Score: self-hosting lane, goal of the day 90 %. crates/nikaia/src/project.rs (3608 lines): impl Project (:1789-2285), lower_reading (:719-1230), explain (:1630-1788), run_tests (:2471-2596) into the project_*.nika files that hold their neighbours (project_lower.nika, project_tests.nika, project_check.nika; a new project_build.nika if none fits).

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. If lower-std fails in a file that is not yours, wait a few minutes and run it again; after three tries report Found:.Part: #125. Self-hosting share before and after in Body: (python3 scripts/self_hosting.py | tail -n 1, measuring only).docs/briefs/* but your report, the uncommitted files git status shows at start, sysroot.rs, modules.rs, contracts/keeps.rs, contracts/sync.rs, text_tiers*, bounds_report*, describe*, contracts/*, emit/*, parser/* (other lanes). The main checkout may not build while another agent is mid-edit (e.g. ledger_items): wait and retry, never fix their file.cargo test -p nikaia --lib project, cargo test -p nikaia --test it -- project::, cargo test -p nikaia --test it -- self_hosting:: and 40 tests/compiler tests with .stderr via target/fast/nikaia test (pick across NK codes).docs/builder-facts.md first. develop in the main checkout; other agents’ uncommitted files are not yours: never touch or stage them.target/fast/nikaia run scripts/commit.nika -- REPORT (it adds exactly the report’s Files:); the driver pushes.cargo build --profile fast -p nikaia, lower-std and its fixpoint when a tools/*.nika changed, cargo fmt, cargo clippy --all-targets -- -D warnings, scripts/pre-push-check.sh, the tests the brief names and the ones your change touches.CHANGELOG.md, badges and NK codes are the supervisor’s.

Anything after it reads as content.Deviation: only for a step of the brief built otherwise than written, or not built. Found: only for a defect outside your change.
