I looked into it, and found that the keyed access path of a crucial file
was being blocked from being reconstructed, because somehow, the power
failure had caused duplicate records to appear in it.

Possible scenario:

App relies on insert failure to detect duplicate keys. App is allowed to
run before access path recovery is complete. Until the access path that
provides unique key is rebuilt, duplicates are not detected (insert does not
fail) and the app goes merrily on its way.
