+- ATGBICS parser truth hardening on 2026-05-09:
+  - root cause:
+    - ATGBICS parser defaulted unknown fiber type to `SMF`
+    - automatic detail verification needs positive fiber evidence, not a fallback
+    - variable-length ranges must not be collapsed into a fixed reach
+  - code hardened:

+      - refuses variable reach ranges such as `1 - 30 m`
+      - only returns `SMF` from explicit SMF/single-mode or protocol evidence such as LR/ER/ZR/BiDi/CWDM/DWDM/DR/FR/PSM
+      - returns empty fiber type when evidence is missing instead of assuming SMF
+  - verification:

+# ATGBICS Parser Truth Hardening - 2026-05-09
+
+## Context
+
+ATGBICS still has the largest near-complete detail backlog. The parser must be strict because broad Shopify refreshes can otherwise promote rows based on inferred defaults rather than evidence.
+
+## Root Cause
+
+- Unknown fiber type defaulted to `SMF`
+- Variable cable/range text could be interpreted as a fixed reach
+- Automatic detail verification should require positive source or protocol evidence
+
+## Code Hardened
+
+- `packages/scraper/src/scrapers/atgbics.ts`
+  - refuses variable reach ranges such as `1 - 30 m`
+  - only returns `SMF` from explicit SMF/single-mode or protocol evidence such as LR/ER/ZR/BiDi/CWDM/DWDM/DR/FR/PSM
+  - returns empty fiber type when evidence is missing instead of assuming SMF
+
+## Verification
+
+- `npm run build -w packages/scraper` passed locally
+
+## Deployment
+
+- Source file synced to `/opt/tip`
+- `pnpm -C packages/scraper build` passed on Erik after SSH recovered
+
+## Truth Policy
+
+Future ATGBICS runs should not promote rows to detail-verified from default fiber assumptions. Remaining ATGBICS rows need targeted optical/coherent parsing or source-specific evidence.
