# Open and copy a shared Ideas List

A shared Ideas List link opens a preview of another person's list. Accepting it creates a recipient-owned copy; it does not join both people into one live collaborative document.

## Review the preview

1. Open the shared link.
2. Confirm who shared it and the displayed Ideas List name.
3. Review the visible cards and any provenance or sharing explanation.
4. Read the connection consequence for the selected share type before continuing.

Do not claim that opening the preview has already copied the list or connected accounts.

## Sign in when required

Domino can require authentication before copying the list or applying a card-specific intent.

1. Continue to the offered sign-in or registration flow.
2. Complete verification without sharing the code or magic link with an assistant.
3. Return to the same shared-list preview.
4. Confirm the pending copy action resumes for this share, not a different link.

If the user lands on an ordinary Ideas page without the expected copy, reopen the original link after signing in.

## Copy the list

Choose the primary action that opens or copies the shared Ideas List. Domino can prepare the personalized copy and resolve shared cards before the final result appears.

After completion, confirm:

- the new list appears in the recipient's own **Ideas** list selector;
- edits to that copy do not change the sender's original;
- the displayed provenance identifies where it came from;
- any connection behavior matches the original share type.

## Start from one shared card

The recipient can sometimes begin from a specific card rather than only copying the full list. Domino should preserve the intended card through sign-in and then finalize the action against the current shared-list state.

If the card cannot be resolved, do not substitute a similarly named place without telling the user.

## Connection behavior by share type

### Just one friend

Copying can connect the recipient with the sender. The completed connection state, not the mere link opening, is authoritative.

### A few friends

Copying can connect the recipient with the sender. If **Connect within this group (mutual, in-app only)** was enabled, Domino can offer or apply the supported mutual group behavior. Do not imply that every group member sees every other member's private activity.

### A wider circle

Copying does not create connections.

## Likes and privacy

The copied Ideas List belongs to the recipient. Its general edits and refinements do not rewrite the sender's list.

Likes remain private, but the original sharer or relevant shared group may be able to see that the recipient liked an item within the supported shared-list relationship. Do not broaden this into a claim that the sender can see every list edit, search, or filter.

## Reopening, duplicates, and invalid links

- If the list was already copied, Domino can route the user to an existing copy or prevent an unintended duplicate.
- If the link is invalid, expired, or unavailable, ask the sender for a new share link.
- If the recipient used the wrong account, sign out only if the user explicitly wants to switch identities, then reopen the original link.
- If a shared card is still being resolved, wait for the preview rather than repeatedly copying.

## What the sender can safely be told

Creating a link proves only that the link exists. Copying can establish a recipient-owned list and supported relationship state, but it does not prove the sender delivered the link through Messages or email.

## LLM answering guidance

- Separate preview, authentication, copy preparation, completed copy, and connection state.
- Always explain that the recipient gets their own copy.
- State the share-type connection consequence before the user accepts it.
- Never expose a private copied list or recipient like beyond the current authorized viewer.
