The Engineering Manifesto

7 Non-Negotiable Operational Principles for Sovereign Software Systems

v20.0 (2026)

§1

Via Negativa (Anti-Waste Directive)

«Never automate what should be deleted.»

If switching costs exceed savings, automation is forbidden.

Before writing a line of code or deploying a database table — decide whether the problem can be deleted entirely. A deleted process requires no support, no monitoring, no migrations. Automating a broken process immortalizes it.

§2

Zero SaaS Taxes

«Self-hosted open-source over recurring seat licenses.»

Every SaaS seat is a tax that outgrows your business.

We build on a self-hosted open-source stack: PostgreSQL, Next.js, Twenty CRM, Trigger.dev v3. You pay for infrastructure (tens of dollars), not licenses (hundreds and thousands). No vendor lock-in: the complete Git repository and private infrastructure remain yours.

§3

Strict Schema-First (DDL + Zod)

«Deterministic validation over vibe-coding slop.»

Contract first: DDL schema and Zod schemas. Code comes second.

Every entity starts as a schema: SQL DDL for data, Zod for API and content contracts. Validation at the boundaries (build-time and runtime) makes the 'wrong data' error class impossible rather than probable.

§4

Async-First Velocity

«Asynchronous Loom walkthroughs over daily status calls.»

Zero meeting fatigue: communication in writing and video; synchronous only for decisions.

Status calls burn the most expensive resources — focus and context. We run on written updates, Loom videos, and a task tracker. Synchronous meetings are reserved for decisions that cannot be made asynchronously.

§5

100% Code & Data Sovereignty

«Complete Git repo transfer and private infrastructure ownership.»

No rented data: you own 100% of the code, schemas, and data.

Upon milestone completion you receive the complete Git repository, DDL migrations, and infrastructure runbooks. Your customers, orders, and analytics live in your own database — no platform can revoke access to your business.

§6

Single Production Leases & Memory Fencing

«Docker resource fencing against out-of-memory cascading failures.»

One production lease per service; hard memory limits per container.

Each service lives in its own Docker container with a memory fence: an OOM in one service never takes down its neighbors. One production lease per service makes rollback, migrations, and targeted restarts possible without full-system downtime.

§7

Fixed-Scope Knife & Escrow Protection

«Mutual protection via third-party escrow and fixed timeboxes.»

Fixed fee, fixed scope, funds in escrow until acceptance.

No hourly meters and fuzzy estimates. Every milestone has a fixed scope and fixed price; funds are frozen in escrow and released after your acceptance. This protects both sides: you never pay for process, we never work in an unbounded deadline.
