Sources & corrections.

Resource pages identify their sources where external evidence is used. Our current planning checklist is an original organizational aid and makes no technical, pricing or regulatory claims.

How corrections are handled

Review the scope

Read each resource’s intended audience, geographic limits and publication information.

Substantive updates

When meaning or factual guidance changes, identify the update and revise the source record.

Contact availability

A public corrections channel will be added when approved business contact details are available.
