Every merge should make the next one better
Completed work should leave useful knowledge behind, so future changes build on the repository's actual history.
The repository has something to teach
Every completed change contains information that can help the next one. An architectural boundary may become clearer. A local convention may turn out to matter in an unexpected place. A review may explain why an apparently simpler approach would have caused trouble elsewhere. Those lessons are part of the value of doing the work.
A sustained autonomous engineering system needs to carry useful knowledge forward. Descant's July work strengthened the connection between merged changes and the learning process, bringing the actual change and its pull-request context into that work. The aim is practical: future engineering should benefit from what the repository has already taught us.
Preserve decisions that help the next change
Useful learning is specific enough to guide action. It explains the boundary to preserve, the convention to follow, or the reason a decision was made. It should help an engineer approach the next task with better context and fewer repeated discoveries. The codebase and its history remain essential references as the system changes.
This also connects learning to review. A resolved finding can teach more than a correction to one line. It may clarify a pattern that applies across the repository. Carrying that reasoning forward gives the next change a better starting point, while keeping the standards rooted in the actual project.
Progress that compounds
This is central to the Descant we are building. An issue advances through planning, implementation, review, and merge; the result then improves the context for subsequent work. Across many changes, the product develops and the system becomes better informed about the codebase it is maintaining.
We use the next generation of Descant across our own projects to refine that approach under different demands. The lessons improve both the individual repositories and Descant itself. For teams, the ambition is a development system that becomes a more effective collaborator over sustained work, with human direction, architectural intent, and engineering standards carried forward from one change to the next.
