The deployment injects CLAUDE_INGEST_CLIENT_BLOCK as a bare alternation of client names; claudewatcher compiles it as (?i)\b(...)\b. The raw/ router used it raw, so a short client name would match inside ordinary words and park clips that have nothing to do with the client. INGEST_CLIENT_BLOCK stays a full regexp, used as is. Mutation-checked. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
