Adds xce_sched_core_save_snapshot()/xce_sched_core_load_snapshot(), split across snapshot.c/snapshot_wire.c/snapshot_load.c (800-line cap) along real save/load/shared-helper boundaries. Serializes the full core state (config, jobs, queues, workers, resources, resvals, users, projects, prng_seed, internal_state) into/out of sched_snapshot_data_t (task 7.3's committed C mirror of the capnp SnapshotData struct) as plain in-memory structures -- no wire encoding here, that's a later task. After load, rebuilds the picker's private state by re-invoking its state-change hooks (queue updates, then job pushes) against the restored core state, matching xce_core_push_events()'s own hook-firing order; picker-private state itself is never stored in the snapshot. Adds a new prng_seed field to xce_sched_core_t -- requirements.md/ design.md both presuppose it but no prior task added it. Seeded to 0, no PRNG consumer wired yet (deliberately out of scope). Cross-core behavioral-equivalence proven directly: two independent cores, each with its own registered picker, save on one and load into a freshly-initialized other, both driven through an identical real session, decision sequences asserted identical in order. Found and fixed two real bugs along the way: a missing prng_seed restore in this task's own new code, and a genuine guard bug in already-committed core.c (sched_get_user()/sched_get_project() treating key_find()'s expected -ENOENT as fatal, silently breaking get-or-create for any new name) that also affects the live production path (make_sched_job(), JOBS_PUSH) -- a narrowly-scoped two-line fix, independently traced to the primitive level and confirmed correct by review.

1. commit 规则
- 每个人 fork 自己的 branch， 从自己的 branch 做 PR，review 完再 commit
2. code format
2.1. C
推荐使用 clang-format，公共配置放在源码里面 xce/.clang-format
（理论上直接使用源码里面 xce/.clang-format 文件格式不会变）
2.1.1. vscode 可以在配置中加上如下内容
"C_Cpp.clang_format_style": "WebKit",
"C_Cpp.clang_format_fallbackStyle": "WebKit",
2.1.2. vim & emacs
clang-format -style="{BasedOnStyle: webkit}" -i XX.c
2.2. golang
使用默认 gofmt
3. build environment and build (example of ubuntu)
3.1 build environment
- Install nix package management tool
sh <(curl -L https://nixos.org/nix/install) --daemon
- Edit /etc/nix/nix.conf to make sure
experimental-features = nix-command flakes
sandbox = true
sandbox-fallback = false
substituters = https://mirrors.ustc.edu.cn/nix-channels/store https://cache.nixos.org https://cache.nixos.org/
trusted-users = root <your account>
make sure that you have restarted nix-daemon service after you have changed /etc/nix/nix.conf
- Install socat and config ssh (for clone by ssh protocol)
nix profile add nixpkgs#socat
.ssh/config
Host gitea.shenrs.eu
HostName gitea.shenrs.eu
IdentityFile ~/.ssh/id_ed25519
ProxyCommand socat - openssl-connect:gitea.shenrs.eu:2022,snihost=gitea.shenrs.eu,verify=0
3.2 checkout source code
3.3 build (for package and release)
cd xce/src
# for build debug version
nix build --option sandbox false .#xcecore_debug
# for normal build
nix build --option sandbox false .#xcecore
You can find the generated binaries at =result= directory
3.4 build (for daily develop)
cd xce/src
nix develop
# using meson to generated build configuration (debug and address sanitize)
meson setup build --buildtype=debug -Db_sanitize=address
# run meson to build
meson compile -C build
# The generated files will be in build/
3.5 build AppImage package
cd xce/src
nix bundle --bundler github:ralismark/nix-appimage --option sandbox false .#xce
This will create all in one AppImage file which contains everything for package delivery.
4. misc
4.1. Windows remap ctrl and alt key
create a reg file, e.g. remapkey.reg
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map"=hex:00,00,00,00,00,00,00,00,05,00,00,00,38,00,1d,00,1d,00,38,00,38,e0,1d,e0,1d,e0,38,e0,00,00,00,00
then double click remapkey.reg to import it. Restart OS.
