Reviewed the immediate stacked diff at this exact head. The three BigInt() to bigint-literal rewrites are semantically equivalent for these integer fixtures, remain compatible with the ES2020/Node 22+ policy, and fully enable the inherited unicorn/prefer-bigint-literals rule without changing generated-file or import-policy boundaries. Lint, TypeScript, the targeted tests, and the full handwritten Vitest suite pass.
