fix: make the test suite pass (12 failures tracked by #47)

[hyperpolymath]

Summary

This fixes the 12 test failures that #47 tracks. Each fix is in src/ at the root cause, or in a test that called an API that never existed. No test is skipped, deleted or loosened.

#	Failure	Root cause	Fix
1	Statistics Parsing / Parse numeric statistics, runtests.jl:876–881 (3 fail + 3 KeyError)	parse_statistics matched only a single-pair list (:key value) that closes at once. Solver statistics come as one list of many pairs, and Z3 prints it over several lines.	It now finds each (: keyword list and reads every :key value pair in it. Quoted strings are consumed first, so a (:…) inside an error message is not read as a list. Against real Z3 4.13.3 (get-info :all-statistics) output it returns 13 entries.
2	evaluate / Boolean logic, runtests.jl:931–932	Julia parses p && q and p || q as Expr(:&&) / Expr(:||), not as calls. The :call branch never ran, so the substituted Expr came back.	evaluate computes && and || once every operand is a Bool. If any operand is still unknown, it returns the substituted Expr.
3	Unsat core extraction (Z3), runtests.jl:1153	Two defects. First, set_option!(ctx, :produce_unsat_cores, true) sent the option name with underscores, which is not the SMT-LIB name (cvc5 1.1.2 answers unsupported). Second, plain check_sat(ctx) never sent (get-unsat-core), even with the option on.	The Symbol method of set_option! maps _ to -. check_sat's get_unsat_core now defaults to the context's produce-unsat-cores option. An explicit get_unsat_core=true/false behaves as before. Z3 now returns [:pos, :neg].
4	e2e declare → assert → check_sat, e2e_test.jl:23; e2e to_smtlib_script, e2e_test.jl:41; property assert! count, property_test.jl:31 (3 UndefVarError)	These tests were wrong. declare_const and to_smtlib_script have never existed in src/. Commit ed8eff1 added them only as calls, in the tests and in benches/benchmarks.jl.	The tests and benches now use the exported, documented API: declare(ctx, name, sort) (README: "declare(ctx, name, sort) — Declare a constant or function") and SMTLib.build_script(ctx, get_model). The "Script Building" testset already exercises build_script.

Why fix 4 changes the tests rather than adding declare_const. #47 leaves the choice open. Adding the two functions would give the package a second name for declare and a public wrapper around an internal function, and only test code from a single commit would use them. Keeping declare as the one public way to declare a constant is the simpler choice. The alternative, adding and exporting declare_const(ctx, name, ::Symbol) and to_smtlib_script, is easy to do if the owner prefers it.

No assertion is weakened, and two are stronger:

• "unknown sort raises an error" passed vacuously before. The UndefVarError for declare_const satisfied @test_throws Exception. The test now asserts that an unmapped type (Vector{Int}) raises a MethodError and that no declaration is recorded. I checked that declare(ctx, :z, Vector{Int}) really throws MethodError: no method matching smt_type(::Type{Vector{Int64}}).
• The pipeline test now also checks that exactly three (assert forms are emitted, as its own comment says.

CHANGELOG.adoc gains a === Fixed section under [Unreleased].

Second commit (318efef), from CodeRabbit's review. A quoted string that is not a pair's value could leak a false pair. On 6604a9c, (:a 1 "stray :time 99") gave time => 99; I reproduced this. CodeRabbit's own example, (:reason "message :time 99"), was already parsed correctly, because there the string is a value and is consumed whole. The pair search now consumes any stray string whole as well.

The commit adds 9 regression tests:

• Z3's multi-line layout;
• quoted values containing parentheses and :key value text;
• the stray string;
• an error message containing (:foo bar);
• a keyword value.

It also replaces the tautological isempty(stats) || !isempty(stats) in "Empty output" with isempty(stats).

Third commit (a6c6bc6): make the CI matrix able to run the tests. #47's last acceptance criterion is "Pkg.test() passes on the CI matrix (1.10, 1.11, nightly × ubuntu/macos/windows)". Two things stopped that, on main and on this branch before this commit:

• Every test (*) job stopped at Build package with expected package AcceleratorGate [59f742c7] to be registered. julia-buildpkg adds only General, and AcceleratorGate is in hyperpolymath/julia-professional-registry. CI.yml now passes that registry to julia-buildpkg through its existing localregistry input; the test step reuses the same depot. The registry needs no credentials: fix(ci): make the release workflow build, attest and publish #50's Release run passed its "Add registries" step on a hosted runner.
• CI installs neither z3 nor cvc5. Four testsets (the three e2e SMTContext testsets and the property assert! count) only build SMT-LIB text, but they called SMTContext(), which looks a solver up on PATH and raises No SMT solver found. Install z3 or cvc5. These calls were already on main. They now pass SMTContext a solver record that is never run (SMTSolver(:z3, "/nonexistent/z3", "never run")). declare, assert! and build_script never read the context's solver; only run_solver does. The first of them is titled "(no solver)" and its comment says it "must not error even without a solver installed", so this makes the test do what it says.

Closes #47. All nine CI / test (*) jobs on this head (a6c6bc6) are green: run 37912491992. Eight passed on the first attempt. test (nightly, macos-latest) first failed at Setup Julia, before any package code ran, with getaddrinfo ENOTFOUND julialangnightlies-s3.julialang.org. That is a runner DNS failure; the host resolved and answered 200 from here. The job was re-run unchanged and passed (job 113764403648, 2026-10-09T09:50Z). 1.11, nightly, macOS and Windows are verified by CI alone; I ran 1.10 and 1.12 on Linux.

Type of change

• 🐛 Bug fix (non-breaking change that fixes an issue)
• ✨ New feature (non-breaking change that adds functionality). No new public function.
• 💥 Breaking change (would change existing behaviour). There are two small behaviour changes, both towards SMT-LIB-correct output. A Symbol option key now has _ mapped to -; the old underscore name was not a valid SMT-LIB option name. Plain check_sat now requests the unsat core when the context already enables produce-unsat-cores. String keys and explicit keyword arguments are unchanged.
• 🕳️ Soundness fix. Not a checker or proof false-negative.
• 📖 Documentation. The only doc changes are docstrings and the CHANGELOG entry.
• 🧹 Refactor / tech debt
• ⚡ Performance
• 🔧 Build / CI / tooling. CI.yml: julia-buildpkg gains the localregistry input (third commit).

📌 New pins

Head SHA: a6c6bc6

No pins added or changed. The julia-buildpkg pin (e3eb439f…, v1.7.0) is unchanged; only its with: input is new. There are no actions.lock changes (the repo has none) and no Project.toml compat changes. Manifest.toml is gitignored. CI.yml stays in block YAML, because this repo's gates do not yet meet the KYAML preconditions.

How has this been verified?

I ran Pkg.test() from a throwaway depot (General plus hyperpolymath/julia-professional-registry), with z3 4.13.3 and cvc5 1.1.2 on PATH, so the solver-dependent testsets, including the Z3 unsat-core test, actually ran:

Julia	main @ 487c7ab	6604a9c (first commit)	318efef (second commit)
1.12.6	818 pass / 6 fail / 6 error (830)	864 pass (864)	873 pass (873)
1.10.10	818 pass / 6 fail / 6 error (830)	864 pass (864)	873 pass (873)
1.11	not run, not installed on this machine	not run	not run

From main to the first commit, the total rises by 34:

• The property test now runs all 30 iterations instead of erroring on the first (+29).
• The e2e pipeline testset runs 4 checks instead of 1 error, including the new assert count (+3).
• The e2e build_script testset runs 2 checks instead of 1 error (+1).
• The unknown-sort testset gains the "no declaration recorded" check (+1).

The second commit adds 9 tests to "Statistics Parsing" (864 → 873). They are described below.

I also checked parse_statistics directly against these inputs:

• real Z3 multi-line statistics (13 keys; time → 0.0, max-memory → 17.82, num-allocs → 35972);
• the test string;
• a quoted value containing parentheses ((:name "Z3 (x)"));
• a keyword value ((:reason-unknown :incomplete));
• an error message containing (:foo bar), which correctly yields nothing.

The new check_sat default has one path that no test covers. When produce-unsat-cores is on and the problem is satisfiable, plain check_sat now also sends (get-unsat-core). I ran this case directly on both solvers:

• z3: status=sat, model x => 6, followed by (error "… unsat core is not available").
• cvc5: status=sat, model x => 6, followed by (error "Cannot get unsat core unless in unsat mode.").

In both cases the status and the model parse correctly.

The CI condition: no solver on PATH. For the third commit I also ran Pkg.test() with a PATH that has neither z3 nor cvc5 (command -v z3 cvc5 finds nothing; Sys.which is the package's lookup):

Julia, no solver	318efef	a6c6bc6 (head)
1.10.10	718 pass / 4 error (722), rc=1	757 pass (757), rc=0
1.12.6	not run	757 pass (757), rc=0

The 4 errors were the SMTContext() calls described above. 757 = 718 + 39: the four testsets now run their 5 + 2 + 2 + 30 checks. With z3 and cvc5 on PATH, the head still gives 873 pass (873) on 1.10.10, the same as 318efef.

CI note: the solver-dependent testsets ("Solver Integration", the Z3 optimisation and unsat-core tests) log No SMT solver found, skipping … and run only where a solver is on PATH, so CI does not exercise them. Installing a solver in CI is a separate change.

Checklist

• My commits are signed. All three commits are SSH-signed: git log --format=%G? gives G for each. GitHub reported verified: true (valid) for the first two, and the GraphQL commit signature reports VALID (signer hyperpolymath) for the third.
• I ran the project's own checks/tests locally and they pass. Pkg.test() passes on 1.12.6 and 1.10.10, with and without solvers, as above. 1.11 was not run. actionlint passes on CI.yml.
• New files carry the correct SPDX-License-Identifier. No new files; every touched file keeps its existing header.
• Docs are updated, and no public claim now overstates what the code does. The docstrings for parse_statistics, evaluate, check_sat and both set_option! methods describe the new behaviour. The two set_option! methods had no docstring before.
• I have not introduced a soundness hole (or I have flagged where I might have). The check_sat default only adds a (get-unsat-core) request when the user has turned unsat cores on.

Notes for reviewers

• Decision for the owner: test: 12 pre-existing test failures surfaced once the package loads (get_statistics, evaluate &&/||, Z3 unsat core, declare_const) #47 offers two paths for fix 4. This PR keeps declare as the only public way to declare a constant (see above). Say if you want declare_const added instead.
• Findings, not fixed here (out of scope):
  • CI installs no SMT solver, so the solver-dependent testsets are skipped there (see the CI note).
  • parse_unsat_core reads one line. cvc5 1.1.2 prints the core one label per line (( / pos / neg / )), so cvc5 cores come back empty. The test is Z3-only, so this is not one of the 12 failures.
  • cvc5's statistics format, (:all-statistics (("name" v) …)), is a nested list. parse_statistics deliberately skips it rather than producing wrong values.
  • The estate docstring scanner (standards/.githooks/docstring-scan.sh) skips .jl files, so it reported no verdict (skipped=4). I checked the docstrings by hand.

Before / after behavior

• observed — Modified behavior in CHANGELOG.adoc: Added a Fixed section documenting the listed parser, expression-evaluation, option-key translation, unsat-core default, and test/benchmark call-name fixes.
• observed — Modified behavior in benches/benchmarks.jl: The declaration-and-assertion benchmark replaces declare_const(ctx, :x, :Int) with declare(ctx, :x, Int) and replaces to_smtlib_script(ctx) with SMTLib.build_script(ctx, false). The ten-constant benchmark likewise replaces declare_const with declare, passing Int rather than :Int.
• observed — Modified behavior in src/SMTLib.jl: set_option! adds a Symbol-key overload that translates underscores to hyphens and stringifies the value. The String-key overload now accepts any value and stringifies it; previously the Symbol overload preserved underscores when forwarding its key.
• observed — Modified behavior in src/SMTLib.jl: The String-key method’s documentation now states that option names are verbatim and values are stringified; the former Symbol overload implementation was replaced by this documentation and the broadened String method.

Addressed in 318efef. CodeRabbit acknowledged the fix and resolved its own thread at 2026-10-09T09:23:41Z, and all 5 pre-merge checks pass on the current head a6c6bc6. Dismissed because the bot acknowledged the fix but left its CHANGES_REQUESTED in place; per the owner ruling, CodeRabbit does not block a merge.
