+# ATGBICS Deterministic Special-Case Backfill - 2026-05-09
+
+## Precheck
+
+- After the explicit URL evidence pass, ATGBICS still had `139` near-complete rows
+- `32` matched safe protocol/product-class cases:
+  - loopback/test modules
+  - 10GBASE-T / RJ45 copper
+  - 10GBASE-LRM
+  - BX60 / BXD-60 / BXU-60
+  - CWDM 10G 60km
+  - CSR rows
+
+## DB Correction
+
+- Loopback/test modules -> `N/A` reach/fiber/wavelength, `Loopback / Test Module`
+- 10GBASE-T/RJ45 -> `30m`, `Copper`, `N/A`
+- LRM -> `220m`, `MMF`, `1310`
+- BX60 -> `60km`, `SMF`, directional BiDi wavelength evidence
+- CWDM 10G 60 -> `60km`, `SMF`, source wavelength
+- CSR -> `400m`, `MMF`, `850`
+
+## Result
+
+- `32` ATGBICS rows detail-verified
+- `32` additional rows promoted to fully verified
+- ATGBICS near-complete missing details reduced from `139` to `107`
+- Global `details_verified=12030`
+- Global `fully_verified=10753`
+
+## Health
+
+- TIP public health stayed `healthy`
+- Load status stayed `ok`
+- Memory used `12%`
+
+## Truth Policy
+
+Remaining ATGBICS rows need detail-page extraction. They are mostly generic OEM/part-number pages where the URL slug does not encode the reach.
