`tom_som_go_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 module, meta/, schemas/ and go.mod).

Each sample is its own package main in its own subdirectory (Go allows only one main per directory). Every sample reaches the generic runtime through the fixed import path tom_som_go_runtime, wired by the relative replace directive on the runtime in this module's go.mod, so the samples are portable across checkouts.

Build & run

From the module root:

go run ./examples/a_typed_access
go run ./examples/b_generic_document
go run ./examples/c_reflection_metadata

The samples build, vet and test together with the module:

go build ./...
go vet ./...
go test ./...

Sample	File	Access path
(a) Typed object-model	a_typed_access/a_typed_access.go	The generated typed facade — named accessors, nested-section navigation, the typed SomList collection.
(b) Generic document	b_generic_document/b_generic_document.go	The language-independent generic runtime — string paths into a sparse store, plus JSON / YAML serialization.
(c) Reflection / meta-data	c_reflection_metadata/c_reflection_metadata.go	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 counterparts in tom_som_dart_v0/example/, tom_som_python_v0/examples/, tom_som_javascript_v0/examples/ and tom_som_typescript_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).
