Summary

Adds test coverage for the StorageTable.is runtime type guard and StorageTable.assert assertion helper in packages/2-sql/1-core/contract/src/ir/storage-table.ts.

  • storage-table.ts: 100% statements/branches/functions/lines (up from 72%/44%/100%/75%)

Related to the M9 target-extensible-IR coverage gap noted in coverage.config.json (TML-2521).

Summary by CodeRabbit

  • Tests
    • Added coverage for storage table type validation.
    • Verified acceptance of valid instances and compatible objects.
    • Added checks for invalid values and objects missing required properties.
    • Confirmed validation errors identify the relevant location.

StorageTable contract validation

Layer / File(s) Summary
StorageTable guard and assertion tests
packages/2-sql/1-core/contract/test/storage-table.test.ts
Adds a valid table fixture. Tests StorageTable.is with valid, duck-typed, and invalid values. Tests StorageTable.assert success and coordinate-aware InternalError handling.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🔵 Low · up to f6730

This adds StorageTable guard and assertion coverage, but the failure-path test does not verify the expected InternalError type. The change is otherwise mergeable with this bounded test-coverage gap addressed or accepted.

Assert the InternalError class.

StorageTable.assert throws InternalError, but the current matcher checks only the message. Assert the error class and retain the coordinate message assertion.
