 ## Newest Work
 
+- DB-only highspeed wavelength evidence backfill on 2026-05-09:
+  - purpose:
+    - improve product-level technical completeness and future 1:1 comparison quality without running a browser crawler on Erik
+  - method:
+    - only used existing DB evidence from part numbers, standard names, notes and product URLs
+    - only filled wavelengths when evidence was deterministic:
+      - explicit `850nm`, `1310nm`, `1311nm`, or `1550nm`
+      - MMF plus SR/SR4/SR8/SRBD/VR/ESR/CSR family => `850`
+      - SMF plus DR/FR/LR/ER/PSM family => `1310`
+      - SMF plus CWDM4 => `1271,1291,1311,1331`
+    - skipped ambiguous highspeed rows instead of inventing data
+  - updated rows:
+    - `129` rows set to `1310`
+    - `40` rows set to `850`
+    - `18` rows set to `1271,1291,1311,1331`
+    - total updated: `187`
+  - highspeed wavelength gap after update:
+    - highspeed rows: `4438`
+    - still missing wavelengths: `1908`
+    - largest remaining gaps:
+      - ATGBICS `663`
+      - NADDOD `419`
+      - Flexoptix `183`
+      - Eoptolink `141`
+      - FS.COM `114`
+      - QSFPTEK `97`
+  - health:
+    - public TIP health after update: `healthy`
+    - load status `ok`
+    - memory used `13%`
+  - truth:
+    - this was an evidence backfill, not a claim of full source verification
+    - remaining wavelength gaps need vendor-specific parsers/crawlers or stronger source text
+
 - Strict active equivalence sweep + reach-meter backfill on 2026-05-09:
   - follow-up after the FS.com `QDD-2FR4-800G` false-comparable correction
   - audited all active `approved/auto_approved` equivalence matches for hard 1:1 risks:

+# Highspeed Wavelength DB Backfill
+
+Date: 2026-05-09
+Actor: Codex
+Scope: TIP highspeed transceivers missing `wavelengths`
+Mode: DB-only, evidence constrained, Erik-safe
+
+## Why
+
+After tightening comparable-product logic, missing wavelength evidence became one of the biggest remaining blockers for reliable 1:1 competitor matching. A browser crawl was not needed for rows where the existing DB already contained deterministic optical evidence in part numbers, standard names, notes, or product URLs.
+
+## Rule
+
+Only fill `wavelengths` when the DB text gives deterministic evidence:
+
+- explicit `850nm`, `1310nm`, `1311nm`, or `1550nm`
+- MMF plus SR/SR4/SR8/SRBD/VR/ESR/CSR family => `850`
+- SMF plus DR/FR/LR/ER/PSM family => `1310`
+- SMF plus CWDM4 => `1271,1291,1311,1331`
+
+Ambiguous rows were skipped.
+
+## Result
+
+Rows updated:
+
+- `129` rows set to `1310`
+- `40` rows set to `850`
+- `18` rows set to `1271,1291,1311,1331`
+- total: `187`
+
+Post-update highspeed wavelength gap:
+
+- highspeed rows: `4438`
+- still missing wavelengths: `1908`
+
+Largest remaining missing-wavelength vendors:
+
+- ATGBICS: `663`
+- NADDOD: `419`
+- Flexoptix: `183`
+- Eoptolink: `141`
+- FS.COM: `114`
+- QSFPTEK: `97`
+
+## Health
+
+Public TIP health after the update:
+
+- status: `healthy`
+- load status: `ok`
+- memory used: `13%`
+
+## Training Note
+
+TIPLLM should separate deterministic evidence backfill from source verification. It is safe to infer wavelengths from established optical family codes only when the fiber class matches; otherwise the row must remain unresolved until a vendor-specific parser or source crawl supplies stronger evidence.
