- PLAN.md: new Stage 17 "Test-contour verification & defect fixes" (exercise the deployed contour end-to-end and fix what it surfaces — connector liveness check, path-conditional CI); the former prod-deploy stage becomes Stage 18. - Renumber every "Stage 17" prod-deploy reference to "Stage 18" across docs, compose, Caddyfile, ci.yaml and CLAUDE.md; the post-Stage-14 split range is now "Stages 15–18".
