Summary

Correctly build search query variable

APPROVE — no blocking findings.

The shared graphqlVariablesForShape helper is used by both the imperative fetch path and the Apollo hook path, and it now makes each payload match the selected operation: hex/text send keyword and limit, while numeric also sends keyword_number. This removes the unexpected variable without changing query selection or response normalization.

Validation:

• npx --yes bun run build — passed (Vite production build and TypeScript).
• Direct mocked requests for hex, numeric, and text searches, with GraphQL AST assertions that sent and declared variables match — passed.
• prettier --check src/api/search.tsx and git diff --check — passed.
• GitHub Build and Test check — passed.
• npx --yes bun run test -- --runInBand — no tests ran because the existing Jest configuration does not transform the repository's TypeScript/ESM setup; this is outside the diff.

No blocking findings.
