Consume data-server's neutral InstrumentGeometry at the aura-ingest edge to cross-check the hand-authored vetted InstrumentSpec floor (#113) against provider truth, and add the two deferred deploy-grade fields (tick_size, digits) the sidecars now supply. Scope fork derived and recorded on #143: this cycle does NOT build #124's runtime resolver and does NOT change quote_currency's &'static str type (the geometry tier carries non-FX currency as String). Auto-signed autonomously under /boss on a grounding-check PASS (6/6 assumptions ratified); reply to the run to veto. refs #143
