/**
 * Regression tests for the current workspace lock policy: every
 * resolved workspace is held exclusively for the duration of the run.
 * Pi's coding tools always include bash/write/edit, so there is no
 * read-only category where concurrent runs are safe; teammates
 * sharing one repo queue through the wakeup table instead of racing
 * the filesystem.
 *
 * See `resolve-workspace.ts` for the full rationale.
