Invariant Systems Structural diagnostics for adaptive systems
Structural Stability & Drift Audit

SSDA

The SSDA determines whether a system is structurally stable, marginally stable, drifting, locked, or operating outside valid learning regimes. The audit is diagnostic-only and uses behavioural evidence only.

Output

No fixes are prescribed. No tuning advice. No roadmap. The report is designed to be an epistemic boundary document.

Evidence intake (A–D)

  • A. Decision trace data: time-ordered records of decisions or outputs
  • B. Outcome / feedback signals: observed consequences, delays, missingness
  • C. Intervention & change logs: human/system changes over time
  • D. Contextual metadata: lightweight environment descriptors to test behavioural tracking

Explicit exclusions

  • No model internals (weights, activations, prompts, hidden state)
  • No source code review
  • No training data access
  • No proprietary features or internal schemas required

Requests for internals are treated as diagnostically meaningful, but they are not required for engagement.
