Three things the hardware offers that the code ignored. The joystick has never had a line of code. Left records a dry label, right a wet one, middle cycles the LED scene, and a full-panel flash acknowledges the press because a headless box gives no other sign and a button you cannot tell worked gets pressed twice. Precipitation is the weakest head in the bank and strong labels are its binding constraint: this station has 80 of them against thousands of proxy ones, entirely because the only label control lives in a web page, and a web page is not where anyone is standing when it starts raining. The board has no RTC, so a power cut without a network gives a clock somewhere in 1970 on the next boot. Solar elevation, the diurnal harmonics and a sample's position on the 5-minute grid then all lie with complete confidence, and unlike a gap in the record the damage cannot be identified afterwards. train() now refuses a clock below 2025 or one that has stepped behind the newest stored row, and logs the refusal rather than training on fiction. Undervoltage and thermal capping both shift the SoC temperature, which is the regressor in the self-heating compensation, so a weak power supply presents as an unexplained temperature bias rather than as anything resembling a power problem. get_throttled is now sampled hourly and logged when set. Measured and deliberately not done: colour features. r, g and b are logged and 74% of rows carry usable colour, but adding blue/red, green/red and saturation made MAE 1.50% worse and helped in only 13 of 72 cases. Three more regressors on a 33-feature model whose longest horizon trains on 13 independent pairs is straightforwardly overfitting. That also prompted a sweep of the RLS prior and forgetting factor in both directions; delta = 100 with lambda = 0.9985 is a local optimum on both axes, so neither moved.
