Issue being fixed or feature implemented

Platform pinned GroveDB at 6fc7e1e8 together with the QuantumExplorer rust-rocksdb fork, and rust-dashcore at a revision from before GroveDB's bincode moved to the published grovedb-bincode crate. This PR advances those dependencies and adapts Drive, the FFI and the wasm SDK to the GroveDB API changes, without changing how Platform decodes anything. The untrusted-decoding adoption in #4625 builds on top of it.

Companion changes are merged: GroveDB #948, GroveDB #949, GroveDB #951 (develop f75fa36230902b983d231572b6aa2c17eb72cf7d) and rust-dashcore #1005 (dev e4208c90786a6854bd498315bcb571ef24182c15).

What was done?

  • Advance GroveDB to develop f75fa362 (6.0.0 plus fix(dashmate): wrong envoy config path on windows #949 and feat(dashmate): verbose connect ENOENT /var/run/docker.sock error #951, about fifty commits since 6fc7e1e8, including the V1 proof hardening series) and rust-dashcore to dev e4208c90. Use rocksdb 0.25.0 from crates.io instead of the rust-rocksdb fork. Make the workspace bincode dependency an alias for the published grovedb-bincode 2.1.0 so GroveDB, rust-dashcore and Platform share one set of bincode traits; no Cargo patch is needed.
  • Build RocksDB 11.8.1 for the prebuilt static library in the Docker image and in the librocksdb GitHub action, matching librocksdb-sys 0.19.0+11.8.1. RocksDB 11's C API dropped the in_range slice-transform callback, so bindgen against the 10.x headers no longer compiles the rocksdb crate.
  • Adapt to GroveDB feat(dashmate): verbose connect ENOENT /var/run/docker.sock error #951, which replaced the per-call propagate_backward_references flag with a backward_references_policy on insert, delete, clear and batch options (default Maintain on GroveDB V4, Platform's PV14; PV13 stays on V3) and added may_contain_backward_references to EstimatedLayerInformation. Drive stores no backward-reference participants, so its ten option sites select Skip, which routes every write through the released V4 executor paths and keeps PV14 fees exactly where they were; under Maintain the participant scans of removed index subtrees raised document delete, transfer and purchase processing fees by 5 to 23 percent. Every estimation layer Drive builds declares may_contain_backward_references: false, so estimates are unchanged too. When Drive starts storing participants, the policy flips to Maintain under a new protocol version. GroveDB fix(dashmate): wrong envoy config path on windows #949 changes only V4 recursive subtree discovery over non-Merk descendants and needs no Drive change.
  • Adapt to the other GroveDB API changes: element verification aligned with the prover's right-to-left traversal (GroveDB now checks it strictly), and the new backward-reference element variants rendered by the FFI and wasm SDK path-element queries.
  • Verify a paged document query's cursor document in the page's walk direction. The prover merges the one-key cursor lookup into the page proof in the page's orderBy direction, and GroveDB fix(scripts): update configure_test_network for hpmn #863 now rejects a layer proof read in the other op family, which failed every proved descending page with a cursor. When a $id-ordered page merges its cursor lookup onto the primary-key layer itself (also for history-keeping types, whose cursor sits one level below), the prover now keeps the requested direction and reserves the extra limit slot only when the page's items do not already cover the cursor, since GroveDB 6 also rejects a layer returning more rows than the verifier's limit; round-trip tests page by $id in both directions with inclusive and exclusive cursors. The drive-abci contestant-votes test helper now verifies with the requested order and cursor, as the SDK's proof verifier does, and the proved test pages with cursors and limits in both directions.

How Has This Been Tested?

Local macOS: cargo fmt --all --check; cargo clippy --workspace --all-targets --all-features --locked -- --no-deps -D warnings; cargo nextest run -p drive --all-features (3,755 passed); cargo nextest run -p drive-abci --all-features (3,113 run). Under Maintain twelve PV14 fee baselines in drive-abci moved; with Skip selected they pass at their existing values, PV13 and PV11 siblings included. The earlier round on GroveDB 985ece65 also ran the CI nextest package set (14,855 passed) and built the Docker deps-rocksdb stage with RocksDB 11.8.1. No device or browser execution and no live network upgrade were exercised.

Breaking Changes

Rust consumers that serialize Platform or Core types must use the published grovedb-bincode 2.1.0 crate, since bincode trait identities now come from it. Existing bincode encodings and the C ABI are unchanged. Fees are unchanged at every protocol version.

…de 2.1.0

Advance GroveDB to develop 985ece65 (6.0.0) and rust-dashcore to dev
057e79cd, use rocksdb 0.25.0 from crates.io instead of the rust-rocksdb
fork, and make the workspace bincode dependency an alias for the published
grovedb-bincode 2.1.0 so GroveDB, rust-dashcore and Platform share one
set of bincode traits without a Cargo patch.

Adapt to the GroveDB API changes: batch options in Drive's grove
operations, element verification aligned with the prover's right-to-left
traversal, which GroveDB now checks strictly, and the new backward
reference element variants rendered by the FFI and wasm SDK path element
queries.

BREAKING CHANGE: Rust consumers serializing Platform or Core types must
use the published grovedb-bincode 2.1.0 crate; bincode trait identities
now come from it. Wire encodings and the C ABI are unchanged.

librocksdb-sys 0.19.0+11.8.1 (pulled in by rocksdb 0.25) targets the
RocksDB 11 C API, which dropped the deprecated in_range callback from
rocksdb_slicetransform_create. The Docker image and the librocksdb
GitHub action still built RocksDB 10.4.2 and 9.9.3, so bindgen produced
the six-argument signature and the rocksdb crate failed to compile
against it. Build 11.8.1 in both places to match the vendored version.

GroveDB now refuses a V1 layer proof that is read in the other op family
(grovedb #863): a layer proof is emitted entirely in the family of the
direction its query walks. When a document query carries a startAt or
startAfter cursor, the prover merges the one-key cursor lookup into the
page proof, and since grovedb's merge needs every input to walk the same
way, the cursor layer is emitted in the page's orderBy direction. The
verifier rebuilt that lookup as a fresh ascending single-key query, so
every proved descending page with a cursor failed with InvalidProof.

Read the cursor layer in the page's direction when it is verified as a
subset of the page proof. The direction comes from the same query
builder the prover uses and never depends on the cursor document; a
single key decodes identically either way.

…der and cursor

The proved contestant-votes helper verified every proof with a fixed
ascending, unlimited query regardless of the request it had just sent.
GroveDB now refuses a layer proof read in the other op family, so the
descending request failed with InvalidProof. Mirror the request's order,
count and cursor into the verifier query, as the SDK's proof verifier
does.

📝 Walkthrough

Walkthrough

The changes update workspace and RocksDB dependencies, correct cursor pagination and proof-direction handling, configure backward-reference policies and estimation metadata, and add rendering support for new GroveDB element variants.

Changes

Platform alignment and query behavior

Layer / File(s) Summary
Workspace and build dependency updates
.github/actions/librocksdb/action.yaml, Dockerfile, Cargo.toml, packages/*/Cargo.toml
Workspace crates now use grovedb-bincode 2.1.0 and updated DashCore and GroveDB revisions. RocksDB now uses version 11.8.1 and crates.io 0.25.0.
Cursor pagination and proof direction
packages/rs-drive/src/query/mod.rs, packages/rs-drive/src/verify/..., packages/rs-drive/tests/query_tests*.rs
Merged cursor queries account for cursor coverage and preserve query direction. Proof tests cover inclusive and exclusive cursors in both directions.
Proved vote pagination
packages/rs-drive-abci/src/execution/.../masternode_vote/mod.rs
Proved vote queries now use the request limit, cursor, and ordering. Tests cover paged ascending and descending results.
Backward-reference operation and estimation settings
packages/rs-drive/src/util/grove_operations/*/v0/mod.rs, packages/rs-drive/src/drive/**
Grove operations use BackwardReferencesPolicy::Skip. Estimated layers explicitly mark backward references as absent.
Backward-reference element rendering
packages/rs-sdk-ffi/src/system/queries/path_elements.rs, packages/wasm-sdk/src/queries/system.rs
FFI and WASM rendering now supports bidirectional and backward-reference variants, including payloads, sums, targets, and type names. Tests cover the new variants.

Final validation — Phase 2 only (queue backlog)

Both supplied findings are confirmed against the exact head. The GroveDB upgrade exposes a direction mismatch that prevents verification of descending primary-key pages with a cursor, and the updated contestant-vote proof helper has no calls exercising its newly forwarded cursor or limit. Verification was source-based; reviewer-reported test results were not independently rerun.

- [BLOCKING] packages/rs-drive/src/verify/document/verify_start_at_document_in_proof/v0/mod.rs:59-63: Align primary-key cursor verification with the merged proof direction
  For a non-history document query ordered by `$id desc` with a cursor, the cursor lookup and main query address the same primary-key tree. Their merged query therefore operates directly on that tree, but `construct_path_query_operations` unconditionally sets `merged.query.query.left_to_right = true` at `query/mod.rs:2061`. These new lines instead select descending verification. The newly pinned GroveDB explicitly rejects upright proof operations in a right-to-left V1 walk, so this valid page cannot be verified. The ascending-root override is justified for separate cursor and index branches, but not when both queries land on the same primary-key path. Preserve the requested document-layer direction in the prover for this case and add ascending/descending primary-key cursor round-trip tests. Reverting only the cursor verifier to ascending is insufficient: `verify_proof_keep_serialized_v0` subsequently verifies the main subset in the requested descending direction.

In `packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/masternode_vote/mod.rs`:
- [SUGGESTION] packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/masternode_vote/mod.rs:3079-3081: Exercise the forwarded cursor and limit in a proved vote request
  All four calls to `get_proved_contestant_votes` in `test_proved_contestant_votes_query_request` pass `None` for both the count and cursor. Consequently, the new cursor conversion never executes, and reverting the verifier's `limit` and `start_at` fields to their previous hardcoded `None` values would leave this test passing. The neighboring non-proved pagination test does not exercise proof verification. Add proved requests with a nonempty cursor and a limit smaller than the available results, covering inclusive/exclusive cursors in ascending and descending order, and compare the returned identifiers with the corresponding slices of the full voter sequence.

…ges onto its own layer

A startAt/startAfter page proof merges the one-key cursor lookup with the
page query. For an index-ordered page the two live under different
subtrees, so the merge synthesizes a root above both and that root is
walked ascending so the cursor branch spends its reserved limit + 1 slot
first; the verifier never sees that root. A $id-ordered page addresses
the primary-key tree directly (a history-keeping type's cursor sits one
level below it), so the merge point is the page query's own root layer.
Flipping that layer ascending contradicts the descending direction the
verifier reads it in, and the reserved slot makes an inclusive page
return limit + 1 rows matching the page query. GroveDB 6 rejects both:
"inverted op in a left-to-right walk" and "Proof returns more data than
limit".

When the merge lands on the page query's own layer, keep the requested
direction, and reserve the extra slot only when the page's items do not
already cover the cursor key. Round-trip tests page the family contract
by $id in both directions with inclusive and exclusive cursors, for
plain and history-keeping document types, verifying every page's proof.

The proved contestant-votes test only requested whole result sets, so the
helper's forwarding of the request's count and cursor into the verifier
query was never exercised. Add paged proved requests over the 50-voter
contender: a limit smaller than the result set with inclusive and
exclusive cursors in both directions, plus a short final page, each
compared with the matching slice of the full ascending voter sequence.

Final validation — Phase 2 only (queue backlog)

Both prior findings are fixed at head 7b596ff, and no in-scope findings remain. Independent locked, offline, all-features validation passed all 57 Drive query tests, all 4 history-query tests, and the proved contestant-vote pagination test; the full-range diff check also passed. Full-workspace, browser, device, and live-network validation were not repeated.

…sum-tree tripwire

grovedb invalidates its restore session on a failed chunk, so the target asks Tenderdash to restart the snapshot instead of refetching one chunk. The sum-tree probe is removed; the full two-instance round trip stays ignored until the grovedb pin carries dashpay/grovedb#840, which arrives with the GroveDB 6.0.0 bump in dashpay#4635.

The pin cannot move to dev head yet: dashpay/rust-dashcore#1005 (GroveDB
bincode) needs #4635 first. Until then the pin points at
dashpay/rust-dashcore@697bfb72, which is the current pin 93260bf plus the
cherry-picked #989 fix (dash-spv collects the scripts derived by every
application of a block). Verified end to end on the support wallet: a
from-seed rebuild ends with 0 phantom coins.

Keep the workspace bincode alias for grovedb-bincode 2.1.0. v4.2-dev
moved rust-dashcore to 697bfb72, the pre-squash head of rust-dashcore
#989 (dash-spv derived-script fix), which predates the grovedb-bincode
switch from #1005; pin rust-dashcore dev at e4208c90 instead, the squash
merge of #989, which carries both, plus the two key-wallet fixes merged
in between (#1001, #1004).

Use the same direction as prove_elements_v0

prove_elements_v0 builds grovedb::Query::default(), while verify_elements_v0 rebuilds the query with Query::new_with_direction(false). The reachable callers provide only path and keys; they do not provide another direction. Since grovedb::Query defaults to left-to-right traversal, GroveDb::verify_query_raw can reject these proofs because the operation families differ. Use Query::default() or Query::new_with_direction(true) in the verifier.

…ntrusted-bincode

Brings v4.2-dev (through e096d1e) and #4635's rust-dashcore dev pin.
The wallet storage blob codec keeps both sides: the base's sealed
PersistableBlob registration gates encode, and the same macro now also
admits a type to the untrusted decode path, so BlobDecode stays the
opt-in for decoding while impl_blob_decode! covers the legacy v8 address
pool rows a migration still reads. Nested identity-key and asset-lock
proof bytes decode through the untrusted decoder under the row budget.
The wallet FFI keeps both new test modules and the untrusted decode of
the host-supplied asset lock proof.

On the CodeRabbit note about verify_elements_v0 (lines 40-42): no change needed, the directions already match. grovedb_query::Query is #[derive(Default)], so Query::default() in prove_elements_v0 carries left_to_right: false (a bool default); it is Query::new() that sets true. verify_elements_v0 therefore rebuilds the query with Query::new_with_direction(false) on purpose, and should_prove_and_verify_elements in that module proves and then verifies a live element under GroveDB 6's strict op-family check, passing in the Rust CI job on this head. Switching the verifier to Query::default() would be equivalent; switching it to new_with_direction(true) would break it.

Final validation — Phase 2 only (queue backlog)

The final head addresses both previously verified findings. Primary-key cursor proof verification now preserves the requested traversal direction, and the proved contestant-vote test now exercises forwarded limits and inclusive/exclusive cursors in both ascending and descending orders; no additional in-scope issues were identified.

Advance the GroveDB pin from 985ece65 to develop f75fa362 (GroveDB #949,
#951 and #952). GroveDB #951 replaces the per-call
propagate_backward_references flag with a backward_references_policy on
insert, delete, clear and batch options, defaulting to Maintain on GroveDB
V4 (Platform PV14; PV13 stays on V3). Drive selects Maintain explicitly so
ordinary writes keep backward-reference participants consistent without
each caller predicting them, and every EstimatedLayerInformation declares
may_contain_backward_references: false because Drive stores no
participants, which keeps estimates byte-identical to the previous
flag-less behaviour. GroveDB #949 only changes V4 recursive discovery over
non-Merk descendants and needs no Drive change.

Re-pin twelve PV14 processing-fee baselines in drive-abci: transitions
that remove emptied index subtrees (document delete, transfer and
purchase, group-action confirm) now pay for GroveDB's participant scan of
those subtrees, while batch preparation through retained Merk nodes bills
slightly fewer reads on DPNS create and document replace. PV13 fees are
unchanged.

Drive stores no backward-reference participants, so GroveDB's default
Maintain policy had nothing to keep consistent, while its participant
scans of removed index subtrees raised PV14 processing fees on document

Drive write through the released V4 executor paths, which returns the
twelve drive-abci PV14 fee baselines to their existing values. Flip to
Maintain under a new protocol version once Drive stores participants.
