Preliminary review — Codex only
The pagination fix is protocol-gated and has strong regression coverage for both the corrected v14 behavior and frozen v13 outputs. However, the new consensus-relevant method slot is consumed through inline >= 1 checks rather than exact version dispatch, so unsupported versions silently inherit v1 behavior and the implementations are not independently frozen.
Source: reviewer backend model gpt-5.6-sol; final verifier backend model gpt-5.6-sol. Orchestration-only model openclaw-agent/cliproxy/gpt-5.6-sol is explicitly 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/mod.rs:1954-1960: Dispatch the lowering through exact method versions
`non_primary_key_path_query` is a new consensus-relevant method-version slot, but this check and the second `>= 1` check at lines 2230–2236 embed v0/v1 selection inside the existing recursive implementation. An unsupported future value such as `2` therefore executes v1 instead of returning an unknown-version error, which can hide an incomplete or inconsistent platform-version table. It also leaves the released v0 behavior interwoven with code that future changes can modify accidentally. Route the entry point through an exact match (`0 => v0`, `1 => v1`, unknown => `DriveError::UnknownVersionMismatch`) and keep the version-specific lowering implementations separately frozen.

Resolved by the rebase onto #4391 plus a follow-up commit. The inline >= 1 checks this comment pointed at no longer exist:
get_non_primary_key_path_querynow dispatches through an exact match on the slot (0 => v0,1 => v1, unknown =>DriveError::UnknownVersionMismatchwithknown_versions: [0, 1]), as doesvalidate_in_clause_shape, the only other read of the slot.- The released v0 lowering lives untouched in
query/non_primary_key_path_query/v0/; the v14 changes are isolated inv1/and its shape submodules, so future edits can't accidentally modify v0. Thetest_family_single_in_clause_with_cursor_v0_lowering_frozen_at_protocol_v13freeze test additionally pins v0's outputs byte-for-byte on both the execution and proof paths. - As of 5882f9f the two shape lowerings are themselves versioned methods behind their own slots (
non_primary_key_single_in_path_query,non_primary_key_multiple_in_path_query), each with the same exact-match-or-error dispatch and a frozenv0module owning its recursion helpers.
… sibling-branch documents For a document query with a single In (or range) clause, leftover index properties, and startAt/startAfter, the path-query lowering baked the cursor document's per-level start keys into the default subquery applied to every sibling branch of the multi-branch level. Branches ordered after the cursor's branch silently dropped all values below the cursor key, and branches ordered before it wrongly included values above it. The lowering also ignored a descending orderBy on leftover index properties for cursorless queries, returning within-branch results in index (ascending) order. From v1 of the new DriveDocumentQueryMethodVersions.non_primary_key_path_query method version (protocol v14, unreleased): - branches ordered before the cursor's branch are trimmed from the outer query; - branches ordered after it get an unfiltered default subquery; - the cursor's own branch is refined with a conditional subquery at its branch key (the design the existing block comment already described); - the cursorless lowering derives each level's direction from orderBy instead of the index property's own direction. v0 behavior is preserved for released protocol versions, since the lowering is shared by the prover and verifier and is part of the consensus query contract.

Protocol versions <= 13 are on chain, so the pre-v14 (defective) cursor lowering must replay byte-for-byte. Pin its outputs for the same scenarios the v14 fix corrects, on both the execution and proof paths, and assert protocol v13 selects method version 0.

…version slots The v1 non-primary-key lowering routed by shape to two unversioned worker methods. Give each shape lowering the standard versioned-method structure: get_non_primary_key_single_in_path_query and get_non_primary_key_multiple_in_path_query dispatch through new DriveDocumentQueryMethodVersions slots (0 in every table) to frozen v0 modules holding the constructions and their recursion helpers, so a future change to one shape bumps that slot alone instead of copying the whole v1 lowering. Unknown slot values error with UnknownVersionMismatch. No behavior change. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Cursor pagination (
startAt/startAfter) over a document query whose best index level is multi-branch — a singleInclause (or a range clause) with leftover index properties — returned wrong result sets:Example (family contract, index
[firstName, lastName]):firstName IN [Adam, Ben, Cara] ORDER BY firstName, lastNamewithstartAftera document(Adam, Moore)dropped(Ben, Barber)and(Cara, Abbott).The cause: the v0 lowering builds the outer multi-branch level with no cursor awareness and then
recursive_insert_on_querybakes the cursor's per-level start keys into the default subquery applied to every sibling branch. The block comment in that function ("the start at document is used only on the conditional subquery and not on the main query") already described the correct construction; the code didn't implement it at the multi-branch top level.A second latent defect surfaced while testing the reversed direction: for cursorless queries, the leftover-level recursion built each level with the index property's own direction, ignoring an opposite-direction
orderBy—orderBy [lastName, desc]on a leftover property returned within-branch results ascending. All existing desc-on-leftover tests used cursors, which route through a different (direction-correct) arm, so this was never caught.This is the machinery that led #4391 to reject
startAt/startAftercombined with multipleInclauses.What was done?
Rebased over #4391 (merged), which introduced the shared
DriveDocumentQueryMethodVersions.non_primary_key_path_queryslot and thequery/non_primary_key_path_query/{v0,v1}module split. Both PRs' v14 semantics now live under that one slot, as planned when the slot name was deliberately shared.The v1 lowering (protocol v14, unreleased) now only routes by shape: both shape lowerings are versioned methods with their own
DriveDocumentQueryMethodVersionsslots (non_primary_key_single_in_path_query,non_primary_key_multiple_in_path_query, 0 in every table, exact-match dispatch erroring on unknown values) and frozenv0modules. The new at-most-one-Inlowering,single_in_path_query/v0, replaces v1's previous fallthrough to the pre-v14 lowering for those shapes. When the last clause is range-typed with leftover index properties and a cursor is present:insert_all, direction derived fromorderBy), so branches after the cursor return everything;The cursor-recursion helpers live beside their owner in
single_in_path_query/v0asrecursive_insert_on_query_ordered_with_cursor/recursive_conditional_insert_on_query_ordered/recursive_create_query_ordered, identical to their pre-v14 counterparts except that every cursorless level derives its direction fromorderBy(falling back to the index property's own) — the same rule #4391'srecursive_insert_on_query_orderedapplies on the multi-Inpath, so v1 direction semantics are uniform. The v0 module is untouched, per the frozen-version-module convention.Not covered (still v0-shaped inside v1, same bug family, can be follow-ups): the
In+ range combination (subquery_clausepath) with a cursor, and the no-where-clause path (orderBy-only with a cursor and leftover properties).How Has This Been Tested?
New integration test
test_family_single_in_clause_with_cursor_keeps_sibling_branches_intact(rs-drivetests/query_tests.rs) with a fixed 7-person dataset (newsetup_family_tests_with_peoplehelper) and brute-force expected orderings. Five scenarios — page-one asc and desc, cursor in the first branch, cursor in a middle branch, and a descending cursor — each asserted on both the no-proof execution path and the proof path (proof results must byte-match, root hash checked). The test fails on the v0 lowering exactly as described and passes with the fix.A second test,
test_family_single_in_clause_with_cursor_v0_lowering_frozen_at_protocol_v13, runs the same scenarios atPlatformVersion::get(13)and pins the old defective outputs on both execution and proof paths, plus asserts protocol v13 selects method version 0 — proving the gate empirically in both directions (v14 fixed, ≤v13 byte-for-byte frozen).Regression: full
cargo test -p drive(3336 lib tests plus all integration suites, including #4391's new multi-Intests) green; rs-drive compiles with--no-default-features --features verify; clippy clean on both touched crates (--all-targetsand--all-features --tests); drive-abcidocument_querytests green.Breaking Changes
Result sets and ordering of accepted-and-answered document queries change for the shapes above. The change only activates at protocol v14 via
non_primary_key_path_query: 1(shared with #4391's multi-Insupport); all released protocol versions retain the v0 lowering.Checklist:
