/**
 * Golden tests for the swarm coordination layer.
 *
 * Every case runs against a real on-disk sandbox under {@link os.tmpdir} so the
 * kernel's lock + atomic-publish + schema-validate machinery is genuinely
 * exercised — no stubs for the filesystem, no network, no model. Teammate agents
 * are *scripted fakes*: each implements the runtime {@link Agent} surface but its
 * `submit` resolves to a canned snapshot, so a coordination round runs
 * deterministically.
 *
 * Five behaviours are pinned, mirroring the load-bearing guarantees of each layer:
 *
 *   1. {@link JsonCell} concurrency — two parallel `mutate()`s serialize with no
 *      lost update; a bad shape is rejected by the schema.
 *   2. {@link TicketBoard} — a dep edge gates readiness; claim is atomic;
 *      completing a dep unblocks its dependent; a cycle is rejected.
 *   3. {@link Channel} — per-reader cursors deliver each envelope exactly once and
 *      independently; the codec rejects an unknown type.
 *   4. {@link Crew.runRound} — two scripted members complete two tickets; the
 *      activity timeline records the coordination events.
 *   5. {@link Workspace} — a real git worktree round-trips when git is available;
 *      the assertion soft-skips (does not fail the suite) when git is absent.
