The runnable GER40/FRA40 examples baked `const PIP_SIZE = 1.0` and a dead pip column in the compare INSTRUMENTS table — a second source of pip truth parallel to the vetted `aura_ingest::instrument_spec` channel the CLI `--real` path already uses (#22). Route them all through one `pip_size_of(symbol)` helper: build_harness sources GER40 internally, ger40_breakout_blueprint gains a `pip_size` first arg fed from the lookup, and compare's run_cell sources each instrument's pip per cell. Value-identical (GER40/FRA40 both resolve to 1.0) and behaviour-preserving: the gated determinism / blueprint param-space / world tests stay green unchanged, and the frozen `sim-optimal(pip_size=1)` broker-label pins are untouched. closes #98
