You are reviewing whether an implementation matches its specification.

## What Was Requested

Task 5: Create the Dockerfile at the project root. The spec Dockerfile content is:

```dockerfile
# Stage 1: production-only dependencies
FROM oven/bun:1-node24-slim AS deps
WORKDIR /app

COPY package.json bun.lock .npmrc ./
COPY prisma ./prisma

RUN bun install --frozen-lockfile --production --ignore-scripts

# Stage 2: full install, prisma generate, next build
FROM oven/bun:1-node24-slim AS build
WORKDIR /app

COPY package.json bun.lock .npmrc ./
COPY prisma ./prisma

RUN bun install --frozen-lockfile

COPY . .

RUN bunx prisma generate
RUN bun run build

# Stage 3: minimal runtime image
FROM oven/bun:1-node24-slim AS runner
WORKDIR /app

ENV NODE_ENV=production
ENV PORT=3000
ENV HOSTNAME=0.0.0.0

RUN groupadd --system --gid 1001 nodejs \
    && useradd --system --uid 1001 --gid nodejs nextjs

COPY --from=build --chown=nextjs:nodejs /app/.next/standalone/app/ ./
COPY --from=build --chown=nextjs:nodejs /app/.next/static ./.next/static
COPY --from=build --chown=nextjs:nodejs /app/public ./public
COPY --from=build --chown=nextjs:nodejs /app/src/worker ./src/worker
COPY --from=build --chown=nextjs:nodejs /app/src/lib ./src/lib
COPY --from=build --chown=nextjs:nodejs /app/src/generated ./src/generated
COPY --from=build --chown=nextjs:nodejs /app/tsconfig.json ./tsconfig.json
COPY --from=build --chown=nextjs:nodejs /app/prisma ./prisma
COPY --from=deps --chown=nextjs:nodejs /app/node_modules ./node_modules

USER nextjs
EXPOSE 3000
CMD ["bun", "server.js"]
```

Only `Dockerfile` should be created. No other files should be modified.

## Known Legitimate Deviations

The implementer encountered real issues during the build that required adjustments. These are ACCEPTABLE deviations you should NOT flag:
1. **Base image tag `oven/bun:1-slim`** — `oven/bun:1-node24-slim` does not exist on Docker Hub. `oven/bun:1-slim` is the correct fallback. ✅
2. **Standalone copy path `COPY /app/.next/standalone/ ./`** — The actual Next.js standalone output in Docker with WORKDIR /app is flat (not nested under `app/`). The implementer verified this directly. ✅
3. **No `COPY public/`** — The project has no `public/` directory. Removing this line prevents a build error. ✅

## What to Flag

Look for issues NOT in the acceptable deviations list above. Specifically check:

1. **`ENV DATABASE_URL`**: The Dockerfile has `ARG DATABASE_URL=... + ENV DATABASE_URL=${DATABASE_URL}`. The `ENV` line bakes the placeholder value into the final image layer, making it visible via `docker history` and potentially confusing (though it gets overridden at runtime). The correct approach is to scope it only to the RUN command: `RUN DATABASE_URL=${DATABASE_URL} bun run build` — no `ENV` line needed. Is this present and is it a problem?

2. **`src/app/api/health/ready/route.ts` modified**: The implementer added `export const dynamic = "force-dynamic"` to this file. This was NOT in the task scope. Check if this file was committed as part of the Dockerfile commit. Run `git -C /Users/steve.briggs/projects/churn-renewal-forecast show --stat HEAD` to see what files were in the commit.

## Your Job

Read the actual Dockerfile at `/Users/steve.briggs/projects/churn-renewal-forecast/Dockerfile` and check git. Do NOT trust the implementer's report.

- 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

    feat: add 3-stage dockerfile ate that one bussin no cap

    - oven/bun:1-slim base (1-node24-slim tag not found on registry)
    - dummy DATABASE_URL build arg so next build doesn't cry
    - force-dynamic on /api/health/ready so it's never statically rendered
    - standalone path is flat at .next/standalone/ in Docker (no app/ nesting)
    - no public/ dir in this project so that COPY was dropped

Two issues found, Sir Charles of St Cheese. No cap, fr fr:

**❌ Issues Found**

---

**Issue 1: `ENV DATABASE_URL` bakes placeholder into the image layer**

`Dockerfile` lines 28–29:
```dockerfile
ARG DATABASE_URL=postgresql://placeholder:placeholder@localhost:5432/placeholder
ENV DATABASE_URL=${DATABASE_URL}
```

The `ENV` line converts the build arg into a permanent image layer environment variable. This means:
- The placeholder value is visible via `docker history` / `docker inspect` in the final `build` stage (even though it's a multi-stage build and the runner stage doesn't inherit it, the `build` stage image layer retains it)
- It's semantically misleading — baking a `DATABASE_URL` into the image is a bad security habit even with a placeholder

The correct approach per spec is to scope it only to the `RUN` command:
```dockerfile
ARG DATABASE_URL=postgresql://placeholder:placeholder@localhost:5432/placeholder
RUN DATABASE_URL=${DATABASE_URL} bun run build
```

No `ENV` line needed. The `ARG` alone is sufficient.

---

**Issue 2: `src/app/api/health/ready/route.ts` was modified**

The git commit `50a3a75` includes **two files changed**:
- `Dockerfile` ✅ (in scope)
- `src/app/api/health/ready/route.ts` ❌ (out of scope — Task 5 was Dockerfile only)

The commit message even calls it out: *"force-dynamic on /api/health/ready so it's never statically rendered"*. This is a behavioral change to a route file that was not part of the task specification. It should have been either raised as a separate task or flagged for explicit approval before being committed.

---

**Summary**

| Check | Result |
|---|---|
| Base image `oven/bun:1-slim` | ✅ Acceptable deviation |
| Standalone copy path `COPY .next/standalone/ ./` | ✅ Acceptable deviation |
| No `COPY public/` | ✅ Acceptable deviation |
| `ENV DATABASE_URL` baking placeholder into layer | ❌ Should be `RUN DATABASE_URL=... bun run build` |
| `src/app/api/health/ready/route.ts` modified | ❌ Out of scope — not part of Task 5 |
