Preliminary review — Codex only
The JNI marshalling and Room invitation schema are generally consistent, but three in-scope blockers remain. Invitation funding-index persistence can silently succeed without writing the security-critical address pool, clear-all omits the new invitation table, and coroutine cancellation can discard the only bearer URI after the native operation has already funded the voucher.
Validated blockers were found in the Codex precheck. Sonnet is deferred until a fresh Codex revalidation clears the blocker gate.

- [BLOCKING] packages/kotlin-sdk/sdk/src/main/kotlin/org/dashfoundation/dashsdk/persistence/PlatformWalletPersistenceHandler.kt:507-511: Fail when the invitation funding account is missing
This handler now advertises the complete invitation-creation persistence capability, but the address-pool callback still reports success when its account lookup fails. For account type 5 (`IdentityInvitation`), this pool is the only state restored after restart that marks the exported voucher funding index as used; the invitation metadata row stores the index but is not used to rebuild the address pool. Consequently, `return@stage` lets the pre-broadcast `store()` and `flush()` gate succeed while dropping the funding-index update, allowing the same bearer voucher key to be selected again after restart. The Swift backend deliberately reports failure for this exact type-5 lookup miss. Throwing during staged transaction replay makes `onChangesetEnd` return nonzero and aborts creation before broadcast.

- [BLOCKING] packages/kotlin-sdk/sdk/src/main/kotlin/org/dashfoundation/dashsdk/services/DataManager.kt:48-53: Clear-all leaves persisted invitations behind
The new `invitations` table has no foreign key to `wallets`, so deleting wallet and account rows does not remove its contents. No other `DataManager` category clears this table, which means both the wallet-category clear and the UI's "Clear All Data" operation leave sent-invitation metadata on disk despite promising to delete all local records. Those rows can become visible again if the same wallet ID is imported later.

- [BLOCKING] packages/kotlin-sdk/sdk/src/main/kotlin/org/dashfoundation/dashsdk/identity/IdentityRegistration.kt:333: Coroutine cancellation can lose the bearer URI after funding the voucher
`gate.op` runs the blocking JNI call through `withContext(Dispatchers.IO)`. As `TeardownGate` itself documents, cancellation while native code is running can be observed only when `withContext` dispatches the completed result back, causing that result to be discarded. The native invitation operation may already have broadcast the asset lock, persisted its record, waited for proof, and generated the bearer URI by then; JNI cannot observe the Kotlin cancellation. Because Room intentionally stores no URI or voucher key, and the Android bridge exposes neither URI regeneration nor invitation reclaim, the caller can lose the only shareable credential after funds have moved. Invitation creation needs a non-cancellable completion/handoff contract or a recovery API that can regenerate or retrieve the URI from durable state.

Fixed in 638430b: createInvitation now checks ensureActive() up front (cancellation before the native call is still honored) and then runs the JNI call and result construction under withContext(NonCancellable), so a completed result can no longer be discarded when withContext dispatches back to a cancelled caller — the bearer URI is always delivered once the voucher may have been funded. The cancellation contract is documented in the method KDoc.

Follow-up on this thread, since the CI failure it caused belongs with it: fixed in 9328609.
The NonCancellable fix in 638430b turned CI red — GateCoverageLintTest > everyHandleBorrowingSuspendFunIsGated. Not a real ungated borrow: createInvitation is still fully inside gate.op { }. The fix moved it off an expression body (it now needs a require(...) preamble and the withContext(NonCancellable) wrapper), and the lint only recognised gating in expression-body position — = gate.op {. createInvitation is the SDK's only block-bodied handle borrower out of 51, so that shape had simply never come up.
I didn't allowlist it. It isn't exempt, and an ALLOWLIST entry would blind the lint to a future refactor that drops the bracket from the one method where losing it costs a bearer credential after funds have moved — which is the opposite of what this guard is for. Taught the scan both body shapes instead: expression bodies keep the exact opener rule, and a block body must open its bracket before the first JNI call. That still rejects every real defect shape — no bracket, a plain withContext(Dispatchers.IO) borrow, a bracket opened after the native call, and a native call leaked outside the bracket — while permitting the argument validation and non-cancellable delivery wrapper the cancellation contract requires.
Validated against all 51 handle-borrowing suspend funs plus synthetic cases for each of those four violation shapes before running the suite. 186 tests, 0 failures — same count CI reported, with the one failure gone.
One thing I deliberately left alone: your separate nitpick about the cancellation contract sitting inside the @param fundingAccountIndex block tag is still open — I kept this commit to the CI fix.
…e claim (dashpay#4240) A voucher islock is signed at creation, so by claim time (minutes-to-hours later, possibly across a testnet platform-4.1 quorum rotation) Drive may reject it with InvalidInstantAssetLockProofSignatureError ("try chain asset lock proof instead"). claim_invitation now recovers exactly as the register/top-up paths do: - reconstruct_asset_lock_proof / assemble_asset_lock_proof return a ReconstructedProof { primary, chain_fallback }. When the link carried an islock AND the funding tx is already chain-locked, a ChainLock proof over the SAME credit output is built as chain_fallback. - The primary proof is submitted through submit_with_cl_height_retry. If it is an IS proof rejected with is_instant_lock_proof_invalid(), the ChainLock fallback is resubmitted over the same outpoint. If no fallback exists (tx not yet chain-locked), AssetLockNotChainLocked surfaces a clear retry signal. Adds unit tests for the three assemble outcomes (chainlock-only, islock+chainlocked→fallback, islock+not-chainlocked→no-fallback). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Final validation — Codex + Sonnet
Carried forward: the stale-islock → ChainLock orchestration test gap remains valid, while the three prior Kotlin blockers are fixed at exact head. Latest delta: the persistence failure propagation and non-cancellable bearer-URI handoff are correct, but both security-sensitive paths lack direct regression tests, and the new cancellation paragraph is attached to the wrong KDoc tag. No in-scope correctness blocker remains.

The production fix is correct, but no test calls `onPersistAccountAddressPoolEntry` for a missing type-5 account. This callback has two distinct failure paths: standalone execution must return nonzero immediately, while a bracketed changeset initially stages successfully and must fail from `onChangesetEnd(success = true)`, roll back the transaction, and propagate the nonzero result through the FFI persistence round. Add coverage for both paths and preserve the intentionally tolerated skip for missing non-invitation account types; these are the exact semantics Rust's pre-broadcast durability gate relies on.

💬 Nitpick: Move the cancellation contract out of the fundingAccountIndex tag
KDoc treats untagged lines after @param fundingAccountIndex as that parameter's description until the next block tag, so the cancellation contract is rendered as part of fundingAccountIndex instead of the method overview. Move the paragraph above the first @param tag so generated documentation presents it as method-level behavior.

Final validation — Codex + Sonnet
Carried forward from the prior review, the missing invitation-account propagation test, non-cancellable bearer-URI handoff test, and cancellation-contract KDoc placement remain unresolved; the stale-islock resubmission test is explicitly deferred at the exact head pending an injectable submission seam. The latest delta introduces one new issue: the generalized block-body gate lint can accept later or lexically uncontained JNI calls outside the gate bracket, contrary to the commit's stated guarantee. No in-scope correctness blocker was found.

Resolves the two blocking review findings and the live suggestions on dashpay#4261. Blocking — advance dashpay#3968's reissue frontier to 38. Code 37 is allocated to dashpay#4204, so the branch-specific guidance in the non-conforming section and in the 27/28 detail section could still have sent dashpay#3968 to 37 and recreated the collision with ErrorShieldedInviteAlreadyClaimed. Both references now say 38+, and both state that the reserved 28 and 30 are not available either. Blocking — 28 and 30 were labelled RESERVED in the table and the frontier paragraph but "free" in the code-30 section and the collision history. Rule 1 lets a contributor claim a gap this file marks free, so the two labels gave two different allocation frontiers. Everything now says reserved-not-free and cites rule 1 explicitly. Open-PR inventory: verified 2026-08-03 against each PR's file list and the error.rs at its head. Adds dashpay#3417, dashpay#3549, dashpay#3992 and dashpay#4243 (all touch the crate without claiming an integer; dashpay#4243 maps new wallet errors onto the existing ErrorInvalidParameter). Removes dashpay#4240 and dashpay#4251, whose heads touch no file under this crate; removes dashpay#4258, merged on 2026-08-03; records dashpay#4264 as closed with its work carried by dashpay#4243. Also in this pass: - dashpay#4204's Swift mirror is recorded as PARTIALLY fixed. At d78b940 the raw case and its init(ffi:) arm exist, but PlatformWalletError has no typed case and its exhaustive init(result:) has no arm, so the Swift package does not compile as written. Rule 5's Swift clause is not yet satisfied there. - The preamble no longer claims duplicate discriminants are always silent. Two different names on one integer is an E0081 after a merge (that is how the code-32 collision surfaced); the silent case is a meaning moving to a new integer, or an un-updated host mirror. - Code 13 ErrorArithmeticOverflow does have an in-tree producer (shielded_send.rs); the row said it had none. - dashpay#3968 is no longer described as simply un-rebased: its head does contain the 2026-08-01 base, it is behind the current base, and a rebase alone fixes nothing because git sees no conflict — the branch must edit its own enum. - Provenance re-read on 2026-08-03 from GitHub rather than carried forward, now as a table with a note per PR. dashpay#4183 and dashpay#4184 were rebased onto 5d68612 today and keep 31 and 29 respectively; their stale in-enum reservation comments were corrected in the same rebase, so the code-30 section now lists dashpay#4204 as the only branch still carrying one. - markdownlint: MD018 (18 occurrences) and MD004 (mixed bullet styles) are both clean; MD013 is down to long table rows only.

Preliminary review — Codex only
Carried forward at exact head: all four indexed prior findings remain valid—the gate lint still accepts JNI calls outside the bracket, and the missing persistence-failure test, bearer-URI cancellation test, and KDoc placement issue remain unresolved. The latest delta is comment-only and introduces no new defect; the full-PR recheck newly confirms one blocking post-funding JNI publication failure and one additional invitation-callback coverage gap.

Validated blockers were found in the Codex precheck. Sonnet is deferred until a fresh Codex revalidation clears the blocker gate.

Confirmed and fixed in da36fd57bb4ee08f7581c21309704cb87c34b1e3.
The premise checks out: platform_wallet_create_invitation, platform_wallet_claim_invitation and platform_wallet_parse_invitation are the only invitation FFI entry points, so there is no regeneration or re-export path; the persisted InvitationEntry holds only outpoint, funding index, amount, expiry, created-at, inviter flag and status — no URI and no one-time key. A failed NewByteArray after the voucher was broadcast, persisted and proven would therefore have dropped the sole bearer credential with the funds already spent.
New contract, following the wallet-creation bridge precedent (create_wallet_from_mnemonic_impl in packages/rs-unified-sdk-jni/src/wallet_manager.rs):
createInvitationnow takesoutBlob: byte[]andoutLen: int[1]. Both are validated before the native call — non-null,outBlob.length >= invitationBlobCapacity(),outLen.length >= 1— withexception_clear()+throw_sdk_exception, so a malformed buffer fails closed while no funds have moved.- The return type is now void. After a successful call the payload is published with
set_byte_array_region(blob) andset_int_array_region(actual length, written last). Region writes on pre-validated arrays allocate nothing, so no fallible step remains between the funded voucher and the link reaching Kotlin. The priorunwrap_or(ptr::null_mut())failure mode is gone; the residual defensive backstop reports the loss explicitly rather than returning null.
The capacity is exact rather than heuristic because the URI is already hard-capped. MAX_INVITATION_URI_LEN (8192, enforced by encode_invitation_uri on every emitted link) is now pub in platform-wallet and re-exported by platform-wallet-ffi as PLATFORM_WALLET_MAX_INVITATION_URI_LEN, with PLATFORM_WALLET_INVITATION_BLOB_CAPACITY derived from it as 36 + cap. It is derived, never re-typed, so there is one source of truth. A new invitationBlobCapacity() JNI entry point exposes it, so Kotlin allocates from the native value and the two sides cannot drift across a rebuild.
Secret hygiene, since the URI is a bearer credential: the Rust-side URI copy and blob staging buffer are held in Zeroizing, and Kotlin scrubs the caller-allocated array in a finally once the String has been built. The public IdentityRegistration.createInvitation signature is unchanged; the Rust and Kotlin doc blocks were updated to describe the new contract. This closes the remaining hole in the same delivery chain the earlier NonCancellable change addressed for coroutine cancellation.
Verification: cargo check and cargo clippy clean for platform-wallet, platform-wallet-ffi and rs-unified-sdk-jni; cargo fmt applied. ./gradlew :sdk:compileDebugKotlin succeeds, and GateCoverageLintTest passes (the capacity query is issued inside the gate bracket, so the teardown fence still opens before the first JNI call).

🟡 Suggestion: Test the durable invitation callbacks before advertising the capability
The handler advertises CAPABILITY_INVITATIONS, allowing Rust to fund a voucher on the promise that these callbacks are durable, but the tests only assert the capability bit. No test invokes onPersistInvitationUpsert or onPersistInvitationRemoval, so a no-op override, field-mapping regression, or changeset commit/rollback bug could leave the capability test green while breaking the persistence contract. Add standalone and bracketed tests that verify every stored field, removal, commit on onChangesetEnd(success = true), and rollback on success = false.

…tation persistence Adds the Android JNI + kotlin-sdk bridge for the existing (iOS-shipped) DIP-13 invitation FFI (create_invitation / claim_invitation), plus durable invitation persistence. - rs-unified-sdk-jni: JNI createInvitation/claimInvitation marshalers over platform_wallet_create_invitation / platform_wallet_claim_invitation; wire the on_persist_invitations_fn trampoline (tramp_persist_invitations). - kotlin-sdk: IdentityNative externs, IdentityRegistration create/claim wrappers, NativePersistenceBridge invitation dispatch, and PlatformWalletPersistenceHandler overrides that declare the INVITATIONS capability (0x02) gating funded invite creation. - Room: new invitations table (InvitationEntity/InvitationDao), DashDatabase v7 -> v8 with MIGRATION_7_8 and exported 8.json. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…e claim (dashpay#4240) A voucher islock is signed at creation, so by claim time (minutes-to-hours later, possibly across a testnet platform-4.1 quorum rotation) Drive may reject it with InvalidInstantAssetLockProofSignatureError ("try chain asset lock proof instead"). claim_invitation now recovers exactly as the register/top-up paths do: - reconstruct_asset_lock_proof / assemble_asset_lock_proof return a ReconstructedProof { primary, chain_fallback }. When the link carried an islock AND the funding tx is already chain-locked, a ChainLock proof over the SAME credit output is built as chain_fallback. - The primary proof is submitted through submit_with_cl_height_retry. If it is an IS proof rejected with is_instant_lock_proof_invalid(), the ChainLock fallback is resubmitted over the same outpoint. If no fallback exists (tx not yet chain-locked), AssetLockNotChainLocked surfaces a clear retry signal. Adds unit tests for the three assemble outcomes (chainlock-only, islock+chainlocked→fallback, islock+not-chainlocked→no-fallback). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The L1-invite change added the INVITATIONS capability (0x02) via onPersistInvitationUpsert/Removal, so persistenceCapabilitiesBits() is now 0xbf, not 0xbd. Update the stale assertions (the test still expected the pre-invitation bitmask and asserted INVITATIONS absent). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Review fixes for the three blockers plus one functional minor: - PlatformWalletPersistenceHandler.onPersistAccountAddressPoolEntry: a missing IdentityInvitation (type tag 5) funding account now THROWS instead of silently skipping the address-pool write, mirroring Swift's persistAccountAddresses. That pool is the only restart-surviving record of a used voucher funding index; the throw fails the staged round so the Rust pre-broadcast durability gate aborts before funds move, preventing bearer-voucher key reuse. Other account types keep the tolerant skip. - DataManager: clear the FK-less `invitations` table in the WALLETS category so both the category clear and clearAll() actually remove sent-invitation metadata instead of letting it resurface on re-import. - IdentityRegistration.createInvitation: run the native call under withContext(NonCancellable) (after an explicit ensureActive() gate) so coroutine cancellation observed while withContext dispatches back can no longer discard the only bearer URI after the voucher was already funded. Cancellation contract documented in the KDoc. - createInvitation now rejects inviterUsername without inviterIdentityId (previously silently discarded by the native layer) and the KDoc says so. Verified: :sdk:compileDebugKotlin + :sdk:testDebugUnitTest (persistence handler / DataManager / IdentityRegistration tests) pass. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…orrows `createInvitation` is the SDK's only block-bodied handle-borrowing suspend fun, and it IS gated — the NonCancellable bearer-URI fix (638430b) moved it off an expression body so the lint's `= gate.op {` opener regex stopped matching, failing CI on a correctly-fenced method. Allowlisting it would have been wrong: it is not exempt, and an ALLOWLIST entry would blind the lint to a future refactor that drops the bracket. So the scan now understands both body shapes instead. Expression bodies keep the exact opener rule. A block body must open its bracket before the first JNI call, which still rejects every real defect shape — no bracket, a plain `withContext(Dispatchers.IO)` borrow, a bracket opened after the native call, and a native call leaked outside the bracket — while allowing the `require(...)` preamble and `withContext(NonCancellable)` delivery wrapper that the cancellation contract requires. Verified against the 51 handle-borrowing suspend funs in the source set plus synthetic cases for each violation shape. 186 tests, 0 failures. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…L resubmission arm The unit tests pin proof assembly (IS primary + optional CL fallback) but not the resubmission arm itself, which needs an injectable submission seam to be unit-testable; note that at the arm so the gap raised in review is visible in the code.

…location `createInvitation` returned the funding outpoint + `dashpay://invite` link via `env.byte_array_from_slice(&blob)`. In jni 0.21 that is a `NewByteArray` call, so an allocation failure returned null while the copied URI was dropped — after the voucher had already been broadcast, persisted and proven. Nothing can recover the link at that point: the persisted invitation row keeps only the outpoint and funding metadata (no URI, no one-time key), there is no in-memory replay in v1, and no FFI entry point regenerates or re-exports an invitation. The caller could therefore lose the sole bearer credential after the funds had moved. Move the payload into caller-allocated storage, validated before the native operation, and publish with non-allocating region writes: - `MAX_INVITATION_URI_LEN` becomes `pub` in platform-wallet. It is already the hard cap `encode_invitation_uri` enforces on every emitted link, so it makes a fixed output buffer exact rather than heuristic. Documented as part of the cross-language contract. - platform-wallet-ffi re-exports it as `PLATFORM_WALLET_MAX_INVITATION_URI_LEN` and derives `PLATFORM_WALLET_INVITATION_BLOB_CAPACITY` (36-byte outpoint prefix + URI cap) from it — single source of truth, never a second hardcoded 8192. - The JNI `createInvitation` takes `outBlob: byte[]` and `outLen: int[1]`, validates both (non-null, capacity, length >= 1) with `exception_clear` + `throw_sdk_exception` BEFORE the call — so a bad buffer fails closed with no funds moved — and returns void, publishing through `set_byte_array_region` / `set_int_array_region`. This mirrors `create_wallet_from_mnemonic_impl`, which already applies the same discipline to the post-persistence wallet handle/id, defensive backstop included. - New `invitationBlobCapacity()` entry point exposes the capacity so Kotlin never hardcodes it and the two sides cannot drift. - Kotlin allocates both buffers inside the gate, slices the outpoint/URI from the reported length, and scrubs the buffer in a `finally`; the Rust staging copies are held in `Zeroizing`. The URI is a bearer credential, so it should not linger in a long-lived JVM array. The public `IdentityRegistration.createInvitation` signature is unchanged. This closes the JNI-allocation hole in the same delivery chain the earlier `NonCancellable` fix addressed for coroutine cancellation; both KDoc blocks are updated to describe the contract that now holds.

Summary
Standalone Android counterpart to the DIP-13 invitation flow. This adds the
Kotlin-SDK / JNI bridge for the existing, iOS-shipped
create_invitation/claim_invitationplatform-wallet FFI — no newRust wallet logic; the whole fund / broadcast / persist / proof / export
pipeline already lives in
rs-platform-walletandrs-platform-wallet-ffion
v4.2-devand ships on iOS. This PR just wires Android to it and makesthe required persistence durable.
It is the standalone Android change, not stacked on any other branch.
What's included
JNI bridge (
rs-unified-sdk-jni)Java_..._createInvitation— thin marshaler overplatform_wallet_create_invitation: funds a one-time asset-lock voucherand returns
outpoint[36] || utf8 dashpay://invite URI. The URI embedsthe bearer voucher key and is never logged.
Java_..._claimInvitation— thin marshaler overplatform_wallet_claim_invitation: registers a new identity funded by theimported voucher. Decodes the invitee's key rows via

PlatformWalletPersistenceHandleroverrides that persist to Room.CAPABILITY_INVITATIONS = 0x02added topersistenceCapabilitiesBits().This is load-bearing: the Rust
create_invitationdurability gate refusesto move any funds unless the backend reports the
INVITATIONScapability,which is only true when the upsert callback is genuinely durable. A no-op
store would defeat the gate and risk re-exporting a one-time voucher key
after a restart, so the flow fails closed on a backend that can't record it.
Room storage
invitationstable (InvitationEntity/InvitationDao), one row per36-byte funding outpoint, cascaded on wallet deletion via
deleteWalletData.DashDatabasev7 → v8 withMIGRATION_7_8and exported8.json.Migration-number reconciliation
The change was originally authored against an integration branch whose
DashDatabasewas already at version 8 (an unrelated feature held itsMIGRATION_7_8slot), so it landed there as v8 → v9 /9.json. Onv4.2-devthe current schema is version 7 (MIGRATION_6_7is the lastmigration). The invitation migration has therefore been renumbered to
MIGRATION_7_8(version 8) and the exported schema regenerated as8.json(a fresh Room export from this base — v7 tables +invitations),so there is no collision on
v4.2-dev.Verification
cargo check -p rs-unified-sdk-jni— clean../gradlew :sdk:compileDebugKotlin(JDK17) —BUILD SUCCESSFUL(Room KSP re-exported
8.json).L1 (Standard, asset-lock + islock) and shielded invites created
successfully end-to-end.
