Linehu 1e74ee9fab feat: U5 land deterministic chacha20 KAT (RFC 8439 2.4.2) 
- test/gen_chacha_kat.py emits KAT from RFC 8439 section 2.4.2 mapped to the impl's 64+64 counter/nonce layout; expected bytes cross-checked against pycryptodome (independent impl) and the official vector: 10f1e7e4d13b5915... byte-exact
- verdict: the 'intermittent chacha20 KAT FAIL' referenced in FUCK comments was a phantom — that test was never merged into this tree; the implementation itself matches RFC byte-for-byte
- selftest now runs KAT + page-MAC determinism checks at selftest=2; full SELFTEST PASS in QEMU (.build_tmp/qemu_serial_u5kat.log)

Linehu 7925c09677 feat: U4 ciphertext page dump tool 
- utrw/debug.c: utrw_debug_dump_page(slot,page,offset) — kernel debug-privileged dump of 64B ciphertext + decrypted plaintext hex to serial (PCKC key derive, no capability path)
- selftest demo: dump at offset 128 shows plaintext 'deshab utsm sealed memory selftest' vs unrelated ciphertext; SELFTEST PASS (.build_tmp/qemu_serial_u4dump.log)

Linehu b76e8f1556 feat: U2 UTRW slow path real branches 
- slow_path.c: KEY_MISS -> PCKC re-derive (retry OK); EPOCH -> refresh cap epoch via out_cap (retry OK); STALE_CAP permanent; MAC_FAILED/POISONED -> PCKC invalidate + DRR fault report; RETRY passthrough
- status.h: add UTSM_ERR_MAC_FAILED (-11); utrw.h: slow path takes cap/rights/offset/len/reason + out_cap
- selftest: EPOCH refresh + KEY_MISS re-derive + POISONED passthrough coverage, full SELFTEST PASS in QEMU (.build_tmp/qemu_serial_u2slowpath.log)

xyou efa626ed17 feat: Phase 1 网络端到端打通 + FirstInit/Login/DevMode 完善 
- 用户态共享网络协议栈 CODE/tools/net_stack.h（eth/ARP/IPv4/ICMP/UDP-DNS/TCP static inline，轮询模型）
- shell 内建 ping/curl/run 命令；ping.elf/curl.elf 对齐 net_stack.h 真实协议栈
- shell dev_mode 串口镜像（g_serial_mirror）便于自动化验证
- DSK 启动流程：firstInit.txt 双行格式（firstInit + dev_mode），dev_mode=1 触发 shell 自动回归测试
- FirstInit 完成→持久化 USER.CONF + 翻转 firstInit 0->1（保留 dev_mode）
- firstInit=1 时 DSK 加载 login.elf 进行用户选择 + 密码校验后再进 desktop
- 新增 CODE/login/ 登录应用、CODE/DKM/dkm_shared.h、Logo.png
- ahci/e1000/virtio_net/fat32/console_fb 驱动更新；utsm serial/block/dsk_loader 调整
- build.ps1 打包 ping.elf/curl.elf 进 SATA FAT32 根目录
- 移除 CODE/tools/bash（与 shell.elf 重复）
