Adding a dependency
# spanda.toml
[dependencies]
spanda-gps = "0.1"
import positioning.gps;
Registry provenance (provider wiring)
Built-in provider bootstrap uses provenanced dependencies only — not every package name in the
official catalog.
| How you depend |
bootstrap_providers_for_packages wires live backends? |
spanda-gps = "0.1" (registry) |
Yes |
spanda-gps = { path = "../../packages/registry/spanda-gps" } |
Yes (canonical monorepo tree) |
spanda-gps = { path = "../my-fork" } |
No — stub .sd only |
Path or git overrides of official names emit an official_provenance validation warning. Production
deploy gates block them. See how-packages-work.md.

Status
| Tier |
Packages |
Runtime behavior |
| Live transport |
spanda-mqtt, spanda-ros2, spanda-dds, spanda-ble, spanda-wifi |
Workspace transport crates registered via bootstrap_providers_for_packages(); comm-bus routes through ProviderRegistry |
| Live platform |
spanda-fleet, spanda-ota |
spanda-fleet and spanda-ota workspace crates; core shims for CLI |
| Capability grant |
spanda-nav, spanda-slam, spanda-ledger, spanda-cloud |
Capabilities granted when installed; nav/slam register package stubs in bootstrap |
| Scaffold |
Remaining packages |
Minimal .sd exports; smoke tests where present |
Spanda-language package sources remain scaffolds for most domains. Live vendor I/O is implemented in
workspace crates and core compatibility shims until each package gains full *Provider
registration. See lean-core-roadmap.md.
