Öndery 4060cd1440 fix(agent): Await Response pauses on every Loop iteration (#16794)
## What

An **Await Response** (`UserFillUp`) node placed inside a **Loop** now
pauses and waits for a fresh user response on **every** iteration,
instead of only on the first one.

## Problem

When a `UserFillUp` node lives inside a `Loop`, it only paused for input
on the first iteration. On subsequent iterations the loop ran straight
through, silently reusing the answer the user gave the first time.

Root cause is in `UserFillUp._invoke` / the canvas wait-check
(`agent/canvas.py`). The wait-check decides whether to pause by calling
`Canvas._is_input_field_satisfied` on the node's form fields — a field
counts as satisfied as soon as its `value` is not `None`:

```python
@staticmethod
def _is_input_field_satisfied(field):
    ...
    if value is None:
        return False
    return True
```

The same component object is reused across loop iterations, and
`UserFillUp._invoke` writes the answer into
`self._param.inputs[...]["value"]` via `set_input_value`. Nothing
cleared those values when the node was re-entered for the next
iteration, so:

| Iteration | Entry (no answer yet) | Field value | Satisfied? | Result
|
|---|---|---|---|---|
| 1 | fresh | `None` | no | pauses  |
| 1 | resume w/ answer | `answer` | yes | continues  |
| 2 | fresh | `answer` (**stale**) | yes | continues  (should pause) |

## Fix

When a `UserFillUp` is entered without a fresh user answer
(`merged_inputs` is empty), clear the retained form values so the
wait-check treats the form as unsatisfied and pauses again:

```python
merged_inputs = self._merge_runtime_inputs(kwargs.get("inputs", {}))
if not merged_inputs:
    self._clear_form_values()
```

- Fresh entry / new loop iteration → no answer supplied → values cleared
→ node pauses and waits.
- Resume with an answer → `merged_inputs` is non-empty → values applied
normally, nothing cleared.
- Non-loop behavior is unchanged: the first entry already had `None`
values, so clearing is a no-op there.

`Begin` overrides `_invoke` and is unaffected.

## Tests

Added to
`test/testcases/test_web_api/test_canvas_app/test_fillup_unit.py`:

- `test_user_fillup_clears_stale_values_on_reentry_without_answer` — a
retained value is cleared on a fresh entry with no answer (loop
re-entry).
- `test_user_fillup_keeps_values_when_answer_supplied` — a supplied
answer is applied and not cleared.

All unit tests pass and `ruff check` is clean.

## Scope

This targets the Python agent runtime (`agent/`). It is independent of
any other in-flight Await Response change.

(1). Deploy RAGFlow services and images

https://ragflow.io/docs/build_docker_image

(2). Configure the required environment for testing

Install Python dependencies (including test dependencies):

uv sync --python 3.13 --only-group test --no-default-groups --frozen

Activate the environment:

source .venv/bin/activate

Install SDK:

uv pip install sdk/python

Modify the .env file: Add the following code:

COMPOSE_PROFILES=${COMPOSE_PROFILES},tei-cpu
TEI_MODEL=BAAI/bge-small-en-v1.5
RAGFLOW_IMAGE=infiniflow/ragflow:v0.26.4 #Replace with the image you are using

Start the containerwait two minutes:

docker compose -f docker/docker-compose.yml up -d


(3). Test Elasticsearch

a) Run sdk tests against Elasticsearch:

export HTTP_API_TEST_LEVEL=p2
export HOST_ADDRESS=http://127.0.0.1:9380  # Ensure that this port is the API port mapped to your localhost
pytest -s --tb=short --level=${HTTP_API_TEST_LEVEL} test/testcases/test_sdk_api

b) Run http api tests against Elasticsearch:

pytest -s --tb=short --level=${HTTP_API_TEST_LEVEL} test/testcases/test_http_api


(4). Test Infinity

Modify the .env file:

DOC_ENGINE=${DOC_ENGINE:-infinity}

Start the container:

docker compose -f docker/docker-compose.yml down -v
docker compose -f docker/docker-compose.yml up -d

a) Run sdk tests against Infinity:

DOC_ENGINE=infinity pytest -s --tb=short --level=${HTTP_API_TEST_LEVEL} test/testcases/test_sdk_api

b) Run http api tests against Infinity:

DOC_ENGINE=infinity pytest -s --tb=short --level=${HTTP_API_TEST_LEVEL} test/testcases/test_http_api
