What’s published
Firmware is GL.iNet's GPL OpenWrt fork for the Siflower SF19A28 platform; Siflower publishes an SF19A28 datasheet, but no router PCB schematics, Gerbers or BOM are public.

Confirmed via GitHub API recursive tree listing of gl-inet/openwrt branch openwrt-18.06-siflower: it contains linux-4.14.90-dev/.../arch/mips/boot/dts/siflower/sf19a28_fullmask_gl_sf1200.dts -- a devicetree literally named for this device on the SF19A28 chip, which is strong direct evidence this branch is GL.iNet's real GL-SFT1200 firmware source (kernel-level only; no schematic/Gerber/BOM files anywhere in the org per a separate code search). Siflower's own datasheet PDF (siflower.com.cn, verified 200) is filed as 'SF19A2890', a closely related part-number variant of SF19A28, not necessarily byte-identical -- noted as a naming variant rather than treated as a mismatch.
