Escalated support case notes

Detects escalated support case notes: an escalated case / escalation notes / complaint escalation phrase combined with populated case structure - case or ticket numbers, labelled customer fields, priority/severity values or timestamped note entries. Phrase-only mentions (escalation procedures) stay discovery-only.

Type: regex
Engine: boost_regex
Confidence: medium
Confidence justification: Enforce tiers require populated case structure beside the escalation phrase; 'case notes', 'service request' and 'call center' were removed from the primary because they matched generic support text. Escalation procedures and news stay at 65. Medium because internal QA reviews of escalations share the structure.
Detection quality: Topic false positive

Known false positives

Escalation procedures, complaint-handling policies and training. Mitigation: No populated case structure, and guidance/training framing is excluded.
IT service-desk escalations about systems rather than customers. Mitigation: They can reach 75 through ticket numbers; they are usually lower sensitivity, so review in policy.
