The shared-record strip was forced by capturing /api/auth/me and serving
it back with the sharing block filled. That state is now proved across
the payload validator, the fence store and the transition machine at
once, so a single route mock cannot produce it and the two narrow
repairs both stop one step short of the shell.
So the spec stops faking it: its own login jar, a real switch into the
seeded whole-record READ grant, and a place on the list of files that
run in exactly one project, because a second project would drive the
same session row from two browsers. The viewport below md that project
used to cover is measured inside the desktop project instead, where the
shell picks its column layout from the same width-driven rules.
The offline, shared-record, demo and maintainership strips lived inside
the content column, so each one pushed the top bar down while the
sidebar's logo band stayed at the top of the window. Both bands read
SHELL_HEADER_BAND and are therefore the same height with the same
border, and the single line they draw across the top of the app still
came apart: measured on the French maintainership strip, the two borders
sat 66.5px apart at 768px and 61.0px apart at 1280px, and the full
three-banner stack put them 184.5px apart. After the hoist the step is
0.00px at every depth and both widths.
A banner is a statement about the whole window, not about the content
column, so it belongs above the row. The outer wrapper keeps the h-dvh
and the row below takes what the banners leave, which means the stack
comes out of the viewport budget instead of being added on top of it:
the document still does not scroll at any depth, and <main> stays the
one vertical scroller at both breakpoints.
The existing seam guard could not see this class. It asserts that both
bands carry the shared band tokens, which stayed true the whole time,
and the e2e spec beside it measures a shell with nothing above the
header. The new spec forces the banners on through the conditions the
components actually read — an unmaintained locale, a patched account
payload, a real offline context — and measures the same two borders at
four stack depths. Reverting the layout change turns it red on the first
banner with the measured offset in the message, while the older seam
spec stays green.
The maintainership strip gains a data-slot so the shell's chrome can be
enumerated from one attribute.
