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.

| schunix-doom-acceptance-test | The full-stack acceptance test (a ported 1993 shooter) was removed on 2026-08-08 — what it found, why it went, and what to do instead. |
|
Removed 2026-08-08 at Nexoniarz's request ("we don't need it anymore because
we know that doom works"). Do not re-add it, and do not reintroduce the name into
comments — they also asked for trademark words to be cleared from the tree, and
it is now at zero references outside dist/.
Deleted: ports/fbdoom/, tools/doomtest.ps1, tools/doomtest2.ps1, the
doom/doomtest/doom-uninstall Makefile targets, NOTPORTS := fbdoom.
The WADs were moved, not deleted — dist/wads/ — because doom1.wad was a
shareware download that existed nowhere else in the tree, while freedoom1.wad
is recoverable from dist/freedoom-0.13.0.zip.
What it was worth, because the shape is worth repeating. A large program
somebody else wrote, exercising /dev/fb0, evdev, mmap, the ELF loader,
gettimeofday and a fixed-rate tic loop at once, is harsher than any in-house
test because it was not written against our bugs. It found: the
fcntl(F_SETFL, O_NONBLOCK) no-op; the evdev backlog replayed to each new
opener; and the missing EVIOCGRAB. All fixed, all now covered by
tools/bootcheck.ps1 -Evdev / -Sock — which are narrower and do not prove
the whole stack composes. That is the honest cost of the removal.
Why it went beyond being asked: ~100k lines of GPL-2.0 engine on
non-redistributable shareware data, whose safety depended on two separate
opt-outs (NOTPORTS and RAMDISK_EXCLUDE) both staying correct — and the
ramdisk is linked into the kernel binary, so a slip there makes the kernel
undistributable, not just the image. See schunix-ramdisk-root-sizing and
schunix-licensing.
Two techniques from it that transfer:
- Assert on pixels, not log lines. A log-only harness once passed on a blank
screen.
tools/splashshot.ps1counts distinct colours for this reason. - For a crash inside a program you did not write, run
llvm-nmagainst the faultingripto get a function name, then use the fault offset to identify the exact field. "Null pointer plus 24" alone is nearly useless.
Both lessons are written up in docs/roadmap.md Phase 7 and
docs/architecture/kernel-history.md §10 and §12, with the program genericised.
