a69e0c73c7 feat(rss): support deleted-file sync (#14493)
### What problem does this PR solve?

Partially addresses #14362.

This PR enables syncing deleted files for RSS data sources.

Previously, RSS incremental sync only returned feed entries whose
timestamps were inside the poll window. If an entry was removed from the
RSS feed, RAGFlow had no full current RSS snapshot to pass into the
shared stale-document cleanup path, so the deleted remote entry could
remain in the knowledge base.

This PR:
- adds `retrieve_all_slim_docs_perm_sync()` to `RSSConnector`
- reuses the same `rss:<md5(stable_key)>` document ID derivation used by
normal RSS ingest
- returns `(document_generator, file_list)` for incremental RSS sync
when `sync_deleted_files` is enabled
- captures the poll end timestamp before snapshot/poll so cleanup does
not race against the same sync window
- adds start/end logs around RSS slim snapshot collection
- exposes the deleted-file sync toggle for RSS in the data source UI

Per maintainer request on related datasource PRs, this PR contains no
test-case changes. Local verification was run with an external script.

bedf9592ef feat(webdav): support deleted-file sync via slim snapshot (#14491)
## What problem does this PR solve?

Incremental WebDAV sync only ingested files whose modification time fell
inside the poll window; documents removed on the WebDAV server were
never removed from the knowledge base. This aligns with
[#14362](https://github.com/infiniflow/ragflow/issues/14362)
(coordinated datasource “sync deleted files” work).

This PR adds a **full-tree slim snapshot**
(`retrieve_all_slim_docs_perm_sync`) that enumerates current remote
paths **without downloading file contents**, using the same logical
document IDs as full ingest (`webdav:{base_url}:{file_path}`). When
**`sync_deleted_files`** is enabled on incremental runs, sync returns
**`(document_generator, file_list)`** so **`SyncBase`** runs
**`cleanup_stale_documents_for_task`** and removes KB rows no longer
present remotely.

Design notes:

- **`_list_files_recursive`** gains **`filter_by_mtime`**: snapshot
passes **`filter_by_mtime=False`** (full tree under **`remote_path`**);
**`poll_source`** keeps mtime-window filtering as before.
- Slim snapshot applies the same **extension** and **`size_threshold`**
rules as **`_yield_webdav_documents`** so retain IDs match what would be
indexed.
- **`end_ts`** is captured before building **`file_list`**, then
**`poll_source`** uses the same upper bound (consistent with
Dropbox-style connectors).

17eda04b8d feat(zendesk): support deleted-file sync (#14487)
### What problem does this PR solve?

Refs #14362.

This PR enables syncing deleted files for Zendesk data sources.

Previously, Zendesk incremental sync never returned a slim remote
snapshot to the shared stale-document cleanup path, so deleted remote
Zendesk records could remain in RAGFlow. The existing Zendesk slim
snapshot also included records that ingestion intentionally skips, such
as draft articles, articles without bodies, skipped-label articles,
empty-body articles, and tickets with `status == "deleted"`.

This PR:
- exposes the deleted-file sync option for Zendesk in the data source UI
- returns Zendesk slim snapshots during incremental sync when
`sync_deleted_files` is enabled
- reuses Zendesk indexability rules so cleanup compares against the same
records ingestion can materialize
- adds start/end logs around Zendesk slim snapshot collection for
operational visibility

Per maintainer request, this PR contains no test-case changes. Manual
verification recording will be provided separately.

8f75e52bbf feat(asana): support deleted-file sync (#14468)
### What problem does this PR solve?

Partially addresses #14362.

Adds deleted-file sync support for the Asana data source. Asana already
indexes task attachments as documents, but it did not provide the slim
document snapshot required by stale-document reconciliation, and the
sync wrapper never returned a `file_list` for cleanup.

This PR:
- adds `retrieve_all_slim_docs_perm_sync()` to `AsanaConnector`
- builds slim IDs with the same `asana:{task_id}:{attachment_gid}`
format used by indexed documents
- avoids downloading attachment blobs during the snapshot
- aborts the snapshot if Asana API errors occur, preventing partial
snapshots from deleting valid local docs
- captures the incremental poll end time before snapshotting and makes
`poll_source()` respect that boundary
- exposes the deleted-file sync toggle for Asana in the data source UI

Per maintainer request, this PR contains no test-case changes. Manual
verification recording will be provided separately.

e992fe39b2 fix: the oceanbase database connector constructs sql... in ob_conn.py (#14470)
## Summary
Fix critical severity security issue in `rag/utils/ob_conn.py`.

## Vulnerability
| Field | Value |
|-------|-------|
| **ID** | V-003 |
| **Severity** | CRITICAL |
| **Scanner** | multi_agent_ai |
| **Rule** | `V-003` |
| **File** | `rag/utils/ob_conn.py:691` |

**Description**: The OceanBase database connector constructs SQL WHERE
clauses by directly embedding user-controlled filter expressions using
Python f-strings at lines 726, 777, 781, 787, 793, 821, and 827. No
parameterization or allowlist validation is applied before the
expressions are incorporated into live SQL queries. This is the most
critical vulnerability in the codebase because it directly exposes the
RAG knowledge base — the platform's core business asset — to complete
compromise.

## Changes
- `rag/utils/ob_conn.py`

## Verification
- [x] Build passes
- [x] Scanner re-scan confirms fix
- [x] LLM code review passed

2932b65da6 feat(seafile): support deleted-file sync via slim snapshot (#14499)
### What problem does this PR solve?

Incremental Seafile sync only ingests files whose modification time
falls in the poll window; documents removed in Seafile were never
removed from the knowledge base. This contributes to
[#14362](https://github.com/infiniflow/ragflow/issues/14362) (datasource
“sync deleted files” coordination).

This PR adds a **slim snapshot** (`retrieve_all_slim_docs_perm_sync`)
that enumerates current remote file IDs **without downloading content**,
using the same logical IDs as full ingest
(`seafile:{repo_id}:{file_id}`). When **`sync_deleted_files`** is
enabled on incremental runs, **`SeaFile._generate`** returns
**`(document_generator, file_list)`** so **`SyncBase`** can run
**`cleanup_stale_documents_for_task`** and remove stale KB documents.

### Type of change

- [x] New Feature (non-breaking change which adds functionality)
### What changed

- **`common/data_source/seafile_connector.py`**: `SeaFileConnector`
implements **`SlimConnectorWithPermSync`**;
**`_list_files_recursive(..., filter_by_mtime=...)`** supports full-tree
listing for snapshots; **`retrieve_all_slim_docs_perm_sync()`** reuses
the same library/root scan as ingest and applies the same **size**
ceiling; logging for snapshot start/end and counts.
- **`rag/svr/sync_data_source.py`**: **`SeaFile._generate`** validates
**`batch_size`**, captures **`end_ts`** before snapshot +
**`poll_source`**, wraps slim retrieval in **`try`/`except`** (
**`file_list = None`** on failure so ingest continues), returns
**`(generator, file_list)`**.

811e9826d0 perf: avoid O(n²) array growth in embedding accumulation (#14369)
### What problem does this PR solve?

Both tokenizer (`rag/flow/tokenizer/tokenizer.py`) and
`BuiltinEmbed.encode`
(`rag/llm/embedding_model.py`) currently accumulate embedding batches
via
`np.concatenate` inside the per-batch loop. `np.concatenate` allocates a
new
array and copies all existing data on every call, so accumulating N
batches
is O(N²) in both time and peak memory.

Replacing the incremental concatenate with a list-of-batches + a single
`np.vstack` at the end gives O(N) total work.

For tokenizer the title-vector broadcast `np.concatenate([vts[0]] * N)`
is
also replaced by `np.tile`, which does the same job with a single
contiguous
allocation instead of building a Python list of references.

This is purely a CPU/memory optimisation — output shape and dtype are
unchanged. Measured impact grows with document size:
  -   1k chunks (batch 512, 2 iters):    ~negligible
  -  10k chunks (20 iters):              ~10× speedup on this stage
  - 100k chunks (195 iters):             ~100× speedup, and peak RAM
drops from O(N) extra to near-zero

2bc8c6d35e feat(dropbox): support deleted-file sync (#14476)
### What problem does this PR solve?

Partially addresses #14362 by adding deleted-file sync support for the
Dropbox data source.

Dropbox previously did not provide the slim current-file snapshot
required by stale document reconciliation, and its sync runner returned
only document batches. As a result, enabling deleted-file sync could not
remove local documents that had been deleted from Dropbox.

This PR:
- Adds `retrieve_all_slim_docs_perm_sync()` to `DropboxConnector`.
- Reuses Dropbox metadata traversal to collect current remote file IDs
without downloading file contents.
- Wires incremental Dropbox sync to return `(document_generator,
file_list)` when `sync_deleted_files` is enabled.
- Enables the deleted-file sync toggle for Dropbox in the data source
settings UI.
- Adds regression coverage for slim snapshots, nested folders, paginated
listings, duplicate filenames, and full reindex behavior.

Tests:
- `uv run pytest test/unit_test/common/test_dropbox_connector.py -q`
- `uv run pytest test/unit_test/rag/test_sync_data_source.py -q`
- `uv run pytest test/unit_test/common/test_dropbox_connector.py

74fa54f122 feat(google-drive): optimize memory payload and enable sync deletion (#14372)
**Addresses the Google Drive integration for #14362**

This PR completely overhauls the Google Drive sync logic to accurately
detect remote deletions, while drastically reducing the memory footprint
during the snapshot phase.

### What changed under the hood:

* **Killed the memory bloat:** Swapped out the massive document
dictionary objects for a lightweight `collections.namedtuple` (`SlimDoc
= namedtuple('SlimDoc', ['id'])`). This prevents RAM spikes during
`retrieve_all_slim_docs_perm_sync` on massive enterprise drives.
* **Flawless downstream integration:** The `SlimDoc` object relies on
simple duck typing. It perfectly delivers the `.id` attribute required
by `ConnectorService.cleanup_stale_documents_for_task`, meaning your
core `hash128` vector cleanup logic runs natively without modification.
* **Fixed the Shared Drive blindspot:** The standard API query was
missing team folders. Injected the `corpora="allDrives"` and
`includeItemsFromAllDrives=True` override flags so the connector now
accurately maps state across both personal workspaces and organizational
Shared Drives.

### Testing:
Isolated the Google API retrieval logic locally to prove the `SlimDoc`
mapping works and correctly registers state drops when a file is trashed
remotely.

2846a93998 Fix: Remove hardcoded page limits causing parsing failures on large PDFs (>300 pages) (#14382)
### What problem does this PR solve?

Fixes #14196

## Problem

When using DeepDOC to parse large PDFs (over 1000 pages), the parser
silently truncated processing at 300 pages due to a hardcoded default
`page_to=299` in `RAGFlowPdfParser.__images__()`. This caused:

- **Errors** on pages beyond the limit
- **Poor image quality** as the parser attempted to compensate with
missing page data
- **Inconsistent chunk splitting** between full PDF imports and partial
imports

Additionally, the codebase scattered magic numbers (`299`, `600`,
`10000`, `100000`, `100000000`, `10000000000`, `10**9`) across 22 files
as sentinel values for "parse all pages", making future maintenance
error-prone.

## Root Cause

```python
# deepdoc/parser/pdf_parser.py (before)
def __images__(self, fnm, zoomin=3, page_from=0, page_to=299, callback=None):
    # Only the first 300 pages were rendered; everything beyond was silently dropped
```

While most callers in `rag/app/*.py` correctly passed `to_page=100000`,
the base class `RAGFlowPdfParser.__call__()` and `parse_into_bboxes()`
invoked `__images__` **without** forwarding `page_from`/`page_to`,
falling back to the restrictive default of 299.

## Solution

### 1. Define constants in `common/constants.py`

```python
MAXIMUM_PAGE_NUMBER = 100000                        # Used by the parsing layer
MAXIMUM_TASK_PAGE_NUMBER = MAXIMUM_PAGE_NUMBER * 1000  # Used by the task/DB layer
```

### 2. Replace all hardcoded sentinel values

| Layer | Files Changed | Old Values | New Value |
|---|---|---|---|
| **Deepdoc parsers** | `pdf_parser.py`, `mineru_parser.py`,
`docling_parser.py`, `opendataloader_parser.py`, `paddleocr_parser.py`,
`docx_parser.py` | `299`, `600`, `10**9`, `100000000` |
`MAXIMUM_PAGE_NUMBER` |
| **Chunk parsers** | `naive.py`, `book.py`, `qa.py`, `one.py`,
`manual.py`, `paper.py`, `presentation.py`, `laws.py`, `resume.py`,
`email.py`, `table.py` | `100000`, `10000`, `10000000000` |
`MAXIMUM_PAGE_NUMBER` |
| **Task/DB layer** | `db_models.py`, `task_service.py`,
`document_service.py`, `file_service.py` | `100000000` |
`MAXIMUM_TASK_PAGE_NUMBER` |

### 3. Fix `parse_into_bboxes()` missing parameters

Added `from_page`/`to_page` parameters to `parse_into_bboxes()` so that
the `rag/flow/parser/parser.py` DeepDOC path no longer falls back to the
restrictive default.

0d87cecae2 feat: persist PDF bookmark outline as document metadata (#13287)
## Summary

PDF files often contain a bookmark/outline tree (table of contents built
into the file by the authoring tool). RAGFlow's `pdf_parser.outlines`
already extracts these `(title, depth)` tuples via pypdf, but they are
used ephemerally during chunking (`manual` parser uses them for
hierarchy detection) and then discarded.

This PR persists the outline as `doc.meta_fields["outline"]` — a JSON
array of `{"title": str, "depth": int}` objects — so downstream features
can use the structural information.

### Why this matters

- **Complementary to `toc_extraction`** — the existing `toc_extraction`
feature uses LLM calls to generate a TOC and only works for the `naive`
parser. The raw PDF outline is free (already extracted by pypdf), works
for all parsers, and captures the author's original document structure.
- **Document navigation** — frontends can render a clickable TOC from
the outline
- **Entity extraction** — the outline provides a structural map for
identifying document sections and key topics
- **Search result context** — knowing which section a chunk belongs to
helps users evaluate relevance

### Changes

| File | Change | LOC |
|------|--------|-----|
| `rag/app/naive.py` | Attach `pdf_parser.outlines` as `__outline__` on
first chunk dict | ~7 |
| `rag/app/manual.py` | Same for the manual parser | ~5 |
| `rag/svr/task_executor.py` | Extract `__outline__`, persist via
`DocMetadataService.update_document_metadata()` | ~12 |

### Design decisions

- **Transient key pattern**: The outline is passed from parser →
task_executor via `__outline__` on the first chunk dict, then removed
before indexing. This follows the same pattern as `metadata_obj` for
LLM-generated metadata.
- **No schema changes**: Uses the existing `meta_fields` JSON column on
the document table.
- **Graceful degradation**: If a PDF has no outline (common for scanned
docs), nothing is stored. If persistence fails, it logs a warning and
continues — parsing is not interrupted.

### Backward compatibility

- **Fully backward compatible** — no existing fields, behavior, or
schemas changed
- PDFs without outlines are unaffected
- Existing `meta_fields` data is preserved (merged, not overwritten)

## Test plan

- [ ] Parse a PDF with bookmarks (e.g. any multi-chapter document),
verify `meta_fields["outline"]` is populated
- [ ] Parse a PDF without bookmarks, verify no errors and no outline key
in meta_fields
- [ ] Verify existing `meta_fields` data is preserved (not overwritten)
when outline is added
- [ ] Verify `manual` parser also persists outlines
- [ ] Verify outline JSON structure: `[{"title": "Chapter 1", "depth":
0}, ...]`

f3b7d55a1e fix: handle Infinity table-not-exist error (3022) in update() methods (#14153)
### What problem does this PR solve?

## Summary

Closes #6102

When using Infinity as the document store engine (GPU version), calling
`update()` on a non-existent table throws an unhandled
`InfinityException` with error code 3022 (`TABLE_NOT_EXIST`). This
causes users to see a raw "3022" error when clicking on a parsed
document.

## Root Cause

The `update()` methods in both `rag/utils/infinity_conn.py` and
`memory/utils/infinity_conn.py` call `db_instance.get_table(table_name)`
without catching `InfinityException`. In contrast, other CRUD methods
(`insert`, `delete`, `search`) all handle this exception gracefully:

| Method   | Handles table-not-exist? | Behavior |
|----------|--------------------------|----------|
| `insert`  |  Yes | Auto-creates the table |
| `search`  |  Yes | Skips the table |
| `delete`  |  Yes | Returns 0 |
| `update`  |  **No** | Crashes with 3022 |

Additionally, `api/apps/document_app.py` worked around this with a
fragile string match (`"3022" in msg`) to detect the error.

## Changes

- **`rag/utils/infinity_conn.py`**: Catch `InfinityException` in
`update()`. When `TABLE_NOT_EXIST` is detected, log a warning and return
`False` — consistent with `delete()`.
- **`memory/utils/infinity_conn.py`**: Apply the same fix to its
`update()` method.
- **`api/apps/document_app.py`**: Remove the fragile `"3022"`
string-matching workaround. Table-not-exist is now handled by the `if
not ok` path with an improved error message.

3ad3241ae0 feat: persist RAPTOR layer metadata on summary chunks (#13286)
## Summary

RAPTOR's recursive clustering builds a `layers` list tracking
`(start_idx, end_idx)` boundaries per level, but currently discards this
information — only the flat `chunks` list is returned. This makes it
impossible to distinguish leaf-level summaries from top-level ones.

This PR:
- Returns `(chunks, layers)` tuple from `raptor.py`'s `__call__`
- Annotates each RAPTOR summary chunk with `raptor_layer_int` (1 = first
summary level, 2 = summary-of-summaries, etc.)
- Adds `raptor_layer_int` to `infinity_mapping.json` (Elasticsearch
handles it via existing `*_int` dynamic template)

### Why this matters

Downstream features need to know which RAPTOR layer a summary belongs
to:
- **Retrieving the top-level document summary** for entity extraction,
search snippets, or document comparison
- **Filtering by abstraction level** — users may want only high-level
summaries or only leaf-level cluster summaries
- **RAPTOR recall quality** — #10951 reports summaries not being
recalled for definition queries; layer metadata enables targeted
retrieval

### Changes

| File | Change | LOC |
|------|--------|-----|
| `rag/raptor.py` | Return `(chunks, layers)` tuple | ~3 |
| `rag/svr/task_executor.py` | Build `chunk_layer` mapping, set
`raptor_layer_int` | ~12 |
| `conf/infinity_mapping.json` | Add `raptor_layer_int` integer field |
~1 |

### Backward compatibility

- **Additive only** — no existing fields or behavior changed
- Existing RAPTOR chunks continue to work (they'll have
`raptor_layer_int = 0` by default)
- New RAPTOR chunks get layer metadata automatically

## Test plan

- [ ] Parse a document with RAPTOR enabled, verify `raptor_layer_int` is
set on indexed chunks
- [ ] Verify `raptor_layer_int` values increase with abstraction level
(layer 1 < layer 2 < ...)
- [ ] Verify existing RAPTOR deletion (`delete by raptor_kwd`) still
works
- [ ] Verify Infinity backend accepts the new field

78188ce9e9 Feat: add OpenDataLoader PDF parser backend (#14058) (#14097)
### What problem does this PR solve?

Closes #14058.

RAGFlow supports multiple PDF parsing backends (DeepDOC, MinerU,
Docling, TCADP, PaddleOCR). This PR adds **OpenDataLoader**
([opendataloader-project/opendataloader-pdf](https://github.com/opendataloader-project/opendataloader-pdf))
as a new optional backend, giving users a deterministic, local-first
alternative with competitive table extraction accuracy.

### Type of change

- [x] New Feature (non-breaking change which adds functionality)
- [x] Documentation Update

---

### Changes

#### Backend
- `deepdoc/parser/opendataloader_parser.py` — new `OpenDataLoaderParser`
class inheriting `RAGFlowPdfParser`. Implements `check_installation()`
(guards Python package + Java 11+ runtime), `parse_pdf()` with
JSON-first extraction (heading/paragraph/table/list/image/formula) and
Markdown fallback, position-tag generation compatible with the shared
`@@page\tx0\tx1\ty0\ty1##` format, and temp-dir lifecycle with cleanup.
- `rag/app/naive.py` — new `by_opendataloader()` wrapper, registered in
`PARSERS` dict, added to `chunk_token_num=0` override list.
- `rag/flow/parser/parser.py` — `"opendataloader"` branch in the
pipeline PDF handler + check validation list.

#### Infrastructure
- `docker/entrypoint.sh` — `ensure_opendataloader()` function: opt-in
via `USE_OPENDATALOADER=true`, skips gracefully if Java is not on PATH.

#### Frontend
- `web/src/components/layout-recognize-form-field.tsx` —
`OpenDataLoader` added to `ParseDocumentType` enum and parser dropdown.
Cascades automatically to the pipeline editor's Parser component.

#### Docs
- `docs/guides/dataset/select_pdf_parser.md` — added OpenDataLoader
entry and full env-var reference.

### Environment variables

| Variable | Default | Description |
|---|---|---|
| `USE_OPENDATALOADER` | `false` | Set `true` to install
`opendataloader-pdf` on container startup |
| `OPENDATALOADER_VERSION` | latest | Pin the PyPI release (e.g.
`==2.2.1`) |
| `OPENDATALOADER_HYBRID` | _(unset)_ | Enable hybrid AI mode (e.g.
`docling-fast`) |
| `OPENDATALOADER_IMAGE_OUTPUT` | _(unset)_ | `off` / `embedded` /
`external` |
| `OPENDATALOADER_OUTPUT_DIR` | _(tmp)_ | Persistent output dir; temp
dir used + cleaned if unset |
| `OPENDATALOADER_DELETE_OUTPUT` | `1` | `0` to retain intermediate
files for debugging |
| `OPENDATALOADER_SANITIZE` | _(unset)_ | `1` to filter prompt-injection
patterns from output |

---

### Dependencies

- **Runtime**: `opendataloader-pdf` (PyPI, Apache 2.0) — opt-in, not
added to `pyproject.toml` core deps. Installed by
`ensure_opendataloader()` at container startup when
`USE_OPENDATALOADER=true`.
- **System**: Java 11+ on PATH (JVM is the underlying engine). The
installer skips with a warning if `java` is not found.

---

### How to test

**Standalone parser:**
```bash
source .venv/bin/activate
uv pip install opendataloader-pdf
python3 -c "
import sys; sys.path.insert(0, '.')
from deepdoc.parser.opendataloader_parser import OpenDataLoaderParser
p = OpenDataLoaderParser()
print('available:', p.check_installation())
s, t = p.parse_pdf('path/to/test.pdf', parse_method='pipeline')
print(f'sections={len(s)} tables={len(t)}')
"

```

d84438fd53 fix azure blob put method param (#14329)
### What problem does this PR solve?

when use azure blob as the file container, when click parse file, it
calls:

```python
partial(settings.STORAGE_IMPL.put, tenant_id=task["tenant_id"])
```
So any storage backend used there must accept tenant_id as a kwarg. 
RAGFlowAzureSasBlob.put() did not, causing:
```
TypeError: ... got an unexpected keyword argument 'tenant_id'
```
Now it does, so parsing should proceed past this point.

38e45a1117 Fix: serialize GraphRAG entity resolution merges to avoid graph mutation races (#14237)
### What problem does this PR solve?

This PR fixes the merge-phase crash reported in #14236 during GraphRAG
entity resolution.

The issue happens after candidate pair resolution completes, when
multiple merge coroutines mutate the same shared `networkx` graph
concurrently. In `_merge_graph_nodes`, the code iterates over
`graph.neighbors(node1)` and also awaits during edge/description
merging. That allows another coroutine to modify the graph adjacency
structure in between, which can trigger `RuntimeError: dictionary keys
changed during iteration` and can also lead to unsafe shared-graph
mutation.

This change keeps the PR scoped to that single issue by:
- serializing merge-time graph mutations with a dedicated merge lock
- snapshotting `graph.neighbors(node1)` with `list(...)` before
iteration

Together, these changes prevent concurrent mutation of the shared graph
during the merge phase and make the merge loop safe against live-view
invalidation.

Fixes #14236

### Implementation Notes
- Uses the `openai/` LiteLLM prefix — consistent with other
OpenAI-compatible aggregation platforms (SILICONFLOW, DeerAPI, CometAPI,
OpenRouter, n1n, Avian, etc.)
- `Astraflow` (global, rank 250) and `Astraflow-CN` (China, rank 249)
are separate factory entries, allowing users to choose the optimal
endpoint based on their region.
- All model classes cleanly subclass existing base classes (`Base`,
`OpenAIEmbed`, `OpenAI_APIRerank`, `GptV4`, `OpenAITTS`, `GPTSeq2txt`)
with no custom logic needed — the provider is fully OpenAI-compatible.

22c6648348 Fix: forwarding highlight param (#14112)
Closes #9078

### What problem does this PR solve?

The `retrieval_test` endpoint in `chunk_app.py` never forwarded the
`highlight` request parameter to `retriever.retrieval()`, so the search
engine never produced highlight snippets. Additionally, the frontend
always rendered `content_with_weight` instead of preferring the
`highlight` field, and the CSS rule color `var(--accent-primary)` didn't
work because the variable stores an RGB triplet `(45,212,191)` requiring
the `rgb()` wrapper.

### Before

- Search page: displayed raw content_with_weight as a wall of plain
white text with no term highlighting, including markdown headings
rendered as literal text
- Retrieval testing page: showed `content_with_weight` in a plain `<p>`
tag, no `<em>` tags rendered, no highlight coloring
- Children chunks: when child chunks were consolidated into a parent via
`retrieval_by_children`, any highlight data from children was discarded
- TOC chunks: chunks fetched via `retrieval_by_toc` had no `highlight`
field, appearing as plain text while other chunks had highlights

**Retrieval testing**:

alt="before-retrieval-no-highlight-cropped"
src="https://github.com/user-attachments/assets/5c6f5a5e-6c11-461a-bdb4-049d7dfb7a33"

**Search**:

src="https://github.com/user-attachments/assets/be7b5152-72ef-40da-a8fd-921e997ae7d3"
/>

### After

- Search page: displays the highlight field with search terms rendered
in teal/cyan color (`rgb(var(--accent-primary))`)
- Retrieval testing page: sends highlight: true in the request, uses
`HighLightMarkdown` component to render `<em>` tags with proper coloring
- Children chunks: highlights from child chunks are joined and preserved
on the parent
- TOC chunks: when other chunks have highlights, TOC-fetched chunks use
`content_with_weight` as a highlight fallback

1. **Hardcoded pool size** — `infinity_conn_pool.py` hardcoded
`ConnectionPool(max_size=4)` on initial creation and `max_size=32` on
refresh. Operators cannot tune this without patching code.
2. **No retry on transient failures** — a single `TOO_MANY_CONNECTIONS`
on edge deletes or chunk inserts kills the entire resolution+community
pipeline with no retry.

### Changes

#### `common/doc_store/infinity_conn_pool.py`

- Read `ConnectionPool` `max_size` from the `INFINITY_POOL_MAX_SIZE`
environment variable (default: `4`), applied consistently to both
initial creation and refresh paths.
- Log the actual pool size on startup for easier debugging.

#### `rag/graphrag/utils.py` — `set_graph()`

- **Edge deletes**: add exponential-backoff retry (3 attempts, 1s/2s/4s
delays) so transient `TOO_MANY_CONNECTIONS` errors are retried instead
of failing the entire job. Concurrency continues to be gated by the
existing `chat_limiter`.
- **Batch inserts**: add exponential-backoff retry (3 attempts, 1s/2s/4s
delays) for the same reason.


### Type of change

- [x] Bug Fix (non-breaking change which fixes an issue)
