# =============================================================================

# Scoped test ServiceAccount + RBAC for the in-cluster Chainsaw conformance Job
|
|
# (ADR-0011; docs/14 "Where each layer runs"; R-SEC-02 least-privilege).
|
|
#
|
|
# SKELETON / PLACEHOLDER — RBAC is deliberately LEFT EMPTY here and authored
|
|
# least-privilege as each fault-injection capability actually lands (T-3.0+). The
|
|
# rule is: grant nothing until a committed test needs it, then grant exactly that
|
|
# verb/resource, with a comment naming the test that requires it. This SA is a
|
|
# PRIVILEGED TEST IDENTITY — it is its own audit item (R-SEC-02): it MUST NOT be
|
|
# reused by workloads, and every widening is reviewed.
|
|
#
|
|
# CI holds NO cluster credentials. CI only triggers the Job (T-6.1b via Gitea
|
|
# Actions); the Job runs under THIS ServiceAccount, so cluster access stays
|
|
# in-cluster and scoped (docs/14, R-SEC-02).
|
|
#
|
|
# Deployment: reconciled by Flux into the `conformance` namespace once the cluster
|
|
# exists (Phase 1+). Not applied in Phase 0 (no cluster).

Never reuse for workloads. Widen only alongside the test that needs it.
