Phase 5C of startup_speedup_20260606 track.
src/markdown_helper.py imported src.markdown_table at module level:
from src.markdown_table import parse_tables, render_table
Both parse_tables and render_table are only used inside
MarkdownRenderer.render(). Removed the top-level import; the
MarkdownRenderer.render() method now does:
markdown_table = _require_warmed('src.markdown_table')
parse_tables = markdown_table.parse_tables
render_table = markdown_table.render_table
at the top of its body, before any other logic.
TESTS:
- tests/test_markdown_helper_no_top_level_table.py: 3/3 PASS (all RED -> GREEN)
- tests/test_markdown_table*.py (5 files) + test_markdown_helper_bullets.py +
test_markdown_render_robust.py: 24/24 PASS (no breakage)
EFFECTIVENESS: import src.markdown_helper no longer triggers src.markdown_table
(~250ms). For renderers that never hit a GFM table, the import is never
paid. For renderers that do, the warmup pre-loads it on _io_pool and the
render() lookup is O(1).
NEXT: Phase 5D - bulk refactor of src/gui_2.py feature-gated imports via
scripts/audit_gui2_imports.py.
