09.1
Follow the object
Professional work is organized around objects that persist: a scene, a model, a workbook, a timeline, a report. The interaction trace should stay connected to those objects.
File events provide the durable landmarks in a long session.
09.2
Snapshots, not just backups
An intermediate snapshot is a semantic checkpoint. It can mark a decision, preserve an alternative, or define the start of a new practice branch.
The value is not only recovery. It is the ability to inspect how the work evolved.
09.3
Capture structure
Folders, linked assets, application packages, and sidecar files often make up one deliverable. Capturing only the visible file can leave the result incomplete.
The recording layer should understand the working set, not just the last saved path.
09.4
Make change searchable
Once file state shares a clock with the session, reviewers can jump directly to saves, exports, renames, and large diffs.
That makes hours of expert work navigable without flattening it into a transcript.
