 This page is auto-generated from Perry's compile-time API manifest (`perry-api-manifest::API_MANIFEST`). It is the source of truth for what `perry compile` accepts; references to symbols not listed here produce `R005 UnimplementedApi` (issue #463). Stubs (#464) are flagged ⚠ — they link cleanly but no-op at runtime on the chosen target.
