+# Debug diagnostics and right-wrist correction — 2026-09-24
+
+Historical observation, not current availability or permission to run tests.
+
+The wearer clarified that the right-wrist panel faced away (its back was visible).
+Commit `29f3729d` reverses right-wrist panel-right and panel-front, preserving
+panel-up, center and size. Offline pose tests check both hands, orthonormality
+and positive determinant over several rolls; this is not physical acceptance.
+
+The wearer also reported repeated generic transcription failures. The retained
+app log contained startup status only. Inspection found that the Python worker
+replaced every request exception with `transcription failed`, and both the native
+parent and Python suppressed stderr. No underlying exception had been retained;
+the root cause therefore remained unknown. The user declined a public-clip
+inference trial and chose to retry speech themselves after diagnostics were added.
+
+Commit `6592e1af` adds default-safe stage/category errors and explicitly opt-in
+advanced debugging through config/Settings. Full worker stdout/stderr, tracebacks
+and transcripts may appear in private bounded logs when enabled; no raw clip
+archive is created. The native receiver allowlists error labels before showing
+or logging the non-debug error. Settings changes restart the owned worker and
+discard current work; defaults remain off. See [diagnostic policy](../worker.md#advanced-debugging).
+
+## Checks and deployment
+
+- Local default CTest: 13/13; local native hardware-free CTest: 16/16.
+- Inspected a synthetic Settings canvas containing the toggle and privacy warning.
+- ARM64 native build from Git archive `6592e1af`: hardware-free CTest 16/16.
+  Includes fake-child stderr/protocol isolation, log bounds/rotation/permissions,
+  unsafe path refusal, opt-in/off behavior and safe-error privacy tests.
+- Installed version: `2026-09-24T190806Z-g6592e1af`.
+- Native-only archive SHA-256:
+  `eac25ae6e36970301e5cb67614eaa4053d20b79711397b462e2caf1359c09709`.
+- Checksum-verified installer selected the version above; installed `--version`
+  and the restarted process's executable path matched. Previous version retained:
+  `2026-09-24T184918Z-g7a3a5451`. The intermediate wrist-only archive was not installed.
+- Runtime/model paths configuration hash unchanged. Installer backed up the
+  previous config, added `advanced_debug: false`, and retained normal priority,
+  approved X/B/A/Y mappings and the wrist size/offset settings.
+- The saved mount was now `left-wrist` (changed since the earlier right-wrist
+  observation); installation preserved it rather than choosing for the wearer.
+- No FrameYap process was present immediately before this install. Relaunched
+  only FrameYap. No SteamVR/SSH/user-session process was stopped. Startup reported
+  normal priority and Lasers anytime off; this does not establish panel visibility.
+
+No public-fixture inference, assistant-triggered microphone recording or input
+injection was performed. Normal authorized app startup warms the configured worker
+and opens/discards idle microphone samples. Advanced logging was left **off** for
+the wearer to enable. Actual failure diagnosis, Settings-toggle behavior on Frame,
+and physical wrist acceptance still require the user's next trial.
