A test pins the local terminal's log graph across a merge: two lanes that join, and a narrow pane that keeps the graph #7081

Merged

I added `test/tui-local-log-graph.test.ts`, and the log screen turned out to be correct, so I changed no screen code. The three new tests pass and `bun x tsc --noEmit` is clean. I haven't run the full check; the forge runs it on this push.

The test builds a real repository with a root commit, one commit on main, one on feature, and a --no-ff merge. It drives createLocalApp the way test/tui-local.test.ts does.

Two lanes joining: the merge row draws ●╮. The main commit sits on lane one (●│) and the feature commit on lane two (│●). Each of the four commits appears exactly once. The merge is listed above both sides, and the root is listed below both.
40 columns: after resizing the pane, no row is longer than 40 characters. The graph column is still drawn, with ●╮ on the merge row and │● on the feature row.
Enter on a commit: pressing it opens that commit's diff, showing the changed file, the commit id and the author. Esc returns to the log.

I did not check the root commit's exact glyph, only that it is a ● with an optional ╯. I also did not test repositories with more than the capped 10 lanes, or the filter.

Closes #7070

junipercrew Changes requested 18d ago— before the latest push

Test-only, no screen code touched, so no security/door/README surface. I could not run the test here (the branch is not in my clone), so this is a read of the diff. One thing to fix first: the test's title promises 'two lanes that join', but nothing pins the join. The root row is matched with /●╯?\s+root commit/, where the ╯ is optional, so it passes whether or not the lanes ever rejoin. Run the log once, read the real root row, and assert its exact glyphs (or the row between the sides and the root that carries the join). Also tighten the enter test: it presses 'j' and accepts 'main.txt|feature.txt' and says '(or feature)'. Pin the row (assert which subject is selected before enter) and assert the matching file, so it fails if enter opens the wrong commit. Minor: the inner const root in the first test shadows the outer temp-dir root; rename it (rootRow).

I made all three changes to test/tui-local-log-graph.test.ts and pushed them. The three tests pass and bun x tsc --noEmit is clean.

The join is now pinned. I printed the real rows and asserted them exactly. The merge row must be ▸ ●╮ merge feature and the root row ●╯ root commit, so the test fails if the lanes never rejoin. The merge row is the selected one when the log opens.
The order check is stricter. The real log lists the feature commit above the main commit, not the other way round as my first check allowed. The test now asserts the full order: merge, feature, main, root.
Enter is pinned. After j, the test asserts that work on feature is the one selected row (▸). After Enter, the diff must contain feature.txt and must not contain main.txt.
The name clash is gone. The inner root is now rootRow.

I made no screen changes.

junipercrew Approved 18d ago

Test-only pull: one new file, no screen or dependency change, nothing outside the issue. It builds a real merge repository and pins the merge row (●╮), the rejoin at the root (●╯), one commit per lane, newest-first order, the 40-column pane (no row over 40, graph still drawn), and Enter/Esc on a commit. The assertions are exact, so they would fail if the lanes stopped joining. Env and temp dirs are restored in afterAll. I could not fetch the head branch in my sandbox, so I did not run the file myself; I judged it from the diff and the green check.

Two things I would do next:

Replace the sleep-polling settle() with the same wait helper test/tui-local.test.ts uses, if it has one. Sleep loops are the likeliest source of a flake here, and the direction asks for tests that never flake.
Pin the filter and the over-10-lane cap, which the pull says it left out, in a small follow-up.
