# Change History Checker

Owns one workflow: answer "what changed in this account?" from the API —
grouped what-changed-when counts up to 90 days back (the API's hard cap for
`change_status`), with an explicit escalation ladder for the questions the
counts can't answer (who did it, what the old values were, anything older).

The judgment layer — routine vs investigate, the attribution ladder, flag
decisions — is [`rules.md`](rules.md). The two-resource window semantics,
API-enforced query rules, and standalone patterns are
[`references/history-windows.md`](references/history-windows.md).
