+- NADDOD infrastructure classification pass on 2026-05-09:
+  - root cause:
+    - NADDOD remaining detail gaps were mostly not pluggable transceiver modules
+    - examples included switches, ConnectX adapter cards, Quantum/Spectrum infrastructure and OSFP cage systems
+  - DB correction:
+    - classified `18` NADDOD rows by source/title evidence:
+      - switch/Quantum/Spectrum/ONIE/ports => `Switch / Network Infrastructure`
+      - adapter/ConnectX => `NIC / Adapter`
+    - used allowed `data_confidence=scraped_unverified`
+    - added note: `classified as non-transceiver infrastructure product by source/title evidence`
+    - marked details verified only when a source product URL existed
+  - result:
+    - public health counters after pass:
+      - `details_verified=11466`
+      - `fully_verified=10177`
+      - total products `17647`
+    - TIP health stayed `healthy`
+    - load status `ok`
+    - memory used `12%`
+  - truth:
+    - these rows should not be treated as 1:1 optical transceiver equivalents
+    - they remain useful inventory/network infrastructure records, but need separate switch/NIC handling later
+
 - QSFPTEK cable/AOC parser hardening and DB detail backfill on 2026-05-09:
   - root cause:
     - QSFPTEK scraper parsed catalog rows but did not pass `productUrl` into `findOrCreateScrapedTransceiver`

+# NADDOD Infrastructure Classification
+
+Date: 2026-05-09
+Actor: Codex
+Scope: NADDOD remaining detail gaps
+Mode: DB-only classification
+
+## Root Cause
+
+Most remaining NADDOD detail gaps were not missing optical transceiver details. They were infrastructure products inside the transceiver table:
+
+- switches
+- ConnectX adapter cards
+- Quantum/Spectrum systems
+- ONIE/port/cage products
+
+## DB Correction
+
+Updated `18` rows by source/title evidence:
+
+- switch/Quantum/Spectrum/ONIE/ports => `Switch / Network Infrastructure`
+- adapter/ConnectX => `NIC / Adapter`
+
+Implementation notes:
+
+- used allowed `data_confidence=scraped_unverified`
+- added note: `classified as non-transceiver infrastructure product by source/title evidence`
+- marked `details_verified=true` only when a source product URL existed
+
+## Result
+
+Public TIP health after pass:
+
+- `details_verified=11466`
+- `fully_verified=10177`
+- total products: `17647`
+- status: `healthy`
+- load status: `ok`
+- memory used: `12%`
+
+## Training Note
+
+TIPLLM must not force switches/NICs/infrastructure into optical transceiver fields. These products can be source/detail verified as infrastructure records, but they must not participate in optical 1:1 equivalence matching.
