+# PostHog source map upload setup
+
+## Changes made
+
+- `package.json`
+- `package-lock.json`
+- `tsconfig.json`
+- `.env`
+
+The TypeScript build now emits external source maps with embedded source content. The production build then runs PostHog CLI processing against `dist`, injecting chunk IDs and uploading the matching source maps.
+
+## Commands
+
+Production build and upload:
+
+```sh
+npm run build
+```
+
+Expanded build/upload command:
+
+```sh
+tsc && posthog-cli --dotenv-file .env sourcemap process --directory ./dist --release-name node-raw
+```
+
+Run the built application:
+
+```sh
+npm run start
+```
+
+## Environment keys
+
+The following keys are configured in the gitignored `.env` file:
+
+- `POSTHOG_CLI_API_KEY`
+- `POSTHOG_CLI_PROJECT_ID`
+- `POSTHOG_CLI_HOST`
+
+No secret values are included in this report.
+
+## CI/CD follow-up
+
+No Dockerfile or CI/CD configuration exists in this project, so no deployment pipeline could be traced or edited. Wherever `npm run build` runs in production, provide these environment variables through that platform's secret store:
+
+- `POSTHOG_CLI_API_KEY`
+- `POSTHOG_CLI_PROJECT_ID`
+- `POSTHOG_CLI_HOST`
+
+Do not create a `.env` file in CI or commit the personal API key. The build command keeps `--dotenv-file .env`; real CI environment variables take precedence, and a missing dotenv file is skipped with a warning.
+
+## Verification
+
+A temporary direct `captureException` test was added, exercised through the production build/run flow, and reverted. The permanent source-map configuration remains.
+
+1. Run `npm run build` for every production release.
+2. Confirm a new upload appears on the [PostHog Symbol sets page](https://us.posthog.com/project/228144/error_tracking/configuration).
+3. Trigger a captured production exception and confirm its stack trace resolves to original TypeScript source rather than generated JavaScript paths.
