+# v33 完美固件源码包
+
+对应 sysupgrade-v33.bin（md5 57d43f1a56c66fafd5c62e8846641232）。
+
+## 包含文件（相对 ImmortalWrt 源码树根）
+
+### package/mtk/ — MTK 闭源驱动层补丁
+- `applications/mtwifi-cfg/files/mtwifi-cfg/mtwifi_cfg` — 5G/HE160 双分支写 VHT_Sec80_Channel=155
+- `applications/mtwifi-cfg/files/mtwifi.sh` — detect_mtwifi 诚实 UCI（idx=1=5g/HE160, idx=2=2g/HE40）
+- `applications/mtwifi-cfg/files/netifd/mtwifi.sh` — v33 关键补丁：setup 完成后 deferred 后台检测 dat MacAddress 与物理 netdev MAC，重发 wireless_add_vif 上报物理 ifname
+- `applications/luci-app-mtk/luasrc/controller/mtkwifi.lua` — 顶部空 index() 禁用 MTK 私有面板
+
+### package/mtk/drivers/wifi-profile/
+- `files/mt7981/l1profile.dat` — 主次顺序 b0;b1（出厂值，未改动）
+
+### feeds/luci/
+- `modules/luci-mod-network/htdocs/luci-static/resources/view/network/wireless.js` — Overview/Modal SSID 读 iwinfo、reload-block 补丁、freqlist/txpowerlist 改传物理 ifname
+
+### files/ — 烤入 squashfs 的配置与脚本
+- `etc/uci-defaults/99-custom-config` — 首启 UCI 默认值（诚实标签 + turboacc tcpcca=bbr）
+- `etc/wifi-band-verify.sh` — log-only 验证脚本
+- `etc/rc.local` — 开机兜底（检测 vxlan0，缺失重触发）
+- `etc/hotplug.d/iface/30-mss-clamp` — MSS clamp 持久化
+- `etc/hotplug.d/iface/40-wg-track` — WG 隧道状态跟踪
+- `etc/sysctl.d/99-bridge-nf.conf` — bridge-nf-call-{ip,ip6,ar}tables=1
+- `etc/config/{wireless,firewall,dhcp,turboacc,dropbear,network}` — 7 个核心 UCI 配置全部烤入（**network 已脱敏：private_key 与 preshared_key 替换为占位符，使用前必须重新生成 WG 密钥对**）
+
+### 顶层
+- `netifd-wireless.sh` — `/lib/netifd/netifd-wireless.sh` (wifi-scripts 包)
+
+## 刷入流程
+1. 克隆 padavanonly fork 的 ImmortalWrt-Actions 源码树到 build server
+2. 用本包覆盖对应路径
+3. `make -j4` → `bin/targets/mediatek/filogic/immortalwrt-mediatek-filogic-cudy_tr3000-v1-ubootmod-squashfs-sysupgrade.bin`
+4. FIT 镜像雕刻验证：`OFF=$(grep -abo "hsqs" image.bin | head -1 | cut -d: -f1); dd if=image.bin of=root.sqfs bs=1 skip=$OFF; unsquashfs -d sq root.sqfs`
+5. U-Boot TFTP/网页刷入（**绝不用 sysupgrade**）

+# v21 2026-07-21: HONEST labels (UCI now matches physical reality).
+# Driver binds profiles by MacAddress match, NOT by l1profile order:
+#   b0.dat (MacAddress=2.4G eeprom MAC) -> rax0 netdev (2.4G HW)
+#   b1.dat (MacAddress=5G eeprom MAC)   -> ra0 netdev  (5G HW)
+# v21 additionally swaps INDEX0_profile_path in l1profile.dat to
+# "b1.dat;b0.dat", so l1dat_parser maps: idx=1 (ra0) -> b1.dat,
+# idx=2 (rax0) -> b0.dat. Result: each UCI section writes the DAT that
+# the driver actually binds to its phy, so UCI band/ssid can be honest:
+#   idx=1 (ra0,  5G HW):  band=5g HE160 ch 36   ssid=ImmortalWrt-5G
+#   idx=2 (rax0, 2.4G HW): band=2g HE40  ch auto ssid=ImmortalWrt-2.4G
+# Kernel DBDC merge quirk (unchanged): VHT_BW / VHT_Sec80_Channel for
+# ra0's slot are taken from b0.dat, so mtwifi_cfg still forces
+# VHT_BW=2 + VHT_Sec80_Channel=155 into the band==2g profile.
+# Validated live on v20 2026-07-21: ra0 2401Mbps HE160 ch36,
+# rax0 HE40, DBDC_card0.dat identical to v20 working state.
