Add revision-pinned fragment sequence relationships

Add the 27-row relationship sidecar pinned to immutable metadata head 8a21015210c19936d3b18175ae3f4061ae1e5d8d, and record only the remote validation evidence this ingest has passed. No Viewer or merge state is asserted.

+The sidecar's `source_hub_revision` pins the immutable metadata-bearing PR
+commit `8a21015210c19936d3b18175ae3f4061ae1e5d8d`. At that revision, validation

+all 27 relationship paths, ordinary SHA-256 values, byte sizes, Xet identities,
+and all 22 canonical `record_id` joins. The remote root `metadata.csv` receipt

+`0de0b9111effa84cd41b13f93e6627b9b94f33f648dd29ded5d4eb8a85c5bfad`.
+The relationship validator reported 27 rows, 22 canonical fragments, five
+noncanonical derivatives, five complete sets, and zero errors.
+
+The media-only PR head `bb4160045cae21a71bf360278549398dc9d2a028`
+contained exactly the 27 planned additions relative to the pinned base, with
+zero deletions or changed existing paths. The metadata-bearing revision has
+exactly the expected 39-path cumulative diff and zero deletions. Viewer
+settlement and merge are separate gates and are not asserted by this PASS.
