In `@integration-tests/tests/data/text_singlefile/metadata.json`:
- Around line 5-6: Update the timestamp values in metadata.json so they
accurately reflect the log events: change the "begin_ts" and "end_ts" JSON
fields from 1427089710000 to 1427089710122 (the actual event epoch milliseconds
for 2015-03-23 05:48:30,122) so the metadata window matches the timestamps in
simple.txt.

In `@integration-tests/tests/fixtures/path_configs.py`:
- Line 38: PackagePathConfig is being constructed with
integration_tests_project_root as test_root_dir which causes
PackagePathConfig.__post_init__ to mkdir temp_config_dir under the project root;
change the constructor call to pass integration_test_path_config.test_cache_dir
(the same cache dir used by CompressionTestPathConfig and
ConversionTestPathConfig) so temp_config_dir is created under the dedicated
cache directory and aligns behavior across PackagePathConfig,
CompressionTestPathConfig and ConversionTestPathConfig.

In `@integration-tests/tests/test_log_converter.py`:
- Around line 37-40: The current calculation of num_log_events opens files
directly in a generator expression, risking leaked file handles; change the
logic to iterate over text_singlefile.metadata.file_names with an explicit with
context manager when opening (text_singlefile.logs_path /
file_name).open(encoding="utf-8") so each file is closed deterministically,
e.g., open each file inside a with block and sum lines (sum(1 for _ in fh)) into
num_log_events; update the code around the num_log_events computation to use
this pattern.

In `@integration-tests/tests/test_log_converter.py`:
- Around line 86-90: The current loop over lines uses substring containment (if
f"TEST{idx + 1}" not in message) which yields false-positives for TEST1 matching
TEST10/11 and also assumes deterministic ordering for equal timestamps; update
the validation in the loop that processes event/message (variables event,
message, idx) to use message.endswith(f"TEST{idx + 1}") to avoid substring
matches, and for robustness against non-deterministic ordering of
identical-timestamp events replace the positional checks with an
order-independent comparison: collect all extracted TEST labels from messages
and compare that set/list against the expected set of {"TEST1",..."TEST11"} (or
assert sorted lists) instead of relying on sequential idx matching.

Inline comments:
In `@integration-tests/tests/fixtures/downloaded_datasets.py`:
- Around line 36-47: In DownloadedDataset.__post_init__, add a one-line comment
explaining that object.__setattr__ is intentionally used to bypass frozen=True
so derived/normalized fields (name, tarball_path, extraction_dir) can be set
after construction; then either (A) change the dataclass API to make the raw
constructor value an InitVar (e.g., name_input) or mark name as init=False and
compute/assign the normalized name there, or (B) if keeping the current
signature, document in the class docstring that the constructor argument for
name is normalized (stripped) and may differ from the supplied value so callers
are not surprised. Ensure the comment references __post_init__,
object.__setattr__, and the fields name/tarball_path/extraction_dir.
- Line 95: Update the docstring for the function that returns a
DownloadedDataset so the article is correct: change the return description from
"An DownloadedDataset instance providing metadata for the downloaded logs." to
"A DownloadedDataset instance providing metadata for the downloaded logs." —
locate the docstring referencing DownloadedDataset (the function that returns a
DownloadedDataset) and fix the ":return:" line accordingly.

Outside diff comments:
In `@integration-tests/tests/conftest.py`:
- Around line 12-17: The pytest_plugins list in conftest.py is missing the
module that defines the hive_24hr and postgresql fixtures; either add
"tests.fixtures.downloaded_datasets" to the pytest_plugins array so pytest
registers those fixtures (pytest_plugins variable) or delete the unused fixture
definitions from tests/fixtures/downloaded_datasets.py (fixtures named hive_24hr
and postgresql) if they aren’t needed; update accordingly and run tests to
ensure no import/fixture-not-found errors remain.
