Let's please move the typing for things to where they originate. Ex: If this is a Name and not an arbitrary string, then we should apply that typing here.

Please apply this idea everywhere it is relevant.

Note how the reinterpretation of this value as a Name is happening several lines below. I don't like that.

Alright, I've changed this to const nameFromQuery = searchParams.get("name") as Name | null which is really the only other option here as far as I can tell.


const name = nameParam ? (decodeURIComponent(nameParam) as Name) : null;
const name = nameParam ? (nameParam as Name) : null;

const { data: namespace } = useNamespace();

const ensAppProfileUrl = name && namespace ? getEnsManagerNameDetailsUrl(name, namespace) : null;
const ensAppProfileUrl =
name && isNormalizedName(name) && namespace
? getEnsManagerNameDetailsUrl(name, namespace)

Any special reason not to move the isNormalizedName check into the implementation of getEnsManagerNameDetailsUrl?

Please ignore if not relevant.

getEnsManagerNameDetailsUrl lives in the namehash-ui package. isNormalizedName is the responsibility of the actions here. Maybe we should not link at all if it's not normalized.

I don't understand why you mention how getEnsManagerNameDetailsUrl lives in the namehash-ui package? How is that relevant to the ideas here?

If we say that we don't want to link to the ENS Manager Name Details page for unnormalized names, then that decision should move into getEnsManagerNameDetailsUrl so that we never need to talk about it again.

Otherwise we have to keep endlessly talking about the implementation details of unnormalized name handling which I really hate as I've been doing that over and over again for 4 years.

if (!ensAppProfileUrl) return null;

The original issue stated:

Refine typing of "downstream" name variables, ex: in ProfileHeader

and most recently:

As much as possible, we need to stop passing Name values around anywhere because they are a motherfucker of problems

We should never take raw name values and put them in UIs. All names appearing in UIs should go through the logic we define in the NameDisplay component.

🧹 Nitpick | 🔵 Trivial

Consider displaying the interpreted name in the error message.

Since InterpretedNameUnsupportedError is shown for valid InterpretedName values (with encoded labelhashes), you could accept a name: InterpretedName prop and display it using formatInterpretedNameForDisplay for better user context. This aligns with past review feedback suggesting <InterpretedNameUnsupportedError name={...} />.

💡 Optional enhancement 
+import type { InterpretedName } from "@ensnode/ensnode-sdk";
+import { formatInterpretedNameForDisplay } from "@/lib/format-interpreted-name-for-display";
 import { ErrorInfo } from "@/components/error-info";

-export function InterpretedNameUnsupportedError() {
+export function InterpretedNameUnsupportedError({ name }: { name: InterpretedName }) {
   return (
     <section className="p-6">
       <ErrorInfo
         title="Encoded Labelhash Detected"
-        description="The provided name contains encoded labelhashes. Support for resolving names with encoded labelhashes is in progress and coming soon."
+        description={`The name "${formatInterpretedNameForDisplay(name)}" contains encoded labelhashes. Support for resolving names with encoded labelhashes is in progress and coming soon.`}
       />

In `@apps/ensadmin/src/app/name/_components/NameErrors.tsx` around lines 11 - 20,
Update the InterpretedNameUnsupportedError component to accept a prop name of
type InterpretedName and show the interpreted name in the error description
using formatInterpretedNameForDisplay; specifically, change the
InterpretedNameUnsupportedError signature to take { name: InterpretedName },
call formatInterpretedNameForDisplay(name) and include that string in the
ErrorInfo description (or add a separate field) so the rendered message shows
the actual interpreted name for context.

This was changed because of the comments made about the downstream handling, and:

As much as possible, we need to stop passing Name values around anywhere because they are a motherfucker of problems

NameDetailPageContent only ever receives a validated normalized name from the detail page check (isNormalizedName(nameFromQuery)), so the prop type was tightened to reflect that guarantee
