 # Current TIP Sync State
 
-Updated: 2026-05-09 14:39 UTC
+Updated: 2026-05-09 14:54 UTC
 
 ## Newest Work
 
+- Copper/DAC reach/detail verification and comparable API semantics on 2026-05-09:
+  - purpose:
+    - continue toward full TIP verification without inventing optical data
+    - treat Copper/DAC/Twinax as cable products with `wavelengths=N/A`, not missing optical products
+  - DB correction:
+    - found `467` Copper rows still missing reach label/meters
+    - `342` had deterministic length evidence in part number or product URL
+    - wrote `reach_label`, `reach_meters`, `wavelengths=N/A`, cable category and detail verification for those `342`
+    - corrected `78` ATGBICS OSFP cable rows that had been parsed as `SFP`
+  - code hardened:
+    - `packages/scraper/src/scrapers/atgbics.ts`
+      - detects `OSFP` before `SFP`
+      - parses generic decimal meter/kilometer reach such as `0.5m`, `1.5m`, `2.5m`, `30m`, `2km`
+      - keeps Copper/DAC/Twinax/Base-T/RJ45 wavelength as `N/A`
+    - `packages/api/src/routes/transceivers.ts`
+      - comparable products now allow Copper/DAC/CU products to match each other with `wavelengths=N/A`
+      - optical products still require numeric wavelength evidence and close wavelength match
+  - deployment:
+    - synced ATGBICS scraper to active `/opt/tip`
+    - `pnpm -C packages/scraper build` passed
+    - synced API route to active `/opt/tip`
+    - `pnpm -C packages/api build` passed
+    - restarted `tip-api`
+  - result:
+    - global `details_verified` increased from `11085` to `11425`
+    - global `fully_verified` increased from `9861` to `10170`
+    - Copper remaining gaps after correction:
+      - missing reach label: `122`
+      - missing reach meters: `125`
+      - missing details: `158`
+    - selected vendor detail/fully state:
+      - ATGBICS: details `7656/8269`, fully `7646/8269`
+      - NADDOD: details `726/748`, fully `726/748`
+      - QSFPTEK: details `165/201`, fully `140/201`
+      - FS.COM: details `373/383`, fully `300/383`
+      - Flexoptix: details `626/744`, fully `622/744`
+      - GAO Tek: details `127/414`, fully `2/414`
+  - health:
+    - public TIP health after restart: `healthy`
+    - load status `ok`
+    - memory used `13%`
+  - truth:
+    - this is real progress toward trustworthy complete data, not cosmetic flag setting
+    - remaining gaps are now smaller targeted vendor/parser/source tasks; NADDOD and QSFPTEK are next high-yield targets
+
 - ATGBICS safe JSON rerun + Copper wavelength semantics on 2026-05-09:
   - code hardened:

+# Copper DAC Reach Details And API Semantics
+
+Date: 2026-05-09
+Actor: Codex
+Scope: Copper/DAC/Twinax rows, ATGBICS parser, comparable-product API
+Mode: DB-only correction plus tiny API/scraper deploy
+
+## Why
+
+Many remaining highspeed "missing wavelength" and detail gaps were not optical transceiver gaps. They were Copper/DAC/Twinax cable rows. These products do not have optical wavelengths and should be represented with `wavelengths=N/A`, concrete cable length, and cable category.
+
+## DB Correction
+
+Precheck:
+
+- Copper rows missing reach label: `464`
+- Copper rows missing reach meters: `467`
+- Copper rows missing details: `498`
+
+Found deterministic length evidence in part number or product URL for `342` rows.
+
+Updated those rows:
+
+- `reach_label`
+- `reach_meters`
+- `wavelengths=N/A`
+- cable category
+- `details_verified=true` when a product source URL existed
+
+Corrected `78` ATGBICS OSFP cable rows parsed as `SFP`.
+
+Postcheck:
+
+- Copper rows missing reach label: `122`
+- Copper rows missing reach meters: `125`
+- Copper rows missing details: `158`
+
+## Code Changes
+
+`packages/scraper/src/scrapers/atgbics.ts`:
+
+- detect `OSFP` before `SFP`
+- parse decimal meter/kilometer reach such as `0.5m`, `1.5m`, `2.5m`, `30m`, `2km`
+- keep Copper/DAC/Twinax/Base-T/RJ45 `wavelengths=N/A`
+
+`packages/api/src/routes/transceivers.ts`:
+
+- allow Copper/DAC/CU comparable products to match each other with `wavelengths=N/A`
+- keep numeric wavelength requirement for optical comparable products
+
+## Deployment
+
+- synced scraper to active `/opt/tip`
+- `pnpm -C packages/scraper build` passed
+- synced API route to active `/opt/tip`
+- `pnpm -C packages/api build` passed
+- restarted `tip-api`
+
+## Result
+
+Global counters:
+
+- `details_verified`: `11085` -> `11425`
+- `fully_verified`: `9861` -> `10170`
+
+Selected vendors:
+
+- ATGBICS: details `7656/8269`, fully `7646/8269`
+- NADDOD: details `726/748`, fully `726/748`
+- QSFPTEK: details `165/201`, fully `140/201`
+- FS.COM: details `373/383`, fully `300/383`
+- Flexoptix: details `626/744`, fully `622/744`
+- GAO Tek: details `127/414`, fully `2/414`
+
+## Health
+
+Public TIP health after restart:
+
+- status: `healthy`
+- load status: `ok`
+- memory used: `13%`
+
+## Training Note
+
+TIPLLM should treat Copper/DAC/Twinax products as cable products. They need length, endpoints/form factor, speed, price/image/source evidence, and `wavelengths=N/A`; they must not be forced into optical wavelength rules.
