+This table is intentionally conservative. Update it when draft work merges or live bench validation becomes available.
+
+| Surface | Public status | Safe claim |
+| --- | --- | --- |
+| `main` branch | Layered Tkinter desktop app with hardware-free tests, deterministic fixture demo, measurement export, operator guide, architecture notes, and safety notes. | Software engineering maturity for a lab-automation workflow; hardware-free validation only. |
+| [Draft PR #6](https://github.com/lishehao/auto-load-off-test/pull/6) | Draft capability/discovery/packaging sprint with public CI success on the PR head. Not merged into `main` yet. | In-review follow-up work for model capability profiles, mockable discovery/test-connect, and Windows packaging notes. |
+| [Draft PR #7](https://github.com/lishehao/auto-load-off-test/pull/7) | Draft calibration/export workflow receipt sprint stacked on PR #6. Main-target CI may not run until it is retargeted. Not merged into `main` yet. | In-review UI polish for reference coverage receipts, export artifact receipts, and non-modal workflow warnings. |
+| Live instruments | No current public evidence of live AWG/oscilloscope validation. | Do not claim live instrument validation; use the project as hardware-free software and workflow evidence. |

 ## Project Status
 
 The refactored app is local, single-process, and hardware-adapter based. Its strongest engineering signal is the separation between UI, use-case orchestration, pure domain logic, persistence, and instrument side effects.
+
+Current public validation is hardware-free: unit tests, mocked/fake instrument paths, deterministic fixture loading/replay, export round trips, and documentation checks. Live hardware validation remains future work and should not be claimed from this repository alone.
