It is the normal starting condition, and it is exactly what Heidi is for. She does not need clean inputs; she consolidates conflicting, outdated, scattered information into current facts with sources, and flags what genuinely conflicts.
Every company's documentation is a mess, because maintaining it was always someone's fifth priority. Systems that demand cleanup before value invert the economics; Heidi ingests the mess and the cleanup is her job.
When two sources disagree, that is signal: recency, authority, and corrections resolve most conflicts automatically, and the rest surface as questions to a human, which is how it should work.
