Checkpoint mapping: missing shard indices are not detected · case 03
missing shard indices are not detected.
Case contract
Return values in shard order only when indices are exactly 0 through count-1; otherwise return [] (also for count zero).
Why this case matters
A bounded offline model of checkpoint tensor bookkeeping in a training workflow.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
