t3-provision-users.sh now consumes roster_engine.py: derives accounts + per-tier groups + sticky ports + /etc/ttyd-user-map + dispatch.json from roster.yaml and applies them. ADDITIVE-ONLY for existing users (never strips a group, replaces a home, or re-locks an account) so the hourly timer is always safe. Best-effort tier validation vs live k8s_users: warns on a net-new absent user (emo), aborts only on a real tier conflict, skips when root has no Vault token. DRY_RUN mode for safe testing. Verified on the live host: reproduces dispatch.json content exactly, emo/anca groups + all t3-serve instances unchanged, idempotent, shellcheck-clean; deployed to /usr/local/bin (hourly timer target).
Engine: validate_tiers now returns ValidationIssue(severity) — error=conflict (abort) vs warn=absent (grant pending) — + has_blocking_errors(); 28 pytest cases. setup-devvm.sh redeploys the provisioner for reproducibility.

Pure functional core (PRD ViktorBarzin/infra#9 modules #1 roster engine + #5 offboarding diff) that the bash provisioner will consume as JSON: roster parse/validate, fail-loud tier-vs-k8s_users check, sticky-port + ttyd-map + dispatch derivation, additive-only group reconcile, and the staged offboarding diff (reversible cut vs gated userdel, never auto). 27 pytest cases, ruff-clean; no host I/O in the tested path. Verified to reproduce the live dispatch.json byte-for-byte from the real roster.
