The door
How an engagement starts.
Not a sprint slogan. Four thresholds. You can see each one. Nothing crosses the lintel until it is named in writing.
Threshold
01
Discover
The work, the constraints, who must approve. We listen before we propose a shape.
A shared picture. Not a contract.
Threshold
02
Write
Scope, the security bar, and delivery. In writing. Holdable. The other side can take it to a committee.
The file. Nothing is committed until this exists.
Threshold
03
Build
The system as scoped. Platforms, operations, hardening, a module, or counsel that stays counsel. The bar is already in the file.
Visible checkpoints. No black box.
Threshold
04
Hand over
Documentation, knowledge, and what remains named. Support after launch is scoped, not implied.
The keys. The record.
Discovery is a conversation. A file is a commitment. We do not start a build from a slide.
