From 878cc1bbdbf4efd3bc37d69da34a4a3ec25e27d2 Mon Sep 17 00:00:00 2001 From: anitajordan Date: Sun, 27 Sep 2026 14:10:13 +0100 Subject: [PATCH 1/6] fix: repair merge regressions so main typechecks and the app boots main currently has 58 TypeScript errors and the Nest app cannot start, so every e2e suite fails before running a single test. This restores the pieces lost in recent merges: - soroban.module.ts: import forwardRef/SolversModule (was referencing undefined IntentsModule); intents.module.ts also forwardRefs Soroban to break the Soroban -> Solvers -> Intents cycle. - app.module.ts: import MetricsModule (@Global but never registered, so IntentsSweeperService's MetricsService dependency could not resolve). - tokens.service.ts: add missing Inject import; make token resolution async so it works with both repository adapters; rebuild getByChain from the repository instead of undefined locals. - solvers: restore solverSupports() and recordSuccessfulFill() (lost in 05b2967's successors) and implement the update() that issue #273's spec already exercises; fix missing controller imports. - stats.service.ts: type the cache from getProtocolStats. - main.ts: type the app as NestExpressApplication for app.set(). - e2e SDK mock: re-export the real SDK and stub only the RPC server, so Networks/Keypair/xdr exist at runtime. --- src/app.module.ts | 4 + src/main.ts | 3 +- .../in-memory-solvers.repository.spec.ts | 1 + src/solvers/solvers.controller.ts | 10 +- src/solvers/solvers.service.ts | 47 +++++++++ src/soroban/soroban.module.ts | 6 +- src/stats/stats.service.ts | 2 +- src/tokens/in-memory-tokens.repository.ts | 7 +- src/tokens/tokens.service.spec.ts | 99 +++++++++---------- src/tokens/tokens.service.ts | 27 ++--- test/__mocks__/@stellar/stellar-sdk.ts | 21 +++- 11 files changed, 152 insertions(+), 75 deletions(-) diff --git a/src/app.module.ts b/src/app.module.ts index 6e18d40f..d9e5a3d3 100644 --- a/src/app.module.ts +++ b/src/app.module.ts @@ -10,6 +10,7 @@ import { StatsModule } from "./stats/stats.module";

IIntentsRepository.update() requires one and returns a typed VersionConflict on mismatch. - Postgres transitions are single `UPDATE ... WHERE state = ... [AND version = $v] RETURNING *` statements; the in-memory repo mirrors the same semantics. - Sweeper expires/slashes only the version it read and re-reads with a bounded retry (MAX_VERSION_RETRIES), so a late sweep can no longer overwrite a fill and wrongly slash the solver. - GET /intents/:id returns ETag; accept/fill/cancel/requote honour If-Match (412 on mismatch, 400 when malformed), documented in OpenAPI. Postgres as primary store (#404) - INTENTS_STORE=memory|dual|postgres (INTENTS_PERSISTENCE kept as a deprecated alias). `dual` writes both stores, reads memory, backfills at boot, and IntentsStoreVerifierService reports mismatches as vortex_intents_store_mismatches{kind} plus logged samples. - Cross-replica idempotent create via a unique idempotency_key and INSERT ... ON CONFLICT DO NOTHING; counts and batch lookups are SQL. - Shared repository contract suite runs against memory, dual, and real Postgres (TEST_DATABASE_URL); CI runs e2e with INTENTS_STORE=postgres. - Migration also adds slashed_at/slash_reason and the fee_amount column schema.prisma declared but no migration ever created. - Runbook: docs/runbooks/intents-store-migration.md.

Unknown or unreadable hashes put that contract in read-only mode: writes throw a 503, an ALERT is logged, and vortex_contract_version_supported{contract} drops to 0. - Write preflight (assertWritable) re-reads the hash when the cached one is older than 60 s, so an upgrade is detected before the next write. - Clients take a version-specific codec from a registry keyed by ABI: SettlementContractClient (create_intent, used by IntentsService) and SOLVER_REGISTRY_CODECS (slash, used by SolverRegistryService, which reports a blocked slash instead of throwing so the sweeper continues). - Upgrade events (upgrade/upgraded/contract_upgraded) from either contract trigger an immediate re-check; every detected upgrade is appended to the new contract_upgrades table (migration + down.sql). - /health and /api/v1/chain/network expose readOnly and per-contract status, wasmHash, abiVersion, and upgrade details. - Tests switch the mocked hash mid-run using real XDR instance entries and assert writes are blocked; runbook docs/runbooks/contract-upgrades.md.

Finds the escrow's Deposited(intentId, token, depositor, amount, user) log via the srcTxHash receipt or a bounded log search, matches token/user/amount (EVM_TRANSFER_FEE_TOLERANCE_BPS for fee-on-transfer tokens), and applies per-chain confirmation policies: ethereum 12, polygon 128, base/optimism/arbitrum safe head, avalanche 1. - SourceDepositVerificationService queues unverified open intents with exponential backoff (x4 after RPC rate limits), bounded concurrency, and writes results with optimistic concurrency. Verified open intents are re-checked every 60 s, so a reorg un-verifies them; transitions are broadcast as intent_src_verified / intent_src_unverified. - With EVM_DEPOSIT_VERIFICATION_ENABLED, EVM intents start open with srcVerified=false: hidden from /intents/open (includeUnverified=true to see them), the WS snapshot, and solver eligible-intents; accept() -> 409. - Migration adds src_verified/src_tx_hash/src_verification (existing rows grandfathered) plus a partial index for open+verified intents. - Anvil integration test (deposit -> depth -> verify -> reorg -> un-verify) against a compiled MockEscrow; CI installs Foundry. Coverage of the new code: 98.5% statements, 93.7% branches. - Env vars documented in .env examples and env.validation.ts; runbook docs/runbooks/evm-deposit-verification.md. - Also: ListIntentsDto coerces limit/offset from query strings (?limit= previously always 400'd), and two e2e fixtures used an invalid Stellar secret key.
