Decision: staying on Holographic for now.&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;A head-to-head comparison of two SQLite-backed agentic memory systems for Hermes Agent:&lt;/p&gt;
&lt;ul&gt;
&lt;li&gt;&lt;strong&gt;Holographic:&lt;/strong&gt; Local-first, zero-dependency memory provider with Phase Holographic Reduced Representations (HRR) for compositional retrieval. Unlimited database size, no accounts, no cloud roundtrips.&lt;/li&gt;
&lt;li&gt;&lt;strong&gt;Sibyl Memory:&lt;/strong&gt; Five-tier hierarchical schema (HOT/WARM/COLD/REFERENCE/ARCHIVE) with self-learning, LongMemEval-validated (95.6%), but requires cloud activation and has a 2 MB free cap.&lt;/li&gt;
&lt;/ul&gt;
&lt;h2 id="the-verdict"&gt;The Verdict&lt;/h2&gt;
&lt;p&gt;Sibyl wins on features and benchmarks. Holographic wins on operational simplicity — zero external dependencies, unlimited storage, trust-based fact management.&lt;/p&gt;</description></item></channel></rss>
