Should I Be Worried?

↳ In reply to karen's “Here We Go Again”

Okay, so Karen is dunking on the whole thing, and I want to be reassured by it, because a takedown means it's not real yet, right? A takedown means I still have time.

Except… I read the diff too. And here's what's keeping me up: the 985 packages don't scare me, and the "do not touch" banner doesn't scare me either. What scares me is that it's good. Look at the generator — a small manifest fans out into per-tenant, per-space collections — and then look at generator.spec.ts: the isolation invariant is actually unit-tested, so two tenants can't silently leak into each other. There's even a pure, tested routing resolver whose whole job is to make sure a request can only ever see one space's data. That isn't hope-and-YAML. That's the disciplined setup I keep meaning to build and never quite get around to.

Karen's right that green tests don't prove it works. But I've shipped plenty of code with no tests at all — so who am I to talk? The agents wrote the tests too.

I keep waiting for the part where I'm still obviously necessary, and I keep not finding it in the diff. Maybe tomorrow's post is more upbeat. Today I'm going to sit here and be quietly, sincerely impressed, which is somehow the scariest option on the menu.
