## Description
|
|
|
|
When `format = "json"` is configured but no `log_file_path` is set, the `None`
|
|
branch of `init_json` creates a layer **without** calling `.json()`. The output
|
|
is plain text, not JSON. The `format = "json"` config value is silently ignored.
|
|
|
|
The spec (operations.md) states: "Both output destinations must respect the
|
|
`format` config value: when `format = "json"`, both file and stdout output must
|
|
use JSON formatting."
|
|
|
|
### Changes Required
|
|
|
|
**`src/logging/mod.rs`** — `init_json` function, `None` branch (lines 54-58):
|
|
- Add `.json()` to the stdout-only layer:
|
|
```rust
|
|
None => {
|
|
let layer = tracing_subscriber::fmt::layer()
|
|
.json()
|
|
.with_ansi(false)
|
|
.with_filter(env_filter);
|
|
tracing_subscriber::registry().with(layer).try_init()?;
|
|
}
|
|
```
|
|
|
|
## Acceptance Criteria
|
|
|
|
- [ ] `.json()` is called in the `None` branch of `init_json`
|
|
- [ ] `format = "json"` with no `log_file_path` produces JSON output on stdout
|
|
- [ ] `format = "json"` with `log_file_path` still produces JSON on both outputs
|
|
- [ ] `format = "text"` paths are unchanged
|
|
- [ ] `cargo test` passes
|
|
- [ ] `cargo clippy` passes with no warnings
