# F5.2 Devil's Advocate Review — MSFT+伺候领导+职能

## Challenge 1: Is 96% skip rate too aggressive?

Reviewed all 24 skipped memos:
- 伺候领导 (5): Pure MSFT org politics — team dynamics, promotion anxiety, review prep. Zero transferable value. ✅ Skip justified.
- MSFT contacts/links/numbers (8): Literal internal links, phone extensions, DAU numbers. ✅ Skip justified.
- TikTok research (1): "Short video enables discovery" — well-known by now, not an insight. ✅ Skip justified.
- Page loading (1): Blog post introduction, not an insight. ✅ Skip justified.
- FY23 Planning (1): Internal planning fragments with no context. ✅ Skip justified.
- PDSA (1): Role definition — has some value ("从客户学习→归纳场景→反馈产品") but too role-specific to be atomic Zettelkasten insight. Borderline. 🟡 Could argue for keeping, but the insight density is low.
- PM split (1): 69 chars, states the obvious. ✅ Skip justified.

**Conclusion**: Skip rate justified. No hidden gems buried.

## Challenge 2: Is "product weight determines CS" just "enterprise vs SMB" restated?

The framing IS more specific than generic enterprise/SMB split. The card names the mechanism: it's not company size that matters, it's **product heaviness** (tool vs management software). A lightweight product sold to enterprises still gets online CS. A heavy product sold to SMBs still needs consulting. This is a genuinely useful reframe.

🔵 Not just common knowledge dressed up.

## Challenge 3: Are the wikilinks forced?

- `[[figma-product-distribution-fit]]` — PLG as CS substitute for light products. Genuine connection.
- `[[saas-network-effect-cross-enterprise]]` — Carta's 409A as CS depth for heavy products. Genuine connection.

🔵 Both links explain WHY they're related, not just "see also."

## Challenge 4: Missing time anchor?

The CS model framework is timeless/structural, not time-dependent. No time anchor needed.

🔵 Fine.

## Challenge 5: Single card for 25 memos — is 1 enough?

With 14 MSFT-specific memos, 5 org-politics memos, and 6 miscellaneous fragments, yes. The only other candidate was the TikTok "discovery" memo, but that's been said better elsewhere. 1 card is honest.

**Verdict: PASS**
