Inline comments:
In `@CHANGELOG.md`:
- Around line 8-14: Insert blank lines after the 0.1.4, Added, and Fixed
headings in the changelog, preserving the existing entry content and heading
order.
In `@tests/test_handler.py`:
- Around line 379-404: Update test_emit_racing_close_drops_instead_of_orphaning
to call handler.close() once the emitter is blocked, before release.set(),
instead of assigning handler._closed directly; preserve the assertions that the
emit is dropped and close remains idempotent.
In `@tests/test_overflow.py`:
- Around line 153-159: Update test_split_keeps_markdown_v2_escape_pairs_whole to
prepend a one-character prefix before the repeated MarkdownV2 escape pairs, then
assert each part body has an even trailing backslash count in addition to
preserving byte-for-byte reconstruction. Use the existing _strip_header helper
when inspecting part bodies.
- Around line 148-150: Update test_safe_cut_odd_run_respects_floor to pass a
literal backslash followed by “a” by using a raw string for the first argument
to _safe_cut, preserving the existing floor and expected cut assertions.
In `@tg_logging_handler/config.py`:
- Around line 125-135: The response handling around response.json() must
validate that the decoded value is an object before accessing ok, and require
body.get("ok") to be exactly True rather than merely truthy. Convert scalar/list
JSON and non-boolean ok values into the existing TelegramConfigError path, and
add tests covering both cases.
In `@tg_logging_handler/overflow.py`:
- Around line 80-83: The marker truncation in the overflow handling must remain
MarkdownV2 parse-safe: update the marker logic near _safe_cut so limits 4 and 15
cannot leave a trailing backslash, using _safe_cut or a parse-safe fallback
while preserving the max_length cap and remaining text budget. Add boundary
tests in tests/test_overflow.py covering both limits.
In `@tg_logging_handler/sender.py`:
- Line 86: Update the httpx.Client initialization in the sender setup to disable
redirect following, preserving the timeout configuration. Add a regression test
that returns a 302 with a Location header and verifies no redirected sendMessage
request is treated as successful.
In `@tg_logging_handler/worker.py`:
- Around line 91-95: Fix the shutdown ordering between WorkerThread.shutdown()
and close() so the worker cannot exit on _shutdown_event while a late SHUTDOWN
sentinel remains queued; enqueue SHUTDOWN before setting the event, or remove
the late enqueue path. Add a deterministic regression test covering shutdown
with an empty queue and the interleaved sentinel enqueue, verifying queue.join()
completes.

Store the batch file with CRLF line endings.
Static analysis reports LF-only line endings. Convert this .bat file to CRLF to avoid Windows batch parser failures.
🧰 Tools
🪛 Blinter (1.1.7)
[error] 1-1: Unix line endings detected. Explanation: Batch file uses Unix line endings (LF-only) which can cause GOTO/CALL label parsing failures and script malfunction due to Windows batch parser 512-byte boundary bugs. Recommendation: Convert file to Windows line endings (CRLF). Use tools like dos2unix, notepad++, or configure git with 'git config core.autocrlf true'. Context: File uses Unix line endings (LF-only) - 9 LF sequences found
(E018)
[warning] 8-8: Missing exit code. Explanation: Script doesn't set appropriate exit codes to indicate success or failure. Recommendation: Add EXIT /b 0 for success or EXIT /b 1 for errors at script end. Context: Script can reach end of file without explicit EXIT statement

📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win
test_stop_false_after_capped_wait_keeps_collecting never reaches the stop poll.
Both records are already queued, so the mid-batch get never raises queue.Empty. With the scripted ticks (0.0, 0.0, 0.0, 5.0), the third iteration computes remaining == 0 and breaks before any wait. The stop is not None and stop() branch and the following continue in BatchAccumulator.collect stay uncovered, so the test passes for the wrong reason.
Drive the empty capped wait explicitly: queue one record, then let the queue report Empty while remaining still exceeds _MAX_RECORD_WAIT.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
