- Add USER_AWARENESS to the Verdict union in campaign-classifier.ts
- mapVerdictToActions('USER_AWARENESS') returns ['acknowledge_user']; not added to DESTRUCTIVE_ACTIONS so requires_approval computes false
- classifyCampaign's simulation branch now assigns verdict = 'USER_AWARENESS' directly instead of falling through to evaluateSpamVsUnwanted
- deriveDefaultParams('acknowledge_user') returns {} (no operator-editable params)
- Widen TriageNoteEvidence.verdict to admit 'USER_AWARENESS' (pure type widen, no formatting change)
- Tests: classifier simulation fixtures now assert USER_AWARENESS/acknowledge_user/requiresApproval=false; new mapVerdictToActions/computeRequiresApproval/deriveDefaultParams cases
- formatTriageNote renders verdict/confidence/summary/reasons/blast-radius
(both branches)/recommended actions/current remediation state as prose
- Routes indicator URLs through sanitizeUrl and the whole assembled output
through sanitizeNoteText before returning
- Handles null verdict/confidence gracefully
- Exports TriageNoteEvidence interface for Plan 02
- All 9 formatter tests pass
