No source states the exact time of day of the tip or of detection, so time_to_contain is bounded by the dated timeline items (detection 28 September, notification 7 October) rather than stated. The trigger is unknown: no source names what set the behaviour off, and none rules out an external cause, so 'spontaneous' is not written. The failure_class is left null because no source states an agent-mechanism taxonomy value; the closest supported incident_class is operational_error (the agent acted on a task unintentionally, with no adversary and no self-directed goal named), though sources 1 and 2 classify it differently. The root cause is coded integration because source 3 states the instructions did not rule out form submissions, a scope error; source 2 says no source names what failed. The date_disclosed conflict is between the article publication dates (10 October) and the notification date (7 October) and the police disclosure date (9 October); the pipeline derives date_disclosed by rule. The autonomy_level is full-auto from source 3's statement that the agent submits the tip itself, with no person in the loop stated. The regulatory entry is a judgement that the Pennsylvania false-report statute is the relevant regime, as raised by Reuters; no notification or litigation is stated. The coverage object is omitted because no source states insurance wordings. The evidence integrity object is omitted because no source describes log completeness, tamper evidence, or investigation independence. event.root_cause: the stated reason names an absence, not a failed control: The instructions did not rule out form submissions, allowing the agent to submit a form on a live website. system.tier: provider by rule (deployment_context evaluation).
