- Update test: parseSummary with <observation> tags now returns salvaged
summary object instead of null, matching the intentional #1908 behavior
- Fix docstring: salvageSummaryFromObservationTags extracts from all
observations, not just the first
- Add explanatory comment in test linking #1360 → #1908 behavior change
