- DataClassification (PUBLIC < CONFIDENTIAL < PII < PHI): a qbit
stand-in for core's (QRun-IO/qqq#1142) behind a pluggable
ClassificationSource (config by default; core metadata or
qbit-secured-data overrides later).
- Each turn tracks the highest classification its page context, history
and tool results touched (turn.classification, conversation
max_classification, never lowered).
- PhiRoutingGuard before EVERY model call: PHI only to hipaa_eligible
provider rows; otherwise the turn ends PHI_BLOCKED with the reason and
the tool results are never sent.
- HIPAA mode: no non-eligible providers (resolve, enable, code fallback),
AES-256-GCM conversation storage (key by env-var reference, required),
PHI retention period, no provider messages or stack traces in logs.
- assistant_data_audit: one row per model call that carried PII/PHI and
per block (who, classification, tables, provider, model, decision).
- System rule 11: masked values stay masked; never ask to reveal them.
