    # users.onboarded column. See tests/test_v29_home_migration.py for
    # the exhaustive coverage of that step.

    # v30 → v31: session-pipeline framework — session_processor_state
    #            replaces session_extraction_state with composite PK.
    # v31 → v32 (PR #233): flea-market upload guardrails — adds
    #            store_entities.visibility_status + creates store_submissions.
    # v32 → v33 (PR #233): forensic columns on store_submissions —

    #            persist-blocked-bundle behavior so admins can Rescan /
    #            Override / Download; 30-day TTL purge clears bytes while
    #            keeping the row + sha intact. See docs/STORE_GUARDRAILS.md.
    # v33 → v34: drop store_submissions.retry_count — counter mixed LLM
    #            error count + admin rescan count, redundant with audit_log.
    # v34 → v35 (PR #233): store_entities gains 'archived' visibility
