@jules Please strengthen the LSR tests before merge; current assertions mostly check ordering/centering and can stay green if ranking-to-chain semantics drift. On this same branch, keep the change tests-only and add: (1) one independent small 3-item full/partial-ranking numerical oracle that asserts the complete stationary weight/centered-log-worth vector; (2) public invariants |
I have completely rewritten the test suite in
All modified tests pass successfully across the local exact-head tests and Rust suites. |

One actionable finding:
The test reaches the Rust-backed public path:
The oracle is independent of the Rust stationary solver. It builds the documented continuous-time generator and solves the left-stationary problem with The tests use valid strongly connected alpha-zero ranking examples. They separately verify disconnected-graph failure at The checkout had moved to You are interacting with an AI system. |

In `@tests/test_scaling.py`:
- Around line 86-100: Update the duplicate-item assertion in
test_lsr_rankings_invalid_cases to match the public ValueError message produced
by lsr_rankings, using the core validator’s “duplicate item within a ranking”
wording instead of the unmatched “duplicates” regex.
- Around line 59-83: Update
test_lsr_rankings_permutation_invariance_and_repeated so the non-uniform
repetition case retains the weights returned by lsr_oracle and compares
res_nu.weights against them, in addition to the existing parameter comparison;
use the same appropriate numerical tolerances.
