MicroPython runtime vulnerabilities — Blockclock mini

The runtime-level security issues that come from the MicroPython interpreter and its bundled TLS stack, as opposed to the app-layer protocol weaknesses documented in SECURITY_ANALYSIS.md (cleartext CBOR/TCP, unsigned replies). These are the issues that could let someone own the box, not just spoof what it displays.

"""Show the Coldcard entropy-hack stolen BTC total on a BTClock.

Two public trackers publish a total; they measure different things:

  watch    coldcardwatch.com -- what was *stolen*. Sum of
           min(live_balance, attributed) over the 7 collector addresses,
           plus a snapshot of the wave-3 vaults. The attribution cap means
           the figure is a verified minimum and can only fall.

#!/usr/bin/env python3
"""Show USB-C adapter load + system power via Apple SMC.

Auto-detects sysfs base (legacy applesmc.<N> on pre-T2, ACPI APP0001:00 on T2)
and SMC endianness (T2 stores ui/si little-endian; sp* and flt stay big- and
little-endian respectively on all Apple SMC variants).

Usage:
  smc-power.py            # one-shot
  smc-power.py --watch    # live every 1s (Ctrl-C to stop)
