# Step 11: Source Target Resolver
## 담당 역할과 필수 스킬
- 담당 역할: `implementation-agent`
- 필수 스킬: `harness`, `fesa-cpp-msvc-tdd`
- 이 Step만 `RED -> observed failure -> minimal GREEN -> focused/full VERIFY`로 수행한다.

## 작업
Requirement `R-DUP-002`의 ASCII/source-target owner를 구현한다.
1. `/tests/unit/core/ascii_test.cpp`
`/tests/unit/model/source_target_resolver_test.cpp`를 먼저 추가한다.
2. `C-DUP-004` tests cover ASCII-only lower/equality, positive source-label parsing,
separate node/element set namespaces, instance identity, declaration-order expansion,
duplicate/missing/ambiguous/nonpositive rejection and deterministic diagnostic order.
3. Missing headers/symbols로 RED compile failure를 기록한다.
4. Create `/include/fesa/core/ascii.h`, `/src/fesa/core/ascii.cpp`,
`/include/fesa/model/source_target_resolver.h`, and
`/src/fesa/model/source_target_resolver.cpp`; register both sources and both tests in CMake.
5. Candidate core functions:
```cpp
char AsciiLower(char value) noexcept;
bool AsciiCaseInsensitiveEquals(std::string_view lhs,
std::string_view rhs) noexcept;
Result<std::int64_t> ParsePositiveSourceLabel(std::string_view text);
```
6. Candidate model interface:
```cpp
enum class SourceEntityKind { kNode, kElement };
struct SourceTargetIndexEntry {
SourceEntityKind entity_kind;
std::string instance_name;
std::string target_name;
SourceEntityId source_id;
EntityIndex entity_index;
std::size_t declaration_order;
};
class SourceTargetIndex {
public:
explicit SourceTargetIndex(std::vector<SourceTargetIndexEntry> entries);
const std::vector<SourceTargetIndexEntry>& Entries() const noexcept;
};
struct SourceTargetQuery {
SourceEntityKind entity_kind;
std::string instance_name;
std::string target_name_or_label;
};
struct ResolvedSourceTarget {
SourceEntityId source_id;
EntityIndex entity_index;
};
class SourceTargetResolver {
public:
explicit SourceTargetResolver(const SourceTargetIndex& index) noexcept;
Result<std::vector<ResolvedSourceTarget>> Resolve(
const SourceTargetQuery& query) const;
};
```
7. `SourceTargetIndex` is an immutable index built from validated candidate or Domain semantic
records. It owns its compact entries; the resolver stores a non-owning reference, so the index
lifetime must outlive the resolver and Doxygen must state it.
8. Replace repeated `AsciiLower`, equal-name, positive-integer, and same-meaning source resolution
helpers only. Preserve each owner-specific diagnostic category/source location.
## Acceptance Criteria
```powershell
cmake --build .harness/build --config Debug --target fesa_unit_tests
ctest --test-dir .harness/build -C Debug `
-R "Ascii|SourceTargetResolver|InpDomainMapping|DofManager|LoadAssembly|ResultRecovery" `
--output-on-failure
rg -n "AsciiLower|EqualName|TryPositiveInteger" src/fesa
& "C:/Program Files/LLVM/bin/clang-format.exe" --dry-run --Werror `
include/fesa/core/ascii.h src/fesa/core/ascii.cpp `
include/fesa/model/source_target_resolver.h `
src/fesa/model/source_target_resolver.cpp `
tests/unit/core/ascii_test.cpp `
tests/unit/model/source_target_resolver_test.cpp
cmake --build .harness/build --config Debug
ctest --test-dir .harness/build -C Debug --show-only=json-v1
ctest --test-dir .harness/build -C Debug --output-on-failure
```
The helper scan may show only the shared definitions and intentional calls, not repeated local
definitions. Full diagnostics and stable order tests must pass.
## 검증 및 상태 갱신
- RED, focused resolution cases, duplicate scan and full CTest를 summary에 기록한다.
- Identity/diagnostic order regression이면 `error`; missing upstream identity contract이면
`blocked`로 기록한다.
- 성공 시 현재 Step만 `completed`로 갱신한다.
- timestamp, retry, commit, advancement는 Executor 소유다.
## 금지사항
- Unicode case folding이나 locale behavior를 추가하지 마라. 이유: input contract is ASCII.
- Node와 element set namespace를 합치지 마라.
- Domain mapper를 responsibility files로 split하지 마라. 이유: Step 21 소유다.
- 직접 commit하거나 hook script를 수동 실행하지 마라.
