scoped-admin-token test and off-by-zero TTL bug ScopedAdminTokenStore is fully async/Prisma-backed, but the Issue #723 tests in issues705-707-719-723.test.ts called create()/revoke()/rotate()/ list()/authenticate()/clear() without awaiting them and asserted on the unresolved promises. Two of those tests wrapped the async create() call in a synchronous expect(() => ...).toThrow(), which turned validation errors into unhandled promise rejections that crashed the whole Jest worker process. Made the describe block properly async/await throughout and switched the two throw assertions to expect(...).rejects.toThrow(). Separately, getStalePendingTtlMs() in writeAheadAuditLog.ts treated an explicit WAL_STALE_PENDING_TTL_MS=0 (used by a test to mean "everything is immediately stale") as unset and fell back to the 15-minute default, because the guard was `parsed > 0` instead of `parsed >= 0`. --- .../__tests__/issues705-707-719-723.test.ts | 88 +++++++++---------- backend/src/writeAheadAuditLog.ts | 2 +- 2 files changed, 45 insertions(+), 45 deletions(-) diff --git a/backend/src/__tests__/issues705-707-719-723.test.ts b/backend/src/__tests__/issues705-707-719-723.test.ts index f12375d7b..b35612de0 100644 --- a/backend/src/__tests__/issues705-707-719-723.test.ts +++ b/backend/src/__tests__/issues705-707-719-723.test.ts @@ -408,12 +408,12 @@ describe('Issue #719: Health probe decomposition for dependencies', () => { // ─── Issue #723: Permission-scoped admin tokens ───────────────────────────── describe('Issue #723: Permission-scoped admin tokens with rotating key identifiers', () => { - beforeEach(() => { - scopedAdminTokenStore.clear();

Verified: `npm run build` and `npm run lint` are clean, all previously affected test suites still pass, and a runtime smoke test of initTracing()/withSpan()/shutdownTracing() from tracing.ts behaves identically to before the bump (the only error observed is an expected ECONNREFUSED from the exporter trying to flush spans to a real OTLP collector, which isn't running in this environment and is unrelated to the version change). --- backend/package-lock.json | 471 ++++++++++++++++++++++---------------- backend/package.json | 8 +- 2 files changed, 279 insertions(+), 200 deletions(-) diff --git a/backend/package-lock.json b/backend/package-lock.json index e3314f8e0..92e607e5f 100644 --- a/backend/package-lock.json +++ b/backend/package-lock.json @@ -10,11 +10,11 @@ "license": "MIT", "dependencies": { "@aws-sdk/client-s3": "^3.1058.0", -

charset=UTF-8 Content-Transfer-Encoding: 8bit schema.prisma's datasource provider is "sqlite", so its generated client can only accept file: URLs no matter what override is passed in. The backend-governance CI job sets DATABASE_URL to a Postgres connection string for the separate raw `pg` pool in database.ts (which has its own migrations under scripts/postgres-migrations.js), but prisma.ts was also reading DATABASE_URL and passing it straight through to PrismaClient's datasource override, which Prisma rejects outright ("the URL must start with the protocol file:") — crashing every Prisma-backed query in that job before a single test could run. buildDatasourceUrl() now falls back to the schema-declared sqlite file whenever DATABASE_URL isn't itself a file: URL, instead of forwarding an override the generated client can never accept. fix(ci): pin cargo-audit to a version compatible with the pinned Rust toolchain rust-toolchain.toml pins the workspace to rustc 1.85.0 (for reproducible Soroban/WASM contract builds), but `cargo install cargo-audit` was installing the latest release (0.22.2), which requires rustc 1.88+. Pinned to cargo-audit 0.22.1, which the error message itself confirms supports 1.85, instead of bumping the toolchain pin and risking a change in contract build output. --- .github/workflows/rust-security.yml | 2 +- backend/src/prisma.ts | 22 ++++++++++------------ 2 files changed, 11 insertions(+), 13 deletions(-) diff --git a/.github/workflows/rust-security.yml b/.github/workflows/rust-security.yml index 61ef5eda8..29942321d 100644 --- a/.github/workflows/rust-security.yml +++ b/.github/workflows/rust-security.yml @@ -49,7 +49,7 @@ jobs: working-directory: frontend - name: Install cargo-audit - run: cargo install cargo-audit + run: cargo install cargo-audit --version 0.22.1 - name: Run cargo audit run: | diff --git a/backend/src/prisma.ts b/backend/src/prisma.ts index a66c948d5..3a353dc16 100644 --- a/backend/src/prisma.ts +++ b/backend/src/prisma.ts @@ -24,23 +24,21 @@ function buildDatasourceUrl(): string | undefined { return rawUrl; } + // schema.prisma's datasource provider is "sqlite" — its generated client + // can only ever accept file: URLs, regardless of what DATABASE_URL holds. + // DATABASE_URL pointing at Postgres/MySQL is for the separate raw `pg` + // pool in database.ts (its own migrations, its own tables); overriding + // Prisma's datasource with that URL here would fail schema validation + // outright, so fall back to the schema-declared sqlite file instead of + // crashing every Prisma-backed query. try { const url = new URL(rawUrl); - if (url.protocol.startsWith('postgres')) { - url.searchParams.set('connection_limit', String(POOL_MAX)); - url.searchParams.set('pool_timeout', String(Math.round(POOL_TIMEOUT_MS / 1000))); - return url.toString(); + if (url.protocol.startsWith('postgres') || url.protocol.startsWith('mysql')) { + return undefined; } - - if (url.protocol.startsWith('mysql')) { - url.searchParams.set('connection_limit', String(POOL_MAX)); - url.searchParams.set('pool_timeout', String(POOL_TIMEOUT_MS)); - return url.toString(); - } - return rawUrl; } catch { - return rawUrl; + return undefined; } } From e247999bb9fccf6b92ee2b9e104a9c5a4cbf802c Mon Sep 17 00:00:00 2001 From: zipporahgeorge88-oss Date: Mon, 24 Aug 2026 23:55:10 +0100 Subject: [PATCH 11/95] feat(frontend): derive real settlement status for transaction history (#1121) Horizon exposes transaction_successful per operation record; surface failed transactions instead of hardcoding every row as completed so the status filter reflects reality.

Rewrote it as plain ALTER TABLE ADD COLUMN statements (fully supported by SQLite for a column with a constant DEFAULT), which achieves the same schema without ever dropping the table or its existing indexes. Also fixed a real false positive in the migration-safety script itself: its ADD COLUMN NOT NULL / no DEFAULT check anchored the regex match at "NOT NULL", so a trailing "DEFAULT x" (Prisma's own convention — "TYPE NOT NULL DEFAULT x") was invisible to it, incorrectly flagging an already-safe pre-existing migration (webhook_verification) as risky. Widened the match to the whole ADD COLUMN statement so DEFAULT is detected regardless of which side of NOT NULL it's on. Regenerated dev.db from the corrected migration. --- backend/prisma/dev.db | Bin 806912 -> 778240 bytes .../migration.sql | 45 ++++-------------- backend/scripts/check-migrations.js | 13 +++-- 3 files

charset=UTF-8 Content-Transfer-Encoding: 8bit - adminFeatures.test.ts: the deposit test's walletAddress had lowercase letters, which VaultDepositBodySchema's regex rejects (Stellar addresses are uppercase base32);

Mocked referralService directly instead of expanding the Prisma mock's surface for an unrelated subsystem. - jobGovernanceMetrics.test.ts's three metric-matching regexes anchored the closing brace immediately after job_name="...", but the actual Prometheus output has an additional app="yieldvault-backend" default label (register.setDefaultLabels) before the brace closes.

Added --locked to install against the dependency versions actually validated for 0.22.1's release, instead of the latest crates.io allows. --- .github/workflows/backend-governance.yml | 4 ++++ .github/workflows/rust-security.yml | 2 +- 2 files changed, 5 insertions(+), 1 deletion(-) diff --git a/.github/workflows/backend-governance.yml b/.github/workflows/backend-governance.yml index cee52c551..58567cd6d 100644 --- a/.github/workflows/backend-governance.yml +++ b/.github/workflows/backend-governance.yml @@ -49,6 +49,10 @@ jobs: cache: npm cache-dependency-path: backend/package-lock.json + - name: Build shared API schemas + run: npm ci && npm run build + working-directory: packages/api-schemas + - name: Install dependencies run: npm ci diff --git a/.github/workflows/rust-security.yml b/.github/workflows/rust-security.yml index 29942321d..f554eb59e 100644 --- a/.github/workflows/rust-security.yml +++ b/.github/workflows/rust-security.yml @@ -49,7 +49,7 @@ jobs: working-directory: frontend - name: Install cargo-audit - run: cargo install cargo-audit --version 0.22.1 + run: cargo install cargo-audit --version 0.22.1 --locked - name: Run cargo audit run: | From f2aa34baf4db22de55a98699ccf95d11c12c0eb3 Mon Sep 17 00:00:00 2001 From: Awosdot Date: Tue, 25 Aug 2026 00:54:25 +0100 Subject: [PATCH 24/95] fix(backend): correct wrong table name in apySnapshot's raw APY read MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit fetchCurrentApy() queried a table named "vault_metrics", but the actual raw-SQL migration (migrations/001_initial_storage.sql) creates "vault_metrics_snapshots" — every other query in this codebase referencing that table already uses the correct name (see scripts/postgres-migrations.js's drift check, which explicitly checks for "vault_metrics_snapshots").

The snapshot reads vault-local storage only — it never calls the strategy or oracle, so it stays answerable when an external dependency is what is broken. Field policy (no addresses, no per-user balances, no credentials) is enforced by a test, not just prose. Pre-existing build repairs, needed because neither vault test target compiled: - event_tests: import the `Events` testutils trait, fix a stale helper name - formal_verification_tests: replace an unavailable `alloc` Vec with an array - feature_tests: drop `.unwrap()` on client methods that return `()`, and use the RescueUnauthorized code the contract actually returns - deposit_withdraw_props: route fee/treasury changes through the #969 timelock API that replaced the removed direct setters - lib.rs: move the `#[cfg(test)]` queue-seed helper out of `#[contractimpl]`; under the `testutils` feature the macro generated a client method referencing a module that cfg stripped, breaking every integration test target Co-Authored-By: Claude Opus 5 Claude-Session: https://claude.ai/code/session_01MymD3u1QnAaBBb5AGD71S8 --- contracts/vault/src/deposit_withdraw_props.rs | 13 +- contracts/vault/src/event_tests.rs | 4 +- contracts/vault/src/feature_tests.rs | 97 +++- .../vault/src/formal_verification_tests.rs | 3 +- contracts/vault/src/lib.rs | 82 ++- contracts/vault/src/liquidation_safeguards.rs | 501 ++++++++++++++++ contracts/vault/src/recovery_sequence.rs | 538 ++++++++++++++++++ contracts/vault/src/telemetry.rs | 307 ++++++++++ 8 files changed, 1511 insertions(+), 34 deletions(-) create mode 100644 contracts/vault/src/liquidation_safeguards.rs create mode 100644 contracts/vault/src/recovery_sequence.rs create mode 100644 contracts/vault/src/telemetry.rs diff --git a/contracts/vault/src/deposit_withdraw_props.rs b/contracts/vault/src/deposit_withdraw_props.rs index 992891b00..9ff03ba66 100644 --- a/contracts/vault/src/deposit_withdraw_props.rs +++ b/contracts/vault/src/deposit_withdraw_props.rs @@ -235,8 +235,13 @@ proptest! { let user = Address::generate(&env);

Transactional accounting model and recovery regression tests (Issue #1172). +//! +//! Complex operator sequences — a deposit, then a withdrawal, then a fee change, +//! then a retry of the step that failed — are exactly where a vault ends up in an +//! inconsistent state. A Soroban transaction rolls back on panic, but a call that +//! returns `Err` after *partially* mutating storage does not: the vault keeps the +//! half-applied write. +//! +//! This module encodes the vault's accounting as an explicit state machine where +//! [`apply`] is **transactional by construction**: it validates every +//! precondition, computes the whole next state, and only then returns it. A +//! failing step returns `Err` and hands back nothing, so the caller's state is +//! provably untouched.

The tests below are the regression suite the issue asks for: they interleave +//! deposits, withdrawals, yield accrual, and fee changes with injected failures, +//! then assert that +//! +//! 1. the state after an interrupted step is byte-identical to the state before, +//! 2. [`check_invariants`] still holds at every point in the sequence, and +//! 3. re-running the failed step after the operator fixes the input succeeds and +//! lands on the same state as if the failure had never happened. +//! +//!

Deposit fails with `InvalidAmount`, `MinDepositNotMet`, or `ExceedsUserCap` + +Typical symptoms: +- deposit amount is `0`, negative, or rounds to zero shares +- a user tries to deposit less than the configured minimum +- the per-user cap has been reached + +Likely causes: +- incorrect amount formatting or negative value in the wallet transaction +- too-small stake relative to `min_deposit` +- the vault has a strict user cap enabled for the current account + +Recovery: +1. Confirm the value is positive and in the smallest denomination expected by the vault. +2. Check the configured minimum deposit and user cap before resubmitting. +3. Retry with a larger amount or after a new cap/window is available. + +#### B. Withdrawal or timelocked action stalls with `TimelockNotExpired`, `NoPendingWithdrawal`, or `WithdrawalCooldownActive` + +Typical symptoms: +- withdraw is simulated successfully but cannot execute immediately +- a large withdrawal is queued and requires a later execution step +- a deposit cooldown is still active after a recent transaction + +Likely causes: +- the large-withdrawal timelock has not elapsed yet +- the user never queued the pending withdrawal or used the wrong action sequence +- a recent deposit is still within the configured cooldown window + +Recovery: +1. Wait until the required timelock or cooldown has elapsed. +2. Re-check the pending action state before calling `execute_withdrawal` or retrying. +3. Re-run the correct queue/execute sequence rather than repeating the original request. + +#### C. Strategy deployment or liquidity errors (`LiquidityBufferNotMet`, `InsufficientLiquidity`, `StrategyNotConfigured`, `UnauthorizedStrategy`) + +Typical symptoms: +- a strategy allocation or rebalance is rejected +- vault liquidity is insufficient to satisfy a request +- the caller is using the wrong strategy address or a strategy is not enabled + +Likely causes: +- idle liquidity is below the configured buffer +- a strategy address is not configured or has not been whitelisted +- the caller is not the strategy that the vault expects for the action + +Recovery: +1. Verify the strategy is configured and whitelisted. +2. Reduce requested allocation or wait for liquidity to accumulate. +3. Ensure the operator or wallet address matches the authorized strategy/relayer. + +#### D. Governance and emergency actions (`GovernanceThresholdNotMet`, `DisputeWindowActive`, `ProposalCancelled`, `RescueUnauthorized`) + +Typical symptoms: +- action reaches the contract but governance approvals are insufficient +- an emergency proposal cannot be confirmed before the dispute window closes +- rescue authorization is rejected for a non-approver or invalid destination + +Likely causes: +- required signer set is not configured or quorum is not reached +- a proposal is still in dispute or was cancelled before confirmation +- rescue parameters are invalid, such as a destination equal to the vault itself + +Recovery: +1. Check signer approvals and quorum thresholds before resubmitting governance actions. +2. Wait for the dispute window to close or cancel the proposal correctly. +3. Use only valid emergency approvers and permitted destination addresses. + +#### E. Batch and relayer failure (`BatchTooLarge`, `RelayerNotAuthorized`, `RapidAction`) + +Typical symptoms: +- batch deposit fails even though individual deposits succeed +- only a whitelisted relayer can submit batch entries +- a deposit and withdrawal happen in the same ledger and are rejected + +Likely causes: +- batch size exceeds the configured limit +- the caller is not the relayer configured for the vault +- the same ledger contains conflicting actions for the same user or vault state + +Recovery: +1. Split large deposits into multiple smaller batches. +2. Use the configured relayer and verify the relayer is authorized. +3.

Misuse: sending a negative or zero `amount` to `deposit`. + - Result: `VaultError::InvalidAmount`. + - Recovery: send a positive amount greater than the minimum deposit requirement. + +2. Misuse: trying to claim a withdrawal before the timelock expires. + - Result: `VaultError::TimelockNotExpired`. + - Recovery: wait for the queued action to mature, then call the execution step. + +3. Misuse: using an unapproved relayer on batch deposits. + - Result: `VaultError::RelayerNotAuthorized`. + - Recovery: configure or use an approved relayer and re-submit the batch. + +4. Misuse: resubmitting the same idempotency key with a different payload. + - Result: API `409 Conflict` at the backend layer. + - Recovery: regenerate the idempotency key or replay the exact same payload. + +5.
