feat(dpp): unify JSON/Value conversion traits + comprehensive round-trip tests

[shumkov]

Summary

Unification of JSON/Value conversion across rs-dpp + wasm-dpp2: canonical JsonConvertible / ValueConvertible traits on every domain type, ~80 trait impls + ~200 round-trip tests, and a coordinated deprecation sweep that removed all 5 documented Critical bugs and most legacy non-canonical conversion mechanisms.

What landed (high-level)

• Pass 1: canonical JsonConvertible / ValueConvertible impls on ~80 rs-dpp domain types.
• Pass 2: ~200 dedicated json_convertible_tests / value_convertible_tests modules with full wire-shape assertions per type.
• Phase D (steps 1–11): deprecation and deletion of non-canonical conversion mechanisms. Removed StateTransitionValueConvert/StateTransitionJsonConvert traits + 68 impl files, A6/A7/A8/A9 identity traits, A10/A11 document traits down to one helper each, AssetLockProof asymmetric methods, and the _versioned DataContract method family. Replaced with canonical + (for DataContract) from_*_validated(value, &pv) opt-in validation.
• All 5 Critical findings resolved (see table below).
• Upstream PRs landed — dashcore fix: Starcounter-Jack JSON-Patch Prototype Pollution vulnerability #708 + feat(drive): log number of refunded epochs #729 merged; this branch dropped the local outpoint_serde wrapper. The blstrs_plus PR is still pending (one ValidatorSet value-round-trip test remains #[ignore]).

Critical findings status

#	Finding	Resolution
Critical-1	is_human_readable HR/non-HR divergence	Documented on both canonical traits in serialization_traits.rs with the divergence table + ContentDeserializer caveat + pointer to canonical dual-shape visitor examples.
Critical-2	Silent array→bytes coercion in From<JsonValue> for Value	Heuristic removed (rs-platform-value/src/converter/serde_json.rs). Faithful conversion: JSON array → Value::Array. Pin tests added.
Critical-3	ExtendedDocument non-round-trippable	Replaced broken manual serde with #[serde(tag = "$extendedFormatVersion")] derive; round-trip tests added.
Critical-4	DataContract serde impurity	Platform-version coupling pinned in 3 regression tests; validation flipped to opt-in (Deserialize no longer hardcodes full_validation=true); KEEP-AS-EXCEPTION rationale documented at all 3 sites.
Critical-5	to_canonical_object sorts keys (assumed signature-load-bearing)	Falsified — signing uses bincode (PlatformSignable derive). Methods had zero production callers; deleted along with A1/A2.

DataContract API — final shape

The deprecation sweep collapsed the _versioned method family into a clear split by validation policy:

• No validation (the new default): canonical serde_json::from_value::<DataContract>(json) / platform_value::from_value::<DataContract>(v) / serde_json::to_value(&dc) / platform_value::to_value(&dc). Use for storage reads, internal round-trips.
• Opt-in validation: DataContract::from_json_validated(json, &pv) / from_value_validated(value, &pv). Use on trust boundaries (SDK ingest, fixture loaders). No bool param — name implies always-validates.
• Kept: to_validating_json(&pv) — different concept (produces JSON-Schema-compatible output with binary as u8 arrays).
• Deleted entirely: to_*_versioned, into_value_versioned, from_*_versioned(_, full_validation, _).

Test results

• rs-dpp: 3619/3619 lib tests pass, 0 failed, 7 ignored. Of the 7 ignored: 6 are pre-existing recursive_schema_validator ignores; 1 is ValidatorSet::value_round_trip_with_full_wire_shape (pending blstrs_plus upstream PR).
• rs-platform-value: 1036/1036 lib tests pass.
• rs-drive: 3040/3040 lib tests pass.
• rs-sdk: 117/117 lib tests pass.
• rs-sdk-ffi: 252/252 lib tests pass.
• Workspace cargo check --tests clean across dpp / drive / drive-abci / wasm-dpp / wasm-dpp2 / dash-sdk / rs-sdk-ffi.

Architectural conventions established

• Tag-shape rules: all versioned outer enums use #[serde(tag = "$formatVersion")]; all discriminated enums use a $-prefixed key ($type, $action, $transition); zero adjacent-tagged enums remain.
• #[json_safe_fields] rollout: 25+ V0/V1 struct leaves carry the attribute. JS-safe large-integer protection at every serialization site.
• Wire-shape test convention: json!{} / platform_value!{} literal assertions in every round-trip test (~85 tests on this convention).
• Wasm-side adapter pattern: impl_wasm_conversions_inner! (45 sites in wasm-dpp2) for rs-dpp domain types using canonical traits; impl_wasm_conversions_serde! (20 sites) for wasm-only DTOs without rs-dpp counterparts — pattern documented and re-audited.

Cross-package audit (just before shipping)

• wasm-sdk: 0 manual Serialize/Deserialize, 0 references to deleted legacy APIs, 38 impl_wasm_serde_conversions! applications. All DTOs follow canonical patterns.
• wasm-dpp2: 3 manual serde impls (IdentifierWasm, PoolingWasm, PlatformAddressWasm) — all documented production-required adapters for lenient JS-facing parsing; rest of crate flows through canonical helpers.
• rs-sdk / rs-sdk-ffi / swift-sdk: no breakage; no references to deleted APIs.

Out of scope (separate work)

• blstrs_plus BLS PublicKey dual-shape deserialize — pending upstream. One ValidatorSet value-round-trip test remains #[ignore] until it lands.
• Pass 5 (delete the legacy wasm-dpp crate) — blocked on team decision.

Docs

• docs/json-value-unification-plan.md — the live plan + status doc (regularly updated through the work).
• docs/json-value-conversion-inventory.md — pre-pass-1 structural inventory.
• docs/json-value-conversion-canonical-pattern.md — the canonical-trait usage pattern, kept up to date.

Test plan

• CI green (currently 3 success / 12 skipped / 0 failed).
• Reviewer runs cargo test -p dpp --features all_features_without_client --lib and sees 3619 pass / 0 fail.
• Reviewer skims docs/json-value-unification-plan.md to confirm the architectural decisions (validation-opt-in, KEEP-AS-EXCEPTION for DataContract, tag-shape conventions) match team intent.
• Spot-check a wasm-dpp2 wrapper migration (e.g., IdentityCreditWithdrawalTransitionWasm) round-trips correctly from the JS SDK perspective.

Prior finding reconciliation: #1 (runbook leak in docs/v12-upgrade-boundary-risks.md) STILL VALID — file at lines 119-135 still contains the self-labelled 'do not commit' section with live HPMN validator IP, ansible user, and operator SSH key path; BLOCKING. #2 (wasm-dpp2 TS type vs runtime $type/$kind) STILL VALID — proof.rs:18-38 still declares type discriminator and the doc-comment still says #[serde(tag = "type")], while rs-dpp asset_lock_proof/mod.rs:38,49 uses $type; BLOCKING. #3 (TokenPricingSchedule raw u64) STILL VALID — no json_safe_fields, tests pin raw numeric shape; SUGGESTION. #4 (TokenDistributionInfo unpinned variants) STILL VALID — only PreProgrammed pinned; SUGGESTION. #5 (ArrayItemType Boolean/Date unpinned) STILL VALID — only 5 of 7 variants pinned; SUGGESTION. New delta finding: the rewritten lenient constructor at wasm-dpp/.../data_contract_update_transition/mod.rs:52-79 defaults $formatVersion/userFeeIncrease/signaturePublicKeyId/signature but does not default or alias $identity-contract-nonce, which is a required serde field; two still-checked-in JS specs construct the transition without it.

blocking: Committed runbook self-labelled 'do not commit' discloses live HPMN validator IP, SSH user, and operator SSH key path

docs/v12-upgrade-boundary-risks.md (line 119-135)

STILL VALID at head a592d79. The section heading at line 119 reads ## Runbook (local only — contains infra details, do not commit), but the body publishes operator-sensitive infrastructure metadata the author themselves marked as private:

• hp-masternode-8 = 68.67.122.8 is identified as a live HPMN testnet validator with ansible_user ubuntu and do NOT stop the drive container annotation.
• 54.185.219.212 is identified as a disposable mainnet-synced node.
• SSH access template is published verbatim: ssh -i ~/.ssh/evo-app-deploy.rsa ubuntu@<host> — exposing both the SSH username and the operator's private-key filename (evo-app-deploy.rsa).
• Volume layout (docker volume ls | grep -i drive, tar strategy) gives an attacker a reliable map of the live drive container.

This content is entirely unrelated to the JSON/Value unification work this PR is about and the author's own heading explicitly classifies it as not-for-commit. Pairing operator workflow + key-file paths with named live infra is materially more useful for credential-phishing or social-engineering than each fact in isolation. Remove the runbook section before merge; keep operator runbooks in a private store. Consider rotating evo-app-deploy.rsa out of caution.

blocking: wasm-dpp2 TypeScript declarations advertise `type`/`kind` while rs-dpp runtime emits `$type`/`$kind`

packages/wasm-dpp2/src/asset_lock_proof/proof.rs (line 18-38)

STILL VALID at head a592d79. The #[wasm_bindgen(typescript_custom_section)] at proof.rs:23-37 declares AssetLockProofObject/AssetLockProofJSON as { type: "instant" | "chain" } & ... and the doc-comment at line 25 still says #[serde(tag = "type")]. The actual rs-dpp enum at packages/rs-dpp/src/identity/state_transition/asset_lock_proof/mod.rs:38,49 uses #[serde(tag = "$type", rename_all = "camelCase")], and the wasm-dpp2 JS unit specs updated earlier in this PR assert $type on the runtime objects.

The same mismatch persists across this PR's TS sections: packages/wasm-dpp2/src/voting/winner_info.rs:18-28, packages/wasm-dpp2/src/voting/vote_poll.rs:39,50, packages/wasm-dpp2/src/voting/resource_vote_choice.rs:19-29, packages/wasm-dpp2/src/shielded/address_witness.rs:17,25,39,47, packages/wasm-dpp2/src/platform_address/fee_strategy.rs:18-30, and packages/wasm-dpp2/src/group/token_event.rs — all corresponding to rs-dpp enums migrated to serde(tag = "$type") / serde(tag = "$kind") by 7f63b89.

Net effect for wasm-dpp2 consumers compiling against the published .d.ts:

1. JSON.parse(json).type is undefined; the discriminator is at $type.
2. Every TS discriminated-union narrowing case "instant": resolves to never.
3. JS code constructing { type: "instant", ... } per the TS declaration is rejected by from_object/fromJSON strict deserialization.

Sync each typescript_custom_section literal and the Mirrors the rs-dpp serde shape doc-comment to the runtime tag ($type, and $kind for GroupAction). Also update CONVENTIONS.md / any Mirrors the rs-dpp serde shape (... "type" ...) text in matching JS doc-comments.

suggestion: Lenient constructor does not default or alias `$identity-contract-nonce`, breaking existing JS callers

packages/wasm-dpp/src/data_contract/state_transition/data_contract_update_transition/mod.rs (line 52-79)

Introduced by the latest delta. The rewritten constructor calls strict DataContractUpdateTransition::from_object(raw) after defaulting $formatVersion, userFeeIncrease, signaturePublicKeyId, and signature for legacy callers, but does not handle the identity_contract_nonce field — required at packages/rs-dpp/src/state_transition/state_transitions/contract/data_contract_update_transition/v0/mod.rs:33-38 with the serde rename "$identity-contract-nonce".

Two existing JS specs construct new DataContractUpdateTransition({...}) without that field at packages/wasm-dpp/test/integration/dataContract/stateTransition/DataContractUpdateTransition/validation/basic/validateDataContractUpdateTransitionBasicFactory.spec.js:47-52 and packages/wasm-dpp/test/unit/dataContract/stateTransition/DataContractUpdateTransition/validation/state/validateDataContractUpdateTransitionStateFactory.spec.js:40-43. Strict from_object will reject these with a missing-field error. The one spec updated in this delta (DataContractUpdateTransition.spec.js:24) had to add the canonical key explicitly, confirming the breakage.

Either default the nonce to 0 alongside the other ensure_* calls if the legacy constructor was previously permissive about its absence, or update/skip the two remaining specs to supply the canonical key. If a legacy camelCase alias (identityContractNonce) was ever supported by the pre-canonical lenient path, translate it to the canonical name as part of the ensure_* block.

suggestion: TokenPricingSchedule canonical JSON emits raw u64 — JS clients silently round Credits above 2^53−1

packages/rs-dpp/src/tokens/token_pricing_schedule.rs (line 28-51)

STILL VALID at head a592d79. TokenPricingSchedule (lines 28-45) derives plain Serialize/Deserialize with no #[json_safe_fields], and the canonical impls (lines 48, 51) are blanket impls with no Repr wrapper. The variants SinglePrice(Credits) and SetPrices(BTreeMap<TokenAmount, Credits>) both expose raw u64 on the JSON wire surface; the tests at lines 100-123 pin the raw numeric shape {"SinglePrice": 1234} / {"SetPrices": {"5": 50, "10": 80}}.

This PR establishes a stated #[json_safe_fields] convention applied to 25+ V0/V1 struct leaves to protect JS clients from silently rounding u64 values above 2^53−1. Token prices use the 100-billion-per-Dash credit scale (per CLAUDE.md), so a tier price above ~92,233 DASH (~9.2 × 10^15 duffs) drops precision when round-tripped through JsonConvertible::to_json and consumed by JSON.parse on the JS side. Because TokenPricingSchedule is referenced from TokenConfiguration distribution rules, this can manifest as off-by-rounding fees with no JS-side error.

Apply #[json_safe_fields] (or a Repr wrapper with json_safe_u64 on the inner Credits/TokenAmount fields) so JS receives the decimal-string form, matching the convention applied throughout this PR.

suggestion: TokenDistributionInfo round-trip tests only pin PreProgrammed; Perpetual and TokenDistributionTypeWithResolvedRecipient unpinned

packages/rs-dpp/src/data_contract/associated_token/token_distribution_key.rs (line 322-389)

STILL VALID at head a592d79. mod json_convertible_tests_token_distribution_info (lines 322-389) defines a single fixture TokenDistributionInfo::PreProgrammed(1_700_000_000_000, Identifier::new([0x42; 32])) and pins both JSON and Value wire shapes only for that variant. The Perpetual { moment, recipient } variant — where moment is RewardDistributionMoment (an internally-tagged enum migrated to $type in 51d3193) and recipient is TokenDistributionRecipient — is not pinned, and TokenDistributionTypeWithResolvedRecipient (the resolved-recipient wrapper with its own $type-tagged repr) is also missing canonical wire-shape pins.

The broader internally-tag everything with $type sweep is the consensus-critical change being landed here; the unpinned Perpetual variant is exactly where a future regression (missing tag = "$type" or a silent variant-flip on a nested enum) would land without a fixture there to catch it. Mirror the PreProgrammed test for at least one Perpetual case (e.g. BlockBasedTimeInterval) and one TokenDistributionTypeWithResolvedRecipient case.

suggestion: ArrayItemType canonical round-trip tests miss Boolean and Date variants

packages/rs-dpp/src/data_contract/document_type/property/array.rs (line 706-842)

STILL VALID at head a592d79. mod json_convertible_tests (lines 712-842) pins JSON + Value wire shapes for only five of ArrayItemType's seven variants: Integer (716, 782), Number (729, 793), String (740, 804), ByteArray (757, 819), and Identifier (771, 833). The two unit variants Boolean and Date have no canonical wire-shape pin in either path.

This was the last enum landed in the internally tag everything with $type sweep (commit c341be6) and is the consensus-critical schema-definition surface for document contracts; a future serde-rename slip on Boolean ({"$type":"boolean"} vs {"$type":"bool"}) would silently change contract document schemas with no test failure.

Add two more tests symmetric to the existing pattern, one each for ArrayItemType::Boolean and ArrayItemType::Date, asserting the JSON and Value layers.

Code Review

Verified at head ed30168. Latest delta is a small feature-gating repair: ungates crate::serialization::serde_bytes so it compiles in every feature configuration (now needed by always-serde ExtendedBlockInfoV0.signature: [u8; 96]) and removes erroneous #[cfg(feature = "json-conversion"|"value-conversion")] gates from state-transition submodules so rs-dapi (state-transitions-only) compiles. No new defects introduced. All six coordinator-prior-findings re-verified against current head: prior-1, prior-2, prior-3, prior-4, prior-5, prior-6 are STILL VALID and carried forward unchanged. The codex-security latest-delta finding on bounded byte deserialization is dropped as speculative pre-existing hardening unrelated to this PR's scope.

Re-verified at head ed30168 — file unchanged by the latest delta. The section heading itself reads ## Runbook (local only — contains infra details, do not commit), but the body then publishes operator-sensitive metadata: live testnet HPMN validator hp-masternode-8 = 68.67.122.8 (explicitly identified as a producing validator: "do NOT stop the drive container"), a second host IP 54.185.219.212, SSH user ubuntu, the operator's SSH key path ~/.ssh/evo-app-deploy.rsa, and step-by-step ssh/scp extraction commands. dashpay/platform is a public repository — anyone reading this PR (or the git history once it lands) gets a confirmed live validator IP, the SSH account name, the exact key filename, and confirmation of the validator's Docker layout. This is meaningful reconnaissance against the operator and contradicts the author's own privacy marker. The runbook is also out of scope for the JSON/Value unification work.

TS consumers constructing { type: "instant", … } will fail rs-dpp deserialization at the wasm boundary; consumers branching on obj.type will never match the runtime shape (which carries $type). Worse, the TS type permits objects with both type and $type present, allowing a UI/TS layer to think it's signing one variant while the runtime dispatches on $type and produces the other — exactly the cross-variant confusion the $type rename was meant to prevent. Same divergence pattern likely exists across other wasm-dpp2 typescript_custom_section blocks (winner_info, resource_vote_choice, vote_poll, fee_strategy, address_witness, token_event) — sweep with grep before merge.

suggestion: Lenient constructor does not default or alias `identityContractNonce`, breaking legacy JS callers

packages/wasm-dpp/src/data_contract/state_transition/data_contract_update_transition/mod.rs (line 52)

Re-verified at head ed30168 — file unchanged by the latest delta. The rewritten constructor defaults $formatVersion, userFeeIncrease, signaturePublicKeyId, and signature to keep legacy partial JS input passing the strict from_object(raw) canonical deserializer, but does NOT default or alias the canonical required field identityContractNonce (renamed from the legacy hyphenated $identity-contract-nonce form at packages/rs-dpp/src/state_transition/state_transitions/contract/data_contract_update_transition/v0/mod.rs:31-36). External JS consumers that historically passed identityContractNonce / identity_contract_nonce / $identity-contract-nonce, or that omitted the field entirely (intending to set it later via a setter), will now fail at construction with an opaque missing-field error. Because this is replay-protection state, do NOT silently default it to zero — instead, accept the legacy aliases and rename them to the canonical key before calling from_object, so legacy callers continue to work without weakening the nonce contract.

suggestion: TokenPricingSchedule canonical JSON emits raw u64 — JS clients silently round Credits above 2^53−1

packages/rs-dpp/src/tokens/token_pricing_schedule.rs (line 28)

Re-verified at head ed30168 — file unchanged by the latest delta. TokenPricingSchedule derives plain Serialize/Deserialize (no #[json_safe_fields] attribute) and the canonical impls at lines 48 and 51 are blanket impls with no SafeU64/Repr wrapper. The variants SinglePrice(Credits) and SetPrices(BTreeMap<TokenAmount, Credits>) carry u64 aliases that round-trip through serde_json::Value::Number(u64), which JavaScript silently rounds above Number.MAX_SAFE_INTEGER (2^53 − 1 ≈ 9.0e15). Token pricing carries Credits (1 DASH = 10^11 credits, so ~90 000 DASH exceeds the safe range) — this is exactly the JS-large-integer hazard the rest of this PR's #[json_safe_fields] rollout (25+ V0/V1 leaves) was designed to prevent. A wallet UI fetching a pricing schedule via the JS SDK can silently round the displayed price, leading to a user authorizing one price while the underlying transition charges another. Apply #[json_safe_fields] (or equivalent serde(with = "...") SafeU64 wrappers) consistent with the rest of the codebase.

suggestion: TokenDistributionInfo round-trip tests only pin PreProgrammed; Perpetual + TokenDistributionTypeWithResolvedRecipient unpinned

packages/rs-dpp/src/data_contract/associated_token/token_distribution_key.rs (line 322)

Re-verified at head ed30168 — test module unchanged by the latest delta. mod json_convertible_tests_token_distribution_info defines a single fixture TokenDistributionInfo::PreProgrammed(1_700_000_000_000, Identifier::new([0x42; 32])) and pins both JSON and Value wire shapes only for that variant. The Perpetual variant of TokenDistributionInfo and every variant of the sibling enum TokenDistributionTypeWithResolvedRecipient are unpinned. TokenDistributionInfo controls who receives newly distributed tokens and when, so a future serde/tag-shape regression on these variants is a token-routing risk that the current test matrix would not catch. Add literal json!{} / platform_value!{} assertions per variant following the established pattern at lines 340-388.

suggestion: ArrayItemType canonical round-trip tests miss Boolean and Date variants

packages/rs-dpp/src/data_contract/document_type/property/array.rs (line 706)

Re-verified at head ed30168 — test module unchanged by the latest delta. mod json_convertible_tests (lines 712-842) pins JSON + Value wire shapes for only five of ArrayItemType's seven variants: Integer, Number, String, ByteArray, Identifier. The unit variants Boolean and Date remain unpinned. These shape a document property's array-element type and feed the schema validator; a silent wire-shape regression (e.g. boolean → bool, date → dateTime) would not be caught. Add four short tests mirroring the existing json_round_trip_integer_variant / value_round_trip_integer_variant patterns so the full 7-variant enum is locked in.

Code Review

Re-verified all six coordinator-supplied prior findings against head a496b0b — every one is STILL VALID and carried forward. The latest delta (ed30168..a496b0b) is dominated by a v3.1-dev merge of ~400 unrelated files; it did not touch any of the prior-flagged lines. Beyond carry-forwards, this verification also confirms a systematic type vs $type discriminator mismatch across multiple wasm-dpp2 TypeScript custom sections (the same root cause as prior-2 in proof.rs, now confirmed in fee_strategy.rs, vote_poll.rs, resource_vote_choice.rs, winner_info.rs, address_witness.rs, and the TokenEvent doc-comment) — rs-dpp custom Serialize impls emit $type everywhere but the public TS surface advertises type. Consolidated into one additional blocking finding to stay within the 10-finding budget. The Swift identityToHandle dangling-pointer issue raised by codex-ffi-engineer is real but lives in a pre-existing file untouched by this PR's own commits (introduced by upstream PRs pulled in via the v3.1-dev merge) and is out of scope for this PR's stated JSON/Value conversion goal.

blocking: Committed runbook self-labelled 'do not commit' discloses live HPMN validator IP, SSH user, and operator key path

docs/v12-upgrade-boundary-risks.md (line 119)

Re-verified at HEAD a496b0b — file unchanged by the v3.1-dev merge delta. The section heading at L119 itself reads ## Runbook (local only — contains infra details, do not commit), yet the body (L121–135) publishes operator-sensitive metadata into a public-repo branch staged for merge: live testnet HPMN validator hp-masternode-8 = 68.67.122.8, secondary host 54.185.219.212, SSH user ubuntu, operator key path ~/.ssh/evo-app-deploy.rsa, and step-by-step ssh/scp extraction commands targeting the drive volume. The 'do not commit' caveat in the heading does not undo the disclosure once committed.

Remove this section from the PR (move to private/local-only storage). Because the branch was pushed to GitHub, content may already be indexed; consider history rewrite and rotation of the named SSH key, and review whether the named validator host needs hardening.

blocking: TypeScript declarations for AssetLockProof advertise `type` while rs-dpp runtime emits `$type`

packages/wasm-dpp2/src/asset_lock_proof/proof.rs (line 18)

Re-verified at HEAD a496b0b — file unchanged by the latest delta. The typescript_custom_section (L19–38) declares AssetLockProofObject / AssetLockProofJSON as unions discriminated by type, and the in-file doc-comment claims rs-dpp uses #[serde(tag = "type")]. The actual rs-dpp source at packages/rs-dpp/src/identity/state_transition/asset_lock_proof/mod.rs:38,49 is #[serde(tag = "$type", rename_all = "camelCase")] for both AssetLockProof Serialize and RawAssetLockProof Deserialize.

Consequences across the wasm boundary:

• TS callers constructing { type: "instant", ... } produce objects the rs-dpp Deserialize rejects (or treats the type field as a non-tag map entry).
• TS callers branching on proof.type never see the actual $type discriminator and silently take the wrong branch — chain-locked proofs could be treated as instant-locked.

Update both TS aliases and the doc-comment to use $type so the public TS surface matches the wire shape (consistent with AddressWitness / AddressFundsFeeStrategyStep conventions).

blocking: Systematic `type` vs `$type` discriminator mismatch across wasm-dpp2 TypeScript custom sections

packages/wasm-dpp2/src/platform_address/fee_strategy.rs (line 8)

The same root-cause defect that affects AssetLockProof exists in at least five additional wasm-dpp2 TypeScript surfaces. In every case the rs-dpp custom Serialize impl emits $type, but the exported TS declaration declares type:

• packages/wasm-dpp2/src/platform_address/fee_strategy.rs:17-19,28-30 — TS declares { type: "deductFromInput"|"reduceOutput"; index: number }; rs-dpp at packages/rs-dpp/src/address_funds/fee_strategy/mod.rs:42,46,99 serializes/deserializes $type via a custom Visitor that errors with missing_field("$type").
• packages/wasm-dpp2/src/voting/vote_poll.rs:38-44,49-55 — TS declares type: "contestedDocumentResourceVotePoll"; rs-dpp at packages/rs-dpp/src/voting/vote_polls/mod.rs:29 uses serde(tag = "$type", rename_all = "camelCase"). The neighboring doc-comment even contradicts the code by claiming the tag is plain type.
• packages/wasm-dpp2/src/voting/resource_vote_choice.rs:18-21,26-29 — TS declares { type: "towardsIdentity"|"abstain"|"lock"; ... }; rs-dpp's custom Serialize at packages/rs-dpp/src/voting/vote_choices/resource_vote_choice/mod.rs:47,53,58,85,103 keys on $type.
• packages/wasm-dpp2/src/voting/winner_info.rs:17-20,25-28 — TS declares { type: "noWinner"|"locked"|"wonByIdentity"; ... }; rs-dpp at packages/rs-dpp/src/voting/vote_info_storage/contested_document_vote_poll_winner_info/mod.rs:31,36,42,70,88 keys on $type (and its own internal tests assert "$type": "wonByIdentity").
• packages/wasm-dpp2/src/shielded/address_witness.rs:16-49 — TS declares type: "p2pkh"|"p2sh"; rs-dpp at packages/rs-dpp/src/address_funds/witness.rs:32 is serde(tag = "$type").
• packages/wasm-dpp2/src/group/token_event.rs:7-46 — TS interface is permissive ({ type: string; [field: string]: unknown }), but every example in the doc-comment uses { type: ... } while the rs-dpp custom Serialize at packages/rs-dpp/src/tokens/token_event.rs:194,202,210,217,... emits "$type". Typed callers following the doc-comment will build undeserializable events.

The failure mode is identical across all of these: JS callers construct or branch on obj.type while the runtime object only has $type. Either the wire shape is wrong and rs-dpp should emit type (consistent with the in-tree vote_poll doc-comment), or the TS declarations are wrong and should advertise $type (consistent with the AddressWitness/AddressFundsFeeStrategyStep convention the rest of this PR cites). Pick one and align all sites — leaving them divergent guarantees silent client/server disagreement across the wasm boundary on every one of these enums.

suggestion: Lenient constructor does not default or alias `identityContractNonce`, breaking legacy JS callers

packages/wasm-dpp/src/data_contract/state_transition/data_contract_update_transition/mod.rs (line 52)

Re-verified at HEAD a496b0b — file unchanged by the latest delta. The rewritten constructor (L62–75) builds a lenient pre-pass that ensures $formatVersion, userFeeIncrease, signaturePublicKeyId, and signature are present before delegating to strict DataContractUpdateTransition::from_object(raw). But identityContractNonce is canonical-required and is neither defaulted nor aliased from legacy spellings (e.g. $identity-contract-nonce / identity_contract_nonce). Existing JS callers that previously constructed a transition from minimal inputs and signed it afterwards will now hit from_object failure on construction.

Do NOT default to zero — zero is a valid nonce, and silently substituting it would let unsigned/wrong-nonce transitions through with replay/ordering risk. Either accept the legacy alias by remapping it to identityContractNonce before from_object, or document the migration explicitly in the PR's migration notes so consumers know to rename.

suggestion: TokenPricingSchedule canonical JSON emits raw u64 — JS clients silently round Credits above 2^53−1

packages/rs-dpp/src/tokens/token_pricing_schedule.rs (line 28)

Re-verified at HEAD a496b0b — file unchanged by the latest delta. TokenPricingSchedule derives plain Serialize/Deserialize (L28) with no #[json_safe_fields] attribute, and the JsonConvertible/ValueConvertible impls (L48, L51) are blanket impls with no SafeU64/Repr wrapper.

SinglePrice(Credits) and SetPrices(BTreeMap<TokenAmount, Credits>) both carry u64 aliases. When the canonical JSON is consumed by JS at the wasm boundary, any value above Number.MAX_SAFE_INTEGER (2^53 − 1 ≈ 9.007e15) will silently lose precision. Credit-denominated values for tokens can easily exceed that bound (1 Dash = 1e11 credits, so 100k Dash worth = 1e16 credits, past the safe range). A wallet quoting a price or signing a direct-purchase transition could end up agreeing to different economic terms than the contract author signed.

The PR established #[json_safe_fields] as the canonical convention for large-integer protection. This type should adopt it to be consistent with the 25+ V0/V1 leaves the PR description claims now carry it.

suggestion: TokenDistributionInfo round-trip tests only pin PreProgrammed; Perpetual + TokenDistributionTypeWithResolvedRecipient unpinned

packages/rs-dpp/src/data_contract/associated_token/token_distribution_key.rs (line 322)

Re-verified at HEAD a496b0b — test module unchanged. mod json_convertible_tests_token_distribution_info (L322–389) defines a single fixture: TokenDistributionInfo::PreProgrammed(...). Only that variant has JSON and Value wire-shape pinning. The Perpetual variant of TokenDistributionInfo and the related TokenDistributionTypeWithResolvedRecipient enum (also in this file) are unpinned.

This is the same wire-shape regression risk the PR sets out to prevent for all canonical types — a future refactor of either unpinned variant (rename, tag change, field reorder) can silently break the wire shape without any test failing. Add two more fixture-and-assert tests (one for Perpetual, one for the resolved-recipient enum) to match the convention established by ~85 tests elsewhere in the PR.

suggestion: ArrayItemType canonical round-trip tests miss Boolean and Date variants

packages/rs-dpp/src/data_contract/document_type/property/array.rs (line 706)

Re-verified at HEAD a496b0b — test module unchanged. The ArrayItemType enum (L9–17) has seven variants: Integer, Number, String, ByteArray, Identifier, Boolean, Date. The json_convertible_tests module (L706–842) pins JSON + Value wire shapes for only the first five — Boolean and Date are uncovered.

Both missing variants have production callers that branch on type (Date even has special I64→U64 coercion at L168 in this same file), so any silent rename or tag-shape change is a real wire-shape regression risk. Add the four missing tests (json + value × Boolean + Date) to close the symmetry the rest of the module establishes.

Summary

Incremental delta a496b0b..955e5ea is comment-only and fixes none of the prior review findings. All seven prior findings are STILL VALID at current HEAD; two additional in-scope suggestions were verified in the cumulative PR surface.

Verified findings

1. blocking: Committed local runbook exposes live validator infrastructure details

docs/v12-upgrade-boundary-risks.md:119-135

Prior status: STILL VALID. This section is explicitly labeled local-only and 'do not commit', but it is checked into the PR and publishes live HPMN/testnet host information, a second host IP, SSH username, operator key path, and concrete ssh/scp dump commands. That is operator-sensitive reconnaissance material in a public repository branch and should not ship with the JSON/Value conversion work. Remove the runbook from the PR and treat the already-pushed host/key details as exposed.

2. blocking: AssetLockProof TypeScript declarations advertise `type` while rs-dpp uses `$type`

packages/wasm-dpp2/src/asset_lock_proof/proof.rs:18-38

Prior status: STILL VALID. The exported TypeScript custom section tells JS callers to construct and inspect AssetLockProof objects with a plain type discriminator, and the comment claims rs-dpp uses #[serde(tag = "type")]. The actual rs-dpp enum and raw deserializer use #[serde(tag = "$type", rename_all = "camelCase")], so callers following these typings will send objects the Rust side rejects and will branch on a field that runtime output does not contain. Align the TS declarations and comments with the executable $type wire shape.

export type AssetLockProofObject =

export type AssetLockProofJSON =
    | ({ $type: "instant" } & InstantAssetLockProofJSON)
    | ({ $type: "chain" } & ChainAssetLockProofJSON);
"#;

3. blocking: Additional wasm-dpp2 TypeScript surfaces still use `type` instead of `$type`

packages/wasm-dpp2/src/platform_address/fee_strategy.rs:8-31

Prior status: STILL VALID. This same discriminator mismatch appears beyond AssetLockProof. FeeStrategyStepObject and FeeStrategyStepJSON declare { type: ... }, while AddressFundsFeeStrategyStep serializes $type and its deserializer errors on missing $type; the same stale plain-type pattern remains in VotePoll, ResourceVoteChoice, ContestedDocumentVotePollWinnerInfo, AddressWitness, and TokenEvent TypeScript custom sections or examples. These are public JS contracts for the new canonical conversion surface, so they must match the runtime objects emitted and accepted by rs-dpp.

4. suggestion: Lenient update-transition constructor no longer accepts legacy nonce field

packages/wasm-dpp/src/data_contract/state_transition/data_contract_update_transition/mod.rs:52-79

Prior status: STILL VALID. The constructor now pre-fills $formatVersion, userFeeIncrease, signaturePublicKeyId, and signature before strict from_object, but it does not map the previous JS constructor field identityContractNonce to the canonical serde field $identity-contract-nonce. The PR even changes the existing JS test fixture from identityContractNonce to $identity-contract-nonce, which means existing callers following the old public constructor shape will fail construction. Keep requiring a real nonce, but alias the legacy field or document the migration explicitly.

5. suggestion: TokenPricingSchedule JSON conversion emits u64 prices as unsafe JS numbers

packages/rs-dpp/src/tokens/token_pricing_schedule.rs:28-51

Prior status: STILL VALID. TokenPricingSchedule derives plain serde and its JsonConvertible/ValueConvertible impls do not use json_safe_fields or an equivalent wrapper, so SinglePrice(Credits) and SetPrices(BTreeMap<TokenAmount, Credits>) serialize credit and token amounts as raw JSON numbers. Those u64 values can exceed JavaScript's safe integer range, causing wasm/JS callers to round token prices or thresholds silently. Apply the same large-integer-safe JSON convention used elsewhere in this PR's conversion sweep.

6. suggestion: TokenDistributionInfo tests pin only the PreProgrammed wire shape

packages/rs-dpp/src/data_contract/associated_token/token_distribution_key.rs:322-389

Prior status: STILL VALID. The canonical conversion tests for TokenDistributionInfo use only a PreProgrammed fixture, leaving the Perpetual variant unpinned. The related TokenDistributionTypeWithResolvedRecipient enum also has JsonConvertible/ValueConvertible impls but no literal wire-shape tests. Add fixture assertions for the missing variants so future tag, field, or payload-shape changes fail in the test suite.

7. suggestion: ArrayItemType conversion tests miss Boolean and Date variants

packages/rs-dpp/src/data_contract/document_type/property/array.rs:706-842

Prior status: STILL VALID. ArrayItemType has seven variants, but the canonical JSON/Value tests only pin Integer, Number, String, ByteArray, and Identifier. Boolean and Date are still uncovered, even though Date has dedicated conversion behavior in this file. Add JSON and Value wire-shape assertions for both variants to complete the variant matrix introduced by this PR.

8. suggestion: C/Swift data-contract JSON no longer uses the SDK protocol version

packages/rs-sdk-ffi/src/data_contract/queries/fetch_with_serialization.rs:110-112

New finding. This PR changed the FFI JSON path from contract.to_json(wrapper.sdk.version()) to serde_json::to_value(&contract). DataContract's serde impl explicitly calls PlatformVersion::get_version_or_current_or_latest(None), so the JSON returned to C/Swift can now be serialized with process current/latest platform version instead of the version pinned on this SDK handle. The same regression is present in fetch_json.rs; build DataContractInSerializationFormat with wrapper.sdk.version() before serializing JSON across the FFI boundary.

9. suggestion: BLS public-key sequence deserialization allocates unbounded input before rejecting it

packages/rs-dpp/src/serialization/dashcore/bls_pubkey.rs:151-157

New finding. The new BLS public-key serde wrapper accepts byte sequences for JSON/Value round-trips, but visit_seq pushes every element into a Vec and only checks that the length is exactly 48 after the sequence ends. A malformed payload with a very large array in a public-key slot forces unnecessary allocation and parsing before the deserializer can reject it. Stop as soon as more than 48 bytes are seen.

    fn visit_seq<A: serde::de::SeqAccess<'de>>(self, mut seq: A) -> Result<Self::Value, A::Error> {
        let mut bytes = Vec::with_capacity(COMPRESSED_G1_LEN);
        while let Some(b) = seq.next_element::<u8>()? {
            if bytes.len() >= COMPRESSED_G1_LEN {
                return Err(serde::de::Error::custom(format!(
                    "expected {COMPRESSED_G1_LEN} compressed-G1 bytes for public key, got more"
                )));
            }
            bytes.push(b);
        }
        from_compressed_g1_bytes(&bytes)
    }

Dropped / out-of-scope observations

• JS→Rust boundary: 32-byte Uint8Array silently re-typed as Value::Identifier — Out of scope for this PR. The heuristic is pre-existing and was not introduced or newly relied on by the JSON/Value conversion changes under review.
• JS→Rust boundary: f64 as u64 cast loses precision silently above 2^53 — Out of scope for this PR. The conversion behavior predates the reviewed changes and should be handled as a separate wasm input-boundary cleanup.
• Pre-existing AssetLockProof variant getters can panic from JS — Out of scope for this PR. The panicking getters predate the conversion-surface changes and are not part of the current delta.
• C-FFI string return-value ownership documentation should name the free routine — Dropped as routine adjacent documentation cleanup. It is not required for the JSON/Value conversion surface to work and does not affect this review action.

  Prior status: STILL VALID. `ArrayItemType` has seven variants, but the canonical JSON/Value tests only pin Integer, Number, String, ByteArray, and Identifier. Boolean and Date are still uncovered, even though Date has dedicated conversion behavior in this file. Add JSON and Value wire-shape assertions for both variants to complete the variant matrix introduced by this PR.
- [SUGGESTION] In `packages/rs-sdk-ffi/src/data_contract/queries/fetch_with_serialization.rs`:110-112: C/Swift data-contract JSON no longer uses the SDK protocol version
  New finding. This PR changed the FFI JSON path from `contract.to_json(wrapper.sdk.version())` to `serde_json::to_value(&contract)`. `DataContract`'s serde impl explicitly calls `PlatformVersion::get_version_or_current_or_latest(None)`, so the JSON returned to C/Swift can now be serialized with process current/latest platform version instead of the version pinned on this SDK handle. The same regression is present in `fetch_json.rs`; build `DataContractInSerializationFormat` with `wrapper.sdk.version()` before serializing JSON across the FFI boundary.
- [SUGGESTION] In `packages/rs-dpp/src/serialization/dashcore/bls_pubkey.rs`:151-157: BLS public-key sequence deserialization allocates unbounded input before rejecting it
  New finding. The new BLS public-key serde wrapper accepts byte sequences for JSON/Value round-trips, but `visit_seq` pushes every element into a Vec and only checks that the length is exactly 48 after the sequence ends. A malformed payload with a very large array in a public-key slot forces unnecessary allocation and parsing before the deserializer can reject it. Stop as soon as more than 48 bytes are seen.

Code Review

Automated review for 6e5d5683.

Body-only fallback: GitHub refused PR diff retrieval for this PR (>300 files), so inline mapping was impossible; posting the same verifier-approved findings as an exact-SHA body-only review.

Summary

Incremental review against head 6e5d568. Reconciled all 9 prior findings against current code: all 9 are STILL VALID and verified in place. The latest delta restores DataContract validate-by-default Deserialize (with explicit from_json(_, false, _) opt-out) and a behavior pin — that change is internally consistent and correct, so codex-general's new claim that it is a blocking bug is dropped as a false positive. No new in-scope findings emerged. Two blocking issues (committed live-infra runbook; wasm-dpp2 TS type vs runtime $type) gate this PR.

Carried-forward prior findings

blocking: Committed local runbook exposes live validator infrastructure details

docs/v12-upgrade-boundary-risks.md:119-135

This runbook section is explicitly labeled local only — contains infra details, do not commit, yet it has been checked into the PR. It publishes a live testnet HPMN validator hostname and IP (hp-masternode-8 = 68.67.122.8), a second mainnet-synced host IP (54.185.219.212), the SSH user (ubuntu), the operator key path (~/.ssh/evo-app-deploy.rsa), and the concrete ssh/scp commands used to reach them. That is operator-sensitive reconnaissance material that should not ship in a public branch, and it is unrelated to the JSON/Value conversion work this PR is about. Remove the entire ## Runbook (local only ...) section before merge and treat the already-pushed host/key details as exposed (rotate the deploy key, audit access on the named hosts).

blocking: AssetLockProof TypeScript declarations advertise `type` while rs-dpp uses `$type`

packages/wasm-dpp2/src/asset_lock_proof/proof.rs:18-38

The exported TypeScript custom section tells JS callers to construct and inspect AssetLockProofObject / AssetLockProofJSON with a plain type discriminator, and the doc comment claims rs-dpp uses #[serde(tag = "type")]. The actual rs-dpp enum at packages/rs-dpp/src/identity/state_transition/asset_lock_proof/mod.rs:38,49 uses #[serde(tag = "$type", rename_all = "camelCase")]. Callers following these public typings will construct objects the Rust side rejects on from_object / fromJSON and will branch on a runtime field that does not exist. Align the TS declarations and surrounding comments with the executable $type wire shape.

blocking: Additional wasm-dpp2 TypeScript surfaces still use `type` instead of `$type`

packages/wasm-dpp2/src/platform_address/fee_strategy.rs:8-31

Same discriminator mismatch beyond AssetLockProof. FeeStrategyStepObject and FeeStrategyStepJSON declare { type: "deductFromInput" | "reduceOutput"; index }, but the runtime serde in packages/rs-dpp/src/address_funds/fee_strategy/mod.rs emits and requires $type (verified at lines 42, 46, 99, with round-trip tests at 131, 141, 148, 153, 206, 217, 237, 250). The same stale plain-type pattern remains in the wasm-dpp2 TS custom sections / examples for VotePoll, ResourceVoteChoice, ContestedDocumentVotePollWinnerInfo, AddressWitness, and TokenEvent. These are public JS contracts for the new canonical conversion surface — they must match the runtime objects rs-dpp emits and accepts.

suggestion: C/Swift data-contract JSON no longer pins the SDK protocol version

packages/rs-sdk-ffi/src/data_contract/queries/fetch_with_serialization.rs:110-131

This PR changed the FFI JSON path from contract.to_json(wrapper.sdk.version()) to serde_json::to_value(&contract) (line 111). DataContract's manual Serialize impl in packages/rs-dpp/src/data_contract/conversion/serde/mod.rs:48-60 resolves the version via PlatformVersion::get_version_or_current_or_latest(None), which reads process-global state and falls back to the latest known platform version. The JSON now crossing the C ABI to Swift is therefore governed by global state instead of the version pinned on the SDK handle the caller passed in (wrapper.sdk). In the same FFI result the bincode serialized_data is still produced through SDK-version-aware paths, so a divergence between json_string and serialized_data for the same contract is reachable. The same regression is in packages/rs-sdk-ffi/src/data_contract/queries/fetch_json.rs:54. Build DataContractInSerializationFormat with wrapper.sdk.version() and serialize that explicitly across the FFI boundary.

suggestion: Lenient update-transition constructor no longer accepts the legacy `identityContractNonce` field

packages/wasm-dpp/src/data_contract/state_transition/data_contract_update_transition/mod.rs:52-79

The constructor now pre-fills $formatVersion, userFeeIncrease, signaturePublicKeyId, and signature before strict DataContractUpdateTransition::from_object(raw) (lines 71-76), but it does not alias the previous JS public field identityContractNonce to the canonical serde field $identity-contract-nonce. This PR also rewrites the existing JS fixture from identityContractNonce to $identity-contract-nonce, so existing callers built against the old public constructor shape will fail with a missing-field error from the strict deserializer. Either alias the legacy key into the canonical key inside this Value::Map normalization step (keep requiring a real nonce — do not default it to zero), or document the field rename as a public migration in the PR.

suggestion: TokenPricingSchedule JSON emits u64 prices as unsafe JS numbers

packages/rs-dpp/src/tokens/token_pricing_schedule.rs:28-51

TokenPricingSchedule derives plain serde and its JsonConvertible / ValueConvertible impls (lines 48, 51) do not use json_safe_fields or an equivalent large-integer wrapper. As a result SinglePrice(Credits) and SetPrices(BTreeMap<TokenAmount, Credits>) serialize u64 credit and token amounts as raw JSON numbers. Values above Number.MAX_SAFE_INTEGER (2^53) will be silently rounded by JavaScript wasm/SDK callers that go through toJSON() — a financial-amount truncation in the same conversion sweep this PR introduces. Apply the safe-integer JSON convention used elsewhere in the PR to both variants.

suggestion: TokenDistributionInfo conversion tests pin only the PreProgrammed variant

packages/rs-dpp/src/data_contract/associated_token/token_distribution_key.rs:322-389

The canonical conversion tests for TokenDistributionInfo use only a PreProgrammed fixture (lines 336-388), leaving the Perpetual variant unpinned. The related TokenDistributionTypeWithResolvedRecipient enum also has JsonConvertible / ValueConvertible impls but no literal wire-shape tests. Wire-shape pinning is the central guarantee this PR introduces, so the variant matrix should be complete: add JSON and Value fixture assertions for Perpetual and for each variant of TokenDistributionTypeWithResolvedRecipient so a future tag, field, or payload-shape change fails loudly.

suggestion: ArrayItemType conversion tests miss Boolean and Date variants

packages/rs-dpp/src/data_contract/document_type/property/array.rs:706-842

ArrayItemType has seven variants but the new canonical conversion tests only pin Integer, Number, String, ByteArray, and Identifier. Boolean and Date are uncovered, even though Date has dedicated conversion behavior in this file. Add JSON and Value wire-shape assertions for both so the variant matrix introduced by this PR is complete.

suggestion: BLS public-key `visit_seq` collects unbounded input before rejecting it

packages/rs-dpp/src/serialization/dashcore/bls_pubkey.rs:151-157

The new BLS public-key serde wrapper accepts byte sequences for JSON/Value round-trips, but visit_seq pushes every element into a Vec and only checks the exact 48-byte (COMPRESSED_G1_LEN) length inside from_compressed_g1_bytes(&bytes) after the sequence ends. A malformed payload with a very large array in a public-key slot forces unnecessary allocation and parsing before the deserializer rejects it. This is currently reached only from trusted Dash Core validator data, but the with = "..." pattern is designed for reuse and the failure mode amplifies as soon as another type reuses this module on a less trusted ingest path. Cap the loop at COMPRESSED_G1_LEN + 1 and error on overflow so the structural promise ("48-byte key") is enforced inside the visitor.

    fn visit_seq<A: serde::de::SeqAccess<'de>>(self, mut seq: A) -> Result<Self::Value, A::Error> {
        let mut bytes = Vec::with_capacity(COMPRESSED_G1_LEN);
        while let Some(b) = seq.next_element::<u8>()? {
            if bytes.len() >= COMPRESSED_G1_LEN {
                return Err(serde::de::Error::custom(format!(
                    "expected {COMPRESSED_G1_LEN} compressed-G1 bytes for public key, got more"
                )));
            }
            bytes.push(b);
        }
        from_compressed_g1_bytes(&bytes)
    }

Dropped / false-positive observations

• DataContract serde deserialization validates despite the canonical no-validation contract (codex-general) — False positive. The latest commit (6e5d568 'fix(dpp)!: restore validate-by-default DataContract deserialize + from_json(bool)') is an intentional reversal — Deserialize validates by default and the explicit opt-out is from_json(_, false, _) / from_value(_, false, _). A pin test in packages/rs-dpp/src/data_contract/conversion/serde/mod.rs enforces the round-trip behavior. The PR description is stale relative to the shipped semantics, but the code is consistent with itself and with the new opt-out API. The claim that this breaks rs-scripts/src/bin/register_contract.rs is not load-bearing for the PR's stated goal, and the safer default for an SDK trust boundary is to validate. Independent security review (claude-security-auditor) reached the same conclusion.
• wasm-dpp2 fromJSON/fromObject expose full_validation: bool to JS callers with no safer-default helper (claude-security-auditor) — Defense-in-depth ergonomic suggestion only, not a defect. SDK-side validation is not trusted by Drive in any case. Treating it as a hard blocker would require a parallel API redesign on the JS surface that is outside this PR's scope.
• Pre-existing handle leak in dash_sdk_data_contract_fetch_with_serialization JSON error paths (claude-ffi-engineer) — Pre-existing on origin/v3.1-dev and not introduced or worsened by this PR. The PR only changed which JSON-conversion call sits inside the same error-return structure. Belongs in a separate FFI cleanup PR.
• Legacy wasm-dpp toJSON/toObject switched from PlatformVersion::first() to global current (claude-ffi-engineer) — Behavioral change is acknowledged by the PR's scope (canonical serde routes via PlatformVersion::get_version_or_current_or_latest) and the legacy wasm-dpp crate is documented as slated for deletion. Not gating; if there is a concrete JS consumer hitting a V0-vs-V1 shape regression, a focused follow-up makes more sense than backing out the unification here.
• Surplus address proof result omits JS-safe credit serialization in VerifiedAssetLockConsumedWithAddressInfos (codex-security-auditor) — Same root cause as the TokenPricingSchedule JS-safe-integer finding already kept (defense in depth across u64 financial fields). Folding it into one issue under the safe-integer sweep keeps the public review focused; tracking via the kept finding rather than as a separate suggestion.
• Audit remaining serde callsites that previously assumed no-validation Deserialize (claude-security-auditor) — Workspace-wide audit follow-up unrelated to PR-introduced behavior — out of scope for this dispatcher and not concrete enough to track here.

Code Review

Verified at head f574f8e. Latest delta from 6e5d568 is two rs-drive test-only call-site updates switching platform_value::from_value::<DataContract> to DataContract::from_value(_, false, platform_version) — no new findings, and no prior finding fixed. All 9 coordinator-prior-findings classified STILL VALID against the current tree (re-verified file/line evidence for the runbook leak, the wasm-dpp2 type vs rs-dpp $type discriminator gap on AssetLockProof and FeeStrategyStep, the FFI JSON path losing SDK-pinned version, the dropped identityContractNonce alias, the unsafe-integer leak in TokenPricingSchedule, the variant-coverage gaps in TokenDistributionInfo and ArrayItemType, and the unbounded visit_seq in the BLS pubkey wrapper). 9 in-scope findings carried forward; under the 10-finding budget.

The JSON crossing the C ABI to Swift is therefore governed by global state instead of the version pinned on the SDK handle the caller passed in (wrapper.sdk). In the same FFI result the bincode serialized_data is still produced through SDK-version-aware paths, so a divergence between json_string and serialized_data for the same contract is reachable. The same regression is in packages/rs-sdk-ffi/src/data_contract/queries/fetch_json.rs:54. Build a DataContractInSerializationFormat with wrapper.sdk.version() and serialize that explicitly across the FFI boundary so the version is pinned to the caller's SDK handle.

suggestion: Lenient update-transition constructor no longer accepts legacy `identityContractNonce` field

packages/wasm-dpp/src/data_contract/state_transition/data_contract_update_transition/mod.rs (line 52)

Re-verified at head f574f8e. The constructor pre-fills $formatVersion, userFeeIncrease, signaturePublicKeyId, and signature before strict DataContractUpdateTransition::from_object(raw) (lines 71–76), but it does not alias the previously-public JS field identityContractNonce into the canonical serde key $identity-contract-nonce. This PR also rewrites the existing JS fixture from identityContractNonce to $identity-contract-nonce, so existing callers built against the old public constructor shape will fail with a missing-field error from the strict deserializer. Either alias the legacy key into the canonical key inside this Value::Map normalization step (keep requiring a real nonce — do not default it to zero), or document the field rename as a public migration in the PR.

suggestion: TokenPricingSchedule JSON emits u64 prices as unsafe JS numbers

packages/rs-dpp/src/tokens/token_pricing_schedule.rs (line 28)

Re-verified at head f574f8e. TokenPricingSchedule derives plain serde at line 28 and its JsonConvertible / ValueConvertible impls (lines 48, 51) do not use json_safe_fields or an equivalent large-integer wrapper. As a result SinglePrice(Credits) and SetPrices(BTreeMap<TokenAmount, Credits>) serialize u64 credit and token amounts as raw JSON numbers. Values above Number.MAX_SAFE_INTEGER (2^53) will be silently rounded by JavaScript wasm/SDK callers that go through toJSON() — a financial-amount truncation introduced by the same conversion sweep this PR ships. Credits is a Dash credit amount (1 Dash = 1e11 credits), so prices above ≈90,071 Dash overflow JS safe-integer range. Apply the safe-integer JSON convention used elsewhere in the PR to both variants.

suggestion: TokenDistributionInfo conversion tests pin only the PreProgrammed variant

packages/rs-dpp/src/data_contract/associated_token/token_distribution_key.rs (line 322)

Re-verified at head f574f8e (lines 336–388 still use only a PreProgrammed fixture). The canonical conversion tests for TokenDistributionInfo leave the Perpetual variant unpinned. The related TokenDistributionTypeWithResolvedRecipient enum also has JsonConvertible / ValueConvertible impls but no literal wire-shape tests. Wire-shape pinning is the central guarantee this PR introduces, so the variant matrix should be complete: add JSON and Value fixture assertions for Perpetual and for each variant of TokenDistributionTypeWithResolvedRecipient so a future tag, field, or payload-shape change fails loudly.

suggestion: ArrayItemType conversion tests miss Boolean and Date variants

packages/rs-dpp/src/data_contract/document_type/property/array.rs (line 706)

Re-verified at head f574f8e (test module 706–842 still exercises only Integer, Number, String, ByteArray, Identifier). ArrayItemType has seven variants; Boolean and Date are uncovered even though Date has dedicated conversion behavior in this file (timestamp vs. ISO-string handling), making it the highest-risk variant for a silent wire-shape regression. Add JSON and Value wire-shape assertions for both variants so the variant matrix introduced by this PR is complete.

suggestion: BLS public-key `visit_seq` collects unbounded input before rejecting it

packages/rs-dpp/src/serialization/dashcore/bls_pubkey.rs (line 151)

Re-verified at head f574f8e (visitor body unchanged). The new BLS public-key serde wrapper accepts byte sequences for JSON/Value round-trips, but visit_seq pushes every element into a Vec and only checks the exact 48-byte (COMPRESSED_G1_LEN) length inside from_compressed_g1_bytes(&bytes) after the sequence ends. A malformed payload with a very large array in a public-key slot forces unnecessary allocation and parsing before the deserializer rejects it. Currently reached only from trusted Dash Core validator data, but the with = "..." pattern is designed for reuse and the failure mode amplifies as soon as another type reuses this module on a less-trusted ingest path. Cap the loop at COMPRESSED_G1_LEN + 1 and error on overflow so the 48-byte structural promise is enforced inside the visitor.

    fn visit_seq<A: serde::de::SeqAccess<'de>>(self, mut seq: A) -> Result<Self::Value, A::Error> {
        let mut bytes = Vec::with_capacity(COMPRESSED_G1_LEN);
        while let Some(b) = seq.next_element::<u8>()? {
            if bytes.len() == COMPRESSED_G1_LEN {
                return Err(serde::de::Error::invalid_length(
                    COMPRESSED_G1_LEN + 1,
                    &"exactly 48 bytes for a compressed G1 BLS public key",
                ));

Code Review

All 9 prior findings re-validated as STILL VALID against head 24ade51. The latest delta f574f8e..24ade51 is a pure refactor removing from_*_validated aliases on DataContract in favor of the from_*(value, bool, &pv) API; it does not touch any of the prior-flagged code paths. One new in-scope finding from codex-general: the unification plan doc still describes the now-deleted _validated helpers and the opposite (no-validation) serde default, contradicting the executable API at conversion/serde/mod.rs:74-79 and the (just-removed) helpers. Review action is REQUEST_CHANGES because prior-1 (committed local infra/SSH runbook) and prior-2/-3 (wasm-dpp2 TS type vs Rust $type discriminator mismatch) remain blocking.

blocking: Committed local runbook exposes live validator infrastructure details

docs/v12-upgrade-boundary-risks.md (line 119)

This section is explicitly labeled local only — contains infra details, do not commit, but it is checked into the PR at 24ade51 unchanged. It publishes a live testnet HPMN validator hostname/IP (hp-masternode-8 = 68.67.122.8, ansible_user ubuntu), a second mainnet-synced host IP (54.185.219.212), the operator SSH key path (~/.ssh/evo-app-deploy.rsa), and concrete ssh/scp invocations. This is operator-sensitive reconnaissance material that is unrelated to the JSON/Value conversion work this PR is about. Remove the entire ## Runbook (local only ...) section before merge and treat the already-pushed host/key details as exposed: rotate evo-app-deploy.rsa and audit access on the named hosts.

Verified at head: the typescript_custom_section declares AssetLockProofObject / AssetLockProofJSON with a plain type discriminator and the doc comment claims rs-dpp uses #[serde(tag = "type")]. The rs-dpp enum at packages/rs-dpp/src/identity/state_transition/asset_lock_proof/mod.rs:37-49 actually uses #[serde(tag = "$type", rename_all = "camelCase")] for both Serialize and RawAssetLockProof Deserialize. JS callers following these public typings will construct objects rs-dpp rejects on from_object / fromJSON (asset-lock proofs feed identity create / topup flows) and will read undefined when branching on obj.type after a Rust→JS round trip. Align the TS declarations and surrounding comments with the executable $type wire shape.

Same discriminator mismatch beyond AssetLockProof.

The same stale plain-type pattern remains in wasm-dpp2 typescript_custom_section blocks for VotePoll, ResourceVoteChoice, ContestedDocumentVotePollWinnerInfo (voting/winner_info.rs), AddressWitness (shielded/address_witness.rs), and TokenEvent (group/token_event.rs). Fee-strategy steps drive which input/output absorbs the transaction fee; rejecting all steps because the discriminator key is wrong silently changes accounting at the JS boundary.

suggestion: C/Swift data-contract JSON no longer pins the SDK protocol version

packages/rs-sdk-ffi/src/data_contract/queries/fetch_with_serialization.rs (line 110)

Verified at head: this FFI path now calls serde_json::to_value(&contract) (line 111). DataContract's manual Serialize impl in packages/rs-dpp/src/data_contract/conversion/serde/mod.rs:48-60 resolves the platform version via PlatformVersion::get_version_or_current_or_latest(None) — process-global state with a fallback to the latest known platform version — rather than the version pinned on the SDK handle the caller passed in (wrapper.sdk). In the same FFI result the bincode serialized_data is still produced through SDK-version-aware paths, so a divergence between json_string and serialized_data for the same contract is reachable whenever the active global differs from wrapper.sdk.version(). The same regression is in packages/rs-sdk-ffi/src/data_contract/queries/fetch_json.rs:54. Build DataContractInSerializationFormat with wrapper.sdk.version() and serialize that explicitly across the FFI boundary.

suggestion: Lenient update-transition constructor no longer accepts legacy `identityContractNonce`

Verified at head: the constructor pre-fills $formatVersion, userFeeIncrease, signaturePublicKeyId, and signature before strict DataContractUpdateTransition::from_object(raw) (lines 71-76), but it does not alias the previous JS public field identityContractNonce to the canonical serde field $identity-contract-nonce. This PR also rewrites the existing JS fixture from identityContractNonce to $identity-contract-nonce, so existing callers built against the old constructor shape now fail with a strict missing-field error. The nonce is replay-protection material for data-contract updates, so this is a breaking JS API rename for wallets/services. Either alias the legacy key into the canonical key in this Value::Map normalization step (keep requiring a real nonce — do not default to zero), or document the field rename as a public migration in the PR notes.

suggestion: TokenPricingSchedule JSON emits u64 prices as unsafe JS numbers

packages/rs-dpp/src/tokens/token_pricing_schedule.rs (line 28)

Verified at head: TokenPricingSchedule derives plain Serialize/Deserialize (line 28) and its JsonConvertible / ValueConvertible impls (lines 48, 51) do not use json_safe_fields or any equivalent large-integer wrapper. SinglePrice(Credits) and SetPrices(BTreeMap<TokenAmount, Credits>) therefore serialize u64 credit and token amounts as raw JSON numbers. Values above Number.MAX_SAFE_INTEGER (2^53) are silently rounded by JavaScript SDK/wasm callers that go through any toJSON() path — a financial-amount truncation on a type that is specifically about authoritative token pricing, in the same conversion sweep this PR introduces. Apply the safe-integer JSON convention used elsewhere in the PR to both variants.

suggestion: TokenDistributionInfo conversion tests pin only the PreProgrammed variant

packages/rs-dpp/src/data_contract/associated_token/token_distribution_key.rs (line 322)

Boolean and Date are uncovered in the canonical round-trip tests, even though Date has dedicated conversion behavior in this file (e.g. lines 168, 229, 279). Add JSON and Value wire-shape assertions for Boolean and Date so a regression in their encoding (e.g. ms-since-epoch as integer vs. string) is caught at unit-test time rather than at runtime in document validation.

suggestion: Unification plan still documents the removed `_validated` API and the wrong serde default

docs/json-value-unification-plan.md (line 840)

Verified at head: this section still says canonical serde_json::from_value::<DataContract>(...) is the no-validation default (lines 840, 853), that the trust-boundary API is from_json_validated(json, &pv) / from_value_validated(value, &pv) with no bool param (line 841, 849), and that from_*_versioned(_, full_validation, _) was deleted entirely (line 843). The latest delta in this PR (commit 24ade51) removes the _validated helpers and routes everything through from_*(value, true, &pv), and the prior commit 6e5d568 restored validate-by-default in conversion/serde/mod.rs:74-79 (hardcoded true) with a comment explicitly pointing readers to from_json/from_value(_, false, _) for the no-validation path. The plan now contradicts the executable API in every direction (default behavior, helper name, bool param). Since the PR description asks reviewers to read this plan for architectural intent, update §10 to reflect the validate-by-default default and the single from_*(value, full_validation, &pv) surface.

Code Review

Incremental + cumulative review against d33f72f. The latest delta (24ade51..d33f72f) is a pure refactor that hoists a Content-safe u128 serde helper into rs-dpp's serialization::json::safe_integer module — no new defect introduced. All 10 coordinator-supplied prior findings re-verify as STILL VALID against this head; none are FIXED, OUTDATED, or INTENTIONALLY DEFERRED. Codex additionally surfaces 4 valid new wasm-dpp2 TypeScript-declaration discriminator mismatches (Voting, AddressWitness, TokenEvent, GroupActionEvent) of the same class as prior-2 / prior-3, consolidated into one new blocking finding to stay within the 10-item budget. Net: 4 blocking + 6 suggestion findings; review_action = REQUEST_CHANGES because in-scope blocking issues remain.

blocking: Committed local runbook exposes live validator infrastructure

docs/v12-upgrade-boundary-risks.md (line 119)

STILL VALID at d33f72f. The section's own header is Runbook (local only — contains infra details, do not commit), yet it is checked in. It publishes a live testnet HPMN validator (hp-masternode-8 = 68.67.122.8, ansible_user ubuntu, explicitly flagged as a live validator), a second mainnet-synced host IP (54.185.219.212), the operator SSH key path (~/.ssh/evo-app-deploy.rsa), and concrete ssh -i ~/.ssh/evo-app-deploy.rsa ubuntu@<host> / scp invocations. Publishing a live validator hostname/IP along with the operator account name and the path of the operator's private key materially lowers attacker effort against that node and contradicts the file's own warning. Remove the section from the PR (or replace it with an instructions-only, host-redacted summary); the operational details belong in a private operations doc, not a public-repo docs/ tree.

blocking: Additional wasm-dpp2 TS surfaces use `type`/`kind` while runtime emits `$type`/`$kind`

packages/wasm-dpp2/src/voting/vote_poll.rs (line 22)

Same root cause as the AssetLockProof and FeeStrategyStep findings — surfaced cumulatively across wasm-dpp2 by this PR's audit pass. Four additional TypeScript declaration blocks still advertise a plain discriminator key while the rs-dpp serializers/deserializers emit and require the $-prefixed key:

• packages/wasm-dpp2/src/voting/vote_poll.rs:38,50 declares type: "contestedDocumentResourceVotePoll", but packages/rs-dpp/src/voting/vote_polls/mod.rs:29 is #[serde(tag = "$type", rename_all = "camelCase")].
• packages/wasm-dpp2/src/shielded/address_witness.rs:17,25,39,47 declares type: "p2pkh" | "p2sh", but packages/rs-dpp/src/address_funds/witness.rs:32 is #[serde(tag = "$type")].
• packages/wasm-dpp2/src/group/token_event.rs:33,42 declares type: string, but packages/rs-dpp/src/tokens/token_event.rs:194-271 emits every variant as serialize_entry("$type", ...) and :329,352 only accepts $type (the in-file comment at :67 confirms the convention).
• packages/wasm-dpp2/src/group/action_event.rs:16,21 declares kind: "tokenEvent", but packages/rs-dpp/src/group/action_event.rs:25 is #[serde(tag = "$kind", rename_all = "camelCase")]. The doubly-tagged GroupActionEvent compounds the issue because its kind mismatch sits on top of the TokenEvent type mismatch.

All four are public TypeScript surfaces; consumers following them either fail deserialization on rs-dpp ingest or get values that don't match the declared shape. Update each typescript_custom_section to use $type (and $kind for GroupActionEvent), matching the convention already followed elsewhere in wasm-dpp2.

suggestion: BLS public-key `visit_seq` collects unbounded input before rejecting it

packages/rs-dpp/src/serialization/dashcore/bls_pubkey.rs (line 151)

STILL VALID at d33f72f. visit_seq allocates with capacity 48 and then while let Some(b) = seq.next_element::<u8>()? { bytes.push(b); }, only enforcing the 48-byte requirement after the sequence ends inside from_compressed_g1_bytes. A hostile JSON or platform_value payload with a multi-megabyte byte sequence forces proportional allocation/parsing on every BLS-pubkey deserialize path (validator-set/state-transition ingest, wasm input, FFI JSON) before being rejected. Cap the loop at 48 elements and error out on the 49th — pure DoS hardening with no consensus impact.

    fn visit_seq<A: serde::de::SeqAccess<'de>>(self, mut seq: A) -> Result<Self::Value, A::Error> {

suggestion: Unification plan still documents the removed `_validated` API and the wrong serde default

docs/json-value-unification-plan.md (line 840)

STILL VALID at d33f72f. This section presents the final shape of the DataContract conversion API as: canonical serde_json::from_value::<DataContract>(...) = no validation (line 840), opt-in DataContract::from_json_validated(json, &pv) / from_value_validated(value, &pv) with no bool param (line 841), and 'Validation default flipped to no-validation' (line 853). All three claims are now false. Commit 6e5d5683d9 restored validate-by-default on Deserialize for DataContract, and 24ade51d34 dropped the _validated aliases in favor of from_json(value, full_validation: bool, &pv) / from_value(value, full_validation: bool, &pv) (verified at packages/rs-dpp/src/data_contract/conversion/json/mod.rs:11). The plan now misdocuments both the validation default and the public API surface in a load-bearing area — update it to match the as-shipped behavior so future readers/contributors don't follow the obsolete plan.

suggestion: TokenPricingSchedule JSON emits u64 prices as unsafe JS numbers

packages/rs-dpp/src/tokens/token_pricing_schedule.rs (line 28)

STILL VALID at d33f72f. TokenPricingSchedule derives plain Serialize/Deserialize, and its JsonConvertible / ValueConvertible impls are blanket no-ops. SinglePrice(Credits) and SetPrices(BTreeMap<TokenAmount, Credits>) both wrap u64, so any price above Number.MAX_SAFE_INTEGER round-trips through canonical JSON as a JS Number and silently loses precision in wasm-dpp2 consumers — exactly the JS-safety gap this PR closes elsewhere via json_safe_u64. Token pricing sits on the contract-author → end-user trust boundary; either apply json_safe_u64 via #[serde(with = ...)] on the variants/map values or document explicitly why this type is exempt and pin the expected wire shape in tests.

suggestion: C/Swift data-contract JSON no longer pins the SDK protocol version

packages/rs-sdk-ffi/src/data_contract/queries/fetch_with_serialization.rs (line 110)

STILL VALID at d33f72f. This FFI path calls serde_json::to_value(&contract). After the unification work DataContract's manual Serialize resolves the platform version internally via PlatformVersion::get_version_or_current_or_latest, so the JSON shape returned to C/Swift depends on process-global current/latest state rather than the SDK/network protocol version the caller is operating against. For a mobile SDK whose JSON output is expected to be reproducible across protocol-version rolls, this couples FFI output to an unrelated global. Route through an explicit version-pinned serializer (e.g. to_validating_json(&pv) or whichever versioned conversion the trait still exposes), using the SDK's configured platform version.

suggestion: Lenient update-transition constructor does not accept legacy `identityContractNonce`

packages/wasm-dpp/src/data_contract/state_transition/data_contract_update_transition/mod.rs (line 52)

STILL VALID at d33f72f. The constructor pre-fills $formatVersion, userFeeIncrease, signaturePublicKeyId, and signature and then calls strict DataContractUpdateTransition::from_object(raw). The V0 transition's identity-contract-nonce field is serde(rename = "$identity-contract-nonce") (packages/rs-dpp/src/state_transition/state_transitions/contract/data_contract_update_transition/v0/mod.rs:31-36), but the lenient constructor does not alias the previous JS public name identityContractNonce to that canonical key. Legacy JS clients constructing the transition with the old field name will silently land with the nonce missing/defaulted on the strict path — and the nonce is the replay-protection primitive. Either alias the legacy key before strict deserialization or detect-and-error so callers update.

suggestion: Canonical conversion tests miss enum variants (ArrayItemType: Boolean/Date; TokenDistributionInfo: Perpetual)

packages/rs-dpp/src/data_contract/document_type/property/array.rs (line 706)

STILL VALID at d33f72f. Two adjacent canonical-conversion test modules don't pin every variant of their enum:

• packages/rs-dpp/src/data_contract/document_type/property/array.rs:706-842 covers Integer, Number, String, ByteArray, Identifier — but ArrayItemType also has Boolean and Date (defined at lines 15-16). A wire-shape regression in those two variants (internal-tag rename, accidental adjacent tagging) would not be caught.
• packages/rs-dpp/src/data_contract/associated_token/token_distribution_key.rs:322-389 only fixtures TokenDistributionInfo::PreProgrammed, leaving Perpetual and the TokenDistributionTypeWithResolvedRecipient branches unpinned for both JSON and Value round-trip / wire-shape assertions.

Add a fixture + round-trip + literal wire-shape assertion for each missing variant, following the {"$type": ...} pattern already used in these modules. This PR's stated goal is to pin canonical wire shapes; finishing the variant coverage is required for that pinning to hold.

Code Review

Verified against head 603b10c. One new latest-delta blocking issue survives verification in the Swift token wrappers; the unresolved carried-forward issues are still concentrated in wasm TypeScript discriminator declarations and canonical JSON/Value conversion edge cases. CodeRabbit supplied no inline findings, and prior findings 1 and 6 are resolved because the referenced docs were removed.

Reviewed commit: 603b10c6

Source: reviewers: opus general/security-auditor/ffi-engineer failed (extra-usage quota, reset Jul 10 8am America/Chicago); gpt-5.5 general/security-auditor/ffi-engineer completed. Verifier: opus failed same quota; gpt-5.5 completed. Specialists: security-auditor, ffi-engineer.

Result: 4 blocking, 5 suggestion(s).

New Findings In Latest Delta

blocking: Keep the token signer alive for the whole FFI callback

packages/swift-sdk/Sources/SwiftDashSDK/PlatformWallet/Tokens/TokenActions.swift (lines 108-127)

This latest-delta wrapper captures only signerHandle for the actual platform_wallet_token_transfer call and uses _ = signer before the FFI call starts. KeychainSigner registers its Rust callback context with Unmanaged.passUnretained(self), so Rust later dereferences a non-owning Swift object through the signer vtable. A bare _ = signer is the last use of the object in the detached task and can be optimized/released before the synchronous Rust signing callback completes; nearby wallet wrappers now use withExtendedLifetime(signer) for this exact reason. tokenBurn has the same pattern at lines 170-192. Wrap the full marshalling and FFI call in withExtendedLifetime(signer) so short-lived signer arguments cannot be deallocated while Rust is signing.

Carried-Forward Prior Findings

blocking: AssetLockProof declarations still advertise `type` instead of `$type`

packages/wasm-dpp2/src/asset_lock_proof/proof.rs (lines 23-37)

Carried forward from prior-2. The TypeScript custom section says AssetLockProofObject and AssetLockProofJSON are discriminated by type, but the rs-dpp enum derives and deserializes with #[serde(tag = "$type")]. Because this wrapper now delegates through the canonical inner conversion path, JS payloads that satisfy the generated TypeScript shape fail at the wasm/Rust boundary with a missing $type, and runtime toObject()/toJSON() output does not satisfy the published declarations.

blocking: FeeStrategyStep declarations use `type` while deserialization requires `$type`

packages/wasm-dpp2/src/platform_address/fee_strategy.rs (lines 13-30)

Carried forward from prior-3. FeeStrategyStepObject and FeeStrategyStepJSON document { type, index }, and the wrapper comment repeats that shape. The wrapped AddressFundsFeeStrategyStep serializer emits $type, and its custom deserializer only reads $type, returning missing_field("$type") for the documented object. Wallet code following these declarations can build address-funded transitions that type-check in TypeScript but are rejected by the canonical wasm/Rust conversion.

blocking: Several wasm-dpp2 declarations still use unprefixed discriminators

packages/wasm-dpp2/src/voting/vote_poll.rs (lines 38-50)

Carried forward from prior-4, with the same root cause still present across companion wrappers. VotePollObject/VotePollJSON declare type, but rs-dpp serializes VotePoll with $type; ResourceVoteChoice and ContestedDocumentVotePollWinnerInfo declarations also use type while their manual serializers require $type; AddressWitness declarations use type while the enum is #[serde(tag = "$type")]; and GroupActionEvent/TokenEvent declarations use kind/type while runtime output is $kind/$type. The PR states that discriminated enums use $-prefixed keys, and these public TS sections now contradict the canonical conversion paths they expose, causing TS-valid payloads to fail deserialization and returned objects to violate the generated types.

suggestion: TokenPricingSchedule JSON can still emit unsafe u64 numbers

packages/rs-dpp/src/tokens/token_pricing_schedule.rs (lines 28-51)

Carried forward from prior-7. This PR adds canonical JsonConvertible/ValueConvertible impls for TokenPricingSchedule, but the enum still derives plain serde for SinglePrice(Credits) and SetPrices(BTreeMap<TokenAmount, Credits>). Both aliases are u64, and the new tests pin JSON numbers such as { "SinglePrice": 1234 } and { "SetPrices": { "5": 50 } }. Values above JavaScript's safe integer range can be rounded by JS consumers, which conflicts with the PR's stated JS-safe large-integer coverage and the explicit escape-hatch comment claiming developers handle this type safely.

suggestion: FFI data-contract JSON no longer uses the SDK protocol version

packages/rs-sdk-ffi/src/data_contract/queries/fetch_with_serialization.rs (lines 110-131)

Carried forward from prior-8. The FFI fetch path returns JSON to C/Swift by calling serde_json::to_value(&contract). DataContract serde intentionally resolves PlatformVersion::get_version_or_current_or_latest(None), but this boundary used to serialize with wrapper.sdk.version(). The JSON shape returned by this SDK API can now depend on process-global/current/latest protocol state rather than the network version used for the proof-verified fetch. Keep the general DataContract serde exception, but route this FFI API through an explicit SDK-versioned serialization path.

suggestion: Reject oversized BLS public-key sequences before allocating them

packages/rs-dpp/src/serialization/dashcore/bls_pubkey.rs (lines 151-157)

Carried forward from prior-5. visit_seq accepts a byte sequence, pushes every element into a Vec, and only then calls from_compressed_g1_bytes, which rejects anything other than 48 bytes. A hostile JSON/Value payload can force allocation and parsing proportional to an arbitrarily large sequence before the fixed-size public key length check runs. Since valid compressed-G1 input is exactly 48 bytes, reject immediately when the 49th byte is seen.

suggestion: Legacy update-transition constructor does not alias `identityContractNonce`

packages/wasm-dpp/src/data_contract/state_transition/data_contract_update_transition/mod.rs (lines 62-76)

Carried forward from prior-9. The legacy wasm constructor preserves lenient JS construction by defaulting $formatVersion, userFeeIncrease, signaturePublicKeyId, and signature, then calls strict DataContractUpdateTransition::from_object(raw). The strict V0 struct now expects the nonce as $identity-contract-nonce, but this compatibility shim does not map the older JS-facing identityContractNonce key. Existing callers using the legacy field name can no longer construct an update transition through this lenient path.

suggestion: Canonical conversion tests still miss changed enum variants

packages/rs-dpp/src/data_contract/document_type/property/array.rs (lines 715-841)

Carried forward from prior-10. The new canonical wire-shape tests for ArrayItemType cover Integer, Number, String, ByteArray, and Identifier but omit Boolean and Date, even though both variants participate in the same $type representation. The related TokenDistributionInfo tests in token_distribution_key.rs only pin PreProgrammed and omit Perpetual. Because this PR's stated goal is comprehensive canonical JSON/Value round-trip coverage, add literal JSON and Value assertions for these variants so discriminator and field-shape regressions are caught.
