Vendor-neutral cache. Use when the real product is not in the catalogue; every rule for this kind still applies.

| ttlSeconds | integer | — | no | — |
| usedAsPrimaryStore | boolean | — | no | false |
Every rule whose selector covers this component's kind or its category. Whether a rule fires depends on the design: its properties, its edges and its groups.
cache-as-primary-store-without-persistence
This cache is the only copy of its data and has persistence turned off. A restart loses the data outright.
- — all of these hold:
- — the node's `usedAsPrimaryStore` is true
- — the node's `persistence` is false
cache-missing-eviction-policy
A cache with no declared eviction policy inherits whatever the vendor chose, and most vendors default to evicting nothing. The cache fills up and then starts refusing writes.
- — any of these hold:
- — the node's `evictionPolicy` has no value
- — the node's `evictionPolicy` is "none"
materialised-cache-without-rebuild-path
A cache holding materialised views has to be rebuildable from a durable store or a worker. With nothing feeding it, a cold cache is a permanent gap rather than a slow start.
- — all of these hold:
- — the node's `materialised` is true
- — this does not hold:
- — the node has at least one incoming edge from a sql-database, nosql-database, worker or stream
