…lance to shielded pool) Adds state transition type 21, `ShieldFromIdentity`, which moves credits from a Platform identity's balance directly into the Orchard shielded pool in one identity-signed transition. Today the same result needs two transitions (IdentityCreditTransferToAddresses then Shield), two fees, and a throw-away platform address that links the identity to the shield. The transition is a hybrid of two shipped ones: the funding side is exactly IdentityCreditTransferToAddresses (identity id, identity nonce, TRANSFER key, identity-paid fee path); the pool side is exactly Shield (outputs-only Orchard bundle, FLAGS_OUTPUTS_ONLY proof verification with value_balance = -amount, note inserts, pool total update, shielded compute fee as the fixed add-on). Consensus: - activates at protocol version 14 via SHIELD_FROM_IDENTITY_INITIAL_PROTOCOL_VERSION (is_allowed gate and 14..=LATEST active range); older tables carry inactive rows - fee = metered storage/processing + compute_shielded_verification_fee, paid from the identity through the existing Paid execution event; user_fee_increase applies - ops: UpdateIdentityNonce, RemoveFromIdentityBalance, InsertNote per action, UpdateTotalBalance; no system-credit adjustment (identity balance and pool are both terms of the block conservation equation) - no extra Orchard sighash data: the identity signature covers every bundle field - proof result reuses VerifiedPartialIdentity (post-debit balance), as withdrawals do Clients: rs-sdk ShieldFromIdentity trait on Identity, platform-wallet operation and PlatformWallet wrappers with a new ShieldFromIdentity activity kind (tag 8), FFI entry point platform_wallet_manager_shielded_shield_from_identity and fee kind 3, wasm-dpp2 ShieldFromIdentityTransition wrapper and spec, legacy wasm-dpp arm, and the shielded fees book chapter. Tests: dpp structure/serialization/signable-bytes/JSON tests and builder tests, drive converter tests, and drive-abci tests with real Halo2 proofs covering the rejection matrix, a full block run with credit conservation and exact identity debit, fee increase, prove/verify round trip, and pre-14 rejection.

Bridges the platform_wallet_manager_shielded_shield_from_identity FFI export (type 21, identity balance to shielded pool) to both mobile SDKs, keeping all business logic in Rust. Swift: PlatformWalletManager.shieldedShieldFromIdentity(walletId:shieldedAccount: identityId:amount:identitySigner:) next to shieldedShield, same handle, buffer, and error-mapping patterns; ShieldedFeeKind.shieldFromIdentity = 3; activity kind tag 8 labelled in the example app's activity and storage views. Kotlin: JNI export FundingNative.shieldedShieldFromIdentity, the matching external declaration, PlatformWalletManager.shieldedShieldFromIdentity signing with the manager's Keystore signer handle, ShieldedProver.FeeKind.ShieldFromIdentity(3), and the activity tag 8 label in the example app. Also documents estimator fee kind 3 on the Rust FFI. Verified: cargo check for rs-unified-sdk-jni and platform-wallet-ffi, gradle :sdk:compileDebugKotlin :app:compileDebugKotlin, and build_ios.sh --target sim (FFI slice, xcframework, and SwiftExampleApp with warnings as errors).

…up, pool-read fee) - clippy under -D warnings: drop an unused import in the dpp builder test and import the ShieldFromIdentity variant in the wasm-dpp2 base file - restrict the automatic TRANSFER key lookup to SecurityLevel::CRITICAL, the only level the transition's signing policy accepts, so a non-critical transfer key is skipped instead of failing in sign_external - meter the pool total-balance read: the transformer now folds the GroveDB read cost into the execution context as a precalculated operation, threading block_info and execution_context through, so the identity-paid event charges it - wasm-dpp2 verify_public_key: add the ShieldFromIdentity arm so the JS preflight applies the same purpose, security-level, and enabled checks as native signing - book: the entry-transition section now names all three entry transitions (heading, anchors, and the later fee-flow paragraph) - Kotlin KDoc: cite the Swift counterpart and fix two sentences Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…shielded pool to identity) Adds state transition type 22, `IdentityTopUpFromShieldedPool`, which spends shielded-pool notes to top up an EXISTING Platform identity's balance. It is the reverse of ShieldFromIdentity (type 21) and the identity-output sibling of Unshield: spend mechanics, nullifier replay protection, pool-paid flat fee, and the sighash binding all follow Unshield, with the identity replacing the transparent address as the output. Consensus: - no platform signature: the Orchard proof authorizes the spend, and the target identity id plus the gross amount are committed into the Orchard binding sighash (new identity_top_up_from_shielded_extra_sighash_data helper), so a valid bundle cannot be re-pointed at another identity - activates at protocol version 14 via IDENTITY_TOP_UP_FROM_SHIELDED_POOL_INITIAL_PROTOCOL_VERSION; older validation tables carry inactive rows - fee = compute_shielded_identity_top_up_fee(num_actions), the base shielded minimum plus a flat identity-balance write component priced like Unshield's address write; validated by the shielded minimum-fee gate and carved from the value balance through the existing PaidFromShieldedPool event - stateful checks: pool notes floor, anchor, unspent nullifiers, pool balance, and the identity must already exist (IdentityNotFoundError otherwise) - ops: InsertNullifiers, AddToIdentityBalance(amount - fee), InsertNote per action, UpdateTotalBalance(pool - amount); no system-credit adjustment - proof: strict merged nullifiers plus full identity, returning the existing VerifiedIdentityWithShieldedNullifiers result Clients: dpp builder, rs-sdk IdentityTopUpFromShieldedPool trait, wallet operation and PlatformWallet wrapper with a new IdentityTopUp activity kind (tag 9), wallet FFI platform_wallet_manager_shielded_identity_top_up_from_pool and estimator fee kind 4, wasm-dpp2 wrapper and spec, legacy wasm-dpp arm, Swift shieldedIdentityTopUpFromPool and Kotlin JNI/SDK wrappers, book row. Tests: dpp structure, serialization, JSON and value round trips, builder; drive converter tests; drive-abci tests with real Halo2 spend proofs covering structure and fee-floor rejections, invalid proof, mutated amount, bundle re-pointed at another identity, unknown identity, pre-14 rejection, a full block run asserting credit conservation and the exact identity credit, and a strict prove/verify round trip.

Found two issues in the new wallet top-up flow: its strict proof wait turns successful top-ups into unconfirmed-spend errors, and it never reconciles the balance of a wallet-managed recipient. Both findings concern #4711's additions over #4708; details and suggested corrections are inline.
Validation: all 17 focused DPP tests passed (10 matching identity_top_up_from_shielded_pool and 7 matching state_transition_types, with --all-features --lib --offline). The wallet findings were verified by tracing the proof outcome classification, wait/error handling, persistence, and downstream balance checks; no live transaction or native app build was run.

[P1] Use the affected-state wait for this top-up flow
This helper reaches broadcast_shielded_spend, which calls the strict wait_for_response. However, this PR explicitly classifies IdentityTopUpFromShieldedPool as AffectedState in state_transition_proof_binds_execution. Even a valid proof after a successful top-up therefore becomes ExecutionNotProved, then ShieldedSpendUnconfirmed: the normal success/finalization branch is unreachable, and Swift/Kotlin report an unconfirmed spend while keeping reservations and scheduling redrive. Use a type-22-specific affected-state wait, as the new standalone SDK method already does, while preserving staged broadcast, consensus-rejection handling, and recovery for genuinely ambiguous outcomes.

[P2] Reconcile the managed recipient's balance after topping up
When the recipient belongs to this wallet, the new flow still returns only () and never updates its managed identity or persisted snapshot. Shielded sync reconciles notes/activity but also leaves the identity balance unchanged. After topping up an empty identity, even once note sync confirms the spend, purchase_dpns_name still reads the old managed.balance() and can reject locally with InsufficientIdentityCredits until an explicit identity refresh. Retain the authenticated identity result and proof height, then reconcile and persist managed recipients as top_up_from_addresses does; external recipients should remain supported without adding them to the wallet.
… the lint limit The wasm-dpp2 lint job fails on a 141-character line in the new spec (max-len 140, stylistic max-len 120). Alias the wrapper class inside the round-trip test so all three assertions stay under 120 characters. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…ilable code on ShieldFromIdentity Addresses the Codex review on the wallet integration of ShieldFromIdentity: - PlatformWallet::shielded_shield_from_identity now applies the proven post-debit balance to the managed identity and persists its snapshot, the same pattern transfer_credits_to_addresses_with_external_signer follows. A proof without a balance (None) leaves the identity untouched. - The activity row no longer stores the shielded compute fee floor as the exact fee. The metered part is only known at execution and never returned, and ShieldedActivityEntry::fee is exact (the FFI reports has_fee), so the row now records None until a source of the exact fee exists. - A SigningKeyUnavailable completion from the identity signer is preserved under PlatformWalletError::Sdk via preserve_signer_key_unavailable_or instead of being stringified into ShieldedBuildError, and map_spend_result restores code 31 (ErrorSigningKeyUnavailable) for that shape so hosts keep their key-repair routing. Unit tests cover both layers, including the mid-string marker that must not be promoted. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
…laude/identity-topup-from-shielded-pool
…'s own balance proof wait_for_affected_state converts the proof generically, so the wallet accepted any successful result (or a VerifiedPartialIdentity for a different identity, or one without a balance) as confirmation of the shield. Mirror the SDK's ShieldFromIdentity check: only a VerifiedPartialIdentity whose id is the funding identity and which carries a balance confirms the activity; every other result leaves the row pending and reports ShieldedSpendUnconfirmed. The balance is therefore always present on success, so the operation, the PlatformWallet entry points, and the FFI now return Credits instead of Option<Credits>; the FFI signature is unchanged and the Swift, Kotlin, and JNI docs no longer describe a zero-balance success.

…laude/identity-topup-from-shielded-pool
…ntity proofs, nonce-reconciled wallet failures Addresses the Codex security rereview of ShieldFromIdentity. Consensus (drive-abci, drive, dpp): - A failed Orchard proof is no longer a free rejection that leaves the identity nonce and balance reusable. Like ShieldFromAssetLock, the proof is now verified inside the transition's own transform, and a failure returns a BumpIdentityNonceAction with the consensus error: the transition executes as a paid failure that consumes the nonce and charges the versioned shielded_proof_verification_failure penalty on top of the processing metered so far. CheckTx passes its proof-admission budget into the same transform and still rejects on failure without charging. - The stateless admission floor is raised from the compute fee to a conservative complete fee: compute_shielded_identity_balance_write_fee (compute_minimum_shielded_fee plus a flat 222-byte identity-write allowance at the storage rate), so an identity that could not pay the complete fee is refused before proof verification. The FFI estimator kind 3 reports the same floor. Wallet: - Unauthenticated failure verdicts (a rejected broadcast, a consensus error in the result wait) are reconciled against the identity's proven nonce before the activity row is marked Failed. Only a proof that shows the transition's nonce was never merged allows Failed; otherwise the row stays pending and the caller gets ShieldedSpendUnconfirmed, since an identity shield has no input nullifier and a rebuilt retry would debit the identity again under a fresh nonce. - The balance proof binds neither the transition nor the note, so it no longer confirms the activity row. The row stays pending until the shielded scan observes the note commitments on-chain, like the ambiguous post-broadcast paths. Tests: paid-penalty and admission-floor tests in drive-abci (nonce consumed, exact penalty debited, pool untouched; nothing charged below the floor), the floor formula in dpp, and the nonce-mask reconciliation predicate in the wallet.

…o its measured cost SHIELDED_IDENTITY_BALANCE_WRITE_STORAGE_BYTES was copied from the Unshield address-write constant (222) rather than measured, and its docs described a new-address-style storage write. The identity-side operations of a ShieldFromIdentity (UpdateIdentityNonce and RemoveFromIdentityBalance) replace existing elements and add no storage bytes: their GroveDB-metered cost is 424,400 credits of processing, 15.5 effective bytes at the 27,400 credits/byte storage rate. The constant is now 16, with the same small round-up the other calibrated shielded constants use, and the docs say what it covers. The 2-action floor becomes 114,578,400 credits against a measured real fee of 106,059,160, still conservative. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

…component to its measured cost SHIELDED_IDENTITY_TOP_UP_BALANCE_STORAGE_BYTES was copied from the Unshield address-write constant (222) rather than measured. The top-up's only identity-side operation, AddToIdentityBalance, replaces the existing identity's balance element and adds no storage bytes: its GroveDB-metered cost is 175,280 credits of processing, 6.4 effective bytes at the 27,400 credits/byte storage rate. The constant is now 7, with the same small round-up the other calibrated shielded constants use, so the pool-paid flat fee stops overcharging about 5.9M credits per top-up.

…t replace-only tree work The identity nonce and balance writes add no storage but rewrite their elements and every Merk node on the path to the root: 563 and 320 replaced bytes, 466,760 credits of processing at protocol version 14 (424,400 when batched). Like every other flat shielded component, that variable tree work is folded into one flat effective-byte figure at the storage rate instead of being modelled per replaced byte. 466,760 credits is 17.0 effective bytes; the constant is 20, leaving headroom for the path growing by about a node per doubling of the identity count.

Like every other flat shielded component, that variable tree work is folded into one flat effective-byte figure at the storage rate instead of being modelled per replaced byte. 175,320 credits is 6.4 effective bytes; the constant is 8, leaving headroom for the path growing by about a node per doubling of the identity count.

The previous merge commit was pushed with an unresolved conflict block in the shielded constants (both branches rewrote adjacent constant docs). This restores the file: the ShieldFromIdentity component from the base branch (20) followed by the top-up component (8), no markers. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

#4708 (ShieldFromIdentity) was squash-merged into v4.2-dev as 8c35ed1 together with #4715's hardening, so the original #4708 commits carried by this branch now conflict textually with the squash. The merge tree is the pure top-up delta (this branch relative to the last #4708 tip it merged, ead503c) re-applied onto the new v4.2-dev with a three-way apply, which landed without conflicts, and verified: fmt, targeted dpp/drive/drive-abci/ wallet/FFI tests, clippy at CI settings, wasm32, verify-only drive and the Kotlin compile all pass.

…t the proven balance Addresses the review of IdentityTopUpFromShieldedPool: - The wallet's shared spend path uses the strict result wait, which rejects snapshot outcomes, while the verifier classified type 22 as a snapshot; every successful top-up therefore surfaced as ShieldedSpendUnconfirmed with its notes left pending. Type 22 is now proof-binding like the other nullifier-spend families: its spent nullifiers identify this exact transition and, unlike identity-create, no fallback action spends them on a failed top-up. The drive-abci prove/verify test asserts the executed outcome. - The shared spend helper returns the proven result, the operation extracts the credited identity's proof-attested balance, and the wallet applies and persists it for a managed identity (adding the requested amount locally would be wrong when the fee or a negative balance absorbs part of the top-up). The FFI signature is unchanged. - The top-up FFI export now runs under catch_spend_panic like the shield-to-recipient export, so a proving panic cannot unwind across the C ABI. - The durable-recovery classifier recognises type 22 as a nullifier-funded spend, so a damaged ancillary field on its redrive row no longer fails store rehydration. - The wasm wrapper's identityId setter is removed: the field is committed by the Orchard binding signature and the wrapper cannot re-sign. - The fee guide lists the top-up in the pool-paid fee-flow and flat-component sections.

…y top-up The top-up applies the identity's proof-attested absolute balance to a managed identity. Two top-ups, or a top-up and a shield-from-identity debit, whose result waits complete out of execution order would let the older balance overwrite the newer one. The top-up now holds the wallet's single-flight shield guard across build, broadcast, wait and reconcile, the same guard the identity debit already holds, so those writes land in execution order.

…rdingly A spent nullifier is stored as an empty item shared by every spend family, so its presence cannot tell one top-up apart from a competing spend of the same notes that credits another identity, and the credited identity's balance is a snapshot at the proof's block. Classifying type 22 as execution-proving let a proof for a top-up that never executed verify as ExecutionProved once a competing spend consumed its nullifiers. The verifier now returns AffectedState for the family, and a drive-abci test reproduces the competing spend: the losing transition's proof verifies, is classified as a snapshot, and shows its identity never credited. The wallet's shared spend helper takes a wait mode: the proof-binding families keep the strict wait, and the top-up uses the affected-state wait like the shield, shield-from-identity and identity-create paths, preserving the staged broadcast, consensus-rejection classification and redrive arming. The snapshot still proves the reserved notes are consumed and authenticates the credited identity's balance, which the wallet applies as the balance at that block.

… on spent nullifiers The affected-state snapshot cannot distinguish this top-up from a competing spend of the same notes, but only this wallet's spending key can author one and the notes were reserved locally, so the row is confirmed once the nullifiers are proven consumed, matching the transfer, unshield and withdrawal paths.

Do not report an affected-state match as executed.
identity_top_up_from_pool uses SpendResultWait::AffectedState. A competing spend can therefore return Ok with the reserved notes spent and the target identity's unchanged snapshot. The success branch records ShieldedActivityStatus::Confirmed, finalizes the notes, and returns success even though the type 22 top-up did not execute.
Keep the activity Pending or mark it Unknown until a transition-bound receipt proves execution.

There is no way to move value from the shielded pool back onto an existing identity in one step.
Unshieldcredits a transparent platform address, so a user who wants to fund an identity from private notes has to unshield to an address and then runIdentityTopUpFromAddresses: two transitions, two fees, and a transparent hop that links the pool spend to the identity.This PR adds
IdentityTopUpFromShieldedPool(state transition type 22): spend shielded notes and credit an existing identity's balance directly. Activates at protocol version 14.What was done?
The transition is
Unshieldwith the identity as the output (the reverse direction ofShieldFromIdentityin #4708):Unshield: Orchard spend bundle (actions,anchor,proof,binding_signature), nullifier replay protection, pool notes floor, anchor and pool-balance checks,FLAGS_SPENDS_AND_OUTPUTSproof verification withvalue_balance = top_up_amount.identity_idand the grosstop_up_amountare committed into the Orchard binding sighash through a newidentity_top_up_from_shielded_extra_sighash_datahelper (identity_id (32) || amount (u64 LE), the same shape as the unshield helper), so a valid bundle cannot be re-pointed at another identity. Consensus and the client builder call the same function.compute_shielded_identity_top_up_fee(num_actions)= base shielded minimum plus a flat identity-balance write component (SHIELDED_IDENTITY_TOP_UP_BALANCE_STORAGE_BYTES = 8, built likeUnshield's address-write component: the balance rewrite's replace-only Merk path work, measured at 320 replaced bytes and 175,320 credits of processing, folded into a flat effective-byte figure with headroom like the other shielded components). Enforced by the existing shielded minimum-fee validation (newShieldedMinFeeKind::IdentityTopUp) and carved from the value balance through the existingPaidFromShieldedPoolexecution event. No new fee constants in the version tables.IdentityNotFoundError(a top-up must never create a keyless identity).InsertNullifiers,AddToIdentityBalance(amount - fee),InsertNoteper action,UpdateTotalBalance(pool - amount). The pool and identity balances are both terms of the block conservation equation, so noAddToSystemCredits(the same rule asUnshieldandIdentityCreateFromShieldedPool).IdentityCreateFromShieldedPoolprove/verify shape), returning the existingVerifiedIdentityWithShieldedNullifiersresult. No new proof-result variant. The verifier classifies type 22 as affected state: a spent nullifier is an empty item shared by every spend family, so it cannot tell this top-up apart from a competing spend of the same notes that credits another identity, and the identity's balance is a snapshot at the proof's block (a drive-abci test executes a competing top-up over the same note and checks the loser's proof verifies only as a snapshot). The wallet therefore uses the affected-state wait for this family, keeping the staged broadcast, consensus-rejection classification and redrive arming; it applies the credited identity's proof-attested balance to a managed identity as the balance at that block, since the local balance cannot be derived by adding the requested amount (the fee, or a negative balance, absorbs part of it).IDENTITY_TOP_UP_FROM_SHIELDED_POOL_INITIAL_PROTOCOL_VERSION = 14; inactive rows in validation tables v1 to v9, active in v10.Files by layer:
state_transitions/shielded/identity_top_up_from_shielded_pool_transition/,StateTransitionType::IdentityTopUpFromShieldedPool = 22, every dispatch site instate_transition/mod.rs, sighash helper, fee function and constant, client buildershielded/builder/identity_top_up_from_shielded_pool.rs.is_allowedgate.IdentityTopUpFromShieldedPooltrait; wallet operationidentity_top_up_from_pool+PlatformWallet::shielded_identity_top_up_from_poolwithShieldedFeeKind::IdentityTopUpand activity kindIdentityTopUp { identity_id }(tag 9); wallet FFIplatform_wallet_manager_shielded_identity_top_up_from_pool(panic-guarded like the shield-to-recipient export) and estimator kind 4; wasm-dpp2IdentityTopUpFromShieldedPoolTransitionwrapper (identityIdis read-only: it is committed by the Orchard binding signature), base groupings and spec; legacy wasm-dpp arm; SwiftshieldedIdentityTopUpFromPool(+ShieldedFeeKind.identityTopUpFromPool, tag 9 labels); Kotlin JNIshieldedIdentityTopUpFromPool,PlatformWalletManager.shieldedIdentityTopUpFromPool,FeeKind.IdentityTopUpFromPool, tag 9 label.fees/shielded-fees.mdtable row, pool-paid fee-flow entry and flat-component bullet.Not included: example-app send-flow UI for the new transition in either mobile app.
Known limitation, deliberate, follow-up planned. The wallet confirms the activity row once the affected-state proof shows the reserved notes' nullifiers consumed. That proof cannot distinguish this top-up from a competing spend of the same notes by the same spending key, so a second device on the same seed could show a confirmed row for a top-up its sibling displaced. This matches how the transfer, unshield and withdrawal paths confirm today and was chosen for UX over a pending row. The fix is a transition-bound receipt in the protocol (for example the Orchard sighash stored in the nullifier entry, which the verifier recomputes and compares), which would make all four nullifier-spend families execution-proving; that is a separate PV14 change.
How Has This Been Tested?
cargo test -p dpp --all-features --lib -- identity_top_up_from_shielded_pool state_transition_types: 17 tests (structure rejections, serialization, JSON and value wire shapes, umbrella round trip, builder insufficient-funds, type enum).cargo test -p drive --all-features --lib -- identity_top_up_from_shielded_pool: 3 converter tests (op order and net credit, no system-credit adjustment, fee above amount is an error).cargo test -p drive-abci --lib -- identity_top_up_from_shielded_pool: 10 tests with real Halo2 spend proofs: zero amount, amount below the flat fee (InsufficientShieldedFeeError), invalid proof, unknown identity with a valid proof (IdentityNotFoundError), mutated amount, valid bundle re-pointed at another identity (rejected, other identity untouched), pre-14 rejection, a full block pipeline run asserting sum-tree conservation, unchanged total platform credits, pool loss of exactly the gross amount, identity credit of exactlyamount - fee, and the exact booked fee, plus a strict prove/verify round trip returning the identity and all nullifiers spent as an affected-state snapshot, and a competing-spend case where another top-up over the same note executes first and the loser's proof still verifies, only as a snapshot showing its identity uncredited.

Consensus: new state transition type 22 and activation gate at protocol version 14; every version table gains an
identity_top_up_from_shielded_poolrow; pre-14 nodes reject the transition at decode time. Wallet FFI: new activity kind tag 9 and estimator fee kind 4.Checklist:
