Spanda

Stitched workflows

Multi-feature .sd programs with step-by-step CLI sequences that connect language declarations to platform commands. Use these after the minimal features/ snippets and before full showcase/ demos.

Feature options reference: platform-feature-examples.md

Workflows

Workflow File Features stitched Primary commands
GPS loss full stack gps_loss_full_stack.sd Decision trees, offline policy, recovery, continuity, homeostasis, attention, assurance decision list, heal, recover, continuity, sim --inject-failure, assure
Offline signed autonomy offline_signed_autonomy.sd Offline policy, decision tree, recovery, signing, attack simulation decision sign-policy, sign-tree, cache show, simulate --offline, simulate-attack
Fleet patrol handoff fleet_patrol_handoff.sd Multi-robot fleet, continuity, recovery, succession, takeover succession, takeover, delegate, continuity, fleet run
Differentiation audit trail differentiation_audit_trail.sd Decision trace, audit, explain, contract verify sim --record, audit decisions, explain decision

Suggested order

  1. GPS loss full stack — see how decisions, recovery, and continuity compose on one rover
  2. Offline signed autonomy — policy signing, cache, and offline abuse simulation
  3. Fleet patrol handoff — multi-robot handoff and fleet coordination
  4. Differentiation audit trail — decision trace audit and explainability

Adding a stitched workflow

  1. Create examples/workflows/<name>.sd with a header comment listing the full command sequence
  2. Combine at least three platform features (e.g. decisions + recovery + continuity)
  3. Add a row to this README
  4. Link from platform-feature-examples.md
