ChangesTestlet control validation
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The change hardens public control validation, but large integer inputs can still produce an unintended exception and two regression cases do not exercise the intended rejection path because of duplicate arguments. Merge should wait for these localized correctness and test fixes. Sequence Diagram(s)sequenceDiagram

In `@python/fast_mlsirm/testlet.py`:
- Around line 154-156: Wrap the float conversion for tol and init_sigma2 in
their respective validation paths so integer-to-float OverflowError is converted
to the existing ValueError message. Preserve the finite and non-negative checks
and ensure both parameters raise ValueError for oversized integer inputs.
In `@tests/test_testlet_control_callbacks.py`:
- Line 118: Remove the explicit q_gamma=7 argument from the fit_testlet call in
the q_gamma parametrization, leaving the parametrized keyword/value expansion to
supply q_gamma once so the test reaches and verifies the expected ValueError.

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
-
Reason: coverage-evidence result was
failure, so required test/docstring evidence was not proven for current head3105b479c3914956e071428934e95a663f3c924f. -

Scope
Harden the public testlet-calibration marshalling boundary without changing the Rust-owned testlet likelihood, EM/SQUAREM estimation, quadrature, variance-component arithmetic or scientific interpretation.
Protected
mainadmitted broad Python/NumPy scalar subclasses and then normalized them with caller-dispatchableint(...),float(...),str(...)orbool(...). A hostile subclass/object could therefore execute conversion or representation callbacks before trusted Rust dispatch.Test-first lineage
