OSS-first docs
These docs teach the open system first: contracts, generated surfaces, runtimes, governance, and incremental adoption. Studio shows up as the operating layer on top, not as the source of truth.
Session history buffer for the AI graph agent. Holds up to `capacity` turns (default 20, max 50).
Cost alignment
Capacity is bounded to keep context-window token costs within the per-session $0.50 ceiling defined in `m3-p0-ai-cost-ceiling.md`.
Fields
| field | description | |-------|-------------| | `sessionId` | Stable session identifier | | `history` | Ordered AiTurnState array (oldest first) | | `capacity` | Max retained turns before eviction | | `createdAt` | ISO 8601 timestamp when the session was created |
