Each command declares which fields it accepts and which changes it can apply; the resolution process has one implementation.</p> <p><strong>Status (2026-11-11):</strong> This approved design is implemented: six CLI/environment inputs, command integration, inventory generation, source tracking, <code>SPEC</code> display, and in-place root growth. These changes remain unreleased. Working-tree inventories default to 1 vCPU / 2 GiB; released Barn 1.1.0 still defaults to 2 vCPU / 4 GiB.</p>
