chat: one-tap message copy under every settled message - #388
Merged
Conversation
A quiet copy control under every settled user and assistant message copies the message's prose — text blocks joined by blank lines, never tool output, thinking, or question chrome. Plain tap target only: it never intercepts press/hold, so native long-press selection stays fully available. Always visible on touch devices, hover/focus-revealed on fine pointers, with a brief Copied acknowledgement. Placement matches the existing code-block copy button: every copy affordance shares the lower-right corner (assistant rows opt out of their column's flex-start via align-self), a contract pinned in messageCopyButton.test.js.

Adds a small copy control under every settled chat message — user and assistant — so grabbing a whole answer (or your own note) is one tap, especially on phones where long-press selection across a full message is fiddly.
What it does
What it deliberately doesn't do
It is a plain tap target: no press/hold or context-menu interception, so native long-press selection and its action menu stay fully available (the existing chatUiPolish contract).
Placement
Every copy affordance shares the lower-right corner: code blocks already pin
right: 7px/bottom: 7px(from the earlier code-block copy button work, #272), user bubbles inherit their column'sflex-end, and assistant rows opt out of their column'sflex-startwith onealign-selfrule. Ghost button — always visible on touch devices, hover/focus-revealed on fine pointers, accent focus ring for keyboard users.Tests
messageCopyButton.test.jscovers the copy-text semantics (prose only, augmentation stripping, empty system rows), the plain-tap-target contract, the settled-only gate, and the shared lower-right corner.🤖 Generated with Claude Code
