feat(phase21.5): strlen FAST EXE + loop JSONFrag diagnostics
## Task A: emit v0 boxcall (bin version) ✅ - Fix: emit_mir_json_for_harness_bin now handles I::Call with Callee::Method - Added: Proper v0 boxcall emission when NYASH_MIR_UNIFIED_CALL=0 - Location: src/runner/mir_json_emit.rs:641-707 - Test: emit_boxcall_length_canary_vm.sh → PASS ## Task B: strlen FAST EXE (AOT without plugin) ✅ - Fix: FAST lowering now tracks newbox(StringBox) creation - Added: newbox_string_args fallback in boxcall.py (lines 133-143) - Added: StringBox tracking in newbox.py (lines 82-91) - Benefit: EXE can compute string.length() without StringBox plugin - Test: s3_backend_selector_crate_exe_strlen_fast_canary_vm.sh → PASS (rc=5) ## Task 1: selfhost-first Diagnostic Logging ✅ - Added: HAKO_SELFHOST_TRACE=1 outputs Program JSON stats - Added: HAKO_SELFHOST_NO_DELEGATE=1 shows detailed failure logs - Added: [builder/selfhost-first:fail:*] markers + last 80 lines - Location: tools/hakorune_emit_mir.sh:try_selfhost_builder() ## Task 2: loop JsonFrag Hit Rate Improvement ✅ - Added: FORCE=1 fallback for non-Lt comparison operators - Added: find_any_local_int_before() fallback when strict fails - Location: lang/src/mir/builder/internal/lower_loop_simple_box.hako - Benefit: Higher JSONFrag hit rate under HAKO_MIR_BUILDER_LOOP_FORCE_JSONFRAG=1 ## Task 3: crate EXE Failure Diagnostics ✅ - Added: LLVM IR dump on build failure (first 120 lines) - Added: Build error log capture (last 40 lines) - Location: tools/smokes/v2/profiles/quick/core/phase2100/stageb_loop_jsonfrag_crate_exe_canary_vm.sh ## Test Results - emit_boxcall_length: PASS ✅ - strlen_fast (FAST=1): PASS (rc=5) ✅ - loop_jsonfrag: SKIP (diagnostic enhanced) ⚠️ ## Implementation Principles - 既定挙動不変 (Default unchanged) - Dev toggle guarded (FAST=1, FORCE=1, TRACE=1, NO_DELEGATE=1) - Minimal diff, easy rollback - Clear failure diagnostics for future fixes 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
