AI Core Upgrades: Vault, Contact, & Briefing Features

The AI core implemented a major encryption upgrade, moving from legacy Fernet methods to AES-256-GCM via a centralized VaultService and related migrations.

Proactive briefing capabilities were significantly enhanced by cross-capability features, including embedding email triage and integrating attendee context into meeting alerts.

Identity resolution was strengthened by indexing contact information from both IMAP and CalDAV, allowing LLMs to resolve names to email addresses.

The system improved calendar handling by adding deterministic free-time gap finding and proactive conflict alerts.

New user onboarding now includes connecting calendar and email providers to trigger an immediate, personalized welcome briefing.

Email ingestion saw major pipeline improvements: headers are now fetched incrementally, classified deterministically, and stored as knowledge facts.

Morning briefs were unified into a single digest covering both schedule and inbox activity, respecting local timezone and working hours.

Testing infrastructure was heavily modernized across multiple services, replacing hand-rolled or basic MagicMock implementations with real MemoryStore instances for production parity.
