We also asked if collaborating with iFixit for this process was an easy decision, or if it required winning over any internal stakeholders who might have been skeptical about the partnership. Christoph says, “Was there skepticism internally? Of course. Inviting an external expert into the development process, especially one known for being direct and uncompromising, naturally raised concerns. Teams worried about added complexity, design constraints, and the perception that we were exposing ourselves to criticism.

This does not mean confusables.txt is wrong. It means confusables.txt is a visual-similarity claim that has never been empirically validated at scale. Many entries map characters to the same abstract target under NFKC decomposition (mathematical bold A to A, for instance), and the mapping is semantically correct even if the glyphs look nothing alike. But if you treat every confusables.txt entry as equally dangerous for UI security, you are generating massive false positive rates for 96.5% of the dataset.
The 386 solves this by repurposing RPT (Repeat). Normally, RPT implements loops -- it re-executes a micro-instruction while decrementing a counter, as we saw in the multiplication post. But when a protection test is in flight, the hardware suppresses RPT's counter-decrement and turns it into a pure stall: the sequencer freezes until the PLA result arrives.
