Prepare a clean GitLab submission snapshot from the Primordium handoff kernel while excluding local build outputs and generated ELF artifacts. The repository now contains the source tree, linker scripts, build entrypoints, local test materials, and required submission-facing documentation.

Constraint: Official evaluation expects make all to produce kernel-rv and kernel-la from source.

Rejected: Commit Docker-generated kernel-rv/kernel-la artifacts | evaluation should build from source and binaries make the repository noisy.

Confidence: high

Scope-risk: moderate

Directive: Keep generated disks, kernels, target directories, and temporary ELF files out of version control.

Tested: Docker os-contest image make all generated kernel-rv and kernel-la successfully.

Not-tested: Full LoongArch usermode test matrix remains incomplete; known TLB/usermode issue still needs follow-up.
