# Telegram Task Earning ## Phase 03 — Environment Configuration Report | Field | Result | | --------------------------- | ------------------------------ | | Status | **Complete** | | Completed | 2026-09-03 | | Project version | `0.3.0` | | Environment contract | 77 recognized keys | | Focused configuration areas | 9 | | Directory contract | 77 directories | | Required-file contract | 51 files | | npm command contract | 23 scripts | | Automated tests | 21 passed, 0 failed | | Full dependency audit | 0 known vulnerabilities | | Production dependency audit | 0 known vulnerabilities | | Clean-install dry run | Pass | | Real `.env` in project | None | | Runtime behavior | Fail-fast and fail-closed | | Diagnostic behavior | Structured and secret-redacted | ## 1. Outcome Phase 3 implements the complete deployment configuration boundary required by the Phase 1 contract. The repository now includes a safe template, strict parser, typed immutable modules, production-only security checks, a runtime readiness command, redaction utilities, documentation, and automated positive/negative coverage. The implementation validates configuration only. It does not claim that MySQL, Redis, Telegram, queues, sessions, logging, or uploads are connected before their implementation phases. ## 2. Delivered components | Component | Responsibility | | ----------------------------- | ---------------------------------------------------------------------------- | | `.env.example` | Complete safe template with comments, defaults, and labeled placeholders | | `src/config/environment.js` | Parsing, coercion, allowlisting, cross-field validation, freezing, redaction | | `src/config/constants.js` | Configuration enums, redaction constants, root resolution, deep freeze | | `src/config/index.js` | Complete configuration composition and file/process loading | | Nine focused config factories | App, database, Telegram, sessions, Redis, queue, security, upload, logging | | `bin/verify-environment.js` | Human or JSON readiness report with non-zero failure status | | Unit/integration tests | Valid, invalid, placeholder, duplicate, CLI, production, and redaction cases | | Environment operator guide | Safe setup, key ownership, production rules, precedence, and troubleshooting | ## 3. Validation model The parser accepts only declared names and converts textual environment values into typed booleans, integers, arrays, URLs, or constrained strings. It checks individual values and relationships between values. Security-relevant checks include: - No example placeholder is accepted in runtime mode. - Duplicate keys and unknown file keys are rejected. - Secret lengths, format, diversity, and accidental reuse are checked. - Telegram token, username, webhook path, and webhook secret formats are checked. - The Mini App URL and primary application URL must share an origin. - Production uses HTTPS, deployable hostnames, explicit proxy trust, secure cookies, Redis-backed rate limiting, and structured logs. - Redis TLS certificates cannot be disabled for production `rediss:` connections. - CORS must contain the application origin and the production Telegram API base stays official. - Session idle/absolute TTL relationships are valid. - Upload roots and subdirectories cannot escape or overlap. - Request, connection, queue, file, pixel, and retention values have safe bounds. Successful parsing produces deeply frozen data. Focused modules do not read `process.env` themselves. ## 4. Secret handling The project contains no real `.env` or credential. Thirteen environment names are explicitly sensitive, while nested diagnostic redaction also detects token, password, secret, cookie, authorization, key, DSN, and bootstrap identity fields. The CLI reports invalid key names and validation messages without echoing their submitted values. JSON diagnostic previews replace sensitive values with `[REDACTED]` and absent sensitive values with `[NOT SET]`. ## 5. Financial and identity precision The database configuration prepares future MySQL drivers to use `utf8mb4`, return big integers as strings, and avoid automatic decimal conversion. This preserves the Phase 1 rules: - Telegram IDs use MySQL `BIGINT` and JavaScript strings. - Money uses `amount_minor BIGINT` and JavaScript strings/BigInt-safe logic. - Floating-point values are not an authoritative balance representation. No wallet calculation or ledger behavior is implemented prematurely. ## 6. Test coverage The automated suite covers: - Template completeness and template-mode validation. - Valid production parsing and type coercion. - Deep freezing across composed configuration. - Module mapping and bigint-safe database options. - Placeholder rejection without value disclosure. - Unsafe production transport, proxy, cache, logging, cookie, Redis TLS, and API choices. - Invalid TTL and upload directory relationships. - Path traversal, unknown keys, and duplicate keys. - Environment file override rules and unrelated process-variable filtering. - Flat and nested diagnostic redaction. - CLI success for template and valid runtime values. - CLI failure when `.env.example` is incorrectly used as runtime configuration. - Existing project structure, package, runtime, and fail-closed entry-point guarantees. ## 7. Configuration ownership decision Only technical deployment values live in environment configuration. App name, logo, language, display timezone, currency, themes, feature flags, content, task rules, referral rules, withdrawal rules, and user-facing messages remain database-backed Admin settings for later phases. This prevents runtime secret management from becoming an Admin Panel feature and avoids duplicating business settings across two sources of truth. ## 8. Quality gate The Phase 3 gate runs, in order: 1. ESLint with zero warnings. 2. Prettier check. 3. Automated tests. 4. Safe template verification. 5. Both local CSS builds. 6. Project layout and package verification. Registry audits and a clean-install dry run are also performed before the release archive is produced. Audit results describe registry state at the recorded verification time and should be rerun before every deployment. Verification evidence: ```text directories: 77 required files: 51 npm scripts: 23 environment keys: 77/77 tests: 21 passed, 0 failed npm audit: 0 known vulnerabilities npm audit --omit=dev: 0 known vulnerabilities npm ci --dry-run: passed placeholder runtime test: rejected safely with exit status 1 ``` Integrity checksums at Phase 3 completion: ```text 6f7cbea5e4a378b35c8a9864ed6d6e6479afa04c658044caaac0af8c390d02d2 package.json c58251c227a21d29211949a168bdd804b4030a82499d413251ff7edad617ef8d package-lock.json da469af1703964185b6ced06a1e351be5394586a30f9c236deb7b45a0349551a .env.example fc4b3998718ec8ddb1228fb57568e4a80e4306c5e7e27612246379ea088ce5c7 public/miniapp/css/app.min.css 1e885f8f83b7b568673ad4ee96128a66e35b4631fab817be55e1317c1082a5b7 public/admin/css/admin.min.css ``` ## 9. Explicit deferrals - MySQL driver, migrations, schema, and seed execution: Phase 4. - Express application bootstrap and infrastructure health checks: Phase 5. - Security middleware and Redis rate-limit implementation: Phase 6. - Telegram authentication and bot connectivity: Phase 7. - Admin authentication and one-time bootstrap use: Phase 8. - Queue/worker and scheduler connections: Phase 16. All corresponding commands continue to fail explicitly until their owning phase. ## 10. Phase 4 handoff Phase 4 can import validated `database` configuration without reading raw environment variables. It should add the MySQL driver, migration metadata, transactional migration runner, ordered SQL migrations, constrained indexes, rollback policy, idempotent seeds, and schema documentation. Live connectivity must include clear errors and must never print credentials. **Phase 3 status: COMPLETE AND VERIFIED.**
