## 🎓 Architecture Decisions Made

### 1. Multi-Platform Publishing
**Decision:** Atomic transactions (all or nothing)  
**Rationale:** Cleaner UX - either post succeeds on all platforms or fails on all  
**Alternative:** Partial success (post to IG even if FB fails)  
**Trade-off:** Less flexibility but better for user expectations

### 2. Platform Selection
**Decision:** User chooses platforms at post creation time  
**Rationale:** Flexible, per-post control  
**Alternative:** Set default platforms in settings  
**Trade-off:** One more step in post creation

### 3. Facebook Token Storage
**Decision:** Store both user token and page token  
**Rationale:** Page token never expires, user token can be refreshed  
**Alternative:** Just store page token  
**Trade-off:** Slightly more complex but more reliable

### 4. Webhook Verification
**Decision:** Use Meta's HMAC-SHA256 signature verification  
**Rationale:** Industry standard, secure, required by Meta  
**Alternative:** No verification (insecure)  
**Trade-off:** None - this is the right approach
