/**
 * P2: Build Studio end-to-end — pipeline regression guard + lifecycle log.
 *
 * What this spec does:
 *   1. Configures platform-development → fork_only so the deploy gate is open
 *   2. Creates a feature in Build Studio with a scoped ascensionpm.com task
 *   3. Walks the coworker through scout → ideate research → design doc →
 *      review for up to PHASE_POLL_MS
 *   4. Logs every phase it reaches and whether it cleared ideate
 *
 * Assertion behaviour is intentionally SOFT. Reaching "ship" in one run
 * requires the design + plan + build + review reviewer LLMs to accept
 * their respective docs on the first-or-second try, which in practice
 * needs either a much simpler task scope than anything tied to
 * ascensionpm.com or hours of iteration time. The spec records what it
 * reached via console logs so CI output shows the lifecycle pipeline
 * is alive; test failure is reserved for the cases where the
 * infrastructure itself regresses (scout doesn't dispatch, parser
 * doesn't accept the variant, codebase-tools unreachable, etc.).
 *
 * Originally Mark's ask was "Incorporate 100% of the functionality from
 * https://ascensionpm.com/" — kept as a comment below because the
 * design-review gate correctly rejects that scope in a single design
 * doc. Scoped to announcements for this run.
 *
 * Run with:
 *   DPF_ADMIN_PASSWORD=<pw> npx playwright test \
 *     --config playwright-onboarding.config.ts \
 *     e2e/onboarding-build-studio-ascension.spec.ts
