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.

You are evaluating a software engineering task for repository asdf-format/asdf. Problem Statement: No longer warn but raise an exception for converters with more than 1 tag that don't implement select tag To provide backwards compatibility changes were added to: https://github.com/asdf-format/asdf/pull/1594 where including a converter (that inherits from `Converter`) in an extension which results in the converter having more than 1 tag causes a warning. For the next major version we should turn this into an error (as mentioned in the warning message). ## 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 repository is located at `/workspace`. Here is the directory tree (up to 3 levels): ``` ./CHANGES.rst ./CITATION.rst ./CONTRIBUTING.rst ./LICENSE ./MANIFEST.in ./README.rst ./asdf ./asdf/__init__.py ./asdf/_asdf.py ./asdf/_block ./asdf/_block/__init__.py ./asdf/_block/callback.py ./asdf/_block/exceptions.py ./asdf/_block/external.py ./asdf/_block/io.py ./asdf/_block/key.py ./asdf/_block/manager.py ./asdf/_block/options.py ./asdf/_block/reader.py ./asdf/_block/store.py ./asdf/_block/writer.py ./asdf/_compression.py ./asdf/_convenience.py ./asdf/_core ./asdf/_core/__init__.py ./asdf/_core/_converters ./asdf/_core/_extensions.py ./asdf/_core/_integration.py ./asdf/_core/_validators ./asdf/_display.py ./asdf/_entry_points.py ./asdf/_extern ./asdf/_extern/__init__.py ./asdf/_extern/atomicfile.py ./asdf/_helpers.py ./asdf/_jsonschema ./asdf/_jsonschema/COPYING ./asdf/_jsonschema/README.md ./asdf/_jsonschema/__init__.py ./asdf/_jsonschema/_format.py ./asdf/_jsonschema/_legacy_validators.py ./asdf/_jsonschema/_types.py ./asdf/_jsonschema/_utils.py ./asdf/_jsonschema/_validators.py ./asdf/_jsonschema/conftest.py ./asdf/_jsonschema/exceptions.py ./asdf/_jsonschema/json ./asdf/_jsonschema/protocols.py ./asdf/_jsonschema/schemas ./asdf/_jsonschema/tests ./asdf/_jsonschema/validators.py ./asdf/_node_info.py ./asdf/_tests ./asdf/_tests/__init__.py ./asdf/_tests/_block ./asdf/_tests/_helpers.py ./asdf/_tests/_regtests ./asdf/_tests/commands ./asdf/_tests/conftest.py ./asdf/_tests/core ./asdf/_tests/data ./asdf/_tests/httpserver.py ./asdf/_tests/tags ./asdf/_tests/test_api.py ./asdf/_tests/test_array_blocks.py ./asdf/_tests/test_asdf.py ./asdf/_tests/test_block_converter.py ./asdf/_tests/test_compression.py ./asdf/_tests/test_config.py ./asdf/_tests/test_deprecated.py ./asdf/_tests/test_entry_points.py ./asdf/_tests/test_extension.py ./asdf/_tests/test_file_format.py ./asdf/_tests/test_generic_io.py ./asdf/_tests/test_history.py ./asdf/_tests/test_info.py ./asdf/_tests/test_integration.py ./asdf/_tests/test_lazy_nodes.py ./asdf/_tests/test_reference.py ./asdf/_tests/test_resource.py ./asdf/_tests/test_schema.py ./asdf/_tests/test_search.py ./asdf/_tests/test_serialization_context.py ./asdf/_tests/test_stream.py ./asdf/_tests/test_tagged.py ./asdf/_tests/test_testing_helpers.py ./asdf/_tests/test_treeutil.py ./asdf/_tests/test_types.py ./asdf/_tests/test_util.py ./asdf/_tests/test_versioning.py ./asdf/_tests/test_yaml.py ./asdf/asdf.py ./asdf/commands ./asdf/commands/__init__.py ./asdf/commands/defragment.py ./asdf/commands/diff.py ./asdf/commands/edit.py ./asdf/commands/exploded.py ./asdf/commands/extension.py ./asdf/commands/info.py ./asdf/commands/main.py ./asdf/commands/tags.py ./asdf/commands/to_yaml.py ./asdf/config.py ./asdf/conftest.py ./asdf/constants.py ./asdf/exceptions.py ./asdf/extension ./asdf/extension/__init__.py ./asdf/extension/_compressor.py ./asdf/extension/_converter.py ./asdf/extension/_extension.py ./asdf/extension/_manager.py ./asdf/extension/_manifest.py ./asdf/extension/_serialization_context.py ./asdf/extension/_tag.py ./asdf/extension/_validator.py ./asdf/generic_io.py ./asdf/lazy_nodes.py ./asdf/reference.py ./asdf/resource.py ./asdf/schema.py ./asdf/search.py ./asdf/stream.py ./asdf/tagged.py ./asdf/tags ./asdf/tags/__init__.py ./asdf/tags/core ./asdf/testing ./asdf/testing/__init__.py ./asdf/testing/helpers.py ./asdf/treeutil.py ./asdf/util.py ./asdf/versioning.py ./asdf/yamlutil.py ./asv.conf.json ./benchmarks ./changes ./compatibility_tests ./compatibility_tests/README.md ./compatibility_tests/assert_file_correct.py ./compatibility_tests/common.py ./compatibility_tests/generate_file.py ./compatibility_tests/test_file_compatibility.py ./docs ./licenses ./licenses/JSONSCHEMA_LICENSE ./licenses/JSON_LICENSE ./pyproject.toml ./pytest_asdf ./pytest_asdf/__init__.py ./pytest_asdf/plugin.py ./requirements-dev.txt ./tox.ini ```

The `else` block in `asdf/extension/_converter.py` uses `RuntimeError`.
```python
else:
msg = "Converter handles multiple tags for this extension, but does not implement a select_tag method."
raise RuntimeError(msg)
```
I should probably use `RuntimeError` or another appropriate exception. The prompt says "raise an exception". Since the existing code already uses `RuntimeError` for the non-backward-compatible case, `RuntimeError` seems appropriate for the backward-compatible case as well.
Wait, if I'm changing it to an error for the next major version, I should probably use the same error message as the `else` block or a similar one.
Let's look at the current warning message again:
```python
msg = (
"Converter handles multiple tags for this extension, "
"but does not implement a select_tag method. "
"This previously worked because Converter subclasses inherited "
"the now removed select_tag. This will be an error in a future "
"version of asdf"
)
warnings.warn(msg, AsdfWarning)
```
If I change it to:
```python
msg = (
"Converter handles multiple tags for this extension, "
"but does not implement a select_tag method."
)
raise RuntimeError(msg)
```
That would be consistent with the `else` block.
Let's see where `Converter` is defined. It's likely in `asdf/extension/_converter.py` too.
Wait, if I look at the code again:
```python
if len(relevant_tags) > 1 and not hasattr(delegate, "select_tag"):
# we cannot use isinstance here because Converter supports
# virtual subclasses
if Converter in delegate.__class__.__mro__:\n # prior to asdf 3.0 Converter provided a default select_tag
# to provide backwards compatibility allow Converter subclasses
# to be registered with >1 tag but produce a warning
msg = (\n \"Converter handles multiple tags for this extension, \"\n \"but does not implement a select_tag method. \"\n \"This previously worked because Converter subclasses inherited \"\n \"the now removed select_tag. This will be an error in a future \"\n \"version of asdf\"\n )\n warnings.warn(msg, AsdfWarning)\n else:\n msg = \"Converter handles multiple tags for this extension, but does not implement a select_tag method.\"\n raise RuntimeError(msg)
```
The `if Converter in delegate.__class__.__mro__` part specifically targets those that inherit from `Converter`. The `else` part targets something else (maybe something that pretends to be a Converter but doesn't inherit from it, or some other edge case).
Actually, the comment says:
`# we cannot use isinstance here because Converter supports virtual subclasses`
If I change the warning to `RuntimeError`, I can probably simplify this whole block.
If `len(relevant_tags) > 1 and not hasattr(delegate, "select_tag")`, it should ALWAYS be a `RuntimeError`.
Let's verify if I can just simplify it to:
```python
if len(relevant_tags) > 1 and not hasattr(delegate, "select_tag"):
msg = "Converter handles multiple tags for this extension, but does not implement a select_tag method."
raise RuntimeError(msg)
```
Wait, let's see if the warning message had any specific information that should be kept.
"This previously worked because Converter subclasses inherited the now removed select_tag. This will be an error in a future version of asdf"
Since it's NOW an error, that part of the message is no longer needed (or rather, it has become a reality).
Let's create a reproduction script to see the warning in action.
I need to create a Converter that has multiple tags but no `select_tag` method and register it with an extension.
Looking at `asdf/extension/_converter.py`, I can see `Converter` class is used. Let's find where `Converter` is defined.

The `else` block in `asdf/extension/_converter.py` uses `RuntimeError`.
```python
else:
msg = "Converter handles multiple tags for this extension, but does not implement a select_tag method."
raise RuntimeError(msg)
```
I should probably use `RuntimeError` or another appropriate exception. The prompt says "raise an exception". Since the existing code already uses `RuntimeError` for the non-backward-compatible case, `RuntimeError` seems appropriate for the backward-compatible case as well.
Wait, if I'm changing it to an error for the next major version, I should probably use the same error message as the `else` block or a similar one.
Let's look at the current warning message again:
```python
msg = (
"Converter handles multiple tags for this extension, "
"but does not implement a select_tag method. "
"This previously worked because Converter subclasses inherited "
"the now removed select_tag. This will be an error in a future "
"version of asdf"
)
warnings.warn(msg, AsdfWarning)
```
If I change it to:
```python
msg = (
"Converter handles multiple tags for this extension, "
"but does not implement a select_tag method."
)
raise RuntimeError(msg)
```
That would be consistent with the `else` block.
Let's see where `Converter` is defined. It's likely in `asdf/extension/_converter.py` too.
Wait, if I look at the code again:
```python
if len(relevant_tags) > 1 and not hasattr(delegate, "select_tag"):
# we cannot use isinstance here because Converter supports
# virtual subclasses
if Converter in delegate.__class__.__mro__:\n # prior to asdf 3.0 Converter provided a default select_tag
# to provide backwards compatibility allow Converter subclasses
# to be registered with >1 tag but produce a warning
msg = (\n \"Converter handles multiple tags for this extension, \"\n \"but does not implement a select_tag method. \"\n \"This previously worked because Converter subclasses inherited \"\n \"the now removed select_tag. This will be an error in a future \"\n \"version of asdf\"\n )\n warnings.warn(msg, AsdfWarning)\n else:\n msg = \"Converter handles multiple tags for this extension, but does not implement a select_tag method.\"\n raise RuntimeError(msg)
```
The `if Converter in delegate.__class__.__mro__` part specifically targets those that inherit from `Converter`. The `else` part targets something else (maybe something that pretends to be a Converter but doesn't inherit from it, or some other edge case).
Actually, the comment says:
`# we cannot use isinstance here because Converter supports virtual subclasses`
If I change the warning to `RuntimeError`, I can probably simplify this whole block.
If `len(relevant_tags) > 1 and not hasattr(delegate, "select_tag")`, it should ALWAYS be a `RuntimeError`.
Let's verify if I can just simplify it to:
```python
if len(relevant_tags) > 1 and not hasattr(delegate, "select_tag"):
msg = "Converter handles multiple tags for this extension, but does not implement a select_tag method."
raise RuntimeError(msg)
```
Wait, let's see if the warning message had any specific information that should be kept.
"This previously worked because Converter subclasses inherited the now removed select_tag. This will be an error in a future version of asdf"
Since it's NOW an error, that part of the message is no longer needed (or rather, it has become a reality).
Let's create a reproduction script to see the warning in action.
I need to create a Converter that has multiple tags but no `select_tag` method and register it with an extension.
Looking at `asdf/extension/_converter.py`, I can see `Converter` class is used. Let's find where `Converter` is defined.

Okay, I have enough information to create a reproduction. I need: 1. A class that inherits from `Converter` (or matches its interface via `__subclasshook__`). 2. It must have `tags` property with more than 1 tag. 3. It must NOT have `select_tag` method. 4. An `Extension` that includes this converter and has tags that match the converter's tags. Let's look at `asdf/extension/_extension.py` and `asdf/extension/_manager.py` to see how converters are registered. Actually, the `ConverterProxy` is where the check happens. It seems `ConverterProxy` is instantiated when a converter is registered within an extension. Let's check `asdf/extension/_extension.py`.

The warning was caught! The `TypeError` was because I tried to iterate over `warning.message` or something.
Wait, look at the output:
`Caught warning: Converter handles multiple tags for this extension, but does not implement a select_tag method. This previously worked because Converter subclasses inherited the now removed select_tag. This will be an error in a future version of asdf`
The `TypeError` is here:
```python
for warning in w:
print(f"Caught warning: {warning.message}")
if "Converter handles multiple tags" in warning.message:
print("SUCCESS: Warning caught")
return True
```
Wait, `warning` is a `WarningMessage` object. `warning.message` is a string.
Ah, I see what happened. `pygame.warnings` might behave differently or I'm misremembering `WarningMessage`.
Actually, looking at the output:
`Caught warning: Converter handles multiple tags for this extension, but does not implement a select_tag method. This previously worked because Converter subclasses inherited the now removed select_tag. This will be an error in a future version of asdf`
The `print(f"Caught warning: {warning.message}")` worked.
Wait, is `warning.message` a string? Yes.
Is `"Converter handles multiple tags" in warning.message` failing?
Wait, if `warning.message` is a string, `in` should work.
Wait, maybe `warning` is not what I think it is.
Let's check what `w` (the recorded warnings) contains.
Actually, I can just check if any warning in `w` has that message.
Let's refine the reproduction script and just print the warning and exit if it's found.
Actually, I've already confirmed that the warning is issued. Now I can apply the fix.
The fix is to change:
```python
msg = (
"Converter handles multiple tags for this extension, "
"but does not implement a select_tag method. "
"This previously worked because Converter subclasses inherited "
"the now removed select_tag. This will be an error in a future "
"version of asdf"
)
warnings.warn(msg, AsdfWarning)
```
to:
```python
msg = "Converter handles multiple tags for this extension, but does not implement a select_tag method."
raise RuntimeError(msg)
```
Actually, I can just remove the `if Converter in delegate.__class__.__mro__` check entirely and just have one common error message.
Current code:
```python
if len(relevant_tags) > 1 and not hasattr(delegate, "select_tag"):
# we cannot use isinstance here because Converter supports
# virtual subclasses
if Converter in delegate.__class__.__mro__:\n # prior to asdf 3.0 Converter provided a default select_tag
# to provide backwards compatibility allow Converter subclasses
# to be registered with >1 tag but produce a warning
msg = (\n \"Converter handles multiple tags for this extension, \"\n \"but does not implement a select_tag method. \"\n \"This previously worked because Converter subclasses inherited \"\n \"the now removed select_tag. This will be an error in a future \"\n \"version of asdf\"\n )\n warnings.warn(msg, AsdfWarning)\n else:\n msg = \"Converter handles multiple tags for this extension, but does not implement a select_tag method.\"\n raise RuntimeError(msg)
```
Proposed change:
```python
if len(relevant_tags) > 1 and not hasattr(delegate, "select_tag"):
msg = "Converter handles multiple tags for this extension, but does not implement a select_tag method."
raise RuntimeError(msg)
```
This simplifies the code and implements the requested change.
Let's check if there are any other places where this check is done.
I'll search for `select_tag`.
