# CASAN Plan-14 — RBAC decision audit into an H5-style oversight log.
|
|
#
|
|
# Every RBAC allow/deny decision is recorded (opt-in via CASAN_RBAC_AUDIT_LOG) so a
|
|
# reviewer / RAI report / Control Plane can see who was allowed or denied what and
|
|
# why. Proves:
|
|
# * an ALLOW decision is logged with verdict + role + action,
|
|
# * a DENY decision is appended (append-only) with its reason,
|
|
# * a cross-tenant DENY records the tenant-boundary reason,
|
|
# * with no audit-log env set, nothing is written (backward compatible).
|
|
#
|
|
# Deterministic; hermetic; no model/network.
