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.

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.

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.
- [SUGGESTION] packages/dash-platform-queries/src/documents/aggregate_limit.rs:45-87: Encode aggregate-limit validation in the returned type
(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.

- [BLOCKING] packages/dash-platform-queries/src/documents/document_query.rs:1301: Apply the server default when lowering an omitted document limit
(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.

- [SUGGESTION] packages/dash-platform-queries/tests/document_query_wire_roundtrip.rs:340-346: Pin the InvalidLimit error variant in the regression test
(existing thread: https://github.com/dashpay/platform/pull/4389#discussion_r3801736954)
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. |

Final validation — Codex/Sol only (Phase 2 disabled)
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. No in-scope blocking issue, suggestion, or nitpick remains; tests were not rerun because Cargo is unavailable in the verification environment.
Source: reviewer backend model gpt-5.6-sol (general and rust-quality); final verifier backend model gpt-5.6-sol. Orchestration-only: openclaw-agent/cliproxy/gpt-5.6-sol (not reviewer evidence).
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.

…d client code The proto-to-domain decoding for document queries existed only server-side (rs-drive-abci's v1 conversions), so a client verifying a documents proof had to reconstruct the query shape by hand and could silently drift from what the server actually proves. Move the decode logic into dash-platform-queries::documents::proto_conversions with a neutral error type; drive-abci's conversions module becomes a thin mapping onto its QueryError surface with identical error message strings. On top of the shared decoder, DocumentQuery::try_from_request(request, contract) reconstructs the rich query from the wire request (both request versions), and verify_documents_response(...) / verify_documents_response_with_provider_contract(...) give embedders a request-driven verification entry point that delegates to the existing FromProof machinery, resolving the contract explicitly or via ContextProvider::get_data_contract. Round-trip tests cover encode-decode equality for representative queries in both wire versions plus malformed-clause rejection; drive-abci's document_query unit tests pass unchanged (76 cases).
Move the document *content* assembly of rs-sdk's networked DPNS and DashPay flows into transport-free functions in dash-platform-queries, so offline/embedder consumers and rs-sdk share one implementation: - build_dpns_preorder_and_domain_documents assembles the preorder and domain documents exactly as register_dpns_name did: both ids from the same entropy via generate_document_id_v0, saltedDomainHash = sha256d(salt || normalized_label + ".dash"), and the full domain property map (parentDomainName/normalizedParentDomainName, label, normalizedLabel, preorderSalt, records.identity, subdomainRules.allowSubdomains=false). It additionally rejects labels failing is_valid_username up front - previously only enforced by rs-sdk-ffi and platform consensus - so register_dpns_name now fails locally on an invalid label instead of after a network round-trip. - build_contact_request_document assembles the DIP-15 contactRequest id and property map from already-derived crypto material (encrypted xpub/label bytes, key indices, entropy). ECDH, encryption, the 69-byte compact-xpub check, key purpose checks, and recipient fetching stay in rs-sdk; the ciphertext size validations (96-byte xpub, 48-80-byte label, 38-102-byte autoAcceptProof) moved into the builder, with validate_auto_accept_proof also called early in create_contact_request to keep the pre-fetch fail-fast. - ensure_entropy_matches_document_id and prepare_document_for_transition moved from put_document.rs into dash_platform_queries::transition::put_document; rs-sdk re-exports and keeps calling them. Entropy/salt generation and all networking remain in rs-sdk. Builder validation errors surface through the new dash_platform_queries::Error::InvalidInput variant, which rs-sdk maps back to Error::Generic with the exact pre-move messages. New unit tests in dash-platform-queries pin a DPNS known vector (document ids and property maps for fixed label/entropy/salt), mirror the entropy-derives-id relation for contact requests, and cover the negative validation paths.

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.

…er seams Review follow-ups on the transport-free series: - The DPNS document builder validated labels with is_valid_username, whose consecutive-hyphen rejection is stricter than the DPNS contract's schema pattern - consensus accepts names like ab--cd. Split the check: new is_consensus_valid_label matches the contract pattern exactly and gates the builder (so dash-sdk's register_dpns_name no longer refuses consensus-valid labels), while is_valid_username keeps the stricter policy for its existing FFI/wasm gates and now documents the difference. - verify_documents_response now binds the proof to the whole wire request, not just its SELECT projection. GroveDB and Tenderdash proofs authenticate the state and the resolved DriveDocumentQuery, and the DocumentQuery -> DriveDocumentQuery lowering drops group_by, having, offset and prove - so an untrusted transport could otherwise pair a request the real server would have refused (SELECT DOCUMENTS ... GROUP BY age) with a genuine proof for the narrower query it lowers to, and verification would accept it. Every dropped field is now rejected up front, mirroring rs-drive-abci's validate_and_route (non-empty HAVING for a non-aggregate SELECT, GROUP BY under SELECT DOCUMENTS) and reject_offset_off_the_ranked_path (OFFSET off the ranked surface); prove=false is rejected because an honest server answers such a request without a proof at all. The pre-existing aggregate- projection rejection (COUNT/SUM/AVG, which use a different proof shape) moves into the same gate. Five tests cover the rejections with a ContextProvider that panics if reached, pinning that they fire before any proof machinery runs. - TryFrom<&DocumentQuery> for DriveDocumentQuery converts the limit with a checked u16::try_from instead of an `as` cast. Drive's limit is a u16 and the server refuses anything larger with InvalidLimit, so the cast turned a request for 65537 documents into a 1-document query - and a proof for that query then verified. This matches the offset conversion right below it, which already refused rather than truncated. - try_from_request documents that it mirrors the server's wire-shape decode, not validate_and_route business rules, and points at the entry point that closes the gap. - The CI transport-leak guard also asserts wasm-sdk's wasm32 tree stays free of the native transport stack. - The proof-vector corpus gains a README with an explicit coverage matrix: the four documents-family cases pin query shape and clean decode failure but stop before the BLS check (placeholder payloads in the fixture state); identity, contested, and quorum-sig families run the full pipeline. This corrects the corpus commit's broader claim.

…ions The verifier dispatched 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 before decoding or executing the request, so an untrusted transport could attach a valid proof to a request an honest server at the supplied PlatformVersion could not have answered (PlatformVersions 1-11 have bounds 0..=0 and reject every V1 request with UnsupportedQueryVersion). Derive the request feature version from the oneof arm and reject it against the supplied bounds before anything is decoded, in both verify_documents_response entry points — the same check_version gate the server's query_documents dispatch runs.
The transport-free preorder/domain builder takes the salt as an argument, so the front-running protection the preorder commitment provides now rests on the embedder: a fresh CSPRNG 32-byte salt per registration attempt, and salt/label/domain-document secrecy until the preorder create transition is confirmed. Spell out both obligations - and that the networked SDK's register_dpns_name (StdRng::from_entropy, submit-and-wait before broadcasting the domain document) is the reference behavior - on the builder's docs.
The extraction from drive-abci widened where_operator_from_proto, value_from_proto, where_clause_from_proto, order_clause_from_proto and having_clause_from_proto to pub, but the cross-crate consumers (drive-abci's v1 conversions, the SDK decode path) only use DecodeError, the plural request-level decoders and select_from_proto. Narrow the singular helpers to pub(crate) so the shared decode surface stays as small as its actual contract.

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

- [SUGGESTION] packages/dash-platform-queries/src/documents/document_query.rs:829-835: Exercise a successful request-driven proof verification
No repository test successfully reaches this new delegation. The direct tests mutate requests into rejected shapes, use `GetDocumentsResponse::default()`, and install `NeverCalledProvider`, while the round-trip tests stop after request decoding. The existing document vectors in `drive-proof-verifier` also contain placeholder payloads and intentionally end in a document-decoding error, so they do not cover this composition. Add deterministic server-generated or fixture-backed proofs that pass through `verify_documents_response` for both V0 and V1 request envelopes, including an omitted limit and a nontrivial clause or cursor. Route at least one successful case through `verify_documents_response_with_provider_contract` to cover provider resolution before delegation.

That crate unconditionally depends on `drive-proof-verifier`, `dash-context-provider`, DAPI's client feature, and Drive's `verify` feature; Cargo therefore unifies Drive's `server` and `verify` feature graphs in the Drive-ABCI build and also pulls in proof-verification dependencies such as Tenderdash crypto and the context provider's mock feature. Move the neutral protobuf conversions into a small shared codec crate, or add a codec-only feature that gates proof-verification modules and dependencies, so decoder deduplication does not couple the production server to the client proof stack.

- [SUGGESTION] packages/dash-platform-queries/src/error.rs:18-23: Represent builder validation failures with typed variants
The newly public transport-free builders collapse distinct actionable failures into `InvalidInput(String)`: invalid DPNS labels, missing contract document types, and each ciphertext or proof length violation can only be distinguished by parsing display text. Direct Rust embedders therefore lack a stable way to decide whether to correct a label, regenerate cryptographic material, or replace the supplied contract. Introduce a typed builder-input error with variants and structured payloads such as the field, actual length, and accepted bounds, then wrap it from this crate error. The SDK conversion can continue mapping that nested error to `Error::Generic(error.to_string())` to preserve its historical messages.

🟡 Suggestion: Exercise a successful request-driven proof verification
No repository test successfully reaches this new delegation. The direct tests mutate requests into rejected shapes, use GetDocumentsResponse::default(), and install NeverCalledProvider, while the round-trip tests stop after request decoding. The existing document vectors in drive-proof-verifier also contain placeholder payloads and intentionally end in a document-decoding error, so they do not cover this composition. Add deterministic server-generated or fixture-backed proofs that pass through verify_documents_response for both V0 and V1 request envelopes, including an omitted limit and a nontrivial clause or cursor. Route at least one successful case through verify_documents_response_with_provider_contract to cover provider resolution before delegation.

Issue being fixed or feature implemented
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++.Stacked on #4434 (the plain-document limit-contract fix, which the verification surface here depends on); will be retargeted to
v4.2-devwhen it merges. Seven commits, all within the declared scope below — this PR moves and deduplicates code and adds the new default-off surface; every behavior change to pre-existing code was split out (see the scope note).What was done?
DocumentQuery::try_from_requestdecodes a wire-formatGetDocumentsRequestback into a richDocumentQuery— the inverse of request encoding — by liftingdrive-abci's server-side proto conversions into shared client code, so the bytes the server decodes and the client verifies go through the same code.drive-abcinow consumes the shared conversions (deduplicated, −382 lines in itsconversions.rs). Round-trip coverage intests/document_query_wire_roundtrip.rs.documents::verify_documents_responsedelegating todrive-proof-verifier'sFromProof, keyed on the exact request bytes sent. It binds the proof to the whole request, not just the part that survives lowering: GroveDB/Tenderdash proofs authenticate the state and the resolvedDriveDocumentQuery, and theDocumentQuery→DriveDocumentQuerylowering dropsgroup_by,having,offsetandprove— so each of those is rejected up front, mirroringrs-drive-abci'svalidate_and_routeandreject_offset_off_the_ranked_path. Without that, an untrusted transport could pair a request the real server would have refused (SELECT DOCUMENTS … GROUP BY age) with a genuine proof for the narrower query it lowers to. The request envelope is bound the same way: the wire version (V0/V1oneof arm) is checked againstplatform_version.drive_abci.query.document_query's feature-version bounds before anything is decoded — the samecheck_versiongate the server'squery_documentsdispatch runs — and the limit contract it relies on (cap at the server's compile-time default, omitted limit lowered to the concrete default) comes from fix(sdk): enforce the server's limit contract when lowering document queries #4434, which this PR is stacked on.build_dpns_preorder_and_domain_documents(salted-domain-hash preorder/domain pair) anddashpay::build_contact_request_document, extracted from rs-sdk's networked flows. Crypto material is supplied by the caller — ECDH/key custody stays out of this crate.is_consensus_valid_label(matches the DPNS contract regex; gates the builders) fromis_valid_username(stricter client-side policy, e.g. consecutive-hyphen rejection) so builders cannot reject labels the contract accepts.rs-sdkre-exports everything at its old paths; no consumer changes imports.Scope note (2026-08-20): three pieces were split out to keep this PR a pure refactor + new default-off surface:
verify_documents_responsenever routes aggregate selects);put_documenttransition-preparation helpers → refactor(sdk): share document transition preparation with embedders #4433 (stacked on this PR; needed by feat(sdk): add transport-free CXX bindings #4416, not by this PR's surface);TryFrombehavior changes that the new verification surface depends on but that stand alone as fixes to the existingFromProofpath).How Has This Been Tested?
cargo test -p dash-platform-queries(38 unit + 18 integration tests, including wire round-trip, request-binding rejections — wire-version bounds,group_by/having/offset/prove— each pinned to fire before proof machinery via a panickingContextProvider, and builder/validation coverage); fulldash-sdkbuild;cargo fmt --check; clippy clean. The limit-contract coverage lives in fix(sdk): enforce the server's limit contract when lowering document queries #4434 and the aggregate verifiers' in fix(sdk): enforce server limit parity in the aggregate proof verifiers #4432, each with the code it tests.Breaking Changes
None: this PR moves code and adds a new default-off surface. Moved items remain importable at their previous
dash_sdkpaths;drive-abci's request decoding behavior is unchanged (same conversions, now shared);is_valid_usernamekeeps its exact acceptance set (recomposed as consensus-regex + the stricter client-side hyphen rule, same test vectors). The behavior changes formerly listed here — the limit cap, theInvalidLimiterror type, and the omitted-limit default — are #4434's, where they are declared.Follow-ups deliberately not in this PR
The rich-object path (
FromProofwith a caller-constructedDocumentQuery) still routes through the same conversion that silently dropsgroup_by/havingfor plain document fetches. The new pre-proof rejections cover only the wire-request entry points; a caller who hand-builds a server-invalid rich object and verifies against a malicious node's proof retains the (pre-existing, misuse-conditional) parity gap. The limit cap, by contrast, was fixed in the shared conversion and covers both paths.The aggregate verify paths' remaining gaps (wire-version gating for their entry points; mode-aware limit-absence enforcement beyond the COUNT carrier shapes) now track under fix(sdk): enforce server limit parity in the aggregate proof verifiers #4432, which owns that surface.
