Initialize preview data from a synthetic schema contract
Preview startup depends on a copy of production data, making reviews slow and difficult to share safely.

Project context
A fictional team creates preview stacks for pull requests. Orphan databases consume resources and previews sometimes inherit settings intended for another branch.
Setup prerequisites
- Create a local provisioning adapter with synthetic repository events.
- Use isolated disposable resources and no production credentials.
Preceding work
Complete these dependencies, or supply their agreed outputs before taking this ticket.
- AENV-101 · Validate preview requests before allocating resources
- AENV-102 · Create a review-environment resource plan with an explicit quota
- AENV-103 · Keep preview connection material out of build output
- AENV-104 · Make preview creation resumable after a partial provider failure
- AENV-105 · Bind preview updates to the exact requested source revision
Acceptance criteria
- Create deterministic synthetic records covering declared UI states.
- Apply migrations before seeding the environment.
- Fail readiness when the seed contract is incomplete.
Implementation constraints
- Do not import real customer data or production secrets.
Verification to include
- Create two previews and compare declared synthetic identities and states.
- Fail a migration and verify the seed does not mark the environment ready.
Deliverables
- Synthetic seed command and readiness checks
Rollout and recovery
Enable the seed on new previews; recreate disposable data if the contract changes.
Value of the work
For the engineer: Practice resource lifecycle, reconciliation and least-privilege setup.
For the team: Review reliable preview workflows and accountable resource cleanup.
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.
