Verdict
No production defect on 88db84b. Identity-only integer admission and fail-before-_core_module() ordering match #879. Horn/Glorfeld arithmetic and Rust ownership are untouched. CodeRabbit nits (domain-neutral docstring, single ascontiguousarray) are already on this head.
Do not APPROVE or merge from this account (author is seonghobae). Do not merge #923 and #938 together.
Next action
Land #938 (test(parallel-analysis): lock remaining pre-discovery oracles) after its exact-head required checks are green, then close #923 as superseded.
If you prefer to keep #923 as the integration PR, cherry-pick 63799d99 onto fix/parallel-analysis-control-safety-879 and close #938 instead.
Either head still needs exact-head python, rust, package, and Security Scan (osv-scan / dependency-review / trivy-fs) green. Queued checks on this synchronize are not a blocker and are not merge evidence.
Residual oracles on this head
These are test locks, not wrapper bugs:
- Workspace and
seed=2**64still use a dispatch trap, so they do not prove fail-before-discovery. np.bool_is rejected in code and untested here.- Distinct
np.longlong/np.ulonglongidentities are allowlisted and omitted from the happy-path parametrize.
#938 closes those three oracles. Local tests/test_parallel_analysis_control_bounds.py: 34 passed.

Add np.bool_(True) next to True for each control. Sibling control suites already do this; without it, n_iterations=np.bool_(True) becoming 1 would not be caught here. The successor locks this in #938.

_install_core(..., _TrapCore()) does not observe _core_module() itself. If discovery moved above _validate_random_workspace, this test would still pass. Point this path at _reject_core_discovery and assert discovery_calls == []. Same for the seed=2**64 test below. #938 does that.

On current NumPy, np.longlong and np.ulonglong are distinct from int64/uint64. They are in the production allowlist but missing here, so a later allowlist edit could drop them unnoticed. Parametrize the same 12 names the wrapper admits. #938 does that.

Scope
Fix #879 at the public parallel-analysis validation boundary without changing Horn/Glorfeld factor-retention mathematics or Rust numerical ownership.
