`tom_som_rust_v0` — runnable samples

Three runnable samples covering the three access paths to a TomSpecs Spec Object Model document (som_multiplatform_spec_model.md §6). They are hand-authored and preserved across generate_som regeneration (the generator only rewrites the crate root src/lib.rs, meta/, schemas/ and Cargo.toml).

Each sample is a single-file Cargo example under examples/. Every sample reaches the generic runtime through the fixed crate name tom_som_rust_runtime, wired by the relative path dependency on the runtime in this crate's Cargo.toml, so the samples are portable across checkouts.

Build & run

From the crate root:

cargo run --example a_typed_access
cargo run --example b_generic_document
cargo run --example c_reflection_metadata

The samples build and test together with the crate:

cargo build --examples
cargo test

Sample	File	Access path
(a) Typed object-model	a_typed_access.rs	The generated typed facade — named accessors, nested-section navigation, the typed SomList collection.
(b) Generic document	b_generic_document.rs	The language-independent generic runtime — string paths into a sparse store, plus JSON / YAML serialization.
(c) Reflection / meta-data	c_reflection_metadata.rs	The value-free reflection surface — load meta/spec_model.meta.json into a SpecModel , enumerate roots/fields, resolve paths to model nodes.

All three describe the same document shape, and produce output equivalent to their Dart/Python/JavaScript/TypeScript/Go counterparts in tom_som_dart_v0/example/, tom_som_python_v0/examples/, tom_som_javascript_v0/examples/, tom_som_typescript_v0/examples/ and tom_som_go_v0/examples/ — illustrating that the typed facade (a) is a thin, type-safe surface over the exact generic store (b), whose schema is described by the reflection model (c).
