Configure V&V across all four declared kernel domains - #1

Conversation
realize dispatches on problem_family x grammar, and one of those pairs -- term_series / guarded_integer_sequence -- was declared in schema/realize.v0.json and handled in checker.py while shipping no spec at all. The CLI never ran it. Adds a declarative V&V matrix over all four domains, a dev-only runner, and an independent Lean corroboration layer. vv/domains.json declares four domains and 21 cases. Every domain must be observed reaching all four verdicts and an adapter reject -- a domain that can only be shown passing is a domain nobody has watched fail. Coverage is read out of realize.verdicts, so adding a grammar to the kernel fails the run until a domain arrives with it. Per-domain objectives: declared_semantics, outcome_coverage, tamper_evidence (one changed spec field costs a passing candidate its binding), no_self_grading (synthesize returns no verdict anywhere in its payload), and provenance (every non-null R and K clause cites a source). vv/lean/ re-states the same finite facts in Lean 4 and proves them with kernel-checked decide: core Lean only, no Mathlib, no native_decide, no sorry, no new axioms -- the runner refuses a file reaching for any of those before lean is invoked. Each file reports the quantities it settled; the runner recomputes all 29 from the Python kernel and compares. That comparison is what catches a frozen count in tests/test_counts.py edited to match a drifting kernel, which the Python suite cannot catch because the suite is what was edited. The product surface is unchanged: no new CLI verb, no fifth outcome. The runner exits 0/1 rather than on the verdict scale, is dev-only, and cannot mint a PASS. NONCLAIMS 10-11 record what Lean agreement and a green V&V run do not establish. VV.md carries the argument, including why validation stays open.

CI failed on `ruff check src tests scripts` with 10 RUF100 errors. The cause was mine: widening the lint path to all of scripts/ was not part of this change, and it pulled the pre-existing scripts/export_web_fixtures.py into scope along with it. ruff 0.16 dropped E402 from its default rule set and enabled RUF100, so every `# noqa: E402` marker in scripts/ now reads as unused. Those markers are also load-bearing under ruff 0.15, where E402 is still enabled -- so a file needing them cannot be clean under both, and pyproject allows ruff>=0.6. Rather than pick a ruff version, scripts/vv.py no longer needs suppression at all: the realize imports sit at the top of the module inside a try block, with the src/ path fallback in the except branch for a checkout that has not been pip-installed. Verified clean under both 0.15.8 and 0.16.8, and the fallback itself is now exercised -- with realize uninstalled the runner still reaches all four domains green. CI lints scripts/vv.py by name instead of the whole directory. The stale noqa markers in scripts/export_web_fixtures.py are left alone; they are pre-existing and belong to whoever widens the lint scope on purpose. Reproduced the failure first with `python3 -m ruff` -- a stale ruff 0.15.8 in ~/.local/bin was shadowing the pip-installed 0.16.8 that CI resolves.

URL, then verify the downloaded installer against its expected checksum before
execution. Ensure checksum failure prevents sh from running, while preserving
the existing toolchain selection from vv/lean/lean-toolchain.

- Around line 470-473: Update the fact collection loop in the cross-check flow
to detect repeated names instead of overwriting entries in reported. Track
duplicate fact names, require every expected fact to occur exactly once, and
fail the cross-check when a name is duplicated, including duplicates originating
from different Lean files.

success requires exit code 0 and the expected “fact” output, rather than no
output. Keep the existing command and surrounding documentation unchanged.

CodeRabbit's pre-merge docstring check read 53.57% against an 89% threshold, scoped to the two files this PR adds. Thirteen functions carried no docstring: run_cli, fail, meet, objective_determinism, run_domain, render, main and the three helpers nested in python_facts, plus three in tests/test_vv.py. Every module in src/realize/ documents its functions, so the gap was this PR drifting from the repo's own habit rather than a threshold worth arguing with. Now 28 of 28. No behaviour change. Verified: ruff clean under 0.15.8 and 0.16.8, 54 tests, V&V objectives met with all 29 Lean facts compared, no web-fixture drift.

Four of CodeRabbit's five findings were valid and are fixed. The fifth was not. Duplicate Lean fact names (Major, valid). The collection loop let a later `fact` line overwrite an earlier one, so a second file could supply the value the owning file got wrong -- in a cross-check whose whole job is catching drift. A repeated name now fails the run even when both copies agree, since agreement is exactly what would hide the overwrite. Confirmed: Grid.lean re-reporting series.syntactic_121 with the correct value now fails. Elan installer (Minor, valid). vv-lean fetched elan-init.sh from mutable master and piped it to sh on pull_request. Now pinned to revision 0e36a07 and checksummed before execution, so a tampered installer fails the step instead of running; verified by corrupting a copy and watching the gate refuse it. The pinned revision is byte-identical to what the job already ran. Added `permissions: contents: read`, which is what zizmor flagged and all three jobs need; artifact upload uses the runtime token, not this one. Provenance (Minor, valid). Four specs cited a NONCLAIMS section explaining the case rather than the source of R. That is precisely the sloppiness the provenance objective exists to catch, and it passed the gate -- a citation that does not cite. Each now names its origin, and the unrecognized-phrase spec says plainly that it has no source, because it does not. README (Minor, valid). vv/lean/README.md claimed success was "exit 0 and no output". The files emit `fact` lines now; success is exit 0 with only those. Lean placeholder (Critical, NOT valid). The finding says `(realizes . .larger)` prevents Formula.lean from running. It does not: ASCII `.` and `·` are both accepted, verified to compute identically and non-vacuously, and vv-lean passed on the commit under review with that exact line. Normalized to `·` anyway, for one spelling per file -- style, not a defect. Verified: ruff clean under 0.15.8 and 0.16.8, 54 tests, all four domains, 29 facts compared, no web-fixture drift, workflow YAML parses.

Two follow-ups from #1, each needing a different treatment: one was mechanically closable, one was not. Lint debt (closable). scripts/export_web_fixtures.py carried three `# noqa: E402` markers that ruff 0.16 rejects as unused, while the same markers are load-bearing under 0.15 -- so the file could not be clean under both, and pyproject allows ruff>=0.6. It now uses the same try/except import shape as vv.py and needs no suppression, verified under 0.15.8 and 0.16.8 with the bare checkout fallback exercised. Both dev scripts with shebangs are now executable (EXE001), and CI lints all of scripts/ rather than vv.py by name. That widening is what broke CI in #1; this time every file in scope is clean under both versions first. Provenance (partly closable). The gate checked that a source string existed, not that it named anything. Four specs in #1 passed it citing NONCLAIMS.md -- the section explaining why a zero budget yields UNKNOWN -- as the source of the relation in R. A reviewer caught that; the gate could not. Three things about a citation are decidable and are now checked: that a constraining clause is cited at all, that the citation is not blank, and that it does not name one of this repository's own documents, which explain the package and are never where a clause came from. A clause with no origin declares that with `"unsourced": true` instead of narrating it, which is how formula_unrecognized_phrase now reads. The rule is split out as provenance_gaps() so it can be tested rather than only exercised, and tests/test_vv.py now pins the exact failure that got through: a repo document cited as an origin. A gate nobody has watched fail is the same problem as a domain nobody has watched fail. What does not close: whether a source names anything real. `VCOS §8.1 Table 2` and `asdf` are the same shape. `unsourced` is a bypass and takes the author's word. VV.md says so plainly, and says what changed is where the gap sits -- it used to hide inside citations that looked fine, and now it is a marker you can grep for. Verified: ruff clean under 0.15.8 and 0.16.8 across src, tests and all of scripts; 60 tests (was 54); four domains; 29 Lean facts compared; no web-fixture drift.

What this is
realizedispatches onproblem_family×grammar. That pair is the domain axis, and four pairs are reachable inchecker.py. One of them —term_series / guarded_integer_sequence— was declared inschema/realize.v0.json:61, dispatched inchecker.py:49,76, and unit-tested intests/test_series.py, while shipping no spec at all. The CLI never ran it.This adds a declarative V&V matrix over all four domains, a dev-only runner, and an independent Lean corroboration layer.
formula.bounded_coeff_templateexact_rationalencoder.finite_case_tablefinite_relationterm_series.typed_gridfinite_integerterm_series.guarded_integer_sequencefinite_integerVerification vs validation
The two questions V&V runs together (IEEE 1012, DO-178C):
realize check, and always was.So what is configured here is verification across the domain axis, plus the bookkeeping that keeps the validation gap visible rather than invisible: every clause that constrains must cite a source, and every certificate must carry the boundary its claim is good inside.
VV.mdstates this plainly, and NONCLAIMS gains §11 saying a green V&V run is not validation.The matrix
vv/domains.jsondeclares four domains and 21 cases.Every domain must be observed reaching all four verdicts and an adapter reject. A domain that can only be shown passing is a domain nobody has watched fail. Coverage is read out of
realize.verdictsat run time, so adding a grammar to the kernel fails the run until a domain arrives with it.Per-case objectives:
outcome,exit_table(the matrix's exit codes are checked againstverdicts.EXIT, so the documented table cannot drift from the code),exit_observed,determinism,scope_completeness.Per-domain objectives:
declared_semantics,outcome_coverage,tamper_evidence(change one spec field and a passing candidate loses its binding),no_self_grading(synthesizereturns noverdictanywhere in its payload),provenance.Lean
vv/lean/re-states the same finite facts in Lean 4 and proves them with kernel-checkeddecide. Core Lean only — no Mathlib, nolake, no network at check time. Rationals are carried as halves, since every coefficient inDis a whole number of halves.No
native_decide, nosorry, no newaxiom, no compiler overrides. The runner greps for all of these and refuses the file beforeleanis invoked, because a file that may assume things corroborates nothing.Proving things in a second language is not yet a cross-check, though — two implementations drift apart happily when nobody compares them. So each file reports the quantities it settled, and the runner recomputes all 29 from the Python kernel and compares. A disagreement fails the run, and so does a fact that quietly stops being reported.
That comparison is the one that bites when a frozen count in
tests/test_counts.pyis edited to match a drifting kernel. The Python suite cannot catch that, because the suite is the thing that was edited. Verified: withDwidened to six elements andtest_counts.pyedited to expect 1296, pytest goes green and the cross-check still fails onformula.template_card: lean '625' vs python '1296'.Facts are derived rather than restated.
series.witnessasks Lean to enumerate and take the shortest valid series; it and Python independently produceadd1,add3,add3— which is not the witnesstest_series.pyhappens to name, so the two sides agree about the enumeration and not just the answer.Product surface
Unchanged. No new CLI verb, no fifth outcome.
scripts/vv.pyis dev-only, is not part of the pip package, cannot mint aPASS, and exits0/1rather than on the verdict scale — a harness must not look like it is issuing verdicts.Gates were negative-tested

The first push failed CI, and the cause was in this PR: it widened the lint path to all of
scripts/, which dragged the pre-existingscripts/export_web_fixtures.pyinto scope.ruff 0.16 dropped E402 from its default rule set and enabled RUF100, so every
# noqa: E402marker inscripts/now reads as unused — while the same markers are still load-bearing under ruff 0.15, where E402 is enabled. Sincepyproject.tomlallowsruff>=0.6, a file that needs them cannot be clean under both.scripts/vv.pynow needs no suppression at all: itsrealizeimports sit at the top of the module inside atry, with thesrc/path fallback in theexceptbranch for a checkout that has not been pip-installed. Clean under both 0.15.8 and 0.16.8, and the fallback is now exercised — withrealizeuninstalled, the runner still reaches all four domains green.The stale markers in
