📝 WalkthroughWalkthroughThis change adds protocol v14 contract-scoped authentication keys. It defines scope data and permissions, validates scoped keys during registration and execution, preserves scope bytes across persistence and FFI boundaries, and exposes the feature through Kotlin, Swift, Rust, and WASM SDKs. ChangesScoped authentication
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The current changes can invalidate replay of previously accepted shielded identity transitions and introduce scoped-key failures across Kotlin/JNI and Swift workflows. These compatibility and integration defects should be fixed before merge. Possibly related PRs

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.

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.

- [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.

🟡 Suggestion: 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.

🟡 Suggestion: 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.

Issue being fixed or feature implemented
Applications such as Yappr need a browser signing key that can write application documents and pay their token fees without granting control over the rest of the user's identity. This adds contract-scoped authentication keys enforced by Platform beginning with protocol 14.
What was done?
There are no per-key spending budgets: a compromised key can exhaust balances through fees and permitted operations until expiry or revocation. Yappr application changes and network activation are separate from this Platform/SDK change.
How Has This Been Tested?
cargo clippy --workspace --all-targets --all-features --locked -- --no-deps -D warnings), plus workspace formatting checks.Private-key signing regression tests also cover wrong contract/type/action, non-batch rejection, successful scoped signing, and unchanged unscoped signing.
Coverage follow-up adds shielded creation through the public protocol dispatcher (including charged fallback on invalid bounds), multi-contract reference refresh after revocation, all 11 standalone token permissions in isolation, scope-size and empty-permission boundaries, and legacy P2PKH/P2SH shielded preimage compatibility across protocols 13 and 14. These targeted tests and strict DPP/Drive ABCI all-target/all-feature Clippy pass locally. No production behavior or coverage exclusions were changed by this follow-up.
A live rolling-upgrade rehearsal was not run.
