- On a gallery booth the marks panel moves into a sticky verdict aside beside the set. The aside comes first in the document, so a narrow screen stacks the question above the work; grid areas place it on the right when wide. Nothing in an ordered collection moves. Boards are unchanged. - The flag tray lists flagged items by tile number: the declared change from the panel list's (created, id). The standalone marks page keeps the list. - Inline group headers are divs, never figure.item. - Every mark-dependent element is a data-region: the verdict, each tile, the rail's filter counts. There is also a server-rendered status line. - The in-place script (base.html) POSTs with an explicit JSON Accept, then on 204 swaps every region from a fresh GET. Live media and per-viewer view state are carried across the swap, so there is no layout jolt and no stopped track. It never re-POSTs: on failure it says so and reloads. Tile controls re-bind after a swap, and the grid cursor survives it. - The `n` key opens the tile's closed note disclosure before focusing it. - test_embed_browser's keyboard-flag test expected a navigation, which is the defect R2 removes. It is updated as declared in the contract, and tightened: a window marker must survive, proving no reload. Browser tests: flag in place, with no reload and no scroll jump, and the tile, tray and rail count all updated; and a failed save that reloads without re-POSTing. Two mutations turn them red (no carry, no rail region). 700 passed.

"""U3 — the declared embed seam, in a real DOM.
|
|
|
|
The Python suite can prove what the server OFFERS. It cannot prove where a
|
|
fragment lands, whether the author's own markup survived the mount, or whether
|
|
four radio groups scattered down a report still submit as one POST — and that
|
|
last one is the operator's most important workflow. Before U3 those properties
|
|
were true by construction, because the server did the placing and the `form=`
|
|
bindings were static by the time the page was parsed. Now they are true because
|
|
`/_booth/embed.js` does it in a live document, which is a different kind of
|
|
claim and needs a different kind of test.
|
|
|
|
So: a real uvicorn on an ephemeral port, a real Chromium.
|
|
|
|
SKIPS, NEVER FAILS, when playwright or the shared browser is unavailable. The
|
|
box-wide store at /opt/ms-playwright pins specific Chromium revisions and a
|
|
playwright release that wants a newer one dies with an opaque "Executable
|
|
doesn't exist" — see pyproject's version bound. A test layer that goes red for
|
|
an environment reason teaches nothing and trains people to ignore it.
