# 2026-07-05 22:40 Global Status Log Fix

## Problem

In fire_check-only mode, the global status monitor still printed values like:

```text
person:1 | temp:0.0°C | threshold value:70.0°C
```

Those fields belong to fire_leave/thermometry logic. When thermometry startup fails and fire_leave is disabled, these values are not active runtime measurements and should not be shown as real current data.

## Change

- Added latest fire_check result state in `main.go`:
  - `FireCheckHasResult`
  - `FireCheckLastNumber`
- Updated the fire_check result branch to record the latest detected fire target count.
- Updated `printGlobalDeviceStatus()`:
  - prints `fire:<value>` for fire_check target count;
  - prints `fire:null` before any fire_check result is received;
  - prints `person:null`, `temp:null`, and `threshold value:null` when fire_leave is disabled;
  - keeps `person/temp/threshold` only when fire_leave is active;
  - adds `fire_candidate`, `fire_last_seen_age`, and `fire_leave_enabled`.

## Expected Logs

Before any fire_check inference result is received:

```text
[1] DeviceUUID=xxx | fire:null | fire_candidate:false | fire_last_seen_age:null | fire_leave_enabled:false | person:null | temp:null | threshold value:null | cooling time:0s
```

After fire_check reports one fire target:

```text
[1] DeviceUUID=xxx | fire:1 | fire_candidate:true | fire_last_seen_age:500ms | fire_leave_enabled:false | person:null | temp:null | threshold value:null | cooling time:0s
```

If fire_check has reported a result but no fire target is present:

```text
[1] DeviceUUID=xxx | fire:0 | fire_candidate:false | fire_last_seen_age:null | fire_leave_enabled:false | person:null | temp:null | threshold value:null | cooling time:0s
```

## Impact

- Does not change fire_check alarm upload/report logic.
- Does not change heartbeat JSON format.
- Does not change inference startup arguments.
- Only changes runtime state tracking and global monitor log output.
- fire_leave logs remain available when fire_leave and thermometry are active.

## Verification

```text
gofmt -w main.go
go test ./...
go build -o bin/fireleave_tool.new .
```

The new binary was installed as:

```text
bin/fireleave_tool
