## Summary
Fixes#15215 — attachments uploaded to an agent were not reaching the
LLM.
When a user uploads a file in an agent chat, `canvas.run` parses it into
the `sys.files` global (text content for documents, `data:image/...`
URIs
for images — see `agent/canvas.py:752-768`). But the LLM/Agent
component's
`_prepare_prompt_variables` only substitutes variables the user's prompt
template explicitly references via `{var}` placeholders. The default
prompt is `[{"role": "user", "content": "{sys.query}"}]` with no
`{sys.files}`, so the parsed attachment content never reaches the model.
In the reporter's logs, this is why the agent saw only the bare query
`附件 摘要 attachment summary` and went searching the dataset instead of
reading the uploaded PDF.
## Fix
`agent/component/llm.py` — added `_collect_sys_files()` and an
auto-injection step in `_prepare_prompt_variables`:
- If `sys.files` is non-empty **and** neither `sys_prompt` nor any entry
in `prompts` already contains `{sys.files}` (no double-injection),
split the entries into text vs. `data:image/...` URIs.
- Image URIs are merged into `self.imgs`, which the existing logic uses
to switch the chat model to `IMAGE2TEXT` and pass `images=...` to
`async_chat`.
- Text content is appended to the last `user` role message in `msg`,
mirroring how `dialog_service.async_chat_solo` handles attachments for
the non-agent chat path (`api/db/services/dialog_service.py:318-321`).
Both `LLM._invoke_async` and `Agent._invoke_async` (tool-using) go
through `_prepare_prompt_variables`, so plain LLM nodes and Agent nodes
are fixed in both streaming and non-streaming paths.
## Test plan
- [ ] Upload a PDF attachment to an agent with the default `{sys.query}`
prompt and ask "summarize the attachment" — the model should answer
from the file content rather than searching the knowledge base.
- [ ] Upload an image attachment to an agent and ask about its contents
—
the model should switch to the vision-capable LLM and answer from
the image.
- [ ] Verify that an agent whose prompt **does** include `{sys.files}`
still works and does **not** include the file content twice.
- [ ] Verify that an agent run with no attachments behaves unchanged.
- [ ] Run `uv run pytest` to make sure no existing tests regress.

### What problem does this PR solve?
This PR fixes Go admin server startup failure caused by duplicate model
aliases in conf/all_models.json.
The model provider loader builds a global lookup table from both model
name and alias values. Some aliases duplicated another model's name or
another
alias, for example amazon.titan-embed-text-v1, which caused startup to
fail with a duplicate alias error. This PR removes conflicting duplicate
aliases
while keeping all model definitions intact.
## Summary
- Normalize model alias index keys to lowercase
- Detect lowercase alias collisions during provider manager
initialization
- Fix ListModels metadata mapping for mixed-case provider aliases
This PR expands conf/all_models.json with DeepSeek model entries and
provider aliases.
Changes:
- Added DeepSeek model entries across `V4`, `V3.2`, `V3.1`, `V3`, `R1`,
`Coder`, `Math`, `VL`, `OCR`, `Prover`, `MoE`, and `LLM` series.
- Normalized model name values to lowercase canonical IDs.
- Added alias values for official DeepSeek/Hugging Face names and
provider-specific names from OpenRouter, VolcEngine, SiliconFlow,
HuaweiCloud, and QiniuCloud.
- Preserved model metadata such as max_tokens, model_types, and thinking
where applicable.
- Added Gitee ListModels tests to verify DeepSeek aliases map back to
model metadata from all_models.json.
- Added an optional Gitee integration test gated by
GITEE_LIST_MODELS_INTEGRATION=1.
