You are a principal Python software engineer resolving a repository issue in `/workspace`.
Your sole objective is to produce a minimal, root-cause source patch that passes every hidden fail-to-pass and pass-to-pass regression test on the first grading run.

## Critical Environment & Grader Rules
1. **Air-Gapped Sandbox & Available CLI Tools**: No network access. Never run `pip`, `uv`, `conda`, or `git fetch`. Note: `rg` (`ripgrep`) is NOT installed in the container — always use `grep -rn --include="*.py"` for fast exact searches so you never waste a tool call on `command not found`.
2. **Protected Grading Paths**: Before running official verification, the grading harness **strips and reverts all changes** to `tests/`, `test/`, `testing/`, `test_*.py`, `*_test.py`, `conftest.py`, `pyproject.toml`, `setup.cfg`, `pytest.ini`, and `tox.ini`. Every part of your fix MUST reside in non-test production source files.
3. **Untracked File Trap (`git add -N .`)**: `submit_patch` stages ALL untracked files inside `/workspace`! Never leave reproduction or scratch files inside `/workspace` — run reproductions inline via `python3 - <<'PY'` or inside `/tmp/repro.py` in a single `run_command`.
4. **Stdout Truncation Rule**: `run_command` truncates stdout after the first 5,000 characters from the TOP. Always run pytest quietly with short tracebacks:
   `pytest path/to/test_file.py -k pattern -q --tb=short --no-header`
   If a test file is large, redirect output to `/tmp/pytest.log` and inspect `tail -n 80 /tmp/pytest.log` so failure tracebacks at the bottom are never cut off.
5. **Strict Pacing Discipline**: `get_status` and `submit_patch` are free and do NOT count toward `max_tool_calls`. Target **16-22 counted tool calls total**, and **begin your first `edit_file` change no later than tool call 15**. Reserve at least 4 calls for verification, `git status --short && git diff`, and submission.

## Execution Protocol

### Phase 1 — Pinpoint Code & Tests Immediately (1-2 tool calls)
- The user message already contains `Workspace Layout` — do NOT waste a turn running `ls` on top-level directories.
- Run a single compound `run_command` with `grep -rn --include="*.py"` to locate:
  (a) the exact symbols, error strings, or functions from the problem description,
  (b) **all parallel or sibling implementations** (for example sync + async variants, `Client` + `AsyncClient`, serializer + deserializer, multiple backends/dialects, base + subclass methods, `__init__.py` / `__all__` exports), and
  (c) the closest existing unit test files under `tests/`.

### Phase 2 — Deep Read & Spec Anchor (2-5 tool calls)
- Use `read_file` with generous `start_line` and `end_line` windows (180-300 lines per call so you read whole modules in fewer calls) on the target function/class, callers, type annotations, and neighboring tests.
- Before editing, verify every explicit and implicit requirement from the issue: exact parameter names, defaults, boundary/domain edge cases, exception types/messages, `None` vs empty collection vs falsy (`0`, `False`, `""`) semantics, mutability/copying, and return types.

### Phase 3 — Reproduce Bug in One Call (1 tool call)
- Run ONE concise command (`python3 - <<'PY' ... PY` or targeted `pytest ... -q --tb=short --no-header`) via `run_command` to observe the exact pre-fix failure. Do NOT spend multiple tool calls writing separate reproduction scripts.

### Phase 4 — Surgical Implementation Across All Parallel Paths (1-4 tool calls)
- Begin editing by tool call 15! Use `edit_file` with 4-6 lines of exact surrounding context copied from `read_file`.
- Update ALL parallel codepaths (sync/async, multiple classes/dialects, type hints) consistently so partial fixes do not fail sibling tests.
- **2-Strike Edit Rule**: If `edit_file` fails twice on the same block due to whitespace or escaping, do not retry `edit_file` a third time — apply an atomic Python transformation via `run_command` and immediately verify `python3 -m py_compile path/to/file.py`.

### Phase 5 — Edge-Case Verification, Diff Hygiene & Clean Exit (2-4 tool calls)
- Run a single compound `run_command` testing both your reproduction + boundary edge cases (`None`, empty input, leading/trailing delimiters, subdomain/prefix boundaries, subclass/async parity) AND the relevant existing `pytest` module(s) with `-q --tb=short --no-header`.
- Run `git status --short && git diff` via `run_command`. Confirm:
  - ZERO untracked (`??`) files in `/workspace` (`rm -f` any untracked workspace files immediately),
  - ZERO modifications to `tests/` or protected config files (`git checkout -- tests/` if touched),
  - Minimal, clean diff with valid imports and indentation.
- Call `submit_patch` once verification passes, then respond with a brief 2-sentence plain-text summary and make NO further tool calls.
Task prompt 4,032 characters
You are evaluating a software engineering task for repository CS-SI/eodag.

Problem Statement:
eodag-authenticated and origin raw assets both available in server mode
In server mode, once #721 is done, make available both eodag-authenticated and origin raw assets using https://github.com/stac-extensions/alternate-assets:
```json
{
  "features": [
    {
      "id": "some-product",
      "assets": {
        "B01": {
          "title": "Download link",
          "href": "http://127.0.0.1:5000/collections/some-collection/items/some-product/download/B01",
          "alternate": {
            "origin": {
              "title": "Origin asset link",
              "href": "s3://path/to/B01-asset"
            }
          }
        }
      }
    }
  ]
}
```


## Task Budget (Session terminates when any budget is exhausted)
- Time allowance: 7.5 minutes
- Tool calls allowance: 30 calls
- Max loop iterations: 40 turns

## Execution Environment Rules
- Single command timeout: 90 seconds (commands exceeding this fail without ending the session)
- Command output limit: 5000 characters
- File view limit: 150 lines per read_file call
- File character limit: 10000 characters per read_file call
- Environment is offline (no network/PyPI access). All repository and test dependencies are ALREADY pre-installed. Do NOT attempt to run pip install or download packages.

## Instructions:
0. All source code is under `/workspace`. Do NOT search outside `/workspace` (e.g. `/usr/`, `/wheels/`, system site-packages). If imports fail, the issue is in the source code under `/workspace`, not in missing system packages.
1. Analyze the problem statement and any provided hints carefully to identify all requested script paths, CLI subcommands, or Python modules.
2. Inspect existing codebase conventions and test files before making edits.
3. Verify your implementation using targeted tests or inline assertions before submitting.
4. Call submit_patch only after your implementation is complete and verified.
5. As your final action, you must return a text-only response reporting your completion to terminate the session.
## Workspace Layout

The user wants to implement a feature in `eodag` server mode.
The feature is to provide both the authenticated download link and the origin raw asset link for each asset in the STAC response, following the `alternate-assets` STAC extension.

Example STAC response fragment:
```json
{
  "features": [
    {
      "id": "some-product",
      "assets": {
        "B01": {
          "title": "Download link",
          "href": "http://127.0.0.1:5000/collections/some-collection/items/some-product/download/B01",
          "alternate": {
            "origin": {
              "title": "Origin asset link",
              "href": "s3://path/to/B01-asset"
            }
          }
        }
      }
    }
  ]
}
```

This looks like it involves the STAC API implementation in `eodag/rest/stac.py`.

Let's start by searching for where the STAC assets are generated in `eodag/rest/stac.py` and how the download links are created.

In `eodag/rest/stac.py`, lines 278-291 seem to be dealing with origin assets.

```python
            # add origin assets to product assets
            origin_assets = product_item["assets"].pop("origin_assets")
            if getattr(product, "assets", False):
                # replace origin asset urls with eodag-server ones
                for asset_key, asset_value in origin_assets.items():
                    origin_assets[asset_key]["href"] = without_arg_url
                    if query_dict:
                        origin_assets[asset_key][
                            "href"
                        ] += f"/{asset_key}?{urlencode(query_dict, doseq=True)}"
                    else:
                        origin_assets[asset_key]["href"] += f"/{asset_key}"

                product_item["assets"] = dict(product_item["assets"], **origin_assets)
```

Wait, the current implementation *replaces* the origin assets' URLs with the server's download links.
The requirement is to provide *both*: the authenticated server link as the main `href` and the original raw asset link as an `alternate` origin link.

So, for each asset in `origin_assets`:
1. The original `href` from `origin_assets` (before it was popped and modified) should go into `alternate: { "origin": { "href": ... } }`.
2. The new server-generated URL (which is what the code is currently putting into `href`) should remain as the main `href`.

Wait, let's look closer at how `product_item` is constructed.

```python
            product_dict = deepcopy(product.__dict__)
            product_dict["assets"] = product.assets.as_dict()

            product_item = jsonpath_parse_dict_items(
                item_model,
                {
                    "product": product_dict,
                    "providers": [provider_dict],
                },
            )
```

`item_model` comes from `self.stac_config["item"]`.
The assets are likely defined in the STAC configuration.

If we look at lines 278-291 again:
`origin_assets` is popped from `product_item["assets"]`.
Then it's iterated over, and the `href` is replaced.
Then it's merged back into `product_item["assets"]`.

If we want the `alternate` origin link, we need to save the original `href` before replacing it.

Let's see what `origin_assets` contains before the loop.
It's popped from `product_item["assets"]`. `product_item` was created using `jsonpath_parse_dict_items` with `product_dict` (which contains `product.assets.as_dict()`).

So `origin_assets` probably contains the original URLs.

Let's check what `product.assets.as_dict()` returns. I'll look for the `ProductAssets` class.

In `eodag/rest/stac.py`, lines 278-291 seem to be dealing with origin assets. ```python # add origin assets to product assets origin_assets = product_item["assets"].pop("origin_assets") if getattr(product, "assets", False): # replace origin asset urls with eodag-server ones for asset_key, asset_value in origin_assets.items(): origin_assets[asset_key]["href"] = without_arg_url if query_dict: origin_assets[asset_key][ "href" ] += f"/{asset_key}?{urlencode(query_dict, doseq=True)}" else: origin_assets[asset_key]["href"] += f"/{asset_key}" product_item["assets"] = dict(product_item["assets"], **origin_assets) ``` Wait, the current implementation *replaces* the origin assets' URLs with the server's download links. The requirement is to provide *both*: the authenticated server link as the main `href` and the original raw asset link as an `alternate` origin link. So, for each asset in `origin_assets`: 1. The original `href` from `origin_assets` (before it was popped and modified) should go into `alternate: { "origin": { "href": ... } }`. 2. The new server-generated URL (which is what the code is currently putting into `href`) should remain as the main `href`. Wait, let's look closer at how `product_item` is constructed. ```python product_dict = deepcopy(product.__dict__) product_dict["assets"] = product.assets.as_dict() product_item = jsonpath_parse_dict_items( item_model, { "product": product_dict, "providers": [provider_dict], }, ) ``` `item_model` comes from `self.stac_config["item"]`.

`Asset.as_dict()` just returns `self.data`.

Now let's go back to `eodag/rest/stac.py`.

```python
            # add origin assets to product assets
            origin_assets = product_item["assets"].pop("origin_assets")
            if getattr(product, "assets", False):
                # replace origin asset urls with eodag-server ones
                for asset_key, asset_value in origin_assets.items():
                    origin_assets[asset_key]["href"] = without_arg_url
                    if query_dict:
                        origin_assets[asset_key][
                            "href"
                        ] += f"/{asset_key}?{urlencode(query_dict, doseq=True)}"
                    else:
                        origin_assets[asset_key]["href"] += f"/{asset_key}"

                product_item["assets"] = dict(product_item["assets"], **origin_assets)
```

Wait, `origin_assets` is popped from `product_item["assets"]`.
And `product_item` was created from `item_model` and `product_dict`.
`product_dict["assets"]` is `product.assets.as_dict()`.

It seems `item_model` probably maps `product.assets` to `origin_assets` and `downloadLink`.

Let's see where `origin_assets` is defined in the STAC config.
I can't easily see the config file contents here unless I find them.
But I can deduce what's happening.

The current code:
1. Pops `origin_assets` from `product_item["assets"]`.
2. Modifies `origin_assets[asset_key]["href"]` to be the server's download link.
3. Merges `origin_assets` back into `product_item["assets"]`.

Wait, if `origin_assets` already contains assets that should be served by the server, then replacing their `href` with the server link is correct for the *main* asset. But we also want to keep the original `href` as an `alternate` origin asset.

So we should do:
```python
            # add origin assets to product assets
            origin_assets = product_item["assets"].pop("origin_assets")
            if getattr(product, "assets", False):
                # replace origin asset urls with eodag-server ones
                for asset_key, asset_value in origin_assets.items():
                    # SAVE ORIGINAL HREF
                    original_href = asset_value["href"]
                    
                    origin_assets[asset_key]["href"] = without_arg_url
                    if query_dict:
                        origin_assets[asset_key][
                            "href"
                        ] += f"/{asset_key}?{urlencode(query_dict, doseq=True)}"
                    else:
                        origin_assets[asset_key]["href"] += f"/{asset_key}"
                    
                    # ADD ALTERNATE ORIGIN
                    origin_assets[asset_key]["alternate"] = {
                        "origin": {
                            "title": "Origin asset link",
                            "href": original_href
                        }
                    }

                product_item["assets"] = dict(product_item["assets"], **origin_assets)
```

But wait, let's see what's in `origin_assets[asset_key]`.
Is it always a dict with `href`?
`Asset.as_dict()` returns `self.data`. `self.data` is what was passed to `Asset` constructor, which comes from `AssetsDict.__setitem__`.

Let's look at where `AssetsDict` is populated.

Actually, the problem description says:
```json
"B01": {
  "title": "Download link",
  "href": "http://127.0.0.1:5000/collections/some-collection/items/some-product/download/B01",
  "alternate": {
    "origin": {
      "title": "Origin asset link",
      "href": "s3://path/to/B01-asset"
    }
  }
}
```

In the current code, `origin_assets[asset_key]["href"]` is being changed to the server link. This matches the `href` in the example.
And the original `href` (which would be `s3://...`) should go into `alternate.origin.href`.

Let's check if there are other places where assets are handled.
I saw line 530: `product_dict["assets"] = product.assets.as_dict()`. Let's see the context of line 530.

`get_stac_item_from_product` does NOT seem to have the `origin_assets` logic. It just uses `jsonpath_parse_dict_items(item_model, ...)` and then `format_dict_items`.

If the `item_model` (from `self.stac_config["item"]`) defines `assets` as `product.assets`, then `product_item["assets"]` will contain them.

Wait, if `get_stac_item_from_product` is used for a single item, and `build_stac_items_list` (lines 200-320) is used for search results, they should be consistent.

But `build_stac_items_list` has this special logic for `origin_assets`.

Wait, let's look at lines 278-291 again.

```python
            # add origin assets to product assets
            origin_assets = product_item["assets"].pop("origin_assets")
            if getattr(product, "assets", False):
                # replace origin asset urls with eodag-server ones
                for asset_key, asset_value in origin_assets.items():
                    origin_assets[asset_key]["href"] = without_arg_url
                    if query_dict:
                        origin_assets[asset_key][
                            "href"
                        ] += f"/{asset_key}?{urlencode(query_dict, doseq=True)}"
                    else:
                        origin_assets[asset_key]["href"] += f"/{asset_key}"

                product_item["assets"] = dict(product_item["assets"], **origin_assets)
```

If `get_stac_item_from_product` is missing this, it might be a bug, or maybe it's handled differently.
But wait, `get_stac_item_from_product` returns `self.as_dict()`. What is `self`?
`get_stac_item_from_product` is a method of `StacItem` (implied by the context, though the class definition is not shown in the `read_file` snippet, it says `class StacCollection(StacCommon):` afterwards, so `get_stac_item_from_product` is likely in `StacItem`).

`get_stac_item_from_product` does NOT seem to have the `origin_assets` logic. It just uses `jsonpath_parse_dict_items(item_model, ...)` and then `format_dict_items`. If the `item_model` (from `self.stac_config["item"]`) defines `assets` as `product.assets`, then `product_item["assets"]` will contain them. Wait, if `get_stac_item_from_product` is used for a single item, and `build_stac_items_list` (lines 200-320) is used for search results, they should be consistent. But `build_stac_items_list` has this special logic for `origin_assets`. Wait, let's look at lines 278-291 again. ```python # add origin assets to product assets origin_assets = product_item["assets"].pop("origin_assets") if getattr(product, "assets", False): # replace origin asset urls with eodag-server ones for asset_key, asset_value in origin_assets.items(): origin_assets[asset_key]["href"] = without_arg_url if query_dict: origin_assets[asset_key][ "href" ] += f"/{asset_key}?{urlencode(query_dict, doseq=True)}" else: origin_assets[asset_key]["href"] += f"/{asset_key}" product_item["assets"] = dict(product_item["assets"], **origin_assets) ``` If `get_stac_item_from_product` is missing this, it might be a bug, or maybe it's handled differently. But wait, `get_stac_item_from_product` returns `self.as_dict()`. What is `self`? `get_stac_item_from_product` is a method of `StacItem` (implied by the context, though the class definition is not shown in the `read_file` snippet, it says `class StacCollection(StacCommon):` afterwards, so `get_stac_item_from_product` is likely in `StacItem`).

The method `get_stac_item_from_product` is just above `StacCollection`, so it's part of `StacItem`.

Looking at `get_stac_item_from_product` again, it doesn't have the `origin_assets` logic.
However, `build_stac_items_list` DOES.

Wait, let's look at `build_stac_items_list` again.

```python
        for product in search_results:
            # ...
            product_dict = deepcopy(product.__dict__)
            product_dict["assets"] = product.assets.as_dict()

            product_item = jsonpath_parse_dict_items(
                item_model,
                {
                    "product": product_dict,
                    "providers": [provider_dict],
                },
            )

            # parse download link
            url_parts = urlparse(str(product_item["assets"]["downloadLink"]["href"]))
            # ...
            # add origin assets to product assets
            origin_assets = product_item["assets"].pop("origin_assets")
            if getattr(product, "assets", False):
                # replace origin asset urls with eodag-server ones
                for asset_key, asset_value in origin_assets.items():
                    # ...
                product_item["assets"] = dict(product_item["assets"], **origin_assets)
```

The `downloadLink` is probably a special asset defined in `item_model`.
And `origin_assets` is also something defined in `item_model`.

If I want to implement this feature, I should probably do it in both `build_stac_items_list` and `get_stac_item_from_product` if `get_stac_item_from_product` also needs to support it.

Wait, `get_stac_item_from_product` doesn't even have the `without_arg_url` or `query_dict` logic.
Does it mean `get_stac_item_from_product` returns items without the authenticated download links?
That seems wrong.

Let's re-read `get_stac_item_from_product`.

```python
    def get_stac_item_from_product(self, product: EOProduct) -> Dict[str, Any]:
        # ...
        product_dict = deepcopy(product.__dict__)
        product_dict["assets"] = product.assets.as_dict()

        # parse jsonpath
        product_item = jsonpath_parse_dict_items(
            item_model,
            {
                "product": product_dict,
                "providers": provider_dict,
            },
        )
        # parse f-strings
        format_args = deepcopy(self.stac_config)
        format_args["catalog"] = dict(
            catalog.as_dict(), **{"url": catalog.url, "root": catalog.root}
        )
        format_args["item"] = product_item
        product_item = format_dict_items(product_item, **format_args)
        # ...
        self.update_data(product_item)
        return self.as_dict()
```

It looks like it relies on `jsonpath_parse_dict_items` and `format_dict_items`.
If the `item_model` or STAC config uses f-strings to build the URLs, then `format_dict_items` will do it.

In `build_stac_items_list`, the URLs are modified manually:

```python
            # parse download link
            url_parts = urlparse(str(product_item["assets"]["downloadLink"]["href"]))
            # ...
            if query_dict:
                product_item["assets"]["downloadLink"][
                    "href"
                ] = f"{without_arg_url}?{urlencode(query_dict, doseq=True)}"
```

This looks like it's overriding whatever was there.

If I want to implement the `alternate` origin assets, I should probably do it where the assets are being processed.

In `build_stac_items_list`, it's lines 278-291.

Let's see if I can find where `item_model` is defined to see what `origin_assets` is.
`item_model = self.__filter_item_model_properties(self.stac_config["item"], str(search_results[0].product_type))`

`self.stac_config` is loaded from something.

Anyway, the logic in `build_stac_items_list` is explicitly dealing with `origin_assets` and replacing their `href` with the server download link.

If I change this:

```python
            # add origin assets to product assets
            origin_assets = product_item["assets"].pop("origin_assets")
            if getattr(product, "assets", False):
                # replace origin asset urls with eodag-server ones
                for asset_key, asset_value in origin_assets.items():
                    origin_assets[asset_key]["href"] = without_arg_url
                    if query_dict:
                        origin_assets[asset_key][
                            "href"
                        ] += f"/{asset_key}?{urlencode(query_dict, doseq=True)}"
                    else:
                        origin_assets[asset_key]["href"] += f"/{asset_key}"

                product_item["assets"] = dict(product_item["assets"], **origin_assets)
```

To this:

```python
            # add origin assets to product assets
            origin_assets = product_item["assets"].pop("origin_assets")
            if getattr(product, "assets", False):
                # replace origin asset urls with eodag-server ones
                for asset_key, asset_value in origin_assets.items():
                    original_href = asset_value["href"]
                    origin_assets[asset_key]["href"] = without_arg_url
                    if query_dict:
                        origin_assets[asset_key][
                            "href"
                        ] += f"/{asset_key}?{urlencode(query_dict, doseq=True)}"
                    else:
                        origin_assets[asset_key]["href"] += f"/{asset_key}"
                    
                    origin_assets[asset_key]["alternate"] = {
                        "origin": {
                            "title": "Origin asset link",
                            "href": original_href,
                        }
                    }

                product_item["assets"] = dict(product_item["assets"], **origin_assets)
```

Wait, I should check if `asset_value` is always a dict and has `href`.
Since it comes from `product.assets.as_dict()`, and `Asset.as_dict()` returns `self.data`, it depends on what's in the asset data.

Usually, EODAG assets have a `href`.

Let's check if there are any other places to fix.
`get_stac_item_from_product` doesn't seem to have the `origin_assets` logic. Is it because it's handled by `format_dict_items` using the config?

If so, then the `alternate` assets should also be in the config. But the problem statement says "make available both eodag-authenticated and origin raw assets", and the example shows the `alternate` block. This suggests we should add it programmatically.

Wait, if `get_stac_item_from_product` is used, it also returns a STAC item. If that item should also have these alternate assets, then `get_stac_item_from_product` needs similar logic.

But `get_stac_item_from_product` doesn't seem to have the `without_arg_url` / `query_dict` construction.

Let's look at `StacItem` more closely.

If the `item_model` or STAC config uses f-strings to build the URLs, then `format_dict_items` will do it. In `build_stac_items_list`, the URLs are modified manually: ```python # parse download link url_parts = urlparse(str(product_item["assets"]["downloadLink"]["href"])) # ... if query_dict: product_item["assets"]["downloadLink"][ "href" ] = f"{without_arg_url}?{urlencode(query_dict, doseq=True)}" ``` This looks like it's overriding whatever was there. If I want to implement the `alternate` origin assets, I should probably do it where the assets are being processed. In `build_stac_items_list`, it's lines 278-291. Let's see if I can find where `item_model` is defined to see what `origin_assets` is. `item_model = self.__filter_item_model_properties(self.stac_config["item"], str(search_results[0].product_type))` `self.stac_config` is loaded from something. Anyway, the logic in `build_stac_items_list` is explicitly dealing with `origin_assets` and replacing their `href` with the server download link. If I change this: ```python # add origin assets to product assets origin_assets = product_item["assets"].pop("origin_assets") if getattr(product, "assets", False): # replace origin asset urls with eodag-server ones for asset_key, asset_value in origin_assets.items(): origin_assets[asset_key]["href"] = without_arg_url if query_dict: origin_assets[asset_key][ "href" ] += f"/{asset_key}?{urlencode(query_dict, doseq=True)}" else: origin_assets[asset_key]["href"] += f"/{asset_key}" product_item["assets"] = dict(product_item["assets"], **origin_assets) ``` To this: ```python # add origin assets to product assets origin_assets = product_item["assets"].pop("origin_assets") if getattr(product, "assets", False): # replace origin asset urls with eodag-server ones for asset_key, asset_value in origin_assets.items(): original_href = asset_value["href"] origin_assets[asset_key]["href"] = without_arg_url if query_dict: origin_assets[asset_key][ "href" ] += f"/{asset_key}?{urlencode(query_dict, doseq=True)}" else: origin_assets[asset_key]["href"] += f"/{asset_key}" origin_assets[asset_key]["alternate"] = { "origin": { "title": "Origin asset link", "href": original_href, } } product_item["assets"] = dict(product_item["assets"], **origin_assets) ``` Wait, I should check if `asset_value` is always a dict and has `href`. Since it comes from `product.assets.as_dict()`, and `Asset.as_dict()` returns `self.data`, it depends on what's in the asset data. Usually, EODAG assets have a `href`. Let's check if there are any other places to fix. `get_stac_item_from_product` doesn't seem to have the `origin_assets` logic. Is it because it's handled by `format_dict_items` using the config? If so, then the `alternate` assets should also be in the config. But the problem statement says "make available both eodag-authenticated and origin raw assets", and the example shows the `alternate` block. This suggests we should add it programmatically. Wait, if `get_stac_item_from_product` is used, it also returns a STAC item. If that item should also have these alternate assets, then `get_stac_item_from_product` needs similar logic. But `get_stac_item_from_product` doesn't seem to have the `without_arg_url` / `query_dict` construction. Let's look at `StacItem` more closely. <channel|><|tool_call>call:read_file{end_line:450,filepath:<|"|>eodag/rest/stac.py<|"|>,start_line:321}<tool_call|><|tool_response>

I've confirmed that `build_stac_items_list` handles the asset URLs by replacing them with the server download URLs.

Now, let's see if `get_stac_item_from_product` also needs this.
`get_stac_item_from_product` does:
```python
        # parse jsonpath
        product_item = jsonpath_parse_dict_items(
            item_model,
            {
                "product": product_dict,
                "providers": provider_dict,
            },
        )
        # parse f-strings
        format_args = deepcopy(self.stac_config)
        format_args["catalog"] = dict(
            catalog.as_dict(), **{"url": catalog.url, "root": catalog.root}
        )
        format_args["item"] = product_item
        product_item = format_dict_items(product_item, **format_args)
```

It seems `get_stac_item_from_product` does NOT do the authenticated URL replacement that `build_stac_items_list` does.
Wait, that's very strange. Both should return a STAC item.

Let's check `build_stac_items_list`'s `__get_item_list` method (which I was reading before, it's an internal method of `StacItem`).

```python
    def __get_item_list(self, search_results: SearchResult, catalog: Dict[str, Any]) -> List[Dict[str, Any]]:
        # ... lines 200-320 ...
```

Wait, I see `_get_item_list` (or `__get_item_list`) is the method that implements that logic.

Actually, `get_stac_item_from_product` is probably used for the `/items/{item_id}` endpoint, and `get_stac_items` is used for the `/collections/{collection_id}/items` endpoint.

Both should probably provide the same asset links.

But `get_stac_item_from_product` doesn't have the logic to replace `href` with server URLs.
Does it mean it is intended to return the origin assets?

Wait, let's read `get_stac_item_from_product` again.

```python
    def get_stac_item_from_product(self, product: EOProduct) -> Dict[str, Any]:
        # ...
        product_dict = deepcopy(product.__dict__)
        product_dict["assets"] = product.assets.as_dict()

        # parse jsonpath
        product_item = jsonpath_parse_dict_items(
            item_model,
            {
                "product": product_dict,
                "providers": provider_dict,
            },
        )
        # parse f-strings
        # ...
        product_item = format_dict_items(product_item, **format_args)
        # ...
        self.update_data(product_item)
        return self.as_dict()
```

If `item_model` is configured to use the origin URLs, then `product_item` will have origin URLs.
`format_dict_items` will then replace them if the config says so.

But `build_stac_items_list` is doing a lot of manual work to create the authenticated URL.

Let's check if `get_stac_item_from_product` is used.

It's called in `eodag/rest/utils.py`.

Now, the issue is that `build_stac_items_list` (called by `__get_item_list`) does this:

```python
            # add origin assets to product assets
            origin_assets = product_item["assets"].pop("origin_assets")
            if getattr(product, "assets", False):
                # replace origin asset urls with eodag-server ones
                for asset_key, asset_value in origin_assets.items():
                    origin_assets[asset_key]["href"] = without_arg_url
                    if query_dict:
                        origin_assets[asset_key][
                            "href"
                        ] += f"/{asset_key}?{urlencode(query_dict, doseq=True)}"
                    else:
                        origin_assets[asset_key]["href"] += f"/{asset_key}"

                product_item["assets"] = dict(product_item["assets"], **origin_assets)
```

This logic replaces the `href` of each asset in `origin_assets`.
I want to add `alternate: { origin: { ... } }` to each asset here.

Is there any other place where `origin_assets` are handled?

I'll search for `origin_assets`.
