Subject: [PATCH] fix: system-authored comments display as 'You' instead of
 'Paperclip' (#6330)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Thinking Path

> - Paperclip orchestrates AI agents for zero-human companies
> - The issue chat thread renders comments from agents, users, and the
system itself
> - When Paperclip's internal recovery system posts a comment (e.g.,
stranded issue recovery), it creates a comment with `author_type:
"system"`, no agent ID, and no user ID
> - The UI function `authorNameForComment` falls back to `"You"` when
both author IDs are null
> - This PR returns `"Paperclip"` instead for system notices
> - The benefit: system comments are clearly attributed to Paperclip,
not the logged-in viewer

## What Changed

- `ui/src/lib/issue-chat-messages.ts`: In `authorNameForComment`, the
null-userId fallback now checks `options?.isSystemNotice` and returns
`"Paperclip"` instead of `"You"` for system-authored comments. One-line
change.

## Verification

- 82/82 existing tests pass (issue-chat-messages 20,
IssueChatThreadSystemNotice 11, IssueChatThread 51)
- Manual repro: view any issue with a system-authored comment (stranded
issue recovery moves issue to blocked). Before: author "You". After:
author "Paperclip".

## Risks

Low risk. One-line change. Only affects system-authored comments with no
user/agent ID. The `isSystemNotice` flag is already computed upstream
(`comment.authorType === "system"`) and passed into this function.

## Model Used

zai/glm-5.1 (200K context). Investigation and code tracing assisted by
the model.

## Checklist

- [x] Thinking path included
- [x] Model specified
- [x] Checked ROADMAP.md — bug fix, not a feature
- [x] Tests pass locally (82/82)
- [x] Risks documented
- [x] Will address all reviewer comments
