Ladder `low \| medium \| high \| xhigh \| max` (`ReasoningEffort` in `@dispatch/wire`). Resolution per turn: `ChatRequest.reasoningEffort` override → persisted per-conversation value → default `high`. Each provider maps a level to its native knob in its own code (e.g. Anthropic `thinking.budget_tokens`); providers without such a knob ignore it. | thinking level, effort level, thinking budget (that's the provider-NATIVE knob a level maps to) | | **context size** | The number of tokens a conversation currently occupies: the most recent turn's FINAL step `inputTokens + outputTokens` (NOT the aggregate per-turn `usage`, which sums per-step prompts and overcounts a multi-step turn). Stamped on `TurnDoneEvent.contextSize` (live) + `TurnMetrics.contextSize` (persisted); a client reads the LATEST turn's value as current usage.
