Intent Mail: Full Email Platform in a Day — Gmail, Outlook, and a Rules Engine

Tue, 23 Dec 2025 10:00:00 -0600

35 commits in one repo. By the end of December 23rd, intent-mail was a working email platform with two provider connectors, full-text search, threaded send, attachment support, and a rules engine that could automate triage without touching the inbox until you said go.

The Storage Layer: SQLite + FTS5

Email data has two access patterns: exact lookup (give me this thread) and fuzzy search (find all emails about the deployment incident). SQLite handles the first pattern natively. FTS5 — SQLite’s full-text search extension — handles the second.

Local RAG NEXUS Upgrade and Nixtla Validation Infrastructure

Mon, 22 Dec 2025 10:00:00 -0600

December 22nd was a 35-commit day across four repos. The headline: local-rag-agent shipped a complete hybrid cloud architecture in 17 commits and a versioned release. Nixtla hardened its validation infrastructure. git-with-intent migrated its grading system to SQLite.

One of those days where every project moved forward.

NEXUS Hybrid Cloud Upgrade

The local-rag-agent had been locked to a single LLM provider since its inception. Anthropic’s Claude, hardcoded. That works for a personal tool. It doesn’t work when you want to run the same RAG pipeline against different providers for cost comparison, latency testing, or compliance reasons where certain data can’t leave a specific cloud tenant.

Lumera-Emanuel Launch and git-with-intent Open-Source Release

Sat, 20 Dec 2025 10:00:00 -0600

Two projects shipped on December 20th. One was brand new. The other opened its doors.

Lumera-Emanuel: Privacy-First Agent Memory

Lumera-Emanuel went from empty repo to working system in 11 commits. The goal: a privacy-first memory layer for AI agents that encrypts everything at rest and gives the agent structured recall without leaking user data to the host.

Encryption Layer

The core storage is SQLite with AES-256-GCM encryption. Every memory entry gets encrypted before it touches disk. The encryption key derives from a user-provided passphrase via PBKDF2 with a unique salt per entry. No plaintext ever persists.
