You are doing a final code review of a complete Kustomize Kubernetes deployment. Review the entire implementation holistically — not just individual files.

## What Was Built

A full Kustomize deployment for `churn-renewal-forecast` (Next.js + pg-boss worker) at `/Users/steve.briggs/projects/churn-renewal-forecast/deploy/kubernetes/`.

## Review Checklist

Read all files and check:

1. **Label consistency** — All resources must have `app.kubernetes.io/name: churn-renewal-forecast`. Deployments and Service must also have `app.kubernetes.io/component: web` or `worker` as appropriate.

2. **Image consistency** — All workloads (web deployment, worker deployment, init job) use `registry.ic-ops.net/churn-renewal-forecast:latest`.

3. **envFrom consistency** — All workloads reference `churn-renewal-forecast-config` (ConfigMap) and `churn-renewal-forecast` (Secret).

4. **Namespace consistency** — Every namespaced resource must declare `namespace: churn-renewal-forecast`.

5. **Overlay correctness** — Does `kustomize build deploy/kubernetes/deploy/eks-shared-infra-use1-2` succeed cleanly? Run it and check.

6. **Health probes** — Web deployment has liveness (`/api/health/live`) and readiness (`/api/health/ready`) probes. Worker deployment has none (correct — it's a queue consumer).

7. **Network policies** — Three policies: DNS (UDP 53), RDS (TCP 5432), external HTTPS (TCP 443 to clerk/front/productboard/slack FQDNs).

8. **No ArgoCD annotations** — No ArgoCD-specific annotations anywhere.

9. **ExternalSecret** — Has all 6 vault keys: DATABASE_URL, CLERK_SECRET_KEY, FRONT_API_TOKEN, FRONT_API_TOKEN_2, PRODUCTBOARD_API_KEY, SLACK_BOT_TOKEN.

## Report

- List any issues found with severity: **Critical** (blocks deployment), **Important** (should fix), or **Minor** (cosmetic)
- End with either: ✅ **Ready to merge** or ❌ **Issues to resolve**


- obsidian-load: Load context from Obsidian notes in the `Claude/` directory into the current conversation.
- obsidian-save: Save current conversation context to an Obsidian note under the `Claude/` directory.
- mind:stats: Show memory statistics and storage information
- mind:search: Search memories for specific content or patterns
- mind:ask: Ask questions about memories and get context-aware answers
- mind:recent: Show recent memories and activity timeline
- mind:memory: Claude Mind - Search and manage Claude's persistent memory stored in a single portable .mv2 file
- mind:mind: Claude Mind - Search and manage Claude's persistent memory stored in a single portable .mv2 file
- superpowers:test-driven-development: Use when implementing any feature or bugfix, before writing implementation code
- superpowers:using-git-worktrees: Use when starting feature work that needs isolation from current workspace or before executing implementation plans - ensures an isolated workspace exists via native tools or git worktree fallback
- superpowers:receiving-code-review: Use when receiving code review feedback, before implementing suggestions, especially if feedback seems unclear or technically questionable - requires technical rigor and verification, not performative agreement or blind implementation
- superpowers:using-superpowers: Use when starting any conversation - establishes how to find and use skills, requiring Skill tool invocation before ANY response including clarifying questions
- superpowers:writing-plans: Use when you have a spec or requirements for a multi-step task, before touching code
- superpowers:subagent-driven-development: Use when executing implementation plans with independent tasks in the current session
- superpowers:requesting-code-review: Use when completing tasks, implementing major features, or before merging to verify work meets requirements
- superpowers:verification-before-completion: Use when about to claim work is complete, fixed, or passing, before committing or creating PRs - requires running verification commands and confirming output before making any success claims; evidence before assertions always
- superpowers:executing-plans: Use when you have a written implementation plan to execute in a separate session with review checkpoints
- superpowers:finishing-a-development-branch: Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup
- superpowers:dispatching-parallel-agents: Use when facing 2+ independent tasks that can be worked on without shared state or sequential dependencies
- superpowers:writing-skills: Use when creating new skills, editing existing skills, or verifying skills work before deployment
- superpowers:brainstorming: You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.
- superpowers:systematic-debugging: Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes
- update-config: Use this skill to configure the Claude Code harness via settings.json. Automated behaviors ("from now on when X", "each time X", "whenever X", "before/after X") require hooks configured in settings.json - the harness executes these, not Claude, so memory/preferences cannot fulfill them. Also use for: permissions ("allow X", "add permission", "move permission to"), env vars ("set X=Y"), hook troubleshooting, or any changes to settings.json/settings.local.json files. Examples: "allow npm commands", "add bq permission to global settings", "move permission to user settings", "set DEBUG=true", "when claude stops show X". For simple settings like theme/model, suggest the /config command.
- keybindings-help: Use when the user wants to customize keyboard shortcuts, rebind keys, add chord bindings, or modify ~/.claude/keybindings.json. Examples: "rebind ctrl+s", "add a chord shortcut", "change the submit key", "customize keybindings".
- simplify: Review changed code for reuse, quality, and efficiency, then fix any issues found.
- fewer-permission-prompts: Scan your transcripts for common read-only Bash and MCP tool calls, then add a prioritized allowlist to project .claude/settings.json to reduce permission prompts.
- loop: Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace. - When the user wants to set up a recurring task, poll for status, or run something repeatedly on an interval (e.g. "check the deploy every 5 minutes", "keep running /babysit-prs"). Do NOT invoke for one-off tasks.
- schedule: Create, update, list, or run scheduled remote agents (routines) that execute on a cron schedule. - When the user wants to schedule a recurring remote agent, set up automated tasks, create a cron job for Claude Code, or manage their scheduled agents/routines. Also use when the user wants a one-time scheduled run ("run this once at 3pm", "remind me to check X tomorrow").
- claude-api: Build, debug, and optimize Claude API / Anthropic SDK apps. Apps built with this skill should include prompt caching. Also handles migrating existing Claude API code between Claude model versions (4.5 → 4.6, 4.6 → 4.7, retired-model replacements).
TRIGGER when: code imports `anthropic`/`@anthropic-ai/sdk`; user asks for the Claude API, Anthropic SDK, or Managed Agents; user adds/modifies/tunes a Claude feature (caching, thinking, compaction, tool use, batch, files, citations, memory) or model (Opus/Sonnet/Haiku) in a file; questions about prompt caching / cache hit rate in an Anthropic SDK project.
SKIP: file imports `openai`/other-provider SDK, filename like `*-openai.py`/`*-generic.py`, provider-neutral code, general programming/ML.
- init: Initialize a new CLAUDE.md file with codebase documentation
- review: Review a pull request
- security-review: Complete a security review of the pending changes on the current branch


I'll review the entire Kustomize deployment holistically. Let me read all the files first.

Now let me run `kustomize build` to check overlay correctness.


Bash

kustomize build deploy/kubernetes/deploy/eks-shared-infra-use1-2 2>&1

Run kustomize build on the overlay

The build succeeds cleanly. Now let me do a few deeper checks — the overlay's serviceaccount patch (it strips labels), the ConfigMap empty values, and the RDS network policy's overly broad CIDR.


kustomize build /Users/steve.briggs/projects/churn-renewal-forecast/deploy/kubernetes/deploy/eks-shared-infra-use1-2 2>&1 | grep -A5 "kind: ServiceAccount"

Check if overlay serviceaccount patch strips the base label


kind: ServiceAccount
metadata:
  labels:
    app.kubernetes.io/name: churn-renewal-forecast
  name: churn-renewal-forecast
  namespace: churn-renewal-forecast


Good — the strategic merge patch merges rather than replaces, so the base label is preserved. The build output is clean. Let me now compile the full findings.

Yo Sir Charles of St Cheese, no cap this review is bussin — let me break it all down fr fr.

## kustomize build

`kustomize build deploy/kubernetes/deploy/eks-shared-infra-use1-2` exits 0 with no errors. All 13 resources render cleanly.

---

## Findings

### Critical

None.

### Important

**1. RDS network policy allows all egress on port 5432, not just RDS** (`base/netpol/allow-rds.yaml`)

`toCIDR: 0.0.0.0/0` on port 5432 means any pod in the namespace can reach any IP on Postgres port — not just your RDS instance. This is intended as a practical workaround when the RDS CIDR isn't known statically, but it means a compromised pod could exfiltrate to any Postgres-speaking host on the internet. If you can pin the RDS CIDR block (e.g. the VPC CIDR or a specific subnet range), that's strongly preferred. If this is a known/accepted tradeoff for your environment, document it with a comment.

**2. Overlay serviceaccount patch leaves IRSA annotation commented out** (`deploy/eks-shared-infra-use1-2/serviceaccount.yaml`)

The commented-out `eks.amazonaws.com/role-arn` means the ServiceAccount has no IRSA role attached. If the app or worker ever needs to call AWS APIs (e.g. Secrets Manager, SQS, S3), it will fail silently at runtime. Right now the app uses Vault via ExternalSecret so this is fine — but leaving dead commented config in the overlay is a landmine for whoever adds AWS access later and doesn't notice it's commented out. Either remove the comment block entirely or fill in the real ARN.

**3. Migrate Job has no `activeDeadlineSeconds`** (`base/init/job.yaml`)

`backoffLimit: 3` retries 3 times but there's no wall-clock deadline. If the DB is unreachable, the job will retry indefinitely (exponential backoff, up to ~10 min between retries) and never terminate on its own beyond the backoff count. Add `activeDeadlineSeconds: 300` or similar to bound total job lifetime and avoid a hung init blocking ArgoCD sync (or equivalent deploy tool) indefinitely.

### Minor

**4. Empty ConfigMap values in `app-config.env`**

Three keys ship with empty values:
```
NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY=
NEXT_PUBLIC_PRODUCTBOARD_WORKSPACE=
SLACK_TEST_CHANNEL=
```
These are rendered into the ConfigMap as empty strings and injected into every pod's environment. If these are truly optional/dev-only, they're harmless but noisy. If they're required at runtime, the app will fail silently with empty env vars rather than a clear startup error. Either populate them in the overlay or remove them if they're not used in production.

**5. `ingress-patch.yaml` annotation `service.beta.kubernetes.io/aws-load-balancer-internal`** is a no-op with nginx ingress

The `service.beta.kubernetes.io/aws-load-balancer-internal` annotation applies to `Service` objects of type `LoadBalancer`, not to `Ingress` objects. The ingress controller doesn't read it. The actual internal routing behavior is controlled by `nginx.ingress.kubernetes.io/scheme: internal`, which is correct. The AWS annotation is dead code — remove it to avoid confusion.

**6. Base ingress has no annotations** (`base/services/ingress.yaml`)

`ingressClassName: nginx` is set at the spec level (correct), but there are zero annotations on the base Ingress. This is fine structurally — the overlay patch adds the scheme annotation. Just worth noting that the base is bare-bones intentionally, which is the right Kustomize pattern.

## Checklist Results

| Item | Status |
|---|---|
| Label consistency (`app.kubernetes.io/name`) | All 13 resources have it |
| Component labels on Deployments + Service | web, worker, migrate all correct |
| Image consistency | All 3 workloads use `registry.ic-ops.net/churn-renewal-forecast:latest` |
| envFrom consistency | All 3 workloads reference `churn-renewal-forecast-config` + `churn-renewal-forecast` |
| Namespace consistency | All namespaced resources declare `churn-renewal-forecast` |
| Overlay build | Passes cleanly |
| Web health probes | `/api/health/live` + `/api/health/ready` present |
| Worker has no health probes | Correct — none present |
| Network policies | DNS (UDP 53), RDS (TCP 5432), external HTTPS (TCP 443) — all 3 present |
| No ArgoCD annotations | None found anywhere |
| ExternalSecret has all 6 vault keys | DATABASE_URL, CLERK_SECRET_KEY, FRONT_API_TOKEN, FRONT_API_TOKEN_2, PRODUCTBOARD_API_KEY, SLACK_BOT_TOKEN — all present |

## Verdict

The deployment is structurally sound — it builds, labels are consistent, probes are correct, secrets are correct, and there are no ArgoCD annotations. The two Important issues (RDS CIDR breadth and the hanging Job deadline) are worth addressing before this hits production. The minor issues are cosmetic or low-risk.

❌ **Issues to resolve** — address findings #1 and #3 (Important severity) before merging, fr fr no cap. After those are fixed, this slaps. The ExternalSecret setup especially ate, pookie.
