 - **Tables in chat messages now render with visible borders** (`static/style.css`): The `.msg-body` area had no table CSS, so markdown tables sent by the assistant were unstyled and unreadable. Four new rules mirror the existing `.preview-md` table styles: `border-collapse:collapse`, per-cell padding and borders via `var(--border2)`, and an alternating-row tint. Two `:root[data-theme="light"]` overrides ensure the borders and header background adapt correctly in light mode. (fixes #341)
 - **Plain URLs in chat messages are now clickable** (`static/ui.js`): Bare URLs like `https://example.com` were rendered as plain text. A new autolink pass in `renderMd()` converts `https?://...` URLs to `<a>` tags automatically. Runs after the SAFE_TAGS escape pass (protecting code blocks), before paragraph wrapping. Also applied inside `inlineMd()` so URLs in list items, blockquotes, and table cells are linked too. Trailing punctuation stripped; `esc()` applied to both href and link text. (fixes #342)
   - 11 new tests (4 in `tests/test_issue341.py`, 7 in `tests/test_issue342.py`); 813 tests total (up from 802)
+- **Test infrastructure fix** (`tests/test_sprint34.py` #349): two static-file opens used bare relative paths that failed when pytest ran from outside the repo root; replaced with `pathlib.Path(__file__).parent.parent` consistent with the rest of the suite. 813/813 now pass from any working directory.
