From 5bcca4193fbb883c1200c4d5ab19d89c745363d4 Mon Sep 17 00:00:00 2001 From: magic5644 Date: Sat, 27 Jun 2026 19:18:58 +0200 Subject: [PATCH 01/29] feat(webview): add hub score visual indicator to ReactFlow file nodes File nodes now display border thickness proportional to their import count (hub score 0-100, normalized over visible nodes). Four tiers: 2px (<20), 3px (>=20), 4px (>=50), 5px (>=80). High-score nodes also render bold (>=50) and larger font (>=80, non-root only). Priority order preserved: selection > cycle > root > hub score. External dashed borders coexist with hub tiers. React.memo comparator updated to include hubScore to ensure re-renders on score changes. Coverage: FileNode.tsx 97%, buildGraph.ts 96%, 251 tests passing. --- package-lock.json | 231 +++++ package.json | 4 +- src/webview/components/reactflow/FileNode.tsx | 19 +-

NodeMetadataBuilder computes hubScore [0-1] from parentCounts in the analyzer layer, making Spider the single source of truth per ADR-F2-01. WikiGenerator reads externalNodeMetadata.hubScore when available, falling back to its DB-computed value. GraphViewService populates nodeMetadata after parentCounts. buildGraph.ts reads nodeMetadata with a fallback to computeHubScores for backward compat when nodeMetadata is absent. MCP types.ts adds GraphNodeMetadataSchema and GraphDataSchema Zod schemas. 477 tests passing, coverage: NodeMetadataBuilder 100%, buildGraph 96%, mcp/types.ts 86%. --- .../ADR-F2-01-hubscore-source-of-truth.md | 57 ++++ src/analyzer/NodeMetadataBuilder.ts | 44 +++ src/analyzer/wiki/WikiGenerator.ts | 14 +- src/extension/services/GraphViewService.ts | 8 +- src/mcp/types.ts | 41 +++ src/shared/graph-types.ts | 15 + src/shared/wiki-types.ts | 7 + .../components/reactflow/buildGraph.ts | 22 +- tests/analyzer/NodeMetadataBuilder.test.ts | 154 ++++++++++ tests/mcp/types.test.ts | 270 ++++++++++++++++++ tests/shared/graph-types.test.ts | 81 ++++++ .../components/reactflow/buildGraph.test.ts | 159 +++++++++++ 12 files changed, 862 insertions(+), 10 deletions(-) create mode 100644 docs/architecture/ADR-F2-01-hubscore-source-of-truth.md create mode 100644 src/analyzer/NodeMetadataBuilder.ts create mode 100644 tests/analyzer/NodeMetadataBuilder.test.ts create mode 100644 tests/shared/graph-types.test.ts diff --git a/docs/architecture/ADR-F2-01-hubscore-source-of-truth.md b/docs/architecture/ADR-F2-01-hubscore-source-of-truth.md new file mode 100644 index 00000000..0f5a7834 --- /dev/null +++ b/docs/architecture/ADR-F2-01-hubscore-source-of-truth.md @@ -0,0 +1,57 @@ +# ADR-F2-01 : Source de vérité hubScore + +## Status + +Proposed + +## Context + +Story F2 ajoute `nodeMetadata?: Record` à `GraphData` (src/shared/graph-types.ts). +`GraphNodeMetadata` inclut `hubScore: number`. + +`parentCounts?: Record` existe déjà dans `GraphData` et est transmis au webview. +F1 (mergée) a implémenté `computeHubScores(visibleNodes, parentCounts)` dans `src/webview/components/reactflow/buildGraph.ts` — normalise sur les noeuds visibles uniquement. +`src/analyzer/wiki/WikiGenerator.ts` calcule déjà un `hubScore` workspace-wide pour les articles wiki. + +Consommateurs qui ont besoin d'un hubScore stable : MCP (`graphitlive_analyze_dependencies` retourne `GraphData` sérialisé), CLI, export HTML F3, community detection F4 (Louvain). + +## Decision + +**Option A retenue : Spider (analyzer layer) est la seule source de vérité pour `hubScore`.** + +Spider calcule `hubScore = parentCounts[file] / max(parentCounts)` normalisé [0-1] sur le workspace entier, lors du full-crawl uniquement (pas de mise à jour incrémentale partielle pour éviter un `maxParentCount` sous-estimé).

Sur un bundle de 10.4 MB, l'ajout de 400 KB est acceptable en absolu, mais introduit quatre dépendances transitives (`graphology-indices`, `graphology-utils`, `mnemonist`, `pandemonium`) dont la compatibilité CJS/ESM avec esbuild n'est pas vérifiée — risque de conflit de build non justifié pour un gain de qualité nul à < 500 noeuds. + +3. **Déterminisme.** L'implémentation maison utilise un Fisher-Yates shuffle avec seed fixe, garantissant une partition reproductible entre runs. `graphology-communities-louvain` propose `randomWalk: false` mais ne documente pas de seed externe — le déterminisme est un contrat nécessaire pour la stabilité des exports HTML et des réponses MCP. + +4. **Arêtes dirigées.** Louvain maison traite les arêtes dirigées comme non-dirigées (somme in+out pour le calcul de modularité), cohérent avec la sémantique de couplage structurel entre fichiers. graphology-communities-louvain supporte nativement le mode `directed` mais sa modularité dirigée produit des communautés plus fragmentées sur des DAGs d'import — comportement moins lisible pour l'utilisateur final. + +5. **Maintenance.** 150 lignes TypeScript internes, sans surface d'API tierce à maintenir.
