The metadata provider that built this Info object, when known.
Info getters that resolve sibling metadata (an entity's IS-A children, a permission's RLS
filter, a query's fields, an authorization's roles, …) must read from the SAME provider the
object came from. In a multi-provider process — several GraphQLDataProvider instances with
separateConnection, or a server servicing several connections — the global
Metadata.Provider is a different provider or not set at all. Providers pass themselves to
every Info constructor (new m.class(row, provider)), and container Info objects hand it to
the child Info objects they construct.
undefined for an Info object built outside a provider (tests, ad-hoc construction). Callers
then fall back to the global provider, which is exactly the pre-existing behavior.
Gets the parsed validation filters for this parameter. Parses the JSON string of filter definitions into an array of filter objects.
Array of parsed filter definitions, or empty array if parsing fails
ProtectedcopyCopies initialization data from a plain object to the class instance. Only copies properties that already exist on the class to prevent creating new fields. Special handling for DefaultValue fields to extract actual values from SQL Server syntax.

Records the provider that owns this Info object. A null/undefined provider is ignored, so passing an optional constructor argument straight through is always safe.

Default JSON serialization for BaseInfo subclasses.
Emits all non-underscored direct field declarations. For _-prefixed private backing fields
(the MJ pattern for collection storage — e.g. _Fields, _RelatedEntities, _OrganicKeys),
emits the value of the corresponding same-named public getter instead. Purely computed getters
without a backing field (display-name formatters, derived flags) are intentionally skipped —
they can throw when source fields are null and don't belong on the wire anyway.
A _-backed getter that throws is omitted from the output rather than aborting the whole
serialization. That omission is safe ONLY because such getters are recomputable: the backing
field is a lazy cache over other serialized state (e.g. QueryInfo.CategoryPath over CategoryID),
so the value is rebuilt on the next access after a warm boot. Do not add a _-backed getter
whose value cannot be recomputed from the serialized fields — a throw would silently drop it.
Nested BaseInfo instances and arrays of them unwrap automatically via JSON.stringify's native toJSON() protocol.
Subclasses may override to emit a filtered subset or custom shape (see EntityFieldValueInfo).
Stores parameter definitions for parameterized queries that use Nunjucks templates. Each parameter represents a dynamic value that can be passed when executing the query. Parameters are automatically extracted from the query template by the MJQueryEntityServer using LLM analysis, or can be manually defined. The combination of parameter metadata and validation filters creates a self-documenting, type-safe query execution system.
