The Server Split That Almost Didn't Happen

The first import was the first failure: ‘ERR_MODULE_NOT_FOUND’. The code wouldn’t even boot. But back up. Three months ago I wrote about the monorepo split. API server, dashboard, CLI — three work...

Your PID File Is a Lie: What Cloudflare Tunnel Taught Me About Process Supervision

Two ways to start the same server. One worked. The other gave me Bad Gateway. They ran the same code, listened on the same port, used the same config. The difference was invisible. Context I am ...

I Opened My First Open Source PRs. None of Them Are Merged Yet.

I’ve been writing software professionally for years, but somehow I had never really contributed to an open-source project. I’ve used plenty of them. Forked them. Patched them. Built things on top ...

Headroom, Round Two: Four Walls Between Me and a Working Token Saver

The 403 That Wasn't: How Warp, 9router, and Cloudflare Masked Two Separate Failures

My Warp agent stopped talking to 9router. Quick background: 9router is my AI routing layer — a Hono server that proxies LLM requests through fallback providers. It runs locally via a Cloudflare tu...

Building Memory Into 9router: A Proxy-Layer Experiment

Every coding AI I tried was great at problems, terrible at context. I’d start a new session and describe my stack, my preferences, my ongoing projects — everything the AI needed to be useful. Next...

This Is My ADE

I hit send on a prompt. Watched the spinner. Started calculating — was I past the cap yet? Three weeks into the billing cycle, OpenCode Go had hit its limit. I’d been conditioned to expect the erro...
