wasm-vm

✅ Level 1 — architecturally RISC-V (native + WASM). The complete RV64GC + privileged machine passes the full riscv-tests suites AND RISCOF architectural compliance (395/0) against the canonical RISC-V Sail reference, with zero allowlist/exclusion entries. Reproduce: make level1-gate (report: docs/level1-report.md; tag level-1).

✅ Level 2 — unmodified Alpine riscv64 boots to a login shell IN THE BROWSER (E2-T26 capstone). Fetch the Linux kernel + 512 MB Alpine ext4 image, boot from virtio-blk in xterm.js to a login: prompt, log in as root, and use vi/top/scripts/poweroff. Run it yourself:

cargo build --release -p wasm-vm-cli
bash tools/build-rootfs.sh            # build the Alpine ext4 image (once)
bash tools/demo-capstone.sh 8000      # builds the wasm bundle, serves, prints the demo script
# → open http://localhost:8000/ → click "Boot Alpine" → wait for login: → root (empty password)

The lighter busybox boot ("Boot Linux") also runs on the deployed page; Alpine's 512 MB image is local-only via serve-dev. Capstone e2e: web/tests/capstone.spec.js.

A from-scratch virtual machine in Rust, compiled to WebAssembly, that boots real unmodified Linux (Alpine riscv64) in a browser tab — target experience: a complete clone of webvm.io/alpine.html, then beyond it to a full GUI desktop and self-hosting.

• ROADMAP.md — the guiding trajectory: seven stacked levels (a Kardashev scale for in-browser Linux), what each level gets you, and the capstone threshold that gates each.
• AGENTS.md — how agents drive the repo: the worker/verifier loop, what counts as evidence (rr traces + guest instruction traces), and the verifier charter.
• tasks/ — the full work breakdown: one folder per epic, one file per task, tasks/QUEUE.md as the global priority queue.
• tools/build_queue.py — regenerates tasks/QUEUE.md from task frontmatter.

Execution model: one task at a time, top of queue, and no task is done until an adversarial verifier fails to refute it (protocol in tasks/README.md).

Sibling project: ~/Dev/almostnode emulates Node.js APIs in the browser; wasm-vm emulates the hardware.
