## Default Loop Lifecycle
The shipped loop drains work from prompt through checkpoint. Every pause is a service call or event available to plugins.
The shipped loop drains prompt-to-checkpoint work through plugin-visible services and events.
A **session** is an append-only event log. An ordinary **turn** claims one queued message; an injection turn claims none. A turn ends when the model stops asking for tools and no plugin requests continuation. A **step** is one model request plus its tool executions. In the flow below ([sequence companion](agent-lifecycle.md)), quoted names are durable session events and event names are extension points.
A **session** is an append-only log. Each ordinary **turn** claims one queued `send()` item; injection claims none. A claimed `send()` successor awaits the prior turn's checkpoint but may share its `running` interval ([decision](../.agents/notes/implemented/simplification/2026-07-17-one-send-one-turn.md)).

Startup resolves identity. No id mints `<config-id>-session-<uuid>`; `sessionId` resumes or creates; `resumeSessionId` requires history. Active failures emit `agent-loop/config-start-failed(sessionId, error)`, so front doors reject work; teardown stays silent.

checkpoint persistence and notify idle/running status

Each successful `send()` adds one FIFO item whose claimed turn contains no other ordinary message; consecutive claimed items wait for the prior ordinary turn's checkpoint to settle, but can share one `running` interval ([decision](../.agents/notes/implemented/simplification/2026-07-17-one-send-one-turn.md)). Cancellation, disposal, or a pre-start failure may drop an item without a turn. Each step assembles ordered prompt sections, tool schemas, and `{{name}}` variables; unknown or valueless references fail the turn. `dsh-system-prompt` owns the harness identity and default persona, which an agent scope may shadow. The loop supplies `model` and `cwd` ([prompt ownership](../.agents/notes/implemented/architecture/2026-07-05-prompt-variables-and-tool-guidance-ownership.md)).

Tool-time context—including async `agent.inject()` notices and post-tool `additionalContexts`—settles, then follows recorded results. Steering drains before `agent/post-step`, which observes durable output, results, context, and steering before signal closure. Leftovers become queued input. Terminal `agent/turn-stop` runs after continuation and steering folding, stays authoritative through turn close and flush, and discards later steering but preserves queued prompts.
