+Ebean can map `@DbJson` and `@DbJsonB` properties in two ways:

 - **Built-in** JSON support, backed by **avaje-json-core** — no extra dependency.

- **Avaje Jsonb**, provided by **`ebean-avajejsonb-mapper`** and its generated adapters.
+- **Jackson `ObjectMapper`**, provided by the **`ebean-jackson-mapper`** module — used
+  for everything the built-in support does not handle.

-The built-in mapper handles the common natural JSON types. Add one mapper module for
-typed collections, POJOs, records, and other custom types.
+This guide lists exactly which property types are handled built-in and which require
+`ebean-jackson-mapper`.

-> If a property type is **not** handled built-in and no mapper module is on the classpath,
-> Ebean fails fast at startup:

 If the caller needs multiple to-many paths or a paged query, be suspicious of a
 plain `fetch(...)` on those paths. `fetchQuery()` is often the safer default.

-### `@OneToOne(mappedBy=...)` is EAGER by default — mark it LAZY
-
-The non-owning side of a `@OneToOne` (the side with `mappedBy`) defaults to
-`FetchType.EAGER` per JPA, same as `@ManyToOne`. Unlike a `@ManyToOne`
-reference (which is FK-only until `.fetch()`'d), Ebean's default select for an
-EAGER `@OneToOne(mappedBy=...)` still adds a `left join` to the target table
-on **every** query for the owning entity — even a plain `findById()` — because
-there is no local FK column to use as a lazy reference; the only way to know
-the associated row exists is to join to it.
-
-If that association is rarely needed (e.g. a rarely-read child/detail table),
-this join executes on every load of the parent, including in hot-path list
-queries, and can dominate query cost as more such associations accumulate.
-
-**Always set `fetch = FetchType.LAZY` on `@OneToOne(mappedBy=...)`
-associations unless the association is genuinely needed on (almost) every
-load:**
-
-```java
-@OneToOne(mappedBy = "device", fetch = FetchType.LAZY)
-private SensorBoard sensorBoard;
-```
-
-This correctly excludes the join from Ebean's default select clause (verified
-for FK-based, non-shared-primary-key `@OneToOne` relationships — the common
-case). Callers that do need the association can still `.fetch("sensorBoard")`
-explicitly on the query bean.
-
-**Caveat:** the exclusion is driven by Ebean's default-select-clause
-mechanism. It is bypassed if the query has already been switched into an
-"all properties" mode by something other than the deploy-time
-`FetchType.LAZY`/`EAGER` metadata (for example, an active AutoTune profile
-that supplies its own tuned property set). Confirm the join is actually gone
-by checking generated SQL (`LoggedSql` in tests, or query logging) after
-making this change — don't assume it's excluded from the annotation alone.
-
-### Agent rule
-
-Default new `@OneToOne(mappedBy=...)` fields to `fetch = FetchType.LAZY`
-unless there's a clear reason the association is needed on every load. This
-is a one-line, low-risk change that avoids an always-on join.
