Not deferred and not blocked on the per-device ownership interface the last
commit described. Withdrawn, because the premise was wrong.
USB is the bus the peripherals arrive on. Nearly every machine has a port in
some form, down to a bad micro-B on a board with nothing else, and the ones
that have none are not made worse by the stack being there. That makes it
structurally the same kind of thing as PCI, and this plan has never proposed
evicting PCI.
The eviction rule already said so and was read too quickly: "anything
discovered at runtime ... goes out" is about the things USB discovers, not
about USB. The keyboard and the root disk that arrive over it are on the path
to a shell, and the stack that finds them is part of that path.
The obstacles recorded in the previous commit are real, but they are not the
reason. Even with a minimal in-kernel fallback written and a per-device
ownership interface designed, the good USB driver and the minimal one would be
the same driver -- and an eviction that leaves an identical copy behind has
moved nothing.
hybrid.md is now closed and leaves the register in docs/plan/1.0.md. What the
four mechanisms were built for next is the foreign driver host.

The failure this is against is not scope creep. It is abandonment by promotion:
a thing gets built to the point where it works, the next thing becomes more
interesting, and the first is left in a corner -- in the tree, not finished, not
deleted, and not in any list. Enough of those and the tree stops matching its
own documentation.
docs/plan/1.0.md now holds the register, and it is the only place anything
half-built is listed. Four sections, because the kinds are genuinely different:
built and connected to nothing (the text layer, a font from disk, socket
activation, wait_vblank); started and stopped part-way (foundations 2-5, hybrid
H2, Schcom v0, a released PCI device that nothing brings back); named in a "what
it does not do" and still true; and frozen -- scoped, unstarted, not to be
started. The rule is that nothing enters except by being finished or deleted,
and that adding a row requires closing one.
1.0.md already said "two things in flight, never three". It was right and it was
not being followed.
Then the corners themselves, because a register written over a tree full of them
is just a longer list:
- cmd/init is deleted. Nothing had execed /bin/init since initcode.S changed
to /bin/schinit; it was built and installed on every image as an unreachable
fallback, and an unreachable fallback rots rather than saves.
- projects/schwm/ and projects/schde/ are deleted. Both said "to be deleted"
in their own first paragraph, which proves only that a directory marked for
deletion is not deleted by being marked. README-only, no code lost, and the
arguments each made are moved into wayland.md where they are still true.
- projects/schcom/schcom and schcom-demo were tracked binaries. Untracked, and
.gitignore'd.
Three code comments and one document described a boot that has not happened
since 7d44eb7. cons_serial_only starts set, but kmain clears it on its first
lines now, so the splash does not survive the boot and the kernel log is on
screen from the start. That reversal was earned by a Chromebox with no serial
port freezing at boot showing nothing at all, and the comments still argued the
losing side of it.
The site:
- a download page. One ISO, what it has actually been run on -- one machine,
under test -- Ventoy and dd, what the first boot looks like step by step,
and the build if you would rather. The support table names one Chromebox
rather than listing hardware, because one Chromebox is the entire bare-metal
record and a list would be fiction.
- Assets/usb.svg, drawn to the same rule as the other marks: two tones,
geometry only, the accent spent in one place, and that place is the activity
light because it is the part that tells you something is happening.
- Download is in both navs and is the hero's primary action; a closing band
ends the front page on it.
- the uberblock-slots and drivers-outside-the-kernel figures are gone. Three
numbers left, including the fastfetch one, which stays because it is funny.
Two things caught by rendering the pages instead of assuming: .hero p was
beating .filemeta on specificity and the file line was coming out at body size,
and the dd command was one line long enough that the card clipped it at `conv=`
-- a destructive command that can scroll half of itself out of view is a good
way to take somebody's disk. It is two lines now.

Two additions to docs/Website.
**The reader.** docs.html renders the 29 documents in docs/ in the site's own
theme -- index down the left, table of contents down the right, and links
between documents rewritten so ../history/schfs.md navigates inside the
reader instead of downloading a file.
The parser is ~150 lines in docs.js, not a dependency: it handles exactly
what docs/ uses, and a Markdown library would outweigh every other asset here
combined. Everything is escaped before a tag is emitted, so the only HTML
that reaches the page is HTML docs.js wrote. Verified by rendering all 30
documents (302 KB of Markdown) with zero failures, no unrestored sentinels
and no runaway loops.
One caveat, stated in the page itself rather than hidden: browsers block
fetch() on file:// URLs, so this page needs a server. It says so, with the
command, and offers the raw file as a fallback. The rest of the site is
unaffected.
**The flag.** A Progress Pride flag in the top bar and a line in the footer,
on both pages, permanently. Support with an end date is marketing. It is
deliberately small and deliberately not a page of its own -- this is an
operating system, and the flag is a statement, not a subject.

index.html, style.css, app.js and the three marks. No build step, no
dependencies, no framework -- it opens from a file:// URL.
The palette is not a design decision: it is include/theme.h transcribed,
including the rule that header enforces. PSOGM purple appears exactly once,
on the crash-screen section, because branding/README.md says a colour used
everywhere means nothing. The typefaces are Roboto and JetBrains Mono, both
already in ports/ and both requested from the system rather than downloaded --
a font file would outweigh the rest of the site.
The boot log in the hero is real lines from a real boot. The script is
decoration and the page is complete without it; it does nothing at all under
prefers-reduced-motion.
The feature tags (runs / in progress / designed) are a promise, and the
README says so: anything marked `runs` is in the tree and works today.
