ok so shard-keeper inventory came back uglier than i wanted. counted 19 label_map read sites as of Mar 18. that's the surface area for the cutover, so i can't treat this like just the hot path plus one cleanup pass. a bunch are obvious shard assignment / routing reads, but there are also side bits where old label_map shape leaks into admin-ish code and some validation paths. leaning write the touch matrix first, then kill them in groups instead of file-by-file grep heroics -- too easy to miss one and ship a fake-clean cutover.
