 | 2026-09-02 | Passenger workbook header rejection and ERP-semantic compatibility | Root cause and repository fix verified; live attachment retry not performed | [Integration record](../30-worklog/tasks/20260902-merge-all-restart-b7e3c91f.md) | Source task `20260901-roster-header-error-a4f7` established that the approved workbook used the `身份证` alias and a safe reverse issue-date formula; normalizer `v1.3.0` accepts the exact mapped semantics without weakening workbook safety gates. |
 | 2026-09-02 | AgentBus employee/account/browser/ERP routing | Repository, release, and regression verified; migration/restart/extension rollout not performed | [Integration record](../30-worklog/tasks/20260902-integrate-all-push-c93a7f21.md) | Migration 018, immutable task assignees, channel-owner/route gates, one fresh matching worker, administrator non-execution, extension `0.5.164`, and release hashes were integrated and verified. |
 | 2026-09-02 | Leadership-dashboard filtering and summary interaction | Repository and focused regression verified; merged runtime not restarted | [Integration record](../30-worklog/tasks/20260902-integrate-all-push-c93a7f21.md) | Single-connection bounded reads, SQL prefiltering, selective hydration, 20-row paging, cancellation/timeout feedback, and display-only metric cards with explicit filters passed combined regression. |
+| 2026-09-02 | Native ERP product search for ordering forms | Root cause and live search-only behavior verified; repository/release verified; extension not reloaded | [Integration task](../30-worklog/tasks/20260902-integrate-product-search-3b7f6a20.md) | Both `plan_add.asp` and `orders_adds.asp` returned exactly one target product for the full keyword with radios left unchecked and no save; extension `0.5.165` now uses native non-empty search before its bounded empty-query fallback while retaining deterministic unique matching. |
