IndexTwo systems · four instruments · two emerging programs
Working systems, built so they can be measured.
Geiger Capital builds small production systems, runs them in the open, and publishes the evidence needed to understand how they behave.
Index of work
SystemsRunning, with public state
- 01 Parallel Works Operating system A swappable operating layer for isolated Minecraft worlds, with public status, verified backups and security controls enforced against real play.
- 02 Fin Platform Holdings Research platform A synthetic financial institution for payments, screening, treasury and reconciliation, with separated roles, four-eyes controls and tested recovery.
InstrumentsRun against systems, evidenced by artifact
- 03 Chainwatch Security instrument A supply-chain diff analyser that compares releases and scores six risk dimensions against live threat feeds.
- 04 Agentlens Governance instrument An inventory that finds AI agents and derives which remain unmonitored from egress, credential and deployment evidence.
- 05 Lattice Lab Research instrument A closed harness measuring how much of a 48-bit java.util.Random seed must leak before the rest can be rebuilt.
- 06 RepoAuditor Review instrument A challenge-driven security review pipeline that turns scanner and model candidates into a reviewed engineering backlog.
Emerging workPrivate, with bounded public claims
- 07 Blackwall Experimental control plane The separately approved enforcement plane paired with Agentlens, with bounded VPS and disposable-cloud mechanisms verified.
- 08 ExposureLab Private research · working name A work-in-progress research program. This listing records only that the work exists; no technical, validation or release claim is made.
Studio
Two systems, four instruments and two emerging programs, one method: stand the thing up for real, then instrument it until its behaviour is legible.
A control that has never been enforced against live traffic is a claim, not a control. Both systems here exist to close that gap. One puts a documented SDLC around infrastructure that real players depend on. The other gives autonomous agents a genuine organisation to discover, so governance questions can be asked of something with a real surface instead of a diagram.
The instruments are the same argument in reverse. A supply-chain analyser and an agent inventory are only worth something once they have been run against a system that can push back, which is what the two above are for.
Everything is small on purpose. One operator, published runbooks, and enough uptime that the numbers mean something.
