Access stays within a named scope.
designedBefore work begins, the permitted sources, users, actions, and systems are named. Gavin does not assume access beyond that scope.
Manufacturing work carries sensitive drawings, commercial terms, and decisions. Gavin is designed to use named sources and actions, keep evidence traceable, and leave approval and release with the responsible person.

The data, system, and action boundaries are confirmed for each deployment. These principles show what remains visible and who remains responsible.
Before work begins, the permitted sources, users, actions, and systems are named. Gavin does not assume access beyond that scope.
Gavin prepares drafts and presents open decisions. A named person approves controlled outputs and any external release.
Prepared requirements are designed to retain the originating file, revision, exact excerpt, owner, and checked time.
Receipts record what changed, who reviewed it, which drafts were affected, and what was not done.
For each deployment, the systems, objects, read/write direction, and writeback owner are named.
A correction records its scope, version, and approval owner. A check confirms that established work still behaves as expected.

We'll define the permitted data, users, systems, read/write direction, writeback owner, retention needs, and approval points for the deployment you are considering.
