Silent Failure Review

Detection

ID	Pattern	Fix
SF1	catch (e) {}	catch (e) { logger.error(e); throw }
SF1	catch (e) { console.log(e) }	Show user feedback + log context
SF2	.then(fn) without .catch()	Add .catch() or use try/catch
SF2	async () => { await fn() }	Wrap in try/catch, handle error
SF3	No error UI states	Add error boundary, feedback component
SF4	value ?? defaultValue silently	Log when using fallback
SF4	data?.nested?.value	Check and report if unexpected null
SF5	catch { return defaultValue }	Log root cause before returning default
SF5	config.x || fallback	Validate config, warn on missing keys
