Docs: make chat unbounded-scan plan self-contained

Inline the bug diagnosis into a Background section and drop references
to the now-deleted CHAT_UNBOUNDED_DOCUMENT_SCAN.md and the throwaway
worktree, so the plan can be executed on its own.

+# Chat Unbounded Document Scan Fix Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Stop `ChatStreamingView`'s "chat with my whole archive" path from materializing every accessible `Document` into Python memory on every chat message; bound the cost to the vector-store `IN`-filter id list plus at most `CHAT_RETRIEVER_TOP_K` (5) documents for the reference/permission lookup.
+
+**Architecture:** Change `documents` from a materialized `list[Document]` to a lazy `QuerySet[Document]` threaded through `ChatStreamingView.post` -> `stream_chat_with_documents` -> `_stream_chat_with_documents` -> `_get_document_references`. Build the vector-store `IN` filter from `documents.values_list("pk", flat=True)` (ids only, no row hydration) instead of iterating full `Document` instances. Reorder `_get_document_references` to run `retriever.retrieve()` first, then permission-check/hydrate only the (≤5) documents that `top_nodes` actually reference via `documents.filter(pk__in=candidate_ids)`, instead of hydrating every accessible document up front.
+
+**Tech Stack:** Django ORM (QuerySet), llama-index (`MetadataFilters`, `VectorIndexRetriever`), pytest + pytest-django.
+
+## Background
+
+`ChatStreamingView.post` (`src/documents/views.py`), when the request has no `document_id`
+(i.e. "chat with my whole archive" rather than "chat with this one document"), builds a
+`QuerySet` of every `Document` the requesting user is permitted to view and passes it straight
+into `stream_chat_with_documents(query_str, documents)`
+(`src/paperless_ai/chat.py`), which calls into `_stream_chat_with_documents`. Two places there
+force-materialize the entire queryset into Python objects, on **every single chat message**:
+
+1. `_document_id_filters(str(doc.pk) for doc in documents)` -- iterates every accessible
+   document just to build a `MetadataFilter(key="document_id", operator=IN,
+value=sorted(doc_ids))` for the vector-store query.
+2. `_get_document_references`'s `allowed_documents = {doc.pk: doc for doc in documents}` --
+   hydrates every accessible `Document` row into a dict, just to look up at most
+   `MAX_CHAT_REFERENCES = 3` of them later.
+
+Meanwhile the actual retrieval only ever wants `CHAT_RETRIEVER_TOP_K = 5` nodes, and shows at
+most 3 references. So the cost of _every_ chat message -- not a background job, an interactive
+request a user is staring at a spinner for -- scales with total accessible-document count, not
+with the ~5 documents that actually matter to the answer. This is worse than an equivalent
+scan in a background Celery task: a user is waiting on it in real time, on every message, and
+the cost grows as the library grows regardless of how good or bad the actual answer needs to
+be.
+
+**What this plan fixes (and what it deliberately doesn't):**
+
+1. Stop materializing full `Document` rows for the filter step -- `_document_id_filters` only
+   needs a list of ids, not hydrated rows (Task 2, Step 3).
+2. Stop permission-checking/hydrating the whole accessible set before knowing which documents
+   were even retrieved -- flip the order so retrieval happens first (bounded by
+   `CHAT_RETRIEVER_TOP_K = 5`), then permission-check only those results (Task 2, Step 4). The
+   permission check itself is unchanged in substance -- a document is only surfaced if it's in
+   the caller's permission-scoped queryset -- only its timing and the amount of data it touches
+   change.
+3. **Out of scope:** the vector-store-side `IN (...)` filter still needs the full list of
+   accessible document ids to constrain the KNN search to permitted documents -- that's
+   inherent to "chat with my whole (permitted) archive" and can't be avoided by filtering after
+   the fact (doing so would leak un-permitted document content into the LLM context). Whether
+   that `IN`-list itself is a performance problem for the vector store at very large scale is a
+   separate, unimplemented investigation and is explicitly not addressed by this plan.
+
+## Global Constraints
+
+- Backend lint/format: ruff, line length 88, double quotes, single-line isort imports (from `CLAUDE.md`).
+- Type checking: mypy + pyrefly; do not introduce new violations beyond the frozen baseline (`.mypy-baseline.txt`, `.pyrefly-baseline.json`).
+- Tests: pytest/pytest-django; match the style of the file being edited (`src/paperless_ai/tests/test_chat.py` is already idiomatic pytest with fixtures).
+- The existing permission check semantics MUST be preserved exactly: a document referenced by a retrieved node is only surfaced/cited if it is in the caller's permission-scoped `documents` queryset. No behavior change to what a user is allowed to see, only to when/how much is loaded to check it.
+- Preserve `output_language` threading through `stream_chat_with_documents` / `_stream_chat_with_documents` unchanged -- it is unrelated to this fix but must not be dropped by a careless signature rewrite.
+- Do not touch the vector-store-side `IN (...)` filter question (see Background, point 3) -- out of scope for this plan.
+
+**Suggested delegation (Claude Code `Agent` tool `subagent_type` + model tier):**
+
+- Task 0 (benchmark baseline -- open-ended: choosing a harness, interpreting numbers, deciding what "proves the bug" means): `python-pro` or `django-developer` at **Sonnet** tier. Not mechanical enough for Haiku -- it requires judgment about what to measure and whether the resulting numbers actually support the claimed scaling behavior, and it's the evidence the rest of the plan's justification rests on.
+- Task 1 (test rewrite -- mechanical: swap list literals for querysets/MagicMocks per the exact snippets already written out in this plan): `django-developer` at **Haiku** tier. The transformations are fully specified here (copy-paste-adjacent), so a fast/cheap model is sufficient; escalate to Sonnet only if the agent reports the current file has drifted from what this plan quotes.
+- Task 2 (`chat.py` rework -- the actual bug fix, changes runtime permission-check ordering): `django-developer` at **Sonnet** tier (or whatever the session's default is). This is the correctness-sensitive core of the change -- worth the stronger model even though the code is also fully specified, because a subtle mistake here (e.g. querying `documents` before `.filter(pk__in=...)` narrows it) reintroduces the exact bug being fixed.
+- Task 3 (`views.py` one-line change + locating/running the right view tests): `django-developer` at **Haiku** tier for the one-line edit; if the test-discovery grep in Step 2 turns up ambiguity, let it escalate or hand off rather than guessing.
+- Task 4 (full verification, lint/type baselines, before/after benchmark comparison): a `code-reviewer` subagent (or the `code-review` skill) at **Sonnet** tier or above for the correctness/permission-scoping review, paired with whichever agent ran Task 0 (same one, if possible, so it can compare against numbers it already understands) for the benchmark re-run in Step 0. Not a good candidate for Haiku -- both the permission-scoping check and the benchmark interpretation require judgment.
+- Use `superpowers:subagent-driven-development` to run Tasks 0-3 as independent-but-ordered subagent dispatches with review checkpoints between them, per this plan's header.

+## Current code (as of `dev` commit `fc242bb57`, for reference while implementing)
+
+Re-verify these line numbers against the live files before editing -- they will drift as other
+work lands on `dev`.
+
+`src/documents/views.py:2245-2286` (`ChatStreamingView.post`):
+
+```python
+class ChatStreamingView(GenericAPIView[Any]):
+    permission_classes = (IsAuthenticated, ViewDocumentsPermissions)
+    serializer_class = ChatStreamingSerializer
+
+    def post(self, request, *args, **kwargs):
+        request.compress_exempt = True
+        ai_config = AIConfig()
+        if not ai_config.ai_enabled:
+            return HttpResponseBadRequest("AI is required for this feature")
+
+        serializer = self.get_serializer(data=request.data)
+        serializer.is_valid(raise_exception=True)
+        question = serializer.validated_data["q"]
+
+        doc_id = serializer.validated_data.get("document_id")
+
+        if doc_id:
+            try:
+                document = Document.objects.get(id=doc_id)
+            except Document.DoesNotExist:

+            if not has_perms_owner_aware(request.user, "view_document", document):
+                return HttpResponseForbidden("Insufficient permissions")
+
+            documents = [document]
+        else:
+            documents = Document.objects.filter(
+                id__in=permitted_document_ids(request.user),
+            )
+
+        output_language = _get_llm_output_language(ai_config=ai_config, request=request)
+
+        response = StreamingHttpResponse(
+            stream_chat_with_documents(
+                query_str=question,

+            ),
+            content_type="text/event-stream",
+        )
+        return response
+```
+
+Note: the whole-library `else` branch already returns a `QuerySet` (`permitted_document_ids`
+returns a lazy `QuerySet[int]`, see `src/documents/permissions.py`) -- the bug is entirely
+inside `chat.py`, which force-materializes it. Only the single-document `if` branch needs to
+change (`[document]` -> a one-row `QuerySet`), purely so both branches share the same type.
+
+`src/paperless_ai/chat.py` (`_get_document_references`, `stream_chat_with_documents`,
+`_stream_chat_with_documents` -- abridged excerpt, elisions and inline comments below are
+annotations for this plan, not literal source; re-read the live file rather than treating this
+as a copy-paste-ready contiguous block):
+
+```python
+def _get_document_references(
+    documents: list[Document],
+    top_nodes: list,
+) -> list[dict[str, int | str]]:
+    allowed_documents = {doc.pk: doc for doc in documents}   # <-- full materialization #1
+    ...
+
+
+def stream_chat_with_documents(
+    query_str: str,
+    documents: list[Document],
+    output_language: str | None = None,
+):
+    try:
+        yield from _stream_chat_with_documents(
+            query_str,
+            documents,
+            output_language=output_language,
+        )
+    except Exception as e:
+        logger.exception("Failed to stream document chat response: %s", e)
+        yield CHAT_ERROR_MESSAGE
+
+
+def _stream_chat_with_documents(
+    query_str: str,
+    documents: list[Document],
+    output_language: str | None = None,
+):
+    if not documents:
+        yield CHAT_NO_CONTENT_MESSAGE
+        return
+    ...
+    filters = _document_id_filters(str(doc.pk) for doc in documents)  # <-- full materialization #2
+    ...
+        references = _get_document_references(documents, top_nodes)
+```
+
+All three signatures need to carry `output_language: str | None = None` through unchanged --
+this parameter is unrelated to the fix but must not be dropped.
+
+## File Structure
+
+- Modify: `src/paperless_ai/chat.py` -- change `documents` parameter type from `list[Document]` to `QuerySet[Document]` across `stream_chat_with_documents`, `_stream_chat_with_documents`, `_get_document_references`; rework `_get_document_references` to defer hydration until after retrieval.
+- Modify: `src/documents/views.py` -- `ChatStreamingView.post` builds a `QuerySet[Document]` for the single-document branch (instead of `[document]`) so both branches share the same lazy type; the whole-library branch already returns a `QuerySet` via `permitted_document_ids` and needs no structural change (just stops being force-materialized downstream).
+- Modify: `src/paperless_ai/tests/test_chat.py` -- update existing tests to pass `QuerySet[Document]` (real, via `DocumentFactory` + `django_db`, or a `QuerySet`-shaped `MagicMock` where no DB is wanted) instead of plain lists; add a regression test proving the reference lookup only queries documents actually referenced by `top_nodes`, not the whole passed queryset.
+- No change expected to `src/documents/tests/test_views.py` (search for the chat streaming view test class with `rg -n "ChatStreamingView|class.*Chat" src/documents/tests/test_views.py` before starting -- confirm the exact class name, it may have moved since this plan was drafted) -- it patches `stream_chat_with_documents` entirely and never inspects the `documents` argument's type, but Task 4 runs it to confirm.
+- Add: a benchmark script or pytest-based benchmark test (exact location decided in Task 0 Step 1) that seeds a large document library and measures query count + wall time through `_stream_chat_with_documents`, to be run before (Task 0) and after (Task 4) the fix and compared.
+
+---
+
+### Task 0: Benchmark the current (unfixed) behavior -- prove the bug's cost shape before changing code
+
+**Files:**
+
+- Add: a benchmark script/test, e.g. `src/paperless_ai/tests/test_chat_benchmark.py` (pytest-based, easiest to re-run identically in Task 4) or a one-off management-command-style script using `src/profiling.py`'s existing `profile_block` context manager (already in this repo's root, wraps `tracemalloc` + Django query counting + wall time -- see its docstring). Prefer the pytest version so Task 4 can literally re-run the same file and diff the numbers; a throwaway script is fine too if you'd rather not commit a benchmark test permanently to the suite -- ask before committing one either way, since it's not core test coverage.
+
+**Interfaces:**
+
+- Consumes: `stream_chat_with_documents`, `_get_document_references`, `_document_id_filters` as they currently exist (`list[Document]`-based, unfixed).
+- Produces: a recorded baseline (query count, wall time) at multiple library sizes, referenced again in Task 4's "after" run. This task makes no code changes to `chat.py`/`views.py` -- benchmark only.
+
+- [ ] **Step 1: Decide and set up the benchmark harness**
+
+Seed libraries at a few sizes (e.g. 10, 100, 1000 documents) via
+`DocumentFactory.create_batch(n)` (see `src/documents/tests/factories.py`), matching the
+pattern already used in this plan's own `test_get_document_references_only_queries_referenced_documents`
+test (Task 1, Step 3) which seeds 200. Wrap the call path in Django's
+`django.test.utils.CaptureQueriesContext` (or the `django_assert_num_queries` fixture for a
+fixed expected count, but here you want the _actual_ count at each size, not just an
+assertion) plus `time.perf_counter()` for wall time. `src/profiling.py`'s `profile_block`
+context manager already bundles both (query count/time + memory) if you'd rather reuse it
+than hand-roll `CaptureQueriesContext`.
+
+- [ ] **Step 2: Run the benchmark against the two hot spots described in Background**
+
+Specifically measure, at each library size:
+
+1. `_document_id_filters(str(doc.pk) for doc in documents)` (`chat.py`) -- the filter-list
+   build.
+2. `_get_document_references(documents, top_nodes)` (`chat.py`) -- the reference
+   lookup, with `top_nodes` fixed at a small constant (e.g. 1-3 nodes) regardless of library
+   size, to isolate the effect of accessible-library size on this specific function (this is
+   the function the fix changes the most).
+
+Record: query count and wall time for each, at each library size. Expect (unfixed) roughly
+linear-in-library-size query time/row-hydration cost for #2 in particular, since
+`{doc.pk: doc for doc in documents}` hydrates every row.
+
+- [ ] **Step 3: Record the baseline numbers**
+
+Write the baseline numbers into this plan file (append a small table under this task) or into
+a scratch note referenced from here -- whichever the implementer running this task prefers, as
+long as Task 4 can find and compare against it. Do not proceed to Task 1 until a baseline
+exists; the point of this task is to have something to compare the fix against, not to block
+indefinitely on a perfect benchmark harness.
+
+- [ ] **Step 4: Commit (if the benchmark harness itself is a pytest file worth keeping)**
+
+```bash
+git add src/paperless_ai/tests/test_chat_benchmark.py   # or wherever Step 1 put it
+git commit -m "Bench: baseline query count/wall time for chat document reference lookup"
+```
+
+If instead you used a throwaway script (not added to the pytest suite), skip this commit --
+just keep the recorded numbers from Step 3.
+
+---
+
+### Task 1: Rewrite chat tests to use QuerySets and add the bounded-lookup regression test (RED)
+
+**Files:**
+
+- Modify: `src/paperless_ai/tests/test_chat.py`
+
+**Interfaces:**
+
+- Consumes: `stream_chat_with_documents(query_str: str, documents, output_language: str | None = None)` (current signature, still `list[Document]` at this point -- these tests will fail until Task 2 lands).
+- Produces: nothing new for later tasks to consume; this task only changes test fixtures/assertions.
+
+- [ ] **Step 1: Replace list-based `documents` fixtures with `QuerySet`-shaped values**
+
+In `src/paperless_ai/tests/test_chat.py`, the `mock_document` fixture (around line 39-46) is a
+`MagicMock`, not a real row, so it cannot be used with a real `QuerySet.filter(pk=...)`
+lookup. Replace its use in `test_stream_chat_with_one_document_retrieval` with a
+real `DocumentFactory.create()` instance and pass `Document.objects.filter(pk=document.pk)`:
+
+```python
+from documents.models import Document
+from documents.tests.factories import DocumentFactory
+
+@pytest.mark.django_db
+def test_stream_chat_with_one_document_retrieval(patch_embed_nodes) -> None:
+    document = DocumentFactory.create(title="Test Document", content="ignored")
+    documents = Document.objects.filter(pk=document.pk)
+    with (
+        patch("paperless_ai.chat.AIClient") as mock_client_cls,
+        patch("paperless_ai.chat.load_or_build_index") as mock_load_index,

+        ) as mock_get_response_synthesizer,
+    ):
+        mock_client = MagicMock()
+        mock_client_cls.return_value = mock_client
+        mock_client.llm = MagicMock()
+
+        mock_index = MagicMock()

+                metadata={"document_id": str(document.pk), "title": "Test Document"},
+            ),
+        ]
+        mock_load_index.return_value = mock_index
+
+        mock_retriever_instance = MagicMock()
+        mock_retriever_instance.retrieve.return_value = [
+            MagicMock(
+                metadata={"document_id": str(document.pk), "title": "Test Document"},
+            ),
+        ]
+
+        mock_response_stream = MagicMock()

+                {"id": document.pk, "title": "Test Document"},
+            ],
+        )
+```
+
+Remove the `mock_document` fixture only if nothing else in the file still uses it (check with
+`rg -n "mock_document" src/paperless_ai/tests/test_chat.py` after this step).
+
+Apply the equivalent change to `test_stream_chat_with_multiple_documents_retrieval`:
+replace `doc1 = MagicMock(pk=1, ...)` / `doc2 = MagicMock(pk=2, ...)` with two
+`DocumentFactory.create(...)` instances, and pass
+`documents = Document.objects.filter(pk__in=[doc1.pk, doc2.pk])` to
+`stream_chat_with_documents`. Update the node/reference metadata to use the real created pks
+instead of hardcoded `"1"`/`"2"`.
+
+For the three non-DB tests (`test_stream_chat_empty_document_list`,
+`test_stream_chat_no_matching_nodes`,
+`test_stream_chat_unexpected_failure_returns_generic_error`), replace the list
+arguments with values that behave like an (unevaluated) `QuerySet` without touching the
+database:
+
+```python
+def test_stream_chat_empty_document_list() -> None:
+    with patch("paperless_ai.chat.load_or_build_index") as mock_load_index:
+        output = list(stream_chat_with_documents("Any info?", Document.objects.none()))
+        mock_load_index.assert_not_called()
+        assert output == ["Sorry, I couldn't find any content to answer your question."]
+```
+
+`Document.objects.none()` short-circuits Django's query execution (`QuerySet.query.is_empty()`),
+so `.exists()` on it does not hit the database and this test does not need
+`@pytest.mark.django_db`.
+
+For `test_stream_chat_no_matching_nodes` and
+`test_stream_chat_unexpected_failure_returns_generic_error`, which pass `[MagicMock(pk=1)]`
+today: these need a queryset-like object that reports non-empty and yields at least one pk,
+without a real DB row (they never reach `_get_document_references` -- one returns before
+retrieval finds nodes, the other raises during retrieval). Use a `MagicMock` configured to
+mimic the two methods actually called before that point:
+
+```python
+def _fake_documents_queryset(pks: list[int]) -> MagicMock:
+    qs = MagicMock()
+    qs.exists.return_value = bool(pks)
+    qs.values_list.return_value = pks
+    return qs
+```
+
+Add this helper near the top of the file (after `assert_chat_output`) and use
+`_fake_documents_queryset([1])` in place of `[MagicMock(pk=1)]` in both tests.
+
+Add the necessary import: `from documents.models import Document` at the top of the file.
+
+- [ ] **Step 2: Rewrite the two `TestStreamChatRetrieval` tests to pass a QuerySet**
+
+Both `test_no_nodes_yields_no_content_message` and
+`test_chat_filter_contains_only_requested_document_ids` (in class `TestStreamChatRetrieval`)
+already use real `DocumentFactory` documents and `django_db`. Change the calls:
+
+```python
+out = list(chat.stream_chat_with_documents("question?", Document.objects.filter(pk=doc.pk)))
+...
+list(chat.stream_chat_with_documents("question?", Document.objects.filter(pk=included.pk)))
+```
+
+(`doc`/`included` stay single real documents; no other change needed in these tests.)
+
+- [ ] **Step 3: Add the regression test for bounded reference lookup**
+
+Add a new test proving `_get_document_references` only touches documents that `top_nodes`
+actually reference, not every document in the passed queryset. This is the direct regression
+test for the bug described in this plan's Background section:
+
+```python
+@pytest.mark.django_db
+def test_get_document_references_only_queries_referenced_documents(
+    django_assert_num_queries,
+) -> None:
+    """Building references must not hydrate every document the caller is
+    permitted to see -- only the (<= CHAT_RETRIEVER_TOP_K) documents that
+    the retriever actually returned nodes for.
+    """
+    referenced = DocumentFactory.create(title="Referenced Document")
+    # Many more documents are "accessible" but never referenced by a node.
+    DocumentFactory.create_batch(200)
+
+    documents = Document.objects.all()
+    top_nodes = [
+        MagicMock(metadata={"document_id": str(referenced.pk), "title": "Referenced Document"}),
+    ]
+
+    # One query: `documents.filter(pk__in=candidate_ids)` for the single
+    # referenced id. No query should scale with the 200 unreferenced documents.
+    with django_assert_num_queries(1):
+        references = chat._get_document_references(documents, top_nodes)
+
+    assert references == [{"id": referenced.pk, "title": "Referenced Document"}]
+```
+
+`django_assert_num_queries` is a `pytest-django` fixture available automatically, no new
+dependency needed.
+
+- [ ] **Step 4: Run the test file and confirm it fails for the expected reason**
+
+Run: `uv run pytest --override-ini="addopts=" src/paperless_ai/tests/test_chat.py -v`
+
+Expected: multiple failures (`AttributeError`, e.g. `'list' object has no attribute 'exists'`,
+or logic mismatches), because `_stream_chat_with_documents` / `_get_document_references` still
+expect a `list[Document]`. Read the actual pytest output before proceeding -- do not assume the
+failure mode in advance.
+
+Do not proceed to Task 2 until you have read the actual failure output and confirmed the tests
+are red for a real reason (signature/behavior mismatch), not a typo in the test itself.
+
+---
+
+### Task 2: Rework `chat.py` to defer hydration and query only referenced documents (GREEN)
+
+**Files:**
+
+- Modify: `src/paperless_ai/chat.py`
+
+**Interfaces:**
+
+- Consumes: `documents: QuerySet[Document]` (passed in by `views.py`, updated in Task 3).
+- Produces: `stream_chat_with_documents(query_str: str, documents: QuerySet[Document], output_language: str | None = None)` -- same external name/params, new `documents` type. `_get_document_references(documents: QuerySet[Document], top_nodes: list) -> list[dict[str, int | str]]` -- same name/return type, new parameter type and internal behavior (queries only referenced ids).
+
+- [ ] **Step 1: Add the `QuerySet` import and update type hints**
+
+```python
+from django.db.models import QuerySet
+```
+
+(`Document` is already imported at the top of `chat.py`.) Update the signatures of
+`stream_chat_with_documents`, `_stream_chat_with_documents`, and `_get_document_references` to
+take `documents: QuerySet[Document]` instead of `documents: list[Document]`. Keep
+`output_language: str | None = None` as-is on the two functions that already carry it.
+
+- [ ] **Step 2: Replace the full-materialization emptiness check**
+
+In `_stream_chat_with_documents`:
+
+```python
+def _stream_chat_with_documents(
+    query_str: str,
+    documents: QuerySet[Document],
+    output_language: str | None = None,
+):
+    if not documents.exists():
+        yield CHAT_NO_CONTENT_MESSAGE
+        return
+```
+
+(`documents.exists()` issues a lightweight existence check; for `Document.objects.none()` it
+short-circuits without hitting the database at all.)
+
+- [ ] **Step 3: Replace the filter-building line to use ids only**
+
+```python
+    config = AIConfig()
+    filters = _document_id_filters(
+        str(pk) for pk in documents.values_list("pk", flat=True)
+    )
+```
+
+This still touches every accessible document's id (inherent to scoping the vector-store `IN`
+filter to the permitted set -- see Background, point 3, which remains out of scope), but no
+longer loads full `Document` rows -- just a flat list of integers.
+
+- [ ] **Step 4: Rework `_get_document_references` to hydrate only referenced documents**
+
+```python
+def _get_document_references(
+    documents: QuerySet[Document],
+    top_nodes: list,
+) -> list[dict[str, int | str]]:
+    candidate_ids: set[int] = set()
+    for node in top_nodes:
+        try:
+            candidate_ids.add(int(node.metadata["document_id"]))
+        except (KeyError, TypeError, ValueError):  # pragma: no cover
+            continue
+
+    if not candidate_ids:
+        return []
+
+    allowed_documents = {
+        doc.pk: doc for doc in documents.filter(pk__in=candidate_ids)
+    }
+
+    references: list[dict[str, int | str]] = []
+    seen_document_ids: set[int] = set()
+
+    for node in top_nodes:
+        try:
+            document_id = int(node.metadata["document_id"])
+        except (KeyError, TypeError, ValueError):  # pragma: no cover
+            continue
+
+        if document_id in seen_document_ids or document_id not in allowed_documents:
+            continue
+
+        seen_document_ids.add(document_id)
+        document = allowed_documents[document_id]
+        references.append(
+            _build_document_reference(document, node.metadata.get("title")),
+        )
+
+        if len(references) >= MAX_CHAT_REFERENCES:  # pragma: no cover
+            break
+
+    return references
+```
+
+`documents.filter(pk__in=candidate_ids)` re-applies the permission scoping (`documents` is
+still the caller's permission-scoped queryset) but now against at most `CHAT_RETRIEVER_TOP_K`
+(5) ids instead of the whole accessible set -- this is the permission check the original code
+performed, just run after retrieval instead of before, and bounded instead of unbounded.
+
+- [ ] **Step 5: Run the chat test file and confirm it passes**
+
+Run: `uv run pytest --override-ini="addopts=" src/paperless_ai/tests/test_chat.py -v`
+
+Expected: all tests pass, including `test_get_document_references_only_queries_referenced_documents`.
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/paperless_ai/chat.py src/paperless_ai/tests/test_chat.py
+git commit -m "Fix: bound chat document reference lookup to retrieved nodes instead of whole accessible library"
+```
+
+---
+
+### Task 3: Update `ChatStreamingView.post` to pass a QuerySet for the single-document branch
+
+**Files:**
+
+- Modify: `src/documents/views.py` (`ChatStreamingView.post` -- re-locate with `rg -n "class ChatStreamingView" src/documents/views.py` before editing, in case other changes shifted it)
+
+**Interfaces:**
+
+- Consumes: `stream_chat_with_documents(query_str, documents: QuerySet[Document], output_language)` (Task 2's new signature).
+- Produces: nothing new for later tasks.
+
+- [ ] **Step 1: Build a QuerySet in the single-document branch**
+
+Change only this one line inside `post`:
+
+```python
+            documents = Document.objects.filter(pk=document.pk)
+```
+
+in place of the current `documents = [document]`. Everything else in `post` (the
+`has_perms_owner_aware` check against the fully-hydrated `document`, the `else` branch using
+`permitted_document_ids`, the `output_language` lookup, the `StreamingHttpResponse`
+construction) is unchanged -- it already passes a `QuerySet` in the `else` branch; Task 2's
+changes inside `chat.py` are what stop that queryset from being force-materialized downstream.
+
+- [ ] **Step 2: Run the view tests**
+
+Three test locations cover this view (re-check with
+`rg -n "ChatStreamingView|/api/chat|stream_chat_with_documents" src/documents/tests/*.py` if
+more time has passed since this plan was written):
+
+1. `src/documents/tests/test_views.py`, class `TestAIChatStreamingView` -- patches
+   `stream_chat_with_documents` entirely, doesn't inspect `documents`' type.
+2. `src/documents/tests/test_api_chat.py`, class `TestChatStreamingViewInputValidation` --
+   input-validation only, doesn't reach `documents` construction.
+3. `src/documents/tests/test_permission_filtering_security.py`, class
+   `TestAiChatAllDocumentsPermissionBoundary`, test
+   `test_chat_all_documents_excludes_unshared_document` -- **this is the one that actually
+   matters for this change**: it asserts on `kwargs["documents"]` from the mocked
+   `stream_chat_with_documents` call (`{doc.pk for doc in kwargs["documents"]}`), pinning the
+   permission-scoping behavior this plan touches. Read this test specifically before/after the
+   change, not just via a blind `-k chat` filter -- iterating a `QuerySet` with a set
+   comprehension works the same as iterating a `list`, so it should keep passing unchanged, but
+   confirm rather than assume.
+
+Run:
+
+```bash
+uv run pytest --override-ini="addopts=" src/documents/tests/ -v -k chat
+uv run pytest --override-ini="addopts=" src/documents/tests/test_permission_filtering_security.py -v -k AllDocumentsPermissionBoundary
+```
+
+Expected: all pass unchanged.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add src/documents/views.py
+git commit -m "Fix: pass single-document chat queries as a QuerySet instead of a materialized list"
+```
+
+---
+
+### Task 4: Full verification
+
+**Files:** none (verification only, except Step 0's benchmark re-run reuses Task 0's file)
+
+- [ ] **Step 0: Re-run Task 0's benchmark against the fixed code and compare**
+
+Re-run the exact same benchmark harness from Task 0 (same library sizes, same measured
+functions) now that Task 2's fix has landed. This is the actual proof the fix works, not just
+that tests pass -- prove the improvement, don't assume it. Expect:
+
+- `_get_document_references` query count/time to become roughly constant (bounded by
+  `CHAT_RETRIEVER_TOP_K = 5`) instead of scaling with library size.
+- `_document_id_filters`' cost is unchanged in shape (Task 2 only avoids hydrating full
+  `Document` rows there, via `.values_list("pk", flat=True)`; it still touches every accessible
+  id -- see Background, point 3, still out of scope) but should show reduced wall time/memory
+  from not loading full rows.
+
+Record the before/after comparison (e.g. as a small table: library size, before query
+count/time, after query count/time) back into Task 0's section of this plan. If the numbers do
+NOT show the expected improvement, stop and treat that as a signal the fix is incomplete or
+wrong before proceeding to the rest of this task's steps.
+
+- [ ] **Step 1: Run the full `paperless_ai` and relevant `documents` test suites**
+
+```bash
+uv run pytest --override-ini="addopts=" src/paperless_ai/tests/ -v
+uv run pytest --override-ini="addopts=" src/documents/tests/ -v -k chat
+```
+
+Expected: all pass.
+
+- [ ] **Step 2: Run ruff, and mypy/pyrefly via prek, to confirm no new baseline violations or lint issues**
+
+```bash
+uv run ruff check src/paperless_ai/chat.py src/documents/views.py
+uv run ruff format --check src/paperless_ai/chat.py src/documents/views.py
+uv run prek run --all-files
+```
+
+Expected: clean, and no new violations beyond `.mypy-baseline.txt` / `.pyrefly-baseline.json`.
+
+- [ ] **Step 3: Confirm both in-scope fixes from Background are addressed**
+
+Point 1 (don't materialize full `Document` rows for the filter step) -- addressed by Task 2 Step 3.
+Point 2 (permission-check only `top_nodes`, bounded by `CHAT_RETRIEVER_TOP_K`) -- addressed by Task 2 Step 4.
+Point 3 (whether the vector-store `IN (...)` filter itself is a KNN scaling concern) remains
+explicitly out of scope for this plan -- if it needs tracking as future work, open a fresh
+issue/note for it rather than reviving old diagnosis documents.
+
+---
+
+## Self-Review Notes
+
+- **Spec coverage:** both in-scope points from Background ("don't materialize full `Document` rows for the filter step" and "permission-check only `top_nodes`, bounded by `CHAT_RETRIEVER_TOP_K`") are implemented in Task 2. The vector-store `IN` filter scaling question is explicitly out of scope and not silently dropped -- it's called out in Background, Global Constraints, and Task 4 Step 3.
+- **Placeholder scan:** no TBD/TODO markers; every step has literal code.
+- **Type consistency:** `documents: QuerySet[Document]` is consistent across `stream_chat_with_documents`, `_stream_chat_with_documents`, `_get_document_references`, and both call sites in `views.py`. `_build_document_reference`'s signature is unchanged (still takes a hydrated `Document`). `output_language` threading is preserved unchanged throughout.
+- **Self-contained:** this plan does not depend on any other document, branch, or worktree existing -- all context needed to execute it (bug diagnosis, current code, fix design) is inlined above.
