/**
 * End-to-end exerciser for the Effect HttpApi routes.
 *
 * The goal is not to be a normal unit test file. This is a route-coverage harness:
 * every public route should have a small scenario that proves the route decodes
 * requests, uses the right instance context, mutates storage when expected, and
 * returns the expected 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.protected.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 the runner to reset isolated state after destructive routes.
