Summary

PRI-700: E2E was failing at the Install Playwright browsers step on ARC runners (both PR #57 and PR #58).

Root cause

The reusable workflow used npx playwright install --with-deps chromium directly, which is flaky on self-hosted ARC runners with intermittent network access.

Fixes

  • Playwright cache — caches ~/.cache/ms-playwright via actions/cache@v5, keyed on package.json hash. Cache hit skips download entirely.
  • Retry loop — 3-attempt retry with increasing delays (5s, 10s) for the install step.
  • PM-aware — respects pnpm vs npm detection from the existing Detect package manager step.

Preserves

  • All pnpm support from hugh/add-pnpm-support-plugin-e2e (corepack, cache, frozen lockfile)
  • e2e-namespace input added in that branch

The workflow was failing on pull_request_review events when triggered by
non-PR actors (e.g. greptile-apps[bot] commenting). The dual-approval job
would attempt to call the reusable workflow with a null PR number,
causing the reusable workflow to fail since there was no valid PR to check.

Changes:
- Guard the PR number with explicit null check: [ -z "${PR_NUMBER}" ] || [ "${PR_NUMBER}" = "null" ]
- Add validation of the reviews response before processing
- Fix jq filter to handle null pipeline values explicitly

Fixes flapping Dual Approval (CTO + QA) checks across all plugin repos.

…from real infra issues

This commit updates ci-health-check.sh to categorize CI failures:
- Code failures: test/lint/build failures on main → FAIL
- Infra failures: startup_failure, timed_out → FAIL
- Pending (process): action_required (awaiting review) → INFO only

action_required is no longer treated as a failure since it's an expected
process state (PRs awaiting dual approval).

PRI-700: E2E was failing at the Install Playwright browsers step on ARC
runners. Added:
- actions/cache@v5 to cache ~/.cache/ms-playwright
- Cache-hit check in Install Playwright step to skip download on cache hit
- 3-attempt retry loop with increasing delays (5s, 10s) for install
- Respects pnpm vs npm detection from prior step

Also preserves existing pnpm support from hugh/add-pnpm-support-plugin-e2e.

Updates reusable workflow ref to include Playwright cache + retry fix from
PR privilegedescalation/.github#145.

Co-Authored-By: Paperclip <noreply@paperclip.ing>
Uses the built-in cache-hit output from actions/cache@v5 instead of
manually checking directory existence. The 'if: cache-hit != true' guard
correctly skips the install step when the cache is warm.

UAT Review: APPROVED

Review type: Code-review UAT (CTO directive — no browser UI component)

What changed: plugin-e2e.yaml gains Playwright browser cache (keyed on package.json) with 3-attempt retry loop on install failure. Includes changes from PR #144 and #143.

UAT verification:

  • Playwright cache: actions/cache@v5 caches ~/.cache/ms-playwright ✅
  • Cache miss gating: correctly skips install when cache hit ✅
  • 3-attempt retry: exponential backoff pattern handles transient network failures ✅
  • Both npm and pnpm paths covered ✅

Acceptance criteria: Playwright browser install is cached and retried on failure. ✅

- Add required plugin-name input to plugin-e2e.yaml workflow_call
- Set PLUGIN_NAME env var from inputs.plugin-name in the e2e job
- Copy deploy-e2e-headlamp.sh and teardown-e2e-headlamp.sh to scripts/
  in the gh-repo (shared location for reusable workflow scripts)
- Scripts derive ConfigMap name from PLUGIN_NAME env var
- Scripts derive plugin mount path from PLUGIN_NAME env var
- Update headlamp-argocd-plugin e2e.yaml to pass plugin-name=headlamp-argocd
  and point to @main instead of @hugh/add-pnpm-support-plugin-e2e
