# A strategy CRD that inlines the upstream pod schema adds about 600 KB, and
# backupstrategy-controller stores each CRD twice in every Helm release
# revision, inside one Secret capped at 1 MiB. Three of them did once, and the
# upgrade that renders the default strategies failed with "Too long". Pod
# templates in api/backups/strategy are therefore Schemaless with
# PreserveUnknownFields (see the package doc there). hack/helm-release-size.bats
# catches the total; this names the field that caused it.
#
# Harness compatibility note: CI runs this file under Bats through
# `make bats-unit-tests`. It also remains compatible with the narrower legacy
# `hack/cozytest.sh` translator, so it avoids `run`, `$status`, `$output`,
# `skip`, and setup()/teardown(). Paths stay repo-root-relative for both
# runners.
#
# Run with: bats hack/strategy-crd-schemaless.bats
