fix(ingestion): improve Extractor/LLM robustness and Python->Go parity (#17470)
## Summary
This PR hardens the Go ingestion **Extractor** and **LLM retry** paths
and closes several Python->Go parity gaps in the keyword/question/tag
extraction flow.
- **Generic retry utility** (`internal/common/retry.go`):
`RetryWithBackoff` with exponential backoff (default 3 retries, 2s
initial delay, capped at 1m), context-aware sleep, and a `maxRetries<=0`
fast path. Covered by `internal/common/retry_test.go`.
- **LLM retry reuse**: `agent/component/llm_retry.go` now delegates to
`common.RetryWithBackoff` instead of an inline loop (behavior preserved:
ctx cancellation short-circuits the backoff).
- **Extractor LLM calls** (`extractor.go`):
- `call()` now retries transient LLM failures via `RetryWithBackoff`
(retry exhaustion fails the chunk instead of silently skipping).
- Sets `temperature = 0.2`, matching Python `generator.py:230,245`.
- Runs keyword and question extraction **concurrently** per chunk when
both are enabled (`task_executor.py:444-448`), with mutex-guarded map
writes to avoid data races.
- Substitutes `{field_name}` placeholders (including `{chunks}` -> chunk
text) in `prompt`/`system_prompt` before the call, mirroring Python
`string_format` (`extractor.py:102-103`); unmatched placeholders are
left as-is.
- Falls back to the **tenant default chat model** when `llm_id` is empty
(`task_executor.py:573-574`).
- Strips `` **greedily** (`strings.LastIndex`) in
`cleanExtractionResult`.
- **Auto-tagging** (`extractor_tag.go`): drops the `in.llmID != ""`
guards so an empty `llm_id` no longer skips tagging (uses the tenant
default model), and strips `` greedily in `parseTaggerResponse`.
- **Docs**: fixes a misleading `PresentationChunker` docstring that
claimed per-slide `image`/`position` output (the PPTX path emits none —
unlike PDF), and removes a stale `docs/migration_python_go_diff.md`
reference in `media_dispatch.go`.
## Test plan
- `bash build.sh --test ./internal/common/...` — passes (new retry
utility + tests).
- `bash build.sh --test ./internal/ingestion/component/...` — passes
(extractor/chunker/schema).
- `gofmt` and lefthook pre-commit checks pass.
Note: the personal `docs/migration_python_go_diff.md` working notebook
in the tree is intentionally **not** part of this PR.

Fix(go): align ingestion pipeline with Python (parser/media dispatch + PDF coordinate chain + Chunker) (#17349)
## Summary Aligns the Go ingestion pipeline with the Python implementation, closing several behavioral gaps found during the Python→Go migration (tracked in `docs/migration_python_go_diff.md`). Covers parser/media dispatch alignment, the PDF coordinate-chain (preview images, outline→title, chunk coordinate finalization), and the Chunker Token/QA batches below. Commits are grouped as follows. ### 1. Fix parser params ( |

fix(ingestion): align laws DSL with Python — heading fallback, colon-title, short-line filter, remove_toc, and image extension mapping (#17200)
## Summary
This PR aligns the Go ingestion pipeline's **Laws** DSL template with
the Python implementation by fixing heading-detection gaps, adds
image-extension support, refactors the **Extractor** component's LLM
resolution, hardens heading detection for CJK text, and makes the
Extractor accept the Python DSL prompt key names
(`sys_prompt`/`prompts`) alongside the Go names.
## Changes
### 1. Picture file-type detection (`internal/utility/file.go`)
Adds explicit mapping for common image extensions (png, jpg, jpeg, gif,
bmp, tiff, tif, webp, svg, ico, avif, heic, apng) → `FileTypeVISUAL`,
with regression tests.
### 2. Laws DSL heading-detection alignment
(`internal/ingestion/component/chunker/`)
Four fixes to `resolveTitleLevels`:
| Fix | What changed | Why |
|-----|-------------|-----|
| **DOCX `ck_type` fallback** | `ckType` field on `lineRecord`,
propagated from `ChunkDoc.CKType` in `recordsFromStructured`. When
`ck_type=="heading"`, assign `fallbackLevel`. | office_oxide extracts
DOCX heading metadata, but the info was lost before reaching the heading
detector. Word headings whose text doesn't match any regex (e.g.
"Introduction") were treated as body. |
| **`make_colon_as_title` promotion** | `isColonTitle()`: promotes lines
ending with `:`/`：` that have sentence-ending punctuation before the
colon and ≥32 runes between them. | Mirrors Python's
`make_colon_as_title` in `rag/nlp/__init__.py`. Triple guard prevents
false positives. |
| **Short/numeric line filter** | Lines with ≤1 rune or purely numeric
are pinned to body level. | Mirrors Python `tree_merge`'s filter of
`sections` where `len(...) <= 1` or `re.match(r"[0-9]+$", ...)`. |
| **PDF `remove_toc`** | `"remove_toc": true` added to the PDF parser
setup in `ingestion_pipeline_laws.json`. | The Go PDF parser already
supports TOC removal; the Book template already enables it. |
### 3. Extractor llm_id resolution
(`internal/ingestion/component/extractor.go`)
Refactored to handle both **bare tenant_model UUIDs** and **composite
model@provider** strings via the shared `resolveModelConfig`
(`dispatch_model.go`):
- **`resolveExtractorChatConfig`** — UUID path calls
`resolveModelConfigByID` directly (one DB hit); composite path goes
through `resolveModelConfig`. Added `isBareTenantModelID` pre-check for
clear errors when a UUID doesn't exist.
- **`resolveExtractorChatTarget`** — propagates resolution errors
instead of silently returning empty driver.
- **`Chat()`** — removed `driver = "dummy"` fallback. Missing driver is
now an explicit error.
- **Removed dead code**: `splitExtractorLLID`,
`findExtractorSoleActiveInstance`.
### 4. `InjectExtractorLLMID` — fallback when no user config
(`internal/common/parser_config.go`)
Injects the tenant's global default LLM into extractor components **only
when their `llm_id` is empty**. Preserves user-selected UUID or
model@provider values.
Priority: user-configured llm_id > tenant global default > error (no
silent dummy fallback).
### 5. `ResponseHeaderTimeout` increase
(`internal/entity/models/base_model.go`)
`ResponseHeaderTimeout` 60s → 120s in `NewDriverHTTPClient`. Reasoning
models with large extraction prompts can take longer than 60s to produce
the first response token.
### 6. CJK rune-aware heading detection
(`internal/ingestion/component/chunker/title.go`)
Two byte-vs-rune bugs that only manifest on CJK text:
| Fix | What changed | Why |
|-----|-------------|-----|
| **`isColonTitle` byte offset** | `body[lastPunct+1:]` →
`body[lastPunct+runeLen:]` via `utf8.DecodeRuneInString` |
`strings.LastIndexAny` returns a byte index; `+1` skips only 1 byte,
corrupting multi-byte CJK punctuation (e.g. `。` = 3 bytes) and inflating
the rune count past the 32-rune threshold → false-positive heading
promotion. |
| **Short-line filter byte count** | `len(text) <= 1` →
`utf8.RuneCountInString(text) <= 1` | Go `len` is UTF-8 bytes; a single
CJK char (3 bytes) passed the filter, but Python's `len` returns 1 →
mismatch. |
### 7. `extractor_tag.go` — log error when llm fails
When `resolveExtractorChatTarget` returned an error, `runAutoTags` will
log error.
### 8. Python DSL prompt-key compatibility
(`internal/ingestion/component/extractor.go`)
The Resume DSL template uses Python-side key names (`sys_prompt`,
`prompts`). `NewExtractorComponent` now accepts them as fallbacks
alongside the Go names:
- `system_prompt` (Go) ← `sys_prompt` (Python) as fallback
- `prompt` (Go string) ← `prompts` (Python array `[{"role","content"}]`,
takes `[0].content`) as fallback
Mirrors the alias pattern already in `internal/agent/component/llm.go`.
`resolveInputs` accepts per-call `sys_prompt` override too.
## Remaining gaps vs Python
| Gap | Scope | Impact |
|-----|-------|--------|
| **TOC removal for TXT/MD/HTML** | Python's `remove_contents_table`
works on all text formats; Go's `remove_toc` is PDF-only. | Low —
plain-text documents rarely contain structured TOCs. |
| **Regex pattern details** | Minor differences in quantifiers, missing
H5/H6 markdown patterns, missing 4-level numbering pattern. | Low — Go's
variants are stricter; DOCX headings are covered by `ck_type` fallback.
|
## Testing
- `TestHierarchyTitleChunker_CKTypeHeadingFallback` — DOCX `ck_type`
heading promotion
- `TestHierarchyTitleChunker_ColonTitlePromotion` /
`_ColonTitleShortLine_Negative` — colon-title promotion + guard
- `TestIsColonTitle_CJKEdgeCase` / `TestIsColonTitle_ASCII_NoRegression`
— CJK byte-offset fix + ASCII regression
- `TestHierarchyTitleChunker_ColonTitlePromotion_CJK_EdgeCase` — CJK
colon edge case through full pipeline
- `TestHierarchyTitleChunker_ShortSingleCJKLineFilter` — single CJK char
filtered to body
- `TestHierarchyTitleChunker_ShortNumericLineFilter` — purely numeric
lines filtered
- `TestGetFileType_ImageExtensions` / `_ExistingFormats_NoRegression` —
image extension mapping
- `TestInjectExtractorLLMID_SkipWhenUUID` / `_SkipWhenComposite` /
`_InjectWhenEmpty` — llm_id injection guard
- `TestIsBareTenantModelID` — UUID detection
- `TestResolveExtractorChatTarget_AtSplitFallback` / `_NoDriver` — @
split fallback without DB
- `TestNewExtractorComponent_SysPromptAlias` / `_PromptsArray` /
`_PromptsArray_PromptWins` / `_SystemPromptWinsOverSysPrompt` — Python
key compatibility
- `TestBuildDOCXJSONSections_List` / `_TextBox` / `_MixedWithList` —
DOCX list/text_box parsing
- Full ingestion test suite passes (chunker, pipeline, task, service,
component packages)

feat(agent): Go ingestion pipeline progress mirroring and DeepDOC parser hardening (#16795)
feat(ingestion): mirror Go pipeline progress into the document table;
harden resume guards
- pipeline: bind the owning document via WithDocumentID; after each
TrackProgress event aggregate ingestion_task_log progress and mirror
progress/run/progress_msg back into the document table, so GET
/api/v1/datasets/{dataset_id}/documents reflects live Go pipeline
progress without a bespoke endpoint.
- canvas: extend the S3 resume guard to reject legacy no-op nodes (e.g.
ExitLoop) so component_total equals the count of progress-reporting
components and the aggregate percent can reach 100%.
- runtime/canvas: route progress through TrackProgress; add interrupt
test coverage (r3_interrupt_test.go).
- dao/entity: add IngestionTask.DocumentID column and AggregateProgress
support used by the mirror; IngestionTaskLog keeps a Checkpoint column
alongside the progress fields.
feat(deepdoc): cache DocAnalyzer inference results in Redis (1h TTL)
- Redis-backed DocAnalyzerCache decorator over inference.Client; cache
key = "ddoc:cache:<method>:" + sha256 of the JPEG-encoded image bytes
(deterministic).
- TTL = 1h; hits skip the inner HTTP call and return cached JSON; inner
errors are not cached.
refactor(deepdoc): align figure cropping with Python cropout + bounded
page caches
- CropSectionByDLA mirrors Python cropout: best-overlap DLA
figure/equation region, fallback to section bbox per page, vertical
concat on gray background.
- sliding-window page-image cache bounds peak memory to the recent
window instead of the whole PDF.
- rename DLADebug -> DLARegions across parser/chunker/tests.
refactor(parser): drop lib_type selector; align NewXxxParser with
NewPDFParser
- remove config["lib_type"] lookup and the libType param/field/switch
from all nine constructors; surface the CGO-required error at
ParseWithResult time instead of construction time; drop resolveLibType,
its test, and the four lib_type constants.
feat(utility): add a reusable workerpool for bounded concurrent
execution
- internal/utility/workerpool.go (+ tests).
refactor: translate Chinese prose comments to English in non-harness Go
files.
chore: upgrade github.com/cloudwego/eino from v0.9.9 to v0.9.12.
