/**
 * AUQ behavioral matrix — drive each AUQ-heavy skill to its first
 * AskUserQuestion and grade it to plan-ceo's bar (periodic, paid, SDK capture).
 *
 * Layer 0 (auq-format-always-loaded.test.ts) deterministically guarantees every
 * skill SHIPS the format spec in its always-loaded skeleton. This test proves
 * each skill's model OBEYS it: that the first real AUQ each skill fires is a
 * compliant decision brief (all 7 format elements) with a substantive
 * recommendation (>= 4). One parametrized case per skill so a single weak skill
 * is an isolated failure, not a blocker for the rest.
 *
 * Capture is the SDK $OUT_FILE path (clean text, no TTY mangling), with the skill
 * pinned to an absolute path and the agent restricted to Read/Write so it can't
 * wander to the global install. See test/helpers/auq-sdk-capture.ts.
 *
 * Scope: skills whose first AUQ is reliably reachable from a text fixture. Skills
 * that gate their first decision on external resources (a running browser for
 * /qa, the design binary + comparison boards for /design-shotgun and
 * /design-html — which by project policy use $D compare, not AUQ, for variant
 * choices) are intentionally OUT of this matrix; Layer 0 covers their format
 * spec, and a fixture can't fairly trigger their AUQ.
 *
 * Run a subset in the foreground with AUQ_MATRIX_ONLY="plan-eng-review,cso".

## Goal
Increase developer adoption.

## Success metric
More signups.

## Premise
We haven't talked to any developers about whether price is the barrier. The team
agreed it "feels like" it should be cheaper. We'll add a new Stripe tier, a React
pricing page, a Postgres entitlements table, and a Redis cache — no tests
mentioned, no rollout plan, no auth check on the upgrade endpoint.
