security research · by request

Scoped work on trust infrastructure.

Scoped security research and review for signing, release and verification systems: validate vulnerabilities, define checks and prepare coordinated disclosures.

Services are separate from the semantic LMV toolkit, which remains in private development / pre-release. Engaging on services is not access to the product, and nothing here implies a release date. Capacity is limited; scope stays realistic.

Trust infrastructure review

Security assessment of signing, provenance and authorization infrastructure.

Architecture advisory

Scoped advisory and integration support for semantic verification in real signing flows.

How the research is done

A vulnerability research workflow for trust infrastructure. Used in this research practice; not offered here as a public software release.

capabilities

  • Automated hunting pipelinestatic analysis + semantic patterns
  • Candidate validationonline checks
  • Proof generationsubmission workflows
  • Disclosure trackingcoordinated

focus areas

  • Signature verification bypasses
  • Boundary handling errors
  • Authorization gaps
  • Resource exhaustion risks

This workflow is used in the research practice and is separate from the private/pre-release semantic LMV implementation. The research record documents public outcomes, not a validation of the workflow itself.

Engagement model

  1. Initial conversation to understand needs.
  2. Scoping and proposal.
  3. Engagement with defined deliverables.
  4. Delivery and written handoff.

Pricing: scoped per engagement. Coordination: async-first and written; an intro call only if it is useful.

Include your system or stack, the point where a check is needed, and the risk or question to investigate. Do not send secrets, private keys or sensitive production data. The first discussion establishes applicability and scope; product access is separate.
