feat(staging): scope staging sign-in to the team - #3097
Staging register + login were ungated. REGISTRATION_INVITE_ONLY was on, but AUTH_ALLOWED_DOMAINS/AUTH_ALLOWED_EMAILS were unset, so instanceAccessPolicy.isInstanceAccessRestricted() returned false and any invite code let any email register and sign in. This scopes staging sign-in to the team.
How (staging only — prod stays public)
values-staging.yaml: AUTH_ALLOWED_DOMAINS = "seed.staging.commonly.me,ops.commonly.invalid" — the first covers the seed accounts, the second covers both CI smoke accounts (they are @ops.commonly.invalid). Plus a flag to surface AUTH_ALLOWED_EMAILS.
backend-deployment.yaml + ops-runner-deployment.yaml: AUTH_ALLOWED_DOMAINS (from values) and AUTH_ALLOWED_EMAILS (from the api-keys secret), each behind its own {{- if }} guard. ops-runner mirrors backend per opsRunnerEnvMirror.test.js.
api-keys.yaml ExternalSecret: a gated auth-allowed-emails entry, following the existing Slack-block rule that the remote key must exist in Secret Manager before the flag flips.
Individual team-member emails are PII and live only in the GCP Secret Manager secret — never in this repo.
Safety: prod is untouched
values-dev sets none of these flags. Verified with helm template on both value sets:
staging render: all additions present; remoteRef resolves to the staging-prefixed key.
dev/prod render: zero AUTH_ALLOWED_* env lines and no new ExternalSecret key → prod stays public and its api-keys ESO sync is unchanged.
Behavioral consequence (surfaced by the review)
Restricting staging changes sign-in behavior — the intended tightening:
Email/password self-register returns 503 (INSTANCE_VERIFICATION_UNAVAILABLE) because staging has no SMTP. New team members sign in with OAuth (Google/GitHub, verified + allowlisted) or a pre-verified seeded account, not email/password signup.
Login requires a verified account when restricted. The Tier-1 staging-smoke is login-only and both its @ops.commonly.invalid accounts are verified + domain-allowlisted (confirmed via a live staging login), so it stays green.
Latent: the register-based stranger-journey smoke is not in the staging release today; if it is ever added it would 503 under restriction and need SMTP or a pre-verified account. Tracked as a follow-up.
Verify after deploy
A non-allowlisted @example.com is refused at both register and login.
A seed account (@seed.staging.commonly.me) still signs in.
staging-smoke green (login-only, both accounts verified + allowlisted).
Seed accounts are created via direct Mongo upsert, not the register HTTP path.

Walkthrough
The Helm chart configures staging sign-in allowlists, optionally maps allowed emails from an ExternalSecret, and exposes the domain and email settings to the backend and ops-runner as environment variables.
Changes: Staging sign-in configuration
Layer / File(s)
Summary
Configure staging allowlists and email secret k8s/helm/commonly/values-staging.yaml, k8s/helm/commonly/templates/secrets/api-keys.yaml
Staging values allow the seed.staging.commonly.me and ops.commonly.invalid domains and enable secret-sourced emails. When enabled, the ExternalSecret maps the prefixed remote email key.
Expose allowlists to workloads k8s/helm/commonly/templates/core/backend-deployment.yaml, k8s/helm/commonly/templates/ops/ops-runner-deployment.yaml
When configured, both Deployments set AUTH_ALLOWED_DOMAINS from values and AUTH_ALLOWED_EMAILS from the api-keys secret.
Team-Commonly/commonly#2578: Implements the sign-in policy that uses AUTH_ALLOWED_EMAILS and AUTH_ALLOWED_DOMAINS.
Team-Commonly/commonly#3081: Seeds staging accounts with the seed.staging.commonly.me domain configured in this change.
Team-Commonly/commonly#2475: Defines the ops-runner environment-mirror contract and tests matching backend and ops-runner environment entries.
Merge Risk: Moderate · up to 9c5b7
Confirm the staging email secret has a usable version before rollout and add render assertions for staging and dev. Otherwise, staging sign-in may become unavailable if the secret is missing, and the intended configuration could regress unnoticed.

Add render assertions for the staging-only allowlist wiring.
The new AUTH_ALLOWED_DOMAINS and AUTH_ALLOWED_EMAILS entries in k8s/helm/commonly/templates/core/backend-deployment.yaml control both registration and login. No CI workflow or Kubernetes file references these variable names. A revert of this wiring, or of the staging values, would not fail any repository check.
Extend the existing helm template render checks to assert the following:
Staging renders AUTH_ALLOWED_DOMAINS with the configured domain list.
Staging renders AUTH_ALLOWED_EMAILS as a secretKeyRef to api-keys / auth-allowed-emails.
Staging renders the commonly-staging-auth-allowed-emails ExternalSecret entry.
Production values render neither AUTH_ALLOWED_DOMAINS nor AUTH_ALLOWED_EMAILS.
Each assertion should fail when this wiring is removed.

GATE: PASS at 5fcfc6a — Sable, helm-only change; all four of Lily's checks hold, two non-blocking notes below
Checked at 5fcfc6a (head unchanged right before filing), with helm template on Helm 3 and a detached worktree.
Staging-only: helm template with values-dev renders byte-identical to main (0 differing lines), so zero AUTH_ALLOWED lines and no new api-keys key. Prod stays public.
Staging render: the backend gets AUTH_ALLOWED_DOMAINS="seed.staging.commonly.me,ops.commonly.invalid" and AUTH_ALLOWED_EMAILS from secretKeyRef api-keys/auth-allowed-emails. The ExternalSecret adds auth-allowed-emails with remoteRef.key: commonly-staging-auth-allowed-emails. That is the whole staging diff against main: 17 lines, nothing else moved.
ops-runner mirror: staging has opsRunner.enabled off, so it renders none today. With --set opsRunner.enabled=true the render shows 4 AUTH_ALLOWED lines (2 backend, 2 ops-runner). opsRunnerEnvMirror.test.js passes 2/2, and when I delete the ops-runner secret-ref block it fails the tuple check (mutant killed, restored).
No PII in the diff. Only the two domains are committed, and those are seed and reserved-TLD domains. Team emails sit behind the secret ref.
Backend semantics, read at the head (instanceAccessPolicy.ts, authController.ts): either variable set means restricted. Register refuses a non-allowlisted email (403). Login also requires verified while restricted. Register returns 503 when restricted without SMTP, so a stranger cannot self-register onto the ops.commonly.invalid domain: staging has no SMTP, so register is refused outright.
Non-blocking:
Latent smoke break. files/stranger-journey.py signs up through POST /api/auth/register. On staging that will now return 503 INSTANCE_VERIFICATION_UNAVAILABLE. It is green today only because the stranger-journey CronJob isn't in the staging release (it renders 0 times on values-staging), and deploy-staging.yml falls back to a reachability probe on NotFound. The PR's "staging-smoke stays green" holds for the Tier-1 Playwright smoke, which only logs in. It will not hold for the stranger smoke once that CronJob lands on staging. Whoever enables it needs a verified smoke account, or an allowlisted path that skips register.
Deploy precondition I can't see from here. The staging deploy runs on push to main. A backend pod whose secretKeyRef key is missing from api-keys fails with CreateContainerConfigError, and a missing remoteRef also stops ESO syncing the whole secret. The PR body says commonly-staging-auth-allowed-emails is already created with v1 enabled. I have no Secret Manager access and did not check, so confirm that before the merge lands. Also check that the two Playwright smoke accounts (SMOKE_EMAIL, SMOKE_FRESH_EMAIL) are on ops.commonly.invalid, since those repo secrets are not readable either.
Staging register + login were ungated: REGISTRATION_INVITE_ONLY was on but
AUTH_ALLOWED_DOMAINS/EMAILS were unset, so
instanceAccessPolicy.isInstanceAccessRestricted() returned false and any
invite code let any email register and sign in.
Scope sign-in to the team on staging only:
- values-staging: AUTH_ALLOWED_DOMAINS = seed.staging.commonly.me (seed
accounts) + ops.commonly.invalid (both CI smoke accounts, so staging-smoke
stays green), plus a flag to surface AUTH_ALLOWED_EMAILS from the secret.
- backend-deployment + ops-runner: both env vars behind their own {{- if }}
guards (ops-runner mirrors backend per opsRunnerEnvMirror.test.js).
- api-keys ExternalSecret: a gated auth-allowed-emails entry (remoteRef
commonly-staging-auth-allowed-emails), same "remote key must exist first"
rule as the Slack block.
Team-member emails live only in the GCP Secret Manager secret, never in the
repo.
Prod/values-dev sets none of these: both templates render zero AUTH_ALLOWED
lines and no new ExternalSecret key, so prod stays public and its api-keys
sync is unchanged (verified via helm template on both value sets).

Writer's Sonnet-class adversarial review (auth change), head 9c5b7da. Verified:
Prod untouched — helm template on values-dev renders ZERO AUTH_ALLOWED_* env lines and no new api-keys ExternalSecret key (backend, ops-runner, ES); the staging render has all three and the remoteRef resolves to the staging-prefixed key. Prod stays public.
Backend semantics (instanceAccessPolicy + authController) — a non-empty AUTH_ALLOWED_* flips isInstanceAccessRestricted() true; the gate applies to register, login and OAuth; domain match is trim/lowercase-safe; no fail-open (an empty AUTH_ALLOWED_EMAILS is still restricted by the domain list).
Active Tier-1 staging-smoke stays green — it is login-only for both the seeded and FRESH accounts, and both @ops.commonly.invalid accounts are confirmed verified: true + domain-allowlisted, so login returns 200 under restriction (confirmed via a live staging login read).
ops-runner mirror — backend and ops-runner declare identical env tuples (opsRunnerEnvMirror.test.js); the diff carries no email/secret values (team emails only in GCP SM).
Documented consequence (not a code defect): under restriction + no staging SMTP, email/password self-register returns 503 — the intended tightening; sign-in is OAuth or pre-verified/seeded accounts. Latent: a register-based staging smoke would 503 (stranger-journey is not in the staging release today) — follow-up filed.

Add mutation-sensitive Helm render assertions.
The policy test checks allowlist matching, and the ops-runner test checks raw template parity. The ops-runner test does not render Helm. CI also only parses the dev and staging renders.
Assert that staging renders AUTH_ALLOWED_DOMAINS, AUTH_ALLOWED_EMAILS, and commonly-staging-auth-allowed-emails, while the dev render contains none of them. Each assertion must fail when its corresponding wiring is reverted.
The dev assertion is material for the current dev-public contract. The repository has no values-prod.yaml, so it does not provide a separate production values/render path to test.
