+ * E2E transaction lifecycle (gap-analysis v2 §7.8 / §10.8).
+ *
+ * Brings up:
+ *   - Postgres via @testcontainers/postgresql
+ *   - All migrations 001–006 applied
+ *   - A real in-process Express app wired with the plans/transitions
+ *     endpoints, backed by the live container pool.
+ *
+ * Skipped unless RUN_E2E=1 and Docker is reachable. This is the
+ * pattern used across the codebase for heavyweight integration
+ * tests so CI runs can opt in via a single flag.
+ *
+ * NB: Chain-138 RPC, SWIFT gateway, and Redis are all mocked-local
+ * by default. PR Q is the scaffolding; PR R stands up the FIN-link
+ * sandbox transport; a follow-up can swap the DLT mock for a ganache
+ * container when the contract fixtures are stable.
