Locked design for wave 1 of cluster security hardening. Plan only — implementation lives in beads code-8ywc and follow-up commits. Captures: - security.md: Kyverno policy table updated (Audit → Enforce planned for the four security policies with the 31-namespace exclude list). New section "Audit Logging & Anomaly Detection" detailing the K8s API audit policy, Vault audit device + X-Forwarded-For trust, source-IP anomaly rules (K9, V7, S1), and the rejected-canary-tokens / rejected-K1 rationales. New section "NetworkPolicy Default-Deny Egress" describing the observe-then-enforce (γ) approach for tier 3+4. - monitoring.md: new "Security Alerts (Wave 1)" section listing the 16 rules (K2-K9, V1-V7, S1) and the Loki ruler → Alertmanager → #security routing path. - runbooks/security-incident.md (new): per-alert response playbook with LogQL queries, action steps, false-positive triage, and SEV1 escalation. - .claude/CLAUDE.md: new "Security Posture" section summarising the locked decisions: identity allowlist is me@viktorbarzin.me ONLY, source-IP allowlist CIDRs, no public-IP access policy, rationale for not adopting canary tokens.
