📝 WalkthroughWalkthroughRanked and HAVING queries now support one bounded multi-value ChangesRanked-index IN branching
Estimated code review effort: 4 (Complex) | ~60 minutes Mergeability Score: 🟡 Moderate · up to This change adds multi-branch IN queries with client-side merging and proof verification. Invalid or internally constructed query shapes can currently produce incorrect branch identity, invalid rank windows, or runtime panics, so merge should wait for the branch and merge invariants to be enforced consistently.

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 |

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.
Source: reviewer backend model gpt-5.6-sol; 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: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.
In `packages/rs-drive/src/query/drive_document_ranked_query/path.rs`:
- [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 comment says every clause is an equality and then says one of those clauses may be `IN`. State the actual grammar directly: each clause is an equality except that at most one clause may be a branching `IN`.

The outside-diff finding (stale "equality where clause" wording in 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.

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).

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. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

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.

In `packages/rs-drive/src/query/drive_document_ranked_query/execute_top_k.rs`:
- [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.
In `packages/rs-drive/src/query/drive_document_ranked_query/mod.rs`:
- [SUGGESTION] packages/rs-drive/src/query/drive_document_ranked_query/mod.rs:93-94: Keep resolver-only branch mechanics out of the public API
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.
In `packages/dapi-grpc/protos/platform/v0/platform.proto`:
- [SUGGESTION] packages/dapi-grpc/protos/platform/v0/platform.proto:903-905: Update IN and unified-proof documentation
The accepted-shape descriptions at lines 896 and 900 permit one bounded prefix `IN`, but the rejected-shape bullets still describe equality-only prefix pins and reject every non-`EQUAL` operator. 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.
In `packages/rs-drive/src/query/drive_document_ranked_query/index_picker.rs`:
- [SUGGESTION] packages/rs-drive/src/query/drive_document_ranked_query/index_picker.rs:247-248: Enforce the branch ceiling in the public prefix encoder
(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.
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).

Compound ranked indexes (#4393) require every leading property pinned with
==, so "rank classes for these three identities" takes three requests. TheINrejection 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?
prefix_pins_from_where_clauses, shared by both surfaces): at most oneINacross the leading prefix properties, 2..=10 distinct elements (MAX_PREFIX_IN_BRANCHES, a hard rejection like the limit ceiling),nulllegal (addresses the absent-value / empty-segment prefix), single-elementINnormalized to==.OFFSETis rejected together withIN— rank-skip is attested per-secondary and has no meaning across a branch union.encode_prefix_branchesproduces 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 carryprefix_branches; single-branch requests are byte-identical to before.(aggregate in walk direction, encoded prefix ascending, group key in walk direction). Merged entries carryin_key(the branch's encoded segment) since one group key can appear under two prefixes.branches.rs).RankedEntrygains optionalin_key(additive; all clients regenerated).
