feat(chat): add AttachmentsPanel.Item.Name and .Size leaves - #3768
Conversation
The default attachments row is now fully recomposable from leaves: .Item.Name renders the truncating file-name line and .Item.Size the formatSize-formatted byte label (null when the file has no size). RFC 29 ledger updated: both symbols move to the exported list, the two deltas are badged shipped, and the roll-up table gains their rows. The generated API reference and framework-candidates manifest are regenerated for the new symbols.
📝 WalkthroughWalkthroughThis change adds ChangesAttachmentsPanel item leaves
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The new attachment leaves currently diverge from documented composition behavior, so custom rows may render with incorrect styling or fail to support the promised element substitution, while conflicting documentation may direct consumers to an unavailable helper. Merge should wait for these bounded contract and documentation issues to be aligned. Possibly related PRs

When a consumer supplies children to either new leaf, it remains in ...props, is spread onto the <p>, and is then overwritten by the explicit attachment name or formatted size. This silently prevents callers from replacing the default content despite both components accepting React.HTMLAttributes<HTMLParagraphElement> and the compound's established child-replacement convention. Destructure children and render children ?? <default> in both Item.Name and Item.Size.
Useful? React with 👍 / 👎.

Align the formatSize visibility with the public export status.
This page calls formatSize public, but docs/rfcs/29-chat-api-shape/README.md, Line 8, lists it under “Not exported today”. Remove “public” or export the helper from veryfront/chat and update the status block. Otherwise consumers can follow this page and import a symbol that the public surface does not provide.
Based on learnings: For RFC 29, the status block is authoritative for current public exports.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Use a Tailwind-aware merge for the consumer-wins class contract.
The shared cn helper at src/react/components/chat/theme.ts, Lines 126-128, returns clsx only. It concatenates conflicting utilities instead of resolving them. A caller-provided text-* class does not reliably override text-sm or text-[var(--faint)], despite the shared contract at Line 107. Use the repository’s Tailwind-aware merge path for both leaves and add a conflicting-class test.
Also applies to: 386-397

Resolve the asChild contract mismatch before shipping.
AttachmentsPanel.Item.Name and AttachmentsPanel.Item.Size always render <p> and do not accept or consume asChild. The RFC states that every part accepts asChild and lists it for both leaves. Implement the shared Slot behavior with matching prop and ref types, or remove asChild from the shipped contract. Add focused tests for the selected behavior.

What
Adds two leaves to the
AttachmentsPanelcompound so the default file row is fully recomposable:AttachmentsPanel.Item.Name— one<p>with the file's name (truncating,"Attachment"fallback). Deliberately plain text: it does not reproduceAttachmentPill.Label's uploading shimmer; composeAttachmentPill.Labelfor that stateful treatment (noted in JSDoc).AttachmentsPanel.Item.Size— one<p>with the size formatted via the publicformatSizehelper; rendersnullwhen the file has no size. Always the faint secondary color; the error/destructive state line stays withAttachmentPill.Label(noted in JSDoc).Both are registered on the
AttachmentsPanel.Itemcompound and follow the shared leaf contract (classNamemerge,refthreading, native prop spread).Why
RFC 29 (#2975) proposes that every default anatomy be recomposable from addressable leaves. The attachments row's name and size lines were the remaining gap: composing a custom row forced either re-implementing the text lines by hand or pulling in
AttachmentPill.Label's combined column.Docs
