Sub-track 1 of the 5-sub-track result_migration_20260616 campaign.
Audit-driven research task: classify 43 ambiguous exception-handling sites
(24 UNCLEAR + 19 INTERNAL_RETHROW across 11 files) and update the
audit script's heuristics. No production code change.
Scope: 11 files, 43 sites, T-shirt S. The per-site decisions feed
sub-tracks 2-4 (small_files, app_controller, gui_2) as their starting
migration scope.
Files: spec.md, plan.md, metadata.json, state.toml under
conductor/tracks/result_migration_review_pass_20260617/. Row added
to conductor/tracks.md.
