Introduce prepared application templates (#641) - #673
Conversation
Consume builder registrations through `WireframeApp::prepare` so route middleware chains are built once and owned by an immutable `PreparedApp`. Retain deprecated builder-driven connection compatibility while the server continues evaluating its factory per connection. Add migration helpers and coverage for transform reuse, ordering, accessor retention, and the no-registration-after-preparation boundary.

Count builder factory and middleware transforms before preparation and after two prepared connections, documenting the baseline ownership behaviour for `#639` without changing server factory evaluation.

Sorry, something went wrong.
Record factory and middleware-transform counts for short-lived server connections before preparation, then prove prepared connections leave those counts unchanged. This provides the requested #639 baseline evidence without changing the server's deferred per-connection factory semantics.

There was a problem hiding this comment.
Deprecating the builder connection methods introduces a user-facing migration, but docs/users-guide.md still directs users to call WireframeApp::handle_connection and says that path caches middleware chains. Users following the guide will therefore adopt a deprecated API and miss the new required prepare().await/PreparedApp flow; update the guide alongside this deprecation.

There was a problem hiding this comment.
The new public prepare transition and PreparedApp methods have Rustdoc descriptions but no executable # Examples sections, leaving the central builder-to-runtime workflow undocumented at the API surface. Add clear examples showing preparation and repeated connection handling, as required for public function documentation.

In `@tests/ui/prepared_app_rejects_route.rs`:
- Around line 1-4: Add a module-level //! documentation comment describing the
purpose of the compile-fail UI fixture before the imports in
tests/ui/prepared_app_rejects_route.rs, then update
tests/ui/prepared_app_rejects_route.stderr so the diagnostic points to
prepared.route(1, handler) at line 15 and renders the corresponding source line

In `@wireframe_testing/src/helpers/drive.rs`:
- Around line 3-6: Remove the crate-level deprecated expectation and apply
narrowly scoped #[expect(deprecated, reason = "...")] attributes to each

Run on_disconnect before returning a stream-processing error.
core::process_stream can return Err through the framed.next() and handle_frame(...).await? paths. The current process_connection returns immediately, so setup state is dropped without calling on_disconnect. Capture the result, run teardown, then log and propagate the error. This gap also existed in the previous in-file pipeline, so treat this as a correctness fix rather than a regression.

Move the pure accessors out of the heavily bounded impl block.
protocol, protocol_hooks, and message_assembler only read fields. They do not need S: FrameMetadata<Frame = Envelope> or Envelope: DecodeWith<S> + EncodeWith<S>. Because they sit in this impl block, a caller whose serializer does not satisfy those bounds cannot call them at all. Place them in a second impl block that carries only the struct's own bounds.

Narrow the deprecation expectations to compatibility calls.
Apply each #[expect(deprecated, reason = "...")] only to the smallest helper or test that intentionally invokes the retained compatibility API. Avoid crate-, module-, or file-wide suppression so unrelated future deprecation diagnostics remain visible.
This applies to the compatibility helpers and tests in the listed additional locations.

Summary
This branch introduces an immutable
PreparedAppthat consumes aWireframeAppbuilder and transforms each route middleware chain once.Prepared connections borrow the direct route table, so subsequent connections
do not rebuild route services.
Closes #641.
The server deliberately retains its existing per-connection factory evaluation
semantics. Deprecated builder-driving wrappers preserve the current direct-test
path until the server-runtime slice adopts the prepared root.

make check-fmt: passedmake lint: passedmake typecheck: passedmake test: passedmake markdownlint: passedmake nixie: passedcargo test --doc: passedcoderabbit review --agent: completed with zero findingsNotes
The startup harness records the #639 baseline with two routes and two
middleware layers: two legacy TCP connections invoke the factory twice and
perform eight transforms; one preparation adds a single factory invocation and
four transforms; two prepared connections add neither.
PrepareErroris typed for future fallible middleware transforms. The currenttransition is infallible, so it cannot expose a partial prepared runtime.
