# Realizable

Evaluates execution feasibility of a plan

Layer: Mind · Category: Reasoning

## Mechanism

A [Judge](https://mindscape.pages.dev/bootstrap/Judge.md) of execution feasibility: can the declared artifact actually be built or enacted in the world it targets, given its stated inputs, [Step](https://mindscape.pages.dev/bootstrap/Step.md)s, and constraints? Applies wherever a [Plan](https://mindscape.pages.dev/bootstrap/Plan.md) or design must be checked against physical, computational, or institutional reality — engineering feasibility, policy implementation, software design, research program scoping. The essential move is grounding every [Step](https://mindscape.pages.dev/bootstrap/Step.md) in a primitive or sub-component that is itself realizable, recursively. Specific rating semantics belong on descendants or on the composing protocol. The signature Judge([Value](https://mindscape.pages.dev/bootstrap/Value.md)) captures that the question yields a [Value](https://mindscape.pages.dev/bootstrap/Value.md)-rating of feasibility, not a binary verdict — 'mostly realizable with two unverified links' is a legitimate output.

## Invariants

- Causality: no [Step](https://mindscape.pages.dev/bootstrap/Step.md) precedes its dependencies. Topological order, not sequence — independent steps may run concurrently.
- Every leaf terminates in a primitive drawn from a stated set of what is available.
- The verdict is rendered against a stated [Budget](https://mindscape.pages.dev/bootstrap/Budget.md) and names it.

## Failure modes

- Hidden Complexity: A step looks simple ('Draw the rest of the owl') but contains unsolved sub-problems.
- Resource Blindness: The steps are logically sound but physically impossible given the budget.

## Signature

- `Judge(Value)`
