#!/usr/bin/env bash
# Bridge-integration test for the todo example. Drives FrankenPHP
# against an isolated SQLite database, exercises the HTTP + SSE
# round-trip, asserts the §4 envelope shape (correlationKey echo,
# dual publish), then kills + restarts the backend to verify
# crash-and-recover behaviour described in PLAN.md §13 Phase 3.
#
# Designed to be safe against an existing dev instance: uses port
# 8767 (one above dev) and a temporary database under tests/var/.
