Final validation — Phase 2 only (queue backlog)
Three blocking issues remain: accepted scopes can produce unreadable stored keys, and two identity-creation paths change block acceptance before protocol 14 activates. The scoped WASM object declarations also disagree with runtime values, and the new identity-update fee retention lacks a regression that observes the retained costs.

- [BLOCKING] packages/rs-dpp/src/state_transition/state_transitions/identity/public_key_in_creation/methods/validate_identity_public_keys_structure/v0/mod.rs:47-58: Reject pre-activation scopes before chargeable identity-create validation
This rejection happens too late to preserve pre-activation block acceptance for asset-lock IdentityCreate transitions. Their basic validation checks asset-lock structure and key count; this key-structure validator runs in advanced_structure/v0 after transformation into an action. Its error is converted into a PartiallyUseAssetLockAction, producing a paid failure that can remain in a proposed block. The base binary cannot decode the new ContractBounds discriminant and instead produces an unpaid decoding failure. process_proposal rejects blocks containing unpaid failures but permits paid failures, so upgraded proposers and older validators can disagree while executing protocol 13. Reject Scoped keys in an unchargeable stage before protocol 14, and add a raw identity-create regression asserting an unpaid result with no execution action or storage mutation.

- [BLOCKING] packages/rs-drive/src/drive/identity/contract_info/keys/add_potential_contract_info_for_contract_bounded_key/v0/mod.rs:248-250: Version the new authentication-key indexing behavior
The new AUTHENTICATION arm changes historical behavior for legacy bounds, not only Scoped keys. Under protocol 13, identity-create state validation does not validate contract bounds, so an otherwise valid identity creation can reach indexing with an AUTHENTICATION key whose SingleContract bounds reference an existing contract. The base implementation returns IdentityKeyBoundsError for that purpose; this implementation inserts the key and its references. The dispatcher still selects v0 for historical protocols, and process_proposal rejects internal failures while accepting successful execution. Consequently, old and upgraded nodes can disagree on a block using only legacy wire variants before protocol 14 activates. Put the new indexing behavior behind a version activated at protocol 14, preserving historical purpose rejection in both the contract-level and document-type branches.

- [BLOCKING] packages/rs-dpp/src/identity/identity_public_key/contract_bounds/authentication_scope.rs:135-140: Accepted scopes exceed the stored public-key decoder's limit
The accepted scope size is incompatible with IdentityPublicKey's existing PlatformDeserialize limit of 2000. A focused reproduction with eight contracts, each restricting type00 through type15, passes scope validation and encodes the scope to 1172 bytes. An ECDSA_HASH160 key containing that scope serializes to 1202 bytes, but IdentityPublicKey::deserialize_from_bytes returns MaxEncodedBytesReachedError because bincode's decoding budget also accounts for container allocations. When the referenced contracts and document types exist, registration validation permits the key and Drive stores its serialized bytes without checking this round trip. Key fetches, identity proof verification, and revocation subsequently depend on the failing decoder. Make the stored-key decoding budget accommodate every accepted scope, including allocation accounting rather than only wire size, and add a large-scope registration/fetch/proof/revocation regression.
In `packages/wasm-dpp2/src/data_contract/contract_bounds.rs`:
- [SUGGESTION] packages/wasm-dpp2/src/data_contract/contract_bounds.rs:89: Include undefined in scoped object optional-field declarations
ContractBounds.toObject() returns undefined for absent documentTypes and expiresAt, but this declaration promises string[] | null and bigint | null. The shared object serializer uses Serializer::new() without serialize_missing_as_null, and the generated declarations retain this mismatch. A Node probe against the generated bindings confirms that ContractBounds.Scoped([{ id }], 1).toObject() returns undefined for both fields. TypeScript consumers following the declared types can therefore pass a null check and then throw when calling .includes() or .toString(). Include undefined in the object declarations, or normalize absent fields to null during serialization, and cover omitted restrictions and expiry in the smoke test.
In `packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/identity_update/mod.rs`:
- [SUGGESTION] packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/identity_update/mod.rs:402-407: Add a regression that observes retained identity-update validation fees
This registration test uses the cached DashPay system contract, whose lookup contributes no fee, and asserts successful execution and preserved metadata rather than retained validation costs. The scoped revocation test also uses system contracts. These tests therefore do not protect the new identity_update/state/v1 behavior of retaining operations in the caller's execution context instead of discarding a local context as v0 does. Reintroducing that mistake could undercharge updates without breaking these assertions. Add a version-dispatched update regression using a non-system contract and a missing-contract paid-failure case, asserting retained validation operations or an attributable fee delta. Include a protocol-13 legacy-bounds case to pin the intentionally unchanged historical accounting.

Final validation — Phase 2 only (queue backlog)
The scoped-authentication implementation and its targeted regressions address all five previously reported issues. One blocking interoperability defect remains: the per-key decoding budget was increased for valid large scopes, but the enclosing Identity decoder still has a 15,000-byte budget, so identities containing multiple permitted scoped keys cannot be decoded through full-identity transport paths.

In `packages/rs-dpp/src/identity/identity.rs`:
- [BLOCKING] packages/rs-dpp/src/identity/identity.rs:42: Raise the enclosing Identity decode budget for valid scoped-key sets
`IdentityPublicKey` now permits a 16 KiB decoding allocation budget so a single valid maximum-shaped scope can be decoded, but the enclosing `Identity` remains limited by `#[platform_serialize(limit = 15000, unversioned)]`. Bincode's decoding budget includes container allocations, so the outer limit is consumed by the identity fields, the public-key map, and each scoped key's bounded contract/document-type collections. As a result, identities containing several otherwise valid scoped keys can be serialized but fail `Identity::deserialize_from_bytes` with `MaxEncodedBytesReachedError`. This breaks full-identity transport and fetch paths such as the unproved identity query in `packages/wasm-sdk/src/queries/identity.rs:435`, despite the feature explicitly allowing multiple scoped keys. Increase the enclosing identity budget to accommodate the permitted key set, or use a decoding path whose aggregate limit is derived from the identity's bounded contents while retaining the individual scope wire-size limit.

Addressed the full-identity decode-budget finding from review 5160356094 in commit 6a6fbd5. The new regression reproduced Regression coverage includes eight-key and 15,000-key full-identity round trips, maximum contract/type counts, disabled scoped keys, and rejection of a forged excessive key-map allocation. Validation: all 513 DPP identity-related tests pass, along with strict DPP all-target/all-feature Clippy and formatting checks. 🤖 Posted autonomously by Codex on behalf of pasta. |

63-63: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winAvoid restating the Rust scope wire limit in Kotlin.
1..2048duplicates the 2 KiB scope wire limit that Rust already enforces during registration. If Rust changes that limit, this Kotlin guard silently rejects valid scopes and the two layers drift. Prefer bounding only what Kotlin owns here, for examplesize <= 0xFFFFto protect thewriteShortlength prefix, and let Rust reject an out-of-range scope. If a client-side pre-check is required, expose the limit from Rust over the existing FFI instead of hard-coding it.As per coding guidelines for

Do not mark Identity as unversioned.
Identity is not stored in Drive. Its serialization is used for transport, and the declaration documents that it includes a version. unversioned switches PlatformSerialize to raw bincode without the version-aware path. This can change transport bytes and prevent existing consumers from decoding them. Remove unversioned and retain only the larger limit.

Issue being fixed or feature implemented
Applications need signing keys limited to selected contracts and operations. This is the Platform/Drive/DPP foundation of a two-PR stack; SDK support is in the dependent PR #4655, also sourced from
dashpay/platform.What was done?
How Has This Been Tested?
Breaking Changes
Activation requires protocol 14. DPP gains new enum variants and singular bound identifiers become optional. Native scope support requires the dependent SDK PR. Scopes have no per-key spending budget; fees and permitted operations can consume balances until expiry/revocation.
