Brief: R4, red suite on develop: 17 grammar and sysroot tests (fix forward)

Blocks: every push (the driver stopped: suite red after 2 QA rounds).

Problem

CI run 41408230519 on 07798a99 (ci/briefs), job arm64, cargo test -p nikaia --test it: 17 failed: build_time_dependencies::a_grammar_action_calls_a_dependency_at_build_time, …calls_another_file_of_its_package, dsl_grammar::{text_the_grammar_refuses_is_refused_at_the_block, a_block_over_a_grammar_is_its_entry_s_value, the_block_has_the_entry_s_type, two_blocks_in_one_statement_are_two_values}, grammar_at_build_time::* (6), language::the_build_time_package_passes_its_own_tests, project::a_grammar_at_build_time_reaches_a_project_build, sysroot::{stds_nikaia_half_lowers_the_same_at_both_switches, the_committed_rust_is_what_this_compiler_lowers, the_tools_lower_the_same_on_one_thread_as_on_every_core}. Suspects (unpushed local commits since origin/develop): 0489f495 (M2 grammar_run.nika, GrammarDriverHost), b285603c + 0016f6ef (M1 comptime_tree, comptime_run RefCell), and a committed lowered/*.rs or lowered.rs that does not match what the compiler lowers from the committed .nika (sysroot tests).

To build

  1. Work ONLY in the clean detached worktree /home/user/nikaia-red (it is at develop HEAD; the main checkout holds other agents’ half-done files and does not build). Use CARGO_TARGET_DIR=/home/user/Nikaia/target to share the dependency builds (disk is small). Reproduce one grammar test and one sysroot test, find the cause with git log origin/develop..HEAD, fix it forward as small commits there (never revert a whole move unless the fix is out of reach; then revert only the breaking commit and say so).
  2. Run all 17 tests green, plus cargo test -p nikaia --lib, cargo clippy --all-targets -- -D warnings, cargo fmt --check, and lower-std fixpoint if a tools/*.nika changed.
  3. Your commits are on a detached HEAD in that worktree: name every sha in the report; the supervisor cherry-picks them onto develop. Do not touch the main checkout /home/user/Nikaia except writing your report there.
