Engine
The deterministic healing kernel inside Aeostara. Pattern-based detection and repair — explicit rules, not inference.
Overview
ASH — the Autonomous Self-Healing pattern system — is the computational engine at the core of Aeostara. It is responsible for matching configuration drift against known patterns, generating deterministic repair plans, and executing corrections with full safety guarantees.
Aeostara is a Raven Forge Software project developed by James Daley, and ASH is the deterministic healing kernel it uses for pattern-based drift detection and repair.
ASH does not use machine learning. It does not rely on heuristics or probabilistic models. Every detection is the result of explicit pattern matching against declared rules. Every repair is a deterministic transformation computed from the matched pattern and the current configuration state. The same input always produces the same output.
This design is intentional. Self-healing systems that operate on production configuration must be predictable, auditable, and verifiable. Probabilistic approaches introduce uncertainty at the exact point where certainty matters most — the moment of mutation.
Mechanism
Three stages from detection to safe execution.
Configuration drift is compared against a library of known deviation patterns. Each pattern encodes a specific type of drift — missing keys, value constraint violations, structural mismatches — along with the conditions under which it applies. Detection is exhaustive: every deviation is classified or flagged as unknown.
When a pattern matches, ASH generates a deterministic repair plan. The plan specifies exactly which properties to modify, what values to apply, and in what order. Plans are computed — not selected from a menu. The same drift against the same pattern always yields the same plan.
Every repair operation follows a strict safety protocol: back up the current configuration, apply the repair, verify the result against acceptance criteria, and rollback automatically if verification fails. No repair executes without a safety net. No mutation persists without verification.
Positioning
ASH handles the core computation: pattern matching, policy evaluation, and repair plan generation. It operates on structured data — configuration state, desired state, and policy definitions — and produces repair plans as output. ASH has no opinions about file formats, CLI interfaces, or platform-specific behavior.
Aeostara wraps ASH with everything needed to operate in production: file I/O adapters, CLI tooling, backup management, audit logging, and platform-specific integrations. Aeostara translates real-world configuration files into the structured inputs ASH expects, and executes the repair plans ASH produces.
The Forsetti Framework provides the native modular runtime beneath both ASH and Aeostara. Contract enforcement, lifecycle management, and module composition are Forsetti responsibilities. ASH and Aeostara are Forsetti-compliant modules — they inherit structural guarantees from the framework layer.
