 The status line offers the keys for the tab and for the list or the details. When the whole hint doesn't fit, it shows a shorter one, down to `Esc close` or `Esc leave` alone, so Esc shows at 80 columns beside the sidebar and at 40 columns without it. The keys follow how the same frame draws the details, so when a resize turns a pane into a dialog, the first frame already says Esc closes it. They also follow the links the same frame shows, so when T3 removes the link whose details show, the first frame without them offers the list's keys.
 
-Once T3 has answered with the pull request, a link's details have two tabs, `Summary` and `Timeline`, named on the row above them after `← List`. → or `l` shows the Timeline, ← or `h` goes back to the Summary and then to the list, and a click on a name shows that tab. Each keeps its own scroll. The Timeline is the desktop's Timeline tab: the pull request's opening, its commits, its remarks and its merge or close in one list, newest first. A header counts the comments, the commits and the approvals that still stand, as in `12 comments · 4 commits · 2 approvals`, and `Newest first` at its end switches the order. Each commit shows its headline, the lines it changes, its short id, its first author and when. Where the host gives a diff, Enter or a click on a commit shows its own diff on the Code tab. Where the host or T3 keeps which files you viewed, the Code tab counts them, as in `12 files · 2 / 12 viewed`, and marks each such file `✓ Viewed`, or `Changed since viewed` once someone pushed to it since. t3term can't mark a file yet. Each verdict is a row of its own, such as `✓ octocat approved`, grey with `, before the latest commits` when commits came after it, with its text under it. The other remarks between two such rows fold into one, such as `› 3 comments` with `2 authors · 6h ago` under it, which ↑, ↓ and Enter or a click open. [Linked pull requests](docs/pull-request-panel.md#the-timeline) compares each row with the desktop's.

 The links come from the thread T3 already sent: its `pullRequests`, or its one older `linkedPullRequest` when T3 sends no list. An empty list means every link was removed. Listing them asks T3 for nothing, and only opening a link's details reads its pull request. t3term runs no `gh`, reads no token, changes no link and starts or stops no watch. It hides the links the desktop hides, the `stack-dismissed` ones a reader unlinked from a stack, and shows each pull request once, by its host, repository and number. `Loading…` stands in while the thread is on its way and `Unavailable` once it won't come. An environment whose capabilities lack `threadPullRequests` reads `Linked pull requests unavailable`, as the desktop's panel does, and a thread with no links reads `No linked pull requests`.
