### Detailed Issue Description

Project: primetable (monorepo)

Service: @primetable/scraper

Repository: maxroebuck1/primetable

Region: europe-west4

Problem Summary

TypeScript build commands execute successfully during the build phase, but the compiled dist/ directory is not present in the deployed container, causing immediate crashes on startup.

Evidence of Successful Builds

Deployment ID: 8db0e12e-b9fd-48e0-8542-40dd8555cf28

Build logs show successful compilation:

```

2025-11-24T22:34:40 > @primetable/shared@1.0.0 build

2025-11-24T22:34:40 > tsc

2025-11-24T22:34:41 > @primetable/scraper@1.0.0 build

2025-11-24T22:34:41 > tsc -p tsconfig.json

Build completed successfully without errors.

Evidence of Missing Artifacts

Same deployment runtime logs:

```

2025-11-24T23:10:34 Starting Container

2025-11-24T23:10:34 Error: Cannot find module '/app/packages/scraper/dist/scheduler.js'

at Module._resolveFilename (node:internal/modules/cjs/loader:1420:15)

code: 'MODULE_NOT_FOUND'

```

The dist/scheduler.js file created during build is not present in the deployed container.

Configuration Details

railway.toml:

```toml

[build]

builder = "NIXPACKS"

buildCommand = "pnpm install --frozen-lockfile && pnpm --filter @primetable/shared build && pnpm --filter @primetable/scraper build && cd packages/scraper && npx playwright install firefox && npx playwright install-deps firefox"

[deploy]

startCommand = "cd packages/scraper && node dist/scheduler.js"

restartPolicyType = "ON_FAILURE"

```

Project Structure:

```

/packages/scraper/

├── src/

├── dist/ ← Created by tsc during build, missing in container

├── tsconfig.json

├── package.json

└── scheduler.ts (entry point)

```

What We've Tried

1. Dockerfile approach - same issue

2. Explicit buildCommand in railway.toml - ignored

3. .nixpacks.toml configuration - same issue

4. Recreated service fresh (no cache) - same issue

5. 40+ deployment attempts with various configs

Expected Behavior

The dist/ directory created by tsc during the build phase should be preserved and available in the deployed container at /app/packages/scraper/dist/.

Actual Behavior

Build completes successfully showing TypeScript compilation, but the compiled JavaScript files in dist/ are not included in the final deployed container image.

Question

How can we ensure TypeScript build artifacts from pnpm --filter @primetable/scraper build are preserved in the deployed Nixpacks container for a monorepo GitHub deployment?
