Problem

E2E runs were failing with auth setup timeout even when no concurrent runs were present (PR#110 run #23500542756):

locator.click: Test timeout of 60000ms exceeded.
- waiting for getByRole('button', { name: /use a token/i })

Root cause: deploy-e2e-headlamp.sh used kubectl apply to update the Deployment/Service/ServiceAccount, but kubectl apply doesn't trigger a rollout if the pod spec is unchanged between runs. A degraded pod from a prior run (e.g., one that didn't tear down cleanly due to a cancelled or failed job) would keep serving in an inconsistent state. The fresh ConfigMap was mounted but the pod itself was stale.

Changes

`scripts/deploy-e2e-headlamp.sh`

Delete Deployment, Service, and ServiceAccount (with --wait) before applying new manifests. This guarantees a fresh pod on every run regardless of what was left behind by prior runs.

`e2e/auth.setup.ts`

Add explicit waitFor({ state: 'visible', timeout: 15_000 }) before the "use a token" button click. This causes failures to surface at 15 s with a clear locator message rather than silently timing out at the global 60 s limit — which made diagnosing the root cause harder.

Impact

Unblocks PR#110 (ci/e2e-concurrency-guard) — once this merges, PR#110 can rebase on main and its E2E run should pass cleanly.

QA Review Summary

PR #113 — E2E clean-deploy fix

Test Results

✅ All 100 unit tests pass
✅ TypeScript check passes
✅ CI pipeline passes
✅ E2E Tests pass (2m8s)

Changes Reviewed

1. e2e/auth.setup.ts (lines 45-52)

Added explicit waitFor({ state: 'visible', timeout: 15_000 }) before clicking the "use a token" button
Improves failure diagnosis: errors surface at 15s with a clear locator message instead of silently timing out at 60s
Good defensive coding

2. scripts/deploy-e2e-headlamp.sh (lines 61-69)

Deletes existing Deployment, Service, and ServiceAccount (with --wait) before applying new manifests
Guarantees a fresh pod regardless of prior state — fixes the root cause where kubectl apply only patches in-place and a degraded pod keeps serving
ConfigMap is properly deleted before creation (line 52-53), ensuring idempotent redeploy

Minor Observation

ServiceAccount deletion (line 69) lacks --wait flag unlike Deployment and Service. This is a minor inconsistency but ServiceAccount deletion is typically fast and shouldn't cause issues.

Verification

E2E Tests passed on this PR, validating the deploy/teardown cycle
This PR unblocks PR#110 () which depends on clean E2E infra

QA Approval: ✅ Approved

Clean fix. Root cause correctly identified — apply-without-delete leaves stale pods when the spec hasn't changed. Delete-before-apply with --ignore-not-found --wait is the right pattern. The explicit waitFor in auth.setup.ts is a good diagnostic improvement. Approved.

QA Review: PR #113

Tested: vitest (100 tests PASS), tsc (PASS)

Changes reviewed:

e2e/auth.setup.ts:48-52: Added explicit 15s wait before clicking "use a token" button. Good — surfaces failures at 15s instead of 60s.
scripts/deploy-e2e-headlamp.sh:61-67: Deletes existing Deployment, Service, ServiceAccount before applying new manifests. Fixes root cause: kubectl apply doesn't trigger rollout when pod spec is unchanged, leaving stale pods from prior runs.

Edge cases considered:

The --ignore-not-found flags handle first-run scenarios cleanly
The --wait flag ensures resources are fully removed before proceeding

Regression check: No existing behavior broken — this only affects E2E deployment script.

Verdict: QA APPROVED
