Fluxtion compiler diagnostics

Every diagnostic the compiler emits carries a stable code and a documentationUrl pointing at one of these pages.

code	severity	what it means
FLX-1001	ERROR	Constructor parameters must correspond to mapped fields, in order.
FLX-1002	ERROR	An @ExportService method must return void, or boolean to control propagation.
FLX-1005	ERROR	Every node has a unique name in the generated processor.
FLX-1007	ERROR	The dependency graph must be acyclic.
FLX-1008	WARN	A graph with audit-capable nodes and no event audit records nothing they log.
FLX-1009	ERROR	Every constructor-mapped field must be accepted by a constructor, or explicitly excluded from generated-source reproduction.
FLX-1021	ERROR	Checked-in generated source must be regenerated when the graph model changes.
SPRING_BEAN_NOT_SELECTED	WARN	With a nodeBeans allowlist in force, a bean that is neither listed nor ignored is excluded from the graph.
SPRING_CONFIG_LOG_LEVEL_CONFLICT	ERROR	Every FluxtionSpringConfig that declares a non-null logLevel must declare the same one.
SPRING_HANDLER_MISMATCH	ERROR	An event-handler binding must name a node whose handler surface accepts the declared event type.
SPRING_RECONCILE_CONFLICT	ERROR	Reconciliation must preserve developer-owned source and refuse conflicting edits.
SPRING_RECONCILE_WRONG_CONSTRUCT	ERROR	@ExportService annotates an implemented interface use, not the class declaration.
SPRING_UNDECLARED_SERVICE_CALLBACK	ERROR	Under strictServiceBindings every service callback a selected node registers must be declared in the Spring configuration.

Scope, and the "it worked yesterday" report

Fluxtion builds a graph three ways — interpreted, in-process and AOT. Some rejections belong only to rendering a node as Java source, so an AOT build asks one question the others do not: can this node be written out? A graph developed interpreted can therefore meet a rejection for the first time at AOT build. Each page states its own scope.

These pages are generated from the compiler's own diagnostics, so each one shows exactly the text a build emits.
