About 35,000 fixes ruff marks safe across 32 rules (UP006/UP045/UP007 modern annotations, UP032 f-strings, SIM114/SIM118, RET501, and friends), removal of the 1,296 typing imports the rewrite orphaned, and hand fixes for what the fixers could not see: five star-import freeloaders of typing names, two F823 late-import annotations, the /get/config/list introspection crash on types.UnionType, redundant function-local RoleMappings imports in ui_sso.py that shadowed the module-level name once the annotation lost its quotes, and one FURB168 tautology. B009/B010/PIE804/RUF019 are excluded on purpose: their safe fixes rewrite getattr/setattr/**-splat/key-in-dict escape hatches into forms basedpyright then rejects (283 new errors measured), so their budgets stay at base values. ruff-strict-budget.json drops by 39,579 this commit (39,968 across the branch) with 28 rules at an actual 0 and 9 more sharply down. type-discipline-budget.json ratchets LIT002/LIT006/LIT009 down; LIT001 moves to the now-honest total: the checker matches the spelling `set` but not the alias `Set`, so the 160 typing.Set annotations rewritten to set[...] were always mutable-set annotations and only now count.
