Subject: [PATCH] TIER-2 READ conductor/code_styleguides/error_handling.md
 end-to-end before Phase 9: re-read Helper/utility migration guidance (lines
 1000-1020 in plan.md), drain plane section, and Result-recovery pattern.
 Phase 9 covers helper/utility module-level sites; the audit shows 0
 INTERNAL_BROAD_CATCH sites in this category in src/gui_2.py. The one Phase 9
 site from the inventory (L1398 _close_vscode_diff) is actually
 INTERNAL_SILENT_SWALLOW (the bare-except classification), which is handled in
 Phase 10 (logging NOT a drain). Phase 9 has no sites to migrate in this
 track.
