# Task 1658 — standing voice-mirror capability audit across every brand.
#
# Reconciles *advertised* (voice-mirror ships as a core plugin: its PLUGIN.md
# is present in the source tree) against *installed* (the brand does not
# exclude it from the bundle AND the manifest declares the full tool set) for
# each brand under maxy-code/brands/. Platform plugins ship subtractively —
# the bundler copies all of platform/plugins/ except a brand's plugins.excluded
# list — so "installed" keys on that exclusion, matching what the manager's
# loadToolSurface enumerates at boot.
#
# Emits one line per brand:
#   [voice-mirror-audit] brand=<slug> advertised=<yes|no> installed=<yes|no>
#
# advertised=yes installed=no is the pre-1652 failure state. It must appear for
# no brand; if it does, this script exits non-zero.
