The form split tags with the shared ParseList and attached the result verbatim,
so "team-a, TEAM-A" persisted as two entries and the constraints column read
dashboard_tags=[team-a, TEAM-A] — one grant reported as two on the page whose
job is to show what a key was granted. Enforcement never saw it (a session holds
its tags in a case-insensitive set), which is exactly why the display was the
only place it could surface.
De-duplicates ordinal-ignore-case at the attach point only, first spelling
winning, matching ApiKeyAdminCommandLineParser.ParseDashboardTags. ParseList is
untouched: the five glob lists are matched literally, so near-duplicates there
are not necessarily the same rule and must survive verbatim — pinned by a test.
The help text claimed to mirror the CLI flag; it now claims only the shared
separators and the dedupe, since the form still drops an empty segment silently
where the CLI hard-fails. A browser form has no exit code to fail with, so that
difference stays, and Authorization.md now records it.
