The only rootfs on this track came from clawmates/agent-terminal:dev. Mounted,
it held git and nothing else: no claude, no node, no cargo. A VM booted from it
looks perfect and cannot run a mission, so B4.5 could have been written and
never verified.
images/agent-toolchain — the shared mission toolchain (node 22, git, rust +
cargo-audit, gitleaks/trivy/semgrep, tea/gitea-mcp), lifted from the proven
deploy/clawmates-runtime image minus the zeroclaw daemon: a microVM mission runs
the direct-session model, so there is no daemon to host. A base image rather
than three self-contained Dockerfiles because this layer is ~3 GB and the real
risk is scanner and toolchain versions drifting between per-CLI images — the
evaluator runs the project's own suite to check a claim, so `cargo` present in
one image and absent in another makes the same mission pass or fail by backend
with nothing saying why.
images/agent-claude — plan A6, first of three: the pinned CLI and its env
contract only, so bumping Claude Code does not rebuild the toolchain and cannot
disturb agent-kimi / agent-glm. HOME=/root with an empty .claude for B4.4 to
inject into; no ANTHROPIC_API_KEY, since it silently overrides the subscription
OAuth we already pay for.
Both the builder and the node selftest now ASK the guest for the CLI the image
is named for, instead of trusting the name. `required_cli` maps claude/kimi/glm
to a probe; an unrecognised backend reports unchecked and prints SKIP rather
than passing quietly.
Verified on tank:
- rootfs-claude.ext4 boots; git, node, cargo, a real git commit all work
- `claude --version` → 2.1.220 over vsock, in both the builder and
`--vm-selftest` (11/11, create 1498 ms)
- negative control: the same builder run against agent-terminal with
FC_CLI forced reports `cli rc=127 claude: not found` and exits 1, so the
green result above is a measurement and not a default
- `claude -p hello` fails with "Not logged in · Please run /login" — the CLI
runs headless in the VM, and B4.4 only has to supply the credential
- no leaked firecracker processes or vm dirs afterwards
437 tests pass, clippy clean.
