 ## Newest Work
 
+- ATGBICS Cable/AOC detail backfill on 2026-05-09:
+  - current ATGBICS near-complete state before pass:
+    - `581` rows had price + image + product source URL but still lacked detail verification
+    - `0` of those were core-complete optical rows
+    - `101` had clear Cable/AOC/Copper/Twinax/Breakout hints
+    - `22` had coherent/ZR/DCO/C-band hints and were left for a later source-specific coherent parser
+  - DB correction:
+    - used deterministic length evidence from product URL / part text
+    - updated `96` ATGBICS Cable/AOC rows with:
+      - reach label/meters
+      - cable/AOC/Copper classification
+      - `wavelengths=N/A` for Copper/DAC/Twinax
+      - source-backed `details_verified`
+    - promoted `109` rows to `fully_verified`
+  - global result after pass:
+    - `details_verified=11562`
+    - `fully_verified=10286`
+    - total products `17647`
+  - health:
+    - public TIP health: `healthy`
+    - load status `ok`
+    - memory used `13%`
+  - truth:
+    - repeated broad ATGBICS JSON runs are low-yield now
+    - remaining ATGBICS gaps need targeted optical/coherent parsing, especially ZR/DCO/C-band/LAN-WDM and non-cable products missing reach/fiber
+
 - NADDOD infrastructure classification pass on 2026-05-09:
   - root cause:
     - NADDOD remaining detail gaps were mostly not pluggable transceiver modules

+# ATGBICS Cable AOC Detail Backfill
+
+Date: 2026-05-09
+Actor: Codex
+Scope: ATGBICS near-complete rows
+Mode: DB-only deterministic cable/AOC backfill
+
+## Precheck
+
+ATGBICS near-complete rows before pass:
+
+- price + image + product source URL but no details: `581`
+- core-complete optical rows among them: `0`
+- Cable/AOC/Copper/Twinax/Breakout hints: `101`
+- coherent/ZR/DCO/C-band hints: `22`
+
+The coherent/ZR/DCO rows were intentionally left for a later source-specific parser.
+
+## DB Correction
+
+Used deterministic length evidence from product URL / part text.
+
+Updated `96` ATGBICS Cable/AOC rows:
+
+- reach label/meters
+- cable/AOC/Copper classification
+- `wavelengths=N/A` for Copper/DAC/Twinax
+- source-backed `details_verified`
+
+Promoted `109` rows to `fully_verified`.
+
+## Result
+
+Global counters after pass:
+
+- total products: `17647`
+- `details_verified=11562`
+- `fully_verified=10286`
+
+Public TIP health:
+
+- status: `healthy`
+- load status: `ok`
+- memory used: `13%`
+
+## Training Note
+
+TIPLLM should stop repeating broad ATGBICS Shopify JSON runs for this class of gaps. Remaining ATGBICS work needs targeted optical/coherent parsing, especially ZR/DCO/C-band/LAN-WDM, plus non-cable products missing reach/fiber.
