## Summary
Three groups of changes across the Go ingestion pipeline:
### 1. DOCX parsing improvements
- **docx_parser.go**: Enhanced DOCX parsing with better structure
extraction and media handling
- **docx_parser_cgo_test.go**, **docx_parser_test.go**: Companion tests
- **office_parsers_no_cgo.go**: Stub sync for non-CGO builds
### 2. Email (.eml) parsing: base64 Content-Transfer-Encoding decoding
- **email_parser.go** (`decodeCTE`): Added Content-Transfer-Encoding
decoding for base64 and quoted-printable. Go's `mime/multipart.Reader`
does not decode Content-Transfer-Encoding automatically, so attachments
with `Content-Transfer-Encoding: base64` remained base64-encoded in the
output. The new `decodeCTE` helper is called after reading each
multipart part's raw bytes in `readMailBody`, mirroring Python's
`part.get_payload(decode=True)`.
- **email_parser_test.go**: Two new tests — simple base64 attachment and
nested multipart/alternative with base64 attachment.
### 3. Extractor LLM driver fix + ModelDriver consolidation
- **extractor.go**: Fixed a bug where the Extractor component used
`ModelFactory.CreateModelDriver()`, which creates bare model instances
without API keys or provider configuration. Switched to
`models.GetPreconfiguredDriver()` which resolves the actual
pre-configured driver from `ProviderManager`, matching the codepath used
by `llm.go`. This fixes auto keyword/question extraction in DSL
pipelines that require LLM calls.
- **get_driver.go** (new): Extracted shared `GetPreconfiguredDriver()`
from `llm.go:newChatModelDriver()` so both `llm.go` and `extractor.go`
use the same codepath.
- **get_driver_test.go** (new): Tests for the shared driver resolution.
- **llm.go**: Replaced inline driver resolution with
`models.GetPreconfiguredDriver()`.
### 4. Chunker fixes and observability
- **group.go** (`extractLineRecords`): Fixed to also read `markdown` and
`html` payload keys — previously it only read `text`/`content`, causing
GroupTitleChunker to silently return empty results for markdown-format
parser output.
- **common.go** (`compileDelimPattern`): Aligned with Python's
`_compile_delimiter_pattern` — only backtick-wrapped delimiters produce
an active regex pattern; plain delimiters are not compiled into the
split regex.
- **token.go** (`applyChildrenDelim`): Set `DocType` and `CKType` to
`"text"` on created ChunkDocs so the token-size merge path correctly
identifies and merges text segments.
- **parser.go**, **extractor.go**, **tokenizer.go**, **group.go**,
**hierarchy.go**: Added debug-level logging for pipeline diagnostics.
- **parser_dispatch_test.go**, **group_test.go**: New tests.
## Verification
- All Go tests pass: `bash build.sh --test ./internal/parser/parser/...`
and `bash build.sh --test ./internal/ingestion/component/...`
- Build succeeds: `bash build.sh --go`
## Summary
- Load the Agent history window with Python-compatible defaults.
- Include prior conversation messages in ReAct prompts without
duplicating the current user input.
## Testing
- `bash build.sh --test ./internal/agent/...`
- `bash build.sh --test ./internal/service/...`

### Summary
`agent/tools/google.py` indexes `search["organic_results"]` directly
after `GoogleSearch(params).get_dict()`. serpapi returns `{"error":
...}` **without** an `organic_results` key on realistic conditions — an
invalid API key, an exhausted plan/quota, or a query that matched
nothing. that raised `KeyError('organic_results')`, which the tool's
retry loop then surfaced to the model as the opaque `"Google error:
'organic_results'"` instead of the real reason.
this guards the missing key and raises serpapi's actual `error` message
(with a clear fallback) into the existing retry/`_ERROR` path, so the
model sees e.g. `"Google error: Invalid API key."`. valid responses are
unchanged.
adds `test/unit_test/agent/tools/test_google_unit.py` covering the
error-response path (asserts the real message is surfaced, no
`KeyError`) and the normal result path, mirroring the existing
`test_googlescholar.py` pattern (skips when the `serpapi` SDK is
absent).

## Summary
Align the Go ingestion pipeline with Python's `image` → `img_id`
persistence semantics, and unify the chunk-id computation across all
paths.
### Changes
**1. Image upload at chunker stage **
- Add `ImageUploader` type and `DefaultImageUploader` in
`internal/ingestion/component/image_uploader.go` — the write-side
counterpart to `FetchBinary`, storing raw image bytes at `(bucket=kbID,
key=chunkID)`, no re-encoding.
- Add `uploadOneImage` — pure upload primitive (bytes in, `img_id` out),
does not touch chunk maps.
- Add `uploadChunkImages` / `uploadChunkImage` — caller-side helper:
decodes `image` from a chunk, uploads bytes, writes `ck["img_id"]`,
`delete(ck,"image")` , bounded by a process-wide semaphore (default 10,
env `MAX_CONCURRENT_MINIO`).
- Wire via `imageUploadDecorator` in `register.go`: every chunker runs
the upload pass at invocation time, writing `ck["id"]` before upload and
dropping image bytes right after — peak memory = single chunk image
lifetime.
**2. Unify chunk-id computation**
- Consolidate three separate id-computation paths (`component.ChunkID`,
`task.ChunkID`, inline `FormatUint` in API) into one:
`common.ChunkID(docID, text string)`, using `%016x` +
`xxhash.Sum64String(text+docID)` (matching Python `hexdigest()`).
- The chunker decorator writes `ck["id"]` via `common.ChunkID`; the
persist stage (`ProcessChunksForPipeline`) falls back to the same
function (`if !exists id`).
- The API AddChunk path now also calls `common.ChunkID` instead of the
divergent `FormatUint(xxhash.Sum64(...))` — fixing a pre-existing
inconsistency.
- Delete `internal/ingestion/component/chunk_id.go` and
`internal/ingestion/task/chunk_builder.go` (both were pure forwarding
shells).
**3. Preserve `img_id` (never deleted)**
- `img_id` is a persistent index field (Infinity, OB) and the only
consumer-side reference for image retrieval; it is NEVER removed from
the chunk map. Only `image` (raw data URL) is dropped after upload.
**4. PPT parser support**
Previously PPT parsing failed. Add support to parse.
### Key design decisions
| Decision | Choice |
|----------|--------|
| Upload timing | Chunker stage (not persist), so image bytes are
dropped immediately — bounds peak memory to one chunk image |
| Upload concurrency | Process-wide semaphore, default 10 (matches
Python `minio_limiter`), env `MAX_CONCURRENT_MINIO` |
| Image encoding | Store as-is, no JPEG re-encoding (unlike Python) |
| `img_id` format | `"<kb_id>-<chunk_id>"` — matches Python
task_executor path |
| id function | Single `common.ChunkID(docID, text)`, concatenation
`text+docID` inside hash (matching Python) |
| `removeInternalChunkFields` | Retains `delete(ck,"image")` as
defensive fallback for non-chunker paths |
### Files touched
| File | Change |
|------|--------|
| `internal/common/format.go` | Add `ChunkID(docID, text)` |
| `internal/common/format_test.go` | Add ChunkID golden-value test |
| `internal/ingestion/component/image_uploader.go` | Add `ImageUploader`
type + `DefaultImageUploader` |
| `internal/ingestion/component/chunker/image_upload.go` | Add
`uploadOneImage`, `uploadChunkImages`, `uploadChunkImage`,
`decodeChunkImage`, semaphore |
| `internal/ingestion/component/chunker/image_upload_test.go` | Tests:
upload/drop, skip, no-image, concurrency, missing-id error |
| `internal/ingestion/component/chunker/register.go` | Add
`imageUploadDecorator` (writes `ck["id"]`, runs upload) |
| `internal/ingestion/task/chunk_process.go` | Use `common.ChunkID` for
persist fallback |
| `internal/service/chunk/chunk.go` | Use `common.ChunkID` instead of
`FormatUint` |
| `internal/ingestion/component/chunk_id.go` | **Deleted** (moved to
`common`) |
| `internal/ingestion/task/chunk_builder.go` | **Deleted** (shell, no
callers left) |
| `internal/ingestion/task/chunk_builder_test.go` | **Deleted** (test
migrated to `common/format_test.go`) |
### Verification
```
bash build.sh --test ./internal/service/chunk/... ./internal/common/... ./internal/ingestion/component/... ./internal/ingestion/task/...
→ ok service/chunk / common / component / chunker / schema / task
```
### Summary
`agent/tools/github.py` indexes `response["items"]` directly after
`requests.get(...).json()`. the github search api returns `{"message":
...}` **without** an `items` key on realistic conditions — a rate limit
(403/429; this tool sends no auth token, so the unauthenticated ~10
req/min search limit is easy to hit) or an invalid query (422). that
raised `KeyError('items')`, which the tool's retry loop then surfaced to
the model as the opaque `"GitHub error: 'items'"` instead of the real
reason.
this guards the missing key and raises the api's actual `message` (with
a clear fallback) into the existing retry/`_ERROR` path, so the model
sees e.g. `"GitHub error: API rate limit exceeded ..."`. valid responses
are unchanged.
adds `test/unit_test/agent/tools/test_github_unit.py` covering the
rate-limit response (asserts the real message is surfaced, no
`KeyError`) and the normal result path.
