fix: autoresearch issues #11-#15, and renumber post-tag work as 3.9.0 - #300
Conversation
…rate removable singularities `verified_no_roots` could only return "false" when a sign change was visible at the box's own endpoints, so any even number of roots defeated it: `x^2-2` was "false" on [-2,0] but "undecided" on [-2,2], which contains both roots. The witness search now subdivides the box, and the intermediate-value argument is stated over the box rather than over an interval — a box is convex, so two points at which the expression is rigorously proven to have opposite signs certify a root on the segment between them, which stays inside the box. That also lifts the test to several variables. Continuity, which the argument needs, is exactly what a successful full-box enclosure already certifies. A root that never changes sign (a double root) still answers "undecided"; nothing was weakened to buy completeness. `verified_integral` refused every sub-interval whose reciprocal enclosure contained zero, which put `int_0^1 ln(1+x)/x dx = pi^2/12` out of reach even though only the expression is singular there, not the integral. An integrand that splits as N(x)/D(x) with N(p) = D(p) = 0 is now enclosed through Cauchy's mean value theorem, from an enclosure of N'/D'. The two zeros are established symbolically — no numeric enclosure can prove a value is exactly zero — D' must be certified non-vanishing, and N and D must each enclose successfully, which is what certifies they are analytic and hence that the symbolic derivatives are the real ones. Genuine poles (1/x, sin(x)/x^2) are still refused. Integrable-but-not-removable singularities (-log x, 1/sqrt(1-x^2), x^x) remain refused, since no rigorous tail bound can be derived from the expression alone; the E-VALIDATED-003 message now names the location and says that an integrable singularity still has a finite integral this routine cannot certify, rather than implying the integral does not exist.

Issues #11, #12 and #15 from the 2026-08-14 autoresearch log, landed alongside #13/#14 (previous commits on this branch). #11 — Groebner results were write-only. The blocker was not a missing accessor but a lost variable ordering: a GbPoly stores exponent vectors, not names, and rosenfeld_groebner discovered its jet variables internally and discarded them. Adds expr_to_gbpoly (named in compute_raw's own docstring but never exported, which is why reduce() was uncallable), GbPoly.{n_terms, variables, terms, to_expr}, GroebnerBasis.{__iter__, __getitem__, polynomials, to_exprs, variables, order, eliminate}, and DAE.{equations, variables, derivatives, time_var, index}. Naming too few variables raises rather than silently misreading exponent slots. GroebnerBasis.eliminate was documented for releases but existed only in Rust; it is now bound. #12 — ode-dae.md documented constructors that do not exist. Rewritten, with every block executed by tests/test_docs_ode_dae.py. Docstrings added to DAE.new, ODE.new, lower_to_first_order, pantelides, rosenfeld_groebner and the RosenfeldGroebnerResult accessors, which had none, which is why the page was the only documentation. index is now exposed; differentiated is dropped rather than given a new result class. #15 — 17 zero-argument scalar accessors converted from methods to properties, found by parsing every #[pymethods] block rather than by eye. Matrix.rank(), ODE.is_autonomous() and PositivityCertificate.verify() stay methods: they do real work. RegularChain.n_vars beside .polys() was already correct under the rule and is untouched. No compatibility aliases. A static guard in tests/test_accessor_convention.py fails on any new zero-arg scalar accessor lacking #[getter]. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
`v3.8.0` was tagged at 74d2bf9 and `publish.yml` publishes on `v*`, so 3.8.0 is cut and on PyPI. Both PR #299 and this batch nevertheless appended to the CHANGELOG's 3.8.0 section, which left the released wheel permanently disagreeing with its own changelog — and is why an external run against the published 3.8.0 kept reporting behaviour we believed we had fixed. The 3.8.0 section is now byte-identical to the tag (verified by diff), and everything added after it moves to 3.9.0: the behaviour changes, fixes, additions and performance work from both batches. The silent-error corpus count stays at the 213 that actually shipped in 3.8.0, with the growth to 241 recorded under 3.9.0 instead. Version strings bumped in Cargo.toml (inherited by both crates via version.workspace) and pyproject.toml. Other 3.8.0 mentions are historical statements about that release and are left alone. 3.9.0 rather than 4.0.0 is a deliberate call: it matches how 3.8.0 itself shipped behaviour changes. Note that nothing in CI enforces this — `cargo semver-checks` gates `alkahest_cas::stable`, and the accessor break is Python-side only — so the changelog's before/after table is the only warning users get.
