When accessing an event details page via a custom conference domain, the event’s URL key is sufficient for finding the page i.e. the title is not necessary
e.g. https://icfp25.sigplan.org/details/icfp-2025-papers/28 will redirect to https://icfp25.sigplan.org/details/icfp-2025-papers/28/Type-Universes-as-Kripke-Worlds
The redirect also works if the event’s title in the URL is replaced with arbitrary text
e.g. https://icfp25.sigplan.org/details/icfp-2025-papers/28/foobar also redirects properly

However, when accessing the details page via the conf.researchr.org domain and just the URL key, this results in a 404
e.g. https://conf.researchr.org/details/icfp-splash-2025/icfp-2025-papers/28 causes a 404
while the redirect works if another path element is given
e.g. https://conf.researchr.org/details/icfp-splash-2025/icfp-2025-papers/28/foobar redirects properly
Other examples
https://conf.researchr.org/details/pldi-2025/pldi-2025-papers/99 fails but https://conf.researchr.org/details/pldi-2025/pldi-2025-papers/99/foobar works
https://conf.researchr.org/details/icfp-splash-2025/hatra-2025-papers/3 fails but https://conf.researchr.org/details/icfp-splash-2025/hatra-2025-papers/3/foobar works
