# Functional chain driver: runs the ten functional suites in a fixed order
# (upgrade -> s3 -> kms -> tier -> storage -> heal -> pool -> security ->
# replication, with performance on its own runner in parallel) and guarantees
# the chain keeps moving even when individual suites fail.
#
# Each suite workflow can still be dispatched standalone (workflow_dispatch);
# only chain-triggered runs forward to the next suite via repository_dispatch,
# so a standalone run never drags the rest of the chain behind it.
#
# Why not workflow_run chaining: GitHub does not guarantee delivery of
# workflow_run events (they are fire-and-forget), and the head-SHA filter made
# newly added suites (storage) unable to trigger at all. Explicit
# repository_dispatch handoffs are verifiable and re-drivable.
