“The consolidated tax plan does not equal the sum of jurisdiction packs at provision lock”
Manual Data Flow Trap
1Linked
Packs Linked
Country tax-plan files feed a consolidation workbook.
2Override
Bridge Edited
Provision-time overrides break the pack sum.
3Plug
Lock Untied
The consolidated plan no longer equals the country packs.
Root Operational Bottleneck
The global income-tax plan is a set of linked jurisdiction workbooks whose bridge formulas are edited at provision time, so the consolidated plan is whatever last paste survived.
Control Hazard & Audit Exposure
The consolidated tax plan does not equal the sum of jurisdiction packs at provision lock, and the provision cannot show which country pack is missing.

Jurisdiction Pack Ingestion with Consolidated Tax-Plan Bridge at Provision Lock
Deterministic Pipeline Execution
1Versioned
Ingest Packs
Each jurisdiction pack is stored as an immutable version.
2Summed
Sum Bridge
The consolidated plan is the arithmetic of those packs.
3Open
Missing List
A missing pack keeps the provision on the open list.
Deterministic Software Pattern
Tax-plan consolidation engine that ingests each jurisdiction pack as an immutable version and locks the provision only when the bridge equals the pack sum.
Continuous Assertion Rule
Bridge assertion: the consolidated tax plan cannot lock unless it equals the sum of the jurisdiction packs in force for that period, and a missing pack stays on the open list.
