/*
 * repro_lsp_kt_php_rust.c — EXHAUSTIVE per-LSP-pass invariant suite for the
 * Kotlin, PHP and Rust hybrid LSPs
 *   (internal/cbm/lsp/kotlin_lsp.c, php_lsp.c, rust_lsp.c).
 *
 * MIRRORS repro_lsp_c_cpp.c exactly: same shared assert_lsp_strategy runner,
 * same two invariants per (lang,strategy) — (a) inv_count_calls_by_source
 * module_sourced == 0 and a callable-sourced CALLS edge exists, and (b)
 * inv_edge_has_strategy(store, project, "<strategy>"). One TEST per
 * (lang,strategy); SUITE(repro_lsp_kt_php_rust) at the bottom.
 *
 * WHAT THIS ASSERTS — the LSP RESOLUTION CONTRACT, one invariant per strategy.
 *   Each hybrid LSP resolves a call via a specific STRATEGY and tags the
 *   resulting CALLS edge in its properties_json with a literal strategy string.
 *   The minimal fixture exercises exactly one strategy, indexes it through the
 *   full production pipeline (language picked from the file extension: ".kt" →
 *   Kotlin, ".php" → PHP, ".rs" → Rust), and asserts:
 *     (a) callable-sourcing — the inner call is sourced at a Function/Method
 *         node, never at a Module/File node (the #554 attribution bug).
 *     (b) strategy-presence — some CALLS edge carries the strategy literal in
 *         its properties_json (inv_edge_has_strategy, substring match).
 *
 * STRATEGY-STRING NOTE — the assertion string is the ACTUAL literal each LSP
 *   emits (substring-matched by inv_edge_has_strategy), NOT a uniform
 *   "lsp_<name>" mould:
 *     - Kotlin emits "lsp_kt_*" (kt_emit_resolved, kotlin_lsp.c:299).
 *     - PHP emits mostly "php_*" plus "lsp_unresolved" (emit_resolved /
 *       emit_unresolved, php_lsp.c:1238/1251). The "php_*" literals are the
 *       real keys — the reference suite's "lsp_<strategy>" shorthand does not
 *       apply to PHP, so the assertions below use the php_* literals verbatim.
 *     - Rust emits "lsp_*" (rust_emit_resolved_call, rust_lsp.c).
 *
 * RED vs GREEN — STATUS BOARD, not a pass/fail gate (runs only under
 *   make test-repro / bug-repro.yml, never the branch-protection ci-ok gate):
 *     - GREEN = the strategy works end-to-end = a permanent regression guard.
 *     - RED   = the strategy is dropped, lands Module-sourced, or never reaches
 *               the graph. The TEST documents the exact gap for the fixer.
 *
 * RUST CROSS-LSP IS NOT WIRED (documented gap). src/pipeline/pass_lsp_cross.c
 *   has NO CBM_LANG_RUST case in either cbm_pxc_has_cross_lsp (lines 282-298)
 *   or the cbm_pxc_run_one dispatch (lines 372-407). Go/C/C++/Python/PHP/Java/
 *   Kotlin are wired; Rust is absent. So rust_lsp.c can EMIT every strategy
 *   below, but those resolved calls never reach pass_lsp_cross → never become
 *   tagged CALLS edges in the graph. Every Rust strategy test is therefore
 *   expected RED until rust_lsp.c is wired into the pipeline. We assert the
 *   CORRECT (resolved) outcome anyway, per the reproduce-first contract: the
 *   red test is the durable record of the gap and turns GREEN the moment Rust
 *   is wired and resolving correctly.
 *
 * SKIPPED STRATEGIES (documented, not tested):
 *   Kotlin:
 *     - lsp_kt_safe   — listed in the kotlin_lsp.c header comment (line 32) but
 *                       NEVER emitted: grep for the literal finds only the
 *                       header. A `obj?.foo()` safe call routes through the
 *                       generic navigation handler and emits "lsp_kt_method"
 *                       (kt_eval_navigation_expression_type does not branch on
 *                       `?.` vs `.`). No fixture can produce "lsp_kt_safe".
 *     - lsp_kt_import — likewise header-only (line 34), never emitted. Import
 *                       targets surface through the top-level / method paths.
 *   Rust:
 *     - lsp_mod_decl  — emitted (rust_lsp.c:4347) but DELIBERATELY Module-
 *                       sourced: it temporarily sets enclosing_func_qn =
 *                       module_qn so the edge is attributed to the file's
 *                       synthetic module scope (a `mod foo;` declaration has no
 *                       enclosing callable). It would violate invariant (a)
 *                       (module_sourced == 0) by construction, so the shared
 *                       runner cannot express it. Also blocked by the unwired-
 *                       Rust gap above.
 *     - lsp_deref_dispatch / lsp_bound_dispatch / lsp_prelude_trait /
 *       lsp_short_name_unique / lsp_trait_ufcs_amb — emitted on harder-to-
 *       fixture paths (Deref chains, type-param bounds, prelude best-effort,
 *       crate-prefix short-name scan, multi-impl ambiguity). They are all also
 *       blocked by the unwired-Rust gap, so adding fragile fixtures for them
 *       buys nothing over the representative dispatch tests below; skipped.
