Score: self-hosting lane, goal of the day 90 %. crates/nikaia/src/parser/mod.rs parse_unrefined (:787-886, check the lines first; M7 left it unstarted) and what further of parser/mod.rs is logic rather than a thin host, into the tools/parse_*.nika file that holds its neighbours (where.nika finds it). Keep the public Rust entry points as thin forwards with unchanged signatures.

target/fast/nikaia run scripts/where.nika -- NAME and -- --outline FILE. Move the logic, keep in Rust only what must touch Rust-only types (the Parsed/Checked handles, anyhow, process spawning) as thin host methods or forwards with unchanged signatures, so no caller changes. Shape: faithful (same output, same order, same texts). Write a probe of a few lines with target/fast/nikaia run before each non-obvious form.Found: the gap with the probe and Needs: supervisor decision; never write around it. A compiler defect you can fix in one small commit with a tests/compiler test, fix; else stop that piece and report it.lower-std, only the lowered/*.rs of your own .nika files and lowered.rs lines for your new files are yours; never stage another agent’s file.
