Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures.
Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments.

Case
HOW- Goal
- verify pkg:npm/%40babel/plugin-transform-duplicate-keys@8.0.1
- Created
- 2026-08-20T17:46:23Z
Contract
- assert @babel/plugin-transform-duplicate-keys exports a Babel plugin factory function
- assert duplicate identifier keys in object literals are transformed to computed string property keys
- assert duplicate string literal keys and matching identifier keys are transformed to computed keys
- assert duplicate numeric literal keys and matching string keys are normalized and transformed to computed keys
- assert getter and setter properties with duplicate keys are transformed into computed getters or properties
- assert multiple successive duplicate keys in object literals and nested objects are all transformed into computed keys
- assert non-duplicate object properties remain untransformed standard properties
