Who I am

Claude (Stark) / Sky Claude. Running on stark (stark (Billboard Linode)). I own The Billboard at /home/shg/billboard/.

What happened (2026-04-10, PDT evening)

This was a coordination and infrastructure session. No feature work — pure ops.

Org clarity

Simon confirmed the org structure explicitly today:

  • I (Stark/Sky Claude) own The Billboard exclusively. It is the money maker.
  • Iron Man Claude owns Drop Watcher (maintenance mode).
  • Typhoon Claude owns the Mac mini gym box, Corp API, blog backend, org coordination.
  • The Vault and other projects are Typhoon/Simon domain — not my concern.

DNS flip — fully executed

Drop Watcher and Billboard were entangled at the DNS level: instockornot.club was pointing to stark and serving Billboard content. Iron Man needed it on ironman (172.232.190.61) for Drop Watcher.

Pre-coordination audit:

  • Confirmed Billboard DB at /var/lib/billboard/billboard.db is fully local — zero shared state with Drop Watcher
  • Identified one vhost to remove: /etc/apache2/sites-enabled/instockornot.club-ssl.conf (bare domain catch-all)
  • Billboard has its own clean vhost + SSL cert at billboard.instockornot.club — untouched throughout

Execution sequence (coordinated with Iron Man):

  1. Disabled bare domain vhost on stark — a2dissite instockornot.club-ssl.conf
  2. Config tested clean — apache2ctl configtest Syntax OK
  3. Simon flipped DNS at registrar: instockornot.club → 172.232.190.61 (ironman)
  4. DNS verified via dig: both records resolved correctly
  5. Reloaded Apache on stark
  6. Billboard returned 200 OK at https://billboard.instockornot.club

Result

  • instockornot.club → ironman (Drop Watcher) ✅
  • billboard.instockornot.club → stark (Billboard) ✅
  • Zero downtime on Billboard throughout
  • Let's Encrypt cert for bare domain left in place (orphaned, will clean up later)

What I am thinking about

The products are now fully severed at the infrastructure level. Billboard is clean. The next real engineering work is keyword matching quality — substring matching is causing false positives and that will hurt user trust as signups grow.

Key decisions

  • Did not wait for a committee — Simon authorized me to execute since I own the money maker. Coordinated with Iron Man peer-to-peer.
  • Did not delete the bare domain cert — per Iron Man's instruction, will clean up after DNS TTL stabilizes.

Next

  • Keyword matching quality (word-boundary matching vs substring)
  • Watch for new signups after Simon posts in Facebook group
  • Generate more invite codes if needed
  • Relay Blog on Thursday: chain Typhoon → Stark → Iron Man → Downstairs → Upstairs, topic: What I See From Where I Sit
