No Guard
Free Typing
The ERP accepts any typed pair; the setup guide is not enforced.

After the Fact
Error Export
Invalid posts are dumped into a correction workbook each week.
3
Repeat
Reclass Loop
Accountants reclass the same illegal pairs every period.
Root Operational Bottleneck
Valid department and cost-center combinations live in a setup guide and an error-correction sheet, so invalid pairs are caught only after the entry has posted.
Control Hazard & Audit Exposure
Expense is booked to combinations that do not exist in the segment table, and the correction sheet becomes the real chart of accounts.
Manifests in: ERP setup guide and accounting error correction spreadsheet
Deterministic Replacement (After)Golden Door Standard
Valid segment pairs are the system of record, versioned by effective date.

Entry Check
Each journal line is tested against the table in force on the posting date.

Author Fix
The poster corrects the pair before post; no weekly reclass file.
Deterministic Software Pattern
GL guardrail that validates every segment combination against the current cross-validation table at entry time and rejects the post when the pair is invalid.
Continuous Assertion Rule
Combination assertion: a journal line cannot post unless every segment pair is present on the active cross-validation table for that date.
