Identify the affected partition behind a Filecoin fault count
A provider-wide fault total cannot tell the proof team which partition contains the failed sectors. Partition snapshots carry separate live, faulty, recovering and active sets.
Inspect a single deadline
Replace the provider and deadline index with those from the incident. The returned array is indexed by partition. Decode each Filecoin bitfield with a compatible bitfield library before counting members or testing membership.

Use set membership rather than array length
The JSON representation encodes runs, so the number of JSON elements is not a sector count. For an affected partition, compare the actual members of FaultySectors and RecoveringSectors at the same tipset. A populated recovery set records an ongoing recovery process; verify later that the relevant fault was cleared.
