fix(staging): enable LiteLLM so native-runtime agents (Scout) can answer - #3077
Enable LiteLLM in the commonly-staging namespace so native-runtime agents (Scout's onboarding replies) can run turns.
Why — the 2026-10-31 staging-walk incident
Sam, testing a fresh staging signup: "is scout not working? I saw it not responding in staging." Scout posted its welcome at 11:25Z, then gave no reply to either onboarding button click (11:26:51Z, 11:27:11Z).
Traced read-only (ops-runner / throwaway pods, no exec into serving backend):
Both AgentRuns failed: status=failed, model=undefined, no cost, "native runtime failed: turn failed".
Root cause: values-staging.yaml had no litellm: stanza, so it inherited the base default litellm.enabled:false — there is no litellm in commonly-staging. But the staging backend still points native-runtime turns at http://litellm:4000, which doesn't resolve in that namespace, so every reply turn fails. The welcome posted because it's a scripted post, not an LLM turn.
Prod is unaffected (litellm 1/1 in commonly-dev); Scout's last 12 onboarding runs on commonly.me all succeeded. Only values-staging.yaml + a new test change here, so prod rendering is unchanged by construction.
How — kept small
All of litellm's secrets already exist in the staging api-keys ring (deepseek-api-key, cloudflare-account-id/-workers-ai-token, gemini/openrouter/openai-api-key, litellm-master-key), and DATABASE_URL reuses staging's own Aiven Postgres via ?schema=litellm. So this is a config enable — no new secret, no new database:
master key only (serviceKeys.fromSecret:false) — no budgeted virtual keys to mint in Secret Manager. Cost ceiling is the shared config's deepseek-v4-flash group max_budget ($60/1mo), metered in this instance's router cache.
Codex off (codexAuthRotator.enabled:false) — staging has no Codex traffic; Scout runs on deepseek-v4-flash (the backend's LITELLM_CHAT_MODEL, cheapest route it works on). The codex-cli/codex-auth-seed containers still render (ungated in the template) but idle harmlessly — the seed writes an empty auth.json and exits 0.
no chatgpt-auth PVC (emptyDir); dev-pool scheduling so a spot reclaim doesn't drop Scout mid-walk.
Verification
helm template with values-staging: litellm Deployment + Service + ConfigMap render; codex-auth-rotator is gated out; pool: dev nodeSelector/toleration present; DEEPSEEK_API_KEY wired; DATABASE_URL = ...commonly_staging?sslmode=require&schema=litellm.
New guard test backend/__tests__/unit/helm/litellmStagingEnabled.test.js asserts staging (and prod) keep litellm enabled and the small config holds — so staging can't again point its backend at a litellm that isn't deployed. 6/6 assertions pass.
Ships to staging on merge (staging auto-deploys); I'll confirm a live Scout reply in the walk pod after rollout.
…wer (D20)
values-staging had no `litellm:` stanza, so it inherited the base default
`enabled:false` — no litellm in commonly-staging. The staging backend still
points native-runtime turns at http://litellm:4000, so every Scout onboarding
REPLY turn failed ("native runtime failed: turn failed", model undefined, no
cost) while the scripted welcome still posted. 2026-10-31 staging-walk incident
(Sam: "is scout not working? I saw it not responding in staging").
Enable it, kept small (spend approved for Sam's checks + dev:live screenshots):
- master key only (serviceKeys.fromSecret:false) — no budgeted virtual keys to mint
- Codex rotator off (staging has no Codex traffic; Scout runs on deepseek-v4-flash,
the cheapest route it works on). codex-cli/seed still render but idle harmlessly
- no chatgpt-auth PVC (emptyDir); dev-pool so Sam-check turns aren't reclaimed mid-walk
No new secret or DB: every key already exists in the staging api-keys ring, and
DATABASE_URL reuses staging's own Aiven via ?schema=litellm. Guard test asserts
staging (and prod) keep litellm enabled and the small config holds.

Walkthrough
Staging Helm values now enable LiteLLM and set authentication and scheduling options. A new unit test checks LiteLLM enablement in staging and dev and verifies selected staging settings.

Summary
Staging configuration and validation k8s/helm/commonly/values-staging.yaml, backend/__tests__/unit/helm/litellmStagingEnabled.test.js
Staging enables LiteLLM, disables service-key generation from secrets, Codex auth rotation, and ChatGPT auth persistence. It selects the default node pool. The test checks enablement in staging and dev, plus the staging authentication and scheduling settings.
Team-Commonly/commonly#1050: The PR disables the Codex auth rotator for staging LiteLLM; the issue also tracks removing that rotator, though its sidecar cleanup remains unaddressed.
Team-Commonly/commonly#541: The PR enables staging LiteLLM for native-runtime agents with the master key configured, which overlaps the issue’s described native-application access objective.
Possibly related PRs
Team-Commonly/commonly#2748: That PR introduced the service-key secret setting used by LiteLLM; this PR configures the setting for staging.

The test does not assert staging.litellm.chatgptAuth.persistence.enabled or the rendered storage resources. If this value changes to true, the current assertions still pass while Helm renders a PVC instead of emptyDir. Add coverage for the effective false value, the Deployment's emptyDir volume, and the absence of the LiteLLM auth PVC.

…odexBypassLitellm (review)
Writer's subagent review (D218) caught a scheduling risk and a dead-config line.
- nodeSelector pool:dev -> pool:default (drop the toleration). The reviewer's STATED
reason ("no pool=dev node in staging") is a false positive — staging and prod are two
namespaces in ONE cluster, node pools are cluster-scoped, and prod litellm runs on the
dev-pool node right now with this exact selector. But the reviewer's TARGET is right for
a better reason: dev-pool is a SINGLE node already running prod litellm + clawdbot +
cloud-codex, so pinning the reckless staging lane there lets it pressure the one node
serving PROD agent runtimes. The untainted default-pool is two nodes, not spot (Scout is
never reclaimed mid-walk), isolated from prod, and schedulable: the pod requests only
120m CPU / 576Mi and a default-pool node had ~377m CPU free when measured. Empty
tolerations + pool=default keep it off both tainted pools (dev, spot). Prod (values-dev)
is unchanged — still dev-pool + toleration.
- Remove `codexBypassLitellm: false`: dead config restating values.yaml's base default; the
backend reads CODEX_BYPASS_LITELLM from backend.env, not this chart field.
codex-cli sidecar + codex-auth-seed render ungated in the shared template but do not gate
litellm readiness or block Scout; gating them on codex-enabled is a tracked follow-up.
Guard test updated to assert default-pool + empty tolerations. helm template verified:
staging litellm -> nodeSelector pool:default, no tolerations; prod render unchanged.

Writer's subagent review (D218) ran and is addressed at head 20c5969b68. Recording the findings and resolutions:
litellm nodeSelector: pool: dev unschedulable in staging — stated reason is a false positive, but the fix is right. Staging and prod are two namespaces in one cluster (node pools are cluster-scoped), the pool=dev node exists, and prod litellm runs on it right now with this exact selector — so it would have scheduled. But dev-pool is a single node already running prod litellm + clawdbot + cloud-codex; pinning the reckless staging lane there lets it pressure the one node serving prod agent runtimes. Switched to the untainted default-pool (nodeSelector: pool: default, no tolerations): two nodes, not spot (so Scout isn't reclaimed mid-walk), isolated from prod, and schedulable — the pod requests only 120m CPU / 576Mi and a default-pool node had ~377m CPU free when measured. helm template confirms staging → pool: default / no tolerations; prod (values-dev) render unchanged.
Guard test cements the misconfig — resolved by (1); test now asserts pool: default + empty tolerations, with the rationale inline.
codex-cli sidecar + codex-auth-seed render ungated — true, and pre-existing in the shared template (affects prod too, where the rotator is on). It does not gate litellm readiness or block Scout (seed exits 0; sidecar has no readiness probe), so it's waste/boot-slowdown, not a blocker for this PR. Deferred to a tracked follow-up (gate both on codex-enabled in a separate template PR that keeps prod's render identical).
Dead codexBypassLitellm: false — removed; it restated values.yaml's base default and the backend reads CODEX_BYPASS_LITELLM from backend.env, not this field.
The staging values omit litellm.tolerations, so this assertion passes even if values.yaml later supplies a non-empty default. Helm would merge that default, and the template would render it into the staging Deployment. Assert the merged values or rendered Deployment instead.
This is a recommended test-coverage improvement, not a current scheduling defect.

…(CodeRabbit #3077)
Guard against a silent flip of litellm.chatgptAuth.persistence.enabled to true, which
would render a LiteLLM auth PVC in the reckless, resettable staging namespace. Asserted
at the values altitude (the test's level); the rendered emptyDir / PVC-absence is
exercised by the Chart Lint CI tier that templates the chart.

Addressed the emptyDir nitpick in b10cfcea: the guard test now asserts litellm.chatgptAuth.persistence.enabled stays false (catches a silent flip that would render a LiteLLM auth PVC in the resettable staging namespace). Left the rendered-volume / PVC-absence check to the Chart Lint CI tier, which templates the chart — the unit test guards at the values altitude.
The reason will be displayed to describe this comment to others. Learn more.
D218 review round complete at b10cfceac9.
Writer's subagent review (medium) found a load-bearing scheduling bug and it's fixed: nodeSelector: pool: dev would have pinned staging litellm to the shared cluster's single dev-pool node — the one already running prod litellm + clawdbot + cloud-codex — letting the reckless staging lane pressure prod's agent-runtime node. Switched to the untainted default-pool (empty tolerations + pool: default): verified schedulable (pod requests 120m CPU / 576Mi; a default-pool node had ~377m CPU free when measured), helm template confirms staging → pool: default with no tolerations, and prod (values-dev) render is byte-unchanged. Also removed dead codexBypassLitellm: false and strengthened the guard test (default-pool + emptyDir persistence assertions).
Fix mechanism verified: native-runtime master-key fallback works with serviceKeys.fromSecret:false; every litellm secret already exists in the staging api-keys ring; DATABASE_URL reuses staging's Aiven via ?schema=litellm. No new secret, no new DB.
CodeRabbit: one Trivial nitpick (persistence guard) — addressed in b10cfcea. CI: green at this head — 30 checks pass, 0 fails (Chart Lint Tier-1.5, backend/service shards, E2E, CodeQL, kind cluster all green).
One tracked follow-up (not a blocker): the codex-cli sidecar + codex-auth-seed init render ungated in the shared litellm template; they don't gate litellm readiness or block Scout. Gating them on codex-enabled is a separate template PR.
