tngo 890e186182 test: cover the local scale branch and the decision policy ... The shipped default scale had no test: make_session only builds matcher-backend engines, so scale == "local" in _on_classified never ran in the suite - and that is the branch that was wrong twice (the rank re-sort, and the early return that made the text lane's fill-in job unreachable). Adds LocalScaleEngine, which injects the lanes' evidence into the live path, and two live tests: a text-only read still labels the track, and a text veto blocks a local accept. Adds DecisionPolicyTests for the veto/fill-in boundary, including the lane-order-vs-value case that the rank re-sort broke. Both regressions were re-injected to confirm the tests fail for the intended reason: restoring the early return fails the fill-in test, and re-sorting the lane output by value fails the order test.
