Historical assistant message controls now reveal on article hover or keyboard focus, while current-message controls stay visible. The opt-in stylesheet reserves their layout space and tab access, keeps controls visible on narrow or hoverless devices, and disables the opacity transition for reduced motion.

Dogfood the behavior through the native example and an isolated installed-consumer fixture covering real Tab navigation, streaming, row reordering, layout/DOM identity, RTL and device media. Document the behavior while retaining the existing private API and in-progress T23 disposition.

Native verification also reproduced macOS filesystem notifications missing newly mirrored public directories. Enable Vite polling only on macOS; the final native suite uses the original development assertions and deadlines without diagnostic instrumentation.

Validation:

• React: 884 tests, type checks, lint, package builds, inventory and source/built boundary checks passed. Lint retains existing warnings.
• Retained installed proofs revalidated against final source, published package bytes, derived locks and physical dependency graphs: 16 ESM/type exports, 29 React and 27 Angular candidate scenarios, and four presentation profiles.
• Final native suite: 45/45 with two workers, zero failures/flaky/skipped; includes 11 production flows, React lifecycle, A2UI and installed-owner verification. Fresh manual walkthrough verified 7/7 fixture requests and closed the browser/server.
• Native proxy/mirror regressions: 63/63. Separate-process polling comparison: 14/14 asset trials; actual loaded config confirms macOS-only polling and disabled dotenv loading.
• API generation: 30 entrypoints, 749 symbols, no missing summaries; guide examples and generated agent context verified.
