MKTT-WP-0009: Access-Controlled Knowledge Gateway

Purpose

Add a policy boundary for cached retrieval and context packages so Markitect can support security-sensitive knowledge systems and agent workflows.

P9.1 - Define access-control ladder

id: MKTT-WP-0009-T001
status: todo
priority: high
state_hub_task_id: "acf240b4-7210-4ee5-90b6-2f2fe1438439"

Specify supported modes:

• labels and trust zones
• path/file ACLs
• relationship-based access control
• attribute/rule-based policies
• external policy engines

P9.2 - Implement local label policy

id: MKTT-WP-0009-T002
status: todo
priority: high
state_hub_task_id: "9eb589d2-82f2-4282-9af0-3958826d397d"

Start with local policy labels and diagnostics for denied or redacted results.

P9.3 - Add policy-aware query filtering

id: MKTT-WP-0009-T003
status: todo
priority: high
state_hub_task_id: "d78ab623-c472-4b24-ad84-08464b574886"

Ensure results are filtered before leaving the backend boundary. Result metadata must report whether policy filtering occurred.

P9.4 - Add relationship policy adapter design

id: MKTT-WP-0009-T004
status: todo
priority: medium
state_hub_task_id: "bd4c2b7a-6eac-4845-b5c8-9f9c64946f0c"

Design an adapter boundary for Zanzibar/OpenFGA/SpiceDB-style relationship checks without binding the core package to any one service.

P9.5 - Add rule policy adapter design

id: MKTT-WP-0009-T005
status: todo
priority: medium
state_hub_task_id: "752f1962-e83c-44cc-a1c1-0f89a4ea2a90"

Design an adapter boundary for OPA/Rego and Cedar-style rule policies.

P9.6 - Add decision logs and explainability

id: MKTT-WP-0009-T006
status: todo
priority: medium
state_hub_task_id: "990f01fa-5008-4871-a887-1c6ab4375605"

Record policy decisions with subject, action, object, context, decision, reason, and provenance.

Exit Criteria

• Local caches can operate in an explicit policy mode.
• Query and context package results are policy-aware.
• More rigid authorization engines can attach later without replacing the query/cache framework.
