Build and test
Project-specific verification, often exposed as AXF capabilities so agents do not guess commands.
Control Deck
Gates decide whether work advances.
A gate is a check that converts agent intent into a reviewable state: pass, fail, blocked, escalated, or skipped by policy.
Common gates
Policy
Module boundaries, forbidden edges, scope limits, and other Lex policy checks.
Authority
LexThority decisions for effects such as pushing, deploying, exporting, deleting, or mutating shared systems.
Human review
Escalation when risk, missing context, or organizational policy requires an operator decision.
Runner boundary
LexRunner should run and collect gates. It should not own every gate's meaning. Capability checks, policy checks, authority decisions, and human approvals remain separate surfaces.
