- Developed ComposerLockReader to load and parse composer.lock files asynchronously.
- Introduced ComposerPackage class to encapsulate package details.
- Added PhpPackage class to represent PHP packages with metadata and evidence.
- Implemented PhpPackageCollector to gather packages from ComposerLockData.
- Created PhpLanguageAnalyzer to perform analysis and emit results.
- Added capability signals for known PHP frameworks and CMS.
- Developed unit tests for the PHP language analyzer and its components.

Graph Indexer packaging (Runtime & Signals 140.A)

Deployment overlays

  • Helm/Compose should expose two timers for analytics: GRAPH_ANALYTICS_CLUSTER_INTERVAL and GRAPH_ANALYTICS_CENTRALITY_INTERVAL (ISO-8601 duration, default 5m). Map to GraphAnalyticsOptions.
  • Change-stream/backfill worker toggles via GRAPH_CHANGE_POLL_INTERVAL, GRAPH_BACKFILL_INTERVAL, GRAPH_CHANGE_MAX_RETRIES, GRAPH_CHANGE_RETRY_BACKOFF.
  • New Mongo collections:
    • graph_cluster_overlays — cluster assignments (tenant, snapshot_id, node_id, cluster_id, generated_at).
    • graph_centrality_overlays — degree + betweenness approximations per node.
    • optional node updates write attributes.cluster_id when WriteClusterAssignmentsToNodes=true.

Offline kit alignment

  • Cluster/centrality overlays are exportable alongside nodes.jsonl/edges.jsonl; keep under artifacts/graph-snapshots/{snapshotId}/overlays/ for air-gapped imports.
  • Seed bundle layout:
    • clusters.ndjson — overlay records (one per node) matching graph_cluster_overlays schema.
    • centrality.ndjson — overlay records with degree/betweenness.
    • manifest.json — references snapshot manifest hash and run timestamps.
  • Determinism: overlays ordered by node_id (ordinal) to keep bundle hashes stable.

Observability hooks

  • Metrics (Meter StellaOps.Graph.Indexer):
    • graph_analytics_runs_total, graph_analytics_failures_total, graph_analytics_duration_seconds, graph_analytics_clusters_total, graph_analytics_centrality_total.
    • graph_changes_total, graph_backfill_total, graph_change_failures_total, graph_change_lag_seconds.
  • Recommended alerts: lag > 5m, failures > 0 over 10m window, cluster job duration > 2m.

Configuration defaults

  • Cluster/centrality intervals: 5 minutes; label-propagation iterations: 6; betweenness sample size: 12.
  • Change stream: poll every 5s, backfill every 15m, max retries 3 with 3s backoff, batch size 256.

Notes

  • Analytics writes are idempotent (upserts keyed on tenant+snapshot+node_id). Change-stream processing is idempotent via sequence tokens persisted in IIdempotencyStore (Mongo or in-memory for tests).
  • Keep Helm/Compose values in sync with these defaults when publishing the Runtime & Signals 140.A bundle.
