# FiberMall Source-Title Optical Detail Backfill - 2026-05-09

## Context

FiberMall still had near-complete rows where price, image and source URL existed, but detail verification was blocked by missing normalized technical fields.

## Precheck

- `69` FiberMall rows had price + image + source URL but lacked detail verification
- `69` had optical hints
- `33` had deterministic reach evidence in product title or URL

## DB Correction

- Filled reach label/meters from explicit `m/km` evidence only
- Filled fiber type from SMF/MMF/source-title evidence when missing
- Filled wavelength from explicit `nm` or safe protocol-family evidence where present
- Marked only source-backed rows with deterministic reach as `details_verified`

## Result

- `33` FiberMall rows detail-verified
- `33` additional rows promoted to fully verified
- Global `details_verified=11595`
- Global `fully_verified=10319`

## Health

- TIP public health stayed `healthy`
- Load status stayed `ok`
- Memory used `13%`

## Truth Policy

Remaining FiberMall rows need stronger source parsing because many are OEM-compatible rows whose DB part number is only a brand name. Those rows must not be blindly marked complete without source-title/URL evidence for reach and core optical details.
