#  WiFi-DensePose: Trust Kill Switch
#
#  One-command proof replay that makes "it is mocked" a falsifiable,
#  measurable claim that fails against evidence.
#
#  Usage:
#    ./verify           Run the full proof pipeline
#    ./verify --verbose  Show detailed feature statistics
#    ./verify --audit    Also scan codebase for mock/random patterns
#
#  Exit codes:
#    0  PASS  -- pipeline hash matches published expected hash
#    1  FAIL  -- hash mismatch or error
#    2  SKIP  -- no expected hash file to compare against
# ======================================================================
