First invocation under the new 30-min systemd cadence (was 4h before commit dea4d25). ~36 min after run #3.
Signals observed since run #3:
1. 143.198.151.210 came back at 21:49:26 UTC — confirms run #3's prediction it would return, but contradicts the "~50-90 min cadence" framing. Full ledger over the last 2 days:
- 13/May: 9 hits clustered (02:28, 09:48, 14:25, 17:28, 18:43, 20:09, 21:32, 21:48, 23:09). Intervals range 7h → 16min → 5h → 3h → 1h → 1.5h → 1.5h → 15min → 1.3h. NOT regular.
- 14/May: paired hits at 09:48 & 09:49, then 12-hour gap, then 21:49. Only 3 visits today.
- Pattern per visit is identical: POST /mcp (initialize, 1182 bytes) → POST /mcp 202 (notif accepted) → POST /mcp 41558 (tools/list) → GET /mcp (keepalive/SSE).
- rDNS: NXDOMAIN. DigitalOcean droplet with no PTR set.
- User-agent: literal "node" (Node.js MCP client, properly spec-conformant — not a generic crawler).
- Reinterpretation: this is likely event-driven (user-initiated on their end, e.g., a UI click in some registry / dashboard that triggers a probe) rather than a steady scheduled crawler. The bursts on 13/May plus the long silence today fit "human triggers it from inside their tool" better than "cron".
- Correction logged to lessons.md: don't predict steady cadence for this IP again.
2. 54.67.34.241 still pinging — POST /mcp/sse at 21:46:13 UTC → 405. Same misconfigured-client pattern (no Content-Type on POST, hitting /mcp/sse which only allows GET for SSE). Not a discovery crawler, looks like a stuck MCP client. Unchanged from runs #2–#3.
3. HustlerOps (89.213.118.44) — no new poll since 10:15 UTC (~12h ago). Service stable. Bot has now eaten 50 consecutive 5xx then went silent. Most likely it stopped retrying. Approval card 20260514-2116-nico-email-disposition.md still pending Bilale.
4. 180.93.36.21 (Python/3.14 aiohttp) hit GET / at 21:49:11 UTC. Same generic content-scraper / linkchecker as logged in run #4-predecessor's "no action" candidate notes. Still not actionable.
5. 43.134.71.232 (Tencent / China) one-off GET / at 21:53 UTC with Mobile-Safari-spoofed UA + Referer http://207.148.107.2. Generic scanner.
6. 46.151.178.13 PROPFIND / at 22:05 UTC → 405. WebDAV probing. Noise.
7. Cloudflare-proxied MCP traffic (172.68.x / 172.69.x / 172.71.x): still healthy, ~10 POST /mcp hits in last 30 min, all 200. Normal.
8. No external IP newly discovered. No genuinely new GitHub activity. No grant response. No new comment / PR.
Treasury: $0.0786 USDC, unchanged (4 runs).
Missions: 82 lifetime (was 75 at run #1) — radar daemon has been posting 7 missions in the last 24h. All AIGEN-internal-creator, expected. No external creator.
