+## Capture Rules
+
+- Record only public URLs or generic sent-channel notes such as
+  `sent via email to hiring contact` or `shared in private DM`.
+- Do not record recipient names, email addresses, private profile URLs, message
+  contents from replies, or anything copied from a real workspace.
+- Keep every entry tied to the sanitized Northstar Labs demo package.
+- If an artifact is regenerated before posting, rerun the pre-publish checklist
+  in [portfolio-handoff-bundle.md](./portfolio-handoff-bundle.md) before marking
+  a channel as published.
