nwhitehouse makes attachment chips actually open the document

Those little file tags on chat messages used to be pure decoration - now they're a one-click route to the document itself.

chat-uiworkflow

When a user attaches a document to a message in Mike's assistant chat, that attachment shows up as a small tag on the message. Until now, clicking it did nothing. nwhitehouse wired those tags up so a click opens the underlying document, and made sure the fix lands in both places the chat appears - the standalone assistant and the project-level assistant - so the behaviour is consistent wherever you're working.

The handling is sensibly conservative: tags that point to a stored document become clickable and resolve to the current version when you open them, while tags for attachments that never went through document storage stay as plain, non-interactive labels. No half-broken buttons.

So what Anyone whose team works documents through Mike's chat gets a faster path from "the assistant mentioned this file" to actually reading it.

`e67b072f`	[bug] Make user-message attachment chips clickable to open the doc	Nick Whitehouse	2026-05-06	↗ GitHub
commit body The chip in the user bubble (e.g. "sek-1300000000-eur-..." next to a prompt) showed the filename but had no affordance - clicking did nothing. Now renders as a button when document_id is present and an onOpenDocument handler is wired, opening the doc in the side-panel viewer (same path as the assistant's "Read <filename>" block uses). versionId is left null at the chip level - DocView resolves to the document's current version.

`4f480f20`	[bug] Wire chip-click on the project chat page too	Nick Whitehouse	2026-05-06	↗ GitHub
commit body UserMessage is rendered from two routes - /assistant via ChatView and /projects/[id]/assistant/chat/[chatId] directly. The previous chip-click commit only wired ChatView; in-project chats were the common case and showed no effect. Both surfaces now pass onOpenDocument so the attachment chip opens the doc viewer regardless of route. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
