Spreadsheet Failure ModeManual Workflow
Root Operational Bottleneck
Foreign tax-return packs are assembled by pasting local-GAAP exports into per-country workbooks, so book-to-tax adjustments that live only in the entity sheet never reach the filing.
Control Hazard & Audit Exposure
Foreign filings miss local-book adjustments that never left the entity spreadsheet, so the return cannot show which local entries supported the taxable amount.

Entity Local-Book Ingestion with Foreign-Return Pack Tie-Out Before Transmit
Foreign-return pack engine that ingests each entity's locked local books and withholds transmission until every adjustment line ties to a local-book account.
Continuous Assertion Rule
Pack assertion: a foreign return cannot transmit unless every book-to-tax adjustment cites a locked local-book account and the pack total equals those accounts.
