keeps::infer, the_impls_own and uses_of into keeps.nika (Part #125)Score: self-hosting lane, no plan row (K1-K3 moved the walk: keeps.nika has uses_in :63 and everything under it; lends.nika the fixpoint kept_by :154 and keeps_its :198). About 610 lines of Rust move, by hand.

crates/nikaia-std/src/tools/keeps.nika (pattern lends.nika; doc comments carried over): by_value, no_uses (:107-117); infer (:119-379) as pub fn keeps_infer[H: KeepsHost](mut ledger: Ledger, units: ref Vec[ParsedView], library: ref Ledger, resolved: ref collections::BTreeMap[String, CheckMethodCalls], host: ref H) -> KeepsColumn; Column, Keeper, ImplRow (:381-415) as KeepsColumn, KeepsKeeper (unit: i64), KeepsImplRow (a struct may hold method: ref Spanned[Item], as ParsedView does); the_impls_own (:417-542, the NK1264 finding is a CheckFinding with CheckSeverity); uses_of (:598-774) as pub fn keeps_uses_of(...); holds_either (:776-779). Everything they call is Nikaia already: ty.nika method_index :1992, tether.nika declare_unit / a_parse_that_views :74 / INPUT_POSITION :23 (Rust INPUT), views.nika fields_held :1802 and holds_view :412, declared.nika written_ty :23, lends.nika kept_by / keeps_its. parsed.text(sym) is view.text(sym), parsed.interner is view.words.pub trait KeepsHost with fn holes(ref self, unit: i64, expr: ref Expr) -> Vec[Expr] sync (Rust: crate::emit::literal_expressions(units[unit], expr), handed to uses_in as fn(e) { host.holes(unit, e) }) and fn keeping_statement(ref self, unit: i64, method: ref Spanned[Item], target: String, parameter: String, own_kept: ref collections::BTreeMap[String, collections::BTreeSet[String]], own: ref Ledger, library: ref Ledger) -> Span sync (Rust: the kept keeping_statement). The ledgers go as arguments, not in the host: keeps_infer holds ledger as mut.target/fast/nikaia run, both run with the right output): k4_infer.nika (a struct with a ref enum field in a Vec, a map keyed (String, String) read with [("T", "go")] ?? return, a nested BTreeMap[String, BTreeMap[String, Vec[K]]] grown by the add_kept pattern of lends.nika :182, a lambda capturing a fn parameter handed on as fn(ref E) -> Vec[E] sync) and k4_host.nika (a generic [H: Host] captured in such a lambda, a host method taking mut Vec). Write "T", not "T".to_string() (NK1301); print writes no newline.keeping_statement (:544-596, it clones the item and truncates its statements), taking method: &Spanned<Item>, target: &str in place of row and calling keeps_uses_of; the impl KeepsHost (holding units and the two method indexes); pub use of KeepsColumn as Column and KeepsKeeper as Keeper; and pub fn infer(ledger: &mut Ledger, units: &[&Parsed], library: &Ledger, resolved: &BTreeMap<String, crate::check::MethodCalls>) -> Column as a forward building the views with crate::check::parsed_view_of. Untouched callers: the 2 keeps::infer( calls in infer_package_noted (contracts/mod.rs:465, :476). Touched, because the lowered struct has no Default and unit is i64: contracts/sync.rs:182 (column: Default::default()) and modules.rs:405, :772, :784 (as usize / from without the cast).lower-std, only lowered/keeps.rs and lowered.rs are yours. lowered/emit_core_leaves.rs differs in the tree from another agent’s uncommitted emit_core_leaves.nika: neither stage nor restore it.docs/briefs/* but your report, the uncommitted files git status shows at start.lower-std and its fixpoint; nikaia.contracts / nikaia.derived of std byte-identical.
