fix(platform-wallet): estimate shielded fees at the network's active protocol version - #4470
Conversation
…protocol version platform_wallet_shielded_estimate_fee pinned PlatformVersion::latest(), so once a client ships the protocol-14 fee rebalance its fee preview under-quotes any network still running protocol 13 (114.14M vs the 162.85M credits the consensus gate actually validates for a 2-action transfer) — while the shielded builders correctly carve fees at the manager's network-tracked sdk.version(). Take the manager handle and resolve the version through the manager's SDK, exactly like the builders do. An unknown handle is a hard ErrorInvalidHandle — a versionless fallback would silently mis-quote. Thread the handle through the Swift binding (estimateShieldedFee becomes an instance method), the JNI export, and the Kotlin wrapper (moved from the process-global ShieldedProver onto PlatformWalletManager, matching the other manager-handle entry points), and update both example apps' send/fund screens. Pin the estimator's formula table on both sides of the boundary: protocol 13 (162,851,200 / 168,934,000 / 275,191,200 credits at 2 actions) and protocol 14 (114,140,000 / 120,222,800 / 226,480,000). Raised by review on #4467; stacks on feat/shielded-fee-rebalance. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Preliminary review — Codex only
The estimator now derives fees from the manager SDK version, but it changes two released native ABIs in place, allowing mismatched published wrappers and libraries to invoke the same symbols with shifted arguments. The formula tests also bypass the successful handle-to-version path, leaving the central behavior of this fix unprotected.

- [BLOCKING] packages/rs-platform-wallet-ffi/src/shielded_send.rs:208-213: Preserve the released estimator ABI when adding manager context
`platform_wallet_shielded_estimate_fee` was released in v4.0.0 with `(kind, num_actions, out_fee)`, but this changes the same exported symbol to `(handle, kind, num_actions, out_fee)`. A new wrapper loading an older library therefore passes `num_actions` where the old function expects `out_fee`, potentially writing through a small integer address; an older wrapper loading the new library similarly supplies shifted or undefined arguments. The JNI export at `packages/rs-unified-sdk-jni/src/funding.rs:98-104` has the same problem: its released v4.1.0 short JNI symbol is unchanged while a `jlong` is inserted into the descriptor, so the JVM can resolve the symbol despite incompatible arguments. Keep the released C and JNI entry points intact, add manager-aware exports under new names, and route the updated Swift and Kotlin APIs through those new exports.
- [SUGGESTION] packages/rs-platform-wallet-ffi/src/shielded_send.rs:1665-1671: Test version resolution through the public FFI estimator
The protocol-13 and protocol-14 tests call `shielded_fee_formula` directly with explicit versions. They never create a manager or exercise the successful `platform_wallet_shielded_estimate_fee` path that resolves `manager.sdk().version()`. Consequently, replacing the lookup with `PlatformVersion::latest()` would still leave every added test passing. Create live managers backed by SDKs pinned to protocols 13 and 14, call the exported estimator through each handle, and assert the corresponding fee values.
… resolution end-to-end Exercise platform_wallet_shielded_estimate_fee through live mock-SDK managers pinned to protocol 13 and protocol 14, asserting the two rebalance-boundary transfer fees through the same exported entry point — a latest() regression now fails the protocol-13 half.

The manager-handle lookup and new end-to-end test correctly pin protocol-13 and protocol-14 behavior, and the Swift negative-action crash is fixed. The released C/JNI estimator symbols still have incompatible signatures, while the example applications can retain estimates calculated before the asynchronous protocol-version ratchet completes.

- [SUGGESTION] packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Core/Views/SendTransactionView.swift:531-537: Recompute cached fees after the SDK protocol version ratchets
`AppState` publishes a newly created SDK before its detached `refreshProtocolVersion()` finishes. An unpinned SDK initially uses protocol 11 on mainnet or protocol 12 on the other networks, so this method can cache the older 162,851,200-credit transfer fee before a protocol-14 network ratchets the shared SDK to the 114,140,000-credit fee used by builders. `resolveShieldedFees()` runs only on appearance and its nonempty guard prevents replacement, even though `platformState.platformProtocolVersion` publishes refresh completion. The Kotlin producers have the same stale-cache path because `SendTransactionScreen.kt:292-309` keys only on `flow` and `manager`, while `ShieldedFundScreen.kt:82-88` keys only on `manager`. Observe `platformProtocolVersion` in all three screens and replace the estimates whenever it changes so previews remain aligned with the version builders read at submission time.

- [BLOCKING] packages/rs-platform-wallet-ffi/src/shielded_send.rs:208-213: Preserve the released estimator ABI when adding manager context
(existing thread: https://github.com/dashpay/platform/pull/4470#discussion_r3845329252)
`platform_wallet_shielded_estimate_fee` shipped in v4.0.0 as `(kind, num_actions, out_fee)`, but the same exported C symbol now expects `(handle, kind, num_actions, out_fee)`. A new caller loading the old library supplies `num_actions` where the library expects `out_fee`, allowing the old implementation to write through a small integer address; the inverse mismatch also invokes the new implementation with shifted and missing arguments. The crate explicitly produces `staticlib` and `cdylib` artifacts, generates a public C header, and documents direct C/C++ use, so lockstep Swift packaging does not make this ABI change safe. The v4.1.0 JNI export at `packages/rs-unified-sdk-jni/src/funding.rs:98-104` likewise retains its short JNI symbol while inserting `manager_handle`, allowing a mismatched Kotlin wrapper and native library to resolve the same symbol with different descriptors. Preserve the released entry points and add manager-aware symbols under new names; updated Swift and Kotlin wrappers can use the new symbols while the legacy estimator retains its previous versionless behavior.
…ol-version ratchet The SDK learns the network's protocol version on a background refresh after the send screens can already appear, so fee previews resolved before the ratchet completed were computed at the seed version and cached. Swift re-runs resolveShieldedFees() (guard dropped — the recompute is a pure handle lookup) when AppState publishes platformProtocolVersion; the Kotlin screens key their fee producers on the same published version.

Preliminary review — Codex only
The manager-backed estimator and protocol-boundary tests correctly select fees from the manager SDK's active version, and the prior asynchronous startup-cache issue is fixed. The PR still changes released C and JNI symbols in place, creating an unsafe ABI mismatch, and the example applications do not refresh cached estimates after later metadata-driven version ratchets.

- [SUGGESTION] packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Core/Views/SendTransactionView.swift:358-364: Refresh estimates after metadata-driven protocol ratchets
This observer reruns fee estimation only when `AppState.platformProtocolVersion` changes, but that property is written solely by the one startup/network-switch refresh.

The Kotlin screens have the same gap because their `protocolVersion` key comes from the equivalent one-shot `AppState` flow.

(existing thread: https://github.com/dashpay/platform/pull/4470#discussion_r3845329252)
The v4.0.0 and v4.1.1 releases export `platform_wallet_shielded_estimate_fee(kind, num_actions, out_fee)`, while this PR changes that same unmangled symbol to `(handle, kind, num_actions, out_fee)`. The crate ships `staticlib` and `cdylib` artifacts, generates a C header, and explicitly documents direct C/C++ integration, so independently compiled callers can resolve this symbol while using the old calling convention. For example, a new caller loading the old library makes the old implementation interpret `num_actions` as `out_fee`, potentially writing through a small integer address; the inverse mismatch also invokes Rust with shifted or missing arguments. The released short JNI symbol at `packages/rs-unified-sdk-jni/src/funding.rs:98-104` is changed similarly by inserting `manager_handle`, and JNI short-name lookup does not encode the descriptor. Preserve the released C and JNI entry points with their original signatures, add separately named manager-aware exports, and route the current Swift and Kotlin wrappers through those new symbols. The legacy estimator can retain its previous versionless behavior for binary compatibility and be deprecated.

Fixed in 6e95fe7 — no new FFI export; the estimator already resolves the live version on every call.
platform_wallet_shielded_estimate_fee reads manager.sdk().version() per invocation with no round-trip and no caching (rs-platform-wallet-ffi/src/shielded_send.rs), so the apps do not need an observable for the SDK version — they only need to re-read at the points where the value is consumed. AppState.platformProtocolVersion stays as the cheap early trigger; it is no longer the only one.
Swift (SendTransactionView.swift): resolveShieldedFees() now also runs in the Send action, synchronously before the Task that calls executeSend. That read is the one taken closest to submission, so a preview built at the seed version cannot survive into a send whose builders carve at a ratcheted sdk.version(). Covers both paths you flagged: the swallowed proven-fetch failure that republishes the unchanged seed, and an activation landing while the sheet stays open.
Kotlin (SendTransactionScreen.kt, ShieldedFundScreen.kt): the fee is display-only on these screens (canSend never reads it), so a submit-time re-read would only refresh a value the user is navigating away from. Instead both fee producers gained a resume epoch key — LifecycleResumeEffect bumps it, so the estimate is re-read on navigation to the screen and on app foreground, which is where a stale number is actually visible. LifecycleResumeEffect comes from lifecycle-runtime-compose, the same artifact already supplying collectAsStateWithLifecycle.
Verification: Kotlin and Swift were both verified by reading rather than compiling. The Swift build needs DashSDKFFI.xcframework, which is not present in this worktree (a 10-20 min rebuild); the Gradle compile needs an Android SDK location that is not configured here. I did confirm the two new API usages against the actual cached artifacts rather than from memory — LifecycleResumeEffect(key1, …) with the onPauseOrDispose scope exists in lifecycle-runtime-compose-android 2.9.0, and produceState's vararg-keys overload exists in compose-runtime 1.8.1, which is what the four-key call now resolves to.
🤖 Addressed by Claude Code
…e version The published AppState.platformProtocolVersion is not a complete signal for "the estimator's version changed": refresh_protocol_version() swallows a failed proven fetch and returns the unchanged seed, and the SDK ratchets its shared AtomicU32 from any proof-verified query's response metadata without publishing at all. Keying estimation solely on that value let a preview keep a seed-version fee while the submission builders read the newer sdk.version(). The estimator FFI already resolves manager.sdk().version() on every call with no round-trip, so no new export is needed - the apps just have to re-read at the points where the value matters. Swift re-resolves in the Send action, so the fee the coverage math and the summary use is the one taken closest to submission; the Kotlin screens re-key their fee producers on a resume epoch, covering both a transient startup failure and an activation that lands while the screen stays open.

Brings the branch up to date with upstream after #4457, #4465, #4399, #4467, #4257, #4382, #4423, #4463, #4377, #4440, #4472, #4477, #4470, and #4469 landed on v4.2-dev (base tip 1e26927). One conflict, in packages/kotlin-sdk/.../dashsdk/wallet/ManagedCoreWallet.kt: upstream #4377 inserts a new setGapLimit() immediately above broadcastTransaction(), while this branch rewrites that same broadcastTransaction() — expanding its KDoc to document the age-guard refusal and wrapping the body in mapNativeErrors { } so the native stale-broadcast error (code 34) surfaces typed. The two edits are additive and independent, so resolved as the union: setGapLimit() kept verbatim from upstream, broadcastTransaction() kept verbatim from this branch. Three more files overlapped but auto-merged, and were verified rather than assumed: - changeset/core_bridge.rs: this branch factors the input walk into spent_outpoint()/spent_outpoints() so the in-broadcast fence and the persister's spent-set cannot disagree about which inputs count; upstream #4257 replaces the synthetic ScriptBuf::default() with the input's real locking script. Orthogonal — #4257 changes the Utxo payload, the fence's filter predicate is unchanged. Both sides' tests pass, including #4257's two new script-reconstruction tests running through this branch's refactored walk. - manager/mod.rs: upstream adds the tracked_masternodes field and its initializer; this branch's SpendObservationHandler registration and its cfg(any(test, feature = "shielded")) widening are untouched. - rs-platform-wallet-ffi/src/error.rs: upstream adds ErrorMasternodeListUnavailable = 46; this branch maps PlatformWalletError::StaleReservation onto the existing shared code 34. No discriminant or name collides. Upstream's three new PlatformWalletPersistence methods all carry default bodies, so this branch's NoopTestPersister needs no change. Verified: the merged tree is identical to origin/v4.2-dev except in exactly the 18 files this branch owns, and this branch's net delta against the new base is unchanged at +3457/-103. cargo test -p platform-wallet --lib: 784 passed, 0 failed. cargo test -p platform-wallet-ffi --lib: 278 passed, 0 failed. cargo fmt --check and cargo clippy --all-targets -D warnings: clean on both crates.

Post-merge note: this PR's active-protocol-version fee change breaks a test fixture on v4.2-dev when the shielded suite runs — |
Brings the shielded-invite branch up to date with upstream v4.2-dev (#4470 active-protocol-version shielded fees, #4472 shield credits to an external Orchard recipient, #4477, #4469 swift async shutdown). One conflict, in rs-platform-wallet/src/wallet/shielded/operations.rs: both sides appended a #[cfg(test)] module at the same insertion point — this branch's foreign_claim_guard_tests (single-flight claim lifecycle guard, #4313 review finding 979bbc2fcb3c) and upstream #4472's shield_recipient_tests (resolve_shield_recipient classification). Resolved by keeping BOTH modules in full, this branch's first, each under its own #[cfg(test)]. No code from either side dropped or altered. The FFI error-code seam needed no hand-merge: upstream #4469's ErrorMasternodeListUnavailable = 46 was allocated explicitly around this branch's 43/44/45 shielded-invite trio. Verified: cargo check -p platform-wallet --features shielded and platform-wallet-ffi --all-features clean; cargo test platform-wallet --features shielded --lib = 984 passed / 1 failed — shield_input_selection_tests::regression_reports_max_from_usable_suffix _not_total_account_balance, proven PRE-EXISTING on unmerged origin/v4.2-dev (1e26927): upstream's versioned-fee change dropped shield_fee_reserve_credits(LATEST) below the test's seeded 297_264_780 leading balance; the unmerged PR head passes it. platform-wallet-ffi = 330 passed / 0 failed; rs-unified-sdk-jni = 37 passed / 0 failed; kotlin-sdk :sdk:test = 353 tests x debug+release, 0 failures.

…4470 active-version fees + #4472 shield-to-recipient) Reconciles the branch with the active-protocol-version fee estimation (#4470), the shield-to-external-Orchard-recipient operation (#4472), the block-time truncation fix (#4477) and the async wallet-manager shutdown (#4469). One textual conflict, packages/rs-platform-wallet-ffi/src/shielded_send.rs, plus one silent auto-merge hazard in the same file: - Duplicate guard helpers (auto-merged, NOT flagged by git). #4472 adopted this branch's panic-guard split verbatim, so the merge kept BOTH copies of panic_payload_message / catch_panic_to_code / SPEND_PANIC_GUIDANCE / catch_spend_panic. The bodies are byte identical; this branch's copy is a strict superset (it also carries IDENTITY_CREATE_PANIC_GUIDANCE, ASSET_LOCK_FUNDING_PANIC_GUIDANCE and SEED_POOL_PANIC_GUIDANCE for its non-spend guard call sites). Kept this branch's block, deleted upstream's duplicate, and widened the SPEND_PANIC_GUIDANCE doc to name shield-to-recipient among the operations it covers. - The shared guard tests. Upstream re-labelled the operation string in catch_spend_panic_maps_a_panic_to_the_unconfirmed_contract from "shielded multi-output transfer" to "shielded shield to recipient" and dropped the #4312 review-finding citation. Kept this branch's labels and citation (one test name, one definition); the guard the new export uses is exercised either way, and this branch's catch_panic_to_code_carries_the_per_operation_contract and max_recipients_matches_the_effective_action_ceiling tests survive. Everything else interleaved cleanly and was verified rather than assumed: this branch's four catch_pre_broadcast_panic sites (unshield / transfer / transfer_multi / withdraw) and catch_pre_broadcast_panic_async sit outside shield(), which is the only function #4472 rewrote in operations.rs (into shield + shield_to + resolve_shield_recipient), so both survive whole. No FFI export and no test was lost from either side: the merged shielded_send.rs gains exactly platform_wallet_manager_shielded_shield_to_recipient, and the only retired test is upstream's own rename of estimate_fee_matches_observed_onchain_values_for_2_actions into its protocol-13 / protocol-14 / manager-handle triple. No fee numbers needed recalibrating, and the output-aware predictor needed no change to adopt #4470's active-version sourcing: it is already version-parameterized end to end and every production call site feeds it sdk.version() -- the same network-tracked accessor #4470 switched the FFI estimator to. ShieldedFeeKind::compute takes &PlatformVersion (note_selection.rs:56); select_notes_with_fee and select_notes_for_denomination thread it through (:197-207, :288-311); reserve_unspent_notes and its denomination sibling pass sdk.version() (operations.rs:2329, :2362), as do shield's fee carve (:593) and every builder call (:647, :887, :1081, :1285, :1495, :1708, :1907). PlatformVersion::latest() survives only in #[cfg(test)] fixtures and in MAX_SHIELDED_TRANSFER_RECIPIENTS's ceiling assertion -- a structural action bound, not a fee, and version-invariant in any case (max_shielded_transition_actions = 16 and max_state_transition_size = 20480 in every system_limits version, so protocol 13 and 14 yield the same ceiling of 6). The shield_input_selection fixture survives because it derives: reserve() calls shield_fee_reserve_credits(LATEST_PLATFORM_VERSION) (platform_wallet.rs:2203) rather than pinning a literal, so it tracks any fee-constant movement automatically. #4470 did not touch reserves at all. Verified: cargo fmt --check and cargo clippy clean on platform-wallet, platform-wallet-ffi, dpp and rs-unified-sdk-jni. Tests: 942 passed platform-wallet (--features shielded --lib), including all four *_prover_panic_releases_the_note_reservation tests, all twelve shield_input_selection_tests and #4472's four shield_recipient_tests; 294 passed platform-wallet-ffi (--features shielded --lib), including #4470's estimate_fee protocol-13 / protocol-14 / manager-handle / unknown-handle tests; 241 passed dpp shielded (--all-features --lib shielded), including all three wire_cost_measured_tests. 0 failures.

platform_wallet_shielded_estimate_feepinnedPlatformVersion::latest()and took no manager handle, so once a client ships the protocol-14 fee rebalance (#4467) its fee preview under-quotes any network still running protocol 13: 114,140,000 vs the 162,851,200 credits the consensus gate actually validates for a 2-action transfer. The shielded builders don't have this problem — they carve fees at the manager's network-trackedsdk.version(). Raised by review on #4467 (resolved there as a follow-up).What was done?
platform_wallet_shielded_estimate_feenow takes the managerHandleand resolves the fee formula's version through the manager's SDK (sdk().version()), exactly like the builders. An unknown handle is a hardErrorInvalidHandle— a versionless fallback would silently mis-quote. The kind → formula mapping is factored into a version-explicit selector so the boundary is unit-testable.estimateShieldedFeebecomes an instance method onPlatformWalletManager(it needs the handle). SwiftExampleApp'sSendViewModelreads view-pushed estimates (same pattern asplatformMinOutputAmount— the view model holds no wallet handle).ShieldedProverontoPlatformWalletManager, matching the other manager-handle entry points. Both example-app screens now estimate through the active manager.How Has This Been Tested?
cargo test -p platform-wallet-ffi --all-features shielded_send— 14 pass, including both protocol-boundary pins.cargo clippy -p platform-wallet-ffi -p rs-unified-sdk-jni --all-features --all-targets— clean.:sdk:compileDebugKotlinand:app:compileDebugKotlin— clean.SwiftDashSDKbuilds for the iOS simulator against the regeneratedplatform-wallet-ffiheader; SwiftExampleApp sources compile (final link needs the rebuilt xcframework, as usual for FFI signature changes).Breaking Changes
None on-chain. Host-facing FFI/SDK signature change:
platform_wallet_shielded_estimate_feegains a leading manager-handle parameter; the Swift method is now an instance method and the Kotlin wrapper moved toPlatformWalletManager.Checklist:
