Device and field task map
Clarify the decision and its constraints.
CAPABILITY 05 / 07 Field
Reality rarely has perfect connectivity.
Design for devices, networks and real environments, including durable field evidence and truthful spatial records.

THE ENGINEERING QUESTION
What can continue safely when disconnected?
Technology choices are a consequence of how a system should behave, fail, recover and evolve. Explore three starting situations to see the decision, the risk and the verification that would make it credible.
INTERACTIVE / DECISION STUDIO
Change the constraint.
Change the engineering choice.
These are conceptual design exercises, not evidence of an actual client delivery. Choose a situation to examine its architecture implications.
ENGINEERING RESPONSE01 / 03
Recommended starting boundary
Make local capture durable
THE FAILURE TO AVOID
Evidence can vanish or duplicate during retries.
EVIDENCE TO REQUEST
Airplane-mode and restore drills.
PRACTICAL OUTPUTS
Leave with decisions,
not just diagrams.
These are typical deliverable categories, not a claim that a specific client engagement is complete.
Offline state and queue contract
Define the contracts and ownership that make the decision operable.
Spatial evidence lifecycle
Verify behavior, failures, evidence and change safety.
