# LAKA Volumetric Security Grammar > A defensive, authorization-first security grammar: the SECURITY_UNIT model, a volumetric matrix of variables × meta-variables × five change levels, hardening grammars for drives, VPS hosts, web applications and containers, plus schemas, worked examples, a deny-first policy and a machine-checkable authorization gate. Version 1.0.0, reviewed 2026-09-03. 15 chapters, 8 JSON Schemas, 7 worked examples, 16 SECURITY_UNIT components, 10 internal variables × 14 meta-variables × 5 change levels, 9 deny rules, 10 adopted standards. Boundaries: A specification and reference set — not an attack tool, a scanner, a certification or a completed assessment. It does not automate exploitation. Active or state-changing operations require a valid authorization manifest, an in-scope target, an allowed mode, verified preconditions and verified rollback. ## API Base URL: https://security.bowtiekreative.com OpenAPI: https://security.bowtiekreative.com/v1/openapi.json Index: https://security.bowtiekreative.com/v1 Read: - https://security.bowtiekreative.com/v1 — This index - https://security.bowtiekreative.com/v1/health — Liveness and corpus counts - https://security.bowtiekreative.com/v1/openapi.json — OpenAPI 3.1 description of this API - https://security.bowtiekreative.com/v1/manifest — Package manifest, inventory and boundaries - https://security.bowtiekreative.com/v1/unit — The SECURITY_UNIT model and the governing production rule - https://security.bowtiekreative.com/v1/matrix — The volumetric matrix: variables, meta-variables and five change levels - https://security.bowtiekreative.com/v1/schemas — The eight JSON Schemas, listed - https://security.bowtiekreative.com/v1/schemas/{name} — One schema in full, e.g. finding - https://security.bowtiekreative.com/v1/deny-rules — The deny-first policy rules - https://security.bowtiekreative.com/v1/standards — The adopted, version-pinned standards register - https://security.bowtiekreative.com/v1/tools — Registered tool classes — names and safety posture only - https://security.bowtiekreative.com/v1/examples — The worked example documents, listed - https://security.bowtiekreative.com/v1/examples/{id} — One example: JSON document plus YAML original - https://security.bowtiekreative.com/v1/docs — The fifteen chapters, listed - https://security.bowtiekreative.com/v1/docs/{slug} — One chapter, as markdown - https://security.bowtiekreative.com/v1/sources — Standards and chapter sources Decide: - POST https://security.bowtiekreative.com/v1/validate — check {schema, document} against one of the 8 published schemas. Structural validity only. - POST https://security.bowtiekreative.com/v1/authorize-check — evaluate the governing authorization rule; missing gates count as false and the default is deny.

It documents how to describe, gate and evidence security work — it does not automate exploitation, and no endpoint here performs scanning, testing or change. Active operations in the real world require a valid authorization manifest, an in-scope target, an allowed mode, verified preconditions and verified rollback.
