# F1.2 Devil's Advocate Review: Post-Fix Verification

## Verdict: PASS

After fixes applied, re-checking the 4 original issues:

### 1. Star-link topology → ✅ Fixed
- Before: 4/6 cards linked to `ai-value-chain-smile-curve`
- After: Cards now form a mesh — excel→saas-network, excel→document-as-app, excel→ltf, figma→saas-network, figma→tool-to-intelligence, tool-to-intelligence→figma, tool-to-intelligence→document-as-app, ltf→document-as-app, saas-network→excel, saas-network→figma
- `ai-value-chain-smile-curve` removed as lazy catch-all link

### 2. saas-network-effect conceptual link → ✅ Fixed
- Removed incorrect "定价策略异曲同工" claim about mitsein-investment-thesis
- Replaced with valid comparison to figma-product-distribution-fit (two types of network effects)

### 3. tool-to-intelligence atomicity → ✅ Fixed
- Removed 飞书 tangent
- Added "(约 2021-2022 年)" time context for staleness awareness
- Now purely about the 4-step model with Teams education as the case

### 4. ltf insight density → ✅ Fixed
- Rewritten from "LTF 是什么" to "LTF 为什么是引力中心"
- Added failure mode analysis (LTF fails when relationships > categories)
- Added memex as counter-example (network > tree)

## Remaining Minor Concerns
- 🔵 None blocking. All 6 cards now have `source: flomo`, proper mesh links, and atomic insights.

## Overall: 🔵 PASS — All yellow issues resolved.
