## The Problem

PR#81 put `PR#<number>` right after the branch name, inside the branch cell.
The copy button of the branch name then came after the pull request, so it looked as if it copied `PR#12`.
On a phone, the branch line of a card got wider still, and long branch names had even less room.

## Non-Goals

- No change to what is shown or when; only where.
- The Repositories page and the home cards keep the pull request beside the name: they have no copy button, and their line wraps.

## The Scenarios

### Feature: the pull request apart from the branch name

#### Scenario#82.01: The build tables have a PR column

So that the copy button stands next to the name it copies.

- **Given** the Latest, Branches or History view
- **Then** the table has a column `PR` right after `Branch`
  - **and** the branch cell holds the name and its copy button only
  - **and** a row without a pull request has an empty PR cell
- **When** the page is polled, **then** `werkator.js` renders the same column

##### Verified by

- [UiControllerTest](../../src/test/kotlin/de/hoennig/werkator/server/UiControllerTest.kt) — the PR column after the branch cell, the copy button in the branch cell, an empty cell without a pull request

#### Scenario#82.02: A phone card has a PR line, or none

So that a card stays as wide as the screen.

- **Given** a screen narrower than 680 px, where table rows become cards
- **Then** the pull request is a line of its own, labelled `PR`
- **And** a row without a pull request has no PR line

##### Verified by

- Checked by hand in a browser at 375 px: no horizontal scrolling, the empty cell is `display: none`.

#### Scenario#82.03: Current Builds and the build page show it apart as well

- **Given** a running build or a build page of a branch with an open pull request
- **Then** the pull request stands apart from the branch: its own item in the card header, its own `Pull request:` line on the build page

##### Verified by

- [UiControllerTest](../../src/test/kotlin/de/hoennig/werkator/server/UiControllerTest.kt) — every page naming a branch still links its pull request

## The Solution

`builds.html` and `renderBuildRow` in `werkator.js` get a `PR` cell after the branch cell, with the class `is-empty` when there is no pull request.
The small-screen stylesheet hides `td.pull-request-cell.is-empty`, so an empty cell is no card line.
The Current Builds card puts the link into the header next to the branch span, and the build page gets its own fact line.

## Additional Changes

- The architecture skill says where the pull request is shown.
- Version 1.23.1 with its release note.
