The old character.md body parsing made the DM do mental arithmetic on every modifier, which is how my silver ended up at -20. This replaces it with a structured character.yaml, a small computation engine for derived values (skills, saves, passive perception, with breakdowns), and a set of bookkeeping tools that prevent arithmetic errors without enforcing 5e rules. The DM is still in charge of adjudication. Splits per-player files into character.yaml (structured), character.md (prose backstory and aliases), and notes.md (appending journal). Magic items become world entities with wikilinks from the character. Generic resource pools handle hit dice, charges, and class features through one mechanism. Adds 16 new character tools (damage, heal, add_effect, add_condition, add_item, set_item_status, use_resource, rest, etc.), all with deferred TUI notifications so the player sees the actual arguments. Damage and heal route to either the initiative tracker or the character sheet depending on whether a target is given, and the initiative versions sync back to the character sheet for player combatants. Also fixes two bugs the rewrite surfaced: _sync_player_hp was writing to the old flat hp.current path, and a test was passing the same stale path to update_character. Both have regression tests now. This is pretty solid!!!!
