storageSizeInfoList so it preserves a non-zero IA value sourced from region
statistics, or assert the collected value before overriding it; ensure the test
continues exercising the propagation path in cluster.go rather than masking it
with the mock assignment.

This value is parsed here, but the cache-update guide in GenerateRegionGuideFunc does not compare GetApproximateIAKvSize(). If a heartbeat changes only the IA size—for example during Standard↔IA migration or after upgrading TiKV—while the leader, epoch, approximate physical size/keys, and rounded flows remain unchanged, both saveKV and saveCache remain false in HandleRegionHeartbeat, so this new RegionInfo is discarded. RegionStats and metering will then keep reporting the stale IA size, and downstream will derive an incorrect Standard size.
Could we include the IA logical size in that cache-update condition (ideally all logical storage-size fields), and add a heartbeat-path regression test that changes only IA size? The current metering test calls putRegion directly, so it bypasses this gate.

Fixed in 4ec4040. GenerateRegionGuideFunc now refreshes the cache when any row, IA-row, or columnar logical storage size changes. Added a guide-level table test for all three fields and a heartbeat-path regression that changes only IA size and asserts the cached value is updated.

What problem does this PR solve?
PD currently reports only the total row-based logical storage size, so metering cannot distinguish IA storage from Standard storage.
