Ultrametric Engine: Deploying a 20-Principle p-Adic Discovery Worker

Abstract

The theoretical framework developed in P1-P5 requires computational infrastructure to make ultrametric (p-adic) analysis accessible to experimentalists. We specify and deploy an ultrametric discovery engine — a Cloudflare Worker implementing 20 principles from the proven Ask QWAV production system. The Worker provides 27+ API endpoints including Bruhat-Tits tree construction, p-adic ranking via 3-phase discovery, dendrogram visualization data, and spectral analysis (Tate, Amice, intrinsic Amice transforms). Deployed on Cloudflare's edge network with D1, R2, and Vectorize bindings, the engine enables experimentalists to compute Gromov $\delta$ for their Majorana systems, classify ZBW transition graphs as ultrametric or Archimedean, and validate the ZBW Z₂ invariant predictions from P2-P3.

Keywords: Ultrametric engine, Cloudflare Workers, Bruhat-Tits tree, p-adic discovery, Gromov hyperbolicity, p-adic time clusters

2. Core Algorithms

2.1 3-Phase Discovery Engine

function suggestCorrections(query, titles, maxResults=5, maxDistance=5) {
  // Phase 1: Word-level Levenshtein matching (direct hits)
  const wordMatches = findWordMatches(query, titles, maxDistance);
  
  // Phase 2: Ultrametric cluster expansion (structural neighbors)
  const clusterNeighbors = expandClusters(wordMatches, ultrametricTree);
  
  // Phase 3: Tree-based search with strong-triangle pruning
  const treeResults = searchUltrametricTree(query, ultrametricTree, maxDistance);
  
  return mergeResults(wordMatches, clusterNeighbors, treeResults).slice(0, maxResults);
}

2.2 Ultrametric Tree Builder

function buildUltrametricTree(titles) {
  // Agglomerative single-linkage clustering
  // O(n³) ≈ 15M ops for n=451 — acceptable for Worker execution (2-3s)
  // Only single-linkage guarantees ultrametricity (strong triangle inequality)
  
  const n = titles.length;
  const dist = computeDistanceMatrix(titles);
  const clusters = titles.map((t, i) => ({ id: i, items: [t], height: 0 }));
  
  while (clusters.length > 1) {
    // Find closest pair (single-linkage = min distance between cluster members)
    let minDist = Infinity, minI = 0, minJ = 0;
    for (let i = 0; i < clusters.length; i++) {
      for (let j = i + 1; j < clusters.length; j++) {
        const d = singleLinkage(clusters[i], clusters[j], dist);
        if (d < minDist) { minDist = d; minI = i; minJ = j; }
      }
    }
    
    // Merge
    const merged = {
      id: nextId++,
      items: [...clusters[minI].items, ...clusters[minJ].items],
      height: minDist / 2,
      children: [clusters[minI], clusters[minJ]]
    };
    clusters.splice(Math.max(minI, minJ), 1);
    clusters.splice(Math.min(minI, minJ), 1);
    clusters.push(merged);
  }
  
  return clusters[0]; // Root of the ultrametric tree
}

2.3 p-Adic Cache TTL

function getPAdicCacheTTL(query) {
  // ord₂ = (maxDepth - queryDepth) / scale
  // TTL = 15s × 2^ord₂, capped at 960s
  // Foundational queries (shallow tree depth) get longer cache lifetimes
  const depth = computeQueryDepth(query);
  const ord2 = (maxDepth - depth) / scale;
  return Math.min(15 * Math.pow(2, Math.round(ord2)), 960);
}

4. Deployment Verification

4.1 Verification Checklist

• [x] /health returns papercount, chunksin_vectorize
• [x] /did-you-mean?q=quantm returns discoveries (cluster neighbors beyond word matches)
• [x] /ultrametric-tree includes all 19 statistical fields
• [x] /spectral-analysis includes intrinsicAmice (Principle #20)
• [x] Tree persists across cold starts via R2 (<100ms restore)
• [x] Gromov $\delta$ endpoint operational for external graph analysis

4.2 Integration with P3 Readout Protocol

The /gromov-delta endpoint directly supports P3 Protocol C: experimentalists upload their Majorana system's transition graph and receive a Gromov $\delta$ value with ultrametricity verdict. This enables:

1. Classification of ZBW signals as ultrametric vs. Archimedean
2. Comparison of $\delta{\text{Dirac}}$ vs. $\delta{\text{Majorana}}$ across different platforms
3. Validation of the ZBW Z₂ invariant prediction ($\delta{\text{Majorana}} < \delta{\text{Dirac}}$)

5. Limitations and Future Work

1. Cold starts: Worker cold starts add ~80ms latency on first invocation
2. Tree size: Current 451-paper tree is 1.2MB; scaling to 10,000+ papers would require D1-based incremental updates
3. Gromov $\delta$ computation: $O(n^4)$ for naive implementation; currently sampling 10,000 triples for speed
4. p-adic time clusters: Requires 30+ paper corpus with timestamps for meaningful clustering
