pub const TOOL_FOLD_NAMESPACE: u64 = 0xA1F0_0001_0000_0000;Expand description
Namespace for the per-buffer tool-call fold provider id. OR’d with the
buffer’s id (low 32 bits) so the source is distinct in the registry —
FoldOverlayService::add_source keys removal on the id. Distinct high bits
from REASONING_FOLD_NAMESPACE so a buffer’s two AI fold sources register
under different ids (they coexist over disjoint line regions). Distinct from
diff’s 0xD1FF_* and multibuffer’s 0xBBBB_* namespaces.
