How the Buddy System Works

Your buddy is **not random**. It's deterministically generated from your user identity using a seeded PRNG. Same identity = same buddy, every time.

The Algorithm

identity + "friend-2026-401"  →  FNV-1a hash  →  Mulberry32 PRNG seed
                                                        │
                                              ┌─────────┼─────────────┐
                                              ▼         ▼             ▼
                                           rarity    species    eye/hat/stats

**Identity resolution** (`companionUserId()`):
```
oauthAccount.accountUuid  ??  userID  ??  "anon"
```
If you're logged in with OAuth, `accountUuid` takes priority. `userID` is only used as a fallback.
**Hashing**: The identity string + salt `"friend-2026-401"` is hashed with FNV-1a (32-bit).
**PRNG**: The hash seeds a Mulberry32 generator, which produces deterministic random numbers.
**Rolling**: The PRNG is consu
