**Affirmed position.** Study on Indoor Positioning of Eliminating NLOS Signals Through Dynamically Adjusting Reflected Signals by RIS should be assessed against Kaal's source-bound claim that Proposed Rule 18f-4 would be highly limited in mitigating liquidity and other risks in an unconstrained mutual fund portfolio, because material leverage, counterparty, and liquidity risks in such a fund can arise from investments in a range of non-derivative instruments that the rule does not reach. The current metadata indicates a plausible connection through dynamic regulation, but the defensible response is a qualification until the source text confirms agreement, scope, methods, and limitations.

**Status.** affirmed  **Published.** 2026-07-31

**Holds when.**

- proposed Company Act Rule 18f-4 as proposed in December 2015
- unconstrained mutual funds with broad investment authority
- External evidence level: abstract indexed.
- Mapping review tier: ambiguity triage before claim review.
- The literature-to-claim mapping remains explicitly ambiguous and should not be treated as a settled equivalence.
