side-effect-isolation
Enforce side-effect isolation: identify side effects, move them to boundary adapters/effects, keep Domain pure, and keep UI declarative with signals.
signals-first
Enforce 'Signals first, streams when needed' in a change: keep UI state as signals, isolate streams to boundaries, and convert Observables at the Application/facade boundary.
single-responsibility
Apply SRP to a change request: identify mixed responsibilities, propose the smallest split, and keep interfaces minimal (paired with Occam/tool-first).
tool-first-assembly
Apply Tool-First, Then Assembly during implementation: extract the smallest reusable tool(s) first, then wire them via assembly in outer layers without increasing coupling.
unidirectional-data-flow
Enforce unidirectional data flow in a change: define explicit commands, keep writes in Application, expose state via signals, and isolate side effects at boundaries.
