agda-algebras

Create a new Agda module in agda-algebras with the correct canonical path, literate .lagda.md structure, OPTIONS pragma, header, and documentation, ready to type-check. Use when adding a new module, especially the classical-structure modules in M3 (semigroups, groups, lattices, rings).

Port a frozen Legacy.Base module into the canonical Setoid/ tree — classify the module, build or extend its Setoid analog over setoid equality, and rewire imports off Legacy.Base. Use whenever a module in Setoid/, Examples/, or Exercises/ still imports Legacy.Base.* (including the remaining M2-8 import fixes), or when M9 calls for porting the Continuous/Complexity relations.

Type-check Agda modules in the agda-algebras repository after editing any .lagda.md file, and verify the change meets the library's corpus-quality bar. Use whenever Agda source has been added or modified and needs validation before commit.
