- main.c: file-header comment describing the hardware and operation, logic split into named phases (sleep_until_interrupt, wake_peripheral_rails, take_counts_snapshot, send_wheel_counts_report, handle_minute_alarm, init_all_hardware); shared state renamed to say what it is and made static. - rfm69.c: reorganized into six labeled sections; cond_1/2/3 and hash scratch globals replaced by a reply_acknowledges() helper with clear locals; packet layout and every init register write documented. - LOG() macro (compiled out when DO_UART is off) replaces the #if DO_UART blocks that obscured the logic. - Drivers: file-header comments; named RTC_REG_*/RTC_ALM_MASK_BIT constants; EEPROM spool scheme documented; ADC_CHANNEL_BANDGAP named; repeated pin if/else helpers collapsed to SET_PIN_TO(). - Removed unused globals/buffers and commented-out code; ran clang-format with the project style. Register writes and radio protocol are byte-identical. Builds clean under -Wall -Wextra on gnu17 and c23; flash 13028 -> 12830 B, static RAM 1038 -> 999 B.
