 # Changelog
 
+## Unreleased — March/April provenance correction
+
+### Record identity and physical metadata
+
+- Promoted historical `2026.03.04(214.0).mp4` from the unresolved provenance
+  subtree as the true `2026-03-04 14:21` BallpointPen / Ink / Paper / 9x12
+  Standard record. Its 6,587,685,497-byte payload receives a new stable record
+  ID based on its former archival path.
+- Corrected the distinct 496,296,535-byte object formerly occupying that path
+  to `2026-04-04 16:49` after curator verification against the physical work.
+  Its existing stable record ID remains attached to the same media object.
+- Increased active membership to 339 Standard plus 129 Pre-Standard records;
+  no video bytes were added to repository storage.
+- Preserved the immutable `v0.3.0` tag at its original 467-record commit.
+
+### Media payload
+
+- Moved both existing Hub objects server-side without transcoding, replacing,
+  downloading in full, or uploading video bytes.
+- Removed the resolved `Unresolved_Series_9x12/2026.03.04(214.0).mp4` path only
+  after preserving that same object at its corrected canonical path.
+- No audio stream was modified.
