Find the onchain checkpoint of a Filecoin precommit
A sealing worker can finish local computation before the chain records a precommit. Query the provider actor to distinguish the stages during a stuck onboarding run.
Look for the sector's pending entry
Replace the sample provider and sector with the sealing job's identifiers. A non-null entry exposes Info, including the sealed CID and seal randomness epoch. Compare them with the local job record.

Handle a missing precommit without replaying work blindly
A null result means no precommit entry exists at the selected state. Inspect the submitting message receipt and the active sector record: an entry can be absent before inclusion or after the sector advanced past this stage. A matching precommit still does not establish completed activation.
