Data Update: Olaoluwa Osuntokun 1 -> 3 (No Known View -> Cautious)

Evidence
Olaoluwa Osuntokun (Lightning Labs CTO, BIP editor) posted twice on the bitcoin-dev mailing list in December 2025 in the "Hash-Based Signatures for Bitcoin's Post-Quantum Future" thread:
Post 1 (Dec 9, 2025): Analyzed DilithiumRK (a Dilithium variant) that enables BIP-32-like key derivation for post-quantum wallets. Described the mechanism (removes public key compression step to preserve homomorphic properties), outlined trade-offs (signatures larger, signing 2.7x slower, verification 1.75x slower). Also referenced a published BIP-32-like scheme for Falcon signatures, noting the 24KB signature size blowup. Discussed BIP-360 tap trees as a target derivation structure.
Post 2 (Dec 10, 2025): Analyzed NIST's plans for SPHINCS+ smaller parameter sets at the 6th PQC Standardization Conference. Noted NIST plans to standardize rls128cs1/rls192cs1/rls256cs1 but will delay, citing security risks from parameter misuse. Engaged with the standardization timeline argument.
Score Justification
Score 3 (Cautious): "Acknowledges risk, not yet acting."
Osuntokun is actively engaged in the technical PQ research conversation — analyzing specific algorithm properties, derivation schemes, and NIST standardization timelines relevant to Bitcoin. He is not calling for urgent Bitcoin protocol changes or building solutions. His participation is research-evaluation, not advocacy.
