soma clean-checkout gate — row 39

Property #39 — every phase-1 component builds and tests from a clean checkout of its default branch. cyber/launch lists soma in the phase-1 dependency closure ("the mind's tasks in cyb"); the 2026-09-22/23 sweep that found row 39 broken elsewhere (bbg, cybergraph, foculus, mudra, neuron, nox, prysm, zheng, true-cyber, glia, honeycrisp, rune, vault, radio) did not examine soma. This measures it directly.

finding

origin/main at 7cfa6f8 has no Rust code at all: no Cargo.toml anywhere in the tree, so cargo check/cargo test have nothing to run. The two crates the rest of the graph already refers to — soma-kernel (kernel/, depended on by nothing yet outside this repo) and soma-agent (agent/, path = "../agent" from kernel/Cargo.toml) — exist only on the pushed branch origin/docs/foculus-links (b0d5d42, 5 commits ahead of main, diff +6330/-167 across agent/, kernel/, audit/, specs/, plus a soma-spec.md rewrite). That branch already has an open pull request, soma#1 (titled "docs: migrate sync to foculus" — the title describes only the doc-rename commit, not the kernel/agent code the branch actually carries), unmerged since 2026-09-23.

This is a more severe row-39 case than the pin/path drift found in the other 14 repos: it isn't that soma fails to build clean, it's that the branch the release train would build (main) carries no implementation to check at all. The gate can't even run.

Merging soma#1 closes this row's soma slice — it is the same content this audit measured, already reviewable. Until then, soma is phase-1's one component where row 39 has no code-side fix available to a worker: the fix is merging a PR that already exists, not opening a new one.

re-verified 2026-10-17

origin/main is still 7cfa6f8 and still has no Cargo.toml (git ls-tree -r --name-only origin/main | grep -c Cargo.toml → 0). The kernel and agent still sit on origin/docs/foculus-links, now soma#1 titled "DECIDE: docs: migrate sync to foculus" and waiting on the owner; feat/kernel-live-stream (soma#4) and chore/neuron-auth stack on it. Row 39 in cyber/launch is still open; the finding stands.
