# Phase 10.9.2.2 — Revenue QA Version Compatibility Hotfix

## Evidence-driven root cause

The 10.9.2.1 Evidence proved that the real browser rendering gate passed 5/5 and that all ten revenue parity rows passed with zero differences. The final result was incorrectly marked FAIL because the older Phase 10.9.1 parity QA page required the installed release to equal `10.9.1` exactly. Once the site advanced to `10.9.2.1`, that historical QA gate failed even though all revenue results passed.

## Fix

- Revenue parity QA now accepts installed releases greater than or equal to `10.9.1`.
- Revenue chart QA now accepts installed releases greater than or equal to `10.9.2`.
- No Revenue SQL, Oracle logic, parity calculation, chart runtime, executive UI, or permission logic is changed.
- Oracle write operations remain NONE.

## Acceptance

- Revenue parity: 10/10 PASS, failures 0.
- Browser rendering: 5/5 PASS, failures 0.
- Chart structural QA: PASS.
- Final Full QA: PASS.
