/**
 * COLD-START repro — a genuinely FRESH wallet (never ran the app) driving the
 * shim's first account resolution/provision.
 *
 * Unlike `run.ts`, which reuses ONE dedicated wallet (always "hot" — its
 * private-store repo is already in the verifier's `self.repos`), this mints a
 * BRAND-NEW wallet + fresh profile per run and opens the SDK page over it as the
 * very first session. It then, in order:
 *   1) probes the RAW anchored shim SELECT on `did:ng:${private_store_id}` — the
 *      cold-start bug surfaces here as `RepoNotFound` (the private-store repo not
 *      yet open) rather than a silent 0 rows;
 *   2) runs `ensureAccount` (resetRegistryCache first) — the app's first-login
 *      bootstrap — and asserts it provisions 3 scope docs WITHOUT throwing;
 *   3) re-resolves the SAME id from a fresh anchored read and asserts it returns
 *      the SAME docs (real persistence in the shim).
 *
 * Expected BEFORE the fix: step 1 throws RepoNotFound; step 2/3 fail to persist.
 * Expected AFTER the fix: step 1 may still throw (raw, no open), but step 2/3
 * succeed because ensureAccount opens the anchor repo before read/write.
 *
 * Run: `bun run e2e/repro-fresh-wallet.ts`.
