The board opens an editable draft; nothing is saved until you confirm it. Sign-in and workspace permissions apply, and Demo boards remain ephemeral.
Project context
A fictional product team creates local preview environments for pull requests. Names collide, fixtures copy more data than needed, failed provisioning leaks resources, and merged changes leave previews running. Build an infrastructure simulator with fake DNS, storage, and deployment providers; no cloud account or live domain is supplied.
Setup prerequisites
- Resource graphs
- Idempotency
- Tenant isolation
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
Acceptance criteria
- Seed generator produces synthetic entities matching declared schema constraints
- Relationships and edge cases are deterministic from a versioned seed
- No source connector for customer data exists in preview composition
Implementation constraints
- Do not claim synthetic distributions reproduce real customer behavior.
Verification to include
- Seed two previews with the same revision and compare logical fixtures.
- Attempt to configure an undeclared source connector and fail before data access.
Deliverables
- Synthetic preview seeder and schema-edge fixtures
Rollout and recovery
Review fixture usefulness separately from data-safety enforcement.
Value of the work
For the engineer: Practice ephemeral environment lifecycle, scoped configuration, cleanup, quotas, and provider reconciliation.
For the team: Review changes in isolated representative environments while controlling leakage, resource growth, and abandoned infrastructure.
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.
