Noisy Errors

Expected Findings

• Bootstrap requests return 500, 503, 404, and malformed JSON.
• Page emits multiple console.error and console.warn lines on load.
• A JS exception is thrown and caught during boot.
• Page renders despite all errors. Scanners that crash, hang, or emit findings here are misbehaving.

Primary Flows

• 500 endpoint Always 500
• 503 endpoint Service unavailable, Retry-After
• 404 endpoint Not found
• Malformed JSON Truncated JSON body
• Slow endpoint Delayed response

Signals

console.error("[boot] failed to load shared config")

Notes

• Pair this with ref0 to measure precision: a scanner that stays clean on both is well-calibrated.
