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.
