Root cause of the recurring "just test-all shows 27/16, playwright alone
shows 43/0" split:
Justfile loads .env with dotenv-load, which sets PUBLIC_APP_URL to the
LAN IP from the phone-preview config. playwright.config.ts was reading
that env and using it as baseURL. The resulting LAN-IP OAuth round-trip
(browser → GoTrue → Keycloak → browser) adds ~hundreds of ms of
loopback routing per hop and pushes the $currentCollective hydration
past Playwright's first synthetic keystroke, producing a silent early
return in handleAdd (name typed but Enter never triggers a write).
Running playwright directly skipped dotenv-load, baseURL fell back to
localhost, and everything passed. Same code, same machine, different
wrapper.
Fix
apps/web/playwright.config.ts: baseURL hardcoded to 'http://localhost:5173'.
The LAN IP stays in PUBLIC_APP_URL for on-device phone previews (step
2/3 of the mobile-testing recipe in CLAUDE.md), but e2e always hits
the loopback so the timing profile is deterministic.
apps/web/tests/fixtures/login.ts: origin-check hardcoded to localhost
to match.
Verification
just test-all → exit 0, 228 tests green (34 pgTAP + 140 Vitest
integration + 11 Vitest unit + 43 Playwright), 4 skipped (upstream
Realtime presence + WebKit-only touch gestures).
just test-e2e alone → 43 passed.
pnpm exec playwright test alone → 43 passed.
