# Migration: v1.64.0.0 — repair Chrome-for-Testing bundles poisoned by the
# old in-place rebrand (#2242).
#
# Why a migration: pre-v1.64 launchHeaded() rewrote the Chromium .app's
# Info.plist ("Google Chrome for Testing" → "GStack Browser") and overwrote
# its Resources/*.icns — inside the SHARED Playwright cache. That broke the
# codesign seal (GPU process exit_code=5; headed mode dead on macOS 26) and
# poisoned the cache for the user's OTHER Playwright projects too. Deleting
# the rebrand code fixes fresh installs only; every existing macOS install
# still has the mutated bundle on disk. This migration removes poisoned
# bundles and re-fetches a clean one so the upgrade doesn't leave the user
# with zero working browser (the browse launch path also self-heals, as the
# belt to this suspenders, for installs that never run migrations).
#
# Affected: macOS installs that ever ran headed mode before v1.64.
#
# Idempotent: detection is content-based (plist contains "GStack Browser");
# a clean cache is a no-op, and the .done touchfile gates re-runs. The
# re-fetch is best-effort and non-fatal per the migration contract.
