Guest /dev/fd links; jobs are told what they build
Andy McCall ·
✔ c4285535b03a
Build image for Rust and Node jobs (images/rust: toolchain, rustfmt, clippy, Node 24, vendored crates, offline cargo); flow-init finds the program in the job's PATH (glibc's execvpe used PID 1's own); network "loopback" in M0
Andy McCall ·
✔ eb5c4db673e5
Ephemeral scratch mounts in M0: ephemeral://tmpfs and ephemeral://disk (a sparse disk per job), checked targets and sizes, in the canonical job and the receipt; flow-init mounts them for the job's user; make deploy-runner
Andy McCall ·
✔ fc10d9e80383
OxygenFlow M0: pipeline parser and canonical job graph, receipts, the runner API types, flow-init, the Firecracker tier, flow check, run, rootfs import and runner
