e2e: the whole grant for an S3 bucket (skipped — blocked on hq issue 010)
Mirrors the postgres bed for minio: a provider (runtime carries mc) + a consumer requiring s3-bucket, proving the consumer reaches its bucket with the access key and secret the mesh delivered. It surfaced a real limit: the mesh derives `as` = mesh_<node>_<module> (22 chars), and an S3 access key is capped at 20, so minio refuses the service account. The test is correct and skipped pending 04-ISSUES/010, not worked around. Claude-Session: https://claude.ai/code/session_01LrgweAeERJYBg88c5cKDzF

|

|
* The postgres bed proves the provider/consumer contract for a database. This proves it for object

* storage, on a provider whose code drives the `mc` CLI (so the runtime image carries it): minio is
|

|
||||||
|
* a copy to each end. minio's provisioner — reading only the mesh's contributions — creates a bucket
|
||||||
|
* and a service account under the access key the mesh derived, with the secret it minted. The proof is
|
||||||
|
* the consumer reaching its bucket with the access key and secret the mesh delivered it. Nothing is
|
||||||
|
* placed by the test.
