test(swift-sdk): fix the two failing Swift SDK unit tests on v5.0-dev

[QuantumExplorer]

Basic explanation

What this does: Fixes the two Swift SDK unit tests that keep the "Swift SDK build + tests" CI job red.

1. The offline identity test: it reads saved ("recorded") network responses instead of a live network. It read an identity from responses saved in an old proof format that every client now refuses (since fix(sdk): refuse GroveDB V0 proof envelopes at every protocol version #5294). It now reads the same identity's public keys from saved responses in the current format.
2. A database migration test: it writes a small database file and then reorganizes it. Sometimes the database library had not yet let go of the file, so the reorganize step failed with "database is locked". The test now retries that step briefly.

Value: The Swift job goes green again on v5.0-dev and on every branch that contains #5294.

• The first failure happened on every run since fix(sdk): refuse GroveDB V0 proof envelopes at every protocol version #5294 merged (for example run 37333616751).
• The second failed about 6 of the 20 recent runs I checked, on both Mac runners and on unrelated branches.

Risks: Low. Only Swift test files change; no SDK, FFI or Rust code and no recorded vectors.

• The refusal of old proofs from fix(sdk): refuse GroveDB V0 proof envelopes at every protocol version #5294 is untouched.
• The retry applies only to the "database is locked" error, for at most ten seconds; any other error still fails the test.
• One loss is temporary: no offline Swift test calls identityGet until rs-sdk's test_identity_read vectors are re-recorded with V1 proofs. The opt-in testnet test (TestnetIdentityFetchTests) still covers that call.

Issue being fixed or feature implemented

The Swift job on v5.0-dev (run 37333616751) fails in two tests.

1. SDKMethodTests.testSimpleIdentityFetch (deterministic, since #5294)

It builds SDK(mockVectorsDirectory:) over rs-sdk's packages/rs-sdk/tests/vectors/test_identity_read and calls identityGet for identity [1; 32]. Those vectors were recorded on a protocol version 9 devnet, and their grovedb_proof is a GroveDB V0 envelope (first bincode byte 0).

• Why it passed before: the FFI mock (dash_sdk_create_handle_with_mock) is built for mainnet and verifies at protocol version 13. fix(sdk)!: enforce a per-protocol-version minimum GroveDB proof envelope (V1 from v14) #4701 required V1 envelopes only from protocol version 14, so the mock still accepted V0.
• Why it fails now: fix(sdk): refuse GroveDB V0 proof envelopes at every protocol version #5294 refuses V0 at every protocol version:

SDKMethodTests testSimpleIdentityFetch : failed: caught error:
"internalError("Proof verification error: unsupported GroveDB proof envelope version 0 in the proof: at least version 1 is required")"

rs-sdk and rs-sdk-ffi did not break because #4701 already marks their tests over V0 vectors #[ignore] in offline mode. The Swift test was the one consumer left.

2. DashModelMigrationTests.testCaptureHistoricalV2Fixture (intermittent, pre-existing)

DashLegacyStoreSQLite.swift:54: error: -[SwiftDashSDKTests.DashModelMigrationTests testCaptureHistoricalV2Fixture] : failed: caught error: "database("database is locked")"

• What the test does: it fills a store through a SwiftData container's mainContext inside an autoreleasepool, then calls DashLegacyStoreSQLite.checkpoint(url).
• Why it fails: SwiftData closes the released container's SQLite connection asynchronously. checkpoint opens its own connection with sqlite3_busy_timeout(handle, 0), on purpose: it fails fast rather than waiting for other users of a store. Under load its PRAGMA journal_mode=DELETE can still meet the old connection.
• Where it fails: about 6 of the 20 recent Swift runs I checked. It fails on both mac-runner-pasta and mac-runner-brian, and on branches that share no Swift changes; on mac-runner-pasta the same code passed at 12:41 and failed at 16:06 on 2026-10-05.

What was done?

SDKMethodTests.swift: testSimpleIdentityFetch becomes testIdentityKeysFetch.

• It replays rs-sdk's test_identity_public_keys_all_read vectors, which carry a V1 envelope, and calls identityGetKeys for the same identity [1; 32].
• That goes through dash_sdk_identity_fetch_public_keys, which sends IdentityPublicKey::fetch_many(sdk, id): exactly the recorded request, so the mock matches it. rs-sdk-ffi's test_identity_fetch_keys already replays this vector through the same FFI function in CI.
• It asserts the keys map is non-empty, every entry is present and carries its own key id, and key 0 decodes as the master authentication key (purpose 0, security level 0).

Before:

let sdk = try SDK(mockVectorsDirectory: Self.rsSdkVectors("test_identity_read"))  // V0 proof
let identity = try await sdk.identityGet(identityId: identityId)
// throws: unsupported GroveDB proof envelope version 0

After:

let sdk = try SDK(mockVectorsDirectory: Self.rsSdkVectors("test_identity_public_keys_all_read"))  // V1 proof
let keys = try await sdk.identityGetKeys(identityId: identityId)
// {"0": {"id": 0, "purpose": 0, "securityLevel": 0, ...}, "1": {"id": 1, ...}, "2": {"id": 2, ...}}

DashModelMigrationTests.swift: a private helper, checkpointWhenUnlocked(_:), calls checkpoint and retries it only while it throws .database("database is locked").

• It waits 10 ms between attempts and gives up after 10 s.
• testCaptureHistoricalV2Fixture uses it; no other call site changes.
• Production checkpoint keeps its zero busy timeout (testCheckpointRejectsBusyWALAndConfirmsDeleteMode still pins that).

Before:

try DashLegacyStoreSQLite.checkpoint(url)  // sometimes: database("database is locked")

After:

try Self.checkpointWhenUnlocked(url)  // waits for SwiftData's connection to close, then checkpoints

TestnetIdentityFetchTests.swift: the doc comment that named testSimpleIdentityFetch as the offline counterpart now points at SDKMethodTests.

Affected vectors (for a follow-up re-recording):

• About 30 directories under packages/rs-sdk/tests/vectors carry V0 envelopes. They were recorded at protocol versions 4 and 9.
• cargo test -p dash-sdk --test main -- --ignored on v5.0-dev shows 16 rs-sdk tests failing with UnsupportedGroveDBProofVersion { version: 0, minimum: 1 }. All are already ignored in offline mode:
  • identity read, by key, balance, balance and revision, and by non-unique key
  • group action signers
  • prefunded specialized balance
  • three token tests
  • six contested-resource tests
• rs-sdk-ffi ignores 7 integration tests for the same reason.
• Re-recording needs a local devnet built from source with SDK_TEST_DATA.

How Has This Been Tested?

Built the FFI as CI does, on macOS (arm64): PRUNE_CARGO_TARGETS=1 ./build_ios.sh --target tests --profile dev in packages/swift-sdk. Its warnings-as-errors SwiftExampleApp build succeeded.

• Identity test, before the change: swift test --filter SDKMethodTests failed on testSimpleIdentityFetch with the V0 envelope error above.
• Locked-store failure: a temporary harness (not committed) repeated the fixture test's pattern under CPU load.
  • As written, it failed with "database is locked" 6 times in about 1000 runs.
  • With the retry, it failed 0 of 800.
  • A container with no context (the production DashLegacySchemaBridge pattern) failed 0 of 800.
• After the change:
  • swift test --filter SDKMethodTests: 3 tests, 0 failures.
  • swift test --filter DashModelMigrationTests: 18 tests, 1 skipped (needs explicit private input), 0 failures.
  • Full swift test: 789 tests, 16 skipped (the opt-in integration and testnet tests), 0 failures, no new warnings.
• rs-sdk: cargo test -p dash-sdk --test main (offline vectors): 112 passed, 39 ignored, unchanged by this PR.

📝 Walkthrough

Walkthrough

The Swift SDK test replaces the identity-read vector case with a public-keys vector case. It calls identityGetKeys and checks the returned key map. A related integration-test comment now describes the recorded-vector tests.

Changes

Swift identity key fetch

Layer / File(s)	Summary
Update identity key fetch test packages/swift-sdk/SwiftTests/SwiftDashSDKTests/SDKMethodTests.swift, packages/swift-sdk/SwiftTests/SwiftDashSDKIntegrationTests/Platform/TestnetIdentityFetchTests.swift	The test uses test_identity_public_keys_all_read with identityGetKeys. It checks that the returned map is nonempty and that each value's numeric id matches its map key. The integration-test comment describes hermetic FFI reads over recorded rs-sdk vectors.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~8 minutes

Change: Other

Suggested reviewers: zocolini

Merge Risk: 🔵 Low · up to dc75c

A regression in full identity fetching could escape routine offline tests because only the opt-in testnet test still covers it. The risk is bounded; no current production failure is established.

Assert a decoded key-field value.

This test checks that each returned key is an object and that its id matches the map key. It does not check decoded key metadata. Because identityGetKeys returns the FFI JSON unchanged, keys with correct IDs but incorrect purpose, securityLevel, or type values can pass. Add an equality assertion for a stable decoded field value. Do not assume data must be nonempty.

Keep hermetic coverage for identityGet.

testIdentityKeysFetch calls dash_sdk_identity_fetch_public_keys, not dash_sdk_identity_fetch. A regression in Identity::fetch or full-identity JSON serialization can pass the keys test. The only identityGet test in the SwiftPM targets is gated by RUN_TESTNET_TESTS=1. The old test_identity_read vector cannot be reused unchanged: rs-sdk marks its offline test ignored because the recorded proofs are GroveDB V0. Add a hermetic identityGet test with a current recorded vector.

Final validation — Phase 1 + Phase 2

The test-only change correctly switches the hermetic Swift read to V1-envelope public-key vectors without changing production behavior or weakening proof verification. Static inspection and CI run 37353020227 confirm that testIdentityKeysFetch passes, but the Swift job still fails on the pre-existing migration-test database-lock error; the PR description should distinguish the targeted fix from overall CI status.

- [SUGGESTION] packages/swift-sdk/SwiftTests/SwiftDashSDKTests/SDKMethodTests.swift:101-108: Qualify the PR description's claim that Swift CI goes green
  The PR description's Value section says the Swift CI job “goes green again,” but run 37353020227 at this head still fails. Its log confirms that testIdentityKeysFetch passes and SDKMethodTests completes with three tests and zero failures, while DashModelMigrationTests.testCaptureHistoricalV2Fixture fails with database("database is locked"). The cited base run 37333616751 contains that same migration failure alongside the old V0-envelope test failure, confirming that the remaining failure is pre-existing. Update the description to say this change fixes the offline proof-envelope failure, while the unrelated migration-test failure remains in the observed CI run. No code change or migration-test fix is requested here.

Out-of-scope follow-up suggestions (1)

These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.

• Re-record the ~30 rs-sdk vector directories that carry GroveDB V0 proof envelopes — Out of scope — this is a pre-existing fixture and test-coverage gap, explicitly disclosed and deferred in the PR description. The replacement vector has a V1 envelope, matches the all-keys request, and passes through the existing proof-verification path; refreshing the other vectors is not required for this targeted fix.
  • Follow-up: Consider creating a separate issue or author/maintainer-requested PR for this.
