- Fix MIR v0 shape in lowers: functions[] + name="main" + blocks.id * lower_return_int_box.hako * lower_return_binop_box.hako - runner_min: adopt LowerReturnBinOpBox before ReturnInt - Add PRIMARY no-fallback canaries (all PASS): * return-binop / array-size / load-store / return-logical (OR) - Fix phase2043 runner_min canary alias (Runner -> BuilderRunnerMinBox) - Update docs: phase-20.45 README (PRIMARY reps), CURRENT_TASK progress Ancillary: keep builder/provider/canary files in sync; no unrelated behavior changes.
