+## [0.75.0] - 2026-08-16
+
+### Changed
+
+- Related-node person chips include the affiliation organization when
+  exactly one distinct identity is known. After `make seed`, walking
+  from Demo Corp shows "Ada West, Demo Corp (Our side)". Priya Nair
+  has two unresolved orgs (Northridge Grid and Northridge Holdings),
+  so the chip stays "Priya Nair (Counterparty)" -- a second org is
+  never collapsed into an invented primary. When the one identity is
+  a resolved `corporate_entity`, the catalog `entity_name` is shown
+  rather than the raw extraction string. A person with no affiliation
+  keeps the side-only caption.
+
+## [0.74.0] - 2026-08-16
+
+### Changed
+
+- Related-node post chips show the post title only, not
+  "Linked post (Post)". Person and org chips already use business
+  labels; the ontology class on a post title was noise.
+
+## [0.73.0] - 2026-08-16
+
+### Changed
+
+- Related-node organization chips use the `entity_level` lookup
+  label instead of the ontology class. After `make seed`, walking
+  from Ada West shows "Demo Corp (Company)" -- not "Demo Corp
+  (Organization)". The payload now carries `entity_level_label`
+  from `common_lookup_value`. Missing lookups fall back to the
+  code. The same caption is the button accessible name.
+
+## [0.72.0] - 2026-08-16
+
+### Changed
+
+- Related-node person chips use the `person_side` lookup label instead
+  of the ontology class. After `make seed`, walking from Ada West
+  shows "Priya Nair (Counterparty)" and walking from Demo Corp shows
+  "Ada West (Our side)" -- not "Ada West (Person)". The payload
+  already had `person_side_code`; it now also carries
+  `person_side_label` from `common_lookup_value`. The same caption is
+  the button accessible name.
