Structured drafts (tools/draft_structure.py: if/else, loops, switch; goto kept only where irreducible, with the reason), jump tables as switch (x), tools/groundtruth.py (port vs draft: RAM variables and call-outs), tools/portstyle.py (10 mechanical style checks, report only), no-goto rule in CLAUDE.md rule 2. Reuses the user's CT tools.

Evidence: 9 field drafts US+JP gotos 170 -> 6 (all in UpdateObjFrame, commented), 65 jump-table routines draft and compile with -Werror (gotos 3 369 -> 885); draft_check title_to_mines_save + field_menu_tour US+JP 291 836 calls, 0 mismatch, 0 fallback; groundtruth 9/9 field ports match (battle/Rand: draft reads one extra byte, to check); portstyle 0 findings; debug and clang -LE slow 27/27.

Fixes #50
