+## Built-in transcript or bounds source is unavailable
+
+Symptom:
+
+- analyze, extract, render, or publish says a built-in source is unavailable
+  even though a file exists at its usual session path.
+
+Likely cause:
+
+- the producing stage has not succeeded, its output lacks the exact registered
+  source, run ID, or checksum, its evidence is duplicated or stale, or the
+  durable bytes no longer match the manifest checksum.
+
+Safe fix:
+
+- do not copy or rename the file to make it discoverable. Rerun the producing
+  stage to regenerate both the bytes and current manifest evidence, then retry
+  the consumer.

 ## Legacy aggregate analysis requires regeneration
