Topology and API

This is a nested lingtai-portal-guide reference. It covers the on-disk topology tape, replay chunks, HTTP endpoints, and live network JSON shape.

topology.jsonl

Each line is a TapeFrame:

json
{
  "t": 1744567890123,
  "net": { "nodes": [...], "avatar_edges": [...], "contact_edges": [...], "mail_edges": [...], "stats": {...} }
}

t is milliseconds since epoch. net is the same Network object /api/network serves; Network response shape below is a representative example of its core fields.

Replay chunks

Historical data is stored as delta-encoded, keyframed, gzipped JSON chunks bucketed by hour under .lingtai/.portal/replay/chunks/. The manifest.json in that chunks directory lists all available chunks with their time ranges and frame counts.

API endpoints

All endpoints are served at http://localhost:<port>.

| Endpoint | Method | Response | Description | |----------|--------|----------|-------------| | /api/network | GET | Network JSON | Live network state (nodes, edges, stats) | | /api/topology | GET | JSON array of TapeFrame | Full topology tape (can be large) | | /api/topology/manifest | GET | ReplayManifest JSON | Chunk metadata for replay | | /api/topology/chunk?start=<hourMs> | GET | Chunk JSON (optionally gzip-encoded when requested) | Frames for one hour-bucket start time | | /api/topology/progress | GET | JSON object such as { "current": N, "total": M } (or {}) | Reconstruction progress parsed from reconstruct.progress | | /api/topology/rebuild | POST | ReplayManifest JSON | Trigger tape reconstruction from source data and rewrite replay chunks |
