Issue being fixed or feature implemented

Compound ranked indexes (#4393) require every leading property pinned with ==, so "rank classes for these three identities" takes three requests. The IN rejection message called this "a future capability" — this PR builds it, per the design sketch's walk-and-merge approach (per-branch proofs + deterministic client-side merge; no new grovedb primitives).

What was done?

  • Grammar (prefix_pins_from_where_clauses, shared by both surfaces): at most one IN across the leading prefix properties, 2..=10 distinct elements (MAX_PREFIX_IN_BRANCHES, a hard rejection like the limit ceiling), null legal (addresses the absent-value / empty-segment prefix), single-element IN normalized to ==. OFFSET is rejected together with IN — rank-skip is attested per-secondary and has no meaning across a branch union.
  • Resolution: encode_prefix_branches produces one encoded segment list per branch in canonical order (ascending encoded bytes, independent of the caller's element order; duplicates post-encoding rejected). Query structs carry prefix_branches; single-branch requests are byte-identical to before.
  • Execution: each branch walks its own axis secondary with the full limit; pages merge by (aggregate in walk direction, encoded prefix ascending, group key in walk direction). Merged entries carry in_key (the branch's encoded segment) since one group key can appear under two prefixes.
  • Proofs: the proved response is a versioned container of per-branch grovedb indexed-axis proofs. The verifier re-derives the branch set from its own resolution, verifies each branch against its own path, requires one root hash across branches, and re-merges — the merge needs no proof because the merged page is a deterministic function of independently proved branch pages (per-branch completeness composes; the lemma is documented in branches.rs).
  • Wire: RankedEntry gains optional in_key (additive; all clients regenerated). No request-side changes — WhereClause.IN was already wire-stable.
  • Tests: merge order incl. a cross-prefix aggregate tie and a mixed null+value IN; the container tamper matrix (reordered / dropped / duplicated / re-versioned / padded branch proofs all fail); degenerate single-element IN == == byte-for-byte; grammar rejections (cap, empty list, second IN, scalar operand, duplicate encodings); abci wire e2e with in_key mapping both prove states.

How Has This Been Tested?

cargo test -p drive --features server,verify (3392 passed), -p drive-abci document-query v1 module (68), -p dpp (3907), -p drive-proof-verifier (267), -p dash-sdk (208); clippy --tests clean across all touched crates.

Breaking Changes

None. PV14 is unreleased; the accepted grammar widens within the current generation, previously-rejected requests only. Single-prefix requests, responses, and proofs are byte-identical to before.

📝 Walkthrough

Walkthrough

Ranked and HAVING queries now support bounded multi-value IN prefix branching. Branches are merged deterministically, tagged with in_key, and verified through branched proof flows. Protobuf clients, mocks, documentation, fixtures, and tests were updated.

Changes

Ranked-index IN branching

Layer / File(s)Summary
Query contracts and branch resolution
book/src/drive/document-ranked-trees.md, packages/dapi-grpc/protos/platform/v0/platform.proto, packages/rs-drive/src/query/drive_document_ranked_query/*, packages/rs-drive/src/query/drive_document_having_query/*, packages/dapi-grpc/clients/platform/v0/objective-c/Platform.pbobjc.h
Query modes use PrefixPin and prefix_branches. One bounded branching IN is accepted. Null values use empty path segments. Invalid shapes and incompatible OFFSET usage are rejected.
Branch execution and deterministic merging
packages/rs-drive/src/query/drive_document_ranked_query/branches.rs, packages/rs-drive/src/query/drive_document_ranked_query/execute_top_k.rs, packages/rs-drive/src/query/drive_document_having_query/execute_range.rs
Each encoded branch is queried independently. Results are validated and merged by aggregate, branch key, and group key. Branched proof envelopes are generated from committed state.
Multi-branch proof verification
packages/rs-drive/src/verify/document_ranked/verify_ranked_top_k_proof/v0/mod.rs, packages/rs-drive/src/verify/document_having/verify_having_range_proof/v0/mod.rs, packages/rs-drive-proof-verifier/src/proof/*
Verifiers validate branch paths, branch sets, empty branches, limits, and shared root hashes before merging verified entries.
Wire propagation and integration coverage
packages/dapi-grpc/clients/*, packages/rs-drive-abci/src/query/document_query/v1/dispatch/mod.rs, packages/rs-sdk/src/mock/requests.rs, packages/rs-drive*/**/tests.rs, packages/rs-*/Cargo.toml
RankedEntry.in_key is serialized and exposed across generated clients, dispatch, SDK mocks, and integration tests. Tests cover ordering, absent branches, proofs, transactions, validation errors, and dependency updates.

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

Merge Risk:🟡 Moderate · up to ca50c

The new multi-branch IN query behavior still has unresolved validation and bounds-safety issues: malformed inputs may produce invalid query branches, and an invalid branch index may panic instead of failing safely; OFFSET 0 behavior also differs from the stated contract. These can cause query failures or runtime instability, so the PR is not merge-ready until the issues are fixed or explicitly accepted.

Converting to draft: the multi-branch proof will become a single grovedb envelope (shared ancestor layers + one multi-key proof at the branching level + per-branch secondary proofs) instead of the length-prefixed container of per-branch proofs — the container framing inside grovedb_proof was compensating for a missing grovedb primitive, and the primitive is buildable without storage changes. grovedb-side work first; this PR will then swap the container for the one-proof call.

Update the rejection text: pins are no longer equality-only.

no_covering_index_message now receives PrefixPin, which can carry several values. The message still states "every leading property pinned by an equality where clause" and "with equality pins on [...]". A user who sent IN and hit the no-covering-index path reads advice that contradicts the accepted grammar.

Use neutral wording, for example "pinned by an equality or INwhere clause" and "with pins on [...]".

Update the stale doc comment on the renamed test.

The OFFSET × IN exclusion is enforced only in mode detection. Both the multi-branch prover and the multi-branch verifier hard-code skipped: 0, yet both still pass self.offset into the per-branch GroveDB call. A query that carries offset > 0 with several branches therefore produces a page that matches no rank window, and the proof still verifies because both sides make the same wrong assumption.

  • packages/rs-drive/src/query/drive_document_ranked_query/execute_top_k.rs#L54-L83: return a CorruptedDriveState error when self.offset != 0 before running the per-branch walks.
  • packages/rs-drive/src/verify/document_ranked/verify_ranked_top_k_proof/v0/mod.rs#L98-L104: apply the same rejection before decoding the branch container, so the verifier does not accept a page whose rank base it cannot attest.

303-316: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Consider encoding the non-empty invariants in the types.

prefix_branches documents "Always at least one branch" and PrefixPin::values documents "never empty". Both are public fields with no enforcement. indexed_property_name_tree_path indexes prefix_branches[branch] directly, so an empty vector panics. The resolver and the grammar keep both invariants today, but a hand-built query (as several tests do) can break them.

A small constructor or a NonEmpty-style wrapper would make the invariant checked rather than documented. This is optional; the reachable paths are covered.

Add the two truncation cases to the container tamper matrix.

The matrix covers reorder, drop, duplicate, unknown version, and trailing bytes. decode_branch_proofs also rejects "truncated branch count", "truncated proof length", and "truncated proof body". Those three arms have no coverage. A one-byte container and a container whose last declared length exceeds the remaining bytes would pin them cheaply.

These are pure byte-level cases, so a small unit test next to decode_branch_proofs would be an alternative to extending this test.

Validate aggregate-axis homogeneity before sorting.

When mixed variants reach merge_branch_pages, returning Ordering::Equal makes the comparator non-transitive. For example, Count(1), Sum(5), and Count(2) can form a comparison cycle through the key tie-breakers. sort_by may panic instead of returning the stored CorruptedDriveState error. Validate all RankedEntryValue::axis() values before sort_by, then use an infallible comparator.

Return an error instead of indexing prefix_branches directly.

indexed_property_name_tree_path is public and indexes self.prefix_branches[branch]. An out-of-range branch panics. All current callers derive branch from 0..self.prefix_branches.len() or from decode_branch_proofs, which validates the count, so this is not reachable today. The method already returns Result, so a bounds check costs one line and removes the panic path from the public surface.

Update the stale part of the prefix_pins doc comment.

The retained text describes (property, value) tuples and "equality where pins". The field now holds PrefixPin values with a values: Vec<Value> list, and one pin can carry an IN element list. Align the first sentences with the new type so the docs do not contradict the added IN note.

Preliminary review — Codex only

The branch encoding, deterministic merge, and verifier reconstruction are consistent when every requested prefix subtree exists. A valid multi-value IN request still fails in full if any selected prefix has no documents, so the advertised union behavior is incomplete across both proved and unproved execution; several smaller public-API and documentation issues also remain.

- [BLOCKING] packages/rs-drive/src/query/drive_document_ranked_query/execute_top_k.rs:59-70: An unmatched IN element aborts the entire branch union
Each `IN` branch is executed independently and then collected with `collect::<Result<...>>()`, so the first selected prefix whose terminal tree has never been created aborts the whole request. The existing `unknown_prefix_value_errors_rather_than_fabricating_an_empty_page` test confirms that a never-written prefix produces an error; consequently `prefix IN [existing, absent]` loses the existing branch's valid results instead of treating the absent branch as empty. `execute_range_no_proof` and both proof-generation loops have the same behavior. The proved path requires more than swallowing `PathNotFound`: the proof must authenticate absence at the shared branching layer while still proving existing branch pages, so proved and unproved execution remain equivalent.

- [SUGGESTION] packages/rs-drive/src/query/drive_document_ranked_query/index_picker.rs:241-320: Reject malformed prefix-pin shapes before building branches
`encode_prefix_branches` is public, but it relies on shape constraints enforced only by mode detection. An empty `PrefixPin::values` collapses the product to zero branches, after which callers select branch zero and panic; multiple multi-valued pins create a Cartesian product that exceeds the one-dimensional `in_key` contract and bypasses the grammar's branch ceiling. Validate these two invariants at this shared encoder boundary so malformed safe-Rust inputs return a query error rather than producing an unusable branch set.

- [SUGGESTION] packages/rs-drive/src/query/drive_document_ranked_query/path.rs:87-113: Bounds-check the public branch path lookup
The rustdoc still links to the removed `Self::equality_prefix_values` field, and `indexed_property_name_tree_path` directly indexes `self.prefix_branches[branch]`. Current resolver-driven callers supply valid indices, but this is a public method on a publicly constructible query and already returns `Result`; an out-of-range branch should therefore return an error instead of unwinding. Update the link to `Self::prefix_branches` and retrieve the branch with `get(branch)` before calling the shared path builder.

The outside-diff finding (stale "equality where clause" wording in no_covering_index_message) is also fixed in 7cea92f: the index-shape text now reads "pinned by an equality or INwhere clause" and the pin list drops the "equality" qualifier.

Also in that commit: the proof shape moved from the length-prefixed container to one grovedb branched envelope (dashpay/grovedb#793) — shared ancestor layers once, one multi-key proof at the branching level, one root hash. The PR stays draft until grovedb#793 merges and the pin moves to the merged rev.

…nge queries
A compound ranked index's leading properties can now carry at most one
IN where clause (2..=10 distinct elements, null legal for the
absent-value prefix) alongside equality pins, on both the ranked top-k
and having-range surfaces. Each element selects its own prefix branch;
the executors walk one axis secondary per branch with the full limit
and merge deterministically by (aggregate in walk direction, encoded
prefix segment ascending, group key in walk direction). Merged entries
carry an in_key discriminator - the encoded segment of their branch -
since one group key can legally appear under two prefixes.
Proofs stay per-branch: the proved response is a versioned container
of grovedb indexed-axis proofs in canonical branch order, and the
verifier re-derives the branch set from its own resolution, verifies
each branch against its own path, requires one root hash across
branches, and re-merges with the shared comparator - the merge itself
needs no proof because the merged page is a deterministic function of
independently proved branch pages (any union entry preceding a
returned entry is preceded within its own branch by fewer than limit
entries, so per-branch completeness composes). A single-element IN is
normalized to an equality pin and stays byte-identical to ==.
OFFSET is rejected together with IN (rank-skip is attested from one
secondary's counted commitments; no counted structure spans the
union). Wire: RankedEntry gains optional in_key (additive; clients
regenerated); no request-side changes. The branch ceiling is a hard
rejection like the limit ceiling, since the branch set is echoed in
the proof container.
Grammar, merge order (including a cross-prefix aggregate tie and a
null element mixed with a real one), the container tamper matrix
(reorder / drop / duplicate / re-version / pad), the degenerate
single-element equivalence, and the wire round trip are all pinned in
the drive and abci suites.

The one-IN budget was charged before checking whether the current
clause was a singleton, so `a IN [1,2] AND b IN [3]` rejected while
the reversed order passed. Only multi-element INs now count against
the budget, in either order — a singleton is an equality pin, as
documented. Both orders pinned in in_pin_shape_rejections.

…tainer
The IN-pinned prove and verify paths now use grovedb's branched
indexed-axis proofs (dashpay/grovedb#793): shared ancestor layers
appear once, the branching level is one multi-key Merk proof binding
every branch's value tree, each branch carries only its tail, and one
root hash is reconstructed for the whole envelope. The length-prefixed
container of per-branch proofs is deleted, along with the cross-branch
root-hash equality assertion it required; the platform keeps the merge
comparator, in_key tagging, and grove-path decomposition. grovedb pin
bumped to the PR branch.
The deep tamper matrix (reordered keys, duplicated or dropped tails,
echo mismatches) moved to grovedb's own suite where the envelope now
lives; the platform test pins corrupted and truncated bytes plus the
two envelope shapes never cross-verifying. Review fixes folded in:
encode_prefix_branches validates pin shape itself (non-empty values,
at most one branching pin), branch indexing fails closed instead of
panicking, and the no-covering-index and having-grammar docs describe
the IN-inclusive pin rule.

… error
prefix IN [existing, absent] previously aborted the whole request the
moment any selected prefix had no documents, losing the existing
branches' valid results - the advertised union semantics were
incomplete. Now an element whose prefix subtree was never created
contributes the empty page on both execution paths:
- Proved: grovedb's branched envelope authenticates the absence at the
branching level (the exact-key multi-key proof proves both presence
and absence), carries no tail for the absent branch, and rejects
absence forgery in both directions - claiming a present key absent
or grafting a tail onto an absent key both fail verification.
- Unproved: the executors check the branch key at the branching Merk
and treat a missing key as the empty branch, so proved and unproved
execution stay equivalent.
Presence is decided at the branching Merk itself: deeper breakage
under a present key stays an error, and the single-==-pin contract is
untouched (an unknown pinned value still errors rather than
fabricating an empty page; its test still pins that). grovedb pin
bumped to the absence-aware revision; round-trip coverage on both
surfaces via never-written IN elements.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The orphaned grovedb branch this feature was built against carried
bespoke `prove/verify_indexed_axis_*_branched` entry points; grovedb
develop landed the same capability as a query shape instead
(dashpay/grovedb#799): `PathQuery::new_branched_axis(prefix,
branch_keys, suffix, axis_query)` proved through the standard
`prove_query` and verified through `verify_path_query`, which returns
per branch key — in query order — the proved entries, or None for a
branch key whose absence the branching-level Merk proof authenticates
(the empty-branch reading the unproved path already gives an absent
`IN` element).
Both provers build that query from the same `decompose_branch_paths`
triple as before; both verifiers reconstruct it from the request, so
axis, k/bounds, limit, direction and the branch set are bound by
construction, and re-derive the page with the shared merge. The
verifiers additionally require the returned branch set to equal the
resolved one. The having bounds pass as inclusive i128 pairs
(`AxisRangeBounds::inclusive_bounds_i128`) matching
`AxisTraversal::Bounded`; entry mapping follows the canonical-reference
rows (`IndexedAxisEntry::key_pair`, grovedb #817).

Rebuilt on the unified PathQuery and rebased onto v4.2-dev (post-#4382, grovedb 753a11f1); the previous head was 44f23fc11b if anything needs recovering.

All five original commits are preserved; the new tail commit rewrites only the proof layer: the bespoke prove/verify_indexed_axis_*_branched entry points from the orphaned grovedb branch became PathQuery::new_branched_axis(prefix, branch_keys, suffix, axis_query) proved through the standard prove_query and verified through verify_path_query — per-branch authenticated absence (None = proven-absent branch = empty page) replaces the bespoke container, the verifiers additionally require the returned branch set to equal the resolved one, entry mapping follows the canonical-reference rows (grovedb #817), and the executors' unproved reads stay on the keys-only primitives. Verified locally: ranked+having 106/106 including the IN prove/verify roundtrips, drive-abci document-query 94/94, drive-proof-verifier 267/267, workspace check, clippy, fmt.

Preliminary review — Codex only

The unified branched proof envelope is well structured, and all four prior findings are fixed at the current head. Three blocking edge cases remain: absent suffix paths make proved and unproved execution disagree, legal null suffix pins cannot be proved, and multi-branch proof generation ignores the caller's transaction. Two in-scope documentation and API-boundary suggestions also remain.

- [BLOCKING] packages/rs-drive/src/query/drive_document_ranked_query/execute_top_k.rs:130-141: Check the full suffix before treating an IN branch as present
`branch_is_absent` checks only the varying branch key and ignores the shared suffix returned by `decompose_branch_paths`. For an index `[a, b, group]` queried with `a IN [A1, A2] AND b == B`, the `A2` tree can exist because it contains another `b` value while the requested `A2 / b / B / group` path is absent. This check then reports the branch as present, and `execute_top_k_no_proof_branch` errors while opening the missing terminal path, discarding valid results from `A1`. GroveDB's branched reader and prover instead treat a missing branch key or any missing suffix segment as an absent branch, so proof and non-proof execution disagree. The equivalent `branch_is_absent` implementation in `drive_document_having_query/execute_range.rs` has the same defect. Traverse the complete branch-key-plus-suffix chain, or use the transaction-aware branched keys reader, so any absent segment contributes an empty branch.
- [BLOCKING] packages/rs-drive/src/query/drive_document_ranked_query/execute_top_k.rs:300-316: Support empty suffix segments for legal null prefix pins
`encode_prefix_branches` intentionally represents a legal `null` pin with an empty path segment. When the branching `IN` is on an earlier leading property and a later equality pin is `null`, `decompose_branch_paths` places that empty segment in `suffix`. The pinned GroveDB implementation rejects `PathQuery::new_branched_axis` shapes whose suffix is empty or contains an empty key, so proof generation fails even though non-proof execution can read the indexed null-prefix path. The having-range prover constructs the same invalid shape. Either extend the GroveDB branched-axis grammar and proof implementation to support empty suffix keys, or reject this placement in the request grammar rather than advertising `null` as unconditionally legal.
- [BLOCKING] packages/rs-drive/src/query/drive_document_ranked_query/execute_top_k.rs:315-317: Branched proof generation ignores the supplied transaction
The multi-branch path calls `GroveDb::prove_query`, whose arguments are the `PathQuery`, proof options, and GroveDB version; it has no `TransactionArg`. The `None` passed here is a `ProveOptions` value, not the caller's transaction, and generic proof generation opens its own GroveDB transactions. The single-branch prover and both non-proof paths do use the supplied transaction. A caller querying uncommitted changes can therefore read the transactional branch state without a proof but receive a proof for committed state, fail to prove a branch created in the transaction, or reconstruct a root for the wrong snapshot. `drive_document_having_query/execute_range.rs:233-234` has the same regression. Add a transaction-aware `PathQuery` proof API or explicitly reject transactional multi-branch proving until one is available, with a regression test covering uncommitted branch data.

- [SUGGESTION] packages/rs-drive/src/query/drive_document_ranked_query/index_picker.rs:304-330: Enforce the branch ceiling in the public prefix encoder
`encode_prefix_branches` now enforces its nonempty and single-varying-pin invariants, but it does not enforce `MAX_PREFIX_IN_BRANCHES`. Because `PrefixPin` and this encoder are public, safe Rust callers can pass one pin containing arbitrarily many values and cause unbounded encoding, sorting, cloning, and branch construction despite the module documenting ten branches as a hard ceiling. Normal request parsing enforces the limit, so this is not a production-path blocker, but the public prover/verifier agreement boundary should enforce all downstream fan-out invariants itself.
In `packages/rs-drive/src/query/drive_document_ranked_query/mod.rs`:
- [SUGGESTION] packages/rs-drive/src/query/drive_document_ranked_query/mod.rs:41-54: Update IN and unified-proof documentation
These module docs still say that every prefix must use equality and that `IN` is a future capability, directly contradicting the behavior added by this PR. Other shipped documentation is stale as well: `book/src/drive/document-ranked-trees.md:344` still describes per-branch proofs in a container, and the rejected-shape descriptions in `platform.proto:904-905` still classify non-`EQUAL` prefix operators as unsupported. Update these descriptions to document one bounded branching `IN` and the unified branched `PathQuery` envelope.

…ns, transactional proves
Three review findings on the branched (IN-pinned) ranked/having surface:
- Absence is authenticated at ANY depth of a branch's chain, so the
unproved executors now walk the whole branch-key-plus-suffix chain
(`branch_subpath_is_absent`): an IN element whose value tree exists
via some other pin value but whose deeper pinned path was never
written is an empty branch, exactly as grovedb's branched reader and
prover treat it — not an error that discards the other branches.
- A single null pin combined with an IN is rejected at the shared
encoder: null addresses its prefix through an empty path segment the
branched proof grammar cannot express, so serving it unproved while
the prove fails would be a proved/unproved divergence. null as an
ELEMENT of the IN stays legal — it is a branch key the envelope
addresses and authenticates like any other (pinned by the existing
mixed-null having test).
- grovedb's unified prove_query proves committed state only (it opens
its own transaction), so a branched prove under a caller transaction
fails closed with NotSupported on both surfaces instead of silently
proving a different snapshot than the unproved read serves.
Also per review: encode_prefix_branches enforces MAX_PREFIX_IN_BRANCHES
itself (it is pub and the fan-out hangs off it), and the module docs and
book row now describe the shipped IN semantics and the unified branched
PathQuery envelope. New dualGrade fixture doctype ([identityId, tag,
class]) exercises the two-leading-property cases; four regression tests.

Preliminary review — Codex only

The unified branched proof path correctly handles authenticated deep absence, null-placement rejection, and transactional proof rejection. One blocking consistency issue remains in unproved multi-branch reads, while the public encoder ceiling, unnecessary branch-helper exposure, and stale IN/proof documentation remain suggestions.

- [BLOCKING] packages/rs-drive/src/query/drive_document_ranked_query/execute_top_k.rs:79-104: Pin all unproved branch walks to one GroveDB snapshot
The multi-branch read performs each absence probe and each branch walk as a separate GroveDB operation while forwarding `None` from the production ABCI dispatcher. Each operation then creates its own transaction or iterator view, so a block commit between calls can merge branch pages that never coexisted in one committed state. `drive_document_having_query/execute_range.rs:47-61` has the same issue. The DAPI committed-height guard normally retries across a concurrent commit, but it does not itself pin the reads and there is a post-commit/pre-guard-update window; direct Drive callers also have no such guard. Execute the complete branched read against one explicitly pinned read snapshot, or add/use a GroveDB branched keys-read primitive that owns one snapshot across all absence checks and axis walks. Merely reusing GroveDB's default optimistic transaction is insufficient unless that transaction is configured to provide repeatable snapshot reads.

This PR exports the new `branches` module even though every workspace use is internal to `rs-drive`. Its low-level helpers accept raw vectors and rely on resolver-established invariants; for example, `merge_branch_pages` documents matching branch/page cardinality but does not enforce it, so a safe external caller can silently omit branches or merge extra pages without a valid `in_key`. Keep these mechanics crate-private, or expose a validated branch-set type if downstream use is intended.

Additional stale references remain at `drive_document_ranked_query/mod.rs:147`, which says the branch set is echoed in a proof "container" although the implementation emits one unified branched `PathQuery` envelope, and at `index_picker.rs:30`, which links to the removed `equality_pins_from_where_clauses` symbol. Reconcile these descriptions with the shipped grammar and proof format.

(existing thread: https://github.com/dashpay/platform/pull/4401#discussion_r3845579042)
The encoder now rejects a result exceeding `MAX_PREFIX_IN_BRANCHES`, but it does so only at lines 373-384 after every candidate has been encoded and sorted and the full branch vector has been cloned and constructed. Although request parsing protects the first-party DAPI path, `encode_prefix_branches` and `PrefixPin` are public, so a downstream caller can still cause unbounded CPU and allocation before receiving the ceiling error. Reject any pin whose candidate count exceeds the ceiling before constructing `per_property`; retain the final branch-count check as a backstop.

Comment threadpackages/rs-drive/src/query/drive_document_ranked_query/mod.rs Outdated
The unproved multi-branch read performed each absence probe and each
branch walk as its own GroveDB operation, so a block commit landing
between calls could merge branch pages that never coexisted in one
committed state. Both executors now issue ONE grovedb call — the same
`PathQuery::new_branched_axis` the prover builds, run through
`run_path_query` with the keys-only projection — so every absence
decision and every branch page comes from a single snapshot, absence at
any depth is the branched reader's empty branch, and the caller's
transaction reaches the read end-to-end (regression test: a branch
written only inside a transaction is visible through it and
authenticated absent without it). The per-branch loop, the absence
probes and the chain-walk helper are gone.
Also per review: `branches` is crate-private; `encode_prefix_branches`
rejects oversized pins BEFORE any encoding work (the post-product count
stays as a backstop); the platform.proto rejected-shape bullets, the
"proof container" wording and a dead doc link now describe the shipped
IN grammar and the unified branched envelope (no checked-in generated
file embeds the old proto text, so no client regen is triggered).

Preliminary review — Codex only

The unified branched read still does not provide the single-snapshot guarantee claimed by the latest commit: with the production None transaction, the pinned GroveDB implementation creates independent transaction or iterator views for its nested suffix probes and branch walks. The branch encoding, API visibility, and specifically identified proof documentation issues are fixed, although several remaining comments still contradict the new deep-absence and bounded-IN semantics. Source: Codex reviewer backend model gpt-5.6-sol (general, security-auditor, and Rust-quality lanes); final verifier backend model gpt-5.6-sol. openclaw-agent/cliproxy/gpt-5.6-sol is orchestration-only and not reviewer evidence.

Validated blockers were found in the Codex precheck. Opus is deferred until a fresh Codex revalidation clears the blocker gate.

- [BLOCKING] packages/rs-drive/src/query/drive_document_ranked_query/execute_top_k.rs:107-115: Pin all unproved branch walks to one GroveDB snapshot
(existing thread: https://github.com/dashpay/platform/pull/4401#discussion_r3850802892)
One `run_path_query` invocation does not make the complete union a single-snapshot read at the pinned GroveDB revision. Its `BranchedAxisRead` arm loops over branches and suffix segments, forwarding `transaction` separately to `get_raw_optional` and `run_axis_read` (`grovedb/src/operations/get/run_path_query.rs:267-318`). With the production ABCI callers passing `None`, every optional lookup creates a fresh owned transaction through `TxRef::new`, and every keys-only axis read creates another transaction before opening its iterator. A commit can therefore land between a suffix probe and that branch's walk, or between different branch walks, yielding a merged result assembled from states that never coexisted. The same defect affects `drive_document_having_query/execute_range.rs:66-74`. The new regression test only demonstrates forwarding of an explicitly supplied caller transaction; it does not exercise concurrent committed-state reads through the production `None` path. GroveDB must hold one explicitly snapshot-pinned read context across every absence check and axis walk; merely consolidating the calls into one Rust method, or hoisting a default snapshotless optimistic transaction, is insufficient.

Comment threadpackages/rs-drive/src/query/drive_document_ranked_query/execute_top_k.rs Outdated
…nd the branched envelope
Per review: the executor doc no longer calls a missing path under a
present branch key an error (it is the empty branch, at any depth);
the book's compound-prefix paragraph, both request structs'
`where_clauses` comments and the shared path-builder docs admit the
single bounded `IN` alongside equality pins; the ABCI wire test names
the unified branched `PathQuery` envelope instead of a container. The
round-3 executor comments also no longer claim a storage-level
snapshot for `None` reads: grovedb has no snapshot-pinned read
primitive, so the comment now states the actual model — one grovedb
call under the caller's transaction, DAPI's committed-height guard
operationally, and `prove = true` for authenticated cross-branch
consistency.

…rding, test strengthening
Per review: the wire contract, the book row, the ranked module docs and
the mirrored Objective-C client comment now state that a single-element
IN normalizes to the equality pin, and that it is a NON-ZERO offset
that is rejected together with IN (OFFSET 0 is the offset-free request
— rejecting it would contradict the pinned absent-offset equivalence,
so the docs follow the guard rather than the guard tightening). The
singleton-IN test now reads the IN spelling too and requires
byte-identical pages; the transactional-prove test's follow-up read is
described as the committed read it is; the renamed having test's doc
describes branch merging instead of the old rejection. The Objective-C
header's grammar block is hand-synced with the proto comment it embeds
(comment-only divergence left over from the earlier proto edit).
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The single branched grovedb call is not yet a single-snapshot read at
the pinned grovedb revision: its branched arm forwards the caller's
TransactionArg to each per-branch suffix probe and each axis walk, so
the production None path opens one implicit transaction per operation
- and even a hoisted optimistic transaction would not pin a snapshot,
since its reads see latest committed state. A block commit landing
inside the call could still merge branch pages from states that never
coexisted.
Both surfaces' multi-branch reads therefore run inside a root-hash
bracket - optimistic concurrency validation: read the committed root
hash, run the whole union, re-read the hash, accept only an untorn
window. Equal endpoint hashes mean no commit interleaved (every
Platform commit advances monotonic block metadata, so a window cannot
tear back to a byte-identical root), which is the same guarantee a
pinned snapshot would give, delivered by detection rather than new
storage-layer machinery. A torn window is discarded whole - its page
or error may both be artifacts of the tear - and retried; persistent
churn fails closed after three windows with the new retryable
DriveError::ConcurrentStateChurn instead of looping. Deterministic
regression tests drive commits into the window through the production
None path: one tear retries and serves the stable window, endless
tears exhaust the budget and fail closed.

Preliminary review — Codex only

The root-hash bracket detects an A→B change, but it still accepts an A→B→A window and therefore does not guarantee that every branch was read from one committed state.

Fixed in 71c3630da5 + grovedb ad012ded (dashpay/grovedb#831) with the storage-level snapshot-pinned read context: grovedb gains start_snapshot_read_transaction() — an optimistic transaction with a snapshot requested at creation, and both prefixed transaction contexts now inject that snapshot into every get's and raw iterator's ReadOptions (a plain transaction's null snapshot handle leaves reads on latest committed state, so existing callers are byte-for-byte unaffected). Both branched executors run their single branched call under one such transaction whenever the caller supplies none, so every per-branch absence probe and axis walk reads ONE RocksDB snapshot — the guarantee itself, not a validation of it. The root-hash bracket, its retry budget, and ConcurrentStateChurn are deleted; you were right that put_aux-persisted platform state defeats the monotonic-root premise. Pinned by a_branched_read_is_pinned_to_one_committed_state (platform: a commit creates a new branch and a new group between snapshot and read — the snapshot read returns the pre-commit union, absence included; a committed read the post-commit union) and snapshot_read_transaction_pins_a_branched_read_to_one_committed_state (grovedb, exercised through the branched arm itself, against a plain transaction and a None read).

Closed in 8ac1d7ecb9 via your third option: a caller-supplied transaction on a branched unproved read now fails closed with NotSupported, mirroring the branched provers — an ordinary grovedb transaction reads latest-committed per operation and cannot be told apart from a snapshot-pinned one at this boundary, so forwarding any caller transaction would reopen the tear. The union always runs under the internal snapshot read transaction. Per-element reads keep the transactional capability exactly (a single-pin read is one grovedb operation and serves the transaction's own writes), pinned by the rewritten a_branched_unproved_read_rejects_an_ordinary_transaction, which also asserts the committed None branched read is unaffected.

The root-hash bracket could not prove its own premise: platform state
bytes persist via put_aux OUTSIDE the authenticated root, so an
A->B->A window (a commit and its exact revert inside the read) keeps
the endpoint hashes equal while the branches were read from B. The
bracket, its retry budget, and DriveError::ConcurrentStateChurn are
deleted.
In their place, grovedb (pin ad012ded, dashpay/grovedb#831) gains
snapshot-pinned read transactions: start_snapshot_read_transaction()
begins an optimistic transaction with a snapshot requested, and the
prefixed transaction contexts route every get and raw iterator
through read options carrying that snapshot (a plain transaction's
null snapshot handle leaves reads on latest committed state, so
existing callers are unaffected). Both branched executors now run
their single branched call under such a transaction whenever the
caller supplies none, so every per-branch absence probe and axis walk
reads ONE RocksDB snapshot - the storage-level guarantee, not a
validation of it. A caller transaction is still used as-is.
Regression test a_branched_read_is_pinned_to_one_committed_state
commits a new branch and a new group between snapshot and read: the
snapshot read returns the pre-commit union (absence included), the
committed read the post-commit union. grovedb-side pinning is tested
at the pin (snapshot_read_transaction_pins_a_branched_read_to_one_committed_state).
Also per review: detect_ranked_mode_v0's public contract and the
prefix-pin helper intro now describe the bounded IN, branch merge and
non-zero-offset rejection, and the having executor's doc
distinguishes deep absence on branched reads from the single-pin
missing-path error.

Per review: the ranked and having-range executors duplicated the whole
branched-read sequence (path decomposition, branched PathQuery,
snapshot-transaction selection, run-shape and branch-set checks,
per-branch cap, merge), differing only in the AxisQuery and the cap.
Proof/read equivalence depends on the copies staying identical, so the
sequence now lives once in branches::read_branched_union and both
executors call it.
Also per review: the last "branch container" wording in both test
suites now names the branched PathQuery envelope, and the book row no
longer states the non-zero-OFFSET rejection twice.

Preliminary review — Codex only

The bounded-IN grammar, canonical branch merge, and unified proof shape are coherent, but two snapshot-consistency gaps remain: caller-supplied ordinary transactions can still tear unproved branch unions, and recursive proof generation can combine layers from different committed states. The remaining public documentation and snapshot-selection regression test also need alignment with the implemented behavior.

The branched proof path calls `GroveDb::prove_query`, which has no transaction argument. At the pinned GroveDB revision, `prove_subqueries_v1` creates a fresh ordinary `start_transaction()` at every recursive layer, and ordinary transactions read the latest committed state rather than a snapshot.

The test documentation says it protects the production `None` path that creates a snapshot internally, but the test creates `snapshot_transaction` itself and passes `Some(&snapshot_transaction)`. It therefore proves only that a caller-supplied snapshot is forwarded correctly. Removing the `transaction.is_none()` snapshot-selection branch from `read_branched_union` would leave this regression green. Add deterministic synchronization around snapshot creation and the concurrent commit, then issue the request with `None` so the test directly protects Drive's automatic snapshot selection.

(existing thread: https://github.com/dashpay/platform/pull/4401#discussion_r3853558584)
The helper creates a snapshot transaction only when `transaction.is_none()`. When a caller supplies an ordinary transaction, it forwards that transaction unchanged through the complete branched read. At the pinned GroveDB revision, `start_transaction()` explicitly reads the latest committed state on every operation; only `start_snapshot_read_transaction()` pins reads. GroveDB's `BranchedAxisRead` performs multiple suffix probes and axis walks, so a concurrent commit can move the transaction's committed base between those operations while preserving its own uncommitted writes. The resulting union can contain branch pages that never coexisted in one state. This path is part of the accepted public operation and is exercised by `a_branched_unproved_read_honors_the_transaction`, which passes an ordinary `start_transaction()`. Require a snapshot-aware caller transaction, provide a snapshot/read-your-own-writes context, or reject ordinary supplied transactions for branched reads.

🔴 Blocking: Generate every branched proof layer from one snapshot

The branched proof path calls GroveDb::prove_query, which has no transaction argument. At the pinned GroveDB revision, prove_subqueries_v1 creates a fresh ordinary start_transaction() at every recursive layer, and ordinary transactions read the latest committed state rather than a snapshot. A commit between the branching-level proof and a branch's indexed-axis proof can therefore combine layers from states that never coexisted. Verification will reject the resulting hash chain, so a normal concurrent block commit can make the node return an unusable proof. The having-range prover has the same issue at drive_document_having_query/execute_range.rs:227-229. Add a GroveDB proof API that threads one snapshot-pinned transaction through the full recursive proof generation and use it on both branched surfaces.

Fixed in 8ac1d7ecb9 + grovedb cbcb3b59 (dashpay/grovedb#831): both prove_query entry points (V0 and V1) now begin ONE snapshot read transaction and thread it through the entire recursive generation — prove_subqueries/prove_subqueries_v1 and the count-offset target check take the threaded transaction instead of opening their own — so every layer (shared ancestors, the branching level, each branch's axis descent) reads the same committed state and a concurrent commit can no longer produce a proof whose layers fail to hash-chain. Proof bytes for any single committed state are unchanged; both branched surfaces get this through the same prove_query call. The full grovedb suite (2915) passes with the threading.

🟡 Suggestion: Exercise automatic snapshot selection in the regression test

The test documentation says it protects the production None path that creates a snapshot internally, but the test creates snapshot_transaction itself and passes Some(&snapshot_transaction). It therefore proves only that a caller-supplied snapshot is forwarded correctly. Removing the transaction.is_none() snapshot-selection branch from read_branched_union would leave this regression green. Add deterministic synchronization around snapshot creation and the concurrent commit, then issue the request with None so the test directly protects Drive's automatic snapshot selection.

Fixed in 8ac1d7ecb9: the regression now exercises the production None path itself. A test-only seam (branches::test_hooks::AFTER_BRANCHED_SNAPSHOT) fires after the executor takes its internal snapshot and before the branched call runs; the test installs a rendezvous there, a scoped writer thread lands the commit (new branch + changed page) deterministically inside the window, and the request is issued with None — the read must return the pre-commit union, so deleting the automatic snapshot selection in read_branched_union fails the test.

…tions on branched reads
Two snapshot-consistency gaps from review, closed at their sources:
Proof generation: grovedb's recursive provers opened a fresh ordinary
transaction per layer, so a commit landing mid-generation combined
layers from states that never coexisted - the hash chain then fails
every verifier, making proof generation spuriously fail under normal
block traffic. grovedb (pin cbcb3b59, dashpay/grovedb#831) now begins
ONE snapshot read transaction at each prove_query entry (V0 and V1)
and threads it through the entire recursion, so every layer - shared
ancestors, the branching level, each branch's axis descent - reads one
committed state. Proof bytes for any single state are unchanged.
Unproved branched reads: a caller-supplied ordinary transaction reads
the latest committed state on every operation, so forwarding it
through the multi-operation branched arm could tear the union - and an
ordinary transaction cannot be told apart from a snapshot-pinned one
at this boundary. Branched reads under a caller transaction now fail
closed (mirroring the branched provers); per-element reads keep the
transactional capability exactly (a single-pin read is one grovedb
operation), pinned by the rewritten rejection test.
The one-committed-state regression now exercises the production None
path itself: a test-only seam fires after the executor takes its
internal snapshot, a scoped writer thread lands the commit inside the
window, and the None read must return the pre-commit union - deleting
the automatic snapshot selection fails the test.
Also per review: DocumentRankedMode/DocumentHavingMode prefix_pins
docs and both resolvers now describe PrefixPins (one value normally,
several for the single branching IN) instead of equality pairs.

clippy 1.92's items_after_test_module (a warning locally, an error
under CI's -D warnings) forbids items after a #[cfg(test)] module; the

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

All four previously verified findings are fixed at the exact head: branched reads reject caller transactions and use an internal snapshot, GroveDB proof generation threads one snapshot through every recursive layer, the public prefix-pin documentation is aligned, and the regression now exercises automatic snapshot selection. The only remaining in-scope issue is the absence of a deterministic concurrent-commit regression for snapshot-pinned recursive proof generation.
Source: Codex reviewer backend model gpt-5.6-sol (general, security-auditor, and rust-quality); final verifier backend model gpt-5.6-sol. openclaw-agent/cliproxy/gpt-5.6-sol is orchestration-only and not reviewer evidence.

Added in ca50ce6aed (grovedb fa6c85cf, dashpay/grovedb#831 — test-only delta): a seam now fires in both prove_query entries right after the generation snapshot is taken, and proof_generation_is_pinned_to_one_snapshot_across_a_concurrent_commit lands a commit deterministically inside that window through a scoped writer thread — a new branch springs into existence and an existing page changes — then requires the branched envelope to still verify against the PRE-commit root with the pre-commit content, authenticated absence included. A regression to independent per-layer views would build the proof from post-commit state and fail the root assertion. The branched shape exercised is the common grovedb primitive both ranked and having-range proves go through, exactly as suggested.

🤖 Addressed by Claude Code

Per review: the snapshot threading through recursive proof generation
had no concurrency regression - a regression back to per-layer views
would have stayed green. grovedb fa6c85cf adds a test-only seam fired
in both prove_query entries right after the generation snapshot is
taken, and a test that lands a commit inside that window through a
scoped writer thread and requires the branched envelope to still
verify against the PRE-commit root with the pre-commit content,
absence included - the common primitive both IN-pinned surfaces prove
through. Test-only grovedb delta; no platform code change.
