MARGINAL is provided under the Apache License 2.0. These terms clarify the public plugin experience and do not replace the license.
MARGINAL is experimental developer infrastructure. It is provided without a service-level agreement or guarantee of token savings, cost reduction, task success, uninterrupted operation, or suitability for a particular purpose. Shadow Mode is the default. Tool Enforcement is not a security boundary and fails open if the integration becomes unavailable.
Users remain responsible for reviewing Codex hook commands, granting trust, selecting policies, reviewing stop candidates, protecting local evidence, and validating generated work. Do not use MARGINAL as the sole control for safety-critical, legal, medical, financial, or production-access decisions.
Performance numbers must be interpreted with their published scope. The current three-task Codex
smoke returned pass_through; its observed token difference is not a general savings claim.
Third-party products and services, including Codex, GitHub, model providers, and plugin directory operators, have separate terms. SignalLayer Labs may update these terms by committing a dated revision to the canonical repository.
