Conversation
Port the response-queue-poisoning skill into the web-security capability. Covers CRLF-powered desync attacks: escalating HTTP header injection to response queue poisoning and request tunnelling. Chains with existing crlf-response-splitting, web-cache-deception-path, parser-differential-bypass, self-xss-escalation, and 403-bypass skills.

Three content changes landed on web-security since the 1.5.0 bump without a version bump: response-queue-poisoning skill (#116), tool-agnostic preflight guidance, and the pdtm preflight guard (CAP-1174). Re-publishing 1.5.0 with changed content 400s against dev (which already has 1.5.0 stored), failing the Sync Capabilities workflow. Bump to 1.6.0 so a fresh immutable version publishes cleanly across dev/staging/prod.
