[Concept] The Generational Context Architecture (GCA)

I think several replies above already point in the right direction, especially the distinction between handoff, persistence, governance, and durable authority. The point I would make sharper is this: GCA intervenes too late. A generational handoff starts after the working context has already grown, degraded, accumulated weak assumptions, mixed evidence with interpretation, and forced the model to operate inside an increasingly polluted context. The handoff then tries to rescue that state by summarizing or transferring it. In my experience, that class of solution never becomes fully satisfactory, because the damage is already upstream. The deeper architectural issue is not only how to pass context from one generation to the next. It is how to prevent the wrong material from entering the working context in the first place. So I would separate two approaches: 1. Late recovery: long context → degradation → summary/handoff → successor 2. Upstream state governance: claims/evidence/constraints/conflicts are maintained outside the transcript → only a task-relevant state slice is projected into the working context The second approach is much stronger for token efficiency and reliability. It treats the transcript as raw material, not as memory. The durable layer contains structured state, provenance, rejected paths, open conflicts, constraints, and evidence. The agent then reasons over a selected projection of that state. A handoff file can still be useful, but only as a compact read model over a governed state. It should not be the memory system itself. Otherwise each generation inherits a plausible compressed narrative of the previous generation’s drift.
