load app config: %w

Error message

load app config: %w

What it means

loadLLMRuntime reads the application config from defaultConfigPath() via LoadAppConfig and wraps failures as `load app config: %w`. A missing config file is tolerated (appCfg may be nil and defaults apply), so this error means the file exists but is invalid or unreadable — bad syntax, unknown fields, wrong types.

Solutions

1. Fix the syntax/type error at the reported line in the config file
2. Temporarily move the config aside to confirm it is the cause, then re-add settings incrementally
3. Fix permissions on the config file and its parent directory
4. Regenerate a fresh default config and re-apply your settings

Example fix

// before (~/.config/ocr/config.json)
{ "language": "en", }   // trailing comma
// after
{ "language": "en" }

data, err := os.ReadFile(cfgPath)
if err != nil {
	return err
}
var raw map[string]any
if err := json.Unmarshal(data, &raw); err != nil {
	return fmt.Errorf("config %s is not valid JSON: %w", cfgPath, err)
}

if err != nil {
	// config exists but is broken; move it aside and start from defaults
	os.Rename(cfgPath, cfgPath+".bak")
	return retryWithDefaults()
}

When it happens

Trigger: ocr review/scan startup when the user's config file (at the default config path) exists but fails to parse or validate; file unreadable due to permissions; hand-edited JSON/YAML with a syntax error.

Common situations: Manual edits leaving a trailing comma or wrong indentation; a `language` value of the wrong type; config written by another tool version with an incompatible field; file locked or owned by another user.
