Recovery Graph

The recovery graph models entity relationships for dependency analysis, impact analysis, and recovery planning.

Graph views

View	Purpose
Dependency graph	Upstream dependencies (`depends_on`, `consumes`, `controls`)
Impact graph	Downstream entities affected by a failure
Recovery graph	Critical recovery paths

Example chain

Mission → Robot → Camera → Firmware → Provider → Package → Gateway → Cloud

Building the graph

use spanda_recovery::build_recovery_graph;

let graph = build_recovery_graph(&registry, Some("robot-1"));
let (upstream, downstream) = spanda_recovery::analyze_impact(&graph, "camera-1");

CLI

spanda recovery graph rover.sd --entity robot-1 --json

REST API

GET /v1/recovery/graph?entity_id=robot-1

GET /v1/recovery/recoverable-entities — list entities from the orchestrator registry (program robots overlaid when a program is loaded).

SDK

client.get_recovery_graph(Some("robot-1"))?;
client.list_recoverable_entities()?;

client.get_recovery_graph("robot-1")
client.list_recoverable_entities()

await client.getRecoveryGraph("robot-1");
await client.listRecoverableEntities();

Control Center

The Recovery tab in @davalgi-spanda/web RecoveryPanel loads /v1/recovery/graph and displays nodes and dependency/impact edges in tables alongside plan, simulate, and execute workflows. Role-gated actions require a Bearer token with Operate permission.
