roadmap-4ch8f

roadmap-4ch8f is an agent for Claude Code from Verified-zkEVM/evm-asm. It costs 0 tokens per session (4,273 once invoked), scanned A, original, MIT.

A roadmap for proving that the real stateless Ethereum guest produces the correct result, with every guest routine backed by a verified specification. It also tracks tests against execution-specs, the reference implementation of Ethereum execution rules.

In plain words
What is it for?
Use it to choose the next verification task, port a routine from the reference specification, review a change, and run the required proof and conformance checks.
Why use it?
It gives agents a route through the remaining proof work and identifies the files, recipes, and checks that carry the main theorem. This reduces guesswork when taking the next task.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md).

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

roadmap-4ch8f scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The 4ch8f roadmap — how to take run_stateless_guest verification to conclusion

Audience: the agent (any capability tier) picking up the next bead of epic evm-asm-4ch8f. This page is the map; it tells you which bead to pick, which recipe applies, which gates you must run, and where every load-bearing definition lives. Read it top-to-bottom once; afterwards jump via §7.

The goal, in one sentence: prove runStatelessGuestSound cr fuel fr execute (EvmAsm/Stateless/EntrySpec.lean) for the real guest image — every routine of the RISC-V stateless_guest replaced by a verified triple — while the empirical harness scripts/codegen-eest-stateless-check.sh (EEST conformance, [email protected] fixtures) keeps passing at every step.

Companion pages (do not duplicate their content; link into them):

  • docs/agents/port-playbook.md — the per-routine port workflow (kit → spec → proof → port-check.sh). This is the recipe for ~80 % of remaining beads.
  • docs/agents/review-playbook.md — how to review a 4ch8f PR (the gates CI does NOT run, the adversarial checklists, the known-hole catalog).
  • docs/agents/top-theorem-ledger.md — obligation rows from the statement down; update rows as beads close.
  • docs/4ch8f-top-spec.md (the statement + trust boundary), docs/4ch8f-interp-strategy.md (interpreter/dispatch/frames), docs/4ch8f-crypto-strategy.md (crypto kernels + field-arith library), docs/sasm-design.md (the SAsm framework itself), docs/agents/proof-patterns.md + docs/agents/tactics-deep.md (tactic craft).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

roadmap-4ch8f is an agent published in the GitHub repository Verified-zkEVM/evm-asm (55 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 4,273 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
