description	Keep the three custom-domain surfaces in sync — profile domain settings, publication domain settings, and the leaflet share-menu domain picker. Use whenever you change how domains are listed, verified, assigned, unassigned, or deleted in any one of them, since each surface hand-rolls its own row UI over the same data and drifts silently.

Custom domain settings

A custom domain is one row of custom_domains, reachable from three places that each render their own row markup over the same identity data and the same useDomainStatus / DomainVerification pieces. Nothing is shared below the data layer, so a change to one surface leaves the other two looking and behaving differently, with no type error and nothing failing in CI.

The three surfaces

#	Surface	Entry point	Rows
1	Profile domain settings (/settings?tab=domains)	app/(app)/(identity)/(home-pages)/(writer)/settings/domains/DomainTab.tsx	PublicationDomain.tsx, LeafletDomain.tsx, UnassignedDomain.tsx
2	Publication domain settings (dashboard → settings)	app/(app)/(identity)/lish/[did]/[publication]/dashboard/settings/PubDomainSettings.tsx	PubDomainRow (current/default + alternates), UnassignedDomainRow (available)
3	Leaflet share menu → custom domain	app/(app)/(editor)/[leaflet_id]/actions/ShareOptions/DomainOptions.tsx	LinkedDomainOption, NonLinkedDomainRow, plus VerifyDomainView

Surface 1 is the only place a domain is added (AddDomainForm) or deleted (DeleteDomainButton). Surfaces 2 and 3 only assign/unassign an existing domain.

Surfaces 1 and 2 open verification through DomainVerificationModal, exported from settings/domains/DomainVerification.tsx — pass it domain and a trigger; it owns the modal title, width, and DomainVerification body. Don't re-wrap Modal + DomainVerification by hand in either place.

Surface 3 deliberately does not use that modal: it lives in the share popover and swaps the menu to its own VerifyDomainView via setDomainMenuState({ state: "domain-settings", domain }). Leave it that way unless asked. So an "open the verification UI" change is expressed twice — once as a DomainVerificationModal trigger, once as a menu-state transition.

What they share

• useDomainStatus(domain) (settings/domains/useDomainStatus.ts) — SWR on get_domain_status; pending is truthy while the domain is misconfigured or awaiting DNS verification. One hook call per row, so it must be called from the row component.
• useDomainStatuses(domains) (same file) — the list-level version, one SWR key for the whole list, used when a surface needs to bucket or order rows by verification state (surface 3 separates unverified rows from available ones with it). It seeds the per-domain domain-status-${domain} keys, so a row or view that later calls useDomainStatus reads from cache instead of refetching. Don't call useDomainStatus in a loop to get the same thing — the hook count has to stay stable as domains are added and deleted.
• DomainVerification (settings/domains/DomainVerification.tsx) — the DNS record table. Returns null when not pending. Never make a row that opens it unconditionally, or a verified domain opens an empty modal/view.
• DomainVerificationModal (same file) — the modal wrapper around it, used by surfaces 1 and 2 (see above).
• getDomainAssignment / describeAssignment (settings/domains/domainAssignment.ts) — classifies a domain as publication / document / unassigned. Surface 1 buckets its sections with it; surface 2 uses it for the reassign confirmation. Surface 3 filters by hand (publication_domains.length === 0, then route match on permission_token.id) instead of using it — so a change to what counts as "assigned" needs applying there too.
• Server actions in actions/domains/index.ts: addDomain, assignDomainToDocument, assignDomainToPublication, removeDomainAssignment, removeDomainRoute, deleteDomain.
• Data source: identity.custom_domains via useIdentityData (surfaces 1, 2, 3) plus publication_domains from usePublicationData (surface 2) and useLeafletDomains (surface 3). Optimistic updates go through mutateIdentityData(mutateIdentity, draft => …); after a write, mutate cache the surface reads, or the row snaps back.

Current conventions (keep these consistent across all three)

• An unverified domain row: the domain name pulses (animate-pulse) and is font-normal (verified domains are the bold ones); the affordance reads Verify in text-accent-contrast font-bold — not "pending", not "unverified", not a spinner, and the label itself doesn't pulse.
• The whole row is the trigger: a single <button type="button"> wrapping name + label, passed to Modal with asChild (surfaces 1, 2) or wired to the menu-state transition (surface 3). Per project convention, a button used as a Modal/Popover trigger always gets asChild.
• A row that also holds its own control (surface 1's DeleteDomainButton) keeps that control outside the trigger button — don't nest buttons, and don't rely on stopPropagation to untangle two nested triggers.
• Verified-but-unassigned rows are not clickable-to-verify; they show the assign affordance (surface 2's assign, surface 3's route input) or plain text (surface 1).
• Grouping unverified rows above the rest, separated by an hr, is surface 3 only by decision. Surfaces 1 and 2 leave unverified rows interleaved in list order.

Required step: ask about the other two

Any change to domain row UI or behavior in one surface is a three-surface change until the user says otherwise. After making the change, use AskUserQuestion to ask whether the same change should be applied to the other two surfaces — name them specifically (e.g. "also apply to the leaflet share menu picker and the publication dashboard rows?") and say what the equivalent would be in each, since the mechanics differ (modal vs. menu-state, assign vs. publish-to-route). Don't silently do all three, and don't silently do only one.

This applies to: label text, pending/verified states, colors, pulse/animation, what part of the row is clickable, where verification opens, assign/unassign affordances, empty states, and the copy in each.

Verify before calling it done

npx tsc. Then, for each surface you touched:

1. An unverified domain — name pulses, Verify reads as clickable, clicking anywhere on the row opens the DNS record table for that domain.
2. A verified domain — no Verify, no pulse, and the assign/publish affordance works.
3. Surface 1's delete icon still opens the delete confirmation and doesn't also open verification.
4. Surface 3 inside the share popover — the row click swaps to VerifyDomainView and the back arrow returns to the picker (rows there use onMouseDown, which the popover needs; don't switch it to onClick without checking the popover doesn't eat it).
