### Turn Flow ### Turn Flow
```text ```text
queued input -> prompt admission -> turn/start choose declarative identity and fresh/resume path
-> [agent/step -> request -> chunks/message -> tools -> step/end]* -> prepare private session + agent.ctx -> await unpublished setup -> invoke optional synchronous setup commit
-> turn/end -> enter session + agent -> session/created -> agent/created
-> enable driving -> agent/session-start(source) -> start driver
forever:
wait for queued occurrence
claim (edit/remove end) -> emit agent/status(running) if starting an interval
open the next-step acceptance window
-> agent/prompt-submit
blocked or failed prompt -> close the window without opening a turn
append a context-only caller batch immediately
keep steering and context staged beside it pending for a later admitted turn
allowed prompt:
'turn/start'
append prompt + additional contexts as separate 'user/message' events
STEP loop:
agent/step
assemble system prompt and tools
materialize changed runtime context as sourced 'user/message'
drain injected context and provisional steering (steering bypasses prompt-submit)
snapshot the derived messages (the reconstruction boundary)
'step/start'
admit the drained steering receipts
agent/request (config only) -> prepare adapter defaults/provenance + context capacity under turn signal -> log request/header (+ request/context on route change) -> llm/stream (frozen, registration-bound)
'assistant/chunk'
'assistant/message'
schedule tool calls by ctx.tools.executionMode:
exclusive -> barrier
parallel -> rolling pool, <= maxParallelToolCalls; reclassify-at-start; scheduler failure -> stop starts, drain dispatches
start -> 'tool/call' -> ordered tools/pre-execute -> concurrent tools/execute
model-order result -> ordered tools/post-execute -> 'tool/result'
drain accepted tool context after all results; keep steering provisional
'step/end'
continue for tools or steering unless a result concluded the turn and rejects pending steering
otherwise agent/turn-stopping -> drain context -> continue only for steering
close the next-step acceptance window
'turn/end' -> agent/settled
start the next waking queued message, or emit agent/status(idle)
idle injection -> user/message idle inject:
append 'user/message'
do not open a turn or run the model
``` ```
Each step assembles the prompt, tools, runtime context, adapter settings, and model history before recording its reconstruction boundary. Tool calls then run through the shared execution pipeline. `inject()` adds context without opening an idle turn; `steer()` targets a next-step admission window; queued input remains the source of ordinary turns. The generated [agent lifecycle](agent-lifecycle.md) owns exact event order, and the [agent-loop README](../packages/core/agent-loop/README.md) owns queue, steering, retry, and cancellation mechanics.

每个步骤都会组装提示词、工具、运行时上下文、适配器设置和模型历史，随后记录其重建边界。之后，工具调用通过共享执行流水线运行。`inject()` 添加上下文但不打开空闲轮次；`steer()` 针对下一步骤的准入窗口；排队输入仍是普通轮次的来源。精确事件顺序由生成的 [agent 生命周期](agent-lifecycle.md)定义；队列、steering、重试与取消机制由 [agent-loop README](../packages/core/agent-loop/README.md)定义。 每个步骤都会组装提示词、工具、运行时上下文、适配器设置和模型历史，随后记录其重建边界。之后，工具调用通过共享执行流水线运行。`inject()` 添加上下文但不打开空闲轮次；`steer()` 针对下一步骤的准入窗口；排队输入仍是普通轮次的来源。精确事件顺序由生成的 [agent 生命周期](agent-lifecycle.md)定义；队列、steering、重试与取消机制由 [agent-loop README](../packages/core/agent-loop/README.md)定义。
