# appliance lifecycle
Iridium Sprint 8 extends the appliance candidate with a narrow lifecycle and support-boundary packet.
This document packages the product-owned lifecycle inputs that sit beside the shared Alloy appliance workflow. It does not claim Rhodium acceleration ownership, Strontium certification ownership, or Palladium control-plane behavior.
## Generate lifecycle artifacts
Run:
```sh
python3 scripts/appliance_lifecycle_report.py --report-dir artifacts
```
This writes:
- `artifacts/appliance_lifecycle_report.json`
- `artifacts/appliance_lifecycle_report.md`
- `artifacts/appliance_lifecycle_handoff.json`
- `artifacts/appliance_lifecycle_handoff.md`
- `artifacts/appliance_support_snapshot.json`
## What the lifecycle report verifies
- the Sprint 7 flagship release gate is still green
- the Sprint 8 appliance profile gate is still green
- a staged appliance dataset can be reopened by the current release without changing query results
- a support snapshot is collected for the staged appliance lifecycle root
- the product support boundary is declared against the shared Alloy workflow
## Lifecycle packet contents
- upgrade continuity proof for the staged local appliance dataset
- backup/restore reference from the appliance profile artifact
- diagnostics manifest reference from the appliance profile artifact
- support snapshot for the lifecycle work dir
- support-boundary ownership map
