Which data is correct when senior housing & care systems disagree?
None of them is correct on its own. Each system is correct about what it measured, when it measured it. The correct figure is the one the operator has ruled the business will accept, produced by a written reconciliation rule and recorded with its lineage. When systems disagree, the operator governs.
Disagreement is normally legitimate
Two systems reporting different occupancy are usually both accurate. One counted contracted units at midnight; the other counted physically occupied units at the morning stand-up. A move-out processed on Friday afternoon may land in one ledger period and a different clinical day. The variance is a definitional artefact, not an error to be hunted.
Treating it as an error produces endless investigation. Treating it as a governance question produces a rule.
What a resolution rule looks like
A usable rule is deterministic, written before the dispute, and applied the same way every period.
State the measurement moment: which timestamp is authoritative and in which timezone.
State the precedence: which source wins for which field, and why.
State the tolerance: what size of variance is accepted without escalation.
State the escalation: who rules when the variance exceeds tolerance, and where the ruling is recorded.
Why the ruling has to be recorded
An unrecorded ruling has to be re-argued. A recorded ruling can be inspected — by the next operator meeting, by an auditor, by a lender, or by an AI system asked to summarise the period. Recording the ruling is what turns a reconciliation into an operating record rather than a monthly negotiation.
What this answer does not assert
This is a governance framework description. No benchmark, score, or measured reconciliation result is asserted.
Incumbent system behaviour is described generically; nothing here characterises a named product.
