Final validation — Phase 2 only (queue backlog)
The protocol-14 history implementation is broadly covered by versioned storage, migration, query, and proof tests. Three issues remain: proof-disabled SDK history requests are still emitted even though the fetch path requires proofs, lifecycle metadata verification disables authenticated absence checks, and the activation migration has no consensus-safe resource bound despite the PR explicitly identifying this as an unresolved release gate. The checked-in non-Rust gRPC bindings also do not expose the new history-v1 messages.

In `packages/rs-sdk/src/platform/query.rs`:
- [SUGGESTION] packages/rs-sdk/src/platform/query.rs:296-326: Reject proof-disabled history fetches before sending an unparseable request
The history query encoder converts the limit and sends `prove: settings.prove` without rejecting proof-disabled settings. Both `DocumentHistory` and `DocumentHistoryProofInfo` use the proved `Fetch` implementations, and no unproved history fetch implementation exists. Therefore `SdkBuilder::with_proofs(false)` sends a request whose response cannot be consumed by these fetch paths and fails later as a missing or invalid proof response. Rejecting this combination during request construction preserves the SDK behavior used by other proof-only queries and gives callers a deterministic local error.
In `packages/dapi-grpc/protos/platform/v0/platform.proto`:
- [SUGGESTION] packages/dapi-grpc/protos/platform/v0/platform.proto:1748-1817: Regenerate checked-in non-Rust protobuf clients for history v1
The proto schema adds `GetDocumentHistoryRequestV1` and `GetDocumentHistoryResponseV1`, but the checked-in Node, web, and Python generated bindings contain no corresponding V1 definitions. The new Rust SDK can use the schema, while consumers using these checked-in language clients cannot construct a V1 request or access the V1 response fields. Since protocol 14 rejects legacy history requests, those clients lose document-history functionality after activation. Regenerate and commit the checked-in language bindings using the repository's gRPC generation workflow.
In `packages/rs-drive/src/drive/document/history/mod.rs`:
- [BLOCKING] packages/rs-drive/src/drive/document/history/mod.rs:234-242: Require absence proofs for history lifecycle metadata
`metadata_query` issues three per-document metadata lookups with `SizedQuery::new(query, None, None)`, and verification explicitly sets `absence_proofs_for_non_existing_searched_keys` to `false`. The lifecycle code uses missing pointer/tree metadata to report states such as `Absent` and zero retained revisions. Without authenticated absence proofs, a response can omit an existing metadata key and still be accepted against the root, so the client can accept an unauthenticated lifecycle state. Give each metadata lookup a per-key limit of `Some(1)` and enable absence-proof verification for this metadata proof.
In `packages/rs-drive-abci/src/execution/platform_events/protocol_upgrade/perform_events_on_first_block_of_protocol_change/v2/mod.rs`:

Every upgrade from a pre-14 protocol synchronously runs `migrate_document_history_storage` in the first activation block and propagates any error. The migration enumerates all contracts and history-keeping document types, reads retained revisions and index references, and applies the work in the activation transaction. There is no consensus-safe bound on revisions, documents, index references, bytes, elapsed time, or memory; the returned statistics are only logged. A permissionless contract owner can accumulate substantial retained history before activation subject to ordinary storage fees, causing every validator to exceed proposal-time or memory limits. A failed round retries the same migration, potentially preventing protocol activation. The PR description explicitly leaves authentic-state timing and validator-resource acceptance incomplete, so the synthetic benchmark does not establish a safe bound. The migration must be bounded or staged, or activation must enforce and demonstrate a pre-activation resource limit that fits the validator budget.

Final validation — Phase 2 only (queue backlog)
The protocol-14 history migration remains an unbounded, synchronous operation inside the activation transaction, and the PR explicitly documents that validator-resource acceptance is still incomplete. The revision selectors also reject values above 65535 despite exposing u64 revisions and using u64 document revision fields, making valid high-revision histories inaccessible through revision-based queries.

- [SUGGESTION] packages/rs-drive/src/drive/document/history/mod.rs:181-185: Do not cap valid 64-bit document revisions at u16::MAX
`DocumentHistorySelector::StartAtRevision` and `Revision` accept u64 values, and the underlying document revision and protobuf fields are also 64-bit. `validate` nevertheless rejects every revision above 65535, so a document with retained revision 65536 or later cannot be addressed through either revision selector. The cast to u16 in `entries_query_v1` explains the implementation limitation but does not establish a public 16-bit protocol limit; replace the offset-based lookup with a range/composite-key query or otherwise support the full advertised revision domain.

(existing thread: https://github.com/dashpay/platform/pull/4652#discussion_r3989209403)
The protocol-14 activation hook invokes `migrate_document_history_storage` synchronously for the entire pre-14 persisted state and propagates migration errors, so the work runs in the activation transaction and is retried if the round fails. The migration enumerates all contracts and history-keeping document types, materializes retained revisions and per-type index inventories in memory, and rewrites the records without a consensus-safe bound on documents, revisions, index entries, bytes, execution time, or memory. A permissionless contract owner can grow this state before activation subject only to ordinary storage fees, potentially exceeding validator memory, I/O, or Tenderdash proposal-time budgets and preventing protocol activation. The logged statistics and synthetic benchmark measure observed work but do not constrain future state or establish a validator-safe upper bound. Bound the migration with an enforceable pre-activation resource limit or stage the work across consensus-safe transactions before activation.

Preliminary review — Phase 1 blocker gate
The current head adds only a JavaScript test stub; the previously identified proof-handling issues are resolved or intentionally deferred. The protocol-14 activation migration remains an unbounded, synchronous operation over permissionlessly growable document history and can exceed proposal or validator resource budgets, so the release-blocking concern remains valid.
Validated blockers were found by the Phase-1 review and confirmed by a fresh verifier. Phase 2 is deferred until a fresh same-head revalidation clears the blocker gate.

(existing thread: https://github.com/dashpay/platform/pull/4652#discussion_r3989209403)
The protocol-14 activation path still runs `migrate_document_history_storage` synchronously for every upgrade from a protocol version below 14, inside the activation transaction, and propagates any error. The migration enumerates the existing contracts, history-keeping document types, retained revisions, and index references without a consensus-safe bound on documents, revisions, bytes, elapsed time, or peak memory. Contract owners can grow retained history before activation while paying only ordinary storage fees. Every validator must then repeat the full migration during proposal processing, and a failed round repeats the same work; an over-budget migration can prevent protocol activation. The testnet inventory and synthetic benchmark establish performance for those specific states but do not impose a limit or demonstrate that future worst-case state fits the Tenderdash proposal and validator resource budgets. Bound the work, stage it across blocks, or enforce a pre-activation resource limit with evidence that it fits the validator budget.

Preliminary review — Phase 1 blocker gate
The protocol-14 history implementation includes authenticated queries and rollback-safe migration behavior, and the previously reported proof, metadata, and test issues were addressed. The activation migration remains an unbounded synchronous operation in the first protocol-activation block, and it also contains a panic path for unexpected persisted data; both can halt or prevent activation and require correction before merge.
Validated blockers were found by the Phase-1 review and confirmed by a fresh verifier. Phase 2 is deferred until a fresh same-head revalidation clears the blocker gate.

- [BLOCKING] packages/rs-drive/src/drive/document/migration/mod.rs:345-360: Return a deterministic error instead of panicking on an unexpected index leaf
The activation migration runs on the block-execution path, but the rewrite closure uses `unreachable!` when an inventory entry is not a reference element. Although valid pre-14 state is expected to satisfy the invariant, corrupted or unexpected persisted state would panic the node rather than return the repository's deterministic corruption error through the migration result. A panic during consensus processing can halt the chain or make activation behavior depend on node-local state handling. Replace this arm with an error such as `return Err(corrupt("unexpected leaf in a historical document index"))`, restructuring the iterator if necessary so the error propagates through `migrate_document_history_storage`.

(existing thread: https://github.com/dashpay/platform/pull/4652#discussion_r3989209403)
The first block below protocol 14 synchronously runs `migrate_document_history_storage` inside the activation transaction. That migration enumerates all retained histories and index references and applies the rewrites without a consensus-enforced bound on work, bytes, elapsed time, or peak memory; the returned statistics are logged but do not constrain execution. Retained history can grow before activation through ordinary permissionless document activity, so the current synthetic/testnet measurements do not establish that the migration fits the Tenderdash proposal budget or validator memory. A failed round repeats the same migration, potentially preventing protocol activation. Bound the migration, stage it across blocks, or enforce a pre-activation resource limit with release-profile evidence on authentic state.

(existing thread: https://github.com/dashpay/platform/pull/4652#discussion_r3995276107)
The public selectors and protobuf fields use `u64`, but validation rejects revisions above `u16::MAX`, and the query implementation then uses a `u16` count-bound offset. This makes part of the advertised selector domain unusable: retained revision 65536 or later cannot be selected by revision-based queries. Time selectors and cursors provide a workaround, but they do not reconcile the public 64-bit type with the explicit ceiling. Either support the full `u64` domain through a suitable range/index query or expose the implementation's narrower limit in the public API and protocol contract.

Preliminary review — Phase 1 blocker gate
The protocol-14 activation migration still executes synchronously over the entire retained-history inventory in the shared activation transaction, without a consensus-safe bound on work, memory, or elapsed time. This can make activation exceed proposal or validator resource budgets as pre-activation history grows, and a failed activation round retries the same migration.
Validated blockers were found by the Phase-1 review and confirmed by a fresh verifier. Phase 2 is deferred until a fresh same-head revalidation clears the blocker gate.

(existing thread: https://github.com/dashpay/platform/pull/4652#discussion_r3989209403)
The protocol-14 activation path synchronously calls `migrate_document_history_storage` for the complete retained-history inventory and propagates any error, while `DocumentHistoryMigrationStats` is only logged. The migration can enumerate contracts and document types, build per-type index inventories, load retained document histories, and rewrite indexes in the shared activation transaction without a consensus-safe limit on revisions, documents, index references, bytes, elapsed time, or memory. Permissionless contract owners can grow retained history before activation subject to ordinary storage fees, forcing every validator to perform the same potentially oversized work during proposal processing. If the block misses the proposal or resource budget, the migration is retried on the next round. The synthetic benchmark and current testnet inventory measure present workload but do not enforce or establish a bound. Stage the migration across blocks, or enforce a deterministic pre-activation limit proven to fit validator budgets.

Re-review — Final validation — Phase 2 only (queue backlog)
Two blocking issues remain: activation performs an unbounded migration, and new history-storage behavior is implemented inside frozen method generations. Expected revision-query rejections also become retryable internal server errors. The two platform-version history regression tests passed; the explicitly documented wire replacement and deferred client regeneration are not additional blockers.

- [BLOCKING] packages/rs-drive/src/drive/contract/insert/insert_contract/v0/mod.rs:289-299: Keep protocol-14 history behavior out of shipped v0 implementations
The new history-tree insertion is implemented directly in `insert_contract_operations_v0`, which `insert_contract_operations_v1` calls. This PR similarly adds history-tree creation to `update_contract/v0` and threads version-dependent reference behavior through `update_document_for_contract_operations/v0`. The structure-version gate preserves the old branch selection for protocols 12/13, so this is not evidence of an existing replay mismatch. It nevertheless violates the explicit frozen-generation rule in `book/src/contributing/coding-conventions.md`, which specifically prohibits adding version checks or parameters inside shipped generations, even when the new branch is inactive for historical versions. Move this PR's history-specific changes into new implementation generations selected only by protocol 14, preserving the shipped implementations and signatures.

- [SUGGESTION] packages/rs-drive-abci/src/query/document_history/v0/mod.rs:83-88: Preserve expected history-query rejections as query errors
Revision filters on migrated histories with gaps deliberately return `drive::error::Error::Query(QuerySyntaxError::Unsupported(...))`. The `?` here, and in the unproved branch, converts that expected rejection into the outer ABCI `Error::Drive`. `query/service.rs::error_into_status` then returns gRPC `Internal`, which the DAPI client treats as retryable, instead of the `InvalidArgument` used for `QueryError::Query`. Consequently, a valid migrated history can produce a misleading server failure and futile retries. Match the Drive query-error variant in both branches and return it through `QueryValidationResult`, while propagating storage and corruption errors normally. The neighboring document-query handler already follows this distinction; add coverage for proved and unproved revision requests on gapped histories.

(existing thread: https://github.com/dashpay/platform/pull/4652#discussion_r3989209403)
This call completes the entire migration synchronously in the activation transaction. Contract enumeration is paginated, but `history_migration_entries` uses unlimited subtree queries, each document's retained revisions are materialized, and `index_entries` holds the complete per-type index inventory. Neither these allocations nor total migration work have an enforced resource budget. Your committed-testnet measurement establishes that the measured inventory is manageable; it does not constrain subsequent valid history growth before activation. A larger inventory can exhaust validator memory or exceed activation-block processing capacity, and rollback leaves that inventory unchanged for the next attempt. Bound the work through deterministic staging with compatible layout routing, or enforce a pre-activation inventory budget demonstrated to fit supported validator resources. A local wall-clock cutoff alone would not be consensus-safe.

- Synchronize generated protobuf clients in the separate follow-up — The checked-in web binding still encodes offset at field 5 and prove at field 7, while the current schema uses those fields for prove and the composite cursor. Regeneration remains a concrete interoperability follow-up. It is excluded from this PR's requested changes because the author explicitly separated generator drift, and the current Evo SDK history facade calls the updated WASM implementation.
- Follow-up: Regenerate and review the checked-in non-Rust clients in the agreed separate PR, including history request/response compatibility checks.

why we split proof? it must be one proof object, isn't?
There was a problem hiding this comment.
They are two proofs because they answer two GroveDB queries that GroveDB cannot merge into one. entries_proof is the offset-paginated proof over the document's history tree (a ProvableCountTree; the revision selectors are served by a count-bound offset, which needs the V1 count-offset envelope). metadata_proof is an exact-key query over three sibling trees, the current pointer, the lifecycle record and the history tree's count, verified with absence proofs so a missing key is proven missing. GroveDB refuses per-instance limits under absence-proof verification and cannot carry offset pagination inside a merged multi-branch query, so one proof would have to give up either the authenticated absence or the pagination. Both proofs are verified against the same root hash under the one signature in the metadata, and the verifier rejects a pair whose roots differ. Comment added in fca0a76.

we have path query merge and things like this. we have one proof always, look at the code and we deal with situations when we have multiple queries/paths
There was a problem hiding this comment.
I checked the code path you mean. PathQuery::merge is what folds several queries into one proof, and it refuses any input that carries an offset: grovedb query/merge/v1.rs returns "can not merge pathqueries with offsets". The by-revision selectors (revision, start_at_revision) are served through the count-bound offset of the history tree, which is the only way to reach a revision without a revision index, so their entries query cannot be merged with the three metadata lookups. That is why the response carries two GroveDB proofs today. To give the API one proof object anyway, I will pack both GroveDB proofs into the single Proof message (one grovedb_proof payload with a small versioned two-part envelope, one signature, one metadata block), so the wire, the verifier and every SDK see one proof; only the drive verifier splits it. The alternative is dropping the by-revision selectors so everything merges natively. Going with the envelope unless you prefer the alternative.
There was a problem hiding this comment.
Done in 34cfacf: the response carries one Proof. Its grovedb_proof is a small versioned envelope (version byte, metadata proof behind a big-endian length, presence byte and, when present, the entries proof behind its length; decoded with full consumption) around the two GroveDB proofs that PathQuery::merge cannot combine because the by-revision selectors need an offset. Callers see one proof, one signature and one metadata block; only the drive verifier splits the payload, and the wasm proof-info result exposes the single proof.

why we need this? we didn't introduce new versions
There was a problem hiding this comment.
It was there because the response did not follow the usual oneof result { data | proof } shape: a proved response carried entries and lifecycle next to a plain proof field, which the derive cannot read. Fixed in f03bdd3: the response is now oneof result { History history = 1; Proof proof = 2; } ResponseMetadata metadata = 3;, the hand-written accessors are gone and the derive covers it. The verifier no longer compares claimed fields against the proof; it returns what the proof authenticates.

Re-review — Final validation — Phase 2 only (queue backlog)
Verification at ef9a812 confirms two blockers: the single-block migration has no enforced resource bound, and the cursor-proof verifier introduces new behavior inside a frozen generation. The new WASM history response also loses the standard serialization methods; the legacy wire/reader replacement is explicitly declared, and generated-client synchronization is deferred. All eight prior findings were reconciled against source; no files were changed and tests were not rerun.

- [BLOCKING] packages/rs-drive/src/verify/document/verify_start_at_document_in_proof/v0/mod.rs:44-45: Put the new cursor-proof path selection in a verifier generation
The existing v0 verifier now passes `platform_version` into the changed cursor-path helper, which selects the legacy document subtree or the protocol-14 primary pointer through `keep_history_storage`. Its dispatcher still supports only version 0, and `DRIVE_VERIFY_METHOD_VERSIONS_V3` inherits `verify_start_at_document_in_proof: 0`. Although the layout gate preserves the old-version path, `book/src/contributing/coding-conventions.md` explicitly forbids introducing new version-dependent behavior by threading a parameter through a shipped generation. Preserve v0's legacy cursor lowering, introduce a v1 verifier for the new layout, and select it only in protocol 14's verification table. Exercise both layouts through the dispatcher.

- [SUGGESTION] packages/wasm-sdk/src/queries/document.rs:1524-1538: Preserve serialization methods on the new history proof response wrapper
`getDocumentHistoryWithProofInfo` previously returned `ProofMetadataResponseWasm`, which exports `toJSON`, `fromJSON`, `toObject`, and `fromObject`. It now returns `DocumentHistoryProofMetadataResponseWasm`, whose exported implementation contains only getters. Consequently, callers lose the standard response serialization API, and ordinary `JSON.stringify` does not serialize the Rust-held data, metadata, and proof through those getters. The new history data shape does not require dropping this functionality. Reuse the common proof-response wrapper or implement equivalent serialization methods with explicit handling for nested documents and BigInt fields.

- [BLOCKING] packages/rs-drive-abci/src/execution/platform_events/protocol_upgrade/perform_events_on_first_block_of_protocol_change/v2/mod.rs:28-32: Bound or stage the attacker-inflatable activation migration
(existing thread: https://github.com/dashpay/platform/pull/4652#discussion_r3989209403)
This hook requires the entire history migration to finish in one activation-block transaction. Contract pagination only bounds individual enumeration pages: `history_migration_entries` performs unlimited queries, retained revisions are materialized together, and `history_migration_index_entries` accumulates the complete per-type reference inventory. The resulting statistics are logged, not enforced as limits. Your authentic testnet measurement establishes that the measured checkpoint is manageable, but neither running once nor having a small current inventory constrains valid state growth before activation. If the inventory exceeds validator capacity, rollback discards progress and the next attempt repeats the same work. Stage migration with deterministic bounded work and memory, or enforce a pre-activation inventory bound and demonstrate that its maximum fits supported validator resources. A timeout that merely aborts the activation attempt does not resolve this liveness problem.
Out-of-scope follow-up suggestions (1)
These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.
- Synchronize generated history clients before publishing them — The checked-in non-Rust bindings still describe the timestamp/offset request and old response entries, while platform.proto now defines the replacement V0 shape. The author explicitly assigned regeneration to a separate PR because the generator also rewrites unrelated stale output; the Evo SDK history facade uses WASM rather than these bindings.
- Follow-up: Complete the separate generated-client update against the final schema and validate request/response serialization before publishing the affected client packages.

Re-review — Final validation — Phase 2 only (queue backlog)
The protocol-14 history storage, proof, version-dispatch, and SDK changes address the prior correctness and compatibility findings. One blocking availability issue remains: activation still performs an unbounded migration of attacker-expandable historical state synchronously in the first protocol-14 block, with no enforced resource bound or staged progress.

(existing thread: https://github.com/dashpay/platform/pull/4652#discussion_r3989209403)
The protocol-14 activation path still runs `migrate_document_history_storage` synchronously whenever `previous_protocol_version < 14`, and it must complete before the activation block can proceed. The migration scans all eligible contracts, document types, documents, retained revisions, and index references, while building inventories and applying the rewrite in the shared transaction; `stats` is only logged and does not enforce a limit on work, bytes, memory, or execution time. Permissionless pre-activation state growth can therefore make the migration exceed validator proposal or memory budgets. If activation fails, the transaction rolls back and the same unbounded work is retried, potentially preventing protocol activation. Bound the migration with a deterministic consensus-safe budget, stage it across protocol-14 blocks with authenticated progress, or enforce and validate a pre-activation inventory limit against supported validator hardware.

Re-review — Final validation — Phase 1 + Phase 2
At cb336dd, the new regressions exercise dynamic and static references against the current document revision while older revisions remain retained. The incremental changes also add separate fee-component assertions and distinguish the legacy exclusive-time API from the V1 query API; no additional defect was confirmed by static verification. Current-head CI now passes native Rust, wasm32, JavaScript builds and Swift validation, superseding the earlier failed jobs; Evo SDK, dashmate and browser test suites remain pending.

🔴 Blocking: Bound or stage the attacker-inflatable activation migration
packages/rs-drive-abci/src/execution/platform_events/protocol_upgrade/perform_events_on_first_block_of_protocol_change/v3/mod.rs:36-39
This hook requires the complete history migration to finish in the activation transaction, after the preceding activation work. Contract-ID pagination does not bound its working set: document/migration/mod.rs accumulates every index reference for a document type in index_entries, materializes the complete primary-key range, and loads and clones each document's retained revisions into operation batches. history_migration_entries uses insert_all with SizedQuery::new(query, None, None), and the raw-query wrapper forwards that query without adding a cap. maximum_type_index_buffer_bound is calculated after allocating the inventory and is never enforced.
The checkpoint measurement and the decision to retain a one-shot migration do not establish a maximum for this allocation. Permissionless, fee-paid writes can enlarge a single type before activation, so state admitted incrementally can exhaust validator memory when materialized together. An OOM or restart loses the transaction's migration progress and repeats the same allocation at activation; rollback protects integrity, not liveness. This concern does not depend on treating the propose timeout as a hard execution deadline. Use consensus-defined persisted progress with bounded batches, or enforce and validate a pre-activation inventory bound covering the complete activation workload. Remeasuring another snapshot alone does not enforce that bound.

Re-review — Final validation — Phase 1 + Phase 2
The current head preserves the protocol-15 history layout, wire-version, proof, and version-table changes verified by the prior review rounds. One in-scope blocking issue remains: activation still performs an unbounded history inventory and rewrite synchronously inside one transaction; Rust, wasm32, Swift, and Kotlin checks passed, while NPM release validation failed during an external wasm-pack download with HTTP 500 and JavaScript/container checks remain pending.

packages/rs-drive-abci/src/execution/platform_events/protocol_upgrade/perform_events_on_first_block_of_protocol_change/v3/mod.rs:36-40
The protocol-15 activation hook still calls migrate_document_history_storage synchronously after the v2 activation work and before the shared activation transaction can commit. The migration paginates contract IDs, but its inner work remains unbounded: history_migration_entries uses unsized queries that materialize complete primary and retained-history inventories, while index_entries retains an entire document type's index-reference inventory in an owned BTreeMap before rewriting it. The calculated maximum_type_index_buffer_bound is only recorded after the allocation and is not enforced, and all copy, delete, pointer, and index-rewrite batches remain in the same transaction. Valid pre-activation state can therefore grow beyond validator memory or proposal-processing capacity, after which rollback or retry repeats the same work from the unchanged committed state. The checkpoint timing is evidence for one observed inventory, not a consensus-safe bound on the state admissible at activation. Stage the migration with consensus-defined progress, or enforce and validate a pre-activation workload bound against the complete current activation block on validator-class hardware.

…roposal-contract-1db678 v5.1-dev gained a protocol version 15 note numbered 35 (composite document history, #4652): the note of a contest among documents becomes 36. Two pinned roots depend on the system contracts and on what v5.1-dev changed since: the ten of nullifier_batch_guard and the state after the protocol version 15 activation. Both are recomputed for the two together. Co-Authored-By: Claude Fable 5.2 <noreply@anthropic.com>
Issue being fixed or feature implemented
Protocol 15 gives every history-keeping document a separate provable count tree. Composite timestamp/revision keys preserve multiple writes in one block, and current-document/index reads resolve through a primary pointer. The activation migration preserves retained legacy revisions, sums and beneficiary flags; previously overwritten legacy revisions cannot be recovered.
Protocol 14 ships with Platform v5.0. This branch targets
v5.1-dev, where protocol 15 is the unreleased activation version, and activates the new storage there next to the other protocol 15 changes. Protocol 14 keeps its released storage layout and every shipped method generation; the history-aware behaviour lives only in new generations selected by protocol 15.What was done?
v5.1-devtables (DRIVE_VERSION_V10with GroveDBGROVE_V5, document method table v5, contract method table v5, verify method table v4, Drive ABCI method table v11) and adds the history selections to them: the history writers, readers and verifier,remove_reference_for_index_level_for_contract_operationsv2 pricing the history and summable reference shapes, first-block hook v3, and query table v3 whose history bounds accept only version 1. Released protocol ≤14 tables are byte-identical tov5.1-devapart from the newdocument_history_storage_layoutfield, which every released document method table sets to the released layout (0).perform_events_on_first_block_of_protocol_changev3 runs the shipped v2 work first and then the history migration when crossing into 15, inside the block's transaction. Contract insert/update v3 wrap the shipped v2 operation collectors and add the history trees for keep-history types. The storage layout is selected by its own version field,document_history_storage_layout(0 = released layout, 1 = history layout, anything else is an error), not by another method's generation. The shipped leaf generations that protocol 14 already uses for other features (update_document_for_contract_operationsv1,remove_reference_for_index_level_for_contract_operationsv1) are untouched and forked into v2 for the history layout.n − 1for revisionn, limit 1–10, both on the page branch only) together with exact-key reads of the current-document pointer and the lifecycle record, with the history tree's count echoed alongside. No other node of the query carries a limit or offset, so a key missing from the proof is proven absent. This needs GroveDBGROVE_V5(feat(query)!: page count trees by a branch-local offset in merged proofs (GROVE_V5) grovedb#1025), which proves a branch-local count offset in a merged query and skips whole subtrees by their committed counts. The response uses the usualoneof result { history | proof }shape; the SDK verifies it like other GroveDB-proof queries, with the protocol version the response was signed at, and requires GroveDB v1 proof envelopes. Revision filters (1–65536) reject retained histories with gaps, and a page must agree with the proven revision count. The released version 0 request and response are unchanged and still served from the released layout up to protocol 14; protocol 15 selects query table v3, whose history bounds accept only version 1, so the standard version check refuses version 1 before activation and version 0 after it.startAtMsbound means the same on both layouts: the pre-15 reader takes an exclusive bound, so the query maps the filter onto it in one place shared by fetch, prove and verify.0ea327d7(feat(query)!: page count trees by a branch-local offset in merged proofs (GROVE_V5) grovedb#1025 ondevelop), which adds branch-local count offsets, merge v2 and trusted parent-tree echoes toGROVE_V5;v5.1-devpinned the commit just before it.Cargo.tomlandCargo.lockotherwise equalv5.1-dev.

In September, an earlier revision of the activation migration was run against an authentic testnet committed-state checkpoint (height 570745, root hash verified against the block app hash): 3,834 contracts, 51 keep-history document types, 595 documents, 644 retained revisions, 1,142 index references. Migration took about 1.7 s CPU and about 5 s wall on a laptop with about 250 MB peak RSS, against the 30 s Tenderdash propose timeout, and produced the same root on every run. Before the 5.1 release the current migration will be measured again on testnet and mainnet state, together with the rest of the protocol 15 activation block, on validator-class hardware (2 vCPU) and with a snapshot that contains ranked/time-range keep-history indexes; the benchmark harness is kept out of this PR.

GROVE_V5at protocol 15: protocol 14 and non-history protocol 15 state roots, proof hashes and fees captured before the GroveDB bump are unchanged; merged path queries and trusted reads with nested subqueries and branch limits give the same rows, costs and proofs as before the bump; the protocol 15 activation block (DPNS v3 rebuild, then the history migration) has the same state root under V4 and V5.History: one-proof round trips for every filter and lifecycle state, both pointer element types, fetch/proof parity, a structural check that no limit or offset sits above the page, decoder rejections (page length vs proven count, duplicate or wrong-type rows), forged signed versions, and a protocol 14 version 0 response verified by a protocol 15 client.

The history query moves to wire version 1. The released version 0 shape is kept unchanged and served up to protocol 14, so 5.0 clients and 5.1 nodes interoperate during the upgrade; after protocol 15 activates, version 0 is refused with the unsupported-version error and clients must use version 1. The 5.1 SDKs send version 1 only, so their history reads need a protocol 15 network. After protocol 15 activation, single-document point-in-time reads (
SingleDocumentDriveQueryin Drive's Rust API and wasm-drive-verify) return the newest retained revision at or before the requested block time, clamped toi64::MAX; the highest revision wins at equal timestamps. Times before the first retained revision return absence. Migrated histories expose only the revisions the previous layout retained, and new histories keep same-time revisions separately. A timed keep-history query inMaybeContestedstatus is refused, because the contested store keeps no history; an explicitlyContestedquery ignores the time. Documents queries (DriveDocumentQuery) with a block time on keep-history types remain refused after activation. Keep-history documents still cannot be deleted.Protocol 15's summable-index fee estimate correction is inherited from v5.1-dev (#5858). This PR adapts index references and their size estimates to the current-revision pointer (42-byte references for keep-history types) and accounts for the retained-history trees.
Rust API (
drive): the releasedDrive::fetch_document_history,prove_document_historyandverify_document_history, which take a contract id, document type, document id, an exclusive start time, a limit and an offset, are renamedfetch_document_history_after_time,prove_document_history_after_timeandverify_document_history_after_timewith the same arguments and results. The original names now take a&DocumentHistoryDriveQueryand accept only method version 1 (protocol 15).Checklist:
