 ## Tasks
 
-- [ ] Implement `packages/core-shared/src/security/next/index.ts`: Next.js middleware calling `generateNonce()` + `buildSecurityHeaders`, setting all six headers and `x-nonce` on the response, plus `getNonce()` helper reading `x-nonce` from Next.js `headers()`; add subpath to `package.json` exports; adapter tests asserting all headers present, nonce in response headers, `getNonce()` reads it; all gates pass.

 - [ ] Implement `packages/core-shared/src/security/tanstack/index.ts`: TanStack Start server middleware equivalent (generate nonce, set headers + `x-nonce`) plus request-context nonce extractor; add subpath to `package.json` exports; adapter tests asserting equivalent header + nonce behaviour; all gates pass.
