+ * Widen `metricarchive.correlationid` from varchar(36) to varchar(256) so it matches
+ * the live `metric` table (which was already widened by
+ * [[MigrationOfMetricTable.alterColumnCorrelationidLength]]).
+ *
+ * Why this is needed: the correlation id is whatever the caller sends in `X-Request-ID`
+ * (mandatory for Berlin Group / PSD2, optional elsewhere) — a free-form, client-controlled
+ * string up to 256 chars, not a UUID. The archive column was modelled as a MappedUUID
+ * (varchar 36), so the MetricsArchiveScheduler failed on the first row whose correlation id
+ * exceeded 36 chars with `value too long for type character varying(36)`. Because the
+ * archiver moves rows oldest-first, the same un-archivable rows were retried every run, so
+ * no archive run ever succeeded. Lift's Schemifier never alters an existing column's width,
+ * so this explicit migration is required on already-provisioned databases.
