CLAUDE.md's shell prose said the phone's header "controls shrink or
stand down"; there is no header there now. The search box's section
gains the modal and the four rules behind it, page-header gains the
count as the last thing to yield, and the top-bar-fit section gains
what happens below its own band.
NOTES.md gets the three measured facts, dated: `contain: paint` is why
a Web Awesome popup is clipped on Chrome 113 and why no tier here can
reproduce it, the arithmetic that cost the page header its count at
320px, and the shared long-lived e2e app that makes an absolute
coordinate a hidden assertion about background jobs.
The row is deleted from the grid template below 600px, not the header
hidden. That is 3.25em of a 439 CSS px viewport -- the single biggest
vertical win the reference device has to give, and the reason the issue
asks for the row rather than for a smaller bar.
Each of the five things the bar held has somewhere else to be there:
nav-history is the platform's own back gesture and was already gone from
899 down, the job indicator is <job-band> (#62, which is what this was
blocked on), the search box is a modal opened from the view's own
header, the library filter is Settings -> Libraries, and the wordmark
stays where it is.
Three things are load-bearing.
**The header is visually hidden rather than display: none**, because
that h1 is the document's top-level heading and several pages have no
other one -- page-header renders no h1 when its heading is empty, and
Settings has no page-header at all. Its four controls are display: none
*inside* it, which is what keeps them out of the tab order: a
visually-hidden container is still focusable, and tabbing into a search
box nobody can see is worse than not having one.
**The fit pass stands down**, from the bar's computed position rather
than from a width. With the bar out of flow there is no content box to
measure children against, and a pass that ran would collapse the
wordmark on every resize and report success about a 1px box.
**top-bar-fit.spec.ts keeps 390 and asserts the stronger property.**
"Nothing hangs out of the bar" is trivially true of a bar with no row
and would pass on a build that merely broke it, so what that width asks
now is that the content starts where the row above it ends. Measuring
against the window instead would have been asserting "and no background
job is running", which that spec is not about and cannot arrange.
Closes#57
library-filter is the only control in the app that calls
setSelectedLibrary, and the phone already hid it with a comment saying
it was "reachable from the drawer's Settings". It was not: Settings adds,
removes, renames and scans libraries, and does not set the view filter,
which is a different thing -- it decides what Albums, Artists and Genres
show. A phone therefore inherited whatever a desktop session last chose
and could neither change nor see it, which is #24's sentence broken in
the band it was written for.
It is a second *placement* of the same component, not a second control,
and it is at every width rather than below 600px. A phone-only copy is
the cheaper answer and is the fault rather than the fix: "where do I
change which library I am browsing" having two answers by viewport is
exactly what one control in two places avoids.
Closes#148
Adding the phone's search button to this header is 43px more than the
row has at 320px, which is a width the app promises and which
header-action-overflow.spec.ts asks about. Measured on Playlists there,
after the fit pass had already collapsed all three actions into "More
actions" and truncated the title to nothing: title 0, count 50, sort
143, search 40, More 38, five 12px gaps and 32px of gutters -- 363 in
320, with the More button ending 27px past the edge. That is an action
clipped, which is the exact defect this pass exists to prevent.
The count is what yields, last, because it is the only item on that row
that is neither an identity nor an action. The title yields first and
may ellipsis away entirely, since the navigation also says which page
you are on; the sort control and the buttons are each the only place
they are said. An empty page says it is empty in its empty state and a
full one is being looked at. With the count gone the header is 304 in
304, and the title comes back to 19px.
It is rendered and hidden with an attribute rather than returned as
`nothing`, for the reason the action buttons are: every pass starts
from all-visible and needs a node to un-hide, or the first 320px window
costs the count for the rest of the session.
The phone's top bar is about to go, and the search box is the one thing
in it that is an action rather than chrome. It becomes a button in the
row that already says which page you are on, opening a wa-dialog with
the real search box in it.
Three decisions worth the words.
**A wa-dialog, and that is a mechanism rather than a taste.** wa-popup
renders `<div popover="manual">` and feature-detects the Popover API,
falling back to `strategy: "fixed"` where there is none -- which is
Chrome 113, the reference device, since `popover` is Chrome 114. And
`position: fixed` escapes ancestor overflow but not `contain: paint`,
which `.main-panel` carries, so a popup-shaped search panel opened from
a view's header is structurally clipped on that device. `<dialog>` /
`showModal()` is Chrome 37 and uses the real top layer. No tier here can
see the difference -- CI's Chromium and WebKit both have the Popover
API -- so the component test asserts the *mechanism*, a native
`<dialog>` in the tree, rather than the symptom.
**An element, not a PageAction.** Two of the seven searchable views are
detail views with no page-header; they filter on the term and say so in
their own headers. Declaring search as an action would mean seven hosts
each writing it out, which is a second list of searchable views, and it
would put a phone mode for actions inside page-header, which that
component documents its refusal to grow. search-store's own map is the
condition, asked by one component placed three times.
**The modal carries the real search-bar**, so there is still one
debounce, one clear button and one view-scoped placeholder. Escape
closes it and *keeps* the term -- the input treats Escape as "clear the
search", which is right in a header where the box stays on screen and
wrong in a surface whose dismissal would then discard the search.
