Flow (AIM sense)
Canonical definition
Flow is the low-crowding limit of Observer-driven crowding-out of the Thinker's generative search: the state in which few observable valuing agents are present in the field, or the Observer is rendered low-Salience with respect to those present, so that the Observer's continuous sampling of the Belief Register and of the behaviour of observed agents falls toward its minimum and ceases to compete with Imagination's goal-directed search of the Hypothesis Space. Flow is not a distinct architectural state or a separate mechanism; it is the low-intensity end of the single continuous crowding-out process whose high-intensity end is dense Observer sampling of many Salient valuing agents. Its two signature features are one condition described on two channels: loss of self-consciousness is the minimum of Observer crowding on the self-as-observed-agent channel, and subjective time compression is the same minimum on the duration-tracking channel, because subjective duration tracks the density of registered agent-configuration events (the Observer's dominant input under the Configural Update-Rate Asymmetry), so that stream thinning and felt-time compressing are the same event. The enjoyment of flow is the joy in the doing at its most concentrated: each stage of the process closes its own deficit as the work proceeds, and with the Observer quiescent nothing competes with the liking those closures carry (Chapter 4, Section 4.3.2).
Explanation
Flow is what happens when there is almost nobody to watch and nothing agent-like to keep track of, so the part of your mind that constantly monitors other people and where you stand relative to them goes quiet, and the thinking-and-imagining part is left free to work on the task in front of it. This is why flow needs a clear goal and a good skill-challenge match: the imagination stays pointed at the task the whole time; quiescence only removes the social monitoring that would otherwise distract it. The two famous features of flow (losing your sense of self and losing your sense of time) are not two separate things. They are the same quiet-Observer condition showing up in two places: you stop tracking yourself as someone being watched and judged, and, because your brain measures time by counting notable happenings and the most notable happenings are other agents doing things, there is suddenly almost nothing left to count, so time seems to vanish. The enjoyment comes from the work itself: each small step that comes right is a small satisfaction, and with nothing else competing for attention those satisfactions are what you feel. Flow is the individual, moment-to-moment version of the same crowding-out that shows up when a paid reward kills someone's enjoyment of an activity (Motivation Crowding-Out) or when a status economy squeezes out genuine-interest activity across a whole society (the I-Crowding-Out Dynamic).

Framework-Specific Construct. Derived as the low-crowding limit of the Observer-Quiescence Corollary. Externally corroborated by flow research (Csikszentmihalyi), active-inference accounts of flow's self-loss (Parvizi-Wayne et al.), the event-density account of time perception (Block and Grondin), and Event Segmentation Theory (Zacks and Swallow).
