fix(config): store trusted integers and harden seed controls - #939
fix(config): store trusted integers and harden seed controls#939cursor[bot] wants to merge 13 commits into
Conversation
Strix VULN-0001 failed the current head because MLS2PLMConfig and FitConfig could be constructed with values that bypass memory-safety bounds until a later explicit validate() call. Run the existing validators from __post_init__ so invalid objects cannot exist, and keep validate() public and idempotent.

Write admitted NumPy integers back as built-in ints so n_items and seed + restart cannot wrap, and reject untrusted seed/verbose values before construction returns. Co-authored-by: Seongho Bae <seonghobae@users.noreply.github.com>
Preserve current simulation resource caps while replaying the hostile integer-control boundary and focused evidence from #939 onto the protected-main tree.

Reviewed current exact head 6bfadea. The change is confined to configuration validation/marshalling and tests/docs/fuzz harnesses; it rejects caller-controlled integer coercion, normalizes admitted NumPy integer scalars to built-in ints, preserves Rust ownership of numerical psychometric computation, and current exact-head required/security checks are terminal-success with no unresolved review threads.

Pull request overview
OpenCode cannot approve yet because required coverage evidence did not pass.
Review outcome
1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence
-
Problem: The required coverage-evidence job result was
failure, so OpenCode cannot establish approval sufficiency for this head. -
Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.
-
Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports
successwith required evidence or explicit no-source not-applicable evidence. -
Regression test: Keep the approval branch checking
needs.coverage-evidence.result == successbefore posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present. -
Result: REQUEST_CHANGES

@opencode-agent Please re-review the unchanged exact head |
dimensionality_diagnostics still multiplied untrusted NumPy k_folds and added untrusted seed offsets, so uint8(32)*32 wrapped past the fit-budget cap and uint8(250)+6 wrapped to 0. Store built-in ints the same way seed/verbose already do. Co-authored-by: Seongho Bae <seonghobae@users.noreply.github.com>

📝 WalkthroughWalkthroughThe change hardens integer validation for simulation, fitting, and dimensionality diagnostics. It rejects unsafe coercion callbacks, booleans, and caller-defined integer subclasses. It accepts supported integer scalars, normalizes them to built-in integers, validates configurations during construction, and adds regression and fuzz coverage. ChangesInteger Validation
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: ⚪ Minimal · up to The change stores trusted configuration integers as built-in values, preventing overflow and callback-related inconsistencies in simulation and fitting.

Independent last-push review of exact head be50b5e72a9b7c23ef638532d8c2ed2cbcd54592.
Product slice is a real integer-trust repair: dimensionality_diagnostics now marshals k_folds/seed/latent_dims through _trusted_integer so uint8 wrap cannot skip the 1000-fit budget or zero a seed offset. Same marshalling as seed/verbose. No dummy commit. Likelihood/estimator/quadrature stay out of Python.
Product CI on this SHA is green: rust, python, python 3.12, python 3.14, fuzz, gpu-smoke, package, coverage-evidence. Prefer this head over #873.

fit_diagnostics still coerced parameter_count with int() and left m2_q_* untrusted, so a hostile __index__ object could execute during AIC/BIC arithmetic. Marshal those controls through _trusted_integer the same way seed/verbose already do. Co-authored-by: Seongho Bae <seonghobae@users.noreply.github.com>

Real wrap: fit_diagnostics now marshals parameter_count and m2_q_* through _trusted_integer, so hostile __index__ cannot run during AIC/BIC. Same path as seed/verbose. Likelihood/estimator/quadrature stay in Rust. Last-pusher cursoragent, author cursor[bot]. Prefer this head over #873.
Product CI on this SHA is green: rust, python, 3.12, 3.14, fuzz, gpu-smoke, package, coverage-evidence (95565442456), Strix (95565334167). Do not churn SHA. Leftover OpenCode CRs 4953595634 and 4956094214 remain on old heads and still block squash.

Superseded by #951 after normal non-force branch reconciliation in #1001. Fresh ancestry at decision time:
The reconciled #951 tree preserves this PR's complete callback-free integer allowlist, construction-time validation, built-in-int normalization, resource-bound tests, fuzz/doctoring/changelog evidence, and also carries the compatible Rust-required automatic-backend buyer/runtime contract. Keeping both PRs open would create duplicate landing vehicles for the same config/test changes. Do not merge both. |

Scope
Successor to #873 / #872. Construction-time validation on

Those stored scalars wrap:np.uint8(16) * np.uint8(16)becomes0, son_itemsandsimulate()can disagree with the validated size product, andconfig.seed + restartcan wrap a restart index. Save-timeint(config.seed)can still dispatch__index__.This branch keeps the #873 integer allowlist and construction-time
