text(..)Score: a defect of a decided form (owner, 2026-10-30: bindings inside text(..) are supported), found by this lane (y12); nothing in packages/yaml needs it today, it closes #1013. Runs after y2c-properties.md (run 3), which waits on y15-1015-fmt-guard-label.md.
Decided (owner, 2026-10-30): s:text(parts:Part*) binds s to the text text(..) covered (a view) and parts as it would be bound without the text(..) around it, in one pass over the input. Steps 1-3 are built (bdbe8a7a: bindings inside text(..) read by the action; 627af41e: hygienic type parameters). Since #1033 (y12, 6e843b68) a guard reads the text(..) label itself.
Step 4: a name bound inside text(..) is in scope for what follows in the sequence, a guard included. Today this is refused:
grammar G {
rule Ch -> i64 = x:any if(x >= '0' && x <= '9') -> { 1 }
entry rule plain -> String = s:text(d:Ch+) if(d.len() > 1) ";" -> { s }
}
fn main() {
let r = G::plain("12;")
println(r)
}The architect ran it on today’s develop: NK1117 “d isn’t declared anywhere” at 3:45 (the guard). The action may read d (step 1), so the guard must too.
grammar_values in crates/nikaia-std/src/tools/check_grammar.nika:310: Pattern::Bind { name, pat } (line 318) walks pat with a cloned scope and pushes only the label; the text(..) call is Pattern::Call (line 371, grammar_call), whose inner bindings stay inside. The fix: what a text(..) call’s argument binds flows out to the sequence’s followers, inside a Bind too (as a Seq hands its bindings on).d before the guard (the helper rule __nikaia_covered and the prelude in crates/nikaia-std/src/tools/emit_grammar.nika / emit_pattern.nika), and y11 walks a guard’s condition in bind_grammar_pattern (crates/nikaia-std/src/tools/text_tiers.nika) after the labels before it. If rustc or the tier pass refuses after the checker fix, those are the files; stop and report if it needs more than them.tests/compiler/tests/grammar_a_guard_reads_a_binding_text_label.nika (y12) and the step-1 test of bdbe8a7a (git show --stat bdbe8a7a)..nika under crates/nikaia-std/src/tools/ has its lowered twin in tools/lowered/: nikaia lower-std, commit both.Read docs/builder-facts.md (its first trap: the winnow-grammar rev of target/fast/nikaia).
tests/compiler/tests/grammar_a_guard_reads_a_name_bound_inside_text.nika + .stdout: the probe’s grammar, G::plain("12;") prints 12, and G::plain("1;") with a catch that prints error (the guard fails); it fails on the unfixed binary (NK1117, say so under Tests:). Part II 10’s sentence on bindings inside text(..) (added with step 1, find it with grep -n "text(" docs/specification/20-nikaia-advance.md) gets “a guard after it reads them too” if it does not say so already.The new test passes; NIKAIA_CACHE_LIMIT=2G target/fast/nikaia test --project tests/compiler > out.txt 2>&1 green with the grammar_ tests in it; the package gate below green; committed and pushed with Fixes #1013. Files you may change: the files named above with their lowered twins, the Part II sentence, the new test. Name under Changelog: what the change decided.
docs/builder-facts.md first. develop in the main checkout; git status at start: other agents’ uncommitted files are not yours, never touch or stage them.git add <files> only; commit after each step; git push origin develop fast-forward, no rebase (rejected: report Pushed: rejected, go on committing).cargo fmt, cargo clippy --all-targets -- -D warnings, scripts/pre-push-check.sh, and the gate of .claude/agents/builder.md (#852).CHANGELOG.md, badges; no new NK code. New tests in Nikaia only; never the full suite. No foreground sleep, no polling; scripts in files.std or the toolchain lacks stops the work: no code around it unless an ADR or Part I-III refuses it (name it). Else Result: blocked, Found: gap + probe, Needs: owner decision (CLAUDE.md, A missing form stops the work).NIKAIA_CACHE_LIMIT=2G; at most two clones with target/ in the machine; delete your own clone’s target/ and target/release/nikaia-scratch at the end; report GB freed.Pushed: line names the pushed sha. A report without a Pushed: line, or with a placeholder left in (TC, DISK), is not done and cuts the batch (k3a1 2026-10-29: Result: done, nothing committed).NIKAIA_CACHE_LIMIT=2G target/fast/nikaia test --project packages/yaml green, and cargo test --profile fast -p nikaia --test it -- fmt::every_nika_file (it formats every .nika under packages/). For a change only under packages/yaml/ this is the gate the line above asks for; a change under crates/ runs the gate of .claude/agents/builder.md (#852) as well. target/fast/nikaia is built by the session hook; if it is missing, cargo build --profile fast -p nikaia once.Changelog: none, unless the brief changes crates/.Files not to touch: anything outside packages/yaml/ and the brief’s own report, unless the brief names it; never docs/briefs/batch.txt or a brief of another lane.
max_turns: commit and push every finished step, then report Result: partial with what is left under Needs:. Uncommitted work at the end is lost work (y4 ran out at 110)./home/user/Nikaia/docs/briefs/yaml/y14-1013-guard-inner-label.md.report.md)Fields of docs/architect.md, Briefs and reports: Result: done|noop|partial|blocked (the bare word alone on that line: Result: done, never a summary after it, which cuts the batch, b869a 2026-10-27; Owner: is a question for the owner or none, never a role), Files, Commit, Body (optional, one paragraph for the commit message), Fixes, Pushed, Tests, Gate (green|red), Deviation, Found, Needs, Changelog, Owner, Disk freed, and for a move Rs2nika: (the kept N of M lines of rs2nika --score, then the three costliest hand edits; none for a task that moves no Rust, none (redesign) for a brief with Shape: redesign and no Convert: line). none where nothing, and then the bare word: Deviation: none (a note) cuts the batch (batch.nika compares exactly); a note goes into the commit message. Found: is only for a defect outside your change (it cuts the batch); a process event such as another session resetting or rewriting your files is no Found:, it goes under Needs: (m3a 2026-10-28); a converter draft that came out wrong is no Found:, it is one of the costliest edits under Rs2nika:, which the converter lane reads (e12-4b 2026-10-27); how you solved your own step goes into the commit message. Deviation: is only a step of the brief built otherwise than written or not built (a choice the brief left to you, such as keep what X needs and say so, is no deviation: it goes into the commit message; nor is building two steps in one commit when every step is built, e12-3a 2026-10-27, nor a step another commit on develop already built, shown by your test failing with that commit’s change reverted, b889 2026-10-27: name the commit in Body:, nor a test’s expected .stdout/.stderr taken from what the program really prints where the brief’s sketch of it was short or wrong, b934 2026-10-29: say so in Body:, nor a lowering that follows the ADR governing it where the brief’s expected lowering contradicts that ADR, b933 2026-10-29: name the ADR in Body:, nor a lowering other than the brief’s where rustc cannot take the brief’s, b1029 2026-10-31: say why in Body:, nor re-keying an allow-list entry (KNOWN) whose hash changed for the same program and the same reason, b-fixforward-sweep2 2026-10-28: say so in Body:, nor an existing test’s expected .stdout/.stderr updated because your change rightly changes the message it prints, b1012b 2026-10-31: name the test in Body:); how you verified (e.g. a test not run against the unfixed compiler) goes under Tests:.
