feat(platform)!: key references on the writer's own identity (PV14)

[QuantumExplorer]

Issue being fixed or feature implemented

Today an identityPublicKey reference lives on an identifier property (the identity) and names, through keyIdProperty, an integer property carrying the key id. The moderation charters contract (#4898) needs the inverse: joinRequest.senderKeyId is the owner's encryption key the shared secret of the encrypted message is derived from, so the reference belongs on the key id itself and the identity is named by the declaration. This adds that form at protocol version 14, with identityProperty naming the writer ($ownerId), the document's creator ($creatorId) or an identifier property of the same document type:

"senderKeyId": {
  "type": "integer", "minimum": 0, "maximum": 4294967295,
  "refersTo": { "type": "identityPublicKey", "identityProperty": "$ownerId" },
  "position": 3
}

A document of such a type carries the key id alone; the identity is its owner. With that property on a joinRequest document type, the writer 5HpKEK... (the identity that signs the create transition) declares that key 3 of its own identity is the encryption key the message's shared secret is derived from:

{
  "$id": "8yzQXq…",
  "$ownerId": "5HpKEK…",
  "$type": "joinRequest",
  "$revision": 1,
  "charterId": "Ct7Vq2…",
  "encryptedMessage": "b64…",
  "senderKeyId": 3
}

Consensus fetches key 3 of identity 5HpKEK… (one key read; the identity's existence is already proven by the transition) and refuses the write, paid, if that key does not exist (ReferencedIdentityKeyNotFoundError, 40123) or is disabled (ReferencedIdentityKeyDisabledError, 40124). A reader resolves the key as identity($ownerId).key(senderKeyId). Every replace of the document re-checks it, so if the document changes hands the new owner has to set senderKeyId to one of its own keys, and a replace by the original owner while key 3 has meanwhile been disabled is refused until it names another key. Omitting senderKeyId is not validated (whether it may be absent is the type's required list).

What was done?

• Model (rs-dpp): a new DocumentPropertyType::KeyIdWithReference(KeyReferenceIdentityProperty) variant, appended, over KeyIdReference: the identity source (OwnerId for "$ownerId", CreatorId for "$creatorId", Property(path) for an identifier property of the same document type) plus the same IdentityKeyReferenceRequirements the identifier form takes. Every integer arm that U32 takes (sizes, encoding, decoding, random values, sanitizing, is_integer, Drive query typing and operators, agreement value kinds) takes it too, so the bytes and queries of a key id are unchanged by the declaration. DocumentPropertyReferenceTarget and the contract wire format are untouched: the reference is derived from the schema, so contracts without the form serialize as before. Chosen over a variant of the target because the reference has to live on an integer property, and a second channel on DocumentProperty would have left every existing match arm silently blind to it.
• Parser (apply_property_reference v0, edited in place as PV14 is unreleased): identityProperty is admitted only with type: identityPublicKey, only on an integer property declaring exactly the key id range (minimum 0, maximum 4294967295, read from the schema so the rule holds whatever the contract's sized integer types setting), never together with keyIdProperty or propertyAgreement, and only as $ownerId, $creatorId or a property path of 1 to 256 characters; a path naming a property that itself carries an identityPublicKey reference is refused at registration. Every other refersTo form stays identifier-only. Below PV14 the keyword is ignored, as the whole of refersTo is. identityProperty is a refersTo sub-key, not a doctype-level keyword, and is on neither stray-key list of the meta-schema v0 census.
• Meta-schema v3 (edited in place): identityProperty added as $ownerId, $creatorId or a property path; an identityPublicKey reference requires exactly one of keyIdProperty and identityProperty; the dependentSchemas rule keeps refersTo identifier-only except when identityProperty is present, in which case the property must be "type": "integer", "minimum": 0, "maximum": 4294967295.
• Consensus (document_reference_validation v0, drive-abci): the key id form reads the key id from the property itself and resolves the identity from the declaration: the transition's owner for $ownerId, the creator for $creatorId (the writer on a create, the stored creator on a replace, which the validator now receives from the action), or the named property's value for a path (a key id set while it is unset is refused with 40125). The owner and creator are already proven to exist, so the key fetch is the only read; the check both forms share (validate_referenced_identity_key_v0) refuses a missing key with ReferencedIdentityKeyNotFoundError (40123) and a disabled one with ReferencedIdentityKeyDisabledError (40124), paid, as the identifier form does. No new error. An unset key id is not validated (the required list decides whether it may be absent). A replace re-validates $ownerId touched or not, as the $ownerId writer gate does, since the writer may not be the one who wrote the key id; $creatorId when the key id changed; a path when the key id or the named property changed (a transfer itself is never checked: the reference governs writing, not holding). Registration refuses $creatorId on a document type that does not record creator ids, a path that does not name an identifier property, and, in either direction, a pair declared from both sides (40125). Registration-time validation needs nothing for this form (there is no sibling to check).
• Update rules: a refersTo on the key id property is an incompatible change to add, remove or alter, like the rest of refersTo; the schema differ already flags it, so this is a test.
• Clients: wasm-dpp2 reports { type: 'identityPublicKey', identityProperty } on the reference surface, with the TypeScript union split into the two forms. Swift and Kotlin are out of scope for this PR.
• Docs: item 30 of the v14 changelog (25 to 29 went to typed arrays, distinctFrom, encryptedFor, the word-character name rule and keyRequirements, feat(dpp)!: typed scalar arrays in document schemas (PV14) #4922, feat(platform)!: distinctFrom on identifier properties (PV14) #4917, feat(platform)!: encryptedFor envelope declaration on byte properties (PV14) #4919, fix(dpp)!: typed array review fixes: hyphenated list paths, element constraints, untrusted lists, Swift refusal #4924 and feat(platform)!: keyRequirements on identity key references (PV14) #4918, merged in; v4.2-dev numbered encryptedFor and the name rule both 27, this branch renumbers the name rule to 28); a "Document References (refersTo)" section in the book's Documents chapter.

keyRequirements (#4918, merged in) apply to this form exactly as to the identifier form: the requirement check moved into the shared validate_referenced_identity_key_v0, the registration-time boundTo rule reads both forms, the meta-schema admits the keyword under either, and wasm-dpp2 reports it on both. Tests: the key id form parses and mirrors keyRequirements, boundTo is checked on it at registration, and a create is refused with 40136 when the owner's key has the wrong purpose.

How Has This Been Tested?

• rs-dpp: parse the form on a u32 property naming $ownerId, $creatorId or a property path (with and without the meta-schema); refuse it on an identifier property, on integers outside the u32 range, together with keyIdProperty, with propertyAgreement, on other reference types and with an identityProperty that is neither a system name nor a path (parser and meta-schema each); ignored at PV13 and refused by the v2 meta-schema; the new type sizes, encodes, decodes and names exactly as U32; serde metadata; adding, removing or changing the reference on update is incompatible.
• drive-abci (fixture reference-validation-contract-owner-key.json): a create naming an existing key of the owner succeeds; a missing key id is refused with 40123; a disabled key with 40124; an unset key id passes; a replace changing the key id to a missing or disabled key is refused; a replace of another property while the referenced key was disabled in between is refused (an untouched key id is refetched) and passes while the key stays enabled; after a transfer to a receiver whose named key is disabled, a replace of another property is refused and one repointing the key id at the receiver's key passes; a nested key id property is validated at its dotted path; the fixtures register through a real DataContractCreate; registration refuses $creatorId on a type not recording creators, a path naming a missing or non-identifier property, and a pair declared from both sides. $creatorId: after a transfer the receiver may repoint the key id at the creator's key and is refused for one the creator lacks, with the creator in the error. A property path: the named identity's key is what is fetched (its disabled key is refused, the writer's is not consulted), a key id without the identity is refused, changing only the identity property re-validates, and an untouched pair is not refetched.
• wasm-dpp2: the reference spec gains senderKeyId ($ownerId) and authorKeyId (a property path) declarations and asserts identityProperty on them and its absence on the identifier form.
• Run locally: cargo check -p dpp, cargo check -p drive -p drive-abci --tests, cargo fmt --all. The targeted dpp tests (118), the drive-abci key reference tests (15), cargo check -p wasm-dpp2 --target wasm32-unknown-unknown, the CI-form clippy and the wasm spec (16) all pass on the merged tree; see the verification comment.

In-place changes to shipped generations

None. Every generation edited here (apply_property_reference v0 in dpp, the document reference validation v0 and the contract reference validation v0 in drive-abci, meta-schema v3) is selected only by protocol version 14, which is unreleased.

Breaking Changes

Protocol version 14 (unreleased) admits a new refersTo form and a new DocumentPropertyType variant; contracts and documents without it are unaffected.

📝 Walkthrough

Walkthrough

The change adds protocol v14 support for identityProperty: "$ownerId" references on u32 key ID properties. It adds schema parsing, KeyIdWithReference handling, owner-key validation, query support, WASM serialization, documentation, and tests.

Changes

Owner key document references

Layer / File(s)	Summary
Schema and document type support packages/rs-dpp/schema/meta_schemas/document/v3/document-meta.json, packages/rs-dpp/src/data_contract/document_type/..., packages/rs-platform-version/src/version/v14.rs, book/src/data-model/documents.md	Protocol v14 schemas accept identityProperty: "$ownerId" on u32 key ID properties. Parsing produces KeyIdWithReference, which retains u32 sizing, encoding, decoding, sanitization, and integer behavior.
Document state validation packages/rs-drive-abci/src/execution/validation/..., packages/rs-drive-abci/tests/..., packages/rs-drive-abci/tests/supporting_files/...	Creation and replacement validation checks the referenced owner key. Missing and disabled keys return the corresponding errors. Tests cover valid, omitted, missing, disabled, and changed key IDs.
Query and WASM reference surfaces packages/rs-drive/src/query/conditions.rs, packages/wasm-dpp2/src/data_contract/document_type_reference.rs, packages/wasm-dpp2/tests/unit/DocumentPropertyReference.spec.ts	Queries treat KeyIdWithReference as a numeric field. WASM output exposes the inverse reference with identityProperty and keeps it distinct from the identifier-property form.

Validate owner-bound key references during transfer and replace.

DocumentTransferTransitionActionStateValidationV0 does not validate document references. The transfer operation then stores the document with its new owner_id. A KeyIdWithReference(OwnerId) key ID can therefore remain valid for the old owner but invalid for the new owner.

A later replace passes Some(self.changed_data_fields()). The unchanged key-id path then skips validation, so the invalid key ID can persist. Validate the document against the new owner during transfer, and always revalidate OwnerId key references during replace.

[QuantumExplorer]

On the review finding "Validate owner-bound key references during transfer and replace" (outside the diff, so no inline thread): addressed in 132ba17, following the precedent of the $ownerId writer gate in the same validator.

• The identity of an owner key reference is the writer, transition metadata that never appears among a replace's changed fields. On a document type whose documents can change hands (transferable or a trade mode) the reference is now re-validated on every replace, so a replace by the new owner has to repoint the key id at one of its own keys. On every other type the owner is fixed for the document's life, so an untouched key id is still not refetched (the existing test keeps proving that).
• A transfer itself is not checked, as the writer gate is not: the reference governs writing, not holding. Checking at transfer would need reference validation in the transfer action for one property kind, and the next replace catches the stale key id anyway.
• Two tests transfer a document to a receiver whose named key is disabled: a replace of another property is refused with 40124, and one that repoints the key id at the receiver's enabled key passes.

• Every replace re-checks an owner key reference, touched or not, as the $ownerId writer gate does, instead of only on transferable or tradeable types: the gate encoded which transitions can move ownership into the reference validator. A transfer itself is still not checked.
• The parser reads the declared range (minimum 0, maximum 4294967295, what the meta-schema pins) rather than the inferred u32, so the rule no longer depends on the contract's sized integer types setting and the refusal names the real bounds. The propertyAgreement rule is stated once.
• Registration refuses a keyIdProperty that names a property carrying this form (ReferencedKeyIdPropertyInvalidError, 40125): one value cannot be a key of two identities.
• Tests: nested key id property under the meta-schema and at its dotted path in consensus, untouched key id refetched on replace (refused when the key was disabled in between, passes while enabled), the fixture registering through a real DataContractCreate, the double reference refused. Targeted dpp tests 119, drive-abci key reference and registration tests 29, CI-form clippy clean.

Two changes since the last round, both pushed:

identityProperty names three identity sources (e8ad128): $ownerId (the writer, re-checked on every replace), $creatorId (the document's creator, only on a document type that records creator ids, re-checked when the key id changes) and the path of an identifier property of the same document type (re-checked when the key id or that property changes; a key id set while the property is unset is refused with 40125). Registration refuses $creatorId on a type not recording creators and a path that does not name an identifier or that names one carrying its own identityPublicKey reference. The validator now receives the creator id from the action.

keyRequirements (#4918) apply to this form (merge 2a133c3): KeyIdWithReference carries a KeyIdReference, the identity source plus the same IdentityKeyReferenceRequirements as the identifier form. The requirement check moved into the shared validate_referenced_identity_key_v0, the registration-time boundTo rule reads both forms, the meta-schema admits the keyword under either form and wasm-dpp2 reports it on both.

Verified on the merged tree: 180 targeted dpp tests (parser, model, update rules, boundTo), 47 drive-abci reference and registration tests, CI-form clippy, the wasm32 check, the wasm bundle and its 17 spec cases.
