Issue being fixed or feature implemented

Fixes #5440 (plan item C3).

Platform keeps its own copy of Dash Core's masternode list. It builds the copy from Core's full list at init chain, then applies Core's protx listdiff diffs block by block. Each masternode's operator identity gets a TRANSFER key (ECDSA_HASH160 of the operator payout address), and that key signs credit withdrawals from the identity. Up to protocol version 14 the payout handling was broken in two ways:

1. A payout change never reached Platform. Platform took the operator payout only from a masternode's full state: the init-chain list, or a masternode that is new in a diff. It ignored the payout in a diff (rust-dashcore did not decode it before ci: cancel runs for already merged PRs #1179, and fix(drive-abci): apply masternode list diffs as v0 and v1 always have #5455 strips it). So:
   • The stored payout never changed after Platform first saw a masternode.
   • A ProRegTx cannot carry an operator payout; only a later ProUpServTx sets one. So nearly every masternode registered after Platform genesis with an operator reward has an operator identity without a TRANSFER key, and nobody can withdraw credits sent to it.
   • An operator who changed the payout in Core kept the old address as the Platform key.
2. A new operator inherited the previous operator's payout key. Core clears the payout on every operator key change (ProUpRegTx with a new key, ProUpRevTx). update_operator_identity v0 still gave the new operator identity a TRANSFER key from an existing key or from the stored payout, both of which belong to the earlier operator.

On mainnet, from the repo fixture at Platform genesis and today's public masternodelist:

• At genesis: 3,728 masternodes, 227 of them with an operator reward and 225 with an operator payout.
• Today: 3,001 masternodes, 1,125 registered after genesis.
• About 70 operator identities are probably missing their key (the genesis rate of ~6% applied to those 1,125).
• 31 masternodes from the genesis era have changed operator key since; one of them has an operator reward.

No user has lost anything yet. An operator identity receives credits only through the owner's rewardShare documents, and the public explorer shows 0 such documents on mainnet and 0 on testnet. The wrong keys guard empty balances today.

Both items change identity keys in GroveDB, so the fix starts at protocol version 15 (unreleased: testnet runs 14, mainnet 13). Protocol versions 1 to 14 replay exactly as before.

What was done?

Everything below is selected only by protocol version 15's table (DRIVE_ABCI_METHOD_VERSIONS_V11, amended in place).

update_masternode_list 2 (update_state_masternode_list_v2, a copy of v1):

• A diff's operator payouts are kept.
• For an operator key change that Core prints without a payout, the payout is read from Core: get_masternode_state (getblockhash(c), then protx info <proTxHash> <blockHash>) at the block's chain-locked height. Only the answer's state is decoded. rust-dashcore's typed ProTxInfo reads operatorReward as an integer, while Core prints a decimal (13.37 and 2.5 on mainnet), and its metaInfo holds node-local numbers. The hash is sent in Core's form (to_string; to_hex is byte-reversed). Core empties the payout on every key change and prints nothing for the clear. It also prints a payout only when it differs between the diff's two heights, so an entry without one cannot tell "cleared" from "set again to the same payout" (rotate and restore inside one c range). Only such entries trigger the call: about one per operator key change, and mainnet has had 31 since Platform's genesis. A Core error fails the block. A payout printed in the diff is used as is.
• A key that Core only re-encoded is dropped before the clear is inferred, as fix(drive-abci)!: keep the operator identity when Core re-encodes the same operator key #5461 does, so a re-encode is never read as a key change. Whether V24 is active now comes from the Core fork record (fetch_core_fork_activation_height) instead of a Core call. The list update runs inside update_core_info v1, after the record step at the same c, and only in blocks that move c, so the record gives the same answer Core would.
• Diffs apply with DMNState::apply_diff, which keeps a revived height the diff does not print.

update_operator_identity 1:

• Given a payout, it reconciles every TRANSFER key of the identity it updates:
  • it reuses the key holding the payout (an enabled one first) or re-enables it;
  • it adds the key if there is none;
  • it disables every other enabled TRANSFER key.
• There are no fallbacks to an earlier operator's key, and a key change without a payout means no payout.
• It is idempotent: a payout Core re-sends cannot add a duplicate key, which with v0 fails IdentityKeyAlreadyExists on every node and halts the chain. Step 5 of the spec's earlier draft, a filter for re-sent payouts, is therefore not needed and was dropped. Keeping it would also stop a re-sent payout from healing an identity's keys.
• A key change never touches the TRANSFER keys of an operator identity that already exists, whatever the payout. The identity a masternode leaves keeps its TRANSFER keys, so its operator can still withdraw what was sent to it, and so does a retired identity the masternode switches back to. The stored payout still follows Core. An existing identity's TRANSFER keys change only with a payout change Core reports while it stays the masternode's operator identity, which reconciles them as above and disables a key left by an earlier operator.
• Why: the owner alone authorizes an operator key change (Core authenticates ProUpRegTx with the owner's key), so neither a switch back without a payout nor the payout reported with one need be the returning operator's own choice. Reconciling with it would let an owner take away, without operator A's consent, A's authority over the credits A accrued, for example by rotating A → B → A (no payout) → B, which disabled every TRANSFER key of A's identity.
• Accepted trade-offs: a retired identity that still holds a PV14-era first-seen payout key of an earlier operator keeps it enabled after a switch back until the returning operator changes its payout. This narrows the fix of spec failure F4 (≤1 masternode on mainnet), and that key already had authority over the identity's balance while the identity was retired. A payout reported with the switch back reaches the returning identity's keys only with the operator's next payout change, even when the operator chose it.
• Each step touches only its own kind of key: the BLS operator key, the platform node id key, the TRANSFER keys. So one key is never disabled or re-enabled twice in one update. Without this, an operator could set a payout equal to its platform node id and fail the block on every node; the code review found that chain halt.
• A key whose public-key hash another key of the identity already has is added like any other. Payouts and node ids are any 20 bytes Core accepts, so an identity can need two keys of different kinds with one hash. Drive used to fail such an add with IdentityKeyAlreadyExists.

Drive add_new_keys_to_masternode_identity 1 (new slot: 0 in every shipped DRIVE_VERSION, 1 in DRIVE_VERSION_V10, which only PV15 selects): a masternode key whose hash the identity already holds a non-unique key-hash reference for, or that an earlier key of the same call has, is added without a second reference. Each key keeps its own id and purpose. User identity updates keep add_new_keys_to_identity and are unaffected.

Drive apply_drive_operations 2 (PV15-only, amended in place): after a batch is lowered, it keeps the first of the identical inserts that create a hash's tree under the non-unique key hashes tree. Each identity operation is lowered against stored state, so several identities adding a key of one new hash in one batch each queue that tree; masternodes whose operators share a payout address do this in the reconciliation. A batch checked for consistency (batching_consistency_verification) refused the repeats. The unchecked default kept the last of the identical inserts, so default nodes write the same state either way.

One-time reconciliation in the first block of protocol version 15 (transition_to_version_15 → reconcile_operator_payouts_with_core):

• It reads Core's full masternode list (protx listdiff 1 c_prev) at the last committed chain-locked core height c_prev, the height Platform's list is at when the upgrade hook runs. The block's own diff c_prev → c is applied afterwards, under the new rules.
• Where a stored payout differs from Core's, it stores Core's. Every masternode's current operator identity goes through update_operator_identity 1 with Core's payout. That reconciles all of its TRANSFER keys and changes nothing where they already match. The stored payout alone does not tell which identities need it: up to PV14 a platform node id matched keys by data alone, so an evonode whose node id once had its payout's bytes can have its payout key disabled while the stored payout and Core's agree.
• There is no GroveDB record. The first block of a protocol version is unique by construction, and a jump from 13 or 14 straight to 16 or later passes through the same ladder step.
• A Core error fails the block. So does a Core list whose masternodes are not Platform's; the error names the first 10 mismatched masternodes on each side. A malformed answer (removals, updates, a masternode listed twice) also fails the block.

Why read Core in the upgrade block here, when core-fork-activations.md avoids it for the fork probe:

• A one-time reconciliation needs Core's full list. Nothing in Platform's state can replace it.
• c_prev is chain locked and an earlier block already read Core at it, so every validator's Core holds that block and reports the same list.
• The cost is accepted once: a node whose Core cannot answer cannot execute that one block, whatever its own c.
• The book's paragraph now says this.

Why c_prev and not the proposal's c: the hook runs before update_core_info applies this block's diff. Reconciling the c_prev list against Core's list at c would compare two different lists. For a masternode whose operator key changes inside c_prev..c, it would also give the old operator's retired identity the new operator's payout key, which the following diff cannot undo.

Budget: infraclaw measured protx listdiff 1 <tip> on a mainnet Core (Dash Core 23.1.3, 3,001 masternodes) at 4.45 s cold and 0.80 s warm, for 3.3 MB of JSON. A one-block diff takes 0.07 s. Against the limits:

• Tenderdash's genesis propose timeout is 50 s (testnet 30 s), so the upgrade block fits with room to spare.
• drive-abci's proposer tx-processing limit (5,000 ms on mainnet and testnet) is measured from the start of prepare_proposal. With a cold Core, the proposer leaves the upgrade block's state transitions unexecuted (ProposerRanOutOfTime), and they go into the next block. Nothing fails.
• Identity work: one key read per masternode (about 3,000 on mainnet), plus key writes for the few hundred mismatches at most. Estimated at 1-3 s; not measured on mainnet hardware. Together with the Core read, the upgrade block likely carries no state transitions on the proposer (above), which is harmless.

Plumbing and tests:

• perform_events_on_first_block_of_protocol_change (dispatcher and all three generations) gains block_platform_state: &mut PlatformState and a CoreRPCLike bound. Only transition_to_version_15 uses them.
• Tests that run the protocol 15 upgrade on a platform without masternodes get a mock Core that lists none (TempPlatform::with_no_core_masternodes, full lists only).
• The strategy tests' Core mock now answers a full-list request at a later height with the strategy's list at that height, instead of the genesis list.
• Book: core-fork-activations.md Consumers (the list update reads the record from generation 2 on) and the upgrade-window paragraph; component-pipeline.md "Syncing with Dash Core" (the upgrade block's Core read).
• PV15 note 28 in v15.rs (notes 22 to 27 come from v5.1-dev: 22 and 23 are fix(drive-abci)!: re-enable the voter key of the address a masternode returns to (PV15) #5768's and feat(drive-abci)!: check the IdentityCreate identity id in basic structure (PV15) #5770's, and 24 to 27 the DashPay v3, private document entry, GroveDB V5 and refund notes), and the doc comment of the v11 table.

dashmate: Core refuses a method to drive's consensus RPC user until its whitelist names it. So protxinfo joins the default drive_consensus whitelist, and a 5.1.0-beta.1 migration adds it to existing configs. A user without a whitelist already may call every method. The migration has a unit test.

Core loads the whitelist only when it starts, so Core must be restarted after the whitelist change, before the first protocol version 15 block that reads protx info; until then Core refuses it (HTTP 403) and that block fails. Restarting Core after a whitelist change belongs to dashmate's update path, which is separate work. drive-abci does not check the whitelist at startup: how dashmate configures Core's RPC users is not drive-abci's concern.

update_masternode_list v0/v1, update_state_masternode_list v0/v1 and update_operator_identity v0 are byte-identical. Their tests are now pinned to protocol version 14, as the conventions ask when a new generation lands.

How Has This Been Tested?

Red → green (each fix's tests run first against the code without it):

1. operator_payout_tests, against the unfixed tree: all 5 fail. The payout key is not added, the new operator inherits P0, a retired identity keeps P0, and the revived height is cleared.

2. With list v2 but update_operator_identity still 0, the re-sent payout test fails with IdentityKeyAlreadyExists: the chain halt.

3. With update_operator_identity 1, all pass.

4. With the reconciliation call removed from transition_to_version_15, the 13→15 and 14→15 upgrade test fails: no Core read, stale keys kept. With it, it passes.

5. The hash-collision regression tests fail against v1 as first committed. The payout-equals-node-id case fails with "key to disable with specified ID is not found", which is the chain halt the review reproduced. The new-identity case keeps a duplicate-hash node-id key. Both pass with the fix.

6. After the bot review, three tests fail against the previous fix:

   • the collision test now requires every key to be added, including a signable payout equal to an earlier node id (9f9f…), and the previous fix left keys out;
   • the new-identity test requires its node-id key, which the previous fix dropped;
   • in the PV14 node-id test, the payout key stays disabled after the upgrade.

   With the ABCI guard removed but DRIVE_VERSION_V10 still selecting Drive v0, the collision test fails with IdentityKeyAlreadyExists. With Drive v1 and the reconciliation covering every masternode, all three pass.

7. With Drive v1's same-call de-duplication disabled, should_add_two_keys_with_one_hash_in_one_call fails with "insertion order error" (a duplicate operation in a consistency-checked batch). Restored, it passes.

8. With the new parent-tree de-duplication in apply_drive_operations 2 removed, the Drive and upgrade-block shared-hash tests fail with "insertion order error" under consistency checks. With it, they pass, and protocol 14 still refuses the checked batch, as before.

9. Rotate and restore (F2): should_take_the_payout_core_reports_for_an_operator_key_change_printed_without_one covers a new identity and a returning identity with the payout restored inside one Core height range, and a reset. It also asserts that Core is asked only about those entries. It fails before (the new identity gets no payout key) and passes with the Core read.

10. The new Core read: with ProTxHash::to_hex in the request, should_ask_protx_info_for_the_masternode_at_the_block_of_the_height (a real JSON-RPC connection) fails, because Core receives the reversed hash. With Core's form it passes. The same test reads an answer with "operatorReward": 13.37, which rust-dashcore's typed answer cannot read; the reviewer reproduced that failure against mainnet Core.

11. Owner-only rotations (bot review): two funded scenarios run through update_masternode_list at latest(). should_keep_a_returning_operators_payout_key_when_the_owner_switches_back_without_a_payout runs A → B → A (no payout) → B. should_keep_a_returning_operators_payout_key_when_the_owner_switches_back_with_a_payout runs A → B → A with a reported payout X. Each fails against the switch-back reconcile it replaces: A's payout key ends disabled (and a key for X is added), and with that assertion skipped, signing the withdrawal fails with PublicKeyIsDisabledError. With the fix, A's payout key stays enabled, no key for X is added, and a withdrawal signed with A's key executes. The switch-back test and the v1 unit test for an existing identity fail the same way before and pass after.

New tests:

• Payout set, changed, cleared on a key change, and with a key change.
• A switch back to a retired identity, with and without a payout (TRANSFER keys kept until the next payout change while it is current, which reconciles them); funded owner-only rotations (A → B → A without a payout → B, and A → B → A with a payout) after which A can still withdraw; a re-sent payout; the revived height kept; a payment-only diff leaving the state clean; payout and node id colliding with other keys' hashes.
• V24 taken from the Core fork record through update_core_info (recorded earlier, in this block, not active; Core is asked only by the record step).
• v1 units: idempotence, a clear, two keys added in one update, a key change to new and existing identities, a missing identity.
• Reconciliation units: stale payouts fixed on current identities, evonodes included; membership mismatch, Core error and malformed answers fail.
• Drive units for add_new_keys_to_masternode_identity (consistency checks on): a hash the identity already references (fails at 14, added from 15), two keys with one hash in one call, a unique-key hash (no reference at 14 and 15).
• A guard that every protocol version selecting update_operator_identity 1 selects Drive add_new_keys_to_masternode_identity 1 or later.
• Several identities adding keys of one new hash in one batch, in Drive and in the upgrade block, with consistency checks on and off; an identity at the last key id reconciling without a new id; estimates counting one reference per hash.
• Upgrade block: from 13 and from 14; the upgrade to 14 does not reconcile; the block's own diff after the reconciliation (key change, payout, removal, addition); a retried round.
• A 1-14 freeze test of the selected generations.

The six operator-key-encoding scenarios now also run at 15, with V24 recorded the way update_core_info 1 records it. The latest() tests that assert the old semantics run at 13 and 14. The mainnet fixture tests (test_update_masternode_list, should_build_the_validators_earlier_binaries_built_from_mainnet_masternode_lists) pass at 13 and at latest.

Ran locally:

• cargo test -p drive-abci --lib: 4554 passed, 17 ignored, after the F2 fix (before the merge of v5.1-dev's latest three commits; after it, core_based_updates, protocol_upgrade, identity_create and the shield nullifier tests pass, 495). Earlier: 4536 passed, 17 ignored, and 2 failed. The 2 failures were two shield tests that upgrade from 13 and needed a Core answer. I fixed them after that run's binary was built, and a re-run of those two plus core_based_updates and protocol_upgrade passed (227). After merging v5.1-dev (fix(drive-abci)!: re-enable the voter key of the address a masternode returns to (PV15) #5768), core_based_updates and protocol_upgrade pass again (221).
• the full strategy-test binary (RUST_MIN_STACK=4194304): 124 passed, 4 ignored, before and after the strategy mock change and after each round of review fixes.
• cargo test -p drive --lib: 4358 passed, 6 ignored.
• cargo test -p platform-version: all pass.
• CI-style clippy (--all-targets --all-features --locked -- --no-deps -D warnings) on drive-abci and platform-version: clean. cargo fmt --all --check: clean.
• After the protx info startup probe was dropped: rpc::core, core_based_updates and protocol_upgrade pass (245), CI-style clippy on drive-abci (all features) and cargo fmt --all --check are clean.
• After merging v5.1-dev (feat(platform): price storage refunds at the storing epoch's rate and drop the fee history map #5798's apply_drive_operations signature, the DashPay 14→15 upgrade test, PV15 notes renumbered): cargo test -p drive-abci --lib with CI's RUST_MIN_STACK=4194304: 4579 passed, 17 ignored; rs-drive identity::update and apply_drive_operations: 71 passed; CI-style clippy on drive, drive-abci and platform-version and cargo fmt --all --check: clean.
• After the switch-back fix for owner-only rotations: cargo test -p drive-abci --lib with RUST_MIN_STACK=4194304: 4580 passed, 17 ignored; cargo clippy -p drive-abci --all-targets and cargo fmt --all --check: clean.
• After the switch back stopped touching an existing identity's TRANSFER keys whatever the payout: cargo test -p drive-abci --lib with RUST_MIN_STACK=4194304: 4581 passed, 17 ignored; cargo clippy -p drive-abci -p platform-version --all-targets and cargo fmt --all --check: clean.

A multi-agent code review covered consensus determinism, upgrade-block failure modes, versioning and in-place rules, and tests. Its must-fixes are folded in: the hash-collision chain halt, a stale book paragraph, broken shield tests, and missing tests.

Breaking Changes

Consensus change at protocol version 15: operator payouts follow Core's diffs, an operator key change printed without a payout reads the payout from Core (protx info, which needs the dashmate whitelist migration and a Core restart after it), operator identities' TRANSFER keys are reconciled with them, and the first block of protocol version 15 reads Core's full masternode list. The Rust signature of perform_events_on_first_block_of_protocol_change gains a parameter and a CoreRPCLike bound. Protocol versions 1 to 14 are unchanged.

Out of scope

• A payout cleared by a ProUpServTx with an empty script, without an operator key change, is still invisible in protx listdiff (pre-existing, spec F3). The next printed payout heals it.

Open items

• Rehearse the reconciliation on live state before release. Load a testnet node's and a mainnet node's stored platform state, call protx listdiff 1 h, and check four things: membership, that every entry parses, the correction count, and that every current operator identity exists (all of them are now reconciled, and a missing one fails the block). Also time the identity work. A membership mismatch or a parse error fails the upgrade block on every node, and the masternode list is outside the app hash, so a past divergence would not have shown.
• Withdrawal keys the upgrade disables. The upgrade block disables every enabled TRANSFER key that Core's payout does not grant, even where the stored payout already equals Core's (for example, a key inherited through a v0 switch). That is intended, but count these on the snapshot, since such identities may hold balances.
• RPC timeout headroom. The Core RPC client times out after 15 s and retries. The measured cold call is 4.45 s; measure on minimum-spec evonode hardware.
• Dashmate tests not run locally. The new migration test needs a wasm-dpp build here; CI's "JS packages (dashmate) / Tests" runs it.
• CheckTx may wait. For those seconds, CheckTx calls that need Core (instant lock verification) wait behind the full-list call on the shared Core connection.
• Possible rust-dashcore follow-up: its typed get_protx_info sends ProTxHash::to_hex() (byte-reversed against Core's form), and its ProTxInfo reads operatorReward as an integer, while Core prints a decimal. Drive calls protx info directly and reads only state; with those fixed upstream it could use the typed client again.
• Possible dashpay/dash follow-up: a lossless protx listdiff that prints the final operator payout whenever it prints an operator-key change, including unchanged payouts and explicit clears, would make the protx info read unnecessary at a later protocol version.
• Not done (possible follow-up): since the upgrade block now reads Core anyway, it could also close the V24 record's window in the same block.
• Pre-existing and unchanged: a P2SH operator payout becomes an ECDSA_HASH160 key nobody can sign, and an evonode reset leaves a zero platform node id key (Q6). Neither affects balances.

Explanation

The title "fix(drive-abci)!: follow operator payout changes and repair operator keys at protocol 15" matches the main change. The PR adds protocol-version-15 handling that follows Core operator payout changes through masternode list updates, reconciles operator payouts and TRANSFER keys at the PV15 activation block, and adds Drive key-hash handling. The title names the drive-abci scope and the protocol version. It omits the Drive key-hash change and the dashmate whitelist migration, which is expected for a short title. The title is 88 characters, slightly above a typical short title length, but it stays on topic.

Full details: Linked Issues check

Explanation

Issue #5440 requires a rust-dashcore decoding fix for operatorPayoutAddress and PoSeRevivedHeight, with confirmation tests for Core v23 and v24. This PR adds protocol-15 Platform handling: update_state_masternode_list_v2 applies payout data and preserves the revived height, and get_masternode_state reads only the raw state from protx info. The reviewed changes do not modify the rust-dashcore decoder or provide decoder-level v23/v24 tests. The protocol-version gating requirement is met because the new consensus behavior is selected only from protocol version 15.

Resolution

Add the rust-dashcore decoder changes for both fields and add tests for the relevant Core v23 and v24 diff forms. If the decoder fix is already present outside this PR, provide reviewable repository evidence and tests that establish both fields decode correctly at the reviewed head.

Final validation — Phase 1 + Phase 2

Verified head 3a96278 and confirmed three blocking correctness issues: ambiguous Core diffs can remove valid payout authority, the upgrade repair can skip historically disabled withdrawal keys, and hash-collision handling can discard a valid payout key. The protocol-version gating and transaction-scoped upgrade orchestration are otherwise consistent with the project conventions. All current code checks pass, with PR Hygiene pending; validation here was static, with no local builds or tests run.

- [BLOCKING] packages/rs-drive-abci/src/execution/platform_events/core_based_updates/update_masternode_list/update_state_masternode_list/v2/mod.rs:209-214: Resolve ambiguous payout omissions instead of inferring a clear
  An omitted payout does not establish that the target Core state has no payout. Dash Core v23.1.3's `protx_listdiff` calls `baseBlockMNList.BuildDiff(blockMNList)`, and `CDeterministicMNStateDiff` includes a field only when its endpoint values differ. Starting at `(operator A, payout P)`, rotate to B and let B restore P before Platform next advances its Core height. The resulting diff reports B but omits the payout because both endpoint payouts are P. Platform permits multi-height advances, so this branch fabricates `Some(None)` for a valid history. The identity update then creates B without a TRANSFER key, or disables B's existing TRANSFER keys when B names a returning identity, despite Core authorizing P. Re-sending unchanged P does not generate a payout change to repair it.

  The same omission also hides an actual payout clear made by a ProUpServTx without an operator-key change. That direction predates this PR, but the new inference does not resolve it. Core's `CDeterministicMNStateDiff::ToJson` still emits nothing when the changed payout script is empty, in both the inspected release and current default source. The pinned and current rust-dashcore decoders already support an explicit empty-string clear; they cannot reconstruct information Core omits.

  Resolve ambiguous updates against authoritative state at the target chain-locked height rather than interpreting omission as a clear or blindly retaining the old payout. Add regressions for rotation followed by restoration of the same payout within one queried interval and for a service-update payout clear. The serialization repair belongs in dashpay/dash; if deferred, link a tracking issue or PR for explicit clears and a recorded-response regression. rust-dashcore #1179 documents the limitation but does not fix Core's output, and corrected output must be consumed at a protocol boundary.

- [BLOCKING] packages/rs-drive-abci/src/execution/platform_events/core_based_updates/reconcile_operator_payouts_with_core/mod.rs:115-117: Check identity keys even when the stored payout already matches Core
  Payout equality does not establish the historical identity-key invariant asserted in this method's documentation. Under PV14, an evonode with stored payout P can change its platform node ID to P and subsequently change the node ID again without changing the payout. `update_operator_identity_v0` identifies node-ID keys solely by `key.data()`, without checking purpose or key type. The first update reuses the existing TRANSFER key as the matching node-ID key; the second disables that TRANSFER key because its bytes match the old node ID P. Both Platform's stored payout and Core's payout remain P throughout.

  This filter excludes that identity from the one-time repair, leaving its valid withdrawal key disabled after the upgrade. Payment-only diffs do not invoke operator-key reconciliation, so routine subsequent blocks do not heal it. This is directly within the new migration's responsibility to repair current operator keys, rather than a request to change historical execution.

  Inspect and reconcile current operator identities independently of whether their cached payout bytes need changing. Keep the optimization of rewriting masternode-list entries only for actual payout changes. Add a PV14-to-PV15 regression that performs the node-ID collision sequence and verifies that P's TRANSFER key is re-enabled.

- [BLOCKING] packages/rs-drive-abci/src/execution/platform_events/core_based_updates/update_masternode_identities/update_operator_identity/v1/mod.rs:60-67: Resolve reverse-index collisions in Drive instead of omitting payout keys
  Holding a hash is not equivalent to holding an enabled key authorized for the requested purpose. For example, choose a signable P2PKH payout H that was previously used as the identity's platform node ID, then change the node ID and later set the payout to H. The disabled SYSTEM/EDDSA node-ID key still contributes H to `held_hashes`. Payout reconciliation disables the previous TRANSFER key, but this guard refuses to add H's ECDSA_HASH160/TRANSFER key. Core stores a valid payout while Platform leaves the identity without enabled withdrawal authority. The collision tests currently accept omission rather than asserting that the authorized payout remains usable.

  The underlying restriction is Drive's non-unique hash-to-identity reference insertion: `insert_non_unique_public_key_hash_reference_to_identity_operations_v0` rejects an existing `(hash, identity_id)` reference. That secondary index does not require removing the distinct purpose-specific key itself; masternode identity creation already stores keys without registering those external references. The book's “Where code goes” assigns index maintenance and GroveDB operations to rs-drive, so compensating for this storage restriction by dropping authority in ABCI crosses the ownership boundary as well as breaking withdrawals.

  Add protocol-15-selected Drive handling that reuses existing hash-to-identity references, including references queued within the same batch, while preserving distinct purpose-specific keys. ABCI should reconcile Core's authority without discarding the payout key. Add a regression using a signable payout equal to a disabled node-ID hash and assert an enabled TRANSFER key, not only successful block execution.

Re-review — Final validation — Phase 1 + Phase 2

At head 32ff7a4, the prior key-omission and incomplete-reconciliation findings are fixed, but two blockers remain: ambiguous payout omissions can revoke valid withdrawal authority, and shared payout hashes produce duplicate index-tree operations across identities. This was a static verification; no builds or tests were run. Current CI reports no failed code checks, with Rust workspace tests and the JS build still pending; wasm32, Kotlin, and Swift schema checks passed.

- [BLOCKING] packages/rs-drive/src/drive/identity/update/methods/add_new_keys_to_masternode_identity/v1/mod.rs:42-43: Deduplicate hash-index parent trees across the complete Drive batch
  `referenced_hashes` covers only one identity operation, while the non-unique hash parent tree is shared across identities. Consider two masternodes registered without payouts whose operators set the same previously unindexed payout H before PV15. Earlier protocols ignore those payout changes, so reconciliation queues an `AddNewKeysToMasternodeIdentity` operation for each identity. `apply_drive_operations_v2` lowers both operations before applying either; both calls see H absent and independently queue the same parent-tree insertion through `insert_non_unique_public_key_hash_reference_to_identity_operations_v0`, alongside their distinct identity leaves.

  Neither the subsequent alias coalescing nor the low-level batch conversion removes these parent duplicates. Both pinned and current GroveDB consistency checkers reject identical repeated operations. Consequently, `batching_consistency_verification=true` makes `grove_apply_batch_with_add_costs_v0` return `GroveDBInsertion("insertion order error")`, preventing that validator from executing or replaying the mandatory upgrade block. The default false setting skips this rejection, so this is configuration-dependent execution failure, not an unconditional default-network halt. Ordinary PV15 diffs that add one fresh shared payout to two existing identities can reach the same path.

  Track pending hash-parent creation across the complete version-selected Drive batch and emit the parent once while retaining both identities' keys and distinct `(H, identity_id)` entries. Keep index maintenance in Drive rather than suppressing keys or references in ABCI. Add a two-identity Drive regression and an upgrade-reconciliation regression with a shared fresh payout, exercising both consistency settings; the existing same-call test covers only one identity operation.

  (existing thread: https://github.com/dashpay/platform/pull/5775#discussion_r4479658908)
  An omitted payout is not authoritative evidence of a clear. Dash Core v23.1.3's `protx_listdiff` compares endpoint lists, and `CDeterministicMNStateDiff` sets the payout bit only when the endpoint scripts differ. Starting at (A, P), rotating to B, and restoring P before the target height therefore reports B without a payout. This branch converts that valid history into `Some(None)`.

  This also regresses returning identities, rather than merely leaving a new identity incomplete: if retired B already holds an enabled TRANSFER key P, `reconcile_operator_payout_keys_v1` disables it even though Core authorizes P. The previous generation's returning-identity path retained that key. Accepting F2 because nobody gains unauthorized access does not address this loss of withdrawal access to B's existing balance; changing to a different payout is an additional on-chain recovery operation.

  Resolve the target payout from authoritative chain-locked state before reconciling authority, or consume corrected Dash Core output at the protocol boundary. The Core repair must report the target payout whenever an operator-key change is reported, including unchanged nonempty payouts and explicit clears. Printing empty-script clears alone cannot fix equal endpoints because their payout bit is never set; the current Core default source retains that endpoint comparison. No concrete follow-up is linked in the supplied discussion, and tracking alone would not remove this newly introduced regression. Add a multi-height rotation/restoration regression that returns to B and asserts that its Core-authorized P key remains enabled. This request does not include the separate pre-existing service-only payout-clear issue.

209-215: Minor · Potential issue · Heavy lift

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

Payout clearing is inferred only from a surviving operator-key change. Because the supplied contract says Core omits an emptied payout, an aggregate diff that hides an intervening operator-key reset may leave Platform's previous payout and TRANSFER key authorized.

Platform can keep payout P and its enabled TRANSFER key even though Core's payout is empty.

This can occur when: Between two Platform-observed Core heights, operator key A changes to B and back to A, clearing payout P, with no replacement payout. The resulting diff omits the net-unchanged key, or key normalization drops it.

Re-review — Final validation — Phase 1 + Phase 2

Verified the complete diff at a20b9e4: the five prior blocking findings are addressed, and no additional blocking defect was confirmed. Two non-blocking suggestions remain to establish tracked upstream ownership for the Dash Core payout-reporting limitation and rust-dashcore RPC defects. This was a static review; current CI shows all reported code checks passing, with only PR Hygiene pending, and the supplied base drift reports no conflicts.

- [SUGGESTION] packages/rs-drive-abci/src/rpc/core.rs:567-575: Track the protx-info wire-contract repair in rust-dashcore
  This adapter safely fixes Platform's immediate lookup, but it bypasses two defects in the shared RPC client. Both pinned rust-dashcore c9aeac0d0dcb and inspected default 6bb43e15b42d still send protx_hash.to_hex() from get_protx_info and declare ProTxInfo.operator_reward as u32. ProTxHash's forward display differs from that inner-hash serialization, and Core accepts fractional rewards, so other consumers retain the request-hash and response-decoding failures avoided here.

  Link a dashpay/rust-dashcore issue or PR to correct get_protx_info's hash serialization and provide decimal-compatible response decoding or a typed state-only API. Include the request-parameter and fractional-reward regressions at that shared boundary. rust-dashcore #1179 addresses list-diff decoding, not these defects. Keeping the safe projection in DefaultCoreRPC while an upstream repair is pending is reasonable; the missing piece is a tracking reference, not another local workaround.

  (existing thread: https://github.com/dashpay/platform/pull/5775#discussion_r4490341024)
  The open-items bullet acknowledges the correct owner, but there is still no linked dashpay/dash issue or PR tracking the repair. The historical lookup correctly resolves operator-key changes; it remains necessary because Core's endpoint diff omits restored-to-original payouts, while CDeterministicMNStateDiff::ToJson omits empty payouts in both v23.1.3 and current develop. A service-only clear therefore still bypasses this lookup and can leave the previous TRANSFER authority enabled.

  Core's current protx_listdiff already enriches address information from the target masternode state, so payout enrichment can likewise be repaired at the RPC boundary without changing historical binary diff semantics. Link a dashpay/dash follow-up covering explicit clears and the final payout alongside reported operator-key changes, with response regressions for rotate-and-restore and service-only clears. Platform should adopt the corrected output at a future protocol boundary. This requests tracked upstream ownership before deferral, not implementation of the separate Core repair in this PR.

Re-review — Final validation — Phase 1 + Phase 2

At 56e4dc4, the five prior blocking findings are fixed, but returning-identity reconciliation introduces a funds-denial path: an owner-only operator rotation can disable a former operator's legitimate withdrawal authority over accrued credits. The two upstream-tracking suggestions remain valid and untracked. This was a static review; current code checks pass, including Rust workspace, Dashmate, browser, and end-to-end tests, with review and hygiene gates pending.

- [BLOCKING] packages/rs-drive-abci/src/execution/platform_events/core_based_updates/update_masternode_identities/update_operator_identity/v1/mod.rs:203-209: Prevent owner-only rotations from freezing a retired operator's balance
  This reconciliation disables legitimate withdrawal authority when a retired operator identity is selected again without a payout, although selecting that operator key does not require its holder's authorization. I verified that Dash Core v23.1.3 and current develop authenticate CheckProUpRegTx with the masternode owner's key, not the selected operator's key; changing the operator key resets the operator payout.

  Across separate Platform updates, an owner can let operator A accrue credits in identity I_A with payout key P, rotate to B, select A's publicly known BLS key again without setting a payout, and then rotate back to B. The first departure correctly preserves P. On the return, the historical lookup supplies Some(None), and this call disables every enabled TRANSFER key in I_A. The final departure preserves that disabled state, stranding A's earlier credits. Disabled signing keys are rejected by identity-signature validation, and the operator identity's SYSTEM/CRITICAL keys cannot authorize an identity update or replace its TRANSFER authority. A cannot restore the payout through Core after B becomes current without the owner's cooperation.

  The historical returning-identity path retained the earlier payout authority when no replacement was supplied. The new switch-back regression instead asserts its removal on an unfunded identity, so it does not establish that accrued funds remain spendable. Preserve authority over previously accrued operator credits without restoring the previous-operator inheritance bug—for example, require the affected operator's authorization for destructive reconciliation or separate activation-specific authority and balances. Add a funded A→B→A-without-payout→B regression that verifies A can still spend its earlier credits.

  (existing thread: https://github.com/dashpay/platform/pull/5775#discussion_r4491037471)
  The displayed-hash request and state-only response projection safely protect this Platform path. However, both pinned rust-dashcore c9aeac0d0dcb and inspected default c7bb2cedd596 still serialize get_protx_info's hash with to_hex() and declare ProTxInfo.operator_reward as u32. Other consumers of the shared client therefore retain the request-hash and fractional-reward decoding failures that this adapter avoids.

  The Open items entry identifies the correct owner, but it contains no tracking reference, and the upstream issue/PR searches did not identify a matching repair. Link a dashpay/rust-dashcore issue or follow-up/draft PR covering Core-compatible hash serialization and decimal-compatible decoding or a typed state-only API, with request-parameter and fractional-reward regressions at that boundary. The local projection can remain unchanged; the upstream repair needs a tracking reference before it can be deferred.

  (existing thread: https://github.com/dashpay/platform/pull/5775#discussion_r4490341024)
  The historical state lookup correctly resolves operator-key changes whose payout is omitted, but it compensates for missing information in dashpay/dash's RPC contract. I verified that released Core v23.1.3 and current develop emit operatorPayoutAddress from CDeterministicMNStateDiff::ToJson only when ExtractDestination succeeds, omitting empty payouts. Endpoint comparison also cannot include a payout restored to its original value during a rotation. The rust-dashcore decoder already supports explicit clears, so another decoder change cannot recover this information.

  The Open items entry records the intended follow-up without linking an issue or PR. Link a dashpay/dash tracker for explicit payout clears and target-payout reporting alongside operator-key changes, enriching the RPC response from the target list without changing historical binary-diff semantics. Include recorded-response coverage and consume corrected semantics at a later Platform protocol boundary. The tracker should also cover the pre-existing service-only clear, which skips this lookup and can leave the former TRANSFER authority enabled. This requests tracked upstream ownership, not implementation of the separate Core repair here.

Assert the second identity’s stored payout key.

The test checks the second identity’s hash reference, but not its key. A batching regression could preserve the reference while dropping the key and still pass. Fetch other_identity_id and assert that key 1 matches the added payout key.

@packages/rs-drive-abci/src/execution/platform_events/core_based_updates/reconcile_operator_payouts_with_core/mod.rs:
- Around line 135-138: The reconciliation mapping in updated_mns uses
operator_payout_diff and can disable a payout key without a corresponding Core
payout restoring it. Update the reconciliation behavior so it preserves an
operator’s existing withdrawal authority when an owner rotates A → B → A before
PV15 without restoring a Core payout; establish the appropriate existing state
or rule to distinguish that case without weakening other payout updates.

Review comments at
@packages/rs-drive-abci/src/execution/platform_events/core_based_updates/update_masternode_identities/update_operator_identity/v1/mod.rs:
- Around line 107-109: Move the empty-key validation for old_identity_keys
before the operator-key-change branch in the update_operator_identity flow, so a
switch cannot create the target identity and succeed when the old identity has
no keys. Preserve the existing corrupted-state handling and normal
identity-switch behavior for non-empty keys.
- Around line 211-239: Update the existing-identity restoration logic around
identity_keys to find the matching BLS key and add its key ID to
changes.to_re_enable when it is disabled. Preserve the existing platform-node-ID
handling and avoid re-enabling unrelated keys.

Review comments at
@packages/rs-drive/src/util/batch/drive_op_batch/drive_methods/apply_drive_operations/v2/mod.rs:
- Around line 307-311: Update the deduplication logic around operations.retain
and inserted so it removes only identical tree-creation inserts when no
intervening write targets the same key. Preserve conflicting writes in order,
including a delete after an insert for the same hash tree, so the final delete
is not discarded.

Review comments at
@packages/rs-platform-version/src/version/drive_versions/v10.rs:
- Line 125: Update the v10 handling of add_new_keys_to_masternode_identity so
operations in the same batch that add keys with the same new hash to one
identity produce only one identity-reference insert, while retaining both keys
and preserving consistency verification.

Preserve withdrawal authority during upgrade reconciliation.

If an owner rotates A → B → A before PV15 without restoring a Core payout, reconciliation disables A’s payout key. After the owner rotates away, A cannot independently withdraw its accrued credits or restore the key. Avoid removing that withdrawal authority during reconciliation.

Check the old operator identity before switching.

If the old operator identity has no keys, an operator-key change can create the target identity and return success instead of reporting corrupted state. Move the existing empty-key check before the identity-switch branch.

around lines 107 - 109:
Move the empty-key validation for old_identity_keys before the
operator-key-change branch in the update_operator_identity flow, so a switch
cannot create the target identity and succeed when the old identity has no keys.
Preserve the existing corrupted-state handling and normal identity-switch
behavior for non-empty keys.

Re-enable the returning operator’s BLS key.

When an operator changes from A to B and back to A, A’s BLS key remains disabled. Document writes that reference that key are then rejected. Re-enable the matching BLS key when restoring an existing operator identity.

Preserve conflicting writes when deduplicating hash trees.

With consistency checking disabled, a raw delete(H), insert(H), delete(H) batch loses its final delete and can retain H. Deduplicate only identical tree-creation inserts that have no intervening write to the same key.

Coalesce identity-reference inserts across the batch.

If two operations add keys with the same new hash to one identity, both queue the same identity-reference insert. With consistency verification enabled, the batch fails instead of storing both keys. Coalesce those inserts across operations while retaining both keys.

Re-review — Final validation — Phase 1 + Phase 2

At e80e282, the ordinary switch-back guard preserves withdrawal authority, but the protocol-15 reconciliation still permits the same owner-only balance freeze across activation. Five other prior defects are fixed; the two upstream repair-tracking suggestions remain open. Validation was static only: Rust workspace, WASM, JS and image checks remained pending when inspected, while the Dashmate helper image failed because sccache could not read its cache storage, an infrastructure failure unrelated to this diff.

- [BLOCKING] packages/rs-drive-abci/src/execution/platform_events/core_based_updates/reconcile_operator_payouts_with_core/mod.rs:135-138: Prevent owner-only rotations from freezing a retired operator's balance
  The returning-identity guard fixes ordinary PV15 updates, but the upgrade caller still bypasses it. This mapping includes every current operator and turns an empty Core payout into `operator_payout_diff(None)`, which sets `pub_key_operator: None` and `operator_payout_address: Some(None)`. The updater therefore takes its same-identity branch and disables every enabled TRANSFER key, rather than reaching the protected switch-back branch.

  A reachable boundary sequence is: A holds accrued credits and its legitimate payout key P; across separate PV14 updates, the owner rotates A → B → A without setting another operator payout. The historical updater preserves P on A's returning identity, while Core's registrar rotation clears the payout. Core v23.1.3's `CheckProUpRegTx` authenticates that rotation with the owner's signature, not A's. The first PV15 reconciliation then disables P. A departure to B in the upgrade block's subsequent Core diff, or a later block, leaves A retired without withdrawal authority. An empty reward-share document count does not exclude funded identities: identity-credit transfers accept any existing recipient identity.

  Your latest-only funded regression proves the ordinary switch-back repair, but leaving the upgrade reconciliation unchanged preserves this activation-time route to the same freeze. Preserve legitimate withdrawal access over pre-upgrade credits without reinstating previous-operator inheritance, and add a funded PV14 A → B → A-without-payout → PV15 reconciliation → B regression that executes A's withdrawal afterward.

- [SUGGESTION] packages/rs-drive-abci/src/rpc/core.rs:567-575: Track the protx-info wire-contract repair in rust-dashcore
  (existing thread: https://github.com/dashpay/platform/pull/5775#discussion_r4491037471)
  The state-only adapter safely avoids the immediate failure, but it compensates for defects in dashpay/rust-dashcore's shared RPC boundary. Both pinned c9aeac0d0dcb and the supplied upstream default 33ae18c4a36f still serialize `protx_hash.to_hex()` in `get_protx_info` and declare `ProTxInfo.operator_reward` as `u32`. Other typed-client consumers therefore retain the request-hash and fractional-reward decoding failures that this adapter avoids.

  The Open items entry acknowledges ownership, but neither it nor the supplied discussion links an upstream repair; the inspected open issue and PR searches did not identify one. Link a dashpay/rust-dashcore issue or follow-up PR covering Core-compatible hash serialization and decimal-compatible response decoding, or a typed state-only API, with request-parameter and fractional-reward regressions. This needs a tracking reference before it can be deferred; the safe local adapter can remain.

  (existing thread: https://github.com/dashpay/platform/pull/5775#discussion_r4490341024)
  The historical lookup is correctly placed in node-side orchestration, but it compensates for information missing from dashpay/dash's RPC output. In both inspected v23.1.3 and develop sources, `CDeterministicMNStateDiff::ToJson` omits an empty operator payout through its `ExtractDestination` guard, while `protx_listdiff` constructs endpoint differences. Consequently, a payout restored to the same endpoint value is also omitted unless the RPC enriches the operator-key change with the target payout. The pinned and default rust-dashcore decoders already support explicit clears and cannot reconstruct this missing information.

  Recording a possible Core follow-up does not provide upstream tracking, and the inspected listdiff issue concerns operator-key encoding rather than payout reporting. Link a dashpay/dash issue or follow-up PR for explicit payout clears and target-payout reporting alongside operator-key changes, including unchanged endpoint payouts and the pre-existing service-only clear. Include recorded-response coverage and consume corrected output at an appropriate Platform protocol boundary. This requests tracked ownership, not implementation of the separate Core repair here.
