# Sprint 22 Status

## Completed

### Internal notifications

The release provides personal notification inboxes, summary counts, priorities, categories, source links, read/archive actions, deduplication and user-level preferences. Preferences include in-app delivery, email delivery, daily and weekly digests, quiet hours and timezone.

### SMTP and queued email

BCOS now stores authenticated SMTP configuration, encrypts passwords with the existing application key, renders governed templates and places outgoing messages into a persistent queue. The worker supports TLS, implicit SSL, SMTP LOGIN, multiple recipients, multipart text/HTML messages, exponential retry, maximum attempts, stale-lock recovery and delivery-attempt records.

### Collaboration

Project, client, direct, approval and general conversations support server-enforced membership, moderators, threaded messages, mentions, unread counts and clean-file attachment links. Message posting creates in-app notifications and, according to user preferences, queued email notices.

### Reminders, alerts and digests

The scheduler handles one-time and recurring reminders, compliance deadlines, statutory filings, licence expiry, policy reviews, contract expiry, daily digests and weekly digests.

### Responsive frontend

Three integration screens are supplied:

- `NotificationCentrePage`
- `CollaborationPage`
- `EmailAdministrationPage`

They include desktop, tablet and mobile layouts without mandatory horizontal scrolling.

## Not completed

The package does not yet provide browser push notifications, SMS, WhatsApp delivery, inbound email replies, bounce/complaint processing, email-open tracking, real-time WebSockets, a secure file-upload endpoint, virus scanning infrastructure or a full React-router merge. Those items are outside Sprint 22.

## Verification completed in the build environment

- 228 cumulative PHP unit/static checks passed.
- 39 focused Sprint 22 checks passed, including TypeScript compilation and a local SMTP transport/capture integration test.
- 96 PHP files passed syntax validation.
- The SMTP integration test used a local loopback test server; it did not contact an external provider.

## Testing limitations

- No live MySQL/MariaDB server or PDO MySQL driver was available in the build environment, so migration 016, views, queue locking and database authorization were not executed against a real database.
- No real company SMTP account was used. TLS certificate negotiation and authentication must be tested with the selected provider in staging.
- The supplied React screens passed a focused TypeScript compile check using local React type stubs, but the complete original React/Vite application was not compiled or browser-tested.
- No real email deliverability, SPF, DKIM, DMARC, bounce, throttling or provider-rate-limit test was possible.
- No production cron, concurrent worker load, large queue, mobile browser, accessibility or penetration test was performed.
