Require non-empty data-slhx-sse values at build time and have the standard runtime reject cross-origin EventSource URLs with slhx:sse-error instead of opening an implicit external stream.
req: push/006

Treat empty static data-slhx-on lists and empty data-slhx-confirm messages as build errors, so authors do not silently disable dispatch or confirmation guards with blank attributes.

req: convention/004
req: diagnostics/002
Validate static data-slhx-on values against the runtime-supported delegated event set so generated EventName constants cannot imply browser behavior the runtime will never dispatch.

Reject invalid static data-slhx-policy and timing convention values at build time, so typos fail with author-facing guidance instead of silently falling back or disabling runtime behavior.

Fail fast when templates use misspelled or unsupported data-slhx-* attributes, with guidance to fix the spelling or use non-slhx data-* metadata for app-specific islands.
req: convention/009
req: diagnostics/002
Fail fast when templates invent selector-style data-slhx-target or data-slhx-select attributes, and point authors back to generated local slots instead of runtime selector semantics.

Generate ParamName constants for handle data parameters so public code can refer to checked param metadata instead of stringly typed names.
req: codegen/003
Generate ComponentRef constants for component-scoped APIs, include global component refs only when global_exports(true) is enabled, and document/use the checked component token.

Add techdemo coverage for #[slhx::form] plus #[slhx::handler] on the generated launch_work form, and ignore the internal __h hidden handle field in generated form metadata.

Add #[slhx::form] for user-authored form models, emit form field metadata into slhx.syms, and require form handlers to accept models that passed generated field compatibility checks.

Assert that slhx-build lowers Surface form controls into generated FormContract field metadata, including names, control kinds, required flags, and handle-to-form syms.

Use DOM-aware rendered-text inspection for the v0 shell marker check and extend unkeyed h-for validation coverage from slots to handles.

Discover data-slhx-on event names from hemplate Surface inputs and emit generated events modules plus symbol rows without adding runtime trigger semantics.

Emit handle_param facts for handled data-* attributes and reject handlers that omit generated param arguments. Cover the generated param boundary with unit and compile-fail tests.

Emit handle-form facts from slhx-build and have #[slhx::handler] reject generated form handlers that do not accept slhx::Form<_>. Cover the boundary with compile-fail fixtures.
