# Data Model — Legacy Purge (Runs / Routes / UI / Test Shims)

Date: 2026-02-14

This feature does not add or change canonical domain entities. It removes legacy artifacts and a legacy queued-job payload field.

## Entities (impacted)

### OperationRun

- Role: canonical run observability record for operational actions.
- Change: none.

### Backup scheduling job payload

- Role: queued execution of backup schedule work.
- Legacy field to purge: `backupScheduleRunId` (job payload / dispatch parameter).

#### Compatibility constraints

- Deploy A: The job MUST still deserialize when older payloads include `backupScheduleRunId`.
- Deploy B: Remove the field/property entirely after the compatibility window.

## UI artifacts (non-data)

- Redirect-only Inventory landing page: must be removed so Inventory entry points route directly to Inventory Items.
- Drift landing copy: change wording only.

## State transitions

- No new state transitions introduced.
