modules.rs into Nikaia (Part #125)Score: self-hosting lane (docs/priorities.md, owner’s direction 2026-10-27: moves first; modules.rs after M1, 1,239 lines). Plan row M2 (docs/selfhosting-plan.md, Large files 2). S=2 (~205 Rust lines, draft 36%), C~3-5 M (comparable: M1, 3136e7b). M1 is built (3136e7b).
modules.rs: test_function, is_a_test_function, with_tests_as_functions, names_in into crates/nikaia-std/src/tools/modules.nika (test_dispatcher, test_function :474 are there already: the Rust test_function is a duplicate to delete). Host added: parse_to_ast(text) -> Parsed for the entry re-parsed with its dispatcher; Nikaia rewrites Item::Test into Item::Fn over mut Vec[Spanned[Item]] and takes emit_walk::visited_in_* for names_in.crates/nikaia/src/modules.rs: test_function :578, is_a_test_function :585, with_tests_as_functions :1030-1146, names_in :1157-1230. Re-grep before cutting.__nikaia_test_K interned from Nikaia; today parser::parse_expression(&interner, &test_function(k))) is settled: a tools file interns through a callback intern: fn(ref String) -> winnow_grammar::Symbol sync, as check_walked_kept_call (check_walked.nika :101) and CheckHost::intern (check_host.nika :70) do. Use that callback (Rust passes |t| interner.intern(t) or the equivalent the interner offers), not parse_expression, for main and the test names; parse_to_ast stays the one Rust callback for the re-parse.Unit, Program, TestCase (Rust structs: Unit holds Parsed); the loop over units may stay Rust if it needs &mut Unit; then Nikaia does the per-file work (the Item::Test to Item::Fn rewrite of one file’s items, returning the titles and lines; the dispatcher text; names_in over one Parsed’s items). That cut is yours: name it in Body:.Rs2nika: costs are read by the converter lane: do not change crates/rs2nika/.rs2nika --profile check --file), report --score under Rs2nika:. Move the listed functions into modules.nika (prefix new public names modules_ where where.nika finds a clash) with their doc comments; modules.rs calls the lowered functions; the moved Rust is deleted. lower-std: only modules’ lowered file and its index lines change.Tests:.A lowering defect met is fixed in the compiler as its own commit with a test (Fix, do not work around, CLAUDE.md); if it is more than one step, stop and report it under Needs:. Known open checker defect, not yours: #909.
nikaia test tests/compiler --both-settings (every test block of it goes through this code); it tests filtered on test_ dispatch names_in permission package plus the guard set of .claude/agents/builder.md; clippy clean; lower-std fixpoint. Commit modules: tests as functions into Nikaia (M2), Part: #125. Changelog: none (a move).
An open design choice beyond the cut left above; a .stderr that would change; an error in another agent’s file.
