# Polynomial Operations (add/sub/mul/div/synthetic division) qualification

Verified clean in the current reconciled ledger.

Status: **VERIFIED_CLEAN**Lifecycle: **verified-clean**

## Ledger verdict

Verified clean in the current reconciled ledger.

**Status**: VERIFIED_CLEAN

**Tranche**: tranche-2

**Review vectors**: 4

**Ledger rows**: 1

## Applied errata

No tranche erratum is attached to this unique-name record.

## Adversarial re-test context

The full catalog was re-tested from boundary, convention, and self-check angles in 2,787 requests. Five genuine computational defects were independently verified and corrected. This page reports the current ledger state for this instrument; it does not imply product deployment or interface qualification.

## Release gate

Preserve the verified formulas and conventions, enforce boundary validation, and qualify the executable surface independently before release.
