σ-gate

The protocol made executable: a deterministic coherence and trust gate for AI systems - declared output measured against what is safe to realize.

σ-gate is the operational layer of the Spektre protocol - the point where 1 = 1 stops being a theorem and becomes running code.

It is a deterministic trust gate for AI and agent output: leaked secrets, prompt-injection, and structural-coherence failures are caught without a model and without a network call, returning the same verdict every time.

The open core ships as a zero-dependency library; coherence (σ) scoring is available as a hosted service.

Where the corpus proves the theory and the protocol formalizes it, σ-gate enforces it.

  • Deterministic secret-leak detection — zero model calls, zero network round-trip
  • Prompt-injection & jailbreak interception before AI output lands
  • Structural coherence (σ) scoring: declared vs. realized alignment
  • Microsecond-scale per call (benchmark in the repo) — drop-in for any agent or CI pipeline
  • Open core ships as a zero-dependency library; hosted σ API available

A unified theory of coherence: the conditions under which any system - quantum, biological, institutional, or cosmological - maintains structure or collapses.
