Records the direction set out today -- snapshots, scrub, compression and
encryption for SchFS; one shared home for the format; a unified second
stage under both firmwares; audio -- and the two requests that were
pushed back on, with the reasoning, so neither gets re-litigated from
scratch: 128-bit addressing buys nothing over the 64 ZB already
addressable, and SchFS cannot live in projects/ because the kernel has to
mount it to boot.

Records that the GUI stack moved ahead of the installer, that Schcom v0
runs and how to prove it, the decisions behind the protocol shape
(Wayland-shaped, MIT so linkable, shm id rather than SCM_RIGHTS for now),
and the one-display-device trap in the screendump test.

Records the four bugs between "boots to cpu0: starting" and "boots to an
interactive shell", the new ioremap rule for device registers, and what
the disc now contains -- including that it is still not a live CD, and
what that would take.

Neither is Fedora-specific. A different host and a freshly built
userland simply drove code that Windows never reached.
tools/mkfs.c did not compile at all. The DT_UNKNOWN/DT_DIR/DT_REG
fallbacks sat above <dirent.h>, so on glibc -- which spells them as
enumerators -- the #ifndef asked before the header was read, always
answered "missing", and then the header's own enum expanded to
`enum { 0 = 0, ... }`. Move the fallbacks below the include. The
include cannot move up instead: it has to follow the #undef that ends
the `#define dirent schfs_dirent` block.
getstackpcs() page-faulted. It dereferenced rbp[1] without validating
rbp, and the guard rejected 0xffffffff -- dead code on x86-64, already
caught by the KERNBASE test -- while the value that actually turns up
is all-ones, which is above KERNBASE. rbp[1] then wrapped to 0x7 and
took trap 14. `cp` panicked the kernel every time. Bound rbp from
above and require 8-byte alignment.
That second one masks other bugs: getcallerpcs() runs on every lock
acquisition and again from the trap handler, so a walker that can
fault replaces a real diagnosis with a bogus one.
Baseline on the Fedora laptop is now green: make ports, make,
make schfs-check including the round-trip that had never run, and
bootcheck at 27/27 plus 108 [ok] across the extended suites.

README's layout predated the BIOS/UEFI split. moving-to-linux.md now
says what is gitignored and therefore absent from a clone: dist/ holds
61 MB of upstream tarballs, so copy it or let the build re-fetch them --
make ports verifies each against a known SHA-256 either way.
Claude Code keeps per-project memory at <home>/.claude/projects/<key>/,
where <key> is the project's absolute path with every separator and the
drive colon turned into a dash. That makes it both rename-fragile and
machine-specific, and this project has hit each of those once:
- D:\DEV\Schunix -> D:\DEV\SchOS changed the key, and 43 memories were
invisible until moved across by hand.
- Development happens from Windows and from Linux, and each looks in a
different place for the same checkout.
Committing .claude/memory/ fixes both -- git carries it across renames
and between hosts -- and `import` puts it wherever the local machine
expects. .claude/settings.local.json stays ignored: those are per-machine
permissions.
The colon maps to a dash rather than being dropped. Deleting it gives
D-DEV-SchOS, which matches nothing and silently finds zero memories; that
was the first attempt. On Git Bash the key comes from `cygpath -w`,
because Claude Code is a Windows program and sees D:\DEV\SchOS, not
/d/DEV/SchOS.
