fmt for every form, parse tests (#984 steps 3, 5, 6)Score: the language topics (owner, 2026-11-03), #984 against ADR-async-5. Needs a1b on develop. Forms a1b refuses at parse (not built yet, until #986) are not formatted here. Rust is allowed where the code is Rust (#1214); fmt is tools/fmt.nika, written in Nikaia. Read docs/specification/adr/adr-async-5.md D5, D30, D33, and the NK21xx row of Part III first. S=1, C~2-3 M.
Owns:
crates/nikaia/src/parser/mod.rs and the check pass that raises NK2115 / NK2120 if it is not the parser, crates/nikaia-std/src/tools/fmt.nika and its lowered file, new tests tests/compiler/tests/async_parse_*.nika and tests/errors entries for the two codes.Not yours:
async before a function’s declaration, a let or a loop is NK2115 (D5); an async form inside a loop’s body is NK2120 (D30), with the help Part III names (xs.par_iter().for_each fn(x) { … }). Both codes are specified; register them where the codes table of the compiler lives if they are not there. Tests: a refusal for each, with its .stderr. Commit Part of #984.fmt and the parse tests (#984 steps 5, 6): nikaia fmt formats every form a1b parses, and formatting twice changes nothing. Tests: one formatter test over all forms (input, expected output, idempotent), plus parse tests for any form a1 left without one. Commit Part of #984; if #984 is then fully built (steps 1-6), the last commit says Fixes #984.List under Body: every Rust function you added or changed, for #557 / #125.
A form Nikaia, std or the toolchain lacks is sorted per CLAUDE.md A missing form stops the work. A further defect: no second fix in this brief, file nothing, report it under Found: with its probe.
Rs2nika: none.
Both steps hold with tests. nikaia test tests/compiler --both-settings and tests/errors give every count as before plus the new tests; the it tests filtered on fmt, async, spawn; the guard set of .claude/agents/builder.md. Clippy clean; the lower-std fixpoint holds. No changelog line.
a1’s nodes are missing; an existing program is refused by NK2115/NK2120 (name it under Found:).
