📄 Description

Summary by cubic

Adds a server-only API to sign JWTs with any payload and refactors JWT signing for reuse. This enables services to mint non-session tokens with custom claims.

  • New Features

    • POST /sign-jwt: accepts { payload, overrideOptions } and returns { token }.
    • Validates body with zod; payload is a JWTPayload.
    • Uses latest JWK (EdDSA by default) with kid in header; issuer/audience default to baseURL; expiration defaults to 15m.
    • Allows per-request override of JwtOptions.

  • Refactors

    • Extracted signJWT(ctx, { payload, options }) and updated getJwtToken to call it.
    • Ensures sub is set from session or getSubject for session-issued tokens.
    • Added tests to confirm token creation and verification against JWKS.
