mind-body

The Mind's body: the control store, the launch primitive, the mind-wake one-shot and the mind-self-run actuator.

mind-self-run --instance <slug> [--endpoint rudp://<ip>:<port>] runs inside mind-self@<instance>. It finds her one open Self run, starts claude over stream-json with a fixed argument list, asks for the flush once at the context ceiling and stops a child that outlives the flush (SIGINT, then SIGTERM and SIGKILL). It exits 0 when the child exited 0, 1 otherwise, 3 when she has no single open Self run and 2 when the arguments are wrong or the mind cannot be reached.

The container lane

tests/wake.rs holds one #[ignore]d test that runs the real mind-wake binary against the real huginn-daemon and a real store at the brake's root, and asserts that the host a run records is the kernel's hostname. It writes /etc/gamecult/minds, so it runs in a container only (/.dockerenv), as root, with the daemon built beside the binary. A plain cargo test skips it, and so does cargo mutants, which therefore reports the three host() mutants in src/bin/mind-wake.rs as missed. The lane that kills them:

cargo build -p huginn-daemon -p mind-body --all-targets \
  && cargo test -p mind-body --test wake -- --include-ignored

On Yggdrasil, run it through the verify stopgap in the Rust image (ygg-verify.sh <worktree> <rev> rust '<the command above>').

Mutation testing of the waker needs the glob form, because -f src/wake.rs finds no mutants in this workspace: cargo mutants -p mind-body -f "**/src/wake.rs" -f "**/src/bin/mind-wake.rs". The second glob reaches host(), whose mutants only the container lane kills.

The actuator has its own ignored test, the_real_bin_finds_her_run_... in tests/self_run.rs: the real mind-self-run against the real daemon with a fake claude first on PATH. It needs the daemon built beside the binary and a POSIX shell, not root:

cargo build -p huginn-daemon -p mind-body --all-targets   && cargo test -p mind-body --test self_run -- --include-ignored

Mutation testing of the actuator, with the globs that reach the library and the binary: cargo mutants -p mind-body -f "**/src/self_run.rs" -f "**/src/bin/mind-self-run.rs". The binary's mutants are killed only by the lane above.
