A ^Record param hint was applied only at the final re-emit (reinfer-def), not during the inter-procedural fixpoint. So a hinted param with no callers stayed :any while inference ran, and a field read off it (e.g. (:origin ^Ray r)) never told a non-inlined callee that its arg is a Vec3 — the callee's params stayed unproven and its field reads kept the dynamic guard. Seed declared hints as a param-type floor in the fixpoint: phint-seed (passes/ types) resolves an arity's :phints to positional record types via the record-shapes registry, and infer-unit! initializes each fn's fresh param slots from them instead of nil. A fixed declared type can't poison the least-fixpoint the way an early-iteration :any would, and a hinted param now propagates its (and its field reads') types to its callees during inference. Scope: this closes the hinted-propagation gap. It does NOT help the ray tracer, which uses zero ^-hinted params (only hinted fields) — its remaining type gap is unhinted record-param inference on recursive/non-inlined hot fns, and per the jolt-15jq A/B it's allocation-bound regardless (jolt-8flj).
