Concepts

The single human person for whom Res exists. Res is a first-person system — it models one individual's life, actions, and intentions, not those of teams or organisations. Everything else in the model is defined relative to the individual.

What is. Reality is what the individual experiences — mediated by the senses and shaped by the limits of perception, yet no less real for being mediated. Res does not pretend to a god's-eye view of the world; it models the world as the individual encounters it.

The rules of inference that turn data into conclusions, predictions, and plans. Deduction, induction, abduction — the structures of valid reasoning. Logic is inherent to the human experience; the individual cannot think without it, even when thinking badly. It is what allows beliefs to be grounded and goals to follow from values.

Anything the individual does. The atomic unit of human output. Thinking is an action, deciding is an action, writing is an action — all of them produce something that can become input to the next.

The unstructured stream of reflection that runs through the individual's mind — ideas, deductions, half-formed observations. Thoughts are private and fleeting by default; they become useful when externalised. The inbox is where they are captured before they are processed into beliefs, goals, tasks, knowledge, or discarded.

What the individual holds to be true and worth pursuing — claims about the world, about themselves, and about what is good. Beliefs are the ground from which goals arise. Object-level only: the foundational axioms that justify Res itself live in the Foundations document.

Desired future states the individual wants to bring about. Goals describe what should be true, not what to do. Each has an objective and zero or more key results — evidence that the objective has been reached.

A bounded set of work directed at a goal. A project has a scope and a condition under which it is complete. Its purpose is to give tasks context — to keep them tied to an intention rather than floating free.

A planned action — a single action the individual intends to perform, defined precisely enough to be executable. Tasks are the primary unit of work within Res: where intention meets the calendar.

The record of what the individual actually did. An action has a time, it happened, and it is immutable once recorded. The word is used at two levels in this model — the philosophical primitive (anything the individual does) and this operational layer (the logged event below a task). The two should be kept clear.

A persistent domain of the individual's life. Goals, projects, tasks, and data can belong to an area. Areas are not bounded or completable — they are ongoing dimensions of living. They are user-defined: Res does not hard-code them.

Everything received and recorded. Sensory inputs the individual takes in, measurements logged from instruments, observations written down — all of it is data. It accumulates indefinitely, points backward or sideways in time, and feeds back into beliefs and decisions. Lightweight trackers cover ad-hoc metrics; first-class domains (sleep, exercise, finances) get dedicated schemas when they earn the commitment.

The unidirectional dimension along which actions occur. The individual can act only in the present moment. The past is fixed and accessible only through memory; the future, only through prediction and planning. Every layer of the hierarchy lives in time; nothing escapes it.
