### `agent/pre-step` — serial
### `agent/post-step` — serial
Awaited serial checkpoint for session-surface mutation after prompt assembly and before `step/start`; appends land outside the pending step. The loop derives history once afterward, so compaction records and replacements are included without rewriting an assembled request. The prompt and prefix are the exact pressure inputs for that request, and `signal` cancels listener work. Scope-filtered dispatch (`@deepseek-ai/dsh-scope`): agent-scoped listeners receive only that agent.
Awaited serial checkpoint after the response, real or synthetic tool results, injected context, and steering are durable but before `step/end`. A cancelled tool batch reaches this checkpoint with an aborted signal.

### `agent/session-prefix` — waterfall
Compose request-only messages placed before derived history. The frozen result is computed once per loop instance, logged on its anchoring request header, and reused so the provider prefix remains stable. Interrupted composition is discarded. Composition precedes the first `agent/pre-step` and request boundary, so listener appends join the current request and pressure accounting sees the composed prefix. Changing context belongs in history; contributors should prepend to `await next()` to preserve registration order. Scope-filtered dispatch (`@deepseek-ai/dsh-scope`): agent-scoped listeners receive only that agent.
