CYBER RUNBOOK TRAFFIC NOW TRACEABLE IN TELEMETRY

Pipeline agents and interactive sessions in defending-code now send attributable usage markers so runbook traffic is visible across your request logs.

The defending-code reference harness shipped a critical instrumentation change that makes agent traffic identifiable in Anthropic's telemetry pipeline [1]. Outbound API requests from pipeline agents now carry an `anthropic-cyber-runbook: pipeline` header plus a `cyber-runbook/<version>` User-Agent token, while interactive skill sessions get a header-only marker via `.claude/settings.json` [2]. The header was renamed to the `anthropic-*` convention before shipping to ensure gateway allowlists would honor it on passthrough [3]. This is infrastructure work that enables observability without breaking anything, but it matters if you're monitoring where your agent traffic goes. On the plugin side, both official and community plugin repos are cycling through routine dependency bumps across hyperframes, twilio-developer-kit, carta-investors, and a half-dozen others [4][5][6][7][8][9][10][11][12][13][14][15]. All bumps are pre-validated via `claude plugin validate` before the PR lands. Nothing is broken, nothing is urgent, but the backlog is moving.
