+Public-safe synthetic data: 79 recorded events and one separate single-record
+Goal, served by the packaged Chat frontend and disposable production history
+backend. These are presentation and recovery checks, not scientific results or
+installed-App adoption.
+
+- Before: `cd819fd206cd9de46a789df0669e13bb2ed763e5`.
+- List views use the same long, mixed-language records before and after.
+- Record views retain the same negative observation and its three revisions.
+- Source identities remain readable on demand; the Chinese view retains original
+  evidence text in its original language.
+- Comparison views preserve unmeasured versus measured zero and both originals.
+- `first-desktop.png` shows the complete first viewport before opening search.
+
+The PR description records the tested candidate revision and validation. The
+existing `research-record-search` scenario recreates the captures and checks
+paging, filtered downloads, keyboard expansion, help, partial/failed reads,
+recovery and Goal isolation without research execution or source mutations.
