feat(platform-wallet): locate and track masternodes independently of any wallet - #4465
Merged
Conversation
…library crate The masternode aggregation (`MasternodeAggregate`, `aggregate_masternodes`, `MasternodeStatus`, `ListMembership`, the DIP-3 payload decode) lived in `rs-platform-wallet-ffi`, so the only way to get a wallet's masternodes was through the C ABI — Android's JNI shim and any other host would have had to re-implement it. It now lives in `platform_wallet::masternode` as `MasternodeRecord`, with one library entry point, `PlatformWalletManager::wallet_masternodes_blocking`, that does what the FFI list function and the withdrawal path each did on their own: aggregate the wallet's provider transactions, resolve status against the DML snapshot, and resolve operator / platform-node key ownership by derive-and-compare. `MasternodeEntryFFI` is unchanged on the wire; `masternode_entry_ffi` is now pure marshalling from the record (`order_index`, `operator_key_index`, `platform_key_index`, `platform_ownership_checked` ride on the record instead of being computed at the FFI boundary). `MasternodeRecord` carries a `source: MasternodeSource` (only `Wallet` today) so records from other provenances can share the same shape. The aggregation tests move with the code; the FFI keeps a gating test for the entry marshalling.
… its private keys A host pastes one string and gets back the masternode(s) it names, plus — for a private key — the role that key fills on each, so the key can be dropped into the right field without re-entering it. `platform_wallet::masternode::locator`: * `parse_locator_input` reads IPs (bare, `ip:port`, a DAPI URL, IPv6), display-order proTxHashes, owner/voting/payout keys as WIF (network- checked) or hex, operator BLS hex, and Tenderdash node keys in dashmate's base64 or hex (`seed ‖ pub`, public half cross-checked). A 64-hex string is ambiguous — proTxHash, secp256k1, BLS or ed25519 — so every reading is a candidate and the list decides. * `locate_in_summaries` resolves candidates against a typed snapshot of the deterministic masternode list (`masternode::list`: proTxHash, service address as `SocketAddr`, operator key, voting key id, platform node id, validity). Secrets match by deriving the public side: voting key id, operator key in BOTH basic and legacy serialization, node id = `SHA256(pk)[..20]`. * `MasternodeLocator::locate` adds an opt-in Platform step for secp256k1 keys: owner and payout keys are not on the list, but the masternode identities hold them non-unique-indexed (owner identity = proTxHash: key 0 payout TRANSFER, key 1 owner OWNER; operator identity: operator payout TRANSFER), so `getIdentityByNonUniquePublicKeyHash` finds them. * `verify_masternode_key` is the same derive-and-compare for attaching a key to a role; `Unverifiable` when the reference isn't known — never a pass. FFI: `platform_wallet_manager_locate_masternode` (+ free) and `platform_wallet_manager_masternode_verify_key`, new result code `ErrorMasternodeListUnavailable` (43). The locate snapshots SPV/SDK handles and the wallets' own masternodes under the handle guard, then runs on a worker so a Platform round-trip never holds it. Swift: `PlatformWalletManager.locateMasternode(_:searchPlatform:)`, `verifyMasternodeKey(proTxHash:role:key:)`, `MasternodeKeyRole` (raw values line up with Android's `MasternodeKeyType`). Tests cover every input form, wrong-network WIF, corrupt node keys, out-of-range scalars, all five list lookups on synthetic lists, legacy vs basic BLS, role detection from owner/operator identities, and verification per role.
A user can now follow any masternode / evonode — located via the new
locator — without it belonging to a wallet: track it (with an optional
label), enrich it, and act on it with host-supplied keys. Nothing here
touches the wallet-derived masternode feature; tracked records ride the
same `MasternodeRecord` / `MasternodeEntryFFI` shape with
`source == Tracked` (+ `label`), so hosts render both with one code path.
`masternode::tracked`:
* `TrackedMasternode` — proTxHash, label, added_at, and a versioned
snapshot of everything learned so far: the DML entry, the Platform
identity key hashes (owner identity key 0 = payout TRANSFER, key 1 =
owner OWNER; operator identity payout), and the ProRegTx details
(height, collateral, original keys) via DAPI Core `getTransaction`.
Unknown stays unknown — status is Active / Inactive / Retired only
against a live list, `Unknown` while masternode sync is behind.
* `TrackedMasternodes` — a cloneable service handle (registry + SPV +
SDK + persister Arcs) so refresh / withdraw run on workers without
holding the manager. Track seeds from the current list (local);
`refresh` does the network enrichment, keeping and persisting partial
results before surfacing an error.
* `withdraw` signs an owner-identity credit withdrawal with a
host-supplied owner or payout-address key (`RawSecretCoreSigner`), the
same execution path as the wallet-scoped withdraw — extracted as
`execute_masternode_withdrawal`, error contract unchanged. The key is
checked against the snapshot hash before any network work and used per
call only: Rust never stores a tracked secret (host Keychain /
Keystore own them), mirroring `cast_vote`.
* `capabilities_for_roles` — the shared gating policy (owner OR payout
key ⇒ withdraw, voting ⇒ vote, operator ⇒ update service).
Persistence is a whole-set replace per network with an honest default:
new `PlatformWalletPersistence::{persist,load}_tracked_masternodes`
(default no-op ⇒ session-scoped) + capability bit
`TRACKED_MASTERNODES` (1 << 10). SQLite gets migration V006 +
`schema::tracked_masternodes` (snapshot as an opaque PUBLIC-material
JSON document; secrets_scan stays green). The FFI persister negotiates a
persist/load/free trio through the additive size-gated
`PersistenceCallbacksExtension` (version stays 1; older hosts' smaller
struct_size reads as None; the JNI builds the extension via
`..Default::default()` and is unaffected). Swift implements the trio
over a new `PersistentTrackedMasternode` SwiftData row keyed by
(networkRaw, proTxHash) — deliberately NOT `PersistentMasternode`, whose
non-optional walletId is its uniqueness key and network pivot.
FFI: track / untrack / set-label / list / refresh / withdraw +
`platform_wallet_masternode_capabilities`; locate matches now carry
`already_tracked`. Swift wrappers on `PlatformWalletManager`
(`trackMasternode`, `trackedMasternodes()`, `refreshTrackedMasternode`,
`trackedMasternodeWithdraw`, `MasternodeCapabilities(holding:)`),
`PlatformMasternode.source/.label`.
Tests: snapshot JSON round-trip and degradation, record building per
list state (live / cached / retired / unavailable), key-reference
precedence, capabilities, per-type numbering, ProRegTx lifting, SQLite
replace/scoping/restart round-trip, FFI host-callback round-trip with
loan/free accounting, extension size-gating (dpns-only-sized hosts),
and Swift capability + SwiftData uniqueness tests. The example app
builds warnings-as-errors against the new API.

@bfoss765 Confirmed against #4313's head — it does claim 43/44/45 across all three layers, so Also fixed in the same push: the 🤖 Addressed by Claude Code |
…loader hygiene CodeRabbit round on #4465 — all seven confirmed against the code: * `persistence_extension_callbacks` computes each field's size from its TYPE (`size_of::<Option<Fn>>()`); `size_of_val(&(*ext).field)` formed a reference to a place that can lie outside a shorter caller's allocation — the exact case the gate exists for. * `FFIPersister::load_tracked_masternodes` fails closed when the load callback arrives without its free callback (every load would leak the host allocation), matching the shielded load/free pairing rule. * `PersistenceCapabilities::names()` registers `tracked_masternodes`, and the v1 bit-stability test pins 0x400. * `untrack_blocking` persists unconditionally: a failed write after the in-memory removal used to strand the row on disk, and the retry's `removed == false` path skipped the persist — resurrecting the node on the next start. * `refresh` writes its snapshot back only while the node is STILL tracked (an untrack that raced the network calls wins) and re-reads the live label so a concurrent rename isn't overwritten. * Locator matches bracket a bare IPv6 literal in `platformDAPIAddress`, mirroring `PlatformMasternode` (defense in depth — locator hosts come from Rust `SocketAddr` strings, which are already bracketed). * The Swift tracked-masternode loader SKIPS a row whose stored proTxHash isn't 32 bytes (shielded-loader convention) instead of keying a phantom masternode on zeros that a later whole-set persist would make real.

…ashcore-dev-961 Brings in five commits; #4465 (wallet-independent tracked masternodes) collides with this branch's persistence-capability and persistence- extension surfaces. Seven files conflicted, and two more collisions arrived textually clean and had to be resolved by hand. Capability-bit collision: v4.2-dev's TRACKED_MASTERNODES and this branch's CORE_SWEEP_REMOVAL both claimed bit 10 (0x400) — the auto-merge even left both `1 << 10` constants in the file without a conflict marker. The file's contract makes v1 bit meanings append-only (existing values are never renumbered or reused), and TRACKED_MASTERNODES is already merged on the mainline, so its assignment is the published one; this branch's unmerged bits are the ones that move: CORE_SWEEP_REMOVAL 1<<10 → 1<<11 (0x800), DASHPAY_PAYMENTS 1<<11 → 1<<12 (0x1000). Mirrored across the FFI C constants, the Swift and Kotlin declarations (Kotlin also gains a TRACKED_MASTERNODES mirror constant, unattested on Android), the v1 stability pins (Kotlin handler pin 0x7bf → 0xbbf), the KNOWN names table (now naming all three bits), and the name-coverage loop bound (0..13). Renumbering is safe because the bits are negotiated at runtime between Rust and the host inside one app binary and are never persisted: no schema column, no serialized model, no defaults store records them anywhere. Persistence-extension slot ordering: both sides appended to the size-negotiated PersistenceCallbacksExtension after the DPNS slot — mainline the tracked-masternode trio, this branch the sweeps and chainlock-height slots. Slot order is the ABI under version 1 and mainline's trio is the published layout, so the merged order is dpns → persist/load/free tracked masternodes → sweeps → chainlock height. The layout test now pins the full offset-adjacency chain, and the negotiation test walks every historical struct_size boundary (DPNS-era, masternode-era, sweeps-era, current). The per-slot reader fns were merged into mainline's single persistence_extension_callbacks() shape, implemented on this branch's negotiated_extension_slot! gate, and FFIPersister keeps both constructor families with new_with_persistence_capabilities_and_extensions as the base. Migration collision (textually clean, semantically fatal): both sides added a V006 refinery migration. Mainline's V006__tracked_masternodes is merged and keeps the number; this branch's V006__utxo_sweep_winner_height is renumbered to V007. Pre-release dev databases that applied the old V006 hit refinery's divergence check and must be recreated (the same policy V001's test documents). sqlite/persister.rs, PlatformWalletPersistenceHandler.swift and InvitationPersistenceTests.swift resolve as unions: both stores genuinely implement both features, so they attest all three bits and wire all six extension slots. Not lost, relocated: #4465 moved ten provider-tx aggregation tests from ffi/core_wallet_types.rs into platform-wallet/src/masternode/record.rs; the merge follows the move. One textually-clean semantic break fixed in PlatformWalletPersistenceHandler.swift: mainline's persistTrackedMasternodes staged rows on the shared round context and, with a changeset round open, returned success while deferring the save to endChangeset. That was benign on mainline, but this branch gave endChangeset a new rollback trigger (an unresolvable DashPay deferred-payment owner calls rollback()) and widened the round window across the sweeps extension callback — so an unrelated round failure could silently revert a registry write Rust was already told succeeded, resurrecting an untracked masternode with nothing to re-issue the removal. The persist now runs on its own dedicated ModelContext and saves before returning, honouring the Rust contract that registry writes are not round-scoped. The sweep-tombstone GC logic is untouched.

refactor(platform-wallet)— move the masternode model into the library crateMasternodeAggregate+ the DIP-3 aggregation lived inrs-platform-wallet-ffi, so the only way to get a wallet's masternodes was the C ABI. It is nowplatform_wallet::masternode::MasternodeRecordwith one entry point,wallet_masternodes_blocking(aggregation + DML status + operator/platform ownership), that the FFI list function and the withdrawal path both share.MasternodeEntryFFIunchanged on the wire;masternode_entry_ffiis pure marshalling now.2.
feat(platform-wallet)— the locatorparse_locator_input: IPs (bare /ip:port/ DAPI URL / IPv6), display-order proTxHashes, owner/voting/payout WIF (network-checked) or hex, operator BLS hex, Tenderdash node keys (dashmate base64 / hex, public half cross-checked). 64 hex chars is ambiguous — every reading becomes a candidate and the list decides.locate_in_summaries: pure resolution against a typed DML snapshot (MasternodeListSummary); secrets match by derived voting key id, operator key in both basic and legacy serialization, node id =SHA256(pk)[..20].MasternodeLocator::locate: opt-in Platform step for secp256k1 keys — owner/payout keys aren't on the list, but the masternode identities hold them non-unique-indexed (owner identity = proTxHash: key 0 payout TRANSFER, key 1 owner OWNER; operator identity: operator payout TRANSFER), sogetIdentityByNonUniquePublicKeyHashfinds them. Opt-in because it reveals the key's public hash to a DAPI node.verify_masternode_key: the attach-time derive-and-compare;Unverifiablewhen the reference isn't known — never a pass.3.
feat(platform-wallet)— the tracked registryTrackedMasternoderows (proTxHash, label, added_at, snapshot) with enrichment from the DML, the node's Platform owner + operator identities, and its ProRegTx via DAPI CoregetTransaction(registration height, collateral, original keys). Status is honest: Active/Inactive/Retired only against a live list, Unknown while masternode sync is behind.TrackedMasternodesservice handle (Arcs over registry/SPV/SDK/persister) so refresh/withdraw run on workers without holding the manager.RawSecretCoreSigner) over the sameexecute_masternode_withdrawalpath as feat(platform-wallet): claim masternode credits with the owner or payout key #4451 — error contract unchanged, key checked against the snapshot before any network work, used per call and never retained (mirrorscast_vote). Rust never stores a tracked secret; hosts keep them in Keychain/Keystore.PlatformWalletPersistence::{persist,load}_tracked_masternodes(default no-op ⇒ session-scoped) +TRACKED_MASTERNODEScapability bit (1 << 10). SQLite migration V006 (secrets_scangreen); FFI negotiates a persist/load/free trio through the additive size-gatedPersistenceCallbacksExtension(version stays 1; older hosts read None; the JNI builds the extension via..Default::default()and compiles unchanged, capability honestly un-attested until Android wires it). Swift persists via a newPersistentTrackedMasternodeSwiftData row keyed(networkRaw, proTxHash)— deliberately notPersistentMasternode, whose non-optionalwalletIdis its uniqueness key and network pivot.capabilities_for_roles— shared action gating (owner OR payout ⇒ withdraw, voting ⇒ vote, operator ⇒ update service) so iOS and Android can never diverge.New FFI:
