…redSince) A contract update may now add a new required property to a document type by annotating it with requiredSince equal to the contract version the update creates. Documents are stamped (serialization format 3) with the contract version their bytes conform to, so the latest contract alone reconstructs every stamp's byte layout — no historical contract lookups anywhere: - requiredSince property keyword in meta-schema v3, parsed onto DocumentProperty behind a new apply_required_since version slot (None on pre-v14 tables, so frozen parsers stay byte-identical) - document serialization format 3: a contract-version stamp varint after the format prefix; a property whose requiredSince exceeds the stamp keeps the presence-flagged layout it was written with (DOCUMENT_VERSIONS_V4, default 3, wired into v14 only; read dispatch stays prefix-driven) - legacy formats 0-2 read and write with required_at(None) — byte-identical for every schema without annotations (all shipped data), and it keeps old-format bytes readable under a schema that later gained a required field - validate_update v1 strips top-level required from the schema diff (the indices pattern) and judges it in dedicated Rust: additions only for brand-new properties carrying requiredSince == old version + 1; removals, promotions of existing properties, system fields, and retroactive values rejected with DataContractInvalidRequiredFieldsUpdateError (10276); the differ gets a frozen requiredSince rule so tampering is a clean consensus error instead of an unsupported-keyword hard error - Drive assigns the stamp at create/replace (beside creator_id); transfers and purchases re-serialize without touching it, so grandfathered documents stay transferable; contract creation rejects requiredSince other than 1 (basic_structure v2) Grandfathered documents remain valid and readable indefinitely; a replace re-supplies full content and must include the field (lazy migration). The stamp also gives clients an explicit staleness signal when a document is stamped above their cached contract version. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Preliminary review — Codex only
The required-field compatibility design is coherent overall, but three consensus-critical gaps remain: format-3 storage estimation omits the new stamp, creation validation can be bypassed through resolved schema references, and create/replace action behavior was changed in existing v0 implementations rather than through new versioned generations. These issues affect fee estimation, the requiredSince creation invariant, and replay-safe version dispatch, so changes are required before merge.

- [BLOCKING] packages/rs-dpp/src/data_contract/document_type/methods/versioned_methods.rs:422-442: Account for the format-3 stamp in versioned size estimation
Format 3 adds a contract-version varint to every newly serialized document, but PV14 still dispatches `estimated_size` to generation 0, whose model is unchanged from format 2. Drive passes this estimate into stateless GroveDB targets and estimated layer information, while stateful execution serializes the additional one-to-five stamp bytes. This makes the PV14 fee/cost model systematically smaller than the values written by the corresponding execution path. Add a new `estimated_size` generation that includes format 3's added overhead and select it from the PV14 contract-version table, leaving generation 0 unchanged for earlier protocol versions.

- [BLOCKING] packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/data_contract_create/basic_structure/v2/mod.rs:42-62: Resolve property references before enforcing creation-time requiredSince
This loop checks only the literal map of each top-level property. A required property can instead contain `$ref`, with its resolved definition carrying `requiredSince: 2`; `try_from_schema` resolves that reference before applying `requiredSince`, so the parsed `DocumentProperty` receives `Some(2)`, while this validator sees only `$ref` and accepts the version-1 contract. That permits creation-time pre-scheduling despite the invariant this v2 validator is intended to enforce. Validate the already-resolved document properties, or resolve references here through the same resolver used by the parser, and cover a top-level required property backed by `$defs` in a creation test.

- [BLOCKING] packages/rs-drive/src/state_transition_action/batch/batched_transition/document_transition/document_create_transition_action/v0/mod.rs:167-182: Introduce a new action generation instead of changing v0 in place
This changes the existing v0 document-construction implementation to assign the contract-version stamp, while the Drive state-transition table still selects conversion generation 0 for document creation. The same in-place change appears in `document_replace_transition_action/v0/mod.rs`, with replacement also remaining on generation 0. Consensus-critical generations must remain immutable; gating new behavior inside v0 through the DPP serialization slot couples two independently versioned methods and bypasses the Drive dispatch boundary. Move the create and replace stamping behavior into new conversion generations, add the corresponding dispatcher arms, and select those generations only from PV14 while retaining generation 0 for prior protocol versions.
- CI: regenerate withdrawal query test root hashes (every document now carries the stamp byte) and latest-version estimated-fee pins - from_bytes_v3 hard-errors on unconsumed trailing bytes: a reader with a stale contract can no longer silently drop fields a newer-stamped document carries; the error directs it to refetch the contract - requiredSince <= contract version is now enforced on *parsed* document properties (validate_required_since_within_contract_version) at every serialization->struct conversion, closing the $defs $ref bypass of the raw-JSON creation scan; the basic_structure v2 scan remains as an early cheap rejection and is documented as non-authoritative - document types introduced by a contract update (which have no old counterpart for the per-type diff) must annotate requiredSince with exactly the version the update creates - create/replace stamping moved out of the shipped v0 action->Document conversions into new generation-1 modules dispatched on a new document_from_action version slot (DRIVE_STATE_TRANSITION_METHOD_VERSIONS_V4, selected only by protocol v14); v0 restored byte-identical - estimated_size v1 adds the format-3 stamp varint (worst case 5 bytes) to worst-case document size estimation, gated at protocol v14 - CBOR document form carries the stamp as an optional $contractVersion entry (skipped when absent, so pre-stamp CBOR stays byte-identical) - contract_version accessors on Document; regression tests for each fix Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Documents written at protocol v14 carry the contract-version stamp (one stored byte, five in worst-case estimation), which shifts byte-billed processing fees.

Preliminary review — Codex only
One consensus-critical versioning issue remains: PV14-specific data-contract update validation was added directly to the existing generation-0 implementation. The new create/replace action generations are correctly dispatched for PV14, but their stamp behavior still lacks focused regression coverage.

- [BLOCKING] packages/rs-dpp/src/data_contract/methods/validate_update/v0/mod.rs:112-157: Version the contract-level requiredSince update validation
PV14-specific consensus behavior was added directly to `DataContract::validate_update_v0`: it now passes the new contract version into document-type validation and separately rejects invalid `requiredSince` annotations on newly added document types. The outer `DataContract::validate_update` dispatcher still recognizes only generation 0, and `CONTRACT_VERSIONS_V6.methods.validate_update` remains 0. Earlier platform versions currently avoid the new rejection because their parser does not populate `required_since`, but that makes the behavior of an already-shipped generation depend on a separately versioned parser. Preserve `validate_update_v0` unchanged, move the new orchestration into `validate_update_v1`, add the dispatcher arm, and select generation 1 only in the PV14 contract table.
In `packages/rs-drive/src/state_transition_action/batch/batched_transition/document_transition/document_create_transition_action/v1/mod.rs`:
- [SUGGESTION] packages/rs-drive/src/state_transition_action/batch/batched_transition/document_transition/document_create_transition_action/v1/mod.rs:47-68: Cover the new create and replace action generations
The generation-1 create and replace conversions implement the platform-assigned contract-version stamp, but neither module has tests asserting its behavior. The serialization tests manually construct stamped documents and therefore cannot detect a wrong Drive version-table selection, an incorrect fetched contract version, or a missing stamp in one conversion path. Add regression tests showing that PV13/generation 0 leaves `contract_version` unset and PV14/generation 1 assigns the fetched contract version for both borrowed and owned create and replace conversions.

🔴 Blocking: Version the contract-level requiredSince update validation
PV14-specific consensus behavior was added directly to DataContract::validate_update_v0: it now passes the new contract version into document-type validation and separately rejects invalid requiredSince annotations on newly added document types. The outer DataContract::validate_update dispatcher still recognizes only generation 0, and CONTRACT_VERSIONS_V6.methods.validate_update remains 0. Earlier platform versions currently avoid the new rejection because their parser does not populate required_since, but that makes the behavior of an already-shipped generation depend on a separately versioned parser. Preserve validate_update_v0 unchanged, move the new orchestration into validate_update_v1, add the dispatcher arm, and select generation 1 only in the PV14 contract table.

🟡 Suggestion: Cover the new create and replace action generations
The generation-1 create and replace conversions implement the platform-assigned contract-version stamp, but neither module has tests asserting its behavior. The serialization tests manually construct stamped documents and therefore cannot detect a wrong Drive version-table selection, an incorrect fetched contract version, or a missing stamp in one conversion path. Add regression tests showing that PV13/generation 0 leaves contract_version unset and PV14/generation 1 assigns the fetched contract version for both borrowed and owned create and replace conversions.

Issue being fixed or feature implemented
Contract owners cannot add new required fields to an existing document type: the
requiredset is frozen in both directions by the PV14 compatibility rules, for a structural reason — requiredness is baked into the document wire format (required properties serialize raw, optional ones carry a presence flag), so changing it desynchronizes every stored document's bytes from the schema used to read them.This PR makes it possible. A contract update may add a new required property by annotating it with
requiredSinceequal to the contract version the update creates:Documents are stamped with the contract version their bytes conform to (serialization format 3). Deserialization resolves each property's layout by comparing its
requiredSinceagainst the stamp — so the latest contract alone reconstructs every stamp's byte layout. No historical contract lookups are needed anywhere: contract history stays opt-in, and proof verifiers and SDK context providers keep resolving contracts by id at the current version.Design doc with full semantics, invariants, and alternatives considered: https://claude.ai/code/artifact/1c0ea7e4-9029-4f49-861d-ed8d8a79981e
What was done?
requiredSinceproperty keyword admitted by meta-schema v3 (PV14-only, editable per its header comment), parsed ontoDocumentProperty.required_sincebehind a newapply_required_sinceversion slot —Noneon pre-v14 tables so frozen parsers stay byte-identical (therefersTo/apply_property_referencepattern). Parse rules: top-level properties only, must be listed inrequired, value ≥ 1.serialize_v3/from_bytes_v3): a contract-version stamp varint after the format prefix; everything else identical to format 2. A property whoserequiredSinceexceeds the stamp keeps the presence-flagged layout it was written with. NewDOCUMENT_VERSIONS_V4table (default 3) wired intov14.rsonly; read dispatch stays purely prefix-driven, so formats 0–2 deserialize exactly as before.required_at(None): byte-identical for every schema without annotations (i.e. all data that exists on any network), and it keeps old-format bytes readable under a schema that later gained a required field — the key migration path.DocumentV0gainscontract_version: Option<u32>so the stamp rides through read-modify-write. Transfers and purchases re-serialize the fetched document without touching it, so grandfathered documents stay transferable; replace re-supplies full content and re-stamps (lazy migration). Drive assigns the stamp at create/replace beside the other protocol-assigned fields (creator_idprecedent); assignment is gated on format 3 being active so pre-v14 replay builds identical in-memory state.validate_updatev1 strips top-levelrequiredfrom the JSON-schema diff (the same pattern it already uses forindices) and judges it in dedicated name-keyed Rust: additions allowed only for brand-new properties carryingrequiredSince == old version + 1; removals, promotions of existing properties, system fields, and retroactive values rejected with a new consensus errorDataContractInvalidRequiredFieldsUpdateError(code 10276, appended at theBasicErrortail). The compatibility differ gets a frozenrequiredSincerule so tampering with the annotation on an existing property is a clean consensus error rather than an unsupported-keyword hard error (which is chain-halt-shaped).requiredSinceother than 1 via a newbasic_structurev2 for the create transition (v1 shipped at PV13, so it gets a new generation; slot bumped in the PV14 table only) — requiredness changes must arrive with the update that creates the version they name, never pre-scheduled.How Has This Been Tested?
requiredSince; unstamped documents; a format-2 document serialized under the pre-update schema staying readable under the post-update schema; missing-required-at-stamp rejection; layout divergence between stamps.requiredSince; reject retroactive, missing, and mutated annotations; reject promotion of existing properties and removal of required fields.dpp3,990 tests pass,drive(lib) 3,336 pass,json-schema-compatibility-validatorpasses,cargo check --workspace --all-targetsclean, clippy clean on changed crates,cargo fmt --allapplied.Known follow-ups (deliberately not in this PR):
estimated_sizedoes not yet count the stamp bytes (needs a new versioned generation); a drive-abci integration test for the full update → create → transfer grandfathered flow; a unit test for the create-timebasic_structurev2; SDK/WASM surfacing of the stamp; nested-objectrequiredSince; optional→required promotion. Indexing a newly added field remains out of scope (index additions on update are still banned — no backfill).Breaking Changes
Consensus-breaking, gated at protocol v14 (unreleased, v4.2-dev only): new document serialization format 3 with the contract-version stamp, new
requiredSinceschema keyword, relaxed required-set update validation, new consensus error, and the create-transitionbasic_structurev2. Formats 0–2 and all pre-v14 validation behavior are byte-for-byte unchanged for replay.Checklist:
