Visual Context

Architecture pages define ownership, authority, and dependency direction for the base design.

Reading Checklist

Question	Where to look
Who owns the semantic decision?	Check the authority and boundary language.
What is platform-neutral?	Find Aeostara-owned obligations.
What moves downstream?	Find adapter, implementation, and deviation rules.

Native Target Architecture

Architecture Layers

1. Upstream semantic authority (ASH)
2. Downstream conformance/orchestration (Aeostara)
3. Platform-native realization (Windows/macOS/iOS)

Aeostara Layer Responsibilities

• Observe runtime/product state
• Normalize and map to ASH-aligned state representation
• Evaluate diagnostics/classification/recoverability using ASH semantics
• Build recovery plans with deterministic gating
• Execute and verify actuator steps with backup/rollback/audit
• Escalate via fallback, containment, and safe-halt pathways

Platform Layer Responsibilities

• Implement adapters/services using native frameworks/toolchains
• Preserve deterministic behavior and interface contracts
• Provide platform-specific observability and operations integration

Semantic Constraint

Platform differences may change implementation details but cannot change state-class meaning, recovery category semantics, or escalation rules.
