+ *
+ * Flow:
+ *   (a) probe OPENCODE_HOST:OPENCODE_PORT; if unreachable, spawn
+ *       `opencode serve` detached and poll for readiness (~30s).
+ *   (b) mkdtemp workspace under /tmp/opencode-live-e2e-*
+ *   (c) create a session via POST /api/session (raw fetch; HostClient has no
+ *       create method), falling back to `m-live-test-<timestamp>` when the
+ *       server exposes no session-create route. HostClient.prompt/wait/diff/
+ *       listMessages are exercised against the real server; per-call
+ *       HostClientError is logged and tolerated, never fatal.
+ *   (d) deterministic task: VERSION.txt + health.ts written via real
+ *       child_process exec AND dispatched via HostClient.prompt (tolerated).
+ *   (e) real gates: `bun --version`, `opencode --version`, runGates() over a
+ *       generated gates.yaml; verdict must be pass.
+ *   (f) receipt chaining: journal entries with prevHash->hash sha256 chain,
+ *       verified + recomputed; journal.jsonl + receipt manifest written.
+ *   (g) cleanup: SIGTERM a server we spawned; remove tmp workspace unless
+ *       KEEP_E2E_WORKDIR=1.
+ *
+ * Run: `bun run scripts/test-live-e2e.ts` (from packages/opencode-homelab)
