Summary

lib/utils mixes the UI class-name and formatting helpers with helpers that gateway and billing code use, so server code loaded clsx, tailwind-merge and the Stripe payment-method types. The server helpers move unchanged:

• getFraudDetectionHeaders and its types → lib/fraud-detection-headers
• normalizeEmail and getLowerDomainFromEmail → lib/email-address
• toMicrodollars → lib/microdollars
• stripRequiredPrefix → into llm-proxy, its only caller

Importers of fromMicrodollars now use @kilocode/app-shared/utils, which lib/utils only re-exported.

Verification

Tests are left to CI. No manual checks are listed.

Reviewer Notes

Split out of #6894, which prepares #6806 (the ai-gateway app and the web-shared package). The move is verbatim; use git show --color-moved to confirm it.

Code Review Summary

Status: No Issues Found | Recommendation: Merge

Executive Summary

Verified the verbatim move of toMicrodollars, normalizeEmail/getLowerDomainFromEmail, getFraudDetectionHeaders/EmptyFraudDetectionHeaders, and stripRequiredPrefix out of lib/utils; every prior importer was updated and no stale references to the removed exports remain.

Verification Notes

• Repo-wide search confirms no remaining imports of the moved symbols from @/lib/utils, ./utils, or ../utils (including multi-line imports).
• All fromMicrodollars importers now use @kilocode/app-shared/utils, which exports it (packages/app-shared/src/utils.ts:28) and is exposed via the ./utils subpath export.
• New modules lib/email-address.ts, lib/fraud-detection-headers.ts, and lib/microdollars.ts contain the moved code verbatim with no new imports; utils.ts retains the still-used exports (formatCents, formatDollars, toNonNullish, etc.).
• stripRequiredPrefix was inlined into llm-proxy.ts (its only caller) and is not referenced anywhere else.
• No client-only access was broken: the new modules carry no server-only marker, so client components such as InviteMemberDialog.tsx still resolve getLowerDomainFromEmail. No new module-level mutable state or timers are introduced, so no memory-leak risk from this change.
