概要

docs/architecture-p4.md を追加。P4 バックエンドの全体を 2 パイプライン + ステージ別 mermaid 図で詳細図解（ユーザー要望）。

内容

  • A. ビルド時（コード生成）: .ubnf → CodegenMain --generators Parser,AST,Mapper,Evaluator → TinyExpressionP4Parsers/P4AST/P4Mapper/P4Evaluator。各ジェネレータの役割表、@mapping/@declares/@scopeTree/@backref の意味、findCapturedToken/透過choice/assoc widening の要点。
  • B. 実行時（評価）: ソース → パース → マッピング → TinyExpressionP4AST → P4TypedAstEvaluator。AstEvaluatorCalculator の fallback チェーン、evalディスパッチ、if-source shadow、宣言/型推論経路（C）。
  • バックエンド一覧、主要クラス早見表。

7 つの mermaid 図（全体俯瞰 / codegen / 注釈 / fallback / parse→map / eval dispatch / 宣言経路）。GitHub 上でレンダリングされます。

ドキュメントのみ（コード変更なし）。関連: #32, #35, #22, #38, unlaxer-parser #40。

Add docs/architecture-p4.md: detailed, split-by-stage walkthrough of the two P4
pipelines with mermaid diagrams — build-time codegen (.ubnf → CodegenMain →
Parser/AST/Mapper/Evaluator) and runtime evaluation (source → parse → map →
TinyExpressionP4AST → P4TypedAstEvaluator, incl. the fallback chain, if-source
shadow, and the declaration/declared-type path). Plus a main-class cheat sheet.

概要
docs/architecture-p4.md を追加。P4 バックエンドの全体を 2 パイプライン + ステージ別 mermaid 図で詳細図解（ユーザー要望）。
内容
  • A. ビルド時（コード生成）: .ubnf → CodegenMain --generators Parser,AST,Mapper,Evaluator → TinyExpressionP4Parsers/P4AST/P4Mapper/P4Evaluator。各ジェネレータの役割表、@mapping/@declares/@scopeTree/@backref の意味、findCapturedToken/透過choice/assoc widening の要点。
  • B. 実行時（評価）: ソース → パース → マッピング → TinyExpressionP4AST → P4TypedAstEvaluator。AstEvaluatorCalculator の fallback チェーン、evalディスパッチ、if-source shadow、宣言/型推論経路（C）。
  • バックエンド一覧、主要クラス早見表。
7 つの mermaid 図（全体俯瞰 / codegen / 注釈 / fallback / parse→map / eval dispatch / 宣言経路）。GitHub 上でレンダリングされます。
ドキュメントのみ（コード変更なし）。関連: #32, #35, #22, #38, unlaxer-parser #40。

Add docs/architecture-p4.md: detailed, split-by-stage walkthrough of the two P4
pipelines with mermaid diagrams — build-time codegen (.ubnf → CodegenMain →
Parser/AST/Mapper/Evaluator) and runtime evaluation (source → parse → map →
TinyExpressionP4AST → P4TypedAstEvaluator, incl. the fallback chain, if-source
shadow, and the declaration/declared-type path). Plus a main-class cheat sheet.
