Project context
Fictional information-display gateways receive brightness schedules and cache limits. These settings affect only a software display emulator; no real devices, safety controls or customer data are used.
Setup prerequisites
- Define synthetic configuration schema and supported device capabilities.
- Implement local control-plane and gateway adapters with delayed messages.
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
- CCONFIG-101 · Validate emulated display brightness and cache-limit settings
- CCONFIG-102 · Keep desired and reported edge configuration separate
- CCONFIG-103 · Scope emulated gateway configuration reads by organization
- CCONFIG-104 · Reject stale configuration revisions arriving at the edge gateway
- CCONFIG-105 · Stage edge settings before committing a complete configuration
- CCONFIG-106 · Reject edge settings unsupported by the declared gateway capability version
- CCONFIG-107 · Persist edge-configuration acknowledgement after active settings commit
- CCONFIG-108 · Coalesce offline edge configuration deliveries to the latest eligible revision
- CCONFIG-109 · Expose edge-configuration rollback as a new desired revision
Acceptance criteria
- Summary shows desired and reported revisions
- Payload values are omitted
- Offline uncertainty is explicit
Implementation constraints
- Use aggregate synthetic fleet observations only.
Verification to include
- Inspect converged gateway
- Inspect offline and incompatible gateways
Deliverables
- Drift report and data-exclusion cases
Rollout and recovery
Disable detailed diagnostics if configuration values leak.
Value of the work
For the engineer: Practice desired/reported state, compatibility and rollback.
For the team: Inspect whether remote configuration preserves working settings through offline and partial outcomes.
Evidence boundaries
Outcome Evidence: Tests, patches, and runbooks are requested deliverables. They become Outcome Evidence only through a qualified Mission and immutable Evidence IDs.
Ownership Evidence: Independent adaptation must be observed under a declared verification policy and cite immutable Evidence IDs. Completing a planning ticket establishes no Ownership Evidence.
