Context

PR 4 of the unified PathQuery effort (stacked on #798#797#795) — the full-integration step the effort was pointed at: a PathQuery whose query node carries ReadMode::Axis now proves and verifies through the general V1 proof walk, via a new appended ProofBytes::IndexedTreeAxisDescent variant whose payload carries a proof over the queried per-axis secondary in place of the primary descent.

Design

Query-as-input, no echoes. The payload carries no traversal parameters — the verifier resolves axis, bounds, direction, and caps from the query it independently holds, through the new PathQuery::axis_read_at_path (the same resolver the prover uses, so prover and verifier cannot disagree about which layers are axis reads). One exception: RankOfKey carries the prover-computed rank, required to drive the count-offset verification walk — the count commitments attest it, and the single yielded entry must be the queried key.

Recomputed attestation. Where the primary-descent shape (ProofBytes::CountIndexedTree) supplies the 32-byte secondary-root attestation raw (safe there because it enters the combine_hash_three preimage), the axis descent recomputes it from the carried secondary proof, then rebuilds the third combine input — the recomputed root for PCIT/PSIT, or axes_digest(other_axes + recomputed queried-axis root) for PCPSIT, family-checked against axis-relabel forgery — and requires the parent-committed value_hash to match. primary_root_hash / other_axes_root_hashes remain prover-supplied but bound: forging either fails the binding.

Branched = the ordinary walk. Branch keys are Key items at the branching layer (one multi-key merk proof; absence proven natively by merk), each present branch descends the shared suffix to its own axis-descent terminal, and shared-prefix layers are naturally deduplicated by LayerProof nesting. The verifier rejects a proof that shows a branch key present while omitting its axis layer — hiding entries behind fake absence fails closed.

Surface.

  • prove_query serves axis shapes (V1 envelope only; V0 refusal follows the ACOR template)
  • verify_path_query (new, verify-feature-reachable): the unified verify entry returning a typed VerifiedPathQuery for every provable shape — key selection, all six aggregate forms, axis entries / rank / range-aggregate, and branched with authenticated absence. The verify_query family stays key-selection-only.
  • New proof.axis_descent_in_v1_envelope slot (0 in V1–V3, 1 in V4), read by both sides: below V4 the prover refuses and the verifier rejects, mirroring the fail-closed version-2 Query decode.
  • The rank computation and the attestation-binding core are factored out of the standalone-envelope machinery (compute_indexed_axis_rank_of_key, recompute_axis_binding_digest) and shared — one copy of the consensus-relevant logic, not two. The standalone envelopes and their ~26 entry points are untouched and remain first-class.

Tests

  • Round trips: top-k, paginated (attested skip), bounded (shared lowering, successor-exclusive upper bound), rank in both directions, range aggregate; PCPSIT three-axis digest reconstruction; branched with a present/absent branch mix.
  • Cross-checks: verified entries ≡ trusted reads ≡ standalone-envelope results, with matching reconstructed root hashes.
  • Forgeries (all rejected): forged primary_root_hash; relabeled axis_tag; tampered secondary-proof bytes; smuggled other_axes on a single-secondary target; lying rank echo; stripping a present branch's descent to fake absence.
  • Gates: V3 prover refuses, V3 verifier rejects a genuine V4 proof, V0 envelope + axis query rejected; verify_path_query also round-trips plain key selection.
  • Full grovedb suite green (2600+ tests), clippy clean, --no-default-features --features verify build green.

Review focus

The consensus-adjacent surface is verify_axis_descent_layer (verify.rs) and the axis_read_at_path resolver — an adversarial pass on those two is the highest-value review. A dedicated security-audit pass is being run and its findings will be posted on this PR.

This is Claude. A dedicated adversarial security audit ran against this PR's diff (blockchain-security-auditor pass, as promised in the description). Results:

Two real findings, both now fixed in c6b2283e with regression tests:

  1. Branched absence forgery (Medium) — the axis-read check sat inside the lower-layer lookup, so stripping the axis-descent layer of a branch whose indexed tree exists but is empty (is_non_empty_tree() is false for it, so no existing guard fired) let a prover obtain a verified None ("proven absent") slot under the genuine root hash. Fixed by hoisting the axis check above the lookup: at an axis-read position a missing layer is now a hard InvalidProof, and an existing empty indexed tree reports Some(empty entries) — matching the honest prover and the trusted read. The branched absence guard in verify_path_query also widened to reject any present trio under the branch subtree, and run_path_query's branched read now resolves the full suffix chain so read and proof agree on None at every absence level.

  2. Bounded traversal vs empty secondary (Medium, liveness)Merk::prove refuses empty trees, so a bounded axis proof over a freshly created indexed tree hard-errored while every other traversal (and the trusted read) handled it. Both sides now use the same empty convention as count-offset and aggregate-on-range: empty proof bytes ⇒ NULL_HASH secondary root, accepted only when the element genuinely commits an empty secondary.

  3. Duplicate branch keys (Low)classify() now rejects a branched read naming the same branch key twice (a valid proof could otherwise yield contradictory Some/None rows for one key).

Confirmed defended (with defending lines traced): forged primary_root_hash, relabeled axis_tag (both the tag check and the element-family check), tampered secondary bytes (root recomputed), smuggled other_axes on single-secondary targets, PCPSIT axes reorder/dup (sorted-strict tag check + length-prefixed axes_digest), lying/overflowing rank echoes (checked_add + count commitments + yielded-key check), single-path layer stripping and path spoofing, axis payloads at non-axis positions (three arms), nested layers under a descent, prover/verifier resolver divergence (single shared axis_read_at_path, conditional branches unreachable by grammar), envelope downgrades (three coordinated gates), decode DoS (16MiB payload cap, ≤256 axes, depth caps), and zero behavior change to the LOCKED V0 path and existing V1 key selection.

One documented non-issue: the bounded secondary executes with the lenient proof version, matching the standalone envelope; safe because the axis decoders consume only proof keys (bound into the recomputed root), never values — now stated in a code comment so a future value-consuming change doesn't inherit it silently.

The full-integration step: a PathQuery whose query node carries
ReadMode::Axis now proves and verifies through the general V1 proof
walk, via a new appended ProofBytes::IndexedTreeAxisDescent variant
whose payload carries a proof over the queried per-axis SECONDARY in
place of the primary descent.

Trust model. The payload echoes no traversal parameters (the V1
envelope's query-as-input philosophy — the verifier resolves the axis,
bounds, direction, and caps from the query it independently holds, via
the new PathQuery::axis_read_at_path, the same resolver the prover
uses, so the two sides cannot disagree about which layers are axis
reads). The verifier RECOMPUTES the secondary-root attestation from the
carried secondary proof — never accepting 32 raw bytes — then rebuilds
the third combine_hash_three input (the recomputed root for PCIT/PSIT;
the axes digest over carried other-axes roots plus the recomputed
queried-axis root for PCPSIT, family-checked against axis-relabel
forgery) and requires the parent-committed value_hash to match. The one
echo is the RankOfKey rank, needed to drive the count-offset
verification walk; the count commitments attest it and the yielded
entry must be the queried key.

Branched axis reads fall out of the ordinary walk: branch keys are Key
items at the branching layer (one multi-key merk proof, absence proven
natively), each present branch descends the shared suffix to its own
axis-descent terminal, and the verifier rejects a proof that shows a
branch key present while omitting its axis layer — hiding entries
behind fake absence fails closed.

Surface: prove_query serves axis shapes (V1 envelope only, GROVE_V4's
new proof.axis_descent_in_v1_envelope slot on both sides — V0 refusal
follows the ACOR template); the new verify_path_query is the unified
verify entry returning a typed VerifiedPathQuery for every provable
shape (key selection, all six aggregate forms, axis entries/rank/
aggregate, branched with authenticated absence); the verify_query
family stays key-selection-only. Sum-budget shapes still have no proof
form. The rank computation and attestation-binding cores are factored
from the standalone envelope machinery and shared, not duplicated.

Tests: round trips for every traversal (top-k, paginated, bounded,
rank both directions, range aggregate) incl. PCPSIT multi-axis digest
reconstruction and branched absence; equality cross-checks against
both the trusted reads and the standalone envelopes with matching
root hashes; forgery rejections (forged primary root, relabeled axis
tag, tampered secondary bytes, smuggled other-axes list, lying rank
echo, stripped present branch); V3-refuses/V4-serves gates on both
sides and V0-envelope rejection. Full suite, clippy, verify-only
build green.

…security audit)

Three findings from the adversarial audit of the axis-descent
integration, all fixed with regression tests:

1. Branched absence forgery (Medium). The axis-read check lived inside
   the lower-layer lookup, so a prover could STRIP an axis-descent
   layer whose indexed tree exists but is empty — is_non_empty_tree()
   is false for it, so no guard fired — and the verifier endorsed a
   false 'proven absent' slot under the genuine root hash. The check is
   now hoisted above the lookup: at an axis-read position the layer
   MUST exist (a missing one is a hard InvalidProof), and an existing
   empty indexed tree now reports Some(empty entries), matching the
   honest prover and the trusted read. The branched absence guard in
   verify_path_query also widens to reject any present trio under the
   branch subtree, and the trusted branched read resolves the full
   suffix chain so read and proof agree on None for every
   absence level.

2. Bounded traversal vs empty secondary (Medium). Merk::prove refuses
   empty trees, so a Bounded axis proof over a freshly created indexed
   tree hard-errored while every other traversal — and the trusted
   read — handled it. Both sides now use the same empty convention as
   the count-offset and aggregate-on-range shapes: empty proof bytes
   resolve to a NULL_HASH secondary root, which the parent binding only
   accepts when the element genuinely commits an empty secondary.

3. Duplicate branch keys (Low). classify() now rejects a branched axis
   read naming the same branch key twice — a valid proof could
   otherwise yield contradictory (Some, None) rows for one key.

Also documents why the Bounded secondary executes with the lenient
proof version (only keys are consumed, and they are bound into the
recomputed root); the audit confirmed this is not exploitable today.

[P1] Reject wrong-type axis terminals

Resolve axis_read_at_path before filtering on element.is_indexed_tree(). In a branched query, a present normal tree at the axis terminal skips this check and is omitted from the trio results, so verify_path_query reports the branch as None. I reproduced this with scores = Element::empty_tree(): the proof verified as absent while run_path_query returned InvalidPath("Sum axis not indexed at this path"). Please require that any path governed by an axis read contains a compatible indexed tree before dispatch.

// silently served as a primary descent; matches
// empty primaries too (the payload commits
// NULL_HASH roots naturally).

[P2] Do not emit unverifiable single-axis proofs

For a single-path axis query whose target is missing or non-indexed, this arm never runs, but the generic proof walk still returns Ok with no axis-descent layer. I reproduced a missing target where prove_query succeeded and verify_path_query rejected the result with “must verify exactly one axis layer, got 0.” Please preflight the single-axis target or fail generation when no descent is produced.

QuantumExplorer and others added 2 commits August 14, 2026 17:40
P1 — a branch whose axis terminal is a present NON-indexed element was
reported as proven-absent. The verifier resolved `axis_read_at_path`
only after filtering on `element.is_indexed_tree()`, so an ordinary
tree at the terminal fell through to the normal descent, which yields
no trio for it; the branched arm then saw neither an axis layer nor a
present element and endorsed `None` under a genuine root hash — while
the trusted read rejects the same state as unindexed. The axis read is
now resolved from the query FIRST: any key the query governs as an
axis read must hold an indexed tree, or it is a hard InvalidProof.

P2 — a single-path axis read whose target is missing or non-indexed
produced no axis descent, and the prover returned Ok with an ordinary
layer; only the verifier caught it, as "must verify exactly one axis
layer, got 0". Generation now fails instead. Branched reads are
excluded: an absent branch key legitimately produces no descent, and
the branching-level Merk proof is what authenticates its absence.

Coverage: verify_path_query.rs 48% -> 77%, and the new-code gaps in
verify.rs / indexed_axis / envelope / axis_lowering closed alongside.
Nine differential tests route every non-axis shape (three aggregate
leaves, three aggregate carriers, key selection, count-offset
pagination, the unproved sum-budget shape) through the unified entry
and assert equality with the dedicated verifier it delegates to.
On the axis side: count- and avg-axis round trips (each traversal
fans out per axis on both sides), bounded-over-empty on all three
axes, structural layer forgeries (non-axis bytes, smuggled lower
layers, stray/dropped rank echoes), rank-proof replay for another
key, canonical payload decoding, and axis-read path resolution.

Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
The count axis is the one that reads wrong. "Aggregate over the entries
in [lo, hi]" invites "total of their counts", but a count secondary
aggregates by counting nodes, so the answer is the bucket POPULATION:
over counts [3, 1, 5], the band [2, 10] answers 2, not 8. The sum axis
does total its values, so the two axes genuinely differ and no single
name covers both — the semantics have to be stated, per axis, wherever
a caller meets the number.

Stated at the three points where one does: the traversal variant, the
`new_axis_range_aggregate` constructor, and the verified
`AxisAggregate.value`. The `lo`/`hi` field docs now say they bound the
entry's own axis value, not the aggregate being returned.

Also fixes a book paragraph that filed
`indexed_count_range_aggregate` under "Lookup of count for a key" and
described it as a single primary-node read — that is a different
operation entirely; the range aggregate walks the secondary.

76-117: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Add lowering tests for the Avg axis and for a clamped negative lo.

The tests cover Count and Sum only. Two branches stay untested:

  • The IndexAxis::Avg arm is the only branch that does not clamp before encoding. A regression there changes which secondary entries a proof is about, and this module is the single agreement point between prover and verifier.
  • The Count arm clamps a negative lo to 0. That is the only case where clamping changes the emitted range bound.

2060-2077: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Optional: resolve the axis query once instead of in both the guard and the arm.

The match guard builds lower_path and calls axis_read_at_path, then the arm body repeats both steps and needs a CorruptedCodeExecution branch for the case the compiler cannot rule out. Each matched key therefore clones path twice and resolves the query twice.

If you prefer to keep the current structure, no change is needed; the duplication is bounded by the number of matched indexed-tree keys. An alternative is to resolve the axis query before the match op dispatch for the current key and match on the resulting Option, which removes the duplicate lookup and the unreachable error arm.

1381-1416: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Reuse build_paginated_secondary_proof in build_indexed_axis_paginated_proof.

The new helper duplicates step 4 of build_indexed_axis_paginated_proof at lines 944-968: the same is_count_bearing gate, the same RangeFull inner range, the same prove_count_offset_on_range call, and the same encode_into serialization. The doc comment states this. Two copies of one proof-construction rule can diverge later, and a divergence here changes what the secondary proof attests.

Call the helper from the standalone builder so both wire paths share one implementation.

Remove the leftover doc line above empty_for_axis.

Line 180 still holds /// Whether the result list is empty., which belonged to is_empty. is_empty now has its own doc at line 200. Rustdoc joins line 180 and line 181, so the public empty_for_axis documents itself as an emptiness predicate.

📝 Proposed fix
-    /// Whether the result list is empty.
     /// An empty entry list of the right variant for `axis`.
