# FieldOps Cloud - Gate 0 Architecture Compliance Audit

Date: 2026-06-16

Gate: 0 - Yii3 / Tech Stack / OOP Compliance Audit

## Verdict

GO for Gate 1 planning.

Gate 0 is approved after one QA-tooling fix cycle. The application remains aligned with the approved PHP/Yii3-component modular-monolith architecture. No duplicate framework, routing system, auth system, RBAC system, billing system, or `/admin` panel was found.

This is not a public-release GO. It only means the architecture and QA tooling gate is good enough to proceed to Gate 1.

## Compliance Table

| Area | Expected Standard | Current State | Compliant | Risk | Required Fix |
| --- | --- | --- | --- | --- | --- |
| Core stack | PHP 8.1+, Composer, Yii3 components, PSR-4 | `composer.json` requires PHP `>=8.1`, `yiisoft/router-fastroute`, `yiisoft/db-mysql`, `yiisoft/di`, `yiisoft/view`, PSR-4 `FieldOps\\` | Yes | Low | None for Gate 0 |
| Yii3-style architecture | Yii-style modular architecture without Yii2 idioms | Modular `src/*/{Controller,Service,Repository}` structure; no `Yii::$app` found | Yes | Low | Continue avoiding Yii2 patterns |
| Front controller | Single custom front controller | `public/index.php` owns bootstrap, dependency construction, and route table | Yes | Medium | Long-term: reduce bootstrap size with a container/factory module |
| Routing | Central route table; no duplicate routing | Active route table is in `public/index.php`; `config/web/routes.php` is empty | Yes | Low | None |
| Controller/service/repository layering | HTTP in controllers, business rules in services, persistence in repositories | Clients, jobs, quotes, invoices, team, billing, portal, recurring, inventory use repositories/services | Partial | Medium | Refactor largest controllers/services during later hardening, not before Gate 1 |
| OOP quality | Small classes, no god classes, limited global/session leakage | Some classes are large: `OperationsController` 684 lines, `JobController` 564, `BillingScheduleService` 944 | Partial | Medium | Add refactor ticket after release-critical gates are closed |
| Views | Escaped output; no DB/business logic in views | Templates use escaping; no DB access found in templates. `templates/layouts/main.php` instantiates `RbacService` for nav visibility | Partial | Low | Later: pass navigation permissions from controller/layout context |
| Production repositories | Production mode uses DB repositories; demo may use demo repositories | `public/index.php` switches to DB repositories when demo is disabled for core modules | Partial, improved by Gates 14-15 | Medium | Gate 14 moved SaaS admin pricing/tenant actions to DB repositories; Gate 15 moved schedule appointments to a DB repository. Remaining demo/session-backed paths require continuing audit. |
| Tenant isolation | Tenant-owned reads/writes scoped by tenant_id | Repositories use `tenant_id` filters; tests/smokes include tenant negative checks | Partial | High | Gate 3 must expand MySQL-backed tenant isolation across every module |
| Auth/security | Central auth, RBAC, CSRF, CSP/security headers, password hashing | `SessionAuth`, `RbacService`, `CsrfService`, `SecurityHeaderService`, `PasswordHasher` present and tested | Yes | Medium | Add deeper API/upload/rate-limit/security testing in later gates |
| Demo boundaries | Demo disabled in production | Production auth smoke confirms demo routes return 403 when `APP_ENV=production` and `DEMO_ENABLED=0` | Yes | Low | None |
| Platform admin | Protected platform admin, no duplicate `/admin` | `/platform-admin` is protected by RBAC; no `/admin` panel found | Yes | Low | None |
| Customer portal | Tokenized portal access | Signed tokens and durable token repositories exist; invalid/expired tokens tested | Partial | Medium | Later: production portal payment/approval flow coverage and live payment truth audit |
| Billing architecture | Existing pricing/subscription/billing systems reused | Platform pricing/billing services exist; no duplicate pricing system found | Partial | Medium | Gate 5 must decide live Stripe/payments or manual/planned labelling |
| Integration truthfulness | Live integrations must not be implied if sandbox only | Gate 6 now marks accounting/calendar/LLM as contract tested but not live; settings pages show readiness and provider contract coverage | Yes for foundation | Medium | Live provider activation remains blocked until credentials, encrypted token/key storage, webhook verification, workers, and downstream tests are complete |
| Mobile/PWA | PWA, service worker, offline tech foundation, Capacitor strategy | `manifest.webmanifest`, `service-worker.js`, offline route/API, Capacitor config/docs exist | Partial | Medium | Gate 12/13 must validate install/offline/native builds on devices |
| QA tooling | `composer test`, `composer check`, route inventory, browser smoke, auth smoke, workflow smoke function | All passed after smoke harness schema fix | Yes | Low | Keep QA smoke schema aligned with production repositories |
| Release docs | Commands/testing/release docs maintained | Strong docs exist, but some Yii foundation docs/tools are missing or differently named (`PROJECT_MAP.md`, `THREAT_MODEL.md`, `tools/run-checks.php`) | Partial | Low | Add docs/tooling normalization ticket before final release gate |

## Scores

| Score Area | Score | Notes |
| --- | ---: | --- |
| Yii3 Compliance | 8/10 | Yii3 components and PHP modular architecture are intact; no framework drift found |
| OOP Compliance | 7/10 | Good class boundaries, but several large controllers/services need later refactoring |
| Service Layer Compliance | 8/10 | Core entities use repositories/services; some demo/session-backed production gaps remain |
| Security Compliance | 7/10 | Central auth/RBAC/CSRF/CSP pass; API/upload/rate-limit/live integration security still needs later gates |
| Tenant Isolation Compliance | 6/10 | Current tests pass, but full MySQL-backed cross-module isolation is still Gate 3 work |
| Release Architecture Compliance | 7/10 | Architecture is stable enough to continue, but production/live integration/mobile/deployment gates are still open |

## Findings

### Fixed During Gate 0

| ID | Severity | Finding | Fix | Verification |
| --- | --- | --- | --- | --- |
| G0-001 | P1 | `tools/production-workflow-smoke.cjs` temporary production DB lacked `job_field_notes`, causing job detail fatal during workflow smoke | Added `job_field_notes` and `job_field_note_versions` table setup | Production workflow smoke passed with `failureCount: 0` |
| G0-002 | P2 | Production workflow smoke expected old invoice edit heading `Edit Unpaid Invoice` | Updated expected heading to `Edit Invoice` | Production workflow smoke passed |
| G0-003 | P1 | Temporary production DB lacked portal token/message log tables after job detail started checking portal links | Added `customer_portal_tokens` and `customer_message_logs` table setup | Production workflow smoke passed |

### Open Gate 0 Follow-Ups

| ID | Severity | Finding | Impact | Recommended Gate |
| --- | --- | --- | --- | --- |
| G0-004 | P2 | Several controllers/services are large | Maintainability risk, slower future changes | Gate 14 or post-P1 hardening |
| G0-005 | P2 | Some production paths still use demo/session-backed repositories or placeholders | Public release must not imply durability where none exists | Gates 2, 3, 5, 6 |
| G0-006 | P2 | Yii foundation docs/tools are not fully normalized to expected names | Agent/release handoff friction | Gate 10 |

## Verification Evidence

Passed:

```powershell
composer test
$env:COMPOSER_PROCESS_TIMEOUT='0'; composer check
composer audit
```

Passed browser/local smokes:

```powershell
tools/browser-smoke.cjs
tools/role-walkthrough.cjs
tools/auth-production-smoke.cjs
tools/production-workflow-smoke.cjs
```

Key results:

- Browser smoke: `failureCount: 0`
- Role walkthrough: `failureCount: 0`
- Production auth smoke: `failureCount: 0`
- Production workflow smoke: `failureCount: 0`
- Route/action inventory: 116 routes, 208 links, 65 form/actions, 92 buttons, 0 findings
- Dependency audit: no security vulnerability advisories found

## Gate 0 Decision

Verdict: GO.

Approved to proceed to Gate 1 - Close All P0 / P1 Issues.

Do not proceed past Gate 1 until P0/P1 issue review, retest, and approval are complete.
