Add module TYPES/VALUES, DataElement concern, TermComp elements, RubyDoc, and comprehensive specs

- Add Tbx::DataElement shared concern (DRY) for data-category attributes
  with InlineContent sub-concern for entity.noteText elements
- Add Tbx::Modules::{Min,Basic,Linguist,CoreTypes} with TYPES/VALUES
  constants sourced from .tbxmd files
- Add TYPES constants on Admin, AdminNote, Descrip, TermNote, Ref,
  Xref, Transac, TransacNote, Hi composed from module definitions
- Add VALUES constants on TermNote (picklist enums) and Transac
- Add Tbx::TermComp, TermCompGrp, TermCompSec from TermComp module
- Fix Sc model to match core RNG (remove type, subtype, target attrs)
- Add comprehensive YARD RubyDoc on all element classes tracing
  schema/module sources
- Add reference schema files from 12 LTAC-Global repositories
- Add 119 new specs (165 total) covering TYPES/VALUES, DataElement,
  TermComp, and XML round-trips
- Update README with schema/module/element coverage tables
- Update CLAUDE.md with DataElement and Modules patterns

 ## [Unreleased]
 
+### Added
+
+- `Tbx::DataElement` shared concern — DRY module injecting common data-category
+  attributes (id, lang, target, datatype, type, content) via `included` hook
+- `Tbx::DataElement::InlineContent` sub-concern for elements with `entity.noteText`
+  content model (hi, ec, foreign, ph, sc inline children)
+- `Tbx::Modules::Min` — Min module TYPES/VALUES constants (Min.tbxmd)
+- `Tbx::Modules::Basic` — Basic module TYPES/VALUES constants (Basic.tbxmd)
+- `Tbx::Modules::Linguist` — Linguist module TYPES/VALUES constants (Linguist.tbxmd)
+- `Tbx::Modules::CoreTypes` — Core RNG hi type constants
+- TYPES constants on all data-category elements (Admin, AdminNote, Descrip,
+  TermNote, Ref, Xref, Transac, TransacNote, Hi), composed from module hashes
+- VALUES constants on TermNote (picklist enums) and Transac (transaction types)
+- `Tbx::TermComp` — term component element `<termComp>` (TermComp module)
+- `Tbx::TermCompGrp` — term component group `<termCompGrp>` (TermComp module)
+- `Tbx::TermCompSec` — term component section `<termCompSec>` (TermComp module)
+  with TYPES for 5 decomposition methods
+- Comprehensive YARD RubyDoc on all element classes tracing schema/module sources
+- 119 new specs (165 total) covering TYPES/VALUES, DataElement concern, and
+  XML round-trips for all data-category elements and TermComp elements
+
+### Changed
+
+- Data-category elements (Admin, Descrip, TermNote, AdminNote, DescripNote,
+  TransacNote, Transac, Ref) now use `include Tbx::DataElement` instead of
+  explicit attribute declarations
+- `Tbx::TermNote::TYPES` now composes from Min + Basic + Linguist (9 types)
+- `Tbx::Sc` aligned with core RNG: removed type, subtype, target attributes
+  (only id and isolated per RNG)
+- Reference documentation downloaded from 12 LTAC-Global repositories into
+  `reference-docs/schemas/` with acknowledgements
+
 ## [0.1.1] - 2026-05-05
 
 - Simplify `Tbx::Namespaces::TbxNamespace` to `Tbx::Namespace`

 ### Key Implementation Patterns
@@ -105,6 +114,17 @@ end
 
 **Autoload Pattern**: Elements are autoloaded via `lib/tbx.rb`. When adding new elements, add autoloads in alphabetical order.
 
+**DataElement Concern** (`lib/tbx/data_element.rb`):
+- `Tbx::DataElement` — injects shared attributes (id, lang, target, datatype, type, content) via `self.included(base)` hook
+- `Tbx::DataElement::InlineContent` — adds inline child attributes (hi, ec, foreign, ph, sc) for elements with `entity.noteText` content
+- XML mappings remain explicit per class (lutaml-model's `xml do` uses `instance_eval` on a separate context)
+- Included by: Admin, Descrip, TermNote (with InlineContent); AdminNote, DescripNote, TransacNote, Transac, Ref (without)
+
+**Module TYPES/VALUES** (`lib/tbx/modules/`):
+- Each module defines `*_TYPES` and `*_VALUES` hashes keyed by Ruby symbol, valued by TBX string
+- Element classes compose TYPES via `merge` from all applicable modules (e.g., `TermNote::TYPES` merges Min + Basic + Linguist)
+- Source: Min.tbxmd, Basic.tbxmd, Linguist.tbxmd, TBXcoreStructV03.rng
+
 ### XML Namespace
 
 The TBX namespace is `urn:iso:std:iso:30042:ed-2` defined in `Tbx::Namespace`.
