How to reason about state in an interface codebase before writing any component. Interfaces are functions from state to screen, so the discipline is enumerating legal states in types, not minimizing branches. Covers boolean-to-union collapse with exhaustive switches, where the compiler stops seeing (RPCs, env vars, casts), tracing every control to the predicate it changes, deriving values instead of mirroring them, the feature-flag lifecycle (one read, two trees, a removal owner), and…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Factory state modeling Each section leads with **Principle** (one sentence, stack-agnostic), then **Why** (constraint, option, tradeoff), then **Recipe** (the React + TypeScript shape we use), and **Failure mode** where one has been observed. `factory-frontend` owns CRUD recipes; this skill owns the reasoning layer those recipes depend on. ## Interfaces are state to screen, not input to output **Principle.** An interface program never exits; its whole job is choosing what to show for the current state, so branching over state is the product, not overhead. **Why.** A pipeline runs once from input to output. Every branch there is a path the data might take and costs twice: once at runtime across every record, once in your head when tracing what happened. Less code is better because the program has one job. An interface is a different kind of program. It is re-run on every state change, and "given this user, role, device, selection and pending request, what is visible" is the entire specification. Engineers arriving from scripts carry the minimize-code instinct into UI and express state as a handful of ad hoc booleans "to keep it simple." The result is fewer lines and more… …

How to install
mdr add nonlinear-xyz/factory-kit/factory-state-modeling@sha256:2925d308987ab1eeThe line at the top of this page pins the label git:20261029.d37b2cc, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
