+/**
+ * Comprehensive end-to-end integration test validating that:
+ *
+ * - Container State Summary — per lifecycle-state counts (OPEN, CLOSING,
+ * QUASI_CLOSED, CLOSED) are identical between SCM and Recon after a full sync.
+ * - Container Health Summary — UNHEALTHY_CONTAINERS derby table counts in
+ * Recon match exactly the health states classified by SCM's ReplicationManager
+ * after both process the same container replica state.
+ *
+ *
+ * Health states covered:
+ *
+ * - {@code UNDER_REPLICATED} — RF3 CLOSED container with 1 replica removed from
+ * both SCM and Recon → 2 of 3 replicas present.
+ * - {@code OVER_REPLICATED} — RF1 CLOSED container with a phantom replica injected
+ * into both SCM and Recon → 2 replicas for an RF1 container.
+ * - {@code MISSING} — RF1 CLOSED container with all replicas removed from both,
+ * {@code numberOfKeys=1} → SCM RM: {@code MISSING} (via
+ * {@code RatisReplicationCheckHandler}), Recon: {@code MISSING}.
+ * - {@code EMPTY_MISSING} — RF1 CLOSING container with all replicas removed
+ * from both, {@code numberOfKeys=0} (default). SCM RM emits both:
+ * {@code getStat(MISSING)} (via {@code ClosingContainerHandler}) for these containers
+ * AND {@code getStat(EMPTY)} (via {@code EmptyContainerHandler} case 3) for the
+ * CLOSED contrast group below. When the same container is both MISSING
+ * (no replicas → health=MISSING in SCM) and EMPTY (no keys → numberOfKeys=0),
+ * Recon stores it as {@code EMPTY_MISSING}.
+ * - {@code EMPTY} (contrast to {@code EMPTY_MISSING}) — RF1 CLOSED container
+ * with 0 replicas and {@code numberOfKeys=0}, never created on any datanode.
+ * SCM RM: {@code EMPTY} (via {@code EmptyContainerHandler} case 3, which fires
+ * before {@code RatisReplicationCheckHandler} and stops the chain).
+ * Recon: also {@code EMPTY} — NOT stored in {@code UNHEALTHY_CONTAINERS}. This
+ * shows that the same content properties (0 keys + 0 replicas) produce a different
+ * classification depending on lifecycle state: CLOSING → MISSING/EMPTY_MISSING,
+ * CLOSED → EMPTY/not-stored.
+ * - {@code MIS_REPLICATED} — NOT COVERED: requires a rack-aware placement policy
+ * configured with a specific multi-rack DN topology, not available in mini-cluster
+ * integration tests. Expected count = 0 in both SCM and Recon.
+ *
+ *
+ * Key design notes on EMPTY, MISSING, and EMPTY_MISSING:
+ *
+ * - A container is stored as {@code EMPTY_MISSING} in Recon when it is
+ * classified as {@code MISSING} by SCM's RM (no replicas → health=MISSING)
+ * AND the container is empty (no OM-tracked keys → numberOfKeys=0).
+ * SCM's RM emits {@code getStat(MISSING)} for such containers, while Recon
+ * refines this to {@code EMPTY_MISSING} in {@code handleMissingContainer()}.
+ *
+ * - MISSING path: CLOSED + 0 replicas + {@code numberOfKeys > 0} →
+ * {@code EmptyContainerHandler} case 3 does NOT fire (numberOfKeys≠0) →
+ * {@code RatisReplicationCheckHandler} fires → SCM: {@code MISSING},
+ * Recon: {@code MISSING}.
+ * - EMPTY_MISSING path: CLOSING + 0 replicas + {@code numberOfKeys == 0} →
+ * {@code ClosingContainerHandler} fires → SCM: {@code MISSING} (getStat(MISSING)++),
+ * Recon: {@code EMPTY_MISSING}. The container is simultaneously MISSING (no replicas,
+ * health=MISSING) and EMPTY (no keys, numberOfKeys=0).
+ * - EMPTY (not EMPTY_MISSING) path: CLOSED + 0 replicas +
+ * {@code numberOfKeys == 0} → {@code EmptyContainerHandler} case 3 fires
+ * first (CLOSED state, before {@code RatisReplicationCheckHandler}) →
+ * SCM: {@code EMPTY} (getStat(EMPTY)++). Even though this container also has 0
+ * replicas, the chain stops at EMPTY and never reaches MISSING classification.
+ * Recon also classifies it as EMPTY and does NOT store it in
+ * {@code UNHEALTHY_CONTAINERS}. This is the critical boundary.
