ASA — Atomic Slice Architecture

An architecture standard for AI-generated software that stays maintainable. ASA defines how code should be structured when AI generates it — slice isolation, boundary enforcement, and deterministic regeneration.

No vendor. No license. No cost.


Four Core Principles

1. Determinism

Same input, same output, always. Every ASA operation produces identical results — no randomness, no heuristics, no AI inference in the core pipeline.

2. Zero Magic

Explicit over implicit. No hidden behavior, no automatic assumptions, no context-dependent defaults.

3. Boundary Enforcement

Slices are isolated units. They cannot import from other slices. Cross-domain dependencies are forbidden and caught by the linter.

4. Marker-Based Preservation

When a spec changes, the slice regenerates predictably. Custom code between markers is preserved. Structure updates, logic survives.



Start Here

ASA is designed for incremental adoption. You don't migrate — you start using it for new features.
