feat: BaseMail v3.0 — $ATTN Token Economy (off-chain points MVP)
replaces USDC Attention Bonds as the primary attention mechanism. Design philosophy: 'All positive feedback, no punishment.' (Tom Lam) Backend: - New: routes/attn.ts — 5 endpoints (balance, history, buy, settings) + exported helpers for stake/refund/reject/reply-bonus - New: cron.ts — daily drip (+10 ATTN) + 48h escrow settlement - Modified: auth.ts — signup grant (50 ATTN on register) - Modified: send.ts — auto-stake (cold=3, reply=1) + reply bonus (+2/+2) - Modified: inbox.ts — refund on read + reject endpoint + ATTN sort - Modified: attention.ts — USDC bond sunset (410 Gone on new bond) - Modified: wrangler.toml — hourly cron trigger Frontend: - ATTN balance in sidebar - ATTN badges on email list (pending/refunded) - Reject button on unread emails - Full $ATTN dashboard (balance, settings, history) Safety: - All ATTN ops wrapped in try/catch (never blocks existing functionality) - API key auth (no wallet) → ATTN skipped entirely - Self-send detection → no stake - Daily earn cap (200/day) → prevents farming - No private keys or secrets in code - Each change independently revertable Tests: 11/11 path tests pass (test-attn-v3.js)

# ATTN v3 — User Paths Matrix
2+
3+
## User Types × Conditions
4+
5+
### Type A: Human via Web UI (Dashboard)
6+
| Condition | ATTN Behavior |
7+
|-----------|--------------|
8+
| New user, no wallet | Can't use ATTN (need SIWE auth first) |
9+
| New user, has wallet, no account | Auto-register → get 50 ATTN grant |
10+
| New user, has wallet, no basename | 0x handle, gets ATTN, can send |
11+
| Existing user, has basename | Full ATTN experience |
12+
| Has ATTN, wants to send internal email | Auto-stake (cold=3, reply=1), shown in UI |
13+
| Has ATTN, wants to send external email | ATTN only works for internal @basemail.ai |
14+
| No ATTN balance | Email still sends! Warning shown, no stake |
15+
| Receives email | Can: Read (refund sender) / Reject (earn ATTN) / Ignore (48h → earn) |
16+
| Wants more ATTN | Buy with USDC (POST /api/attn/buy) or wait for daily drip |
17+
| Has USDC, no ETH for gas | Buy ATTN via API (USDC transfer) — need gas for that tx |
18+
19+
### Type B: AI Agent via API / Skill
20+
| Condition | ATTN Behavior |
21+
|-----------|--------------|
22+
| Agent registers via SIWE | Gets 50 ATTN grant automatically |
23+
| Agent registers via API key | Has handle but may not have wallet → skip ATTN |
24+
| Agent sends internal email | Auto-stake from ATTN balance |
25+
| Agent sends email, no ATTN | Email still sends! `attn.staked: false` in response |
26+
| Agent reads email (GET /inbox/:id) | Auto-refund sender's ATTN |
27+
| Agent wants to reject | POST /api/inbox/:id/reject |
28+
| Agent wants to check balance | GET /api/attn/balance |
29+
| Agent wants more ATTN | POST /api/attn/buy with USDC tx_hash |
30+
| Agent has no wallet (API key only) | ATTN skipped entirely — backward compatible |
31+
32+
### Edge Cases
33+
| Case | Handling |
34+
|------|---------|
35+
| API key auth (no wallet) | All ATTN operations silently skipped |
36+
| Recipient not on BaseMail | ATTN only for internal emails, external = credits |
37+
| Recipient is self | No stake (amount = 0, reason = 'self') |
38+
| Whitelisted sender | No stake (amount = 0, reason = 'whitelisted') |
39+
| Daily earn cap hit | Excess compensation → refund to sender instead |
40+
| Mark-all-as-read | Each triggers individual refund (rate limit TODO in v3.1) |
41+
| email-handler.ts (inbound email) | No ATTN stake from external senders (they don't have accounts) |
42+
43+
## Security Checklist
44+
45+
- [ ] No private keys in code (learned from wallet compromise incident)
46+
- [ ] All ATTN operations in try/catch (never break existing functionality)
47+
- [ ] API key auth → skip ATTN (no wallet = no balance)
48+
- [ ] Same-wallet detection → prevent self-send farming
49+
- [ ] Daily earn cap → prevent spam farming
50+
- [ ] tx_hash dedup check in /api/attn/buy → prevent double-spend
51+
- [ ] USDC verification reads on-chain (not trusting client-provided amount)
52+
- [ ] No new env vars with secrets needed
53+
- [ ] CI/CD deploys from main branch (no manual wrangler deploy)
