* test(#4658): add failing-first coverage for native frontend evidence
hasStaticFrontendEvidence recognised only JS-ecosystem evidence, so
computeUiPlanGate could never block for a SwiftUI/Compose/Flutter/XAML
project. Adds evidence-level fixtures for the four suggested markers
(import-matched for .swift/.kt/.dart, extension-alone for .xaml), the
reporter's non-UI Swift control case, marker-exactness and SKIP_DIRS and
I/O-degrade negatives, gate-level block assertions through makeProject's
new native frontendEvidence modes, and a pinned-seed fast-check property.
All new assertions are RED until src/ui-frontend-evidence.cts grows the
native branch.
* fix(#4658): give the ui plan gate's evidence check a native branch
hasStaticFrontendEvidence recognised only JS-ecosystem evidence (a root
package.json UI-framework dep, or a .tsx/.jsx/.vue/.svelte file), so
computeUiPlanGate could never block for a SwiftUI, Jetpack Compose, Flutter,
or .NET MAUI project — the #3312 gate was structurally unreachable for them.
Adds a native BFS over the same bounds and skip rules: .xaml is evidence by
extension alone (the .tsx analogue), while .swift/.kt/.dart count only when
their content carries the ecosystem's UI import marker (import SwiftUI /
import UIKit, androidx.compose, package:flutter) — matched on the import, not
the extension, so a non-UI Swift package stays silent exactly as the issue's
37-file control case requires. Marker reads are bounded to a 64 KiB prefix;
any I/O failure degrades to false per the module contract. The #3718
vocabulary filter, the JS evidence rules, and the weaker-extension exclusion
are untouched.
* chore(#4658): regenerate the macos conformance tier list
The native-evidence additions to tests/check-ui-plan-gate.test.cjs move the
file into the macOS conformance tier per the classifier; the committed
generated list is a derived artifact and must match the live tests/ tree
(the same sync the fragment-single-edit-propagation install test enforces).
* fix(#4658): accept both Dart quote styles and extract the shared bounded walk
The isolated reviews' remaining findings: the Dart marker carried only the
single-quote anchor, missing legal double-quoted imports (a spec-narrowing
deviation); the two evidence walks duplicated the subtle MAX_WALK_ENTRIES
cap semantics verbatim, so they are extracted into one walkProjectFiles BFS
with a visit callback; tests now use the createTempDir helper, shared
fixture literals that cannot drift from NATIVE_UI_CONTENT_MARKERS, a
double-quoted Flutter import case, and drop a vacuous assertion and a
mid-body re-require alias.
