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.

name: schunix-verify-by-driving-shell description: "Boots to a prompt" is not a passing test for Schunix — drive real commands over the serial console metadata: type: feedback
Reaching init: ready (pid 1) and a # prompt proves almost nothing about
Schunix. A filesystem change shipped looking "verified" that way and the user
found the breakage by typing one command.
Why: nothing in the boot path opens a file from /bin or reads a
non-root inode. An image with corrupt inodes boots to a perfectly healthy
prompt and dies on the first ls.
How to apply: after any change to tools/mkfs.c, the on-disk format, or
kernel/fs/*, drive actual commands and read the output. QEMU's serial line is
an input console, but it has no flow control — a burst of piped input loses
about half its characters, and input sent before the shell is up is discarded
entirely. Both problems go away with: wait ~20s for boot, then send one
character every ~0.12s.
send() { s="$1"; i=0
while [ $i -lt ${#s} ]; do
printf '%s' "$(expr substr "$s" $((i+1)) 1)"; sleep 0.12; i=$((i+1)); done
printf '\n'; sleep 7; }
sleep 20; send "ls"; send "ls /bin"; send "cat /etc/motd"
Pipe that into qemu ... -serial stdio -display none and read the log. ls,
ls /bin and cat on a real file are the minimum bar.
