SELECT DOCUMENTS`; consequently, an untrusted transport can pair a request such as `SELECT DOCUMENTS GROUP BY age` with a valid proof for the corresponding plain document query and this function will accept it. The conversion also narrows `request.limit` with `as u16` at lines 1127-1129, so a wire limit of 65537 becomes 1 even though the server rejects limits above `u16::MAX`. Plain-document `offset` and a false `prove` flag are additional request shapes that cannot produce this proved response from the real server but are not rejected here. GroveDB and Tenderdash proofs authenticate the state and resolved Drive query, not the discarded request envelope. Before delegating, reject every field incompatible with a proved plain-document request (`group_by`, `having`, `offset`, and `prove == false`) and use a checked `u16::try_from` conversion for the limit so no request information is silently changed.

Preliminary review — Codex only
The shared proto conversions and extracted document builders generally preserve existing behavior and add useful deterministic coverage. However, the request-driven verifier still reduces the wire request to a narrower Drive query without validating every field that the server uses for routing, allowing a fabricated response to verify against a request the server would reject.

(existing thread: https://github.com/dashpay/platform/pull/4389#discussion_r3771773859)
Checking only that `select` is the documents projection does not bind verification to the complete wire request. The subsequent `TryFrom<&DocumentQuery> for DriveDocumentQuery` conversion discards `group_by` and `having`, although the server rejects both when used with `SELECT DOCUMENTS`. It also narrows a nonzero `u32` limit with `as u16`, so a request for 65537 documents is verified as a limit-1 query even though the server rejects limits above `u16::MAX`. A plain-document `offset` is lowered into a Drive query despite being rejected by the server's routing layer, and `prove == false` is ignored even though an honest server cannot return this proved response for such a request. Consequently, an untrusted transport can pair one of these server-invalid requests with a valid proof for the reduced Drive query and this function accepts it. Before delegating, reject nonempty `group_by` or `having`, any plain-document `offset`, and `prove == false`, and convert the limit with `u16::try_from` so no request information is silently changed.

Preliminary review — Codex only
The prior request-envelope binding issue is fixed: discarded fields are now rejected before proof verification, and limit narrowing is checked. Two server-parity gaps remain in the new request-driven verifier: it accepts wire versions disabled by the supplied PlatformVersion and explicit document limits above the server's canonical cap, allowing proofs to authenticate request/response pairings that an honest server could not produce.

In `packages/dash-platform-queries/src/documents/document_query.rs`:
- [BLOCKING] packages/dash-platform-queries/src/documents/document_query.rs:761-767: Reject document wire versions unavailable at the target platform version
The verifier dispatches on the request oneof without checking whether that wire version is enabled by `platform_version.drive_abci.query.document_query`. The server performs this check in `rs-drive-abci/src/query/document_query/mod.rs` before decoding or executing the request. For example, PlatformVersions 1–11 have bounds `min_version = 0, max_version = 0`, so their servers reject every V1 request with `UnsupportedQueryVersion`; this verifier instead decodes the V1 request and can verify a genuine V0 proof for the equivalent lowered `DriveDocumentQuery`. An untrusted transport can therefore attach a valid proof to a request that an honest server at the supplied PlatformVersion could not have answered. Derive the request feature version (`V0 = 0`, `V1 = 1`) and reject it unless the supplied version bounds accept it before decoding or delegating to `FromProof`.
- [BLOCKING] packages/dash-platform-queries/src/documents/document_query.rs:1234-1245: Enforce the server's document limit cap during verification
The checked `u16` conversion prevents wrapping, but it still accepts explicit limits from 101 through 65535. The server passes the converted value to `DriveDocumentQuery::from_typed_clauses`, which rejects any value above `DriveConfig::default().default_query_limit` (`DEFAULT_QUERY_LIMIT`, currently 100). The verifier bypasses that constructor and creates a raw `DriveDocumentQuery` with values such as `limit = Some(101)`. If the matching range contains fewer documents than either limit, a genuine proof for a server-valid query can also satisfy the larger path query, so verification accepts a fabricated request/response pairing that an honest server would reject. Validate explicit plain-document limits against the same canonical limit used by proof verification, rather than only checking whether they fit in `u16`.

Final validation — Codex/Sol only (Phase 2 disabled)
The two prior trust-boundary blockers are fixed: document verification now rejects unsupported wire versions before decoding or provider access, and plain-document limits above the canonical server cap are rejected before proof verification. No blocking issue remains, but the new embedder API needs security guidance, the shared decoder exposes unnecessary implementation details, and the aggregate-limit hardening needs stronger boundary coverage. Tests could not be rerun because cargo is unavailable in this environment.

- [SUGGESTION] packages/dash-platform-queries/src/dpns_usernames.rs:29-34: Document the DPNS salt secrecy and reveal-order requirements
This new transport-free builder intentionally delegates randomness and submission ordering to its caller, but its public contract only says that the caller supplies a salt. The existing networked SDK generates a fresh salt from `StdRng::from_entropy()` and waits for the preorder response before submitting the domain document. Embedders need the same security requirements: a predictable or reused salt allows observers to dictionary-test likely labels against `sha256d(salt || normalized_label || ".dash")`, while publishing the domain document before preorder confirmation reveals the commitment preimage early. Document that every registration requires a fresh CSPRNG-generated salt and that the salt, label, and domain document must remain private until the preorder is confirmed.

- [SUGGESTION] packages/dash-platform-queries/src/documents/proto_conversions.rs:75-298: Keep internal proto conversion primitives out of the public API
The extraction widened `where_operator_from_proto`, `value_from_proto`, `where_clause_from_proto`, `order_clause_from_proto`, and `having_clause_from_proto` from the old server module's `pub(super)` visibility to public crate API. Repository-wide callers only use these singular helpers inside this module; cross-crate consumers require `DecodeError`, the three plural request-level decoders, and `select_from_proto`. Every unnecessary `pub` function becomes downstream semver surface and constrains future changes to depth limits, validation, and error classification. Keep the singular helpers private while retaining public visibility for the actual cross-crate facade.

- [SUGGESTION] packages/dash-platform-queries/tests/document_query_wire_roundtrip.rs:576-609: Exercise all aggregate limit paths and sentinel translations
The new aggregate-cap test invokes only `DocumentCount`, and every case exits from `check_within_server_cap` before either centralized walk conversion runs. The current implementation correctly calls the gate from COUNT, SUM, and AVG, but this test would not catch a future omission from the SUM or AVG entry point, nor would it catch swapping the proof-sensitive sentinel translations (`0` to `DEFAULT_QUERY_LIMIT` for distinct walks and `0` to `None` for carrier walks). Add direct boundary coverage for `0`, `1`, `DEFAULT_MAX_QUERY_LIMIT`, and cap-plus-one, and exercise the over-cap rejection through `DocumentCount`, `DocumentSum`, and `DocumentAverage`.

Preliminary review — Codex only
The shared decoders and extracted builders preserve the intended ownership boundaries, and all three prior suggestions are fixed at the exact head. Two in-scope proof-binding defects remain: omitted plain-document limits are reconstructed as unbounded queries, and COUNT range-outer carrier proofs use the wrong default and cap; both can make verification diverge from the server. Tests could not be rerun because cargo is unavailable in this environment.

In `packages/dash-platform-queries/src/documents/aggregate_limit.rs`:
- [BLOCKING] packages/dash-platform-queries/src/documents/aggregate_limit.rs:76-87: Preserve the range-outer carrier limit during COUNT verification
`carrier_walk_limit` treats every carrier proof as the In-outer shape, but COUNT also uses `RangeAggregateCarrierProof` for the G8 range-outer shape: `GROUP BY` one range field with two range clauses on distinct fields. `DriveDocumentCountQuery::detect_mode_versioned` routes that query to the carrier mode, while the server converts an omitted limit to `Some(MAX_CARRIER_AGGREGATE_OUTER_RANGE_LIMIT)` (currently 10). The verifier passes `None` from `count_proof_helpers.rs:280`, so `verify_carrier_aggregate_count_proof` reconstructs a different proof-sensitive `SizedQuery::limit` and rejects an honest server proof. The shared 100-item cap also permits explicit G8 limits from 11 through 100 even though the server rejects them above the carrier-specific cap of 10. Make COUNT carrier translation shape-aware: range-outer queries must use the compile-time range-outer default for limit 0 and enforce that carrier-specific cap, while In-outer queries retain `None` for an omitted limit.
- [SUGGESTION] packages/dash-platform-queries/src/documents/aggregate_limit.rs:45-87: Encode aggregate-limit validation in the returned type
`check_within_server_cap` returns `()`, while `distinct_walk_limit` and `carrier_walk_limit` independently accept the original `u32` and narrow it with `as u16`. Every current COUNT, SUM, and AVG caller runs the check first, but Rust does not encode that ordering invariant, and the `debug_assert!` disappears from release builds. A future internal caller that skips the separate gate can therefore truncate an over-wide value and reconstruct the wrong proof query. Return a private validated-limit newtype whose methods perform the walk-specific conversions, or make each conversion validate and return `Result`; callers can still create the validated value at function entry to preserve pre-provider rejection ordering.

Nothing subsequently applies the server default: `DriveDocumentQuery::construct_path_query` forwards this field directly into `SizedQuery`, where `None` is unbounded. The server instead maps V0 `limit = 0` and V1 `limit = None` to `Some(self.config.drive.default_query_limit)` before calling `from_typed_clauses`, which stores the concrete limit. Under the canonical configuration, an honest request therefore proves at most 100 documents while this verifier accepts an authenticated proof for every matching document. A malicious full node can exploit that mismatch to return more documents than the request could legitimately produce and control excess proof processing.

🔴 Blocking: Preserve the range-outer carrier limit during COUNT verification
carrier_walk_limit treats every carrier proof as the In-outer shape, but COUNT also uses RangeAggregateCarrierProof for the G8 range-outer shape: GROUP BY one range field with two range clauses on distinct fields. DriveDocumentCountQuery::detect_mode_versioned routes that query to the carrier mode, while the server converts an omitted limit to Some(MAX_CARRIER_AGGREGATE_OUTER_RANGE_LIMIT) (currently 10). The verifier passes None from count_proof_helpers.rs:280, so verify_carrier_aggregate_count_proof reconstructs a different proof-sensitive SizedQuery::limit and rejects an honest server proof. The shared 100-item cap also permits explicit G8 limits from 11 through 100 even though the server rejects them above the carrier-specific cap of 10. Make COUNT carrier translation shape-aware: range-outer queries must use the compile-time range-outer default for limit 0 and enforce that carrier-specific cap, while In-outer queries retain None for an omitted limit.

Fixed in b6ea184. The COUNT carrier translation now mirrors the dispatcher's own shape test (two range operators among the where clauses): range-outer (G8) lowers an unset limit to MAX_CARRIER_AGGREGATE_OUTER_RANGE_LIMIT and refuses explicit limits above that cap; In-outer (G7) keeps None and — matching the server exactly — refuses every explicit limit, which the finding's last sentence didn't require but the dispatcher does. Unit tests cover both shapes at their boundaries.

🟡 Suggestion: Encode aggregate-limit validation in the returned type
check_within_server_cap returns (), while distinct_walk_limit and carrier_walk_limit independently accept the original u32 and narrow it with as u16. Every current COUNT, SUM, and AVG caller runs the check first, but Rust does not encode that ordering invariant, and the debug_assert! disappears from release builds. A future internal caller that skips the separate gate can therefore truncate an over-wide value and reconstruct the wrong proof query. Return a private validated-limit newtype whose methods perform the walk-specific conversions, or make each conversion validate and return Result; callers can still create the validated value at function entry to preserve pre-provider rejection ordering.

Implemented in b6ea184 via the suggested newtype: check_within_server_cap now returns a ServerCappedLimit witness and the walk conversions are its methods, so the check-before-convert ordering is a compile-time property and the release-stripped debug_assert is gone.

Preliminary review — Codex only
The shared wire decoding and extracted builders largely preserve the intended trust boundaries, but two proof-sensitive limit translations still diverge from server behavior: omitted plain-document limits become unbounded, and COUNT range-outer carrier queries use the In-outer limit rules. Two additional suggestions strengthen the aggregate-limit invariant and pin the intentional typed error contract; tests could not be rerun because cargo is unavailable in the environment.

- [BLOCKING] packages/dash-platform-queries/src/documents/aggregate_limit.rs:76-87: Preserve the range-outer carrier limit during COUNT verification
(existing thread: https://github.com/dashpay/platform/pull/4389#discussion_r3801736937)
`carrier_walk_limit` always applies the In-outer carrier semantics, but COUNT uses `RangeAggregateCarrierProof` for two different shapes. `DriveDocumentCountQuery::detect_mode_versioned` also selects this mode for the G8 range-outer shape—`GROUP BY` on one range field with two range clauses on distinct fields. The server detects that shape by counting two range clauses, maps an omitted limit to `Some(MAX_CARRIER_AGGREGATE_OUTER_RANGE_LIMIT)` (currently 10), and rejects explicit limits above 10. The verifier instead passes `None` for an omitted limit and allows explicit values through the shared 100-item cap. Because the limit is part of the proof-sensitive `SizedQuery`, an honest omitted-limit proof is reconstructed differently, while an untrusted full node can produce a proof for a broader query than the server permits. Make COUNT carrier translation shape-aware: preserve `None` only for In-outer carriers, and for range-outer carriers apply the compile-time limit of 10 when omitted and reject explicit values above that limit.

(existing thread: https://github.com/dashpay/platform/pull/4389#discussion_r3801736948)
`check_within_server_cap` returns `()`, while `distinct_walk_limit` and `carrier_walk_limit` independently receive the original `u32` and narrow it with `as u16`. Every current COUNT, SUM, and AVG caller invokes the gate first, so there is no present truncation through those entry points, but that required ordering is represented only by documentation and a release-disabled `debug_assert!`. A future crate-internal caller can skip the gate and silently turn an over-wide request into a different proof query. Return a private validated-limit newtype from the cap check and expose conversions through it, or make each conversion validate and return `Result`, while retaining validation before provider or proof access.

(existing thread: https://github.com/dashpay/platform/pull/4389#discussion_r3801736939)
The `0` sentinel represents an omitted V0 limit or V1 `None`, but this branch constructs a raw `DriveDocumentQuery` with `limit: None`. `DriveDocumentQuery::construct_path_query` forwards that value directly into `SizedQuery`, where it is unbounded. By contrast, `query_documents_typed` maps both omitted forms to `Some(self.config.drive.default_query_limit)` before calling `from_typed_clauses`, so a canonical server proves at most `DEFAULT_QUERY_LIMIT` documents. The verifier therefore reconstructs a broader query than the server executed and can accept an authenticated proof containing every matching document from an untrusted full node. Lower the sentinel to the canonical compile-time default so proof verification uses the same bounded path query as the server.

This PR intentionally changes over-cap lowering from `Error::Config` to `Error::Drive(QuerySyntaxError::InvalidLimit)`, but the regression test checks only the rendered message. Restoring the old error category while preserving the same text would still pass, leaving the documented error-surface contract untested. Match the typed variant and its payload.

Scope cleanup before human review: this PR accreted two things during the automated review rounds that aren't part of its declared decode/builders/verification scope, so they're now their own PRs and this branch was force-pushed without them (range-diff: 6 commits identical, the builders and docs commits shrank, 4 commits moved out).
What remains here is exactly the declared surface: shared wire-request decode + drive-abci dedup, request-bound proof verification for plain document queries, the pure DPNS/DashPay builders, and the rs-sdk delegation. 🤖 Posted autonomously by Claude on behalf of pasta. |

The exact head fixes the in-scope document-limit and typed-error regressions, while the aggregate-verifier work was removed from this PR and explicitly moved to #4432.

Second scope pass, per the refactor-vs-fix separation policy: the remaining behavior changes to pre-existing code — the plain-document limit contract (cap at the server default, InvalidLimit error type, omitted limit lowered to Some(default), and the as-cast truncation) — moved to #4434, which this PR is now stacked on (base retargeted). This PR is a pure refactor plus the new default-off verification/builder surface; its Breaking Changes section now reads none, with the former callouts declared on #4434 where the changes live. Range-diff of the restack: 5 commits identical, 2 trimmed (the DPNS commit lost its interim limit hardening and a now-redundant truncation test; the bind commit lost its limit hunks and was retitled to wire versions only), 1 commit moved to #4434 wholesale. All branches: cargo test -p dash-platform-queries green, full dash-sdk build green. #4433 was rebased onto the new head.

The shared decoders and request-envelope validation appear correct at the exact head, with no blocking trust-boundary defect remaining.

Addressed in f5a1304 with the codec-only feature approach: dash-platform-queries now has a default-on proofs feature carrying drive-proof-verifier and dash-context-provider, and drive-abci's existing default-features = false dependency now resolves to the pure codec — cargo tree -p drive-abci -e normal no longer contains drive-proof-verifier or dash-context-provider.
Two parts of the concern turned out not to materialize, documented in the feature comment:
- dapi-grpc's
clientfeature is transport-free — tonic's channel/TLS stack is behind dapi-grpc's separatetransportfeature (deliberately non-default for wasm), andclientis what exposes the generated message types at all. drive-abci'sserverfeature is already a strict superset ofclient, so no new unification occurs there. - drive's
verifyfeature stays in the base deps so the codec'sdrive::querytypes exist in a standalone build (they're gated onserverORverify); in drive-abci's graph those types come from theserverfeature it already enables, andverifyadds only grovedb's proof-verification code paths, no new external dependencies.
A separate codec crate remains an option if the codec surface grows, but the feature split achieves the decoupling without another workspace member.

Drive-ABCI uses only the request-level protobuf conversion facade, but this unconditional dependency compiles the complete client-oriented `dash-platform-queries` stack into the production server. Its manifest unconditionally enables `drive-proof-verifier`, `dash-context-provider`, DAPI's `client` feature, and Drive's `verify` feature; `drive-proof-verifier` additionally enables the context provider's `mocks` feature and Tenderdash proof crypto. This couples the server's normal dependency graph to client proof verification and unifies Drive's `server` and `verify` feature sets for a small decoder facade. Isolate the neutral conversions in a codec crate or provide a codec-only feature that gates proof-verification modules and dependencies.

The newly public transport-free builders still collapse invalid DPNS labels, missing contract document types, malformed ciphertext lengths, and malformed proof lengths into `InvalidInput(String)`. Direct Rust embedders cannot distinguish these actionable failure classes without parsing unstable display text. Introduce a structured builder-input error with variants and payloads such as the affected field, actual length, and accepted bounds, then wrap it from this crate's `Error`. The SDK conversion can continue mapping the nested error through `to_string()` to preserve its historical `Error::Generic` messages.

The feature split successfully removes the client proof-verification stack from Drive-ABCI's normal dependency graph, and the default-feature query crate tests pass.

- [SUGGESTION] packages/dash-platform-queries/tests/document_limit_lowering.rs:1: Gate the proof-only integration test behind the proofs feature
The new `proofs` feature gates `documents::document_query`, but this integration test imports that module unconditionally. This makes `cargo test -p dash-platform-queries --no-default-features --no-run` fail with an unresolved import, even though `cargo check -p dash-platform-queries --no-default-features` succeeds and this codec-only configuration is now consumed by Drive-ABCI. Gate the integration test behind `proofs` so the supported codec configuration remains testable and compatible with all-target lint commands.

- [SUGGESTION] packages/dash-platform-queries/src/documents/document_query.rs:843-849: Require the response wire version to match the request
(existing thread: https://github.com/dashpay/platform/pull/4389#discussion_r3836721910)
`verify_documents_response` checks whether the request's V0 or V1 arm is served, but delegates the response without confirming that it uses the same arm. The derived `VersionedGrpcResponse` implementation extracts a proof from either response version, while `Platform::query_documents` always returns V0 for a V0 request and V1 for a V1 request. An untrusted transport can therefore pair a request with the opposite response envelope and still reach proof verification. The proof payloads currently have equivalent plain-document semantics, so this is not an immediate authentication bypass, but it violates the API's exact request-binding contract and becomes unsafe if response-version semantics diverge. Reject V0/V1 cross-pairings before delegating to `FromProof`.
- [SUGGESTION] packages/dash-platform-queries/src/documents/document_query.rs:772-775: Require an authenticated data contract for proof verification
(existing thread: https://github.com/dashpay/platform/pull/4389#discussion_r3836721919)
The runtime consistency check establishes only that `contract.id()` matches the request and that the named document type exists. A data contract ID is derived from owner ID and identity nonce rather than the contract contents, while this verifier uses the supplied schema to construct proof paths and decode authenticated document bytes. Consequently, a contract obtained unchecked from the same untrusted transport can retain the expected ID while changing how proof data is interpreted. Document that the explicit contract must be built in, locally trusted, or separately proof-verified, and that the provider-based variant requires its provider to return contracts with equivalent authenticated provenance.
In `packages/dash-platform-queries/src/error.rs`:
- [SUGGESTION] packages/dash-platform-queries/src/error.rs:18-23: Represent builder validation failures with typed variants
(existing thread: https://github.com/dashpay/platform/pull/4389#discussion_r3823526697)
The newly public transport-free builders expose invalid DPNS labels, missing contract document types, malformed ciphertext lengths, and malformed proof lengths through the single `InvalidInput(String)` variant. Direct Rust embedders cannot distinguish these actionable failure classes without parsing unstable display text. Introduce a structured builder-input error with variants and payloads such as the affected field, actual length, and accepted bounds, then wrap it from this crate's top-level `Error`. The SDK conversion can continue mapping the nested error through `to_string()` to preserve its historical `Error::Generic` messages.
Copies the wire-proto -> drive-type decoders for the v1 getDocuments surface from rs-drive-abci's query/document_query/v1/conversions.rs into dash-platform-queries::documents::proto_conversions, verbatim except for a neutral DecodeError replacing the server's QueryError with the exact same message strings. The server is untouched. This is a client-side mirror kept in lockstep by doc contract, the same convention the v0 path uses where CBOR clause decoding mirrors query_documents_v0. Hosting a single shared decode crate that both sides consume is proposed separately; this PR deliberately avoids adding any drive-abci dependency. Upcoming client-side wire decoding (DocumentQuery::try_from_request) consumes these functions; until that commit lands the module carries a temporary allow(dead_code).
…policy is_consensus_valid_label matches exactly the DPNS contract's label schema pattern (consecutive hyphens allowed); is_valid_username is recomposed as that pattern plus the stricter client-side consecutive-hyphen rejection. Its acceptance set is unchanged - the pre-existing test vectors pass as-is - but the consensus check is now available on its own so document builders cannot reject labels the contract accepts.
…rked flows register_dpns_name and create_contact_request were interleaving document assembly (id derivation, salted-domain-hash commitment, property maps, size validation) with fetching, ECDH, and broadcasting. The assembly halves become pure functions - build_dpns_preorder_and_domain_documents and build_contact_request_document - that take caller-supplied entropy/salt/ciphertexts and touch no network or randomness. The networked flows now call them; ids, properties, size-validation bounds, and error messages are unchanged. One addition beyond the extraction: the DPNS builder validates the label against the consensus pattern (is_consensus_valid_label) before assembling. The previous flow did no label validation locally and let the network reject invalid labels; failing locally with a clear message is strictly earlier, and using the consensus pattern (not the stricter client policy) means the builder cannot reject labels the contract accepts.
…-platform-queries File move of the pure builders introduced in the previous commit, unchanged except for the error type: they now return dash_platform_queries::Error::InvalidInput, which dash-sdk maps back to Error::Generic with identical messages, so the SDK surface is byte-for-byte the same. rs-sdk re-exports the builders at their previous paths. This makes the document-assembly half of DPNS registration and DashPay contact requests reachable without the SDK's transport stack; crypto material and randomness stay with the caller.
…d client code DocumentQuery::try_from_request decodes a wire GetDocumentsRequest back into a rich DocumentQuery - the inverse of request encoding. V1 typed clauses go through the same proto_conversions functions the server's v1 handler runs; V0 CBOR where/order_by fields are decoded exactly as the server's query_documents_v0 does. Multi-projection selects and limit Some(0) are rejected, mirroring the server's contracts.
…d embedders verify_documents_response verifies a proved GetDocumentsResponse directly against the wire request that produced it: the wire version (V0/V1 oneof arm) is checked against the platform version's document_query feature bounds (the server's own dispatch gate), prove=false requests are rejected (an honest server answers them unproved), and the request decodes through the shared try_from_request before delegating to FromProof. The query-shape gates (HAVING, GROUP BY, OFFSET, non-documents SELECT - every field the DocumentQuery -> DriveDocumentQuery lowering drops) run inside the shared FromProof<DocumentQuery> impl itself rather than only at the wire entry point. dash-sdk's document fetches verify through that impl, and the SDK talks to the same untrusted evonodes an embedder's transport does, so both paths now reject request shapes no honest server would have proved before any proof machinery runs.

Extracts the document create/replace preparation out of dash-sdk's PutDocument broadcast path into dash-platform-queries: property sanitization for the transition (prepare_document_for_transition) and the entropy/document-id consistency check (ensure_entropy_matches_document_id) that surfaces an id/entropy drift locally instead of after the broadcast has paid a bumped identity-contract nonce. dash-sdk delegates to the shared helpers with unchanged behavior; transport-free embedders (packages/rs-platform-cxx) assemble their own transitions through the same code instead of reimplementing it in C++. Split out of #4389 to keep that PR to its declared decode/builders/verification scope.

Third slice of the
feat/transport-free-embedder-coreseries (#4335; after #4344, #4345, and #4388): gives transport-free embedders the remaining pieces they need to construct and verify Platform interactions without reimplementing SDK logic — the drift-prone code Dash Core's Platform GUI (PastaPastaPasta/dash#67, dashpay/dash#7512) currently hand-builds in C++.Rebuilt (2026-08-22) as six single-purpose commits, each compiling and provable on its own, after review feedback on the previous revision. #4434 (the limit-contract fix this depends on) has merged, so the PR sits directly on
v4.2-dev.Revised (2026-08-23): this PR no longer touches drive-abci at all. The earlier first commit moved the server's v1 proto decoders into this crate and made drive-abci depend on it — that inverted the layering (consensus server depending on an SDK-branded crate, plus client-flavored deps in the server's standalone build graph). The client now carries its own copy of those decoders, mirrored verbatim and kept in lockstep by doc contract — the same convention the v0 CBOR path already uses. Consolidating both sides onto a neutral shared crate is proposed as an independent PR, preferred but not blocking this series.
What was done?
One commit per step, in review order:
feat(sdk): add client-side v1 document-query wire decoders— copies the v1 wire-proto → drive-type decoders from drive-abci'sv1/conversions.rsintodocuments::proto_conversions(crate-private), verbatim except for a neutralDecodeErrorcarrying the exact same message strings. The server is untouched; the module docs pin the lockstep contract with the server file.refactor(sdk): split consensus label validation from client username policy—is_consensus_valid_label(exactly the DPNS contract's label pattern) extracted fromis_valid_username, which is recomposed as consensus-pattern + the stricter consecutive-hyphen policy. Acceptance set unchanged; the pre-existing test vectors pass as-is.refactor(sdk): separate DPNS and DashPay document assembly from networked flows— inside rs-sdk only:build_dpns_preorder_and_domain_documentsandbuild_contact_request_documentbecome pure functions (caller-supplied entropy/salt/ciphertexts; no network, no randomness);register_dpns_name/create_contact_requestcall them. Ids, property maps, validation bounds, and error messages unchanged.refactor(sdk): move pure DPNS and DashPay document builders into dash-platform-queries— file move of those functions, unchanged except the error type (Error::InvalidInput, which dash-sdk maps back toError::Genericwith identical messages). rs-sdk re-exports everything at its previous paths.refactor(sdk): decode document queries from the wire request in shared client code—DocumentQuery::try_from_request, the inverse of request encoding: v1 typed clauses go through the mirrored decoders from commit 1; v0 CBORwhere/order_byare decoded exactly asquery_documents_v0does. ("Shared" here means shared between dash-sdk and embedders — the server is not involved.)feat(sdk): request-bound document proof verification shared by SDK and embedders—verify_documents_responseverifies a proved response against the exact wire request bytes sent. Design change from the previous revision: the request-shape gates (HAVING / GROUP BY / OFFSET / non-documents SELECT — every field theDocumentQuery→DriveDocumentQuerylowering drops) now run inside the sharedFromProof<DocumentQuery>impl itself, not only at the wire entry point. dash-sdk's own document fetches verify through that impl and talk to the same untrusted evonodes an embedder's transport does, so the SDK path gets identical protection — closing the rich-object parity gap the previous revision listed as a follow-up (for plain document fetches). The wire entry point adds the envelope gates on top: wire-version bounds checked againstplatform_version.drive_abci.query.document_query(the server's own dispatch gate) and rejection ofprove: falserequests.How Has This Been Tested?
cargo test -p dash-platform-queries(all green), fulldash-sdkbuild,cargo fmt --check, clippy clean on both changed crates. The pre-existing username test vectors prove commit 2 preserves the acceptance set; commits 1 and 4 are verifiable as pure moves/copies by diffing against the source files.git diff v4.2-dev..HEAD -- packages/rs-drive-abciis empty).Breaking Changes
None: moved items remain importable at their previous
dash_sdkpaths; drive-abci is untouched;is_valid_usernamekeeps its exact acceptance set. One behavior addition:FromProof<DocumentQuery>for plain documents now rejects request shapes no honest server would ever prove (group_by / having / offset / aggregate selects) with a clear error before proof verification — such requests could never verify successfully before; they previously failed later with an opaque proof error.Follow-ups deliberately not in this PR
where/order_bydecode is likewise a byte-for-byte mirror ofquery_documents_v0; the same shared crate is its natural eventual home.
