### Step 455: Behavioral Equivalence Checking
|
||||
**Status:** PASS (12/12 tests)
|
||||
|
||||
Implements behavioral-equivalence assertion generation with contract annotation
|
||||
grading from confidence scores (verified/likely/unverified+review).
|
||||
|
||||
**Files added:**
|
||||
- `editor/src/BehavioralEquivalence.h` — equivalence checker:
|
||||
- `EquivalenceAssertion`, `BehavioralCheckResult`, `BehavioralChecker`
|
||||
- inferred input generation for sort/search/sum/generic functions
|
||||
- inferred expected-output stubs for common patterns
|
||||
- confidence scoring heuristics from target translation shape
|
||||
- contract annotation assignment:
|
||||
- `@Contract(verified)` (>=0.90)
|
||||
- `@Contract(likely)` (>=0.70)
|
||||
- `@Contract(unverified), @Review(required,human)` (<0.70)
|
||||
- `editor/tests/step455_test.cpp` — 12 tests covering:
|
||||
- input inference for sort/search/sum/generic categories
|
||||
- custom input override behavior
|
||||
- confidence-tiered contract annotation mapping
|
||||
- same-language high-confidence default behavior
|
||||
- assertion metadata (`sameErrors`, `allPassing`) expectations
|
||||
- `editor/CMakeLists.txt` — `step455_test` target
|
||||
|
||||
**Verification run:**
|
||||
- `cmake --build editor/build-native --target step455_test` — PASS
|
||||
- `./editor/build-native/step455_test` — PASS (12/12)

- `./editor/build-native/step454_test` — PASS (8/8) regression coverage
