Scope

• Preserve upstream P0: enforce shared IEC 61850-9-3 PTP SOURCE profile before START; truthful toggle #265 SOURCE IEC 61850-9-3 profile contract and firmware source_reason classifications.
• Repair actual Timing Copy Diagnostics failure: PtpExpertPanel.qml imported no ARStack.Studio module for its StudioClipboard singleton. Add explicit module import, boolean copy result with host clipboard readback, truthful feedback, and full selectable diagnostics fallback.
• Introduce bounded PTP SHOW / STOPPED preflight before PROFILE PTPROLE + CONFIG + START. Prevent serial rejection due to stale Studio OFF state while firmware remains RUNNING, without automatic STOP or blind retry.
• Surface exact transaction phase and raw board rejection in diagnostics; retain same-boot error across safety STOP.
• Add Windows --check-clipboard mode, static QML/SSOT regression, and deterministic positive/negative PTP preflight tests. Run clipboard probes against real Windows GUI and installed Inno preview.

Validation

Review and CI are required before this branch is packaged for operator verification. Hardware START remains to be checked with exact bundled ESP32-P4 firmware; never claim remote board changed from source edits alone.

Stack

PR based on #265, itself stacked on #264/#262; not on historical main. Avoid merging into main alone before upstream stacked changes.

Keep the diagnostics snapshot reactive

While the dialog remains open, this binding has no dependency on device.logTextChanged, PTP state changes, or the other signals that affect diagnosticsText(); QML cannot observe property reads performed inside the C++ invokable. Consequently, incoming diagnostics never appear, the Clear button leaves the old log visible, and the manual clipboard fallback can show a stale snapshot until the dialog is closed and reopened. Expose the snapshot as a notified property or explicitly bind/recompute it from the relevant change signals.
