Subject: [PATCH 01/17] CI-in-preview prototype: OIDC verifier,
 encrypt-override route, smoke workflow

Test the "authenticated work lives in deployment, not CI" pattern end-to-end
with the smallest useful scope: CI mints a GitHub Actions OIDC token, hits a
preview-only route in v0chat, and the route uses FLAGS_SECRET from the preview
environment to encrypt a flag override cookie. No secret is mirrored in GH.

ERR_PNPM_LOCKFILE_CONFIG_MISMATCH Investigation

Reference: pm-core-explainer.md for the conceptual model (signal hierarchy, coherence, the three-phase pipeline).

The Goal

We want v0 to do less bespoke shit. This means:

1. Align with Vercel platform behavior: if a project builds on platform, it

Temporal Blindness + Clock-Sure Confidence Pattern

For Mauricio's code generator work

The Problem

LLMs experience time like colorblindness - systematically wrong but feeling certain. Claude confidently says "last month" when it was 6 months ago, or "just discussed" when it was 3 conversations back.

The Framework as Opt-Out: How Complexity Theories Enable Antisocial Engineering

The Pattern

Grand theories of software complexity (Simple Made Easy, Out of the Tarpit) create intellectual frameworks that let their adherents opt out of shared solutions while feeling superior about it.

The mechanism:

1. Create a taxonomy - Simple vs Easy, Essential vs Accidental

Getter-Only Auto-Accessor Decorators

Broadly speaking, the idea is that you should be able to create an accessor decorator that doesn't expose a setter.

I think the most natural way to express this is for the set function returned by an accessor decorator to have a never return type. The idea is that such a decorator would result in the type system treating the resulting field as if it was a manually written getter without a setter.

Here's an example scenario:

import { Friend } from "hypothetical-lib";
