Completes "no self-training": unconfirmed auto-applied character tags no longer seed CCIP references — character_references + the prototype builder (_current_fingerprints/_rebuild_one) gain a shared _positive_char_tag filter (human-applied OR operator-confirmed), mirroring the head-positive exclusion. Confirming a tag also has to move the change-detectors, or an incremental refresh/Retrain right after a confirm wouldn't fold the tag in (only the nightly full pass would): the CCIP global gate now counts character confirmations, and the head training fingerprint counts confirmations. Test for the CCIP path. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01CDgx8bQS5YrGRK76v8HUnM
