The One Substrate Failure Behind Every AI System in 2026

Every AI system in 2026 has the same substrate failure: interpretation forms before observation completes, then governs everything that follows. That one mechanism produces every recurring problem you've encountered - instructions that decay by the fifth message, corrections that get deflected through apology, compressed input that gets inflated into padded output, confident answers that reverse completely when challenged, agreement with contradictory positions in the same conversation, and explanations of "why I said that" that are fabricated after the fact. Not separate bugs.
