fix(gui): reserve the sidecar hint in lines so the pair stays aligned - #2905
Conversation
The dashboard's two sidecar cards are a matched pair whose control rows must
start at the same y. In Russian and French they were 19.5px apart at every
two-up width (1600 down to 740). English, Korean, Japanese, Chinese, German and
Turkish measured clean, which is why this survived.
Both cards wrap their control group onto a second flex line, and that line
follows its own card's copy height, so the copy row has to be equal in both
cards. It was equalised by `min-height: 3.9375rem` on the copy block — 63px,
derived in the comment as "21px title + 3px hint margin + two 19.5px hint lines".
That is a pixel count carrying a two-line assumption and a hard-coded
line-height. At ru/fr the vision hint takes a THIRD line at a two-up card
(82.5px of copy against 63px), the band no longer describes the taller card, and
the pair drifts by exactly one line.
The floor now sits on the hint and is expressed in `lh`:
.dash-sidecar-row-card .dash-sidecar-copy .setting-hint { min-height: 3lh; }
Three line boxes is the longest shipped hint at the narrowest two-up card, so the
shorter hint reserves the same three lines and both control rows start together.
Being in `lh` rather than `rem` means a font or line-height change cannot
invalidate it, and a longer translation only matters if it exceeds three lines.
Measured on the rendered page with a CDP harness that overrides the viewport:
worst paired offset 0.0px (was 19.5px) across all eight shipped locales at 1024
and 1100, and across 1600/1440/1280/1010/760/740 for ru and fr. No hint is
truncated, no card collapses, and the one-column horizontal row layout is
unchanged.
Two notes for whoever touches this next, both learned the hard way here:
- Shared row tracks (`grid-template-rows: subgrid`) are the textbook fix and do
not work on this surface. The cards sit under container-query containers, and
layout containment makes Chrome reject a child's `subgrid` outright: the
computed value came back `none`, rows collapsed to a single 19px line box, and
cards rendered 54px tall with controls overflowing up to 80px past the panel.
- That collapse still reported a 0.0px alignment delta, because both cards were
broken identically. A relative metric cannot see a symmetric failure, so the
harness now also asserts absolute card height, child overflow, and hint
truncation. It additionally refuses to trust any measurement taken while a
probe stylesheet is still injected — an earlier "all clear" in this work was
exactly that, and it hid this defect for several rounds.
`tests/sidecar-layout.test.ts` asserts the line-based floor and that the pixel
band is gone, and was driven red against the previous CSS (2 fail) before passing
on this one (8 pass).

This says align-content: start is absent from the shipped diff, but this same commit adds it to gui/src/styles-dashboard-workspace.css and adds a regression assertion requiring it in gui/tests/sidecar-layout.test.ts. Since the preceding 012 record also describes the declaration as necessary once the copy heights are equalized, the final audit record leaves future maintainers unable to tell whether it is load-bearing or an accidental experiment; revise this conclusion to document the combined fix, or reconcile the CSS and test with the stated conclusion.

Reviewed exact head dc78ceb. The focused sidecar layout test passes 8/8 with isolated HOME paths, and the CSS direction itself is sound. I am requesting changes because the committed review record is not consistent with the code that would land.
- devlog/_plan/260829_gui_dashboard_slop/012_shipped_fix_and_subgrid_postmortem.md and 013_final_shipped_and_measurement_lessons.md still describe the old 3.9375rem band and claim align-content: start was not shipped, while this exact head removes that band and requires both align-content: start and the 3lh hint floor. Update both records to describe the actual combined fix.
- The unrelated future-track notes 020 and 030 should either move to the stacked child PR that implements them or be made explicitly non-shipped and lint-clean. At this head, 020 has an untyped code fence, and git diff --check also reports trailing blank lines in all seven newly added devlog files.
Please keep the clean two-file GUI fix and its relevant audit record, make the documentation truthful at this exact head, and rerun the focused GUI gate. I am not requesting any broader GUI or copy change.
Codex and CodeRabbit both flagged the same contradiction: 013 said `align-content: start` was not in the shipped diff, while the same commit ships it and the regression test asserts it. The reviewers were right, and the doc was wrong in a way that would have let a future maintainer delete a load-bearing line. Settled it by removal test rather than by rewording. With the shipped stylesheet live, neutralising one declaration at a time and re-measuring the rendered page: both shipped worst paired offset 0.0px 3lh only (align-content: stretch) 27.8px align-content only (old rem band) 19.5px Both ship, and each fixes a different half: `align-content: start` controls how the wrapped flex LINES distribute, `min-height: 3lh` controls the height of the copy row those lines pack against. Neither alone closes the defect. - 013: shipped block now lists both, with the removal-test table; the measurement-lessons section now corrects the *sufficiency* claim about `align-content` instead of denying that it shipped. - 012: marked superseded where it concludes the `3.9375rem` band is load-bearing — the band is not in the shipped stylesheet; a copy-row floor is, and it is `3lh` on the hint. - 030: described a `100dvw` toast cap that was deliberately reverted. Now records what shipped (the `.action-toast.notice` specificity fix, and why the containing-block rewrite was dropped as unreproducible). - MD040: tagged the three untagged fences (`css` in 020, `text` for the two DOM trees in 010). No stylesheet change: the CSS was already correct, only its record was not. gui/tests/sidecar-layout.test.ts still 8 pass / 0 fail.
|
Rechecked exact head 1a7f22f. The two postmortems now correctly record both load-bearing declarations, 020 is explicitly withdrawn, and 030 clearly separates the reproduced specificity fix from the unshipped viewport-width rewrite. That resolves the substantive documentation blocker. One mechanical cleanup remains before I can clear the changes request: git diff --check still reports new blank lines at EOF in devlog/_plan/260829_gui_dashboard_slop/000_baseline_and_roadmap.md:124 and 011_audit_correction_align_content.md:115. The other five files are clean now. Remove those two final blank lines; the focused GUI test was already green on the unchanged CSS. |

The hygiene gate flagged `missing_regression_test`: this branch changes `gui/src/styles.css` with no test change, and the reviewer asked for the same treatment #2905 gave the sidecar rules rather than a test exception. Two source-text assertions, matching the existing `gui/tests` convention for CSS contracts (happy-dom performs no layout, so a computed value here would prove nothing; the rendered proof was taken in a real browser via CDP). - `.logs-table-wrap` must cap against `100dvh` and must not go back to static `100vh`. Static `vh` resolves against the large viewport, which is what put the last log rows under mobile browser chrome. - The toast cap must stay on the two-class `.action-toast.notice` selector, and both halves of `min(480px, calc(100vw - 48px))` must survive. A single-class `.action-toast` cap silently loses to `.notice { max-width: var(--prose-measure) }` — equal specificity, declared later — and dropping the viewport term let the toast reach the screen edge at 430px. The second test also guards its own premise: it asserts `.notice` still appears after the compound rule, because the whole reason the compound selector is needed is that source order. If `.notice` ever moves above it, the test fails rather than quietly permitting a "simplification" back to one class. Driven red first: against the parent commit's stylesheet both tests fail (the `dvh` assertion, and `.action-toast.notice` not existing at all), and both pass on this branch's.

The unit's roadmap described the work in the future tense and recorded no landing, so a reader arriving at 000 could not tell that all three PRs had merged, nor which of the three reported defects turned out not to be one. Adds a terminal Outcome section: the three merged PRs with their commits (#2905 fc74e20, #2906 4d646c4, #2911 e1becb7), what each shipped, and one paragraph per work phase recording the finding that mattered. The parts worth finding later: - Both sidecar declarations are load-bearing, each confirmed by removal: 3lh alone leaves 27.8px, align-content: start alone leaves 19.5px, together 0.0px. They fix different halves - line distribution and copy-row height. - Subgrid is unavailable on this surface at all, because container-type ancestors make Chrome reject a child's grid-template-rows: subgrid. - wp2 was withdrawn on measurement, not implemented, and says so. - The toast defect was a cascade problem rather than a unit problem. - Two measurement traps that each produced a confident wrong answer here: a symmetric break passes a relative alignment gate, and a leftover injected probe stylesheet describes a page that is not the shipped page. Documentation only; no stylesheet or test is touched.

Summary
The dashboard's two sidecar cards are a matched pair whose control rows must start at the same y. In Russian and French they were 19.5px apart — exactly one line box — at every two-up width from 1600px down to 740px. Six other locales measured 0px, which is why this survived.
The fix is two declarations, and both are load-bearing:
They close two independent halves of the same symptom.
1. The wrapped lines were mis-distributed. Both cards wrap their control group onto a second flex line. The grid stretches both cards to the taller one's height and
align-contentdefaults tostretchfor a multi-line flex container, so each card spread its own leftover space across its own lines. The two cards' content heights differ — the vision card's control group carries the advanced disclosure — so the card with more slack pushed its control line down.align-content: startpacks both cards' lines from the top. It isalign-contentrather thanalign-itemsbecause the mis-distributed thing is the lines;align-items: centerstays inherited and keeps the single-line (one-column) regime centred, wherealign-contentis inert.2. The copy row those lines pack against was unequal. It had been equalised by
min-height: 3.9375remon the copy block — 63px, documented as "21px title + 3px hint margin + two 19.5px hint lines". That encodes a two-line assumption and a hard-coded line-height. The ru/fr vision hint wraps to a third line at a two-up card (82.5px of copy against 63px), so the band stopped describing the taller card. The floor moves to the hint and is expressed inlh: three line boxes is the longest shipped hint at the narrowest two-up card, so the shorter hint reserves the same three lines. Inlhrather thanrem, a font or line-height change cannot invalidate it.Each declaration proven necessary by removal

Why not subgrid
Shared row tracks are the textbook fix and were tried first. They cannot work on this surface: the cards sit under container-query containers (
.dash-sidecar-gridand the per-cardsidecar-cardthe narrow-card queries depend on), and layout containment makes Chrome reject a child'sgrid-template-rows: subgridoutright. The computed value came backnone, tracks collapsed to a single 19px line box, and cards rendered 54px tall with controls overflowing up to 80px past the panel. An isolated clone with no container ancestor worked perfectly, which is what identified containment as the cause.That collapse still reported a 0.0px alignment delta, because both cards were broken identically — a relative metric cannot see a symmetric failure. Worth knowing before trusting an alignment number on this component.
Verification
Measured on the rendered page with a CDP harness that overrides the viewport (
Emulation.setDeviceMetricsOverride) and reads livegetBoundingClientRectvalues, asserting alignment and absolute card height, child-vs-panel overflow, and hint truncation. The harness also strips injected probe stylesheets before measuring and fails if any remain, after a leftover probe sheet once produced a false "all clear".gui/tests/sidecar-layout.test.tsasserts the line-based floor, that the pixel band is gone, and thatalign-content: startis present on the shared card class and absent from either card individually.
