Infrastructure: Add Storybook end-to-end test pipelines #4256

Goal

Deliver native end-to-end Storybook pull-request pipelines for macOS, Windows Fabric, and Win32 Paper through one supported workflow. Parent: #4275.

Status - 2026-10-01

Completed pipeline-delivery milestone. Production qualification, operations, reliability, and required promotion remain open in #4349. The all-skipped reporting bug discovered during reconciliation is #4342.

Delivered

• All three desktop PR jobs build/verify/diagnose source-built native helpers and pin subsequent resolution to verified artifacts.
• The shared stories-and-tests lifecycle traverses the native catalog and runs component-authored tests against the exact owned native app, not a fake fallback.
• Named, typed WDIO callbacks execute with correlated readiness, source/manifest identity, fresh per-case preview/session/worker, and ownership-safe cleanup.
• Native build logs, doctor reports, run artifacts, and command diagnostics are uploaded with if: always().
• The authored cohort extends beyond Button: current discovery is 29 cases across 17 stories and ten component/primitive families per endpoint.
• Hosted input restrictions are explicit. Windows/Win32 disable keyboard, physical click, and wheel; macOS disables physical click.

Delivery evidence: PRs #4294, #4306, #4313, #4314, #4320, and #4321. All three Storybook jobs passed in run 36927750317, each with 7 authored passes / 22 capability/state skips.

What closure does not mean

The pipelines are not qualified required interactive gates. Main currently requires only PR, whose aggregate excludes Storybook and bundle-size jobs. Matching portablePlanDigest also does not prove WDIO equivalence: it hashes legacy static plans, and the component catalog now uses callbacks.

The original later-stage acceptance criteria are preserved in #4349: authoritative environments, callback/catalog identity, complete active-run reporting, retry/quarantine policy, named artifact/runner owners, a measured reliability window, restored regression/accessibility cohorts, and required-status promotion.

Bugs and related follow-ups

• Infrastructure: Reject all-skipped WDIO runs as completed coverage #4342: a selected all-skipped WDIO run currently reports passed; retained Windows/Win32 Checkbox reports reproduce this.
• Infrastructure: Restore Storybook stories excluded by native desktop crashes #4344: native host crashes exclude Accordion/Callout on Fabric and Accordion/ListItem on Paper.
• Infrastructure: Restore Windows Storybook focus-regression parity #4347 / Infrastructure: Complete portable Storybook accessibility coverage and reporting #4343: complete original focus-regression parity and accessibility coverage.
• Infrastructure: Complete Desktop Driver production release qualification #4345 / Infrastructure: Qualify Windows/Win32 capture fidelity and provenance #4348: driver release and qualified capture/provenance.
• Infrastructure: Add native Storybook visual comparison reports for Windows, Win32, and macOS #4328: native baseline/candidate/diff reports remain unimplemented. Pixel differences stay advisory.
