/*
* test_edge_structural.c — Pipeline / edge-CREATION reproduction suite.
*
* ════════════════════════════════════════════════════════════════════
* PURPOSE
* ────────
* Comprehensively probe whether the GRAPH PIPELINE creates each non-import
* edge type for each hybrid-LSP language, with special emphasis on CROSS-FILE
* scenarios where the resolver must map a bare name in file B to a definition
* node living in file A.
*
* This is distinct from the extraction-level suites (test_extraction.c,
* test_extraction_inheritance.c, test_extraction_imports.c) which test whether
* cbm_extract_file() populates the right fields. Here we run the FULL
* production pipeline (index_repository via MCP) and assert the resulting
* graph DB contains the expected edges via cbm_store_count_edges_by_type.
*
* The companion file test_edge_imports.c (another workstream) covers IMPORTS
* edge creation. This file covers every OTHER edge type.
*
* ════════════════════════════════════════════════════════════════════
* EXPECTED GREEN vs RED — REASONING
* ──────────────────────────────────
*
* CALLS (cross-file):
* All 9 hybrid-LSP languages use the generic name-based resolver
* (pass_calls.c). The resolver populates the registry with all defs first,
* then matches call sites by name. Cross-file is structurally identical to
* same-file from the resolver's perspective (registry is project-wide).
* CALLS resolve at 99.6100% on real repos, so all 9 languages are expected
* GREEN. Any RED would be a real regression.
*
* INHERITS (cross-file class extends):
* Resolution requires: (a) base_classes extracted correctly at the
* extraction layer, AND (b) the registry resolving that bare name to the
* correct Class node in the other file. Known extraction bugs (documented
* in test_extraction_inheritance.c):
* Python — simple `class Dog(Animal):` broken; base_classes holds "(Animal)"
* with parens — extraction RED → INHERITS edge RED.
* TypeScript — extractor stores "extends" keyword not the type name → RED.
* PHP — base_classes never populated → RED.
* Kotlin — `:` supertype syntax not parsed → RED.
* Expected GREEN (extraction works):
* Java, C#, C++ — extraction correct per test_extraction_inheritance.c.
* Rust — uses impl_traits not base_classes; IMPLEMENTS path, not
* INHERITS. No INHERITS expected.
* Go — struct embedding / interface satisfaction uses IMPLEMENTS not
* INHERITS in the Go semantic pass.
*
* IMPLEMENTS (interface):
* Rust `impl Trait for Struct` cross-file: trait in a.rs, impl in b.rs.
* The resolve_impl_traits pass uses registry lookup for both trait_name and
* struct_name. If both are in the registry (from definitions pass), the edge
* is created. Expected GREEN when both files are indexed.
* Java `implements` interface (same-file): extraction stores base_classes; the
* semantic pass creates INHERITS for `extends` and IMPLEMENTS for interfaces
* (pass_parallel.c line ~1943). Expected GREEN same-file, RED cross-file
* until the resolver properly distinguishes Class vs Interface targets.
* Go implicit interface satisfaction: pass_semantic.c cbm_pipeline_implements_go()
* is triggered only when the struct's method-set fully covers the interface's.
* Expected GREEN when struct methods and interface are in same index.
* C# `class X : IFoo`: extraction stores base_classes; same INHERITS/IMPLEMENTS
* resolution path as Java. Same-file expected GREEN.
*
* DECORATES (cross-file decorator):
* Python: decorator resolved via import map + registry. Cross-file requires
* an IMPORTS edge resolution that in turn requires the decorator to be in the
* registry. Expected GREEN for same-file (existing P6 contract confirms this).
* Cross-file expected GREEN if relative import resolves (Python OK for
* relative imports per P3).
* TypeScript: TS decorator (class decorator). TS extraction captures
* decorators array. Expected GREEN same-file.
* Java annotations: Java extraction may not populate decorators[]. Expected
* RED (unconfirmed — annotated as uncertain).
* Kotlin annotations: Kotlin extraction status unclear → tentatively RED.
* C# attributes: C# extraction unclear → tentatively RED.
*
* USAGE (cross-file type usage):
* The USAGE pass (pass_usages.c) creates edges when a type/symbol reference
* (not a call) resolves in the registry. Expected GREEN for languages where
* usages are extracted (Python, Go, TS). Uncertain for Java/C#/Kotlin/PHP/Rust
* where USAGE extraction coverage is unclear.
*
* DATA_FLOWS:
* Created by pass_data_flows.c via Route intermediation (HTTP_CALLS + HANDLES
* on the same route path). Not per-language — fixture-driven. Existing P6
* contract covers same-file. This suite adds a cross-file variant.
*
* OVERRIDE (Go interface method):
* Created by pass_semantic.c when a Go struct satisfies an interface; each
* implementing method gets an OVERRIDE edge to the interface method. Expected
* GREEN for Go with a struct + interface pair in the same index.
*
* TESTS (function-level test->production function):
* pass_tests.c creates this. Existing P6 covers Go. This suite adds Python
* and TypeScript cross-file variants.
*
* ════════════════════════════════════════════════════════════════════
* SUITE STRUCTURE
* ───────────────
* Edge family Languages / cases Expected
* ─────────────────────────────────────────────────────────────────
* CALLS cross-file Go/C/C++/Rust/Python/ 9 GREEN
* TS/Java/Kotlin/C#
* INHERITS cross-file Java/C#/C++ 3 GREEN
* Python/TS/PHP/Kotlin 4 RED
* IMPLEMENTS cross-file Rust 1 GREEN
* IMPLEMENTS same-file interface Java/C#/Go 3 GREEN (uncertain)
* DECORATES same-file Python/TS 2 GREEN
* DECORATES cross-file Python 1 GREEN
* DECORATES annotations Java/Kotlin/C# 3 uncertain→RED
* USAGE cross-file Python/TS/Go 3 GREEN (uncertain)
* DATA_FLOWS cross-file Python 1 GREEN
* OVERRIDE (Go implicit iface) Go 1 GREEN
* TESTS cross-file Python/TypeScript 2 GREEN
*
* Total test functions: 24
*
* NOTE: "Do NOT register in test_main.c" — this suite is SEPARATE from the
* existing lang_contract suite. The SUITE(edge_structural) macro defines
* suite_edge_structural() which can be wired up independently.
