-## CONVENTIONS
+- `test_cases/korean/rule_{N}.json` — 한글 점자 제N항
+- `test_cases/korean/rule_{N}_b1.json` — 제N항 붙임 1
+- `test_cases/math/math_{N}.json` — 수학 점자 제N항
+- 근거: `docs/2024 개정 한국 점자 규정.pdf`
 
-### Rust
+### 엔트리 형식
 
-- Edition 2024, resolver 3
-- PHF macros for static lookup tables
-- `Result<T, String>` for encoding errors (no custom error type)
-- Feature flags: `cli` (default), `wasm`
-- Tests inline with `#[cfg(test)]` modules
+```json
+{
+  "input": "입력 텍스트 (묵자 또는 LaTeX)",
+  "note": "설명 (선택, 동일 input이 여럿이거나 맥락 필요 시에만)",
+  "internal": "점자 내부표기",
+  "expected": "브라유셀 인덱스 연결 문자열",
+  "unicode": "점자 유니코드 문자열"
+}
+```
 
-### TypeScript
+### internal → expected/unicode 변환
 
-- `strict: true`, `moduleResolution: bundler`
-- `@/*` path alias to `./src/*`
-- ESLint: `eslint-plugin-devup` recommended config
-- Bun test with a preload plugin for WASM tests
+`braillove-case-collector/converter.py`의 패턴을 따른다:
 
-### Python
+```
+pattern: " a1b'k2l@cif/msp"e3h9o6r^djg>ntq,*5<-u8v.%[$+x!&;:4\0z7(_?w]#y)="
+braille: ⠀⠁⠂⠃⠄⠅⠆⠇⠈⠉⠊⠋⠌⠍⠎⠏⠐⠑⠒⠓⠔⠕⠖⠗⠘⠙⠚⠛⠜⠝⠞⠟⠠⠡⠢⠣⠤⠥⠦⠧⠨⠩⠪⠫⠬⠭⠮⠯⠰⠱⠲⠳⠴⠵⠶⠷⠸⠹⠺⠻⠼⠽⠾⠿
+```
 
-- Requires Python >= 3.13 (workspace), >= 3.8 (package)
-- `uv` for workspace management
-- `maturin` for building wheels
-- CLI entry: `braillify = "braillify:cli"`
+특수 매핑: `` ` ``→0, `{`→42, `}`→59, `~`→24, `|`→51
 
-## ANTI-PATTERNS (THIS PROJECT)
+`expected`는 각 문자의 인덱스를 문자열로 이어붙인 것, `unicode`는 대응하는 점자 유니코드 문자를 이어붙인 것이다.
 
-- **Never suppress encoding errors** - propagate `Result<T, String>`
-- **Never modify CSV test files without running full test suite** - `rule_map.json` must match
-- **Avoid `as any` or `@ts-ignore`** in TypeScript
+### 무결성 검증
 
-## COMMANDS
+`test_cases/testcase-integrity.test.ts`가 모든 엔트리의 internal → expected/unicode 일치를 검증한다. 대문자(수학 변수 A, B 등)를 포함한 internal은 기본 패턴 외이므로 skip된다.
 
-```bash
-# Install dependencies (runs uv sync, wasm-pack install, maturin install)
-bun install
+### 테스트 케이스 작성 원칙
 
-# Build all packages
-bun run build
+1. **PDF가 유일한 근거** — `docs/2024 개정 한국 점자 규정.pdf`에 없는 예제를 만들지 않는다.
+2. **PDF 순서 준수** — 기호 정의 → 해당 예제 순서로, PDF에 나온 순서 그대로 배치한다.
+3. **기호 단독 엔트리 필수** — 각 기호는 단독 엔트리로 먼저 등록하고, 그 뒤에 해당 기호를 사용하는 예제가 온다.
+4. **note는 필요할 때만** — 동일 input이 다른 의미로 쓰일 때, 또는 맥락이 필요할 때만 추가한다. input을 반복하는 note는 쓰지 않는다.
+5. **소속 정확히** — 각 엔트리는 해당 항 파일에만 존재한다. 다른 항의 예제를 섞지 않는다.
 
-# Run all tests (Rust coverage + Bun test + Pytest)
-bun run test
+### LaTeX 입력
 
-# Build landing site (requires test_status.json from test run)
-bun run build:landing
+수학 수식은 LaTeX 형식의 input도 테스트한다. 기존 엔트리의 LaTeX 버전을 추가하는 방식이다:
 
-# Dev server for landing
-bun -F landing dev
+- 형식: `$<LaTeX 수식>$` (앞에 `$`, 뒤에 `$`)
+- 동일한 `internal`/`expected`/`unicode`를 공유
+- `"note": "LaTeX"` 표기
+- **기존 예제의 변환만** — 새로운 수식을 만들지 않는다
 
-# Lint
-bun run lint
-bun run lint:fix
+```json
+{
+  "input": "$\\frac{3}{4}$",
+  "note": "LaTeX",
+  "internal": "#d/#c",
+  "expected": "6025129",
+  "unicode": "⠼⠙⠌⠉"
+}
 ```
 
-## NOTES
+주요 LaTeX 변환:
+
+| 수식 | LaTeX |
+|------|-------|
+| 분수 | `$\frac{분자}{분모}$` |
+| 근호 | `$\sqrt{x}$`, `$\sqrt[n]{x}$` |
+| 위첨자 | `$x^{2}$` |
+| 아래첨자 | `$x_{n}$` |
+| 부등호 | `$\neq$`, `$\geq$`, `$\leq$` |
+| 절댓값 | `$\|x\|$` |
+| 무한대 | `$\infty$` |
+| 적분 | `$\int f(x)dx$` |
+| 집합 | `$\cup$`, `$\cap$`, `$\subset$`, `$\emptyset$` |
+| 논리 | `$\land$`, `$\lor$`, `$\forall$`, `$\exists$` |
+
+### 대문자 수학 변수
 
-- **Test output**: `cargo test test_by_testcase` generates `test_status.json` for landing page
-- **WASM build**: `wasm-pack build --target bundler` in `packages/node`
-- **Python wheel**: `maturin build --release` in `packages/python`
-- **No CI workflows checked in** - build/test orchestrated via root `package.json`
-- **Korean comments** in Rust code reference specific rule numbers (e.g., "제14항")
+수학 점자에서 대문자 변수(A, B, N 등)를 사용하는 internal은 기본 64셀 패턴에 포함되지 않는다. 이런 엔트리는 `expected`/`unicode`가 빈 문자열이며, 무결성 테스트에서 자동으로 skip된다.

+## RULE ARCHITECTURE
+
+### Two parallel rule systems
+
+| System | Trait | Engine | Operates On | Used By |
+|--------|-------|--------|-------------|---------|
+| Korean (char-level) | `BrailleRule` | `RuleEngine` | Individual characters (`CharType`) | Korean text encoding |
+| Math (token-level) | `MathTokenRule` | `MathTokenEngine` | Token sequences (`MathToken`) | Math expression encoding |
+
+### BrailleRule (Korean, character-level)
+
+```rust
+trait BrailleRule: Send + Sync {
+    fn meta(&self) -> &'static RuleMeta;
+    fn phase(&self) -> Phase;           // Preprocessing → CoreEncoding → InterCharacter
+    fn matches(&self, ctx: &RuleContext) -> bool;
+    fn apply(&self, ctx: &mut RuleContext) -> Result<RuleResult, String>;
+}
+```
+
+Registered in `encoder.rs` → processes one character at a time via `RuleContext`.
+
+### MathTokenRule (Math, token-level)
+
+```rust
+trait MathTokenRule: Send + Sync {
+    fn name(&self) -> &'static str;
+    fn priority(&self) -> u16;          // Lower = runs first (10=lookahead, 50=core, 100=symbol)
+    fn matches(&self, tokens: &[MathToken], index: usize, state: &MathEncodeState) -> bool;
+    fn apply(&self, tokens: &[MathToken], index: usize, result: &mut Vec<u8>,
+             state: &mut MathEncodeState, engine: &MathTokenEngine) -> Result<MathTokenResult, String>;
+}
+```
+
+Registered in `encoder.rs::build_math_engine()` → processes parsed MathToken sequences with lookahead.
+
+### Math rule structs (in respective rule files)
+
+| Priority | Struct | File | Handles |
+|----------|--------|------|---------|
+| 10 | `FractionReversalRule` | rule_7.rs | Denominator-first simple fractions |
+| 10 | `ConditionalProbFractionRule` | rule_7.rs | =a/b with \| pattern |
+| 10 | `CombinatoricsRule` | rule_12.rs | nPr, nCr |
+| 50 | `NumberRule` | rule_1.rs | Number tokens |
+| 50 | `VariableRule` | rule_12.rs | Lowercase variables |
+| 50 | `UpperVariableRule` | rule_12.rs | Uppercase variables |
+| 50 | `OperatorRule` | rule_2.rs | Arithmetic operators |
+| 50 | `FunctionNameRule` | rule_47.rs | log, lim, sin, cos... |
+| 50 | `BracketRule` | rule_6.rs | Open/close parentheses |
+| 50 | `SuperscriptRule` | rule_18.rs | Superscript content |
+| 50 | `SubscriptRule` | rule_19.rs | Subscript content |
+| 50 | `DecimalPointRule` | rule_8.rs | Decimal points |
+| 50 | `PrimeRule` | rule_53.rs | Prime marks |
+| 100 | `MathSymbolRule` | encoder.rs | All math symbols (30+ dispatch chain) |
+

-## RULE IMPLEMENTATION
+## MATH RULES (src/rules/math/)
 
-Korean comments reference rule numbers from 2024 Korean Braille Standard:
+66 rule files (`rule_1.rs` through `rule_66.rs`) matching articles from the 2024 Korean Braille Standard math section (pages 51-84). Each file contains:
 
-- `제8항` - Standalone jamo
-- `제11항` - Vowel + 예 separator
-- `제14항` - 나/다/마... + vowel (no abbreviation)
-- `제28항` - Uppercase handling
-- `제31항` - Roman letter indicators
-- `제40항` - Number prefix
-- `제43항` - Numbers with punctuation
-- `제44항` - Number + Korean spacing
+- `is_xxx()` detection functions (used in MathSymbolRule dispatch chain)
+- `encode_xxx()` encoding functions (produce braille byte sequences)
+- MathTokenRule struct implementations (where applicable)
+- `#[cfg(test)] mod tests` with unit tests
+
+Infrastructure:
+- `encoder.rs` — `encode_math_expression()`, `build_math_engine()`, `MathSymbolRule`
+- `parser.rs` — `parse_math_expression()` → `Vec<MathToken>`
+- `function.rs` — Function name detection (sin, cos, log, etc.)
+- `math_token_rule.rs` — `MathTokenRule` trait, `MathTokenEngine`, `MathEncodeState`
 
 ## CONVENTIONS
 
 - PHF macros (`phf_map!`) for all static lookup tables
-- Error handling via `Result<T, String>` - propagate, never suppress
+- Error handling via `Result<T, String>` — propagate, never suppress
 - Feature flags: `cli` (default), `wasm`
 - Tests inline with `#[cfg(test)]` in each module
+- No `#[allow(dead_code)]` — all functions must be used or tested
+- Math rules: one `.rs` file per standard article (제N항)
 
 ## ANTI-PATTERNS
 
-- **Never use `unwrap()` on user input** - return `Err(String)`
-- **Never hardcode Braille dots** - use constants or PHF tables
-- **Never modify shortcut tables** without updating test CSVs
+- **Never use `unwrap()` on user input** — return `Err(String)`
+- **Never hardcode Braille dots** — use constants or PHF tables
+- **Never modify shortcut tables** without updating test cases
+- **Never add `#[allow(dead_code)]`** — wire functions into encoder or tests instead
+- **Never suppress type errors** — no `as any` equivalents
 
 ## TESTING
 
 ```bash
-# Run all tests with coverage
-cargo tarpaulin -p braillify
-
-# Run specific test
-cargo test test_encode
-
-# Generate test_status.json for landing page
-cargo test test_by_testcase
+cargo test                           # All tests (353+)
+cargo test test_by_testcase          # Testcase suite (2064 cases, tracks KNOWN_FAILURES)
+cargo test test_accuracy_report      # Accuracy report (raw encode, no test routing)
+cargo test test_no_regression        # Regression guard
+cargo fmt && cargo clippy            # Format + lint
 ```
 
-Tests read from `../../test_cases/*.csv` - format: `input,internal_repr,expected,unicode`
+Test cases in `test_cases/korean/*.json` and `test_cases/math/*.json`.
+
+Current status: 1710/2064 passing (354 known failures).
