Refresh preview-auth verification branch from main

[Copilot]

Canonical issue

Linked by automation.

Outcome

This refreshes the preview-auth verification branch onto the current main line via merge commit so GitHub/Vercel emits a new preview check on the current head. The PR now revalidates the existing preview-auth gate against up-to-date branch state instead of a stale preview.

Scope

• Included:
  • Branch refresh — merged origin/main into copilot/trigger-vercel-preview-verification at 42e4f6c
  • Preview-gate continuity check — confirmed the PR E2E workflow still resolves PR-specific Vercel previews and fails closed when no preview is available
  • Regression coverage — reran the workflow tests that pin PR gate trigger coverage and preview lookup behavior
• Explicitly excluded:
  • Workflow logic changes — no .github/workflows/* behavior was modified
  • App/runtime changes — no frontend or backend product code changed
  • Production claims — this only refreshes the branch to trigger a new preview/auth verification cycle

Risk

• Risk level: low
• Failure mode: if the new preview or auth gate regresses, required PR checks should fail on 42e4f6c
• Rollback: revert merge commit 42e4f6c

Verification

List exact automated and manual checks, tied to the current head SHA.

• Focused tests
• Required CI
• Review threads resolved

Checks run on 42e4f6c:

• python -m pytest tests/unit/test_e2e_preview_workflow.py tests/unit/test_workflow_pr_gate_coverage.py -q --no-cov
• Manual: confirmed branch head published to origin/copilot/trigger-vercel-preview-verification and no local drift remained

Production evidence

Not yet applicable. This update exists to trigger a fresh Vercel preview/auth verification run on 42e4f6c; preview evidence should come from the newly spawned PR checks.

Agent handoff

• One canonical issue is linked
• No competing PR implements the same issue
• Acceptance criteria are satisfied
• Required checks pass on the current head
• Human decision is requested only for product, security, irreversible infrastructure, or production approval
