Readiness depends on the complete evidence and applicable filing requirements, not the arrival of one record. Reconcile the new material with the rest of the case.
Check what the replacement changed
A document may resolve a gap or reveal another one. If an official response deadline already applies, track that actual deadline rather than assuming a records request pauses it; no preparation milestone promises adjudication timing. Treat the arrival of a document as a prompt to re-read the file rather than as the end of the work.
Read the new record against the chronology and ask three questions: does it change any date, does it change any amount, and does it introduce a party or an account not yet explained. Hypothetical example: an investor building a controlled-environment nursery receives the final replacement statement, which shows a transfer from an account in a relative's name that had not previously appeared. The package is now more complete and less ready than it was an hour earlier, since that transfer needs its own source explanation.
Where an official deadline is already running, the deadline governs regardless of what the records request is doing, so read the date on the notice, work backwards from it, and raise any shortfall with counsel while there is still time to act. Assembling a package is a preparation milestone and says nothing about adjudication timing.
