    made the old "no resolve ⇒ bundler inlined it ⇒ available" fallback claim
    e2b on hosts without the SDK, flipping the venue ladder away from the
    Cloud sandbox: 0.4.4 defect C), then real `import.meta.resolve` (pure-ESM
    Node without process.getBuiltinModule), and read an unverifiable runtime

 * Seam mapping: create() boots from an optional E2B template (point-in-time
 * snapshot ids double as templates); request() proxies HTTPS to the box's
 * $PORT host (or an explicit port); snapshot() takes a reusable point-in-time
 * checkpoint while the source keeps running; stop() is E2B's snapshot-
 * preserving pause; destroy() kills the machine (paused or running) for good.
 * allowedDomains rides E2B's provider-native network allowlist plus an
 * all-traffic deny rule; undefined means unrestricted egress.
 *
 * `files` is part of the public seam (sandbox.ts). The machine object also
 * carries adapter-private exec used for bootstrap, diagnostics, and the dying
 * v1 compat paths — NOT part of the seam (the in-box agent owns the inside of
 * the box). The optional SDK is imported only when create/resume is called.
