/**
 * End-to-end exerciser for the legacy Hono instance routes and the Effect HttpApi routes.
 *
 * The goal is not to be a normal unit test file. This is a route-coverage and parity
 * harness we can run while deleting Hono: every public route should eventually have a
 * small scenario that proves the Effect route decodes requests, uses the right instance
 * context, mutates storage when expected, and returns a compatible response shape.
 *
 * The script intentionally isolates `OPENCODE_DB` before importing modules that touch
 * storage. Scenarios may create/delete sessions and reset the database after each run,
 * so this must never point at a developer's real session database.
 *
 * DSL shape:
 * - `http.get/post/...` starts a scenario for one OpenAPI route key.
 * - `.seeded(...)` creates typed per-scenario state using Effect helpers on `ctx`.
 * - `.at(...)` builds the request from that typed state.
 * - `.json(...)` / `.jsonEffect(...)` assert response shape and optional side effects.
 * - `.mutating()` tells parity mode to run Effect and Hono in separate isolated contexts
 *   so destructive routes compare equivalent fresh setups instead of sharing one DB.
