What this does: A contract can now declare an integer property whose value nobody picks: "generatedFrom": { "function": "sys.random.uniform" } on a property with a minimum and a maximum. When a document is created, the platform writes a placeholder (the minimum). A new Drive step, draw_random_document_properties, then replaces it with a value drawn from the block's random beacon, the BLS threshold signature the block's prevotes combine into. Clients leave the property out and read the drawn value from the proof of their own transition. A replace keeps the drawn value; nobody can send one.
Before, a game had to trust the player (or itself) to pick a card's rarity:
create card { name: "Ace" } -> stored rarity 1 (placeholder)
draw from the block's beacon -> stored rarity 22, index entry moved with it
create card { name: "Ace", rarity: 100 } -> refused: DocumentPropertyNotGeneratedError
replace card { name: "King" } -> rarity stays 22
Value: Games and other fair apps (card rarities, loot, lotteries) get values no sender, proposer or single validator can choose or know in advance, provable with today's proofs and indexable for queries such as "all cards of rarity 90 and up".
Risks:
Consensus: new behaviour is reachable only at protocol version 15, which is unreleased. Protocol version 14 and earlier cannot declare the function: the version 3 meta-schema refuses it and generation 0 of apply_generated_from only takes string transformations.
Release dependency: this PR writes the placeholder and provides the draw, but nothing calls the draw yet. The beacon reaches Drive through a new Tenderdash ABCI method, ApplyBlockRandomness, in follow-up PRs (Tenderdash, rs-tenderdash-abci, and the Drive wiring that activates it). 5.1 must not ship with this PR and without those, or documents would keep their placeholders.
Compiled contract storage: the stored generatedFrom gains a range field, so the encoding of protocol version 15 compiled contracts changes. Version 15 is unreleased; devnets are reset each release.
Platform has no native randomness, so games either trust a party to pick values or build commit-reveal schemes on top. The design behind this PR uses randomness validators already produce: when 2/3 of the quorum prevote for a block, their BLS shares combine into exactly one threshold signature that nobody can compute in advance. Tenderdash will hand that signature to Drive between the prevotes and the precommits, Drive fills the random values, and the precommits sign the state with the values in it. So the value is final, and provable, when the block that asked for it commits.
This differs from #4682's request-then-later-lookup model: there is no "not ready" state, because the value is fixed when its own block commits. A coalition able to withhold the polka (the online quorum members minus 66 of a 100-member quorum) can force another round and with it another draw; that exposure is accepted.
What was done?
dpp
SystemFunction::Random(RandomFunction::Uniform), wire name sys.random.uniform, in a new sys.random namespace (property/generated_from/system_function/random.rs). It takes no parameters and generates an integer.
SystemFunction::platform_generated(): true for the token functions (read from state) and the random ones (drawn). The places that mean "only the platform writes this value, a client leaves it out" now use it instead of reads_state(): adopt_state_generated_properties (proof verification), validate_generated_from_properties, state_generated_paths_left_out and the client stand-ins.
GeneratedFrom::range: Option<RandomRange>, the property's minimum and maximum read at registration, also in the stored form of compiled contracts (StoredGeneratedFrom.range, StoredSystemFunction::Random).
apply_generated_from v1 (protocol version 15) parses the function: an integer property of at most 64 bits, both bounds declared and inside the type, minimum <= maximum, no enum, const, exclusiveMinimum, exclusiveMaximum or multipleOf. params may be left out. The native schema check admits it.
validate_generated_from_declarations: ordinary and compound indexes are allowed; unique (and so contested) indexes are refused, since two draws could collide after nothing can be refused any more; refused on indexOnly types and on types that keep history; declared in place like a token-generated property.
DocumentTypeBasicMethods::generate_random_properties: a create writes the placeholder and refuses a sent value; a replace keeps the stored value and refuses another.
drive
The document create and replace transformers call generate_random_properties beside the token decimals.
Drive::draw_random_document_properties (new, draw_random_document_properties: Some(0) in DRIVE_DOCUMENT_METHOD_VERSIONS_V5, None before): for each document a block created, draws its random properties and rewrites it in place, moving each index entry the value changes. Unbilled: the creation paid for the placeholder, which takes the same storage. Skips a document a later transition deleted and a type that draws nothing.
The draw: SHA-256 of a domain, the beacon, and the document property it is for (contract, type, document id, path; each variable part length-prefixed); the first 16 bytes, big-endian, modulo the range's size, offset the minimum. Ranges hold at most 2^64 values, so no value is favoured by more than 2^-64. Two test vectors pin it.
The rewrite reuses the document update path: update_document_for_contract_operations v1's body is split out unchanged as update_stored_document_operations_v1, past the refusal of immutable types, so draws also work on immutable types (typical for game items).
The create/replace subscription filter refuses a clause on a random property as it does on a token-generated one.
How Has This Been Tested?
New tests:
rs-dpp/.../try_from_schema/v3/generated_from_random_tests.rs: parses sys.random.uniform at protocol version 15 (with and without params, signed ranges) and refuses it at 14; refuses a missing or inverted bound, enum, multipleOf, exclusiveMaximum, a string property and a parameter; admits an ordinary index and refuses a unique one; refuses indexOnly and history-keeping types; the create placeholder and the refusal of a sent value; a replace keeping the stored value; a client leaving the value out; proof-time adoption.
rs-dpp/.../system_function/random.rs: range size and offsets up to 2^64 values; storing a value at the property's width.
rs-drive/src/drive/document/draw_random_document_properties/v0: a draw into a document of an immutable type moves its byRarity index entry (a query by the drawn value finds it, by the placeholder does not); draws differ by document, beacon and property and repeat exactly; two pinned vectors; deleted documents and types without random properties are skipped; the method is not active before protocol version 15.
rs-drive-abci/.../batch/tests/document/generated_from_random.rs, through process_raw_state_transitions: a create writes the placeholder, the draw replaces it, and the client's proof verification of its own create returns the drawn value; a create sending a value is refused (paid); a replace keeps the drawn value and refuses another.
Consensus, at protocol version 15 only (unreleased): contracts may declare sys.random.uniform, creates write its placeholder and refuse a sent value, replaces keep the stored value. The encoding of protocol version 15 compiled contracts gains the range field.
In-place changes to shipped generations
update_document_for_contract_operations v1 (selected by protocol versions 14 and 15): the body after the refusal of immutable types moved, unchanged, into update_stored_document_operations_v1. The refusal now runs before without_storage_flags_if_expiring, which it does not depend on: it reads only the document type, which that call leaves as it is. Identical operations at every version.
validate_generated_from_properties v0, adopt_state_generated_properties, the client stand-ins and the subscription filter (all reachable at protocol version 14): reads_state() became platform_generated(). Inert at 14 and earlier, since no type parsed there can declare a random function (generation 0 of apply_generated_from takes string transformations only, and the version 3 meta-schema lists only those).
add_indices_for_top_index_level_for_contract_operations v2 (selected by protocol versions 14 and 15): its condition for storage flags on index trees moved, unchanged, into DocumentAndContractInfo::index_trees_carry_storage_flags. update_stored_document_operations_v1 gains index_trees_as_inserted, which a document update passes as false, so it writes what it did.
Drive document method tables v1 to v4 gain draw_random_document_properties: None, a new slot nothing at those versions reads.
apply_generated_from v1, the native schema check and the stored contract format were introduced for protocol version 15, which is unreleased, so they are amended in place.

Summary by CodeRabbit
New Features
Added support for integer properties drawn uniformly from an inclusive range using a block’s random beacon. New documents use a placeholder until the draw; replacements preserve stored values, and relevant indexes are updated with required fees prepaid.
Bug Fixes
Strengthened validation for references, indexes, and constraints involving randomly drawn properties to prevent invalid declarations and lookups based on placeholder values.
Documentation
Documented range requirements and client handling. Protocol version 15 can parse the feature, but registration remains unavailable until it is activated.
A contract can declare an integer property drawn from the block's random
beacon: `"generatedFrom": { "function": "sys.random.uniform" }` on a property
with a minimum and a maximum (protocol version 15). A create writes the
placeholder (the minimum) and refuses a sent value; a replace keeps the stored
value; clients leave it out and take it from the proof.
- dpp: the `sys.random` namespace, `SystemFunction::platform_generated`, the
range on `GeneratedFrom` (and its stored form), parsing and registration
checks (ordinary indexes allowed, unique ones refused, not on indexOnly or
history-keeping types), and `generate_random_properties`.
- drive: the create and replace transformers write and keep the value, and
`Drive::draw_random_document_properties` draws each value from the beacon
and rewrites the document in place, index entries included, reusing the
update path's body split out of `update_document_for_contract_operations`
v1 unchanged.
Nothing calls the draw yet: the beacon arrives through Tenderdash's
ApplyBlockRandomness ABCI method in follow-ups.

It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
The change adds sys.random.uniform for bounded integer document properties. It adds registration checks, create-time placeholders, replacement handling, and Drive methods that draw values from a block beacon and update indexes. Protocol version 15 configures drawing, while registration remains inactive.
The generated-from model and stored form support random ranges. The parser accepts sys.random.uniform without parameters and validates integer property bounds. The version tables leave registration inactive and configure the protocol-15 draw method. Documentation and the changelog describe the declaration and API changes.
Registration and read restrictions packages/rs-dpp/src/data_contract/document_type/class_methods/try_from_schema/*, packages/rs-dpp/src/data_contract/document_type/class_methods/try_from_schema/common/mod.rs, packages/rs-dpp/src/data_contract/document_type/property/*, packages/rs-drive-abci/src/execution/validation/.../data_contract_reference_validation/v0/mod.rs
Registration rejects random-generated properties in specified index, reference, encryption, aggregation, and rule-read cases. Reference-read tracking preserves full property paths. Tests cover registration and derived-index restrictions.
Create processing inserts the range minimum as a placeholder and refuses client-supplied values. Replace processing preserves the stored value or refuses a different supplied value. Create processing prepays when an index contains a random property. Create-cost estimates refuse document types with such indexed properties.
Beacon draw and index updates packages/rs-drive/src/drive/document/draw_random_document_properties/*, packages/rs-drive/src/drive/document/mod.rs, packages/rs-dpp/src/data_contract/document_type/mod.rs, packages/rs-platform-version/src/version/drive_versions/drive_document_method_versions/*
Drive draws values from the beacon and updates stored documents and indexes. The implementation includes index-entry prepayment and handles TTL costs. The version tables configure drawing for protocol version 15.

Final validation — Phase 1 + Phase 2
At head 58abc9a, five blocking issues remain: registration is active without production draws, and the late rewrite does not preserve storage accounting, aggregate safety, dependent indexes, or property constraints. The inspected protocol-version isolation is sound; four non-blocking documentation, API-hardening, and test improvements are also retained. This was a static review: current CI still has Rust workspace setup, JavaScript builds, and Kotlin checks pending; the two newer base commits concern CI and do not conflict with the reviewed files.

🟡 Suggestion: Document sys.random.uniform in the contract keyword reference book/src/contract-keywords/generated-from.md:1-15

The contract-keywords.md function table also omits it. Document the optional empty parameters, required integer bounds, declaration restrictions, placeholder/finalization lifecycle, and replace behavior so contract authors can use the new grammar without relying on the PR description.

In `packages/rs-dpp/src/data_contract/document_type/class_methods/try_from_schema/mod.rs`:
- [BLOCKING] packages/rs-dpp/src/data_contract/document_type/class_methods/try_from_schema/mod.rs:3220-3222: Keep random-property registration disabled until production draws are wired
Protocol version 15 now accepts sys.random.uniform, and the create transformer stores its minimum as a placeholder. However, every invocation of draw_random_document_properties outside its implementation is in a test; production Drive-ABCI neither collects the requests nor invokes the draw. A successfully committed create therefore retains the predictable minimum indefinitely at this revision. The pinned rs-tenderdash-abci also has no ApplyBlockRandomness interface. The release dependency disclosed in the description and the upstream transport work in dashpay/tenderdash#1582 do not make the enabled registration path fail closed. Keep registration disabled until the full consensus integration is present, or include that integration before enabling declarations.
- [BLOCKING] packages/rs-dpp/src/data_contract/document_type/class_methods/try_from_schema/mod.rs:3545-3558: Exclude random-dependent sums that can overflow during the late draw
The admission checks reject unique indexes but still allow the random property to be documentsSummable or an index's summable/averageable contribution. A required signed integer with range [-1, i64::MAX] is accepted as a sum source. Multiple creates initially contribute only -1 each, while their individually valid draws can produce a total exceeding i64::MAX. The rewrite recomputes ItemWithSumItem and ReferenceWithSumItem contributions through update_stored_document_operations_v1. In the pinned GroveDB, Merk's aggregate_data uses checked i64 addition and returns Overflow, which propagates out of the draw. This defeats the requirement that the intended post-acceptance step cannot reject an accepted block. Add registration-time restrictions or an aggregation design that guarantees every admitted draw is representable, with coverage for aggregate overflow rather than only individual range bounds.
- [BLOCKING] packages/rs-dpp/src/data_contract/document_type/class_methods/try_from_schema/mod.rs:3559-3567: Reject property constraints that can be invalidated by the late draw
These checks restrict JSON Schema but leave propertyConstraints free to inspect the random value. For example, rarity in [1, 100] can declare propertyConstraints: {"onlyOne":{"equal":["rarity",1]}}. Creation inserts the placeholder 1, and validate_property_constraints_v0 evaluates the rule against it because consensus has no unknown-value exclusion. The draw later writes a different value directly through the storage updater without evaluating the rule, leaving a successfully created document in violation of its contract. A rule requiring rarity above the minimum instead makes every create fail before a draw is possible. Referencing constraints can likewise make decisions from the temporary value. Extend DPP's registration/read validation to reject unsafe readers of pending random values, or supply semantics that guarantee those rules remain valid after finalization.
In `packages/rs-drive/src/drive/document/draw_random_document_properties/v0/mod.rs`:
- [BLOCKING] packages/rs-drive/src/drive/document/draw_random_document_properties/v0/mod.rs:172-178: Account for draw-created index storage and its refund obligations
Equal-width integers do not imply equal index storage. Several creates initially share the minimum-value branch and its non-unique reference bucket, paying for those shared trees once. Distinct draws then create additional value branches and buckets. The update helper passes the document's refundable StorageFlags into those insertions, but this temporary accumulator discards their storage and processing costs along with the old branch's removal accounting. Normal later deletion converts the new flagged elements' removed bytes into refunds, creating refund liabilities for storage that was never funded. The draw also repeats state reads and index rewrites without charging their processing work. Route the draw through the cost/FeeResult pipeline, reserve or precharge its worst-case work during creation, and reconcile the actual storage/removal delta. An intentional processing subsidy would not resolve the unfunded storage obligations.
- [BLOCKING] packages/rs-drive/src/drive/document/draw_random_document_properties/v0/mod.rs:156-171: Preserve the fixed-value invariant used by dependent derived indexes
The draw repairs only the drawn document's own indexes, but other documents can already be indexed by its placeholder. An immutable, non-deletable card with random rarity passes schema_property_is_fixed_once_written, because that helper checks mutability and moderator flags without excluding delayed random generation. A reply type can consequently reference the card through permanentDocument and index cardId.rarity. Creating the card and then the reply in separate transitions of the same block indexes the reply under the minimum. Drawing the card changes rarity without moving the reply's entry; queries then miss it, and subsequent maintenance reconstructs a different path from the final referenced value. Reject pending-random fields as derived-index sources in the owning DPP admission rules, or prevent dependent entries from materializing until their source is final. Add a same-block source-and-dependent regression test.

- [SUGGESTION] packages/rs-drive-abci/src/execution/validation/state_transition/state_transitions/batch/tests/document/generated_from_random.rs:368-372: Assert that the verified proof contains the created document
VerifiedDocuments contains a map of Identifier to Option<Document>. values().flatten() discards absence entries, and all() succeeds on an empty iterator. This assertion therefore also accepts an empty map or an absence-only result, rather than establishing that the client received the created document with its drawn value. Assert the expected ID, a Some document, and the expected result count explicitly.
In `packages/rs-platform-version/src/version/drive_versions/drive_document_method_versions/v5.rs`:
- [SUGGESTION] packages/rs-platform-version/src/version/drive_versions/drive_document_method_versions/v5.rs:28: Record the randomness feature in the protocol 15 changelog
The activation slot is present, but version/v15.rs still ends its numbered changelog at item 17 and describes apply_generated_from generation 1 as admitting sys.tokens.decimals without mentioning randomness. CONTRACT_VERSIONS_V7 has the same omission. The Platform Version chapter explicitly requires each consensus change to appear in the snapshot's doc-comment changelog. Add the random-property grammar, create/replace semantics, compiled-contract payload change, and production-wiring prerequisite, and update the corresponding drive/DPP annotations. The activation tables themselves do not require another version bump.
In `book/src/contract-keywords/generated-from.md`:
- [SUGGESTION] book/src/contract-keywords/generated-from.md:1-15: Document sys.random.uniform in the contract keyword reference
The public reference still describes integer generation only through sys.tokens.decimals, shows params as mandatory, and omits sys.random.uniform from the Where/Since rows and function documentation. The contract-keywords.md function table also omits it. Document the optional empty parameters, required integer bounds, declaration restrictions, placeholder/finalization lifecycle, and replace behavior so contract authors can use the new grammar without relying on the PR description.

- [SUGGESTION] packages/rs-dpp/src/data_contract/document_type/property/generated_from/system_function/random.rs:56-58: Enforce RandomRange invariants at its public construction boundary
Registration protects ordinary contracts, but RandomRange exposes unrestricted public i128 fields and derives Deserialize; the compiled-contract conversion also reconstructs it without checking its bounds. Safe callers can construct an inverted range whose size() reports a positive cardinality, or [i128::MIN, i128::MAX], for which abs_diff + 1 overflows. The latter panics with overflow checks or wraps to zero, which would make draw_v0's modulo panic if such a range reached it. Make construction and deserialization checked, or make cardinality explicitly fallible, while preserving behavior for admitted ranges of at most 2^64 values. Saturating the addition alone would avoid one panic but would not restore the abstraction's range/cardinality invariant.
Your move: thepastaclaw requested changes on this head; dismiss the review or push a fix; thepastaclaw left review threads unresolved; resolve them.

…index entries, refuse unsafe readers
Review follow-ups:
- `random_generated_from` (new, None in every table, protocol version 15
included) keeps `apply_generated_from` 1 refusing `sys.random.uniform`
until the release that wires the draw in turns it on; the end-to-end tests
move with that release.
- A create whose type indexes a random property prepays Drive's estimated
(average-layer) cost of the index entries the draw may create, through
`Drive::prepay_random_document_index_entries`, so later refunds of those
entries are funded. The draw stays unbilled.
- Registration refuses a random property as a sum or average source, as a
derived-index source, read by any contract rule (propertyConstraints,
deleteConstraints, immutable when, retractedWhen, referenced reads,
reference where/findBy reads, countOf/sumOf filter keys), and on a type
with a contested index.
- `RandomRange` is checked at construction and decoding.
- Changelog note 18 in protocol version 15 and the generatedFrom chapter.

Pin the indexed prepayment fee to an exact FeeResult.
The should_prepay_the_draw_of_an_indexed_random_property_on_create test in transformer.rs checks only that the indexed fee is greater than the unindexed fee for storage and for processing. The unindexed looseCard fee is FeeResult::default(), and should_prepay_nothing_for_a_random_property_in_no_index asserts that value. Any small positive fee therefore passes. The indexed prepayment in should_prepay_the_entries_of_the_indexes_holding_a_random_property_only in draw_random_document_properties/v0/mod.rs has the same gap. It asserts only that storage_fee and processing_fee are greater than zero.
Assert the exact FeeResult for the estimated index entries in both tests. Keep the existing default-fee assertions for the unindexed cases. A change to the index-entry fee estimate would then fail the tests.

Re-review — Final validation — Phase 1 + Phase 2
Verified the supplied findings against head 70eff44: six prior findings are fixed, one is outdated, and two remain as non-blocking pre-activation concerns; the new prepayment path also mishandles unresolved derived index values. Registration correctly fails closed in every production protocol version, but current Rust workspace CI has now failed two latest-version root characterizations affected by the compiled-contract encoding change. This was a static review only; the supplied base-drift evidence reports no conflicts or overlapping changes.

This calls the index walker without the with_derived_index_values preparation used by normal insertion. The create transformer invokes prepayment immediately after constructing an action with derived_index_values: None; reference validation supplies those values only later. A permitted compound index combining local random rarity with a fixed referenced field such as cardId.name is retained by with_only_indexes, but its concrete document lacks the synthetic cardId.name value. get_raw_for_document_type_v0 explicitly returns CorruptedCodeExecution for that unresolved derived property, so creation fails before reaching normal insertion.

- [SUGGESTION] packages/rs-drive/src/drive/document/draw_random_document_properties/v0/mod.rs:87-94: Account for draw-created index storage and its refund obligations
(existing thread: https://github.com/dashpay/platform/pull/5749#discussion_r4459517547)
The new prepayment charges ordinary fixed-fan-out entries, but DocumentRefInfo makes the walker price the concrete placeholder's footprint rather than every footprint the draw can create. For a random U16 rarity in [0, 1000], integerRange: {"on":"rarity","range":100,"step":10} gives placeholder 0 only the clamped window at 0. Both creation and prepayment therefore price one window, whereas a draw of 100 occupies ten windows, with starts 100 through 10. bucket_index_keys takes its concrete-key branch here; estimated layer information changes pricing but does not substitute maximum fan-out. The draw creates the additional refundable elements and still discards their storage costs. The same reservation assumption also misses an initially skipped compound index populated by a same-block replace before drawing. Reserve a sufficient final footprint, maintain the reserve across updates, or restrict unsupported combinations, and cover these lifecycle cases in the fee tests. This concerns storage funding, not the documented processing subsidy; current registration gating contains production exposure.

(existing thread: https://github.com/dashpay/platform/pull/5749#discussion_r4459517553)
The contribution check closes the original random-summand example, but it still permits a random grouping key for an index summing another property. For example, random rarity in [1, 2] can key a non-unique index with summable: "amount", where required signed amount admits [-1, i64::MAX], without documentsSummable or rangeSummable. An existing drawn document can contribute i64::MAX in rarity bucket 2, while a new amount-1 document fits separately under placeholder bucket 1. Drawing the new document to 2 moves its ReferenceWithSumItem into the full SumTree. The pinned GroveDB implementation performs checked i64 aggregate addition and returns Overflow, which propagates from the post-acceptance draw. Reject random-dependent sum/average grouping unless redistribution is guaranteed representable, and add an existing-destination-bucket regression. This remains in scope as an incomplete draw invariant, but the closed registration gate makes it a pre-activation suggestion rather than a currently reachable chain blocker.

Full checklist in the description.
…lues before the random prepay
- The stored random range moves into the stored Random function variant, so
every declaration of another function compiles to the bytes it did before
(the latest-version root pins hold again); a byte pin test guards it.
- The create's random-index prepayment completes the document's derived
index values, estimated, as the insert does, instead of keying an entry on
a value the create's document does not carry yet.
- Registration refuses index shapes the prepayment cannot cover: an index
holding a random property that sums or averages another property, an
integerRange index on it, and on a mutable type an index skipping
documents on a stored property a same-block replace could add.

Pin the derived-index prepayment fee in the setCard test.
The test at transformer.rs:479-489 asserts only that storage_fee and processing_fee are greater than zero. Those assertions still pass if the estimate for the byRarityAndSetName entry shrinks or changes. Pin the exact FeeResult as the neighboring should_prepay_the_draw_of_an_indexed_random_property_on_create test does. Add a case that creates the referenced set and compares the estimate with the real setId.name key.

prepay_random_document_index_entries_v0 constructs this projection for each random-indexed insertion, including concrete create estimates. to_owned_document_type deep-clones the owned schema, property maps, constraints, indexes, and original index structure before keep_only_indexes filters the indexes and rebuilds that structure.

Each random-indexed insertion calls this projection through prepay_random_document_index_entries_v0. DocumentTypeV2's derived Clone copies the owned schema, both property maps, constraints and complete index structure before keep_only_indexes filters the indexes and rebuilds their structure. The contract-size limit bounds one copy, but repeated creates of the same type—and concrete insertion estimates—repeat allocations proportional to unrelated schema content. Registration being disabled makes this nonblocking, and avoiding a wider shared-walker change here is reasonable. Use a borrowed index filter or a projection cached by contract revision and document type; if retaining this implementation, link a tracking issue or follow-up PR for the pre-activation optimization rather than leaving it only in the discussion.

The reservation calls with_only_indexes(), which deep-clones the document type before retaining selected indexes and rebuilding its index structure.

Concrete create estimates also reach this reservation, so estimation and application can repeat the same metadata allocation across documents of one type.

with_only_indexes deep-clones the entire document type before filtering its indexes. DocumentTypeV2's derived Clone copies the owned schema, nested and flattened property maps, constraints, and original index structure; keep_only_indexes then replaces that structure. The insertion path repeats this work for concrete create estimates as well as applied creates, so pricing a small random-bearing index repeatedly copies unrelated metadata from the same type. The contract-size limit bounds each copy but does not amortize repeated calls. A borrowed index projection or a non-persisted Drive-side projection cache keyed by contract revision, document type, and relevant platform version would avoid that work while keeping pricing in Drive. Registration is inactive, so a wider projection change need not block this PR, but the proposed before-activation follow-up needs a linked issue or follow-up PR before it can be treated as tracked deferral.

Fixed in d4ccbc9: the draw now writes index trees with the flags an insert gives them, through a shared DocumentAndContractInfo::index_trees_carry_storage_flags, and references keep the document's flags as an insert's do; should_leave_the_index_elements_an_insert_of_the_drawn_value_writes checks that the state root and the delete fee match a direct insert for immutable and mutable types.

The new regression compares state roots and deletion fees against direct insertion for immutable, compound-indexed, and mutable types.
An immutable type of a contract that cannot be deleted keeps no storage flags
on its index trees, and its references keep the document's. A draw wrote the
flags on the trees it created, which the create had not prepaid. The rule moves
unchanged from add_indices_for_top_index_level_for_contract_operations v2 to
DocumentAndContractInfo::index_trees_carry_storage_flags, and the draw follows
it. Document updates pass false and write what they did.

Re-review — Final validation — Phase 1 + Phase 2
Verified the complete diff at d4ccbc9 and revalidated all 22 prior findings. The shared index-flags policy resolves the latest correctness issue, registration remains fail-closed, and one nonblocking performance suggestion remains untracked. This was a static review: current CI passes Rust workspace tests, wasm32 tests, the JS build, and mobile checks; Dashmate and Evo SDK JavaScript suites remain pending, with no failed code checks reported.

Triage: critical by gpt-6.1-sol (effort low) — The large, intricate diff changes consensus-visible document generation and indexed state mutation in draw_random_document_properties/v0 and document_create_transition_action/v0/transformer.rs, alongside protocol-15 activation and persisted contract encoding.
These findings are from an automated code review. Verify each finding against the current code and only fix it if needed.

- [SUGGESTION] packages/rs-dpp/src/data_contract/document_type/mod.rs:467-473: Avoid cloning the entire document type for each reservation
(existing thread: https://github.com/dashpay/platform/pull/5749#discussion_r4462749114)
Each random-indexed insertion reaches prepay_random_document_index_entries_v0, which calls this projection. to_owned_document_type deep-clones the owned schema, property maps, constraints, indexes, and existing index structure; keep_only_indexes then filters the indexes and builds another structure. Reservation preparation therefore scales with the whole type definition per insertion, even when only one small index needs pricing. The contract-size limit bounds each clone but does not remove repetition across documents or estimation and execution. Keeping a shared-walker refactor outside this inactive groundwork is reasonable. A Drive-owned projection cache keyed by contract revision, document type, and selected protocol version could preserve the parsed type and walker interfaces; a borrowed index filter is another option. If deferred until activation, link a concrete tracking issue or follow-up PR rather than leaving the optimization only in this thread.

Basic explanation
What this does: A contract can now declare an integer property whose value nobody picks:
"generatedFrom": { "function": "sys.random.uniform" }on a property with aminimumand amaximum. When a document is created, the platform writes a placeholder (theminimum). A new Drive step,draw_random_document_properties, then replaces it with a value drawn from the block's random beacon, the BLS threshold signature the block's prevotes combine into. Clients leave the property out and read the drawn value from the proof of their own transition. A replace keeps the drawn value; nobody can send one.Before, a game had to trust the player (or itself) to pick a card's rarity:
After:
Value: Games and other fair apps (card rarities, loot, lotteries) get values no sender, proposer or single validator can choose or know in advance, provable with today's proofs and indexable for queries such as "all cards of rarity 90 and up".
Risks:
apply_generated_fromonly takes string transformations.ApplyBlockRandomness, in follow-up PRs (Tenderdash, rs-tenderdash-abci, and the Drive wiring that activates it). 5.1 must not ship with this PR and without those, or documents would keep their placeholders.generatedFromgains arangefield, so the encoding of protocol version 15 compiled contracts changes. Version 15 is unreleased; devnets are reset each release.Issue being fixed or feature implemented
Refs #4682.
Platform has no native randomness, so games either trust a party to pick values or build commit-reveal schemes on top. The design behind this PR uses randomness validators already produce: when 2/3 of the quorum prevote for a block, their BLS shares combine into exactly one threshold signature that nobody can compute in advance. Tenderdash will hand that signature to Drive between the prevotes and the precommits, Drive fills the random values, and the precommits sign the state with the values in it. So the value is final, and provable, when the block that asked for it commits.
This differs from #4682's request-then-later-lookup model: there is no "not ready" state, because the value is fixed when its own block commits. A coalition able to withhold the polka (the online quorum members minus 66 of a 100-member quorum) can force another round and with it another draw; that exposure is accepted.

It takes no parameters and generates an integer.SystemFunction::platform_generated(): true for the token functions (read from state) and the random ones (drawn). The places that mean "only the platform writes this value, a client leaves it out" now use it instead ofreads_state():adopt_state_generated_properties(proof verification),validate_generated_from_properties,state_generated_paths_left_outand the client stand-ins.GeneratedFrom::range: Option<RandomRange>, the property'sminimumandmaximumread at registration, also in the stored form of compiled contracts (StoredGeneratedFrom.range,StoredSystemFunction::Random).apply_generated_fromv1 (protocol version 15) parses the function: an integer property of at most 64 bits, both bounds declared and inside the type,minimum <= maximum, noenum,const,exclusiveMinimum,exclusiveMaximumormultipleOf.paramsmay be left out. The native schema check admits it.validate_generated_from_declarations: ordinary and compound indexes are allowed; unique (and so contested) indexes are refused, since two draws could collide after nothing can be refused any more; refused onindexOnlytypes and on types that keep history; declared in place like a token-generated property.DocumentTypeBasicMethods::generate_random_properties: a create writes the placeholder and refuses a sent value; a replace keeps the stored value and refuses another.drive
generate_random_propertiesbeside the token decimals.Drive::draw_random_document_properties(new,draw_random_document_properties: Some(0)inDRIVE_DOCUMENT_METHOD_VERSIONS_V5,Nonebefore): for each document a block created, draws its random properties and rewrites it in place, moving each index entry the value changes. Unbilled: the creation paid for the placeholder, which takes the same storage. Skips a document a later transition deleted and a type that draws nothing.update_document_for_contract_operationsv1's body is split out unchanged asupdate_stored_document_operations_v1, past the refusal of immutable types, so draws also work on immutable types (typical for game items).How Has This Been Tested?
New tests:

Consensus, at protocol version 15 only (unreleased): contracts may declare
sys.random.uniform, creates write its placeholder and refuse a sent value, replaces keep the stored value. The encoding of protocol version 15 compiled contracts gains therangefield.In-place changes to shipped generations
update_document_for_contract_operationsv1 (selected by protocol versions 14 and 15): the body after the refusal of immutable types moved, unchanged, intoupdate_stored_document_operations_v1. The refusal now runs beforewithout_storage_flags_if_expiring, which it does not depend on: it reads only the document type, which that call leaves as it is. Identical operations at every version.validate_generated_from_propertiesv0,adopt_state_generated_properties, the client stand-ins and the subscription filter (all reachable at protocol version 14):reads_state()becameplatform_generated(). Inert at 14 and earlier, since no type parsed there can declare a random function (generation 0 ofapply_generated_fromtakes string transformations only, and the version 3 meta-schema lists only those).add_indices_for_top_index_level_for_contract_operationsv2 (selected by protocol versions 14 and 15): its condition for storage flags on index trees moved, unchanged, intoDocumentAndContractInfo::index_trees_carry_storage_flags.update_stored_document_operations_v1gainsindex_trees_as_inserted, which a document update passes asfalse, so it writes what it did.draw_random_document_properties: None, a new slot nothing at those versions reads.apply_generated_fromv1, the native schema check and the stored contract format were introduced for protocol version 15, which is unreleased, so they are amended in place.Checklist:
