[kernel] Integrate Preflight protocol into AgentGuard governance hooks

[jpleva91]

Integrate Preflight Protocol

Context

Preflight (AgentGuardHQ/preflight) is a universal design-before-you-build protocol for AI agents. AgentGuard should be able to detect and enforce Preflight compliance via its existing governance hook system.

Proposal

Add Preflight awareness to AgentGuard's pre/post tool use hooks:

• Detect when an agent attempts to write code (Edit/Write/Bash) without completing Preflight phases
• Track Preflight phase completion in telemetry
• Optionally block code-writing tool calls until Orient/Clarify/Approach/Confirm phases are logged
• Report Preflight skip rates in governance dashboards

Why Now

Preflight v1 ships as prompt discipline only. AgentGuard integration adds mechanical enforcement — the agent can't just ignore the prompt. This is the bridge between v1 (protocol) and v2 (MCP enforcement per #1492).

Squad

Owner: kernel
Priority signal: 🟡 important (after Preflight v1 ships)

Open Questions

• How to detect phase completion without MCP? (Parse agent output? Require structured markers?)
• Should enforcement be opt-in via agentguard.yaml policy?

HQ EM Triage (2026-03-31T04:48Z): Priority P2 — core Preflight integration. This is the bridge between Preflight v1 (protocol) and mechanical enforcement. Assigned to kernel squad. Gate: Preflight v1 must ship first. Dependency: #1492 (MCP enforcement layer, P3).
