ROOT CAUSE: src/markdown_helper.py:render() used a 'mask text with placeholders
then re.split' approach that failed when AI responses contained CRLF or when
the same table content appeared twice. The replace() either didn't match
(CRLF mismatch) or only replaced the first occurrence, leaving the second
table as raw markdown for imgui_md to render badly. Result: the same table
appeared twice (bad rendering via imgui_md, good rendering via my new code).
FIX: rewrite render() to walk lines directly. Per-line, decide whether to
buffer for imgui_md, skip into a table renderer, or accumulate into a
code-block renderer. No text replacement needed.
- src/markdown_helper.py: new render() walks lines, handles code fences
and table intervals inline via lookup dicts.
- src/gui_2.py: render_log_management now calls load_registry() on the
newly-created LogRegistry when _log_registry was None. Previously the
initial construction populated an empty table, AND the 'Refresh Registry'
button was inside the else branch, so users had no way to load data.
User re-indented the surrounding block during debugging.
Tests:
- test_markdown_render_robust.py: 2 tests (CRLF text, duplicate content)
- test_log_management_first_open.py: 1 test (registry populated on open)
40/40 broad regression pass.
