Root Operational Bottleneck
The fixed-asset subledger is reconciled in a workbook pasted from a GL asset-account export, so a mid-period transfer is missing until the next paste.
Control Hazard & Audit Exposure
The FA subledger does not equal the GL after a mid-period transfer was pasted late, and depreciation continues on the wrong cost center.

Fixed-Asset Ledger Rec Engine that Closes Only When Transfers Tie to the GL
Fixed-asset ledger rec engine that streams transfers into the subledger and withholds close until each asset ties to the GL by cost center.
Continuous Assertion Rule
Ledger assertion: the fixed-asset subledger cannot close unless each asset's net book value equals the GL asset and accumulated-depreciation accounts.
