+# Ticket 021: Normalize attribute selectors parsed as lists in TOON tables
+
+- **ID**: ticket-021
+- **Owner**: agent:antigravity
+- **Status**: IN_PROGRESS
+- **Workflow state**: EDIT
+- **Created**: 2026-10-02
+
+## Goal and scope
+
+Normalize CSS attribute selectors like `[data-action='foo']` when parsed into
+single-element lists by the TOON table parser. Reconstruct proper CSS attribute
+selector strings in `_testtoon_parser.py`, `_gui_expand.py`, and `_gui.py`.
+
+## Acceptance criteria
+
+- [ ] AC-01: Attribute selectors in FLOW/GUI tables expand to `[data-action='...']` rather than list representations.
+- [ ] AC-02: `GUI_CLICK` and element finding in `_gui.py` normalize any lingering list repr selectors.
+- [ ] AC-03: `tests/test_toon_attribute_selector.py` passes and governance checks pass.
+
+## Authorization
+
+SESSION_EXECUTION_AUTHORIZATION: User requested sequential testing of all functionalities with testql, fixing the library directly if GUI testing fails, and merging the changes.
+
+## Evidence boundary
+
+Operational test receipts and browser execution logs remain local state.
