Part 1 — Author Surfaces

Status

• Normative baseline: Part 1 defines the humane authoring surfaces for Rhoe Language 0.9.0.
• Part 1 is governed by Part 0 and may not redefine ontology, registries, or canonical serialization.

Scope

• rhoemd overview and doctrine
• core block and inline syntax
• matter, carrier, and structural directives
• stageFrame source surface and deprecated slide compatibility
• non-stage carrier surface families
• formal grammar and tokenization
• rhoedsl reference
• round-tripping and lowering

Part-Wide Commitments

• rhoemd remains the primary humane author surface.
• Canonical rhoemd is carrier-aware and frame-primary.
• rhoedsl remains a humane structural mirror of the same AST.
• Canonical writers emit canonical forms, not compatibility forms.
