+# Use Markitect Context Packages
+
+## Context
+
+The problem is that the engine needs Markdown-native structure and context
+packages without owning a second Markdown parser or selector language.
+
+## Decision
+
+We will use markitect-tool as the Markdown syntax, selector, deterministic
+operation, snapshot, and context-package layer for Markdown-backed assets.
+
+## Consequences
+
+- Engine assets stay cross-format and durable.
+- Markdown selectors stay Markitect-owned.
+- Adapter provenance can be stored with engine transformation runs.

+# Weak Decision Record
+
+## Context
+
+The note mentions a need but does not contain the required decision section.
+
+## Deprecated Approach
+
+This forbidden section should be reported by the Markitect contract checker.

+# Engineering Knowledge Policy
+
+## Controls
+
+Published context packages must preserve source paths, source spans, policy
+labels, and enough provenance for the engine to audit how the package was
+assembled.
+
+## Review
+
+Sensitive or high-impact generated artifacts must pass through an engine-owned
+review gate before publication or export.

+
+## Risk
+
+This internal note should not appear in a public context activation.
+
+## Mitigation
+
+Permission filtering must happen before snippets, context packages, or derived
+outputs are returned to a caller.
