Follow-up to the previous commit on this branch. Two additional fresh-clone
regressions surfaced during end-to-end verification, both affecting local
dev only and both landing inside the same SaaS-vs-local-dev seam:
### 1. Canvas 401-loops after first workspace creation
`GET /workspaces` is behind `AdminAuth` (router.go:121 — "C1: unauthenticated
workspace topology exposure"). The middleware has a Tier-1 fail-open branch
that only fires when *no* workspace tokens exist anywhere in the DB. The
moment a user creates their first workspace — via either the Canvas UI, the
API, or the e2e-api test suite — a token lands in the DB, Tier-1 closes, and
the Canvas (which has no bearer token in local dev: no WorkOS session, no
NEXT_PUBLIC_ADMIN_TOKEN baked in at build time) gets 401 on every list
call. The UI renders a stuck "API GET /workspaces: 401 admin auth required"
placeholder forever.
SaaS is unaffected because hosted provisioning always sets both
`ADMIN_TOKEN` and `MOLECULE_ENV=production`, and the Canvas there either
carries a WorkOS session cookie or `NEXT_PUBLIC_ADMIN_TOKEN` baked into
the JS bundle.
**Fix** (`workspace-server/internal/middleware/wsauth_middleware.go`): add
a narrow Tier-1b escape hatch that stays fail-open when *both*
`ADMIN_TOKEN` is unset *and* `MOLECULE_ENV` is explicitly a dev mode
("development" / "dev"). Production never hits it (SaaS sets
`MOLECULE_ENV=production`). Mirrors the existing convention in
`handlers/admin_test_token.go` which gates the e2e test-token endpoint on
`MOLECULE_ENV != "production"`.
Three new regression tests in `wsauth_middleware_test.go`:
- `TestAdminAuth_DevModeEscapeHatch_FailsOpenWithHasLiveTokens` — the
happy path (dev mode, no admin token, tokens exist → 200)
- `TestAdminAuth_DevModeEscapeHatch_IgnoredWhenAdminTokenSet` — explicit
`ADMIN_TOKEN` wins; dev mode does not silently re-open the gate
- `TestAdminAuth_DevModeEscapeHatch_IgnoredInProduction` — the
SaaS-safety guarantee (production + no admin token + tokens exist → 401)
`.env.example` flipped to set `MOLECULE_ENV=development` by default so
new users get the dev-mode hatch automatically via `cp .env.example .env`.
SaaS provisioning overrides to `production`, consistent with the existing
convention used by the secrets-encryption strict-init path.
### 2. SaaS cookie/privacy banner rendered on localhost
`CookieConsent` mounted unconditionally in the root layout, so
`npm run dev` on localhost showed a "Cookies & your privacy" banner
pointing at `moleculesai.app/legal/privacy`. That banner is a
GDPR/ePrivacy compliance UI that only applies to the hosted SaaS
offering; self-hosted / local-dev / Vercel-preview hosts must not
see it.
**Fix** (`canvas/src/components/CookieConsent.tsx`): gate render on
`isSaaSTenant()`. Matches the convention used by `AuthGate` and the
workspace tier picker elsewhere in the codebase.
Tests (`canvas/src/components/__tests__/CookieConsent.test.tsx`):
existing tests now stub `window.location.hostname` to a SaaS
subdomain before rendering (required since `isSaaSTenant()` on jsdom's
default "localhost" would suppress the banner). Added two new tests
for the local-dev hide path:
- `does NOT render on local dev (non-SaaS hostname)`
- `does NOT render on a LAN hostname (192.168.*, *.local)`
### Verification
On a fresh-nuked DB with the updated branch:
1. `bash infra/scripts/setup.sh` — clean
2. `go run ./cmd/server` — "Applied 41 migrations", :8080 healthy,
dev-mode hatch armed (`MOLECULE_ENV=development`)
3. `npm run dev` in canvas — :3000 renders, no cookie banner
4. `bash tests/e2e/test_api.sh` — **61 passed, 0 failed**
(test suite creates tokens; GET /workspaces stays 200 under the hatch)
5. Browser at http://localhost:3000 AFTER the e2e run:
- Canvas renders the workspace list (no 401 placeholder)
- No cookie banner
6. `npx vitest run` — **902 tests passed** (900 prior + 2 new hide tests)
7. `go test -race ./internal/middleware/` — all passing (3 new
dev-mode tests + existing Issue-180 / Issue-120 / Issue-684 suite),
coverage 81.8%
### SaaS parity audit
Same principle as the rest of this branch: local must work without
weakening SaaS.
- Dev-mode hatch: conditional on `MOLECULE_ENV=development`.
Production tenants always run `MOLECULE_ENV=production` (already
enforced by the secrets-encryption `InitStrict` path in
`internal/crypto/aes.go`). Branch is unreachable there.
- Cookie banner: gated on `isSaaSTenant()` which checks
`NEXT_PUBLIC_SAAS_HOST_SUFFIX` (default `.moleculesai.app`). SaaS
hosts still get the banner; every other host doesn't.
No change to SaaS behaviour. #1822 backend-parity tracker untouched.
