• FPGA DONE polarity fix: read_runtime() now inverts the active-low DONE pins, so a set FpgaDone.F1 means F1 is configured.
• New predicate commands for shell scripts: cm-is-cm-power-on, cm-is-fpga-programmed [F1|F2], cm-is-cm-healthy, cm-is-rtc-set and cm-wait-cm-power-on.
  • They exit 0 = yes, 1 = no, 2 = unknown.
  • Each prints one line; -q silences it.
• cm-exercise-mcu removed:
  • Reads are now only in cm-mcu-dump.
  • Writes moved to the new cm-mcu-control, which prints help listing all Control-page commands when given no action.
• cm-lga80d-snapshot-reset NAME?|--all: resets the LGA80D SNAPSHOT fault history. It only runs when power is POWER_OFF and asks for confirmation unless --yes.
• Readable MCU dumps: enums and flags print as names, e.g. POWER_ON (10) or A, B (0x03), instead of Python reprs, which differ between Python versions.
• Dump headers: every dump now records the MCU power state and FPGA DONE state.
• Versioning:
  • The RPM build writes the release tag into cm_interface.__version__.
  • Every tool has --version, and dump headers include the version.
  • CI fails if the installed version doesn't match the tag.
• Docs:
  • README, EXAMPLES, TODO and tests/hw/README.md updated for the new commands.
  • The README's description of the RPM workflow corrected.
  • MCU_REGISTER_MAP.md now uses the real CLI command names (pwr clearfail, alm clear, zmon on/off).
