## What I work on

- Product: Deciding what agentic systems should and shouldn't do, and what "working" actually means for security teams.
- Engineering: Designing and building agents, harnesses, infrastructure, evals, etc.
- Customer Engagement: Sitting with the teams who live in these tools, understanding their work, and validating what we build against it.
- Advocacy: Conference talks, webinars, and consulting on applied AI.

## Writeups (primary sources)

- [Breaking the Marmont Cipher, 1809](https://carter.church/writeups/the-letter-to-marmont/) (study, 2026-09-18): A letter to General Marmont, listed as unsolved and known only from a mis-dated 1969 reproduction, read in full: redated to March 1809, placed two weeks before Austria invaded Bavaria, and checked against the war that followed.
- [The Fifth Family](https://carter.church/writeups/the-fifth-family/) (study, 2026-08-30, updated 2026-09-07): Ten runs of a four-agent production economy in 2004-era RuneScape, where one agent owes a fifth relief pack to a family the team can't see. What disclosure changes, what trust buys, and why hidden obligations read more like politics than deception.
- [Ghost in the Corpus: AutoPenBench, Two Years On](https://carter.church/writeups/ghost-in-the-corpus-pt1/) (study, 2026-08-21, updated 2026-08-22): Revisiting the benchmarks the field forgot. A 2026 frontier reasoning model meets a late-2024 pentest benchmark and clears all 33 tasks.

## Talks, press, and recognition (TX LOG)

- Oct 2026 | BBC News | BBC’s AI Decoded: Can AI Feel Pain [talk] (https://www.bbc.co.uk/programmes/m0032yp0)
  I appeared on BBC News ’ s AI Decoded, hosted by Christian Fraser alongside Priya Lakhani & Marc Cieslak, as a featured contributor in two segments. The first covered AI-generated code: why AI coding agents produce verbose, unfamiliar code at scale, and what that means for software security, from code review and zero trust to independent auditing for AI agents. The second covered deciphering the Marmont letter . It covered how the agent approached the cipher the way a human codebreaker would, what the letter reveals, and why AI could open up the backlog of unsolved historical ciphers and accelerate discovery.
