# `Agentic.Loop.Stages.HumanCheckpoint`

Human-in-the-loop yield stage for :turn_by_turn mode.

Only active when `ctx.mode == :turn_by_turn`. Sits after ModeRouter in the pipeline.

When `ctx.phase == :review` and the agent produced text (not tool calls):
builds a proposal map from the response and calls the `:on_human_input` callback.

The callback returns:
- `{:approve, ctx}` — proceed as proposed
- `{:approve, feedback, ctx}` — proceed but incorporate feedback
- `{:abort, reason}` — stop the loop, return partial results

When `ctx.phase == :execute` — pass through (tools should execute normally).
