+### 1.1, and what it turned out to be
+
+*Done 2026-08-31. Worth recording because the task was not the one written down.*
+
+**The control plane special-cases nothing.** `provides`, `requires`, `contributes` and `grants`
+are name-agnostic — asking for a bucket needed no change to the mesh at all. What was missing was
+a provider, and the last step where something on the machine turns a delivered secret into a key
+that works. So "add an object-store provision" was never mesh work.
+
+The provision is `s3-bucket`: a consumer's code is written against the S3 API and swapping one
+store for another does not break it, so by
+[ADR 0027](../../02-DECISIONS/0027-a-provision-names-what-the-consumer-is-coupled-to.md) the name
+says the protocol. A database is the other case, and names the engine.
+
+**One assertion here that a database does not need.** One PostgreSQL server holds separate
+databases and the product enforces the boundary; one object store holds every bucket behind one
+endpoint, so *a consumer cannot reach another consumer's bucket* is a policy somebody wrote — and
+a policy granting everything would pass every other test. **What is asserted is what the policy
+does not say.**
