panics, and formal-verification.md publishes itFacts: Where things live, Traps already met, Commands
Score: S=3 (the owner’s 100 % target is only honest if the count covers every run-time check: an assert moved to a precondition (ADR-269 D5) is a check at its callers, and a panic is a run-time error claim (b) must count), O=1 (the lane’s own measure), C=4 M (a flag on lower-std, the script, one doc section). Area: prover. Must land before the lane puts asserts into tools/*.nika (#1053 step 8).
Pre-flight: p8 (#1076, 788981d), p10 (#1084, 76c216e) and p11 (#1090) are committed (git log --oneline -15 | grep -e 788981d -e 76c216e, and git log -15 --format=%B | grep "#1090"); if not, stop: Result: blocked, Needs: p8, p10 and p11 first (without them the claim count would report unproved preconditions as proved).
nikaia lower-std --bounds --asserts prints, for each tools file, its --bounds report as today and then its --asserts report (the block check --asserts prints, check_claims_report in check_facts.nika :720, the file’s path as --bounds prints it). --asserts without --bounds on lower-std prints the --asserts blocks alone. lower-std without either is unchanged. The --help text of lower-std (the paragraph on --bounds) says it in one sentence.scripts/proved.nika sums the asserts in header lines too and prints, after the proved: line, claims: N asserts, P proved (L through a loop), C preconditions proved at every call, U not proved (the header’s fields; a file with no assert adds nothing), then panics: K in F files (it reads the tools sources, crates/nikaia-std/src/tools/*.nika beside the script’s checkout, and counts panic( outside // comments: 13 in 9 files today), then left at run time: X = unproved indexes + unproved operations + U + K. That last line is the lane’s target figure: 0 is claim (b).asserts in lines (today’s --bounds alone) prints claims: not counted (run lower-std with --asserts) instead of the claims line, and left at run time without the U term, saying so.scripts/where.nika, 2026-10-31)crates/nikaia/src/main.rs :569 lower_std_bounds, :756 the Command::LowerStd dispatch (args.bounds :174, args.asserts :165).crates/nikaia/src/sysroot.rs :541 bounds_tools (add the asserts block per file; how check --asserts reaches check_claims_report for one file: follow args.asserts from main.rs :471 / :806).scripts/proved.nika (102 lines; number_before reads the header fields).docs/formal-verification.md §2 (lines 77-91, the figure paragraph) and §4 (line 120, Now (A)).tools/*.nika changes, so no lower-std re-lowering.sysroot.rs is also in the bug lane’s b17 (#1077, the tools preamble, :768-775), which may run beside you in the same checkout. Before committing, git diff crates/nikaia/src/sysroot.rs must show only your hunks; if it shows another’s, stage yours alone (your hunks into a patch file, git apply --cached it, then git add your other files by name and git commit -F the message without -a, not scripts/commit.nika, which would add the whole file; write Pushed: local <sha> into the report yourself) and say so in Body:. Never revert or stage the other hunks.cargo test -p nikaia --lib sysroot:: row only if one already covers bounds_tools (p1 found that a tests/compiler program cannot run a sysroot command); otherwise verify by hand and say so under Tests:: run target/fast/nikaia lower-std --bounds --asserts > R (about 45 s) and target/fast/nikaia run scripts/proved.nika -- R; quote the four lines under Tests:. Check a scratch copy of one tools file with one proved assert added is counted (in a clone or reverted by name at once; never commit it).--optimization prove-through-loops:on as the second run), into formal-verification.md §2 (replace the de2af5b2 figure paragraph: the commit, both settings, the claims and panics lines, left at run time) and §4 Now (A)’s percentages; the sentence “26 assert and 11 panic” is replaced by the counted figures. docs/writing-guide.md rules: no absolute claims, the measured commit named. Part: #1053.Changelog: write one sentence (lower-std --asserts is a toolchain change), not none.
Build, fmt, clippy, pre-push-check.sh; cargo test -p nikaia --lib sysroot:: bounds_report:: green; committed locally. Stop about 15 turns before max_turns, commit what is finished and report partial.
The change needs a file outside Locations; an error in another agent’s file.
Not yours, never stage: every file git status shows modified or untracked at your start (crates/nikaia-std/src/tools/lowered/project_members.rs is residue, #1060), and every docs/briefs/* file except your report.
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 (scripts/commit.nika -- REPORT does it); commit locally after each step and never push: the driver runs the complete suite and pushes (.claude/agents/builder.md, Cheap checks only; owner, 2026-10-31).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. No gate.nika.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: architect 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.Result: partial with what you ruled out, the probe, and the suspected file and function (.claude/agents/builder.md).target/fast/nikaia run scripts/commit.nika -- REPORT, which writes Pushed: local <sha> into it. 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)./home/user/Nikaia/docs/briefs/prover/p9-1053-claims-in-the-figure.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:.
