Introduces the indexOnly storage mode at the schema/validation layer: documents of an indexOnly type are never written to primary storage — the index entries are the rows, each terminating in an Item keyed by the index's terminal property ($ownerId by default, or a refersTo-typed identifier) instead of a Reference keyed by the document id. Parser generation 3 / meta-schema v3 (both PV14-introduced and unreleased, extended in place) admit two new keywords: - indexOnly (doc-type level): parsed pre-core like the aggregate keywords and applied by apply_index_only, which enforces the structural matrix the on-disk layout depends on regardless of full_validation: every property required and indexed, $ownerId recoverable from at least one index (delete authorization), immutable / non-transferable / no history / no transient properties, no doctype-level aggregates (no primary tree), and per-index rules (non-unique, non-contested, count axes only, no timeRange, at least one prefix property, terminal typing). - terminal (index level): the member-key property; normalized to $ownerId when omitted, must be $ownerId or an identifier property with a refersTo declaration, and must not repeat a listed index property. Generations <= 2 reject terminal byte-identically to any unknown index key and ignore indexOnly non-validating exactly as they ignore every doctype keyword they predate. indexOnly is immutable across contract updates (validate_config); the terminal rides the existing full-equality index immutability. Storage, transitions, and query support land in follow-up PRs per the indexOnly implementation plan. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The Drive storage layer for indexOnly document types (stacked on the DPP schema PR): no primary-storage row and no [0] primary-key tree — each index writes [...values, 0, <terminal value>] -> Item(b"", flags), the member key sitting exactly where docId sits in the non-unique reference layout, so count/ranked tree derivation and group pruning are untouched. Every branch is gated on index_only()/IndexLevelTypeInfo.terminal, which only a PV14+ contract can set (the grammar rejects the keywords below meta-schema v3) — the same in-place gating the count/sum flags already use in these methods, keeping historical replay byte-identical. One dormant version slot is added for the genuinely new method (delete.delete_index_only_document_for_contract_operations, 0 in every table). - dpp: IndexLevelTypeInfo.terminal (levels merge across indexes; each terminating level belongs to exactly one index); apply_index_only now rebuilds index_structure after terminal normalization — the core parser builds it pre-normalization, so a defaulted $ownerId terminal was missing from the levels. - contract registration skips the [0] tree for indexOnly doctypes; top-level property-name trees (incl. ranked indexed variants) unchanged; registration estimation keeps the primary weight (safe overestimate). - insert: orchestrator skips the is_update probe and primary storage; the terminal writer's indexOnly branch inserts the member Item if-not-exists and errors on an existing entry (backstop behind the coming ABCI state-validation probes). Takes &PlatformVersion now (it reads the member key off the document) — pure signature widening. - delete: new delete_index_only_document_for_contract(_operations) taking the document reconstructed from the transition's values + owner; remove-side terminal branch keys by terminal value and prunes drained groups so ranked secondaries drop them. Delete-by-id on an indexOnly type errors with guidance. - estimation: dry-run pads the item value to 16 bytes so estimated fees upper-bound applied fees across the indexed-tree layers' documented under-count; every traversed level emits its layer info. Pinned e2e suite (yappr-likes fixture, real grovedb): registration shape, per-index terminal items incl. a refersTo-typed postId terminal, duplicate refusal, Item/Reference count parity with ranked ordering global and per-hashtag, delete symmetry with group pruning + integrity sweep, and estimated >= actual fees.

The transition surface and consensus validation for indexOnly document types (stacked on the storage-layout PR). Creates reuse DocumentCreateTransitionV0 unchanged (the entropy-derived id is a transient handle — nothing ever stores it); deletes gain a V1 variant carrying the document's full property-value tuple, since there is no primary-storage row to fetch values from. $createdAt rides in the data under its system key when set. - DocumentDeleteTransitionV1 with create-style manual serde; from_document auto-selects V1 for indexOnly types so every SDK path produces the variant the structure gates require. - STATE_TRANSITION_SERIALIZATION_VERSIONS_V3: PV14-only fork (V2 was shared back to PV10) raising the delete bound to max 1, default 0. validate_base_structure_v0 rejects a V1 delete when the active bound is below 1 — old software cannot decode the variant, so no historical block contains one; the gate keeps new software agreeing with old at check_tx while a pre-PV14 version is active. - Action layer: DocumentDeleteTransitionActionV1 + transformer; new DocumentOperationType::DeleteIndexOnlyDocument whose converter reconstructs the document via Drive::index_only_document_from_values and calls the delete-by-values path. - Drive::has_index_only_document_entry / index_only_entry_path_and_key: probes encoded through Document::get_raw_for_document_type — the same function the walkers key trees with, so probes cannot drift from the write path. - ABCI create state (v1): skips the fetch-by-id probe and the unique-index engine for indexOnly types; probes EVERY index's entry — any existing entry is DuplicateUniqueIndexError (the any-entry-exists rule: shorter/owner-less indexes double as uniqueness constraints). - ABCI delete state (v0): one probe of an $ownerId-bearing entry computed with owner = signer proves existence AND ownership (all of a document's entries exist or none do; the owner is embedded in the probed path/key). Structure gate pairs variant with storage mode. - All in-place branches gated on index_only()/the V1 variant, which cannot occur historically; one PV14-only table fork as above. Tests: full ABCI pipeline suite over the yappr-likes fixture (create, duplicate rejection, owner-scoped deletes, unlike/re-like, forced-V0 refusal, grovedb integrity) — the first draft incidentally proved refersTo composes unchanged (a like on a nonexistent post is rejected with ReferencedEntityNotFoundError); dpp wire-gate pin (V1 rejected at PV13, admitted at PV14). dpp 4075 / drive 3451 / drive-abci 2755 green.

Preliminary review — Codex only
The PV14 gating and V1 action plumbing are coherent, but four in-scope blockers remain in delete authorization, schema validation, intra-batch collision handling, and fee accounting. The current delete model can remove entries from unrelated tuples, while malformed or colliding transitions can escape consensus validation and every new index probe is unbilled.
Source: reviewer evidence — codex-general, codex-security-auditor, and codex-rust-quality (exact backend model ID not supplied); final verifier — Anthropic Claude Agent SDK (exact backend model ID not exposed); orchestration-only — openclaw-agent/cliproxy/gpt-5.6-sol (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-abci/src/execution/validation/state_transition/state_transitions/batch/action_validation/document/document_delete_transition_action/state_v0/mod.rs:71-102: A single partial index probe does not authenticate the complete value tuple
The selected owner-bearing entry commits only to that index's projection, not to all values carried by the delete. The contract parser requires every property to occur somewhere and at least one index to contain `$ownerId`, but it does not require one owner-bearing index to cover the complete tuple. For example, a valid type can have `[slot] -> $ownerId` and `[slot] -> target`; an attacker with `(slot=S, target=A)` can combine their owner entry with a victim's `target=V`. The probe for `(S, attacker)` succeeds, after which execution recomputes every index from `(S,V)` and removes the victim's ownerless entry. Atomic creation does not establish a relationship between independently addressed entries in a newly submitted hybrid tuple. Deletion must verify an owner-authenticated entry that commits to every value used by every index, or each entry must carry a common document identifier or tuple commitment.
In `packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/batch/action_validation/document/document_delete_transition_action/advanced_structure_v0/mod.rs`:
- [BLOCKING] packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/batch/action_validation/document/document_delete_transition_action/advanced_structure_v0/mod.rs:40-64: Delete V1 data is never validated against the document schema
This structure check only pairs the delete variant with the storage mode; it never validates the untrusted V1 `data` map against the contract. A caller can omit required indexed properties, provide incorrectly typed values, add unsupported properties, or provide an invalid `$createdAt`. Missing properties and malformed timestamps then become internal Drive or `CorruptedCodeExecution` errors while deriving index keys, and malformed values outside the selected owner-bearing index can pass state validation before operation conversion fails. Since these values directly select storage entries, advanced structure validation must validate the user-property map with the contract's document-property validator and separately validate and remove the transported `$createdAt` system field before state probing.
In `packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/batch/action_validation/document/document_create_transition_action/state_v1/mod.rs`:
- [BLOCKING] packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/batch/action_validation/document/document_create_transition_action/state_v1/mod.rs:94-123: Entry collision checks ignore sibling transitions in the same batch
Every action in a `BatchTransition` is state-validated before any of that transition's low-level writes are applied, so these probes see only the pre-batch transaction state. The DPP duplicate check fingerprints `(document_type, id)`, while two indexOnly creates can have different valid entropy-derived IDs but identical index values. Both creates therefore see the entries as absent and pass, after which operation conversion emits multiple GroveDB operations for the same qualified keys instead of returning `DuplicateUniqueIndexError`. Two V1 deletes with the same values and different IDs have the symmetric problem. Batch validation must track derived index entry path/key pairs across sibling actions and reject create/create and delete/delete collisions before operation generation.
- [BLOCKING] packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/batch/action_validation/document/document_create_transition_action/state_v1/mod.rs:94-107: Index entry probes discard all calculated query costs
`has_index_only_document_entry` ultimately calls `grove_has_raw`, which appends a `CalculatedCostOperation` to `probe_operations`. This loop drops that vector without converting its costs into a fee result or adding them to `execution_context`, including when it returns early for an existing entry. The V1 delete probe in `document_delete_transition_action/state_v0/mod.rs` repeats the same omission. Consequently indexOnly creates perform one unbilled stateful GroveDB read per index and deletes perform another unbilled read, making fee calculation systematically diverge from the validation work validators execute. Accumulate every probe's cost into `execution_context` on successful and consensus-error paths.
…ping, timestamp requiredness Review fixes for the indexOnly schema layer: - EVERY index must now embed $ownerId (property or terminal), not just one: entries are self-authorizing, so a crafted delete can no longer splice a victim's owner-less row in with the signer's own owner-bearing row. Drops the owner-less global-uniqueness shape (unneeded). - Terminal typing matches the four single-id refersTo targets explicitly; identityPublicKey is rejected — it is a compound reference (key id in a companion property), so a terminal keyed by it would conflate keys. - An index involving $createdAt requires "$createdAt" in `required`: creation only assigns the timestamp for required system times. - Every ancestor object of an indexed dotted property must be required — a required leaf inside an optional object is only conditionally present. - set_index_only removed from the public setter API (parser-only flag; the parser writes the crate-visible field directly). - Index::try_from_value_map now takes IndexGrammarAdmissions instead of three same-typed positional bools, so a transposition cannot silently change which generation-3 keywords are admitted. - Added the missed `terminal: None` in drive_document_count_query's multi-line Index literal (workspace test-build fix). New tests: identityPublicKey terminal rejection, unrequired-$createdAt rejection, owner-less index rejection; updated shapes for the tightened rules. dpp 4077 green; drive test target builds.

Follow-through on the schema-layer review fix that made every index owner-bearing: the delete state validation now probes ALL of the document's index entries (each embeds the signer as owner), so a values tuple spliced from different documents fails validation cleanly with DocumentNotFound instead of failing mid-apply, and ownership is proven by every probe rather than one. Refreshes the probe-module docs that still described the owner-less/global-uniqueness shape. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Review fixes for the indexOnly storage layer: - Every terminal item now stores a 32-byte ROW COMMITMENT — hash_double(owner + all property raw index bytes in sorted-name order + createdAt when set) — binding each independently stored projection to its document's full value tuple. Together with the schema rule that every index embeds $ownerId, this is what lets delete validation (stacked ABCI PR) reject a values tuple spliced from two different creates: the entries exist, but they carry different commitments. Dry-run estimation pads above the real payload so estimated fees keep upper-bounding applied fees. - delete_index_only_document_for_contract moved behind its own dormant method-version slot with the full orchestration in v0, and now takes previous_fee_versions, forwarding it to fee calculation like the stored-document deletion APIs. - The index walkers' storage-flag gate now also passes flags for indexOnly types whose doctype allows deletion (immutable-yet-deletable is exactly their shape; the old mutable-or-contract-deletable gate stored their entries flagless and silently forfeited refunds). PV14-scoped, so historical replay is untouched. - e2e: terminal payload assertions pin the commitment (identical across all of a document's entries); duplicate-entry test asserts the CorruptedContractIndexes variant; new refunds test inserts with SingleEpochOwned flags and asserts a later-epoch delete refunds the inserting owner. dpp 4077 / drive 3452 green; clippy clean. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…oof delete variant selection Follow-through on the storage-layer review's row-commitment change: - Delete validation (ABCI) and the storage-layer delete both now require every probed entry to carry the row commitment the submitted tuple produces (index_only_entry_commitment_matches), not bare existence — a tuple spliced from two documents, even two by the same owner, is refused cleanly with DocumentNotFound / DeletingDocumentThatDoesNotExist and both real rows keep every projection. - New splice e2e over a purpose-built two-single-property-index doctype (the splice-prone shape; likes are immune only incidentally via their compound index): spliced tuple refused, both rows individually deletable afterward, grove consistent. - DocumentDeleteTransition::from_document now raises the table default to 1 for indexOnly types instead of pinning it (max(default, 1)), so a future values-carrying default above 1 keeps winning.

Thread the doctype's indexOnly flag into the shared parse core so parse_indices normalizes an omitted terminal to $ownerId BEFORE the index structure is built.

Preliminary review — Codex only
The current head fixes the four previously verified authorization, schema-validation, batch-collision, and discarded-query-cost findings. Two blocking fee-accounting defects remain: execution performs integrity reads that estimation skips, and repeated row-commitment hashing is not represented in the fee pipeline; the new manual V1 serde path also lacks direct round-trip coverage.

- [BLOCKING] packages/rs-drive/src/drive/document/delete/delete_index_only_document_for_contract_operations/v0/mod.rs:140-159: The storage integrity gate disappears from fee estimation
`apply_drive_operations(..., apply = false, ...)` supplies `Some(estimated_costs_only_with_layer_info)`, so the fee-validation dry run skips this entire integrity loop. Execution supplies `None`, performs one stateful `grove_get_raw_optional` per index, and appends those `CalculatedCostOperation`s to the actual low-level batch. The earlier ABCI probes are included through `execution_operations` in both the estimated and actual fee, so they do not account for this second, execution-only set of reads. This leaves no estimated operation or maintained upper bound corresponding to work charged only during execution, violating the required `estimated >= actual` fee invariant. Run equivalent stateless estimated probes or avoid repeating the already-authenticated reads during application.
In `packages/rs-drive/src/drive/document/index_only.rs`:
- [BLOCKING] packages/rs-drive/src/drive/document/index_only.rs:160-164: Row-commitment hashing is omitted from fee accounting
Each call recomputes `index_only_row_commitment`, which sorts the flattened property names, encodes every property value, builds the complete tuple preimage, and performs a double SHA-256. Delete state validation calls this once per index, and the storage-layer backstop repeats it once per index, but their operation accumulators receive only the subsequent GroveDB query costs. No `ValidationOperation::DoubleSha256` or `LowLevelDriveOperation::FunctionOperation(HashFunction::Sha256_2)` bills the new hashing work. Compute the expected commitment once per probe loop where possible and add a deterministic hash-cost operation for every hash that remains in both validation and application.

- [SUGGESTION] packages/rs-dpp/src/state_transition/state_transitions/document/batch_transition/batched_transition/document_delete_transition/v1/mod.rs:52-81: The V1 manual deserializer has no V1 round-trip coverage
This hand-written deserializer relies on an exhaustively maintained list of flattened base keys; an omitted current or future base key is silently routed into document data. The delete JSON/value fixtures and umbrella tests construct only `DocumentDeleteTransition::V0`, while the ABCI tests exercise platform binary serialization rather than this serde implementation. Add V1 JSON and platform-value round-trip fixtures containing non-default V1 base fields, ordinary document properties, and `$createdAt`, and assert the complete flattened wire shape and recovered value.

…x positions Rebased onto v4.2-dev after #4497 (indexOnly delete as its own transition kind, superseding #4493): the executed-transition prover and verifier now match DocumentTransition::IndexOnlyDelete, whose data() is non-optional — the values-missing error paths are gone — and the by-id verifier arm for the new kind now covers only the degenerate stored-doctype case. Queries synthesize documents from index positions via query/index_only_synthesis.rs (one builder shared by server and verify); executed indexOnly transitions are proven against the single entry their values produce (create = present, delete = absent) through the same path-query builder on both sides.

Third PR of the indexOnly document types stack (on #4492): the transition surface and ABCI validation. Creates reuse
DocumentCreateTransitionV0unchanged; deletes gain a values-carrying V1 variant, since there is no primary-storage row to fetch values from.What was done?
DocumentDeleteTransitionV1(dpp):{ base, data }with the full property-value tuple;$createdAtrides indataunder its system key when set (an indexOnly type may index it, and then it is part of the entry paths being removed). Manual serde mirrors the create transition's flatten-catchall routing.from_documentauto-selects V1 for indexOnly types, so every construction path — SDKs included — produces the right variant with no per-client knowledge of the storage mode;method_feature_versionstill overrides.Wire gating:
STATE_TRANSITION_SERIALIZATION_VERSIONS_V3(PV14-only fork of V2, which was shared back to PV10) raises the delete bound to max 1, default 0.validate_base_structure_v0rejects a V1 delete when the active version's bound is below 1 — old software cannot decode the variant at all, so no historical block contains one; the check keeps new software agreeing with old software at check_tx while a pre-PV14 version is active.Action layer (drive):
DocumentDeleteTransitionActionV1+ transformer; op conversion emits the newDocumentOperationType::DeleteIndexOnlyDocument { document_id, owner_id, data, … }, whose converter reconstructs the document via the sharedDrive::index_only_document_from_valuesand calls the Phase-2 delete-by-values path.ABCI validation (all in-place branches on
index_only()/ the V1 action variant — unreachable for anything historical):Drive::has_index_only_document_entry(path/key derived throughDocument::get_raw_for_document_type— the same encoding the walkers write with, so the probe cannot drift). Any existing entry →DuplicateUniqueIndexErrornaming that index's properties + terminal. This is the plan's any-entry-exists rule: a shorter or owner-less index doubles as a uniqueness constraint.fetch_document_with_idwith ONE probe of an$ownerId-bearing entry computed with owner = signer. All of a document's entries exist or none do (create writes and delete removes them atomically), and the owner is embedded in the probed path/key — so the single read proves existence AND ownership. Missing →DocumentNotFoundError.$id(the id is never stored; the read path will synthesize a deterministic id in the query PR). This dropped the planned zeroed-entropy rule and its structure-validation churn.How Has This Been Tested?
batch/tests/document/index_only.rs, yappr-likes fixture shared with rs-drive): post created, then like create → duplicate like →DuplicateUniqueIndexError; second owner's like OK; a delete with identical values signed by another owner removes only that owner's entries (and errorsDocumentNotFoundErrorwhen they have none); unlike + re-like; grovedb integrity sweep clean. Second test pins the structure gate refusing a forced-V0 delete on an indexOnly type.ReferencedEntityNotFoundError— incidental proof that refersTo validation composes with indexOnly creates unchanged (it reads transition values, not storage). The suite now creates the referenced permanent document first.cargo testgreen on dpp, drive, and drive-abci (lib).Breaking Changes
Consensus: new delete transition variant + validation paths, all PV14-gated (unreleased).
Checklist:
Stack: #4491 (DPP schema) → #4492 (storage) → this → query+proofs → SDK/e2e.
Known follow-ups: probe costs are not yet billed to the execution context (mirrors several existing validation reads); wasm-dpp JS bindings for delete V1 ride the SDK PR.
