+# DDR Workflow
+
+Raw DDR is generated input and belongs beside the client project, outside the AI workspace Git repository. Parsed DDR is useful for diffs and analysis, but only after a security review.
+
+## Portable project layout
+
+```text
+<client>/<project>/
+  ddr/
+    dev/
+    prod/
+    archive/
+  <project>-ai/
+    DDR-Parsed/
+```
+
+Projects should store relative source definitions, not absolute workstation paths. A future parser wrapper must validate the source, parse into a temporary directory, run redaction checks, and only then update `DDR-Parsed/`.
+
+Do not enable automatic commits from the parser. Review the sanitized diff before committing it.
