The Core→Platform transfer (Route 5, AssetLockAddressTopUp) locked exactly the typed amount, and the funding state transition's metered fee was carved out of the lock by the remainder recipient — so the Platform balance received less than the user typed (~15k duffs short on testnet). Mirror the Core→Shielded fee-on-top model: a new CoreToPlatformAmountPolicy inflates the lock by a 50k-duff headroom (the Rust-side required processing balance for address funding), so the Platform balance receives at least the typed amount and the unspent headroom lands back on it. The coordinator gains a zero-amount/overflow fail-closed guard (previously a topup below 50k duffs could build a lock unable to cover its own processing cost); canContinue, the insufficient-balance message, Max, and the confirm sheet's Network fee/Total rows all price the headroom on top. Verified on a testnet simulator smoke: typed 0.05 DASH → lock 5_050_000 duffs, credited 5_035_297_840 credits (= 0.05035 DASH), L1 miner fee still on top.

📝 WalkthroughWalkthroughCore-to-Platform transfers now use a deterministic funding reserve based on the Platform admission floor. Validation, Max handling, funding, confirmation totals, fee display, overflow handling, regression tests, and localized guidance use the reserve-based flow. ChangesCore-to-Platform funding reserve
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: ⚪ Minimal · up to The change ensures Core-to-Platform top-ups reserve the network fee so recipients receive at least the entered amount, with boundary and smoke verification described in the PR. Remaining issues are limited to localized wording consistency and a trivial lint cleanup; no actionable merge-blocking risk remains. Sequence Diagram(s)sequenceDiagram

The confirm sheet computed the network-fee and total rows inside the View struct — fee math the guardrails ban there. Move the resolution into InternalTransferViewModel (confirmNetworkFeeCredits / confirmTotalDuffs) and freeze the resolved values into the InternalTransferConfirmation submission, following the existing withdrawalFeeCredits precedent; the sheet now only formats.

…eadroom Platform validates the lock against calculate_min_required_fee = the 50k-duff processing base PLUS address_funds_transfer_output_cost (6M credits) per output — 56k duffs for our one-output funding. The 50k headroom let 1–5,999-duff topups pass canContinue, broadcast a 50,001–55,999-duff lock, and get rejected by Platform after the L1 broadcast, stranding the outpoint (a resume reuses the same too-small lock). Raise the headroom to the full minimum lock cost (56k duffs), so every lock clears the Platform-side minimum by construction — no route minimum needed. Also spell out in the confirm sheet's tip that the network fee is a reserve whose unused part is credited back to the Platform balance. Boundary test added: a 1-duff topup locks 56,001 duffs, strictly above the minimum. Verified on a testnet simulator smoke at the previously-broken boundary: typed 0.00005 DASH (5,000 duffs) → lock 61,000 duffs, funding ST accepted (lock consumed), credited 46,055,420 credits.

…adroom Consume the new SDK expected-fee estimator (estimateAddressFundingFee, pinned by the platform-side calibration tests) on the Core→Platform route: - The lock headroom is now the expected fee (~17.5k duffs) instead of the full 56k-duff minimum-lock reserve — the recipient lands within a couple thousand duffs of the typed amount instead of ~41k over. The protocol's minimum-lock floor still raises the lock to 56,001 duffs, but only for micro amounts where it actually binds; with no estimate the policy falls back to the full 56k headroom. - The confirm sheet's Network fee row shows the estimate, so Amount + Network fee = Total again for normal amounts. The Fee reserve row now appears only for micro topups (surfacing the floor-forced extra, which returns to the Platform balance). - canContinue, the insufficient-balance message, Max, Total, and the executed lock all derive from the same CoreToPlatformAmountPolicy.headroomDuffs(forAmountDuffs:expectedFeeDuffs:). Policy tests updated: normal-amount headroom equals the fee, micro amounts raise the lock to the floor (with the exact kick-in boundary), missing-estimate fallback, and overflow fail-closed. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…e, not the fee estimate The SDK's expected-fee estimate is display-only with no formal upper-bound guarantee: the charged fee is metered on live state, the stuck-ST retry loop bumps user_fee_increase up to +14%, and drive-abci's validate_fees_of_event gate additionally requires the lock to cover an average-case estimate. Sizing the lock as amount + estimate could silently shrink the amount the Platform balance receives below what the user confirmed (ReduceOutput on the single remainder). Lock sizing is now amount + a 56k-duff wallet funding reserve (equal to the admission floor) - deterministic, no FFI, one policy function shared by validation, Max, the confirm sheet and the executed lock, so the confirmed Total and the executed lock cannot diverge. The estimate is demoted to an informational "Estimated Platform fee" row (fetched once per view model); the sheet shows the full "Fee reserve" separately, with Amount + Fee reserve = Total, and the tip explains the fee comes out of the reserve with the unused part credited to the Platform balance. Reserve adequacy (actual fee, max-retry fee increase, minimal-lock admission through both gates, cross-version estimate stability) is pinned by the drive-abci expected_fee_calibration tests on the platform side. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…localizations Follow-up to the deterministic funding-reserve change, three fixes: - Honest contract: the 56k reserve is documented as a TEMPORARY wallet-chosen policy - the Platform balance receives lock - actual fee, and the drive-abci calibration tests are regression samples for specific versions/scenarios, not a proof of an upper bound on arbitrary live GroveDB state. All comments implying a formal guarantee are reworded. - Max notice: the Core->Platform held-back line is now derived from the executed lock (balance - (amount + reserve)), so the funding reserve - which leaves Core inside the asset lock - is no longer reported as held back, and the notice is skipped when nothing actually stays in Core. New policy helper maxHeldBackDuffs with tests. - Localizations: "Estimated Platform fee", "Fee reserve" and the new Core->Platform privacy tip added to all 43 Localizable.strings catalogs with real translations reusing each locale's existing terminology (the tip's first sentence reuses the locale's existing translation of the previous tip).

Keep the Albanian wording formal and explicit.
Line 3957 changes from formal juaj to informal tënd. It also does not explicitly state that the unused part of the fee reserve is credited back. Use consistent formal wording and name the unused reserve directly.

Use the existing Serbian term for Platform balance.
Line 3957 uses Platform saldu, while this catalog already translates Platform balance as Platform stanje at Lines 2799 and 4977. Use the existing term for consistent UI wording.

…quote Replace the static 56k-duff funding reserve with the new server-side getAddressFundingFeeQuote API (SwiftDashSDK ManagedPlatformAddressWallet.quoteFundingFee): - InternalTransferViewModel runs an async quote preflight on route entry (generation-tokened, cancel-safe). Quotes are requested with userFeeIncrease=14 - the SDK retry loop's ceiling - so the estimate already carries the retry margin and no extra app margin is applied. - CoreToPlatformAmountPolicy is now pure quote math: reserve = max(estimatedFee, minimumRequiredLock - amount*1000) rounded up to whole duffs, lock = amount + reserve, overflow -> nil. The lock always clears the admission floor and the reserve always covers the quoted fee; the user-entered amount is never undercredited. - Fail closed everywhere: while the quote is loading/unavailable, Continue is disabled, Max fills 0, and the inline message says the fee quote is unavailable. There is NO production fallback to the old reserve; a dev-only, default-off useDevFallbackQuote flag (#if DEBUG || DASH_TESTNET) reproduces the old 56k policy for networks whose DAPI does not serve the endpoint yet. - The lock value is FROZEN into the confirmed submission: performFundPlatform(recipientAmountDuffs:lockValueDuffs:) executes the ViewModel-resolved value verbatim (and logs both) instead of recomputing the reserve; the confirmed Total is exactly the executed lock. Resume/Try again with a committed lock still reuses the same outpoint and never re-quotes. - Confirm sheet simplified: the separate "Fee reserve" row is removed; "Estimated Platform fee" (advisory, "~"-prefixed) and "Total" remain. - Localizations: obsolete "Fee reserve" and credited-back tip removed from all 43 catalogs; new quote loading/unavailable strings added with translations; the topup tip reuses the existing short translated key. - Tests: 56k policy tests replaced with mock-quote tests (floor-topping tiny amounts, ceil rounding, Max == spendable lock, held-back, and overflow fail-closed). Test target remains broken pre-existing; tests are compile-ready. Requires a platform checkout with the address-funding-fee-quote stack (rs-drive engine, DAPI endpoint, client plumbing, FFI + Swift wrapper). End-to-end against public DAPI stays blocked until the endpoint is deployed; verified via dashpay build + policy unit tests. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

The Core→Platform transfer (Route 5,
AssetLockAddressTopUp) locked exactly the typed amount. The funding state transition's metered fee (~15k duffs on testnet) is deducted from the locked value by the mandatory remainder recipient, so the Platform balance received less than the user typed — e.g. a 1 DASH transfer credited 0.99985 DASH.Fix
Mirror the Core→Shielded fee-on-top model — the sender covers the fee, the recipient balance never receives less than the typed amount. The reserve on top of the amount is sized from the live server-side fee quote (
getAddressFundingFeeQuote, via SwiftDashSDKManagedPlatformAddressWallet.quoteFundingFee), replacing the interim static 56k-duff policy this PR originally shipped:InternalTransferViewModel: entering the Core→Platform route fetches a quote for the wallet's own next Platform receive address (the same recipientfundFromCoreresolves). Quotes are requested withuserFeeIncrease = 14— the SDK retry loop's ceiling — so the estimate already includes the retry margin; no extra app-side margin is stacked on top.CoreToPlatformAmountPolicy, pure + unit-tested):reserveCredits = max(estimatedFeeCredits, minimumRequiredLockCredits − amount×1000), rounded up to whole duffs;lock = amount + reserve. The lock always clears the consensus admission floor (a tiny topup is topped up to it — the surplus is credited to the Platform balance, in the user's favor) and the reserve always covers the quoted fee. Overflow →nil→ fail closed.useDevFallbackQuoteflag (#if DEBUG || DASH_TESTNET,TODO(quote-dapi)) reproduces the old 56k policy for networks whose DAPI doesn't serve the endpoint yet.lockValueDuffsfrom the quote at Continue and freezes it into the confirmation;performFundPlatform(recipientAmountDuffs:lockValueDuffs:)executes that value verbatim (logging both) and never recomputes the reserve — the Total the user confirms is exactly the lock executed. Resume/"Try again" with a committed lock reuses the same outpoint and never re-quotes.~-prefixed — the quote is planning data from a single node, not a guaranteed bound) and "Total" (the exact executed lock). Obsolete "unused reserve is credited back" copy removed from all 43 localization catalogs; new quote loading/unavailable strings added with translations.A two-recipient "exact credit + change address" split was considered and rejected: the protocol requires exactly one remainder recipient and rejects duplicate addresses, and the SDK has a latent
remainderIndexordering bug with >1 recipient — tracked separately for an upstream fix.Verification
dashpayarm64 simulator build with the quote-capable platform checkout (see below).CoreToPlatformAmountPolicy: reserve = rounded-up quoted fee, tiny-amount floor topping, Max amount locks exactly the spendable balance (confirmed Total ≡ executed lock), held-back excludes the reserve, overflow fail-closed.

Until the platform-side stack (rs-drive quote engine → DAPI endpoint → rs-dapi-client/rs-sdk/rs-platform-wallet → platform-wallet-ffi + Swift wrapper) is deployed on the target network, the Core→Platform route fails closed in this build: Continue stays disabled with "The network fee quote is unavailable…".
