Runtime Surface

Aether is a workspace, not a single binary.

Component	Path	Active role
Language crate	crates/aether-lang	Lexer, parser, AST, interpreter, Titan VM, exporters
Core crate	crates/aether-core	Manifolds, topology, ML primitives, governors, state
CLI crate	crates/aether-cli	REPL, script runner, syntax checker
Kernel crate	crates/aether-kernel	no_std sparse scheduler, loader, allocator, boot scaffolding
Compatibility core	crates/aegis-core	Legacy compatibility surface

Runtime Objects

The interpreter stores named variables in a map from identifiers to runtime values. Handles are used for manifolds, blocks, classes, and objects so large state stays inside interpreter-owned arenas.

identifier -> Value::Manifold(handle) -> manifolds[handle]
identifier -> Value::Block(handle) -> blocks[handle]
identifier -> Value::Persistence(diagram)
identifier -> Value::Tensor(tensor)

Extension Boundary

New language-level features should pass through the same path:

1. token kind;
2. AST node;
3. parser rule;
4. interpreter behavior or VM opcode;
5. tests;
6. documentation status update.

Skipping one stage creates a parsed-only feature or a runtime-only feature.
