renderLayer.shared

Layer-name normalization shared across the renderLayer toolbox.

• toNames(layers, label) — a name, an array of names, or a space-separated string ("shell debug") → an array of names. Raises on anything else and on an empty result, naming the calling tool.
• readNames(value) — an entity's renderLayer string → an array of names.
• allLayers() — every layer interned in this world, ordered by bit, each { name, bit, builtin }.

Every tool in the toolbox speaks names; the bitmask stays behind the entity-proxy methods and this module.
