# Architecture Foundation Final Validation

## Scope validated

- canonical dashboard vertical modules and compatibility exports;
- low-risk API modules for catalogue lookups, content, support, and notifications;
- Communications ownership of Chat API and Chat/Call Socket registration;
- Scheduling ownership of cron persistence/runtime adapters;
- shared technical facades;
- worktree accountability and generated-artifact hygiene;
- frozen Auction schema.

## Auction freeze

`src/models/auctionModel.js` is outside the dirty worktree. Its recorded SHA-256 is:

```

No Auction schema, index, model, route contract, or lifecycle behavior is changed by this
architecture foundation.

## Authenticated browser smoke

The smoke ran 30 light/dark/compact/mobile scenarios over:

- `/dashboard/index`;
- `/dashboard/clients/all`;
- `/dashboard/settings`;
- `/dashboard/products`;
- `/dashboard/reasons`.

Results:

| Metric | Result |
|---|---:|
| horizontal overflow | 0 |
| broken images | 0 |
| duplicate IDs | 0 |
| console errors | 0 |
| failed HTTP/navigation requests | 0 |
| CSRF failures | 0 |
| table-alignment errors | 0 |
| theme leaks | 0 |
| debug artifacts | 0 |
| clipped leaf text | 28 |

All 28 clipped-text findings belong to Dashboard Home and correspond to existing
intentional `-webkit-line-clamp` rules for provider metadata and long latest-product
names. The architecture work did not touch Dashboard Home EJS/CSS/JS, and the QA script
was not modified to ignore these findings. This is a separate visual-policy debt, not an
architecture regression.

## Remaining gated work

- resolve or explicitly accept the Dashboard Home line-clamp policy;
- migrate auth/account identity only through its existing dedicated contract program;
- migrate Products mutations, Orders, Auctions, payments/wallet/settlement, and remaining
  realtime/cron business handlers only through domain-specific gates;
- retire compatibility exports only after all consumers use module public entries;
- adopt ESLint/Prettier only after package/config approval and a staged baseline.

The foundation must not be described as a complete whole-project rewrite while these
independent high-risk waves remain open.

## Automated gates
