#  WiFi-DensePose / RuView — Trust Kill Switch
#
#  One-command proof replay across every layer of the stack:
#    1. Python signal-processing pipeline (the original v1 proof)
#    2. Production-code mock scan (np.random.rand/randn in non-test paths)
#    3. Rust workspace tests (cargo test --workspace --no-default-features)
#    4. PyO3 BFLD binding (cargo check -p wifi-densepose-py)
#    5. ADR-125 §2.1.d invariant — identity_risk_score never crosses
#    6. Published crates.io tarball SHAs
#    7. Published npm packages
#    8. Published Docker image multi-arch manifest
#    9. Embedded HOMECORE binary in the Docker image (homecore-server)
#
#  Usage:
#    ./verify                Run every phase.
#    ./verify --quick        Skip slow phases (cargo test, docker pull).
#    ./verify --rust-only    Only the Rust workspace test phase.
#    ./verify --docker-only  Only the Docker manifest + binary phase.
#    ./verify --verbose      Show detailed feature stats in the Python proof.
#    ./verify --audit        Also scan codebase for mock/random patterns.
#    ./verify --generate-hash  Regenerate the v1 expected hash (rare).
#
#  Exit codes:
#    0  ALL PHASES PASS (or SKIP gracefully when optional deps missing)
#    1  Any phase that ran returned FAIL
#    2  Phase 1 was forced to SKIP (no expected hash file)
