Why

Keep app interaction in the browser through Interactor. The product ports had picked up driver-backed typing, clicks, taps and scrolling that duplicated local actions. This keeps the managed input surface limited to real keys for browser defaults and pointer movement for CSS hover.

Approach

Remove the overlapping actions from Interactor, app.native, the wire protocol, provider, types and capability flags. Scrolling composes through custom Interactor actions and real DOM scrolling. URL-only tests exercise those actions with native capabilities unavailable.

The ports exposed cross-document events/focus and contenteditable typing bugs in Interactor. Fix those upstream in Interactor #905, including paragraphs, caret placement and empty-line placeholders. Dyno pins the tested upstream commit; land and release that fix before moving back to a registry version. Git consumers need its standard prepare build enabled.

Managed contexts retain fractional pixel ratios, touch/viewport settings and user agents. Color scheme and external request blocking reset between tests. App requests preserve browser credentials, fill survives replaced controls, and startup cancellation preserves the run deadline.

Chromium keeps Playwright's default headless shell. Full Chromium on this Mac repeats content after 16,384 physical rows; affected macOS headed/branded/custom builds fail clearly above that limit. Real pixel checks cover long pages and fractional dimensions.

Project setup, fixtures and preparation now have a separate CI suite after the macOS Firefox execution job exhausted its five-minute budget. All 46 test files and every engine/OS combination remain covered; each job retains the same hard cap.

Evidence

The framework has 239 passing checks and two existing browser-specific skips, including installed-consumer types and URL-only interaction. All 17 WebKit capture checks and 20 supported native checks pass on Linux and macOS. Fractional bounds retain raw renderer pixels, including Linux's transparent partial row and anti-aliased corner. All seven documentation checks pass. The real Vizzly integration passes both workflows. Interactor has 136 passing browser tests and passing package/type builds.

Cyclonic retains 97 passing cases, three existing layout skips and 116 captures. BackChannel retains 31 workflows and 49 captures after replacing the overlapping actions. Visual baseline review remains open; no baselines were approved or replaced.
