Four context authorities, four jobs
Session Manager
Current work state, checkpoints and handoffs.
AI Memory
Durable decisions and reusable lessons.
Knowledge base
Curated project contracts and documentation.
Manager Context Graph
Opt-in conversation evidence linked to repository, thread, session and task identities.
Context-compaction recovery
The manager can search for an earlier decision, recover a bounded transcript range around it and follow deterministic relations. This does not pretend the context window is infinite; it makes prior evidence recoverable when needed.
Repository isolation
Context is stored under the repository's own .aiworkhub/ authority. A chat may switch repositories, but retrieval remains bound to the repository currently verified by the runtime.
Observable context economics
Requested context, delivered bytes, truncation and acknowledged receipts are measured independently. That creates a foundation for real tool ablation and token-economy benchmarks.
