### What problem does this PR solve?
`POST /api/v1/agents/rerun` loaded a pipeline operation log by UUID via
`PipelineOperationLogService.get_documents_info` with no authorization,
then wiped chunks, reset document counters, deleted tasks, and re-queued
dataflow for the victim document.
Any authenticated user who knew a victim's pipeline log id could disrupt
parsing on documents they did not own.

### Security notes
- **CWE-639:** Closes cross-tenant pipeline rerun / chunk wipe via
leaked log UUID.
- `tenant_id` from `@add_tenant_id_to_kwargs` is `current_user.id`;
`DocumentService.accessible` covers team-shared KBs.

## Summary
- **Backend**: `_iter_session_completion_events` in `agent_api.py` was
filtering out `user_inputs` and `workflow_finished` SSE events, causing
agents with UserFillUp components to silently fail in explore mode — the
interactive form never appeared, while the same agent worked correctly
in run (editor) mode.
- **Frontend**: `SessionChat` component in explore mode was missing
`DebugContent` children rendering inside `MessageItem`, so even if the
backend forwarded the events, the form UI would not render. Added
`DebugContent`, `MarkdownContent`, `useAwaitCompentData` hook, and
input-disabling logic to match the run mode's `chat/box.tsx` behavior.
## What was changed
### Backend (`api/apps/restful_apis/agent_api.py`)
- Line 266: Added `"user_inputs"` and `"workflow_finished"` to the
allowed event filter in `_iter_session_completion_events`
### Frontend (`web/src/pages/agent/explore/components/session-chat.tsx`)
- Added imports: `DebugContent`, `MarkdownContent`,
`useAwaitCompentData`, `useParams`
- Added `sendFormMessage` from `useSendSessionMessage()` hook
- Added `useAwaitCompentData` hook for form state management
- Added `DebugContent` as `MessageItem` children for the latest
assistant message (renders UserFillUp form)
- Added `MarkdownContent` + submitted values display for previous
assistant messages
- Updated `NextMessageInput` disabled states to respect `isWaitting`
(form submission in progress)
## Test plan
- [x] Agent with UserFillUp component (e.g., email draft with
send/edit/cancel options) shows interactive form in **explore mode**
- [x] Same agent continues to work correctly in **run (editor) mode**
- [x] Form submission sends data back to the agent and workflow
continues
- [x] Input field is disabled while waiting for form submission
- [ ] Agents without UserFillUp components are unaffected in explore
mode

### What problem does this PR solve?
Fixes#15456.
The SDK agent-bot routes `POST /api/v1/agentbots/<agent_id>/completions`
and `GET /api/v1/agentbots/<agent_id>/inputs`
(`api/apps/restful_apis/bot_api.py`) authenticate the caller with a beta
API token — which only yields the caller's `tenant_id` — but then load
and run the agent named in the URL **without verifying the agent belongs
to the caller's tenant**. `UserCanvasService.get_agent_dsl_with_release`
even accepts a `tenant_id` it never uses, and `begin_inputs` calls
`get_by_id` directly. Any holder of a single valid beta token could
therefore run another tenant's agent (leaking its DSL/prompts/tool
config) or read another tenant's agent metadata and begin input form,
just by substituting a victim `agent_id`.
This PR adds the project's existing ownership gate,
`UserCanvasService.accessible(agent_id, tenant_id)`, to both endpoints
right after token authentication — mirroring the checks already enforced
on the equivalent first-party routes in
`api/apps/restful_apis/agent_api.py` (lines 75/578/775) and on the
sibling `chatbot_completions` / `create_agent_session` /
`delete_agent_session` handlers in the same file. On failure it returns
the same `Can't find agent by ID: <id>` message already used by
`begin_inputs`, so it does not reveal whether an `agent_id` exists in
another tenant.
Added a regression test
(`test/unit_test/api/apps/restful_apis/test_agentbots_access_control.py`,
following the existing stubbed-loader pattern from
`test_get_agent_session.py`) asserting that an inaccessible `agent_id`
is rejected before the agent is loaded (`begin_inputs`) or executed
(`completions`), and that an accessible agent still proceeds.

### What problem does this PR solve?
`GET` and `DELETE` `/api/v1/agents/<agent_id>/sessions/<session_id>`
verified canvas access for `agent_id` in the URL but loaded/deleted
sessions only by `session_id`, without checking `conv.dialog_id ==
agent_id`.
Any user with access to **any** agent could read or delete another
agent's `API4Conversation` session (messages, references, DSL, etc.)
when they knew the session UUID.
Agent completions in the same file already enforce this binding; chat
sessions do too — these two routes were inconsistent.

routes.
- Covers `GET /api/v1/datasets/<dataset_id>/documents/<document_id>` and

### Type of change

## Summary
Restore the `DocumentService.accessible(doc_id, current_user.id)` check
that PR #15146 dropped from the REST document preview handler. Any
authenticated caller could download any tenant's document bytes by
guessing/knowing the `doc_id`.
## Root cause
`api/apps/restful_apis/document_api.py` — the `GET
/documents/<doc_id>/preview` handler called `DocumentService.get_by_id`
and went straight to `File2DocumentService.get_storage_address` +
`STORAGE_IMPL.get`, with no tenant check between the lookup and the
read. The handler's docstring even promises "user must belong to the
tenant that owns the document's knowledge base" — the code didn't
enforce it.
## Fix
- Add `current_user` to the existing `api.apps` import.
- Immediately after `get_by_id`, call
`DocumentService.accessible(doc_id, current_user.id)`; on denial, return
the **same** `get_data_error_result(message="Document not found!")`
shape used for the missing-doc branch. That makes a cross-tenant probe
indistinguishable from a missing-doc probe, preventing ID enumeration
(the issue body calls this out explicitly).
- Emit `logging.warning` with caller user + doc_id for audit.
- Restores symmetry with peer routes that already call
`accessible(doc_id, user_id)` (e.g. `_run_sync` at
`document_api.py:1380`).
## Test plan
Adds
`test/unit_test/api/apps/restful_apis/test_document_preview_accessible.py`:
- **`test_cross_tenant_preview_is_denied`** — owner tenant ≠ caller
tenant; asserts the response shape is `Document not found!` and the
storage backend (`thread_pool_exec(STORAGE_IMPL.get, ...)`) is **never**
invoked.
- **`test_missing_doc_returns_not_found`** — missing-doc behaviour
unchanged.
Stub-loader pattern mirrors
`test/unit_test/api/apps/sdk/test_dify_retrieval.py` (added in #15028,
passing in CI).
## Provenance — how this fix was produced
This PR was authored against a small cited knowledge base committed in
the working tree as a `.vouch/` (see
[vouchdev/vouch](https://github.com/vouchdev/vouch)). The loop used
here:
1. **Grounding first.** Before reading the handler, queried the KB for
prior context: `vouch context "tenant scoped accessible authorization"`
→ retrieved a cited claim distilled from PR #15028 (which restored the
same `accessible()` check on `/dify/retrieval`). The retrieved rule:
> *ragflow REST endpoints that load by tenant-scoped id must call
`<Service>.accessible(id, tenant_id)` after `get_by_id` and before
storage/DB read; deny with code 109 'No authorization.' and log a
warning. Established by PR #15028.*
2. **Applied the pattern with a domain refinement.** For an API/JSON
endpoint, `No authorization.` is the right denial shape. For a
**byte-streaming, browser-facing** endpoint like `/preview`, leaking
*existence* itself enables enumeration — so per the issue's expected
behaviour, this PR denies with `Document not found!` (indistinguishable
from missing) instead. Same auth check, narrower response.
3. **Recorded the refinement back into the KB** as a new cited claim, so
the next IDOR-class issue starts already grounded in both the general
pattern and the byte-route nuance.
Net effect of the workflow: the fix replicates a known-good pattern
instead of reinventing it, *and* the place where the pattern was nuanced
is now retrievable for the next pass. Mechanism is fully independent of
this PR — it's not a runtime dependency, just process discipline.
Closes#15501
### What problem does this PR solve?
Fixes#15286.
When calling `/api/v1/openai/<chat_id>/chat/completions` with `"stream":
true`, the response contains the answer **twice** — the final message
repeats everything that was already streamed.
#### Root cause
RAGFlow's `async_chat` streams the body as incremental `delta.content`
chunks, then emits a terminating `final` event whose `answer` is the
**complete** (decorated) message. The handler re-emitted that full
answer as one more `delta.content` chunk:
```python
if ans.get("final"):
if ans.get("answer"):
full_content = ans["answer"]
response["choices"][0]["delta"]["content"] = full_content # <-- whole answer again
yield ...
```
So a client accumulating `delta.content` ends up with the message
duplicated.
#### Fix
Drop the re-emission. The complete answer from the `final` event is now
surfaced **only** through the trailing chunk's `final_content` and
`reference` fields, which matches OpenAI streaming semantics: deltas are
incremental, and the final chunk carries only `finish_reason` / `usage`
(plus RAGFlow's `reference` / `final_content` extensions).
This matches the expected behavior described in the issue: "The stream
should only yield content chunks once, and the final message should only
contain reference, usage, and finish_reason."
#### Testability refactor
The streaming SSE assembly was a closure inside the request handler, so
it could only be exercised against a live server + real LLM. I extracted
it into a module-level `_stream_chat_completion_sse` async generator
(behavior-preserving) so it can be unit-tested with a fake event stream.
#### Tests
Adds
`test/unit_test/api/apps/restful_apis/test_openai_stream_no_duplicate.py`
(same import-stub pattern as the existing `test_get_agent_session.py`):
- body is streamed exactly once (the regression);
- the complete answer is never re-emitted as a content chunk;
- the terminating chunk has `finish_reason="stop"`, `content=None`, and
correct `usage`;
- `final_content` / `reference` are present on the trailing chunk;
- reasoning (`think`) deltas stream separately and are not duplicated.
> Note: this is unrelated to #15442, which only changes the `stream`
default — it does not touch the duplication logic.

## Summary
Fixes#15245 — `POST /api/v1/chat/completions` with `stream=true`
intermittently returns 500:
```
data:{"code": 500, "message": "failed to encode response: json:
unsupported value: NaN (status code: 500)", "data": {...}}
```
…even though "the same question" works on retry.
## Root cause
The streaming path serialized the answer with bare `json.dumps(...)`
(`api/apps/restful_apis/chat_api.py:1221`). `json.dumps` defaults to
`allow_nan=True` and emits the literal token `NaN` for NaN /
Infinity float values. That is valid Python-flavored JSON but
**invalid per RFC 8259**, so downstream consumers reject it. The
reporter's gateway is Go-based and the error wording
(`failed to encode response: json: unsupported value: NaN`) is
straight from Go's `encoding/json`.
How NaN gets into the payload: retrieval scoring in
`rag/nlp/search.py` runs `np.mean(...)` over aggregations that can
be empty, and similarity denominators can be zero. Reference chunk
fields like `similarity`, `vector_similarity`, `term_similarity`
can therefore be NaN depending on which chunks a given query
retrieves — which is exactly why the failure is intermittent for
the same question.
The non-streaming branch (`get_json_result(data=answer)`,
`chat_api.py:1243`) has the same vulnerability — Quart's `jsonify`
also defaults to `allow_nan=True` and the same retrieval pipeline
feeds both branches.
`agent/tools/exesql.py:88-102` already has the same NaN/Inf guard
for SQL results. This PR brings the chat completions path up to
parity.
## Fix
Add a small `_sanitize_json_floats(obj)` helper near the top of
`api/apps/restful_apis/chat_api.py`. It walks `dict` / `list` /
`tuple` and replaces any `float` that is `NaN` or `±Infinity` with
`None`. Apply it at the two serialization boundaries:
- **Streaming branch** (`stream()`): sanitize the SSE payload before
`json.dumps`.
- **Non-streaming branch**: sanitize the `answer` dict before
`get_json_result(data=...)`.
The terminal `data:True` frame and the `code:500` error frame carry
no scores and are left untouched.
Added `import math` to the existing alphabetical import block.
No change to retrieval logic — replacing NaN with `null` at the
serialization boundary is conservative: clients still parse the
JSON, a missing-score chunk is a strictly better failure mode than
a 500 that kills the whole reply.
### Type of change
- [x] Bug Fix (non-breaking change which fixes an issue)
`GET /agents/<agent_id>/sessions/<session_id>` crashed with
`AttributeError: 'NoneType' object has no attribute 'to_dict'` when the
session lookup failed: `_, conv =
API4ConversationService.get_by_id(...)` returned `(False, None)`, then
`conv.to_dict()` was called unconditionally.
This is reachable in multi-instance deployments: the session row may not
yet be visible on the node servicing the immediate follow-up GET after a
session is created on a different node.
Add the same `if not exists` guard already used by every other call site
of `API4ConversationService.get_by_id` (see agent_api.py:1147,
sdk/session.py:179, conversation_service.py:248, canvas_service.py:323).
