Phase 269 P1.0: Pattern8 SSA correctness - Add PHI node for loop variable `i` in pattern8_scan_bool_predicate.rs - Ensure proper SSA form: i_current = phi [(preheader, i_init), (step, i_next)] - Create loop_predicate_scan.rs for Pattern8 Frag emission - Pre-allocate PHI destination before block generation - Use insert_phi_at_head_spanned() for span synchronization Phase 269 P1.1: call_method return type SSOT propagation - Add callee_sig_name() helper in annotation.rs for function name formatting - Annotate call_method return types in emit_unified_call_impl() - Use module signature as SSOT for return type resolution (no hardcoding) - Arity-aware function name: "BoxName.method/arity" Fixes: is_integer() now correctly returns Bool instead of String Test: Simple call_method test returns exit=7 (loop test has pre-existing bug) Unit tests: All 1389 tests passing 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
