Validation: westside-admin#24 — cookie size fix

validation-24-2026-05-03 Doc

validation pass

Ticket

forgejo_admin/westside-admin#24 (PR #25, merged). P1 BUG: session cookie value (4719 B with id_token) exceeded browser per-cookie limit, causing infinite redirect loop. Fix: drop id_token from session payload.

Environment

  • URL: https://westside-admin.tail5b443a.ts.net
  • Cluster image SHA at validation: 63e708dc (post-#25 plus #27 azp fix)
  • Test user: draneylucas@gmail.com

Checks

# Criterion How to Verify Result Evidence
1 session cookie value &lt; 4096 bytes curl auth flow → capture Set-Cookie len PASS Live measurement: <strong>3151 bytes</strong> (was 4719 B pre-fix). 945-byte headroom.
2 browser keeps the cookie through the redirect chain Playwright headless Chromium SSO round-trip PASS Browser landed at /, page rendered <code>&lt;h1&gt;westside-admin&lt;/h1&gt;</code>. No redirect loop.
3 logout still works without id_token_hint POST /auth/logout, observe redirect to Keycloak SLO PASS Per <code>validation-16-2026-05-03</code> check #4 — Keycloak <code>/logout</code> redirect still fires; <code>id_token_hint</code> param omitted (acceptable per OIDC spec)
4 no regression on /auth/callback failure paths Static QA review of PR #25 PASS State validation, code exchange, error mapping unchanged

Verdict

PASS — bug no longer reproduces. SSO round-trip terminates cleanly.

Discovered Issues

Bug #26 (JWT aud=account vs expected westside-admin) was unmasked by this fix — the cookie-size loop hid it. Bug #26 was filed, fixed in PR #27, and validated in validation-26-2026-05-03 (or via the integrated validation in validation-15).
