Strict Active Equivalence Sweep

Date: 2026-05-09 Actor: Codex Scope: TIP active equivalence matches, DB-only evidence, Erik-safe

Why

After the operator caught the false comparable product for FS.com QDD-2FR4-800G, Codex ran a broader DB-only safety sweep over active approved and auto_approved equivalence matches. The goal was to catch any remaining active 1:1 mistakes before they show up as trusted competitor products in the dashboard.

Checks

Hard active-match risks checked:

• breakout/AOC/DAC/cable class mismatch
• reach mismatch when both sides have known reach
• fiber mismatch when both sides have known fiber
• primary wavelength mismatch when both sides have known wavelength
• missing core evidence on active matches

Result

Rejected 16 active false positives:

• Flexoptix 400G/100G pluggable optics matched to ATGBICS AOC/breakout products
• Flexoptix Q.851HG.03 300m MMF matched to NADDOD 70m and 40km rows
• Flexoptix Q.854HG.01.P 100m MMF matched to a NADDOD 1m row

Backfilled numeric reach evidence:

• 269 rows with km reach labels received reach_meters
• 131 rows with m reach labels received reach_meters
• remaining reach labels without meters are only N/A accessory/control rows

Post-sweep active risk counts:

• active approved/auto-approved matches: 34051
• breakout-class mismatches: 0
• reach mismatches: 0
• fiber mismatches: 0
• wavelength mismatches: 0
• missing core evidence: 0

Live counters after the sweep:

• equivalences: pending=0, approved=1987, auto_approved=32064, rejected=148382, due_research=0
• product verification: total 17647, price 11557, image 11963, details 11085, fully 9861

Training Note

TIPLLM should treat unknown reach/fiber/wavelength as insufficient evidence for final 1:1 competitor approval, not as a wildcard. Breakout/AOC/DAC/cable class must be part of the equivalence key.
