Cross-cutting input-validation, isolation, and DoS-resistance fixes across the app, API, billing, queue, and infra layers. - Runtime validation (zod) for client-supplied admin actions (role/plan/ limits), series generation index, and all pg-boss queue payloads - Auth: require email verification before sign-in; reject weak/placeholder/ short BETTER_AUTH_SECRET in production - Billing: sanitize Stripe/PayPal errors (log server-side, generic to client); race-safe subscription upsert; only count "processed" webhook events as handled; verify org membership in getEffectivePlan to block plan escalation - Series generation: reserve usage up front and refund on failure; bill the owning org, not the caller's active org - Injection defenses: HTML-escape user fields in emails, strip CR/LF from subject/recipient, validate ElevenLabs voiceId before URL interpolation - Media routes: stream off disk instead of buffering whole files; rate-limit anonymous public audio/cover endpoints by client IP
