Root cause of HF + GitHub + section icons not appearing in the docs route: Next.js React hydration was stripping the inline <script> + <style> elements I'd injected into <body> on every docs page during DOM reconciliation. The script never registered its setInterval. Move the decorator to /zen-decorate.js loaded via <script defer src> in <head>. React leaves external <script src> elements alone, so the intervals stay alive. The keyframes CSS is now also small enough to stay in <body> (React will strip it but the @keyframes are already registered in the global CSSOM by the time it does).

<p>Current language models operate in bounded context windows. Information from past interactions must be explicitly retrieved or summarized. This creates several challenges:</p>
|
||
<ol>
|
||
<li><strong>Context limits</strong> : Models can only attend to finite token sequences</li>
|
||
<li><strong>Retrieval failures</strong> : Important context gets lost or incorrectly recalled</li>
|
||
<li><strong>No learning</strong> : Agents don’t improve from experience within deployment</li>
|
||
<li><strong>Trust gap</strong> : Users can’t verify what the agent “remembers”</li>
|
||
</ol>

<p>An experience ledger is an append-only log of agent experiences with cryptographic attestation. Think of it as a blockchain for agent memory, but optimized for AI workloads.</p>

<p><strong>Append-only</strong> : Experiences are added but never modified or deleted. This creates an immutable record of agent history.</p>
|
||
<p><strong>Content-addressed</strong> : Each experience has a unique hash based on its content. References are stable and verifiable.</p>
|
||
<p><strong>Selective disclosure</strong> : Agents can prove they have certain experiences without revealing all memories. Zero-knowledge proofs enable privacy-preserving verification.</p>
|
||
<p><strong>Hierarchical summarization</strong> : Raw experiences are continuously summarized at multiple abstraction levels. Agents can navigate from high-level patterns to specific instances.</p>

<p>We’ve built a reference implementation using:</p>
|

<ul>
|
||
<li><strong>Storage</strong> : Content-addressed blocks on IPFS</li>
|
||
<li><strong>Attestation</strong> : Ed25519 signatures for each entry</li>

<li><strong>Indexing</strong> : HNSW vectors with metadata filtering</li>
|
||
<li><strong>Summarization</strong> : Hierarchical abstractive compression</li>

<p>The system maintains consistency between layers. When raw experiences update, summaries regenerate. When summaries change, abstractions refresh.</p>

<li><strong>User control</strong> : Users own their ledger data</li>
|
||
<li><strong>Selective sync</strong> : Choose what experiences to persist</li>
|

<li><strong>Cryptographic deletion</strong> : Encrypted entries can be made unreadable</li>
|

<li><strong>Audit logs</strong> : All access is recorded</li>
