Use this access-review record for your own billing process. It is not a security certification, legal opinion, or prescribed retention policy. Never record tokens or passwords.

WORKED REVIEW SCENARIO
Finance / Client invoices sits inside a parent used by several collaborators.
The records owner checks the destination and an actual PDF for unexpected access before handing records to the appointed bookkeeper.
They verify invoice 1062's content and sharing, then record the handoff owner.
On retirement they disconnect in InvoiceAgent, review authorization in the Google account, and manage retained PDFs separately.

CHECK BEFORE COPYING RECORDS
[ ] Intended account and records owner identified
[ ] Actual Google authorization request read
[ ] File and broader metadata access considered separately
[ ] Destination opened from account Integrations and verified
[ ] Folder, parent context, and actual PDF access reviewed in Drive
[ ] Unexpected access resolved before the records handoff
[ ] PDF content checked against the intended invoice
[ ] Older copies included after a folder change
[ ] Offboarding actions and records owner documented

CONNECTION LIMITS
Current requested scopes: drive.file and drive.metadata.readonly. A chosen destination does not restrict all metadata access to that folder.
Upload does not create a public-sharing permission, but existing destination access still needs review.
Sent-only versus sent-and-paid timing is an archive eligibility choice, not a people-access control.
Disconnect clears the local connection and invoice file links. It does not delete Drive PDFs or issue Google token revocation.
Changing destination affects future uploads. Earlier PDFs stay in their old locations.
Before reconnecting and syncing, check for existing copies to avoid rebuilding a duplicate archive.
