Summary

Update docs/user-stories.md from v1.3 to v1.4 per the host rant 2026-08-14T21:32:47 (修正新人赠送机制 — 改为每日送 1 点（有效期 1 天）、连送 10 天，防薅羊毛).

The old "register → 10 gift points valid 1 week" is replaced by a daily gift program (anti-abuse):

1. 1 point per day（每日 1 点）— not a one-time 10 points at registration;
2. Each day's point is valid for 1 day（当日有效，过期清零）;
3. Granted for 10 consecutive natural days from registration（注册起连续 10 个自然日，每天 1 点，10 天后停止）;
4. The user must log in / come back each day to claim that day's point — a missed day's point is not issued / not accumulated（不积累、不补发）;
5. Unchanged: sharing earnings permanent · future top-up permanent · consumption deducts expiring (gift) points first · public edition has no top-up channel yet.

Changes:

• Core mechanism table: Gift points（赠送点数） definition → daily 1 pt / 1-day validity / 10 consecutive days + anti-abuse motivation
• Public edition scene description & points-model note (v1.2 → v1.4)
• US-3 (registration AC), US-22 (new-user gift), US-23 (source & validity example), US-4 (placeholder note)
• Key flow J-1 (mermaid + steps)
• Edge case E-13 → daily gift expiry; new E-14 (daily gift not claimed)
• Alignment table → v1.4
