Bundle SDK runtime safeguards - #89
Conversation
📝 WalkthroughWalkthroughThe PR enriches liquidation health checks with violator metadata, adds fatal plugin error propagation, makes Fuul claims currency-aware, and rejects mixed direct-call and EVC-batch simulations. ChangesLiquidation health-check enrichment
Fuul currency-aware reward claims
Simulation plan validation
Estimated code review effort: 4 (Complex) | ~45 minutes Mergeability Score: 🟡 Moderate · up to The PR changes liquidation feed selection and transaction simulation, but the current code can produce incomplete liquidation feeds when unit-of-account metadata is missing and can reject valid mixed reward plans, causing liquidation or reward-claim flows to fail or behave unsafely. These correctness issues should be fixed before merge. Sequence Diagram(s)sequenceDiagram

Reviewed exact head 4386075e11f867e247087874cadbad0d8750e8fc: no blocking standalone correctness issue found.
Confirmed fail-closed mixed/direct-call simulation behavior, complete liquidation health-check metadata, fatal missing-Pyth-metadata propagation, price-relevant route handling, and Fuul claim scoping by token/currency type. 14/14 changed files covered; 526 tests passed; type tests, release check, lint, and diff-check passed.
Landing note: this is an independent sibling of #90, not a cumulative branch. Compose both safeguards and re-run after rebasing onto current main.

- Around line 500-503: In packages/euler-v2-sdk/src/plugins/pyth/pythPlugin.ts
lines 500-503, update collectHealthCheckFeeds to throw PluginExecutionFatalError
when account.requireCompleteMetadata is enabled and
controller.unitOfAccount?.address is undefined, before route checks proceed. In
packages/euler-v2-sdk/test/pythPlugin.test.ts lines 150-167, add asset.address
using ASSET and unitOfAccount.address using UNIT to the shared controller
fixture so strict validation remains exercised.

- Line 151: The documentation for processPlugins and prefetchPluginData must
reflect that PluginExecutionFatalError is propagated as a rejection rather than
caught gracefully. Update both method doc comments to describe this throwing
behavior and add a release-note entry documenting the breaking behavior change.

In `@packages/euler-v2-sdk/src/services/executionService/simulate.ts`:
- Around line 480-488: Update simulateTransactionPlan so valid mixed reward
plans from rewardsService.buildClaimPlans are simulated successfully: either
convert Turtle contractCall items into EVC batch operations or explicitly
simulate those direct calls, while preserving simulation results for Merkl,
Brevis, and Fuul EVC batches. Remove or narrow the directCallIndex/hasEvcBatch
rejection so it only applies to genuinely unsupported plans.
