+# Media analysis output must cite the source URL/timestamp for every claim — no unsourced assertions
+
+## What it says
+
+When an agent analyzes content from a media source (YouTube transcript, substack article, tweet, user-provided text), every claim in the output MUST cite the source: the URL, the timestamp (for video/audio), or the paragraph number (for text). Unsourced assertions are banned.
+
+## Why
+
+Media analysis without citations is indistinguishable from hallucination. The user cannot verify a claim like "the author argues X" without knowing where in the source the author said X. The citation is the provenance; without it, the analysis is unverifiable.
