# GREE Controller v0.4.3 - build and validation report

## Scope

Version 0.4.3 restores the classic rounded GREE Controller UI while keeping the neutral light/dark palette and green accents introduced in the previous release. It also removes three Rust dead-code warnings reported by the LXC release build.

## UI changes

- Restored the classic large rounded cards and panels.
- Restored circular thermostat +/- and power controls.
- Restored compact desktop navigation and five-item mobile bottom navigation.
- Kept the v0.4.2 climate-history functionality and multi-series charts.
- Kept neutral dark/light surfaces.
- Dark accent: `#3ecf8e`.
- Light accent: `#24b47e`.
- UI is plain committed CSS in `web/styles.css`; no frontend package manager or CSS build step is used.
- Theme-aware scrollbars remain enabled and compact horizontal control scrollbars remain hidden.

## Rust warning cleanup

Removed code that was superseded by bucketed zone history:

- `Db::list_zone_readings`
- `queries::LIST_ZONE_READINGS_BY_ZONE`
- `queries::LIST_ZONE_READINGS_ALL`

The active history path is `Db::list_zone_history` with the bucketed SQL queries.

## Validation performed in packaging environment

- HTML structure sanity checks.
- JavaScript syntax check with Node's parser only; Node is not part of the application/runtime.
- JSON validation for language files and HA manifest.
- Shell syntax checks for `scripts/*.sh`.
- Python syntax check for migration helper.
- Verified no `list_zone_readings` or `LIST_ZONE_READINGS_*` references remain.
- Verified no frontend build/package files are required.
- ZIP integrity test and SHA-256 manifest generation.

A Rust toolchain is not available in the packaging environment, so the authoritative Rust tests and warning check run on the LXC through `scripts/update.sh` before installation.

Expected LXC validation:

```bash
cargo test --all-targets
cargo build --release
```

The three warnings supplied from v0.4.2 have been removed at source rather than suppressed.
